.SHORT TERM...(Today through Wednesday)
Issued at 534 AM EST TUE DEC 2 2025

Winter weather event is ongoing. An upper level trough extends
from the Great Lakes to the souther plains early this morning,
with an embedded shortwave over the lower Ohio Valley, while
surface low pressure near the FL panhandle is transitioning to
development near the Carolinas coast. Overrunning moisture from
the south along with lift from the trough/shortwave is responsible
for the ongoing precipitation. Brightbanding is observed on radar
early this morning over the northern portion of the forecast area
indicating the change from rain to snow. The switch will continue
to make its way southeast as colder air arrives, especially aloft.
However, outside of our northern/northwestern counties the period
of any snow should be brief enough to not be a concern. Areas
around I-64 northward will likely see an inch or two, with amounts
tapering off to the southeast. The most significant precipitation
is expected to taper off from northwest to southeast this morning.
As deeper moisture aloft is lost, ice production in the clouds may
also be lost, which could result in a change to drizzle (or
freezing drizzle where temps remain below freezing). Even drizzle
will eventually taper off as moisture becomes more and more
shallow, with the last of it tapering off in southeast KY in the
afternoon or early evening.

High pressure will build in from the west tonight, but cold air
advection and upslope flow will persist as the high approaches
and will make it difficult for clouds to break up. Tentatively
have decreasing clouds forecast tonight into Wednesday, but
confidence in the timing is not very high.

.LONG TERM...(Wednesday night through Monday)
Issued at 521 AM EST TUE DEC 2 2025

At the onset of the long-term period, a 590-dm sub-tropical high
resides over the Gulf, centered over Cuba. A sub-500-dm low
remains over the Hudson Bay area, with a trailing cold front down
through Southeast Canada, The Great Lakes, and back through the
Ohio Valley. All-while a ridge of high pressure dominates the
Pacific, from Hawaii all the way up to the Yukon region. Models
and ensembles are in good agreement through Friday.

Wednesday night, increasing clouds can be expected across Eastern
Kentucky as the cold front from the Hudson Bay low traverses the
Ohio Valley with a slight chance of snow showers just north of
Fleming County. Temperatures overnight are expected to fall into the
low to mid 20s in hollows and sheltered valleys, while ridgetops
remain in the upper 20s to near 30. While this cold front passes to
the north, moisture gets pulled around the Gulf high into the
Lower Mississippi Valley. Frontogenesis is expected later
Thursday. Current models put a slug of rain across the Southeast
U.S. while Eastern Kentucky remains rather unscathed. There is a
period Thursday night where a slight chance of snow showers exists
with no major impacts expected.

Friday and beyond, model and ensemble spread increases considerably
with disagreement in timing and placement of systems. The ECMWF
lags the showers across the Southeast U.S. until Friday, and also
has showers further north across Eastern Kentucky. As a result
POPs fluctuate between 15-35% Friday through Monday next week. Of
those days, Saturday looks to have the best chance of being dry,
at least at current.

Below-normal temperatures look to continue through the week, with
highs generally in the upper 30s to mid 40s, with lows in the 20s to
low 30s. Thursday night looks to be the coldest of the long-term
with lows ranging from the mid-teens across the north, to mid 20s
across the south.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
ISSUED AT 1210 AM EST TUE DEC 2 2025

A mix of low end VFR and MVFR conditions were noted across
eastern Kentucky at 06Z issuance time. Precipitation has
overtaken the area during the late evening with mostly rain but
some freezing rain reported for a time just after onset before the
wetbulbs came up. Conditions will deteriorate to IFR or worse
into dawn with the sfc low moving east of the area and colder air
from the west cooling the column. Conditions then slowly improve
from northwest to southeast toward afternoon. Winds will be
variable through the period at 5 kts or less.
