AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
228 AM EDT Fri May 31 2024

.SYNOPSIS...
High pressure of Canadian origin will bring dry and cool conditions
through Friday. An unsettled pattern is expected from late Saturday
through early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Tranquil weather conditions overnight across the Ohio Valley
thanks to surface high pressure. Not expecting as much river fog
formation tonight given the drier air. Seasonably cool overnight
lows are forecast, with 40s expected across the entire CWA.

&&

.SHORT TERM /SATURDAY/...
Surface high pressure will be overhead on Friday into Friday
evening. Light southeasterly winds persist under mostly sunny skies.
Forecast highs are in the middle to upper 70s.

Surface high pressure starts shifting east during the second half of
Friday night while an upper level shortwave approaches from the
west. Increasing clouds are expected through the night thanks to
upper level forcing increasing. Showers/storms are not expected
until after well daybreak on Saturday. Forecast lows drop into the
50s early Friday night before stabilizing during the second half of
the overnight.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Deamplifying short wave will move through the region during the
early part of the period. An associated weak cold front will cross
the area Saturday night, although there are some timing differences
depending on how strong a wave might develop along this front.
Showers and some thunderstorms will spread into the area, especially
during the afternoon and continue through Saturday night. This
activity is forecast to move off to the east by Sunday morning.

High pressure will build in behind the front and result in a dry
period from Sunday afternoon through most of Monday. A nebulous
pattern ensues until a stronger trough develops into the central
part of the continent. Weak forcing out ahead of this trough could
result in some showers and thunderstorms but the better chances will
come towards mid week with the stronger forcing, although there are
the usual timing differences with the potential approach of the next
cold front late in the period.

Temperatures will be within a few degrees of normal over the weekend
with reading then warming up next week with highs in the lower to
mid 80s and lows in the lower to mid 60s.

&&

.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
Surface high pressure of Canadian origin will provide dry
weather and mainly the VFR conditions to the area. The
exception is KLUK where some river valley fog is possible this
morning. Drier air tonight should limit this vsby reduction, so
have limited any mention to MVFR restrictions.

Some high level clouds attempt to move in from the west today,
but drier air will limit coverage. Surface winds will generally
be out of the ENE, but may still vary quite a bit. Light Winds
near or below 7 kts expected through the period.

OUTLOOK...Thunderstorms will be possible late Saturday through
Tuesday.
