328 PM CDT Fri Oct 15 2021

.SHORT TERM...(Tonight through Sunday night)
Issued at 328 PM CDT Fri Oct 15 2021

Scattered thunderstorms are expected to continue to develop and
stream eastward across west Kentucky into the early evening.
Effective shear of 40-50kts along with 500-1000J/kg of MLCAPE are
apparently sufficient to support a few mini-supercells with a
damaging wind and tornado threat.

The HRRR continues to develop convection from central Arkansas
northeastward into the Purchase Area around 00Z right as the real
cold front arrives there. The 12Z HREF hit that area with its best
updraft helicities, which would support more rotating storms with
a damaging wind and tornado threat. The bottom line is that we
will not likely not be able to cancel any portion of the watch
before its expiration at 8 PM.

While all of this is going on, forcing with the approaching upper
trough will result in widespread showers and possibly a few
rumbles of thunder over most of the region into the evening hours.
The precipitation is expected to move out of the area by around
06Z and skies over the entire should be clear by 12Z Saturday.

The other story is the gusty northwest winds expected this
evening behind the cold front. The stronger gradient should begin
to impact the northwest portions of the area around 23Z and the
spread eastward over the next few hours. There will be a 3 to 4
hour period of 20-30kts gusts with sustained winds 15-20kts. It
will not be a pleasant evening for outdoor activities, especially
in the east.

Surface high pressure will settle to our southwest late Saturday
and the pressure gradient will be weak enough that much of the
area will see calm winds Saturday night. With dewpoints expected
to be in the upper 30s areawide, some patchy frost cannot be ruled
out, especially in the sheltered valleys in southeast Missouri.
Our forecast lows may not be cool enough.

Saturday's highs will be in the middle to upper 60s or several
degrees below normal despite full sunshine. The airmass will
modify a bit Sunday and that will lead to a slight warming trend
in both highs and lows.

.LONG TERM...(Monday through Friday)
Issued at 328 PM CDT Fri Oct 15 2021

By Mon, the PAH forecast area will be under ridging aloft and high
surface pressure, providing mostly clear and dry conditions. The
surface high will continue to move slowly eastward with time as the
ridge is slowly replaced by cyclonic flow to the southeast of a
Midwest cyclone. The medium range models continued to indicate
limited moisture return by Wed ahead of a cold front due to
southwesterly to west-southwesterly low level winds. However, there
should be enough moisture/lift for some scattered to isolated
development of shower activity mainly Wed night with the slightest
chance of a lightning strike. The National Blend of Models kept
chance PoPs mainly in the eastern half of the region for Thu
afternoon as the cold front continues to move through west-to-east.
Thu night and Fri look dry and a bit cooler.

For most of the extended forecast period, expect somewhat above
average temps for this time of year, with highs in the 70s except
upper 60s Fri (Day 7). Lows will be in the 40s and 50s.

.AVIATION...
Issued at 1254 PM CDT Fri Oct 15 2021

Scattered showers and isolated thunderstorms are expected to
increase in coverage over the region through the afternoon. TSRA
will likely be limited to the KPAH TAF near the cold front around
00Z. A brief period of IFR or MVFR ceilings are expected just
behind the front, with rapid clearing expected late evening into
the overnight hours. Northwest winds will increase significantly
behind the front with sustained winds 15-20kts and gusts 20-30kts.
Winds will diminish a bit overnight and then pick back up with
mixing Saturday morning. Gusts Saturday will be up to around
20kts.
