Area forecast discussion, Jul 21, 1:54 PM EDT, 1 hour 9 minutes before

Area Forecast Discussion
National Weather Service Wilmington OH
154 PM EDT Tue Jul 21 2026

.WHAT HAS CHANGED...
Flood Watch issued for this afternoon and evening across our
southeast.

&&

.KEY MESSAGES...
Key Message 1) Thunderstorms are expected through early evening,
with severe storms possible, as well as potential for flooding.

Key Message 2) Drier and cooler conditions expected through the rest
of the week.

&&

.DISCUSSION...
Key Message 1)

First round of storms have generally pushed through the region, with
increasing coverage of storms especially in the Tri State and central
Ohio areas at this time. This round has much with greater potential
for strong/severe storms largely through 22-00z. Keeping an eye on
singular/discrete cells and potential for rotation/a tornado or 2 is
possible. Damaging winds remain the main threat though.  Flood watch
was expanded just slightly north as PW values at/just above 2" are
yielding very efficient heavy rain in the thunderstorms this morning.
While overall storms should be progressive, repeated storms over the
same area has prompted the slightly expanded Flood Watch.

Regional atmosphere able to destabilize following morning convection
ahead of the main shortwave trough over the Great Lakes, with
mesoanalysis indicating the potential for SB CAPES recovering to 3000
J/Kg. With the main frontal boundary stretching from NW Ohio into
north Central Indiana, the severe threat is diminishing for the far NW
quadrant of our CWA. Best chance for convective development/severe
storms will be along and ahead of the pre frontal trough -
essentially along/south of I70, with the greatest potential in areas
near/south of the Ohio River and south central/central Ohio. The
main threat with the 50-60kts of bulk shear will be damaging winds,
and with 0-1km shear is 20-25kts in this area, a tornado or 2 can't
be ruled out. The main threat for discrete/rotating storms will be in
the early part of the storm event, largely before 21z, with the
potential for a QLCS continuing through the region - exiting by 00z.

Key Message 2)

High pressure will build into the region behind the front for mid
week. Calmer/drier/cooler weather is expected into the late week.
Temperatures will then begin to slowly moderate toward more
seasonable values as we head into the weekend.

&&

.AVIATION /18Z TUESDAY THROUGH SATURDAY/...
In anticipation of additional convective development, with remaining
uncertainty for especially KDAY/KCMH/KLCK, have tweaked potential
timing of the thunderstorms slightly earlier, with TEMPO
thunderstorms largely from 18-22z, though isolated thunderstorms
between 22-00z didn't warrant a tempo or prob at this time.

Gusty winds in excess of 40 knots and very heavy rainfall will be
possible with thunderstorms through 22-00z, and as the frontal
boundary sinks through the area between 21-02z, winds will shift to NW
and gust to near 25kts and then diminish shortly after FROPA.

Drier air moving in behind the front will also lead to a decreasing
cloud trend overnight into Wednesday. Expecting possible MVFR to even
IFR at KLUK.

OUTLOOK...No significant weather expected.
