6-21 LP did form, but it looks like its also with an upper low. NWS has it at 1008mb as of this morning, but it looked better last night. Its currently between a ridge and approaching cold front.
Meanwhile TD 4 did actually form and made it to TS Danielle, the earliest 4th storm in history. It moved WSW over Mexico. Danielle peaked at 45mph and 1007mb. 12 inches of rain was expected.
6-17 - still there, a little weaker on the euro today. The GFS has a lot of potential in days 8-15including Gulf Action near NOLA.
6-16 Different position, still out there though. Low heads off the coast, probably becomes warm core as its cut off from baroclinic forces, then heads briefly NW before heading out to sea - per Euro. Here are peak gusts. Surface, 925 and 850 are warmer around the storm, indicating warm core as well.
So this is early, 10 days out. Pattern favors in close development and cold fronts are likely to spin up storms. So I think there will be at least eyes on this area through the third week in June. Its track is up for grabs - it could just spin up and head east.
0z GFS also has the initial LP descend into the Mid Atlantic, where it reforms off the coast and heads east.
