Area Forecast Discussion
National Weather Service Wilmington OH
644 AM EDT Wed Jun 10 2026
.WHAT HAS CHANGED...
Heat advisory issued for west central Ohio. Flood watch is cancelled.
&&
.KEY MESSAGES...
1) Potential for additional flooding has ended.
2) Hot and humid conditions will occur today and Thursday.
3) A cold front will move through the area on Friday with a second
cold front moving through on Sunday. It will become cooler and less
humid early next week.
&&
.DISCUSSION...
KEY MESSAGE 1)
It has become apparent that there will be no additional organized
development of showers and thunderstorms across the southwestern part
of the forecast area, although cannot rule out a shower or two still.
Thus was able to cancel the flood watch early.
KEY MESSAGE 2) Humid air mass will remain in place. There will be a
decrease in cloud cover this afternoon which will allow temperatures
to rise into the upper 80s. A pocket of slightly warmer 850 mb
temperatures is forecast to move across west central Ohio today, so
highs could get to 90 there. Temperatures are forecast to be very
similar on Thursday. The heat index will range from 95 to 100 both
days. In coordination with surrounding offices have issued a heat
advisory for west central Ohio for today where there is a somewhat
better probability of reaching a heat index of 100.
KEY MESSAGE 3)
A cold front will approach the region late Thursday night and may
even get into northwest counties before daybreak Friday. Convection
that will occur along the front well west of the area during the
afternoon and evening will most likely have weakened substantially if
not completely dissipated by the time the front arrives in the
forecast area. However, it is not completely out of the realm of
possibilities that a few stronger storms gets this far east late
Thursday night, and if that would happen then there could be a strong
to damaging wind gust.
With daytime heating on Friday, there will be convective
redevelopment along the front. Whether that occurs from central Ohio
into northeast Kentucky or whether that occurs after the front is
east of the forecast area is still a bit uncertain. Convection is
expected to become robust, so there could be some potential for
severe storms.
In the wake of the front, a less humid air mass will spread into the
area for Saturday. But moisture will quickly return Saturday night.
Another cold front will move through on Sunday with more showers and
storms. It will then become cooler and less humid for early next week.
&&
.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
MVFR to IFR ceilings will occur across the region to start the
period. The clouds will lift and scatter before 18Z. VFR will prevail
from there on out with few to scattered cumulus.
OUTLOOK... Thunderstorms possible Sunday.
