high pressure will keep dry conditions across the region through
the weekend.


Near term /until 6 am Wednesday morning/...
clear skies will continue through the overnight hours with light
to calm winds across the area. Temperatures will drop off quickly
this evening. Went on the cool side or slightly cooler than
guidance for low temperatures overnight with good radiational
cooling setup. Kept low temperatures in the 40s however cannot
rule out an isolated overnight low in the 30s. Dry airmass is in
place however some River Valley fog will still be possible


Short term /6 am Wednesday morning through Thursday night/...
high pressure will allow for dry conditions across the region
through the short term. High temperatures are expected to be in
the 70s with low temperatures in the 40s and 50s. Not expecting
much in the way of cloud cover through this time period. Clear
skies will give way to a few middle and high clouds later in the
short term.


Long term /Friday through Tuesday/...
a ridge of high pressure will linger at the surface and aloft Friday
through Sunday. This pattern will allow clear...dry weather to
persist during the first half of the long term.

The high pressure system will start to move east on Monday...while
an upper trough and weak surface low develop to the west. The low is
expected to lift across the area on Tuesday. Moisture...isentropic
lift...and instability will increase on a southeast flow ahead of
the low...bringing a chance for showers and thunderstorms starting
Monday afternoon in southwest counties...spreading across the area

slipping a bit into the middle and upper 70s Tuesday under clouds and
precipitation. Normal highs will be in the lower to middle 70s.
