.SHORT TERM...(This evening through Thursday night)
Issued at 346 PM EDT WED APR 24 2024

A very quiet short term period is in store again. Surface high
pressure centered over eastern Ontario late today will slowly
pass by to our northeast, reaching New England late Thursday
night, providing us with continued fair weather in a cool and dry
air mass. Aloft, ridging over the high plains and troughing over
the eastern CONUS will gradually shift east, with the ridging
nearing our area late Thursday night.

As heating is lost this evening, our fair weather cu will dry up
and leave clear skies to last into Thursday. Slightly drier
low levels combined with warming above 850mb should pretty much
prevent cu on Thursday. However, high clouds will likely spill
through the upper level ridge into our area late Thursday and
especially Thursday night in advance of our next weather system.

Good radiating conditions each night will allow for chilly low
temperatures, especially in valleys. Increasing clouds could
eventually hinder radiating on Thursday night, but probably not
until very late. The largest ridge/valley differences are
forecast on Thursday night when a return of weak warm air
advection will help to hold ridges warmer. Lows should be cold
enough to allow for some frost in the coldest valleys each night,
especially our northern counties. However, it does not look to be
widespread so as to warrant an advisory.

.LONG TERM...(Friday through Wednesday)
Issued at 346 PM EDT WED APR 24 2024

An updated long term discussion will be sent shortly.
