Area Forecast Discussion
National Weather Service Wilmington OH
325 AM EDT Sat Mar 15 2025
.SYNOPSIS...
Occasional showers and thunderstorms are expected today into Sunday
as a strong low pressure system moves through the Great Lakes
region. High pressure will then build into the Ohio Valley through
mid week, bringing an extended period of dry weather.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A broken line of thunderstorms with embedded supercells is moving
east northeast across southern Illinois and western Kentucky at this
time. These storms will continue to work their way toward our area
through the pre-dawn hours. Thermodynamically, the airmass across
our area is not as favorable with surface dewpoints still in the 40s,
so do expect to see an overall weakening trend in the intensity and
coverage of these storms as they approach. However, given the
impressive wind fields, it will be tough to rule out a few strong to
severe storms, mainly across our far west. While it would be tough
to rule out a brief tornado, the primary threat would be damaging
winds, especially given the potential for some enhancement due to
evaporative cooling. As the pcpn moves across the rest of our area,
expect to see a continued weakening trend through mid morning. We
then may end up with a lull in pcpn from late morning into early
afternoon.
Mid level short wave energy moving through the base of the upper
level trough will help spin up a secondary wave/low pressure system
across the Tennessee valley this afternoon. With an associated
strengthening 70-80 knot 850 mb jet nosing up into the mid Ohio
Valley by late afternoon, expect widespread showers and
embedded thunderstorms to spread back in from the south through mid
to late afternoon. There remains some uncertainty as to how much
surface based instability will be present by this time and this may
end up limiting the overall severe threat. Again though, given the
strong wind fields, it will be tough to rule out a few strong to
severe storms later this afternoon into early evening, with
damaging wind the main threat.
No changes planned to the Wind Advisory attm.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
Widespread showers and embedded thunderstorms will continue into
tonight along the nose of the strong low level jet, before beginning
to shift slowly east through the overnight hours. With PWs pushing
up to around 1.5 inches, heavy rain will be possible. There remains
a fair amount of variance with the models in where the swath of
heaviest rain will line up and just how far north it will make it.
Have therefore decided to build a little uncertainty into the Flood
Watch and extend it a bit farther north for tonight.
Shower activity will linger into the day on Sunday as the upper
level trough axis shifts east across our area.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
High pressure skirts by south of the area Sunday night through
Monday. Cool and dry conditions are expected. Surface high pressure
shifts east by midweek thereby causing southerly flow to redevelop
over area by Monday night. Southerly flow increases through
Wednesday when a strong low pressure system moves into the Great
Lakes. Precipitation chances return ahead of a cold front associated
with the low into Wednesday night. FROPA is currently forecast to
occur around the Wednesday night/Thursday timeframe. Precipitation
may linger a bit behind the front when gusty northwesterly winds
move in behind the front. Cooler conditions return behind the front
for the end of the week.
&&
.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
Line of thunderstorms currently moving across southern Illinois and
far western Kentucky will continue to move east through the pre dawn
hours. This line should weaken and begin to fall apart as it moves
into a less favorable environment across our area later this
morning. Nonetheless, will likely see a period of showers and some
embedded thunderstorms in the 10Z-14Z time frame. A tightening
pressure gradient will lead to increasing southerly winds today with
some gusts to around 40 knots possible.
Once the morning activity dissipates, we may end up in an overall
lull in pcpn from late morning into early afternoon. A secondary low
pressure system will then lift north across the mid Ohio Valley
later this afternoon into tonight. This will lead to widespread
showers and embedded thunderstorms, with MVFR cigs and vsbys
developing. Windy conditions will persist into tonight with wind
gusts of 30 to 35 knots remaining possible.
OUTLOOK...MVFR conditions will linger into Sunday.
