Area Forecast Discussion
National Weather Service Wilmington OH
138 AM EDT Fri Jul 4 2025

.SYNOPSIS...
High pressure will prevail into the weekend. A weak cold front will
drop into the area early next week.

&&

.NEAR TERM /THROUGH TODAY/...
Center of surface high will move across the area today. Mid level
heights will be rising. Few to scattered cumulus will develop in the
afternoon. Temperatures will be just slightly warmer than yesterday.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/...
Center of surface high will slide off to the east but dry airmass
associated with it will persist. Heights will rise just a bit more as
the mid level high extends a bit further northeast into the region.
There is a small chance (less than 20 percent) that convection that
may occur in northwest Ohio during peak heating on Friday drifts into
west central Ohio this evening before dissipating. The gradual
increase in temperatures will continue.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Upper level ridging keeps dry weather over the Ohio Valley through
Saturday night. On Sunday, upper level ridging flattens when a weak
surface cold front sags in from the north. The approaching front
will support a chance for showers and thunderstorms by the afternoon
hours. Forecast highs are in the lower 90s. Heat index values could
be approach 100 if conditions remain dry.

The washed out cold front reaches the area on Monday and meanders
through the middle of the week perhaps lifting north by late week.
This will allow for chances for showers and thunderstorms every day
especially each afternoon/evening. Forecast highs remain cooler than
the past week with temperatures peaking in the 80s in the absence of
persistent southerly flow.

&&

.AVIATION /05Z FRIDAY THROUGH TUESDAY/...
Surface high over the area will keep winds light. There are some
indications that MVFR visibilities may develop prior to 12Z at KLUK,
KILN, and KLCK. Any fog that does occur will dissipate by 13Z.
Otherwise, few to scattered cumulus will develop with heating and
then dissipate towards 00Z.

OUTLOOK...Thunderstorms are possible Monday and Tuesday.
