Very interesting day today for the northeast as slightly warmer SW flow is overtaking the region.   These days are often tricky because decoupling will keep the winds off the surface.   Our forecast mentioned that the winds will be a bit fragile and recommended northern facing beaches over southern as the winds onset.   However, check out what happened at Kalmus.  kal graph

Notice this zone of green that comes off the bluffs on Martha’s Vineyard.  This is something we see often on Long Island Sound as the bluffs and relief of Long Island lift the winds off of the Sound.   Something to this theory?    Here is the regional snapshot:

Is the wind going to come back?  I hope so!
