Area Forecast Discussion
National Weather Service Wilmington OH
119 PM EDT Fri Jun 27 2025
.SYNOPSIS...
A slow-moving and weak frontal system will be a focus for scattered
showers and thunderstorms to develop this weekend. Warm and humid
conditions will continue through Sunday, with few areas having heat
indices topping out in the mid 90s. A slightly stronger cold front
will bring more numerous storms on Monday, then temperatures will
return to near or just slightly above normal values beginning
Tuesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Storms that develop this afternoon look to be similar to yesterday's
heavy rainfall rates. However, they should have some movement to
them where they don't park themselves over any one particular place
for any significant length of time. Pwat values remain constant over
the region with 1.83" at 12Z this morning and 00Z last night, a
relatively insignificant decrease from yesterday's 12Z reading of
1.89". Steering h5 winds over the region were 5kt or less, leading to
the slow movement. Today there should be about 20kt in the north,
15kt in the south. Hardly worth the mention, but will be supported by
the same direction of h8 winds that will exhibit 15-20kt in the
north, 10-15kt in the south. Storms should exhibit at least some
slow movement to the ne to where the rainfall rates of 2"+/hr don't
park for an hour over any location. Prev discussion:
Mid-level ridging will continue to be in place across the middle Ohio
Valley today. With diurnal instability, there will still be
scattered convection developing from midday into the afternoon
hours... especially southeast of I-71. With high temperatures in the
upper 80s to lower 90s and dewpoints well into the 70s, the heat
index will once again reach around 100 degrees.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Few changes were made to the NBM initialization this afternoon. Pops
through Sat were set at a minimum of 20% as there were a lot of areas
NBM was showing without any rain chances. Don't know how it could do
this given primarily airmass thunderstorms today and tonight. Capped
pops through this time at 50% as well, which trimmed down a little
bit of initialization pops that were likely. Convection through this
time should be scattered, even as a weakening front enters from the
north on Saturday. This front looks to become more diffuse as the day
wears on. Although convection should occur along/near boundary,
indications are that pre-frontal shallow convection may occur in the
latter part of the morning.
For Saturday, the front will likely stall across central Ohio. This
will lead to the most instability being found across our southern and
eastern counties. Therefore, have focused thunderstorm development
southeast of I-71. There's a possibility that the bulk of precip
tomorrow will be showers with isolated thunder found along/s of the
Ohio River. With west-northwesterly surface flow developing and
some weak cool air advection, highs will be limited to the middle to
upper 80s.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Hot and humid conditions remain in place through Monday ahead of an
approaching cold front. On Sunday, rain chances once again develop in
the afternoon although probabilities and coverage should be
relatively minimal compared to Monday or some of the past few days.
On Monday, PWATs increase to 2+ inches which is extremely high for
the Ohio Valley ahead of the aforementioned cold front. Storm
chances accompany the high PWATs during peak heating in the
afternoon/evening. Any storms that do develop will likely produce
torrential rainfall rates which could lead to isolated flood
concerns. The good news on Monday is that southwesterly flow
increases which may help storms move at around 15-20 mph. Quicker
storm motions should limit most flood concerns to areas where
training/repeated rounds occur.
The cold front likely pushes through the area on Tuesday thereby
limiting the best chances for showers/storms to areas southeast of
the boundary. This leaves the most likely area for rain to be along
and southeast of I-71 during the day.
Wednesday and Thursday are likely to be dry across the area behind
the cold front as high pressure moves through. Temperatures are
forecast to be slightly below average to near average. Diurnal rain
chances may redevelop around Friday when southerly flow returns.
&&
.AVIATION /18Z FRIDAY THROUGH TUESDAY/...
Outside of scattered convection this afternoon that should be more
miss-than-hit for the terminals, VFR conditions are expected. While
the likelihood of a direct hit from a storm may be low, they will be
scattered about, creating wind shifts from outflows that will be
erratic and gusty. Am continuing the prob30 for this afternoon and
will try to amend quickly when development presents itself. Outflow
winds yesterday, while erratic, were on the order of 25-30kt at times
closer to the cells.
When development occurs, early amendments will probably change over
to a vcts versus prob30, as this would imply the storms affecting the
terminals even if further away than the 5-10 mile vicinity donuts
surrounding them.
Guidance is fairly pitiful, only bringing ci to the region for the
next 24-36 hours. Showers and a few thunderstorms found se of the
I-71 corridor beginning after noon will be significantly weaker than
storms these past few days. Thermodynamic profiles are notably shy
on instability with short range ensembles bring mucape maxima of
2000J/kg further to the se of the I-71 corridor and not affecting
terminals. Terminals along the corridor /everyone but KDAY/ are
topped off at ~1500J/kg at 18Z, decreasing for the remainder of the
afternoon.
OUTLOOK...Thunderstorms are possible through Monday, focused in the
afternoon and early evening.
