.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 150 PM CDT Tue Jul 8 2025

An upper level trough over the Gulf is approaching the TX coast.
This feature is generating showers and thunderstorms over the
Coastal Plains. Showers and thunderstorms will continue to
spread toward the I-35 Corridor and may reach the eastern Hill
Country by late this afternoon. Rainfall rates have been
moderate and this should continue through the afternoon.
Convection should dissipate rapidly after sunset. Temperatures
will drop to near normal lows overnight. The upper level trough
will continue to move into TX Wednesday bringing another round
of showers and thunderstorms across the Coastal Plains and I-35
to the Hill Country. The airmass over the region will continue
to slowly dry and rainfall should be mostly moderate. High
temperatures Wednesday will be about the same as today.
Convection should die off quickly again with the loss of daytime
heating. It looks like there will be less cloudiness Wednesday
night allowing temperatures to drop a couple of degrees lower
than tonight.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 150 PM CDT Tue Jul 8 2025

Thursday the upper trough will move away from our CWA and the
subtropical ridge will strengthen bringing an end to convection
for most of the area Thursday and Friday. There will be slight
chances for showers over the Coastal Plains along the seabreeze.
With no rain and less cloudiness temperatures will rise a few
degrees getting back to near normal. The subtropical ridge will
weaken again over the weekend allowing for another chance for
showers and thunderstorms. Convection will be possible both
afternoons across our entire CWA. Chances will be highest over
the east where moisture will be deepest. Slight chances for rain
will continue Monday and Tuesday during the day. Temperatures
will rise a little more getting a bit above normal.

.AVIATION...
(00Z TAFS)
Issued at 654 PM CDT Tue Jul 8 2025

Early evening convection is focusing away from the I-35 Corridor and
should be gone by dusk for the rest of the area. Less coverage of
convection is expected for Wednesday, so will not plan on any Prob30
groups for now. Scattered areas of low cigs are expected again
tonight, but with the south breeze falling below 5 knots at times,
there will be more periods of SCT coverage with VFR skies mixed in.
