SYNOPSIS
Strong high pressure building in today will remain over the region into Saturday. The high will give way to an approaching warm front Saturday night. The front will move into the area on Sunday and may stall over Connecticut and Long Island early next week as weak high pressure noses down the New England coast.
A cold front will approach on Tuesday and move through Tuesday night. Another cold front may approach on Wednesday.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Northern stream shortwave pivots through northern New England today, with Canadian high pressure building in from the northwest through tonight, This will have an unseasonably cool airmass advecting into the region through the remainder of the day.
Light NE flow will continue to give way to inland moving seabreeze development.

Despite sunny skies, temperatures will top out around 10 degrees below normal, generally lower to mid 50s.

SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/
With the strong Canadian air mass settling over the region tonight, with near calm to light winds, and clear skies, temperatures will remain 5 to 10 degrees below seasonal normals.
Freezing temperatures are expected across the interior zones.
With the aforementioned conditions have a little more confidence that freezing conditions will occur tonight, and have issued a freeze watch for late tonight into early Friday morning for portions of northeastern New Jersey, into portions of the Lower Hudson Valley, and across interior southern Connecticut, and coastal New London.

The high remains over the region Friday and Friday night with some modification to the air mass as temperatures remain around 5 degrees below normal.

LONG TERM /SATURDAY THROUGH THURSDAY/
Model guidance still forecasts an omega block over the eastern CONUS, with its western leg over the central states and multiple shortwaves lifting NE through the Plains states and upper Great Lakes, its eastern leg over the Canadian Maritimes and adjacent Atlantic, and an upper ridge over the East. The first of the shortwaves lifting through the Plains and Great Lakes will send a warm front toward the area Sat night with some showers that should then move into the area on Sunday, then stall as the eastern leg of the block over the Atlantic strengthens, with low pressure well out to sea and high pressure nosing down the New England coast in the mid level confluence in its wake. NBM captures the details well and was used through the period.

After a cool Saturday with highs in the upper 50s/lower 60s, a warmup should begin on Sunday especially for the NYC metro area, lower Hudson Valley, and NE NJ. Mon should be the warmest of these days, with highs in the lower 80s from NYC north/west, and into the 70s most elsewhere except for ern Long Island and the SE CT coast, where highs should remain in the 60s. Temps on Tue are uncertain and could be a few degrees cooler than fcst if the western Atlantic low and maritime high pressure in its wake exert more influence.

The omega block should start to break down on Tue, with the upper ridge weakening and a cold front approaching from the west, bringing the chance for showers and tstms. The front will pass through Tue night, and could be followed by another cold front on Wed.

AVIATION /18Z THURSDAY THROUGH TUESDAY/
Strong high pressure will build in through the TAF period.

VFR. SSE winds this afternoon at 10 kt or less will become light and variable overnight. Winds will then return out of the SE late Friday morning into Friday afternoon.
