.SYNOPSIS...
A weak upper level disturbance over the area slips southward on
today. Weak high pressure builds through the weekend. Cold
front approaches by mid next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 130 AM Thursday...

As upper level low heads east, may still get a pop up shower
across the mountains and southern coal fields this afternoon and
evening. Otherwise looking at a dry day with plenty of
sunshine. Afternoon highs will generally be 5-10 degrees above
normal. River valley fog expected again tonight under mostly
clear skies.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
As of 215 AM Thursday...

High pressure remains in control with mainly dry conditions,
and above normal temperatures through the weekend. An isolated
shower or storm could develop along the eastern mountains due to
diurnal heating and orographic effect. River valley fog
expected in mornings.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
As of 215 PM Wednesday...

High pressure will remain in control at least through mid week with
dry conditions. On Thursday, a cold front reaches southeast Ohio

this point, any QPF in the long term period looks to remain
minimal.
