...New AVIATION...

.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 250 PM CDT Mon Jul 14 2025

An MCV continues to spin near the Mexican border this afternoon.
There are isolated showers and thunderstorms from the Rio Grande
to Hwy 281. Convection is generally producing moderate rain now.
PW in the airmass is still abnormally high, and any stronger
updrafts could produce locally heavy rain. These systems tend to
be more active overnight when the low level jet strengthens. We
are seeing the diurnal reduction which should continue after
sunset. This MCV will still be in the region tonight and
interact with our very moist airmass. Showers and thunderstorms
will continue tonight and Tuesday with locally heavy rain
possible. Additional rainfall of 1-3 inches with isolated totals
up to 6 inches is possible. We are going to extend the Flood
Watch until Tuesday morning and expand it to include all of the
I-35 Corridor. Models move the MCV away from our CWA Tuesday
evening bringing an end to rain chances.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 250 PM CDT Mon Jul 14 2025

A drier weather pattern will move in mid to late next week with
the upper ridge nudging westward into the area from the Gulf.
Most areas should remain rain free outside of perhaps a stray
to isolated shower or storm with the onshore flow and/or sea
breeze. Best chance of this would be Friday in the coastal
plains. With the decrease in overall cloud cover and slightly
stronger 500 mb heights, expect for a slight uptick in the
daytime highs through the second half of the week and into the
weekend.

Right now, rain chances remain out of the forecast, but we`ll also
monitor for the possible development of a tropical disturbance or
inverted trough following behind in the wake of the upper level
ridging that nudges to our area. This feature may slowly advance
westward along/parallel to the northern Gulf coast towards and
through the weekend. We continue to monitor to see if this feature
gains additional model support within the coming forecast
cycles.

.AVIATION...
(00Z TAFS)
Issued at 628 PM CDT Mon Jul 14 2025

SHRA with OCNL TS are currently along the I-35 corridor and have
mentioned VCSH until 01Z there. Expect another round of SHRA/TSRA
west of I-35 tonight into Tuesday. Have maintained VCSH mention at
KDRT with no mention at the I-35 sites. There is a potential that
later forecasts to include prevailing should timing and impacts
become more certain. Otherwise, VFR conditions turn MVFR overnight,
then return to VFR midday on Tuesday. S to SE winds prevail with some
gustiness during the daytime into evening hours, as well as near
SHRA/TSRA.
