DISCUSSION
Issued at 1112 AM CST Sat Nov 15 2025
The subtropical ridge across Texas gradually nudges back out over the Gulf by mid to late week, as the next low swings from Baja California into the Southern Plains. At the surface, moisture begins to increase on Wednesday, with a frontal boundary approaching Thursday into Friday. There is a very low, less than 10 percent, chance of rain through Wednesday, and a medium, 30-40 percent, chance Thursday into early Friday. Well above normal temperatures persist with record to near record highs Sunday through Thursday. Behind the front, temperatures only dip back towards normal or slightly above normal. As the pressure gradient strengthens mid-week, expect breezy southeasterly winds Wednesday and Thursday, especially each afternoon.
AVIATION

MARINE
Issued at 1112 AM CST Sat Nov 15 2025
