Flash Flood Warning 14, NWS Wilmington, OH

Area Forecast Discussion
National Weather Service Wilmington OH
116 PM EDT Wed May 27 2026

.WHAT HAS CHANGED...
Dropped the Flood Watch across our northern areas.

&&

.KEY MESSAGES...
1) Periods of showers and embedded thunderstorms will occur into the
early evening. Locally heavy rainfall will be possible.

2) An extended period of dry weather will occur from Thursday into at
least the early next week with temperatures generally within a few
degrees of normal.

&&

.DISCUSSION...
KEY MESSAGE 1)
Mid level circulation evident on radar moving slowly east across
southern Illinois/Indiana attm while a warm front is extending east
from it across southern Ohio.

A fair amount of sun in the warm sector to the south of the front
has allowed for our southern areas to destabilize this afternoon with
ML Capes running in the 1000-1500 J/KG range. Most of the stronger activity
is currently right along the frontal boundary. Expect the
shower/thunderstorm activity to continue to work its way east-
southeast through early evening with some additional scattered
development possible in the warm sector this afternoon. Locally
heavy rainfall will remain the main threat, although a lower end
severe risk will be possible across southern portions of our area
into early evening. The main threat will be damaging winds. However,
a few rotating storms will also be possible, leading to a low end
tornado threat. The best chance for this would be across our
southeast.

KEY MESSAGE 2)
High pressure will remain in place across the region through the
weekend, providing for dry and seasonable conditions.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Showers and embedded thunderstorms will continue to sag slowly east-
southeast across the region through early evening. Any thunder
chances should remain south of the I-70 TAF sites, mainly affecting
the southern TAF sites. MVFR to occasional IFR cigs and vsbys will
be possible into early evening before clouds begin to scatter out.
High pressure will build into the region tonight into Thursday. With
mostly clear skies and light winds some MVFR to locally IFR br will
be possible later tonight into early Thursday.

OUTLOOK...No significant weather expected.
