Area Forecast Discussion
National Weather Service Wilmington OH
1021 AM EST Tue Feb 11 2025
.SYNOPSIS...
Snow will overspread much of the region today with a southern
wave moving through. Another low pressure system quickly moves
in on Wednesday, ushering in mostly rainfall, but some freezing
rain will occur in our northwest counties. A brief dry period
will ensue through the end of the work week, but another low
pressure moves in on Saturday and will result in mostly rain
initially, followed by snow on the back end Saturday night into
Sunday.

.NEAR TERM /THROUGH TONIGHT/...
Update was focused on lowering the pops from Columbus southwest
to Cincy and then west along I-74. Models are all showing a
tight gradient here and the gradient is just northwest of the
advisory area, which comes in line with both the previous and
updated forecast. The reduction may have bled into the advisory
area but that does not change the amounts listed given the
southeastern edge was likely not adjusted by this.
This even tighter gradient in the forecast was mainly applied
through 21Z, as the retreat of the precip shield to the east
kicks in at this time. The threat for a wintery mix in the
warning area comes for a few hours mainly this evening, and
should not creep into the advisory area for any significant area
or time frame. The mix will also primarily be of the rain/snow
mix as surface temperatures right at the freezing mark should
not permit more than a light glaze later overnight, and only
expected in the far southeastern CWA. This ZR potential
encompasses a very small spatial area, primarily in KY, and is
centered an hour or two on either side of midnight. Prev
discussion:
A southern tracking wave will result in some wintry
precipitation across the ILN fa today. As the lower levels
continue to saturate this morning, the drier air as a result of
the easterly flow will eventually be overcome, leading to
accumulating snowfall. Snow accumulations will first begin
across northern KY, where the highest accumulations are
expected. Soundings continue to show ample lift/moisture
embedded within the DGZ, resulting in dendritic snowflakes that
are conducive to rapid accumulations. Again, this is primarily
favored along/south of the OH River. The greatest snow
accumulations will occur during the daytime hours and on
grassy/elevated surfaces. Marginal near-surface and pavement
temperatures should limit some of the accumulations on roadways,
especially any treated surfaces.
CAMs still show some inconsistencies on the northern extent of
snowfall today, but the I-71 corridor likely denotes the
northern/western extent of accumulations. The exception would be
near the Tristate as higher snow amounts are favored across our
southern counties.
Based on latest model guidance, no changes to the headlines are
being made. Snow amounts remain similar to previous forecasts.
&&
.SHORT TERM /WEDNESDAY/...
Snowfall will continue into the overnight hours, but the
intensity will quickly decrease after sunset. Thus,
accumulations will be limited tonight, although any snow that
does fall will stick to surfaces easier. Currently only have a
few tenths of snow accumulations in the grids, mainly SE of
I-71.
One important feature to monitor tonight is the potential for
some light freezing rain/drizzle to develop, especially
near/south of the OH River. Hi-res models continue to show the
potential for lingering precip/moisture in this area, and
bufkit soundings usher in a warm nose a few thousand ft AGL.
This would result in melting snowflakes, likely melting entirely
to liquid form. Sub-freezing surface temperatures will lead to
instant freeze on contact. While freezing rain is expected to
be patchy, this could lead to additional icy/slick spots tonight
into Wednesday morning.
WAA will ensue on Wednesday, which should help improve road
conditions as we progress into the afternoon hours. Some light
rain may scoot across our counties southeast of I-71 early in
the day, but pcpn is expected to be spotty until coverage
increases by the late afternoon/early evening. Temperatures
will continue to increase through the evening and the beginning
of Wednesday night ahead of an approaching surface low.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Widespread pcpn will continue into Wednesday night as the surface
low lifts northeast along the I-71 corridor. WAA ahead of the low
will lead to non-diurnal temperatures with rising temps across
about the southeast half of our area. As the low moves off to
the northeast, colder air will begin to advect into our area
behind it with temperatures dropping off from the northwest late.
Given the track of the low, temperatures across our far northwest
will likely remain near or just below freezing, so freezing rain
will remain possible into Wednesday evening for our far northwest
counties. Meanwhile, pcpn will taper off through the overnight
hours, but may go over to a brief period of light snow
across our northwest before ending.
Surface high pressure will push east across the Ohio Valley
Thursday into Friday. This will lead to mainly dry and seasonably
cool conditions. Will likely have some non-diurnal temperatures on
Thursday in the CAA, with afternoon temperatures ranging from
the upper 20s in the northwest to the mid 30s in the southeast.
Highs on Friday will range from the lower 30s in the north to the
upper 30s in the south.
A mid level trough will shift out of the Plains on Saturday to
the East Coast through Monday. Embedded mid level energy moving
through the trough will lead to a developing surface low pressure
system over the lower Mississippi Valley on Saturday with the low
then lifting east-northeast across the Tennessee Valley through the
day on Sunday. Ahead of this, pcpn will develop across our area
Friday night and become widespread Saturday and Saturday night
before beginning to decrease in coverage through the day on Sunday.
Both the GFS and ECMWF Ensembles have trended somewhat colder with
this system, so will trend temperatures down somewhat from the NBM
through the weekend. With this in mind will allow for more of a mix
of snow across at least out north Friday night through Saturday,
with pcpn then changing over to all snow Saturday night into
Sunday. In this scenario, a few inches of snow would be possible
Saturday night into Sunday, especially across our north. Will keep
highs on Saturday mostly in the 40s. CAA will then develop Saturday
into Sunday with much colder air filtering into the region through
early next week. Highs by Monday will range from the upper teens in
the north to the upper 20s in the south.
&&
.AVIATION /15Z TUESDAY THROUGH SATURDAY/...
TAFs not quite as pessimistic for today as previously forecast,
especially for our northern terminals. Snow is still expected
across KCVG/KLUK and KILN, but for the rest, have removed a
mention of snow given the low chance of reaching that far north.
Still cannot rule out a few flakes at KDAY, but did not feel it
was worth mentioning in the latest forecast.
MVFR CIGs still appear likely for our southern terminals, but
now with a slightly later onset time. IFR CIGs now less likely,
so have removed that mention early in the taf period.
Snow will begin to taper off this evening, but there is a chance
for patchy freezing drizzle to develop tonight, which would
mainly impact KCVG/KLUK. Additionally, have continued to
mention CIG reductions tonight as low level moisture persists,
and the next low pressure center will already begin to move in.
Further categorical reductions will be possible with this next
system - already have IFR CIGs mentioned at KCVG/KLUK for early
Wednesday morning.
OUTLOOK...MVFR to IFR conditions are expected from Wednesday
afternoon through Thursday, and again on Saturday.
