DEC-MAR Summary


 
4-1 Summarizing the winter - it was cold! Nearly 5 below normal. Below is the climate data map from
Accupro, for DEC-MAR. 6 days reached 0 or below. 10 was the lowest high. We have not broken 60 degrees in 2014, but reached 58 in January, and 59 in March.  This is unusual, but 2013 had a similar lack of warmth.
We also ended up with about 75% of the precip we normally do, with Feb being slightly over 100%. March was very dry, until the last three days when half the months rain fell. The airport recorded only
a trace of snow for March. The 62" of snow recorded at the airport is half the record amount, but 50%
greater than average.

These stats, particularly the cold, are remarkable since the teleconnections did not cooperate, or add up to this pattern. Nothing terribly cold on the AO, almost entirely positive NAO, and a PNA that split its time. EPO also was nothing steady

More possibilities...

4-1  No april fools.

NWS has snow in the forecast thurs night into friday.  Models don't really support this as a low cuts up to our west, tries to secondary, but its too warm by then.  They are focused on a piece of energy coming out ahead of that, but with 850s freezing line moving further north, can't see how we get snow.  Freezing rain, if surface temps warrant, but nothing to worry about.

4/8 to 4/10

CMC has snow, at least higher up.
Euro has a lesser system, borderline snow, but brings a big storm up at the end of the run
GFS has storm, but a bit warmer and stronger, shoots the low at hr 240 out to sea.

DGEX has storm at 980 moving right over NYC and bouncing east.  850's support start and end as snow.

More crazy snow maps

4-8 Today's 0z Euro snow map for 4-16.  emoticon roll eyes...  Something went wrong as 850's are above 0, thickness above 540, vertical velocities are barely supportive.  925's are below 0, so wondering if its picking up a sleet storm, but converting it to snow.... Temps are below freezing though.
