Year End 2013

Remarkably, December is only -.6 off average and has 73% of normal precip, so still on the dry side.  Snowfall of 14 inches is just above normal.

DXR for the year was -1.4 per graphic below, but oddly was one of the few stations below normal for temps.

DXR was close to normal for precip, certainly not a drought year, although the last few months were dry.  Thunderstorms drove the difference across the state.

Snowfall was slightly above normal, with Bridgeport scoring the most in an unusual winter

Mid Dec

12-16  most consensus in models for tomorrow's clipper. 2-4 inches with a slight chance of 6". Should be quick. Timing is tough as snow starts around 7am and picks up around 10-12. Then it's over by 2.
12 nam precip .28
12z gfs precip .23
0z  ecmwf precip .14
Cmc is .5 graphically.

12-15. Started at daybreak, 2" by noon, then a lull. 6" by 2am when it switched to zr for an hour or so.  Most interesting aspect was the temp drop from 19 at daybreak to 16 for all the daytime.  Temps did go up to 30 overnite, but the models were off by at least 5 degrees for most of the storm.  Mental note that with strong high in place, models overestimate temps.  Also most precip came through before the 925 line made it into the area.

12-13
0z Nam all snow, in the 12 inch range (see below)
6z NAM is all snow with about 1.25 qpf
 0z euro has .65 qpf before the next 6 hrs mixes/rains, map has 6 inches
0z gfs had us in 6+ range on snow map
6z gfs has .57 qpf before mixing issues
CMC has .5-.75 - brings low in closer, but keeps 850 cold until most of precip passes
UKMET farthest north - brings primary to pa, forms secondary over us.  But front loads precip
I'm not buying the warmup past freezing though at the surface.  Could be rough period of sleet/freezing rain. Hoping that the moisture moves in faster than the temp change, as it usually does.
NWS has 6-10 and winter storm watch

Euro

GFS

NAM

12-12
0z Euro - cold south, stretched out over two days. at 12z sat with .03 qpf to 0z Mon with .03 qpf. In between .44 qpf total, all snow. 850's get to -.4 at the warmest, snow map with 3-6
0z gfs - similar to Euro, stretched out lp. Ends quicker and has more qpf per 6hr. Brief rise above 0 at 850 causes mix early sunday, surface temps not over freezing. qpf .5-.75 snow accum 3-6
6z gfs is colder, with temps at 850 barely making it over freezing (0.3). Wetter with .77 qpf with .28 of that above freezing at 850, but below at 925, so sleet likely. Snow map with 6-9 inches. Precip from 12z sat to 18z sun.
0z NAM - still far out for NAM but it has a very different solution. It keeps the northern branch stronger, makes the coastal stonger too, but hugging the coast, torching the 850 temps to over 5. Whole of NE gets rain, but only after front end snows. It brings in snow 12-15z sat, keeps it light until 0-3z sun, at 6z sun, the 850 line moves tot he ct/ma border, by 9z its into VT. Seems too fast. Total qpf around an inch. Snow map of 3-5 inches for most of the area.
6z nam - same time frame as 0z, a bit cooler at 850, 850 line is over us at 6z sun. LP Runs right along li coast. QPF is .75-1 north of 84, 1-1.25 south. 4-6 inches on snow map
12z nam - starting to get colder. Snow map with much of CT over 6 and parts over 9. 850 line never lifts out of CT, stalls north of 84 though. QPF is down with most of the state .75-1 and only the far E slice of CT and RI getting 1-1.25 12-11
GFS and Euro still in agreement with weak system - qpf over 6 hrs never greater than .17.  0 lines are around 0 at their warmest, with the 18z gfs going to .1 for less than 6 hrs with little precip.  Based on qpf and a 15:1 ratio, its 6 inches out of both.  CMC continues higher output - .5 to .75 w ct, with .75-1 east ct. NAM came in looking good at 18z, but weak 1008 low off Cape may, UKMET at 72 with tx low, 96 over BM, only 1004


Morning
GFS, CMC, Euro, DGEX all on same track - LP drops from the plains, TX, LA, AL, GA, off NC/VA.  Euro is slower at that point, CMC is closer to the coast, GFS is faster.  All with mslp of 1012, to 1008 to 1004 to 1000.  None have any solid amount of precip. .4qpf for the area now.  Odd alignment of model solutions. Euro is all snow, GFS has some brief mix, CMC is half/half, DGEX has brief mix.

UKMET is faster, weaker and farther north, but only have h96 and h120 data.

CMC has most QPF .75-1.0

 12-10
gfs
0z - LP in tx, reforms in AL, goes up coast, over NJ to LI to CCOd as 996 low.  Snow to mostly rain
6z LP in tx, doesnt really organize well, moves in a broad area up to NJ as 1000, ccod 996, colder, probably equal snow and rain
12z LP in Tx, falls apart, reforms off NJ, but as a secondary with another low over wny. Much colder, nearly all snow, over 12 inches.
18z - same  - takes LP over TX, turns into blob, reforms this time closer to LI.  Probably half snow, half rain.
CMC 12z takes a 996 low west of Buffalo, forms new 1000 lp off NJ, tracks inside BM.   Very close to all snow - right on the line for a portion of it.

0z euro respawns off NJ to over CT.  Snow to mostly rain
12z Euro - lp in panhandle tx, falls apart, reforms off Delmarva, deepens rapidly, hugs coast off ACY, then goes inside BM as 988 low
Euro is more amped, gfs a bit flatter.
UKMET is weaker, takes double barrel approach - 0z has secondary on the coast, 12z out east of BM.  
.DGEX rides up the apps to right over CT, as does NAVGEM
GFS Ens have the low coming up out of tx to buffalo, hinting at secondary

12-9 -snow for tomorrow.  Euro with .19 qpf, GFS .4 and NAM .38.  Trending in a higher manner.  Could see 2-4 inches, NWS looking for 1-2, but even the Euro output is 2 inches.  Euro ens are also over .25 Its a quick and light event, but look for a band or two which may surprise.

Next down the pike is the 14th - 12z euro is a bit close to the coast, bringing mix.  0z euro was at the BM bringing all snow, and a bunch of it.   12 gfs brings storm right over us, mostly rain.  6z and 0z slides wave off obx, limited moisture, all snow. 18z GFS track is odd, it brings a low up the oh valley from the gulf, amorphously slides it due east, where it reforms off NJ and just about moves e over LI.  Snow to start, then cold rain.  0 line at 850 over mass through most of the precip. DGEX brings it up the apps to right over nyc. CMC brings one low over or inside BM on the 14th, but cold enough for snow, then another more potent on the 15th, but much warmer, borderline rain.  12z UKMET slides low from TX at 120 to S of the BM on 144.  This one is up in the air, but GFS usually doesn't adjust east and any phasing probably just makes it stronger and further west.

Early Dec

12-9  Cold air hung tight today with high of 33.6. Did not get above freezing til noon or so.  Result was lots of ice, 2hr delay.  Barely any snow again, with light snow overnight melted, then refroze when frz rain came.  no real accum

12-8 -The 12-4 snow was a bust, as back end snows usually are.  NWS Albany had Litchfield Hills in 4-8 inches  - they got a dusting.  Most models had PA in at 6 inches, they got two.  Our area got some tiny flakes, but never got below freezing.  Pretty big bust from the models - basically the moisture came and went before the midlevel cold got in place.  So based on the current qpf outputs, 1-2 is a likely scenario, changing to freezing rain. Also think most of the precip will have fallen in sub32 temps, so only little rain/drizzle for Monday.

For tonites event, the amount of qpf is only .15 to .3 depending on the model, with only .15 of it falling while temps are conducive for snow.  It really shouldn't be a big deal - WWA in place though with 1-2 inches possible, and likely.  Sometimes WAA events (aka front end) result in heavier thumps of snow, but thats usually resulting from stubborn cold air.  However, this time there just isn't enough moisture. 

12-4 - no changes.  Slightly less chance on back end fri-sat morn, although its forecasted by nws as a possibility.  Sun-Mon looks more definitive, 1-3 likely at this point, before changing to freezing rain and rain

12-3 - Morning run still have a possible back end snows as a wave comes up the frontal boundary on the 7th.  Possibly our first measurable snow - an inch.  Euro has more front end on the 9th - 3-6 inches, while the GFS has 1-3 inches.  Still need to watch for freezing rain on the ninth.  GFS also has back end snows on the 10th after frontal passage, which while it looks good on the maps, it usually doesn't pan out to more than snow showers.

12-2 - nothing happening until perhaps the 7th or 9th.  Marginal, low yield, precip after cold front on the 7th.  Front end, low yield snow on the 9th (watch for freezing rain that day)

11-30 - Morning run. Only Euro Ens have any precip hitting the area.  The rest all go offshore.  Inverted trough over the cape. NAM is out to 84 and is the closest.

No interesting weather in next two weeks per Euro ens and GFS.  The teleconnections from this morning are +NAO, +AO, -PNA.  This should result in warmer quicker patterns.

11-28
Morning run - GFS has inverted trough on the first - interesting.  Euro, JMA have a storm brushing the east coast, affecting mostly the cape and Maine on the 4th.  UKMET is stronger and stacked, negative along the coast on the 4th  GFS is ots on that one, by a lot. So there is some activity in the next 10 days, but nothing major (over 3 inches) at this point.

11-27
Models have been on and off over the last few days around the 3-5th range.

Currently, the Euro has a weak storm coming up the coast and intensifying once NE of us.  UKMET is similar, though the afternoon run is outside the BM.  CMC has shortwave coming through and deepening a bit too offshore for us.  GFS 0z run has a weak storm on the 2nd over us, with another stronger storm sliding off the southern coast on the 4th. 12z run has the first low a bit more offshore, the second one far out at sea.  Euro's output had 1-2 inches of snow. GFS has the same, despite the offshore development

Late November issues

11-27 - no updates needed since 11-24 as nothing changed. GFS capitulated on the  11-24 afternoon run.  Low came right over DXR at 994mb.  It was amoebalike in that it was consolidated, then stretched, a second low did form, briefly. The winds didn't amount to much at the house, although were in the 40's along the coast.  Temp peaked at 60 (62 at DXR) at 6am, fell throughout the day (40 as of 3pm).  Rain amounts were over 3.5" as of noon, but there was still a lot of rain coming through.  Radar showed w nj changing to snow.  GFS 1, Euro 1

11-24
Morning - Euro goes over or just to west of NYC.  CMC well west of the area.  Both would have 850 temps near 10C.  GFS is still out of sorts.  It still has a slow southern stream, almost cut off, though it drops the northern stream coming through now with snow.  Instead its now onto the storm coming up the coast, just offshore, but still holds back energy for a second low to go ots.    GFS Track looks possible now, brings snow per below, but with still little support, hard to go with it.  Lots of rain, 3-4 inches on euro.  NAM brings stretched low up the coast, consolidates

11-23
Morning - GFS 0z run goes OTS, but does leave behind some snow for us.  Euro puts a weaker system right over us resulting in rain, and a little snow.  Canadian puts 996 low right over us.   JMA runs right over us.  GFS 6z still way OTS with little if any precip. So its the Euro/CMC/JMA/GFS Ens/UKMET vs the GFS operational!  Looking like a mostly rain event with some snow mixed.  Possible 1" accums show on most maps.
Afternoon - no changes

11-22
Afternoon - GFS is out to sea (OTS).  No precip.  Not good.
GFS Ensembles bring classic noreaster.  Perhaps a bit too close to the coast.  Argues the operational may not be correct. 
Euro - looks like yesterday afternoon - stretched out along the coast, two waves. Mix of rain/snow.  The printout of 850 temps is quite warm though, mostly rain.
CMC - further west than before, actually goes to our west.


Oy


Morning - GFS, CMC, Euro and JMA all have storm on Wed.  0z/6z GFS currently the furthest EAST, brings a mix of rain and snow for NW NJ, Orange, Putnam, N Fairfield, Litchfield Cty - with most being the furthest N or W.  The amounts range from 3-9 inches.  GFS, I think because it deepens the storm later, is warmer aloft and at the surface, which is not common when its the furthest east.
Euro brings storm inside of benchmark which usually means rain for most of the area.  However, since it deepens the storm so much, it draws in the cold air aloft, keeps the surface near freezing, and puts out 6-9 inches for the areas mentioned above, with some changeover to all snow for most other areas, and accumulating an inch or two
CMC phases a little later, inside the benchmark, bringing cold air in at the end.
JMA phases over VT, its the furthest west, with mostly all rain for the area.
Precip ranges from 1.2 to 2 inches - well needed.
Too close to call - climatology says mix, mostly rain except for Catskills, Poconos, Berkshires.  But the situation is so borderline that shifts of 50 miles in the track or 5mb in strength make the difference between all snow and all rain for DXR.  I would be confident in having a lousy Wednesday though.
Below are the positions from the Euro, GFS and Canadian - typically the result from these positions is rain with snow far inland.  

Euro - GFS - CMC

Euro snow

11-21
Morning - Euro has storm, rather stretched out along coast. No snow. An inch to two inches, NW to SE of rain. Cold air after may turn lingering precip to snow. GFS has some light snow on Tuesday, but much colder Wed and shoves storm out to see off NC.
Afternoon - GFS ditches the snow on Tuesday, stretches out a storm on Wed - Thurs, but does so more at a 45 degree angle off NC/SC. So still OTS. Euro consolidates the storm a little more than on the 0z run, but takes it directly up the coast over us, with over 2 inches of needed rain. The difference between the 850 temps from the GFS to the Euro is about 20 degrees - they are really that far apart now. Euro has a little snow on the back end. Throw the CMC into the mix, which looks closer to the euro, but holds off the coast and brings in the cold air, which means a snowier solution, but less overall precip. 11-20
Afternoon - 12z models including CMC now go out to sea.  Euro has some snow from the clipper, but not much.  Printout for Euro didn't match the graphic - printout had .5 inches of liquid mostly above freezing.  Graphic had 3 inches of snow, tues nite into wed.  850 temps and thickness are a tad too high. Continue to monitor.

Morning - GFS loses the cutoff, moves to Euro solution.  There is a high chance of a noreaster, not too strong on these runs, on the Wednesday before Thanksgiving, followed by a bust of cold air.  At this point, it does not look like the cold air in front of the storm will remain in place, so that the immediate tri state is mostly rain, but there could be front end and back end snow.  GFS even has snow on the ground.  EURO puts 1-3 down for the N&W subs, but plasters Upstate NY/VT with over 12 inches.

Euro has been on a cut off low dropping out of Canada, with air cold enough to possibly bring snow.  (see bottom of winter outlook) for a few days now.

GFS is kinda on board, different surface and upper air, but check out the snow totals and locations from the 0z and 6z runs.  CMC has a big high in place that day, but a disturbance brings a line of snow a few days earlier.

Winter outlook

Slow fade into winter....  October ended a little above normal, but dry - only 6% of monthly precip.  November looks above normal, not dramatically.  My initial thoughts were our first snow around the 24th of November, with first snowfall over an inch in mid December.  Consensus of sources are showing warm to start, cold to end with near normal snowfall.  I wouldn't be surprised going with only an inch of snow until January, perhaps late January.   This is similar to  2011-2012 when aside from the late Oct storm, we only had 13" of snow from Nov-Mar.  Our first snowfall over an inch came in late Jan that year. 

Supporting no winter for now, is the strong positive AO, positive NAO and what is going to a strong negative PNA - this combination should bring mild weather, with a lack of big storms, although impulses may bring rain from time to time. 

Also favoring a storm pattern to the great lakes, putting us in warm sectors often, with quicker shots of cold after fronts.  Looking at a SE ridge that doesn't want to budge in the short term (through Nov and likely into DEC).   Some talk of a sudden stratopheric warming event is out there, which typically flips patterns, but I'm skeptical that it happens, and if it does, they are hinting at Dec, which may not be that cold to start anyway. 

I'm going with within .5 degrees of normal, probably warmer, dry, with under 30 inches of snow, mostly in late Jan/Feb/Mar.  Hope I'm wrong.


 There is no change indicated on the long range models. Actually, there is a tropical storm hitting us on the GFS on the 20th.  Euro ens control disagrees, although it does have a strong southerly flow bringing tropicalish air in.

Halloween

Expecting relatively mild temps, perhaps some showers, tropical like conditions for the evening with increasing winds overnight.  NWS has wind watch for the eastern sections, but I'm concerned with our area as well.  All models have LLJ winds over 70kts at 5k feet with some winds over 50kts at 2500 ft as well.  These areas are more focused on the western portions than east.  Winds die down later on the first.

Nov 1 morning - clouds moving by very fast, breezy as winds are not making it to the surface yet.  Comments by Upton.

75 TO 85 KT LLJ AT 3000 FEET REACHES THE REGION AHEAD OF THE BAND
OF LOW TOPPED CONVECTION...AT LEAST PER THE 06Z RAP. BASED ON
WHAT`S HAPPENING OUT WEST...STABILITY IS FORTUNATELY PREVENTING
THE LLJ FROM REACHING THE SURFACE. BASED ON THE RAP
SOUNDINGS...THIS SHOULD BE THE CASE HERE TOO.

IT`S NOT UNTIL THE LOW TOPPED CONVECTION REACHES THE REGION THAT
MOMENTUM TRANSFERRED TO THE SURFACE IS OCCURRING. THERE IS STILL
A SIGNIFICANT LLJ THAT WINDS SHOULD APPROACH 50 KT. SINCE
CONFIDENCE FOR EXCEEDING 50 KT IS NOT HIGH ENOUGH...WILL KEEP US
AT WIND ADVISORY LEVELS. ALSO...GRID FORECAST IS NOT ACCOUNTING
FOR THE PEAK GUSTS.

WILL NEED TO WATCH THIS DEVELOPING SITUATION CLOSELY THE NEXT 6
HOURS. THERE IS POTENTIAL HERE FOR A SIGNIFICANT WIND EVENT. SPC
HAS BEEN ISSUING WATCHES FOR THIS OUT WEST AND SINCE THIS IS CONVECTIVE
     NWS WILL USE CONVECTIVE PRODUCTS (I.E. SVR) EVEN THOUGH THERE
IS NO THUNDER.

First frost

10/24/13
Patchy frost with temps in mid 30's this morn and yesterday morning.  Expecting killing frost overnight.

10/26/13 - NWS ends the growing season. Temps under freezing for a few hours, but most plants survive.

April Showers, not.

April showers bring May flowers and Mayflowers bring pilgrams

In Danbury, we are well below temp wise and critically low, for May flowers, in precip.    Normal high and low for the end of the month is 67/44  Below that is the outlook for rain over the next 10 days.  Less than .01"

May Day

4/21
Hoping this is the last post for the winter season.  Blocking pattern sets up in a week and systems are slow to move out, plus a shot of cold air will enter Canada and slide down around the end of the month.  This picture from the gfs is the temp at 850 and precip.  Keep in mind, for now, that the precip is falling during the day which on May first, would be 99% impossible to accumulate.  But, not sure what may fall either the night before or after. 

Fun to watch - not likely at all to happen. 6zGFS 4-21

March 18-19

3-19 -Low came up through the lakes, but the "warm" front did come up front loaded and we had 5" of snow before it drizzled and briefly showered rain at 32 degrees.  Temp stayed below freezing for just about all the precip, but there was not a lot of ice.

3/16
Models back and forth on this at first, settled for a storm through the lakes.  Euro/NAM /CMC showing front end snow, a few inches Monday night.  Euro has trended cold and is way different than GFS. Euro then GFS  - Euro much colder for now, almost a major snow storm.  GFS even has a few inches though. NAM Compromises.  My guess now is 2-4 inches front loaded, turning to rain.

3/7 - been watching the inverted trough coming off the coastal. Its snowed here since about 1am, with a coating to wake up to as it cooled to freezing near dawn, but now its not accumulating as temps are 34-35 and sun is making it through clouds from time to time.

12z runs
GFS = .6 with surface temps 32-34
Euro = .72 with sf temps 30-33
Nam -= 1.04 with temps 28-33

Presidents day

This is going to sound crazy, but the GFS, UKMET, GEM (canadian), CMC, and Nogaps all have a very serious storm over presidents day weekend.  DGEX and Euro have nothing.  GFS 6z run had a 956 Low over New England. Here are the pix - I'm sticking with the Euro.

Valentines Day

Still a potential for some snow as a storm system goes to our south. Its on all models, and can adjust north during the next day's run, but even if it did, just a few inches for here.  More down south though.

Feb 8-9

Feb 7th

Models vary from a foot on the GFS to 40+ on the NAM.  All have sub 980 low tracking near bm, some inside, some over.  Looking at 18", possibly over by a lot.  But after 18" doesn't really matter.

Danbury
GFS = 1.09 QPF with temps between -1.0 and + 0.2 at 850 for the bulk of precip. 4-8 inches of snow.
Euro = 2.2 QPF with max 850 temp at -3C. 18-24 inches of snow.
NAM = qpf .56 with 850 temps ranging from +.8 to -8.6 with surface temps below 0c the entire event.   3-6 inches of snow

Oddly, Groton's GFS 850 temps are lower the whole time.  Here are the snow maps - note NAM actually has over 70 inches for parts of SE Mass and RI.

Nam has trended towards phasing the system, but does it later than GFS and Euro.  GFS is moving in the direction of the Euro.  So there still can be movement of the heavier precip west (or east, I prefer west based on current trends).  The catch is does that mean more rain.

For places south of Rt 80, this is mostly a rain event, with some change to snow at the end (as it currently stands)

Feb 5th
12z GFS caves to Euro idea of phasing a northern stream system and southern stream system in our area on Friday into Saturday.  There is no blocking so the storm won't last very long, but the Euro is concerning.  It shows a 972mb low over the benchmark, which usually results in a blizzard for the areas NW of NYC, and potentially NYC and LI too.  Euro qpf for danbury is currently 1.53 with temps below 0 at 850 for the duration.  Boston, however, gets clobbered with over 3" of liquid precip and temps just at 0 or below for the duration. Translation - 3 feet.

1/25-26 event

I've been watching this one for a week now and its gone from blizzard to flizzard. The odd thing is that its a clipper (some call it a Miller B) which slides south of NYC, and should result in a 2-4 inch snow at minimum for CT.  However, it fizzles out and reforms (hence the Miller B nature) but too far offshore for anything more than an inch.  There should be high snow ratios though as the air is perfect temp for the highest ratio.  Still wondering if we can get 4+ out of this - there is no model supporting more than a dusting to an inch, but it still seems too low.

Light snow event tonite

Looking for some snow, 2-4 inches, perhaps more.  This is a front loaded snow fall and will probably turn to rain or freezing rain, but only after most of the precip has fallen.  Typically, these overperform model guidance, so while .25 is the precip amount predicted, it may result in 4 inches of snow.
