...New SHORT TERM, LONG TERM...

.SHORT TERM...
(This afternoon through Thursday Night)
Issued at 210 PM CDT Wed Oct 12 2022

Convection is ongoing early this afternoon in the eastern half and
a line moving into the northwest ahead of a cold front. CAMs have
struggled to decide on a secondary line of storms closer to the
front this evening that may bring additional chances for strong to
severe storms, especially in the southwest. But, instability will
begin to weaken this evening, and the primary severe threat
remains this afternoon through mid evening or so. Current data
shows MLCAPE values around 500 to 1000 J/kg, and deep layer shear
40 to 50 knots. The HRRR and NAM suggest some bowing segments will
be possible along the line of storms, and would support more of a
damaging wind gust threat. Winds are the primary threat with any
strong to severe storms that develop, but hail and even an
isolated tornado or two can not be ruled out, especially later in
the afternoon to early evening when low level wind shear is
expected to increase with the approaching trough and cold front.
Showers and storms should move off to the east after midnight with
the severe threat likely coming to an end in the late evening.

After the front moves through tonight, dry air will continue to
advect into the mid state during the day. Northwest winds around
10 to 15 mph and gusts to 25 mph will help low level mixing, and
may bring drier air to the surface as well. This will increase the
fire weather threat in the afternoon with min RH values in the 20
to 25 percent range across the area.

&&

.LONG TERM...
(Friday through next Wednesday)
Issued at 210 PM CDT Wed Oct 12 2022

Dry conditions will continue for the remainder of the work week,
but a Midwest trough looks to bring another cold front through
this weekend, with additional chances for showers and
thunderstorms Saturday afternoon through the day Sunday. Likely
will not be a washout, but models are showing slightly different
solutions on timing for the weekend. The coldest air so far this
season will follow the front early next week, with highs on
Tuesday only in the 50s and lows in the 30s Tuesday morning. Lows
in the 20s will be possible Wednesday morning in low lying areas
and on the Plateau. Models do show 850mb temps around -2C to -6C
Tuesday morning and Wednesday morning, so freezing temps look
likely both of those mornings.

&&

.AVIATION...
(18Z TAFS)
Issued at 1227 PM CDT Wed Oct 12 2022

Showers and thunderstorms will push through the mid-state early in
the TAF period, with MVFR VIS and CIGS expected for all sites.
Will have to watch for strong/variable gusty winds right as the
line of storms moves through, as well as possible brief IFR
conditions. After about 09Z conditions should improve from west to
east with clear skies after 15Z.
