DISCUSSION

Issued at 223 PM CDT Thu Sep 10 2026

Mid-level troughing between ridging east and west of the area will remain over the area through the weekend. For now, the trough will remain located generally over the water, and will keep the best rain chances there and up into the Victoria Crossroads region. We will see a general lowering of deep moisture tomorrow from levels that are currently well above normal (2.1-2.25"). The pocket of highest moisture will drift northeastward, but remain close enough to keep moderate rain chances in the Victoria Crossroads. Elsewhere, sufficient moisture will still be in play for isolated sea breeze showers daily. By Sunday the trough begins to move westward while also starting to weaken. As it does move westward though it could provide a bit higher rain chances, mainly for the Coastal Plains. Monday through much of next week return to being dominated by high pressure which means limited rain chances.

Temperatures remain above normal daily through the period with highs from the lower to mid 90s along the coast to around 105 in the Brush Country. These values are 5 to 10 degrees above normal for this time of year. Heat index values will also be high with a few locations potentially toping 110 daily. The highest heat index values are expected Friday and Saturday and a heat advisory may be warranted one or both of those days.

AVIATION

(18Z TAFS) Issued at 223 PM CDT Thu Sep 10 2026

Convection so far today has been confined to the northern coast, around the Victoria Crossroads area. Sufficient moisture remains in place to consider potential for ALI yet, but with radar and satellite trends did take the mention out of CRP with the 18Z update. There remains an outside chance for convection as far inland as LRD and COT, but too low to include in TAFs. Outside of thunderstorm activity expect mainly VFR conditions through the period with a moderate afternoon breeze.

MARINE

Issued at 223 PM CDT Thu Sep 10 2026

Medium rain chances are expected Friday and Sunday with low chances Saturday and next week.
