...New AVIATION...

.SHORT TERM...
(This evening through Thursday)
Issued at 207 PM CDT Wed Oct 27 2021

Much drier, and breezy conditions have moved in today behind the
line of strong to severe thunderstorms swept through the entire area
last night. Winds have been sustained near 30 mph at times, along
with gusts over 40 mph out of the northwest across the area.
Temperatures have also been much cooler with highs so far only in
the upper 60s to lower 70s.

For tonight, winds will diminish during the evening hours to 10 to
15 mph out of the northwest. Clear skies, dry air, and diminishing
winds will allow temperatures to fall into the 40s across much of
the area, with some locations in the lower 50s. On Thursday, winds
will again pick up out of the northwest, especially across our
eastern counties, where a stronger surface pressure gradient will
exist. These northwest winds will also be aided by 850mb winds of 35
to 40 knots that will be able to mix to the surface at times by late
morning after surface heating gets going. Will go ahead and issue
another Wind Advisory on Thursday for our northern and eastern
counties where winds will be strongest.

.LONG TERM...
(Thursday night through next Wednesday)
Issued at 207 PM CDT Wed Oct 27 2021

Below normal temperatures will continue on Friday, with highs in the
low to mid 70s. Overnight lows will be in the low to mid 40s.
Slightly warmer temperatures are forecast this weekend, with highs
in the upper 70s to lower 80s.

An upper level trough is forecast to swing across the northern Great
Plains Sunday, sending a cold front through West Central Texas late
Sunday into Monday. The GFS is indicating a few showers along the
front, but for now have kept PoPs below 15 percent. Slightly cooler
temperatures are forecast behind the front with highs in the low to
mid 70s. There continue to be some differences with respect to the
synoptic pattern for the middle to latter part of next week, between
the ECMWF and GFS. The overall consensus is that a broad upper level
trough will be located across the central CONUS, with a strong cold
front pushing into the area on Wednesday. Overall, a wetter/cooler
pattern is looking more likely for the middle to latter part of the
week, and the details will become more clear as we get closer to the
event.

.AVIATION...
(00Z TAFS)
Issued at 644 PM CDT Wed Oct 27 2021

VFR conditions will prevail across the terminals the next 24
hours. Northwest winds will diminish to 10 knots or less by 02Z,
then increase and become gusty again by mid to late morning.
Expect wind gusts between 25 and 35 knots, highest at KABI and
KSJT. Could see some LLWS develop overnight but it appears
marginal at this time, so will not mention but re-evaluate for
the 06Z forecast.
