...UPDATE TO AVIATION...

.SHORT TERM...(Today and tonight)
Issued at 355 AM CDT Tue Aug 22 2017

A cold front was pushing south across western Kansas at 0830z, with
some stratus clouds developing in its wake. Low clouds will likely
be found across much of the area for a few hours this morning before
clearing out late morning or midday. The northeast winds will top
out around 20 mph most locations as well, mainly in the late morning
time frame when pressure gradient will be strongest. Deep layer
subsidence will continue to work in from the north, and this will
push any forcing for ascent along the frontal zone down into the
Texas Panhandle and western Oklahoma. As such, have removed any
remaining POPs along the OK border for today. Temperatures are
expected to top out in the lower to mid 80s...except upper 80s in
the Red Hills. Tonight, with the fresh airmass in place,
temperatures are expected to bottom out in the upper 50s.. perhaps
mid 50s up at Hays and Wakeeney.

.LONG TERM...(Wednesday through Monday)
Issued at 355 AM CDT Tue Aug 22 2017

A dry weather pattern, with surface high pressure encompassing the
Eastern Plains and Mississippi Valley, will continue through
Thursday. After that, winds will become southeasterly in the lower
troposphere, bringing low level moisture back north. A weak westerly
flow pattern across the Rockies in the mid levels will help develop
at least a weak leeside trough, and the convergence tied to this
would enhance potential for thunderstorm development late Thursday
into Thursday Night.  This fairly cool (by August standards) and
moist low level upslope pattern is expected to continue through the
weekend with the upper flow pattern becoming more west-northwesterly
aloft. This is a favorable wind direction in the middle troposphere
for MCS activity across eastern Colorado into western Kansas. There
is no sign of persistent heat building back in, with the upper level
high redeveloping well west across the Great Basin toward the end of
the forecast period.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 603 AM CDT Tue Aug 22 2017

A narrow corridor of low level stratus will spread southward across
southwest Kansas through daybreak resulting in IFR cigs in the vicinity
of KGCK, KLBL, and KDDC. VFR conditions will return to all TAF sites
by mid to late morning and prevail through late this evening. Northeast
winds 10 to 20kt will persist across western Kansas through tonight
in wake of a weak cold front moving southward across the region this
morning.
