Overview
- National Weather Service guidance calls for numerous to widespread showers and a few storms from Wednesday night through Friday, focused along the coast and Gulf.
- Houston faces high rain odds of 50–90% with about 1 to 2 inches expected by early Saturday before a drier weekend returns.
- South-Central Texas holds 30–60% rain chances Thursday and Friday, with roughly a half-inch along the I‑35 corridor and locally much higher totals possible on the coast.
- Forecasters note uncertainty tied to the speed of the front and the potential involvement of a Pacific cut-off low that could boost rainfall, especially toward the coast.
- Bexar County remains in severe to extreme drought and the Houston area in moderate to severe drought, as the CPC outlook favors a slightly warmer and wetter-than-normal December.
