...New AVIATION...

.SHORT TERM...
(Today through Sunday)
Issued at 320 AM CDT Sat Sep 24 2022

This weekend, an inverted trough lingers from northeastern Mexico to
over southern into central Texas, an upper level trough deepens east
of the Rockies and an upper level ridge builds west of the Rockies.
A surface to lower level ridge drifts off to the east today, then a
cold front approaches our area late on Sunday. These features allow
lower to mid level moisture to deepen with PWs rising to above
seasonal normal levels over southeastern areas today and most areas
on Sunday. Daytime heating and the seabreeze should be able to
generate isolated showers and perhaps a thunderstorm or two in the
afternoon hours each day. The airmass will be similar to several
days ago when convection overperformed the models. Of note, a few of
the CAMs/Hi-res models show this potential. Have maintained slight
chances mainly near the Coastal Plains today and have introduced
slight chances most areas for Sunday. Above normal temperatures will
continue.

.LONG TERM...
(Sunday night through Friday)
Issued at 320 AM CDT Sat Sep 24 2022

A mid to upper level trough will dig down over the eastern half of
the country Sunday night and Monday and bring a cold front across
our CWA Monday. There won`t be much moisture with this front and we
have only slight chances for rain across the Rio Grande Plains Monday
afternoon. It will bring cooler, drier air. Models have trended a bit
warmer for high temperatures, but still show near normal highs. The
drier air behind the front will allow for greater diurnal spread of
temperatures with cool mornings and warm afternoons through the end
of the period. Low temperatures for the second half of the week will
be in the 50s and 60s.

.AVIATION...
(18Z TAFS)
Issued at 1127 AM CDT Sat Sep 24 2022

VFR conditions are currently prevailing across the region with sct
low clouds and VFR ceilings near the I35 sites. VFR should continue
to prevail this afternoon and evening with southerly wind speeds
around 10-13 knots. Can`t completely rule out a shower closer to the
terminals this afternoon, but chances are much too low to mention at
this time. SCT to BKN MVFR low clouds will be possible late tonight
for much of the area.
