AREA FORECAST DISCUSSION...UPDATED
National Weather Service Jackson KY
750 AM EST Thu Feb 16 2023
.UPDATE...
Issued at 750 AM EST THU FEB 16 2023
The continued trend for some of the heavier rains to fall to the
north per radar trends and the CAMs consensus - with some gaudy
QPF from various runs of the HRRR - have prompted an expansion of
the Flash Flood Watch further north in eastern Kentucky. Have
updated the grids primarily to fine tune the PoPs and beef up QPF
north. Did also add in the latest obs and trends for the T/Td
grids. These updates have been sent to the NDFD and web servers
along with a freshened set of zones, HWO, FFA, and SAFs.

.SHORT TERM...(Today through Friday)
Issued at 535 AM EST THU FEB 16 2023
Key Messages:
1. Widespread showers, with times of thunderstorms and heavy
rain, can be expected through tonight.
2. Severe thunderstorm potential primarily for our western and
northern areas (northwest of Sandy Hook to Williamsburg) this
evening and into the night with damaging wind gusts the main
threat.
3. Turning colder late tonight after the front moves through with
snow showers through the day on Friday. Any light accumulations
will be limited to the higher terrain near the Virginia border.
09Z sfc analysis shows a developing area of low pressure just west
of the state riding northeast along a well defined boundary off
to the northwest of Kentucky. This features a tightening pressure
gradient supporting south winds of near 10 mph through eastern
Kentucky this morning. It is these winds, and additional ones
aloft, that are pushing higher PW air into the state along with
sustaining a warm air mass. As a result, within the WAA sector of
the main low, bands of showers and embedded thunderstorm are
moving slowly northeast through the area bringing decent QPF to
the area with the pockets of heavier rain occurring this morning.
In this environment, temperatures and dewpoints are fairly
uniform in the unseasonably mild and wet mid to upper 50s. While
sfc based instability is still paltry over the area predawn, some
limited elevated CAPE has been able to keep thunder going amid the
main shower clusters.
The models are in surprisingly good agreement aloft through the
period especially considering the dynamic pattern affecting the
region. They all depict deep layer southwest flow tightening up
today and into tonight as an opening up, once deep, 5h wave lifts
from the Central Plains to the Great Lakes by Friday morning.
This process manages to maintain the amplified pattern aloft
through Friday by having a significant portion of the trough
holding back through the Southern Plains even as its main core
stretches off to the east. This will bring some stark height falls
to eastern Kentucky tonight and Friday with a quite healthy band
of energy sweeping across the JKL CWA while the 5h trough axis
does not pass until near 00Z Saturday. The small model spread
supports using the NBM guidance as the starting point with most
adjustments centered on severe parameters and QPF - particularly
in the near term.
Sensible weather will feature four seasons of very active weather
through the end of the work week. The ongoing heavy rain and
thunderstorm threat early this morning will set the stage for
potential flooding from training cells through the morning -
capped off by a band of additional heavy rain moving through this
evening and tonight. The main concern for this situation is the
establishment of prolonged bands of training convection this
morning saturating the soils and producing excess runoff where
they set up. This remains a confidence challenge as the hi-res
models have had a hard time pinpointing a consistent location for
the band of highest QPF. Latest HRRR runs continue to shift to the
northwest which could spare the Cumberland and parts of the
Kentucky basins the worst runoff, but also target the Red and
Licking basins. Up to 6 inches of its model QPF heightens
concern for these locations. There is still enough model and
ensemble support for heavy rain through the southeast 2/3rds of
the area, and in conjunction with WPC's excessive rain outlook, to
prompt the issuance of a Flood Watch into early Friday morning.
However, near term convective and CAM trends may necessitate a
shift in the Flood Watch and best QPF more northwest. This
situation will be monitored through the morning for updates to
headlines and forecast specifics as needed.
The next weather challenge will come from the anticipated pre-
frontal thunderstorm line moving west to east later this evening
with a strong potential for severe weather developing in central
Kentucky and progressing east toward the JKL CWA. This line of
storms will probably weaken as it runs out of the best
instability when moving into eastern Kentucky. However strong to
damaging convective winds gusts will be the main threat from these
storms when they get here, though some large hail or an isolated
tornado cannot be ruled out should the convective line stay robust
as it arrives. We continue to message the Enhanced and Slight
Risk for severe weather this evening and into the night for this
front.
The front clears the area by dawn Friday with strong CAA in its
wake and that will support ample lingering pcpn transitioning to
snow showers from west to east as the column cools. Look for the
upslope winds post frontal to support snow showers through most of
the day over the area, though warm ground and road temperatures
will minimize and zero out any impacts - outside of maybe the
highest peaks near the Virgnia border. A return to winter weather
will be a stark contrast as highs today in the mid and upper 60s
are replaced by afternoon readings in the mid 30s for most on
Friday.
Did not adjust temperatures much from the NBM through the period
but did favor the PoPs and QPF from the CAMs today and tonight -
exceeding them on Friday to better capture the upslope snow
showers.
.LONG TERM...(Friday night through Wednesday)
Issued at 426 AM EST THU FEB 16 2023
The 16/00z model suite shows a positively-tilted 500H trough
extending from Southern Quebec to the Tennessee Valley at the start
of the period. Surface low pressure is centered over Nova Scotia
while Canadian high pressure resides from the eastern Texas to the
Lower Ohio Valley.
Any lingering upslope snow showers and flurries over the higher
elevations near the VA border will come to an end Friday
evening/night as that high pressure builds east and the cyclonic
flow around the departing low ceases. Expect skies to gradually
clear, leading to a rather cold night after clouds suppress the
temperatures on Friday. The fair weather will persist on Saturday
as well, though high clouds become more prevalent late in the day.
Thicker mid to high cloud cover will attend a passing upper level
disturbance Saturday night. After one more day of quiet weather
on Sunday, the new work week will feature an unsettled quasi-
zonal flow pattern with a series of low pressure systems riding
along a lingering baroclinic zone over the Ohio Valley.
Temperatures will start the period near to slightly below normal but
will quickly recover back to above normal. The coldest night, Friday
night, is forecast to have low temperatures ranging in the upper
teens through the colder hollows up to the middle 20s over the
thermal belt ridges. From there, high temperatures warm into the
mid 40s to lower 50s on Saturday, mainly into the 50s on Sunday
and Monday, and then mostly 60s on Tuesday and Wednesday. Low
temperatures moderate into the mid 20s to mid 30s on Saturday
night and then range mainly in the 30s and 40s through Tuesday
night.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
ISSUED AT 725 AM EST THU FEB 16 2023
Showers and times of thunderstorms will keep conditions mainly in
the MVFR category for VIS and often CIGs, but with times of VFR
possible, mainly in the afternoon. Times of IFR or even lower will
be possible, especially during any passing thunderstorm. There is
also a chance that storms could approach severe limits later in
the day, with the best chance occurring along and west of a line
from KSYM to KLOZ. After that line goes through CIGs will fall to
MVFR and possible IFR into Friday morning. South to southwest
winds of 5 to 10 kts currently will increase to 10 to 20 kts
during the day, with gusts of 20 to 30 kts possible, especially if
any more substantial breaks in the convection occurs.

...Thunderstorms With Strong Winds and Heavy Rain Today Into
Tonight...
A low pressure system passing just to our north will bring a cold
front through the region later tonight. Along and ahead of the
front, showers and thunderstorms will affect us today into
tonight. Heavy rainfall is likely for a portion of the area,
leading to significant rises on streams. Some of the thunderstorms
could also bring strong or damaging winds on today or this
evening. However, the greatest threat for severe thunderstorms
is over central and northern Kentucky.
