.Short Term...(This evening through Saturday)
Issued at 311 PM EST Fri Jan 1 2021

...Gusty Winds & A Few Strong Showers or Storms Possible...

The warm sector has quickly become established over most of our
region at this hour as KY Mesonet obs show low 70s readings across
the southern half of central KY at this hour. The 60 degree line has
almost made it to the Ohio River, and will continue advecting
northward on the aid of good heating, and with some advection ahead
of a surface low currently over west central KY.

We've seen some deeper mixing where clouds have cleared out in the
this dry slot, and even a couple of gusts just over 40 mph. Will go
ahead with a short Wind Advisory in anticipation of a few more 40+
gusts popping up. We do have another couple/few hours of the 40-50
knot low level jet core over our warm sector, and sounding show low
level thermal profiles capable of tapping into that higher momentum
air aloft, so can't rule out the stronger gusts developing.

Speaking of stronger gusts, we also have the threat of some low
topped convection for the afternoon and early evening. Have started
to see a broken line of showers develop across our NW CWA, just
ahead of a convergent surface feature that will push into our north
central CWA over the next 1 to 2 hours. As this occurs, there should
be better alignment of enough low level convergence and the
instability axis that is now ranging around 500-750 J/KG of near
surface based CAPE across south central KY. The HRRR has suggested
now for a couple of consistent runs (along with the 12z NAM 12
solution) that scattered to numerous low topped showers or storms
will develop across north central KY and then move toward the
Bluegrass region into the early evening hours. If these storms do
get a bit better organized, then isolated instances of stronger
gusty winds will be on the table. At this point, think the threat
for any tornadic activity would be a bit lower right ahead of the
front as low level hodographs are a little less favorable, but still
a few rotating storms would be possible in this shear environment.
Again, all of this is conditional upon the convection getting going
better as the HRRR would suggest.

A look at soundings does show a limiting factor to the depth of the
convective potential around 700mb, which will likely be a limiting
factor for deeper convection and the ultimate reason why there isn't
more of a severe risk depicted by SPC. Nevertheless, higher momentum
air aloft could be brought down with any more robust updrafts.

.Long Term...(Saturday night through Friday)
Issued at 201 PM EST Fri Jan 1 2021

Widespread precipitation will move into the region tomorrow night as
a negatively tilted shortwave trough swings into the lower Ohio
Valley. Temperature profiles generally support an all liquid
scenario across most of central KY, but some diagnostic and ensemble
model members highlight temperatures getting cold enough to support
snow across southern IN. In the colder model scenarios, the vast
majority of snowfall accumulations are minor (<1"). The trough
should lift northeast of the region by Sunday morning, though
lingering low level moisture could result in periods of drizzle and
clouds through a good portion of the day.

Most of early next week will feature dry weather as an upper level
ridge advances from the west and keeps the region confined to dry NW
flow aloft. It's not until late Wednesday into Thursday that the
next chance of precipitation arrives ahead of an upper level low.
Long range guidance varies on the timing and evolution of this low
over our region, which isn't too surprising considering it's +150
hours out. Given the variability, will keep the PoP chances low, but
think at some point in the late-week period several locations
will have a decent shot at observing precipitation.

.Aviation...(18Z TAF Issuance)
Issued at 1246 PM EST Fri Jan 1 2021

A potent storm system will move out of the mid Mississippi River
Valley and up into the Great Lakes by Saturday morning. This is
lifting a warm front across the area now, followed by a quick cold
frontal passage this evening, and then post frontal low ceilings
(IFR likely) and perhaps some lingering drizzle through the end of
the cycle.

Currently, the more widespread rain has lifted north of the TAF
sites, and now comes the low confidence period this afternoon ahead
of the front where some additional scattered showers and perhaps an
isolated t-storm could develop. The most likely sites to possibly
get hit by a stronger shower or storm would be SDF or LEX and have
tried to subtly hint at this in the TAF, although confidence remains
quite low in development potential. Otherwise, the current IFR
ceilings at SDF/HNB/LEX should gradually give way to some brief
improved conditions before ceilings drop back into lower MVFR ranges
and possibly into IFR toward dawn on Saturday. Some drizzle may
accompany that as well. Winds will also gust into the 25 to 35 mph
range with direction veering from SE to S to SW through the period
as the front passes. Also started the northern sites off with a
couple hours of continued to LLWS before the main core works
eastward and diminishes.

...Gusty Winds Ahead Of A Cold Front This Afternoon...

Gusty south and southwest winds are expected this afternoon and
into the early evening ahead of an approaching cold front. Peak
gusts are expected to mostly range in the 30 to 35 mph range, but
a few gusts up around 40 mph cannot be ruled out.

There is also potential for a few stronger showers or an isolated
storm to bring some gusty winds. If this occurs, some gusts over
40 mph cannot be ruled out. Therefore, use caution this afternoon
and evening, especially if you plan to be outside enjoying the
rest of this mild holiday.
