DISCUSSION

Issued at 204 AM CDT Sat Sep 5 2026

The weakening mid-level low continues to move southwestward towards Mexico early this morning, ushering moisture into South Texas. Above normal PWATs in the Victoria Crossroads (2.1-2.3") and elsewhere around 2", will help with the formation of seabreeze convection through this Labor Day Weekend. Ultimately, coverage looks to be best over the Victoria Crossroads with less coverage further south and west. Low rain chances (20-40%) continue Monday and Tuesday, mainly due to the afternoon seabreeze. Going into the middle of next week, a mid-level low/trough progresses westward across the Gulf, riding the southern periphery of the ridge. This mid-level feature will act as an additional lifting mechanism to the seabreeze, increasing rain chances Wednesday to 30-60%.

Temperatures will continue to remain above normal. However, with the increased chance for rain showers, some locations could see increased cloud cover, thus bringing temperatures more closer to normal temporarily. Otherwise, we will be flirting with heat advisory criteria with heat indices ranging from 105-110 across the area through the middle of next week. Nonetheless, a moderate to high heat risk will be present each afternoon.

Similar conditions can generally be expected overnight with VFR conditions becoming somewhat restricted during the early morning.
