&&
.NEAR TERM /THROUGH SUNDAY NIGHT/...
Rest of this afternoon expect mainly sunny skies to remain with
a light breeze from the W-NW. Winds will relax as the sun sets
around 615-630PM. Tonight, a weak warm front will be lifting NE
through the area as return S-SW flow develops with the high
departing to the east of Nova Scotia. Expecting clouds to
increase from SW to NE as seen on visible satellite this
afternoon in western New England. Intially, skies clear and
winds relaxing will allow for northern locations to quickly drop
back into the 40s and even some 30s. Most other locations
generally upper 40s to low 50s for temperatures tonight. S winds
generally less than 5mph but decoupling in those northern areas.
Expecting some patchy fog tonight but mainly in river valleys
and over lakes/ponds.
Tomorrow AM, cold front will approach from the NW and expecting
some isolated to scattered showers mainly across the north and
eastern areas. West-southwest winds tomorrow 10-15mph with
occasionally gusting up to 20mph. Temperatures will top out
around 70F across the north under partly sunny skies. Central
Highlands to Interior Downeast looking at upper 70s to around
80F. Mid 70s for the Downeast coast but 60s on the islands
thanks to the seabreeze off the waters. Winds will shift W-NW in
the late afternoon to early evening as the front shifts.
Tomorrow night the flow turns zonal at 500mb with a 591dam over
the Ohio River Valley. Surface high pressure drifts east into
New York state which brings back dry air in from Canada. Skies
will clear and temperatures fall back into the 40s north and
around 50F south.
&&
.SHORT TERM /MONDAY THROUGH TUESDAY/...
High pressure south of the area on Monday will bring a warm westerly
return flow across the area under a sunny sky. Highs will range from
near 70 north to the mid to upper 70s Downeast. A weak cold front
will approach from the north late in the day.
The cold front will cross the area Monday night. Strong subsidence
from a building ridge to the west and very little moisture along the
front will result in a dry frontal passage.
Strong high pressure will be over Hudson Bay Canada on Tuesday
supported by steep upper ridging building across Manitoba and
Ontario. This high will push cooler air south from far Eastern
Canada on Tuesday upon gusty northwesterly winds. Temperatures in
the north will only top out around 60 while Downeast has highs
closer to 70.
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
Tuesday night will be mostly clear, brisk and chilly as high
pressure continues to build down from central Canada. The northerly
gradient will likely remain strong enough to prevent the air from
decoupling. However, it will be cold enough for lows to drop to near
freezing in the northwest and the low 40s Downeast.
Wednesday will be the coolest day of the week as high pressure
continues to build down from central Canada and chilly air from
Eastern Canada crosses the region. Highs will be mainly in the 50s
across the area with a brisk north wind.
High pressure will become nearby to the west Wednesday night.
Northwestern areas may decouple with some of the coldest valleys
dropping into the 20s under a clear sky. Elsewhere, lows will be
mainly in the 30s.
Thursday will begin brisk and chilly. High pressure building to our
west will work with strong subsidence to boost temperatures to
around 60 under bright sunshine.
High pressure will sink south of the area Thursday night as a weak
westerly return flow comes in behind the high. This will bring
another cool night, but not was cold across the north as Wednesday
night with a clear sky expected.
A westerly return flow around high pressure will continue to usher
in milder air on Friday with highs under a sunny sky reaching the
mid to upper 60s. Some mid and high clouds may form over the north
late in the day as a warm front forms just to our north in the
circulation around the upper high.
