.DISCUSSION...
Issued at 1257 AM CDT Mon Aug 3 2026

Pattern remains status quo for a good part of the week with
mid/upper ridging situated across the Desert Southwest into Texas,
troffiness in the SE states, and ridging in the Atlantic. Locally,
drier air & subsidence should be fairly dominate and keep things 
mostly dry through the midweek period (though an isolated late day
shower can't totally be ruled out with the seabreeze). 

Thursday and into the weekend, PW's trend upward and closer to the
2" range. And, depending on your model of choice, maybe a few 
weak inverted H5 waves tracking wwd across the nrn Gulf Coast toward
TX. Either should allow for slightly better diurnally driven rain
chances and coverage (perhaps 30-40%). 47

.AVIATION...
(12Z TAF Issuance)
Issued at 507 AM CDT Mon Aug 3 2026

Light and variable winds will persist through most of the morning
before becoming southerly to southeasterly in the afternoon hours.
Terminals closer to the coast will start out with light south-
southwesterly winds before transitioning to southeasterly winds
around 10 kt this afternoon. Cannot rule out intermittent periods
of patchy fog over the next few hours this morning in LBX/SGR. 
Isolated SH/TS possible this afternoon around the Houston metro 
terminals between 20Z-01Z, but the potential is too low to include
it in any of the TAFs. Brief periods of patchy fog will be 
possible again early Tuesday morning.
