805 PM EDT TUE MAY 24 2016
A ridge of high pressure will build over the northeastern U.S.
bringing a noticeably warmer and more summer-like pattern with
showers and thunderstorms possible each afternoon and evening into
the first part of the holiday weekend. Slightly cooler weather
may arrive for Memorial Day.
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Light winds and clear skies should provide for another cool
overnight with lows mainly in the 50s and upper 40s in cooler
spots of the western mountains.
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Wednesday should be a near picture perfect summer day. Mostly
sunny skies, light winds, and temperatures mainly in the upper 70s
It will not be as cool overnight Wednesday into Thursday but
should still be comfortable. But the humid will be beginning it`s
.LONG TERM /THURSDAY THROUGH TUESDAY/...
The extended guidance continues to show a strong ridge over the
mid Atlantic and the Great Lakes region through the weekend. This
will bring the arrival of the first extended period of summer-
like temperatures and humidity.
By Thursday we will be embedded in a broad WSW flow aloft.
Slightly above normal PWATS support the idea that humidity will
become noticeable over most of the area for the first time this
warm season. It also means we will be susceptible to mainly
afternoon convection pretty much on a daily basis into the
weekend. However the strong ridge should provide enough subsidence
to keep any convection at bay Thursday and Friday. The GFS is
very aggressive poking the Bermuda ridge strongly up over the
eastern U.S. Saturday while the ECMWF is a little flatter. However
given the southerly flow of moisture, the warmer temperatures and
the possibility of a mid level trough advecting through, Saturday
should have a decent chance for some afternoon convection. The
trend is for the ridge to break down late in the weekend and for
cooler air to move into the region early next week. This could
bring temperatures to slightly below normal.
.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
-- Changed Discussion --High pressure aloft and at the surface building into the region
tonight into wednesday will bring minimal clouds and primarily VFR
