A weather forecast for Houston, Texas, shows "Today's Outlook" with high and low temperatures. The left side describes the conditions: "Similar to yesterday! Afternoon high temperatures rise into the low to mid-90s. Overnight low temperatures drop into the low to mid-70s for much of the area, and near 80° along the coast. Scattered showers and isolated thunderstorms along the coast through the morning, expanding inland through the afternoon." Two maps display temperature ranges across southeastern Texas. The "Highs" map on the left uses a red-to-yellow gradient, indicating temperatures mostly in the low to mid-90s Fahrenheit, with some areas reaching 95°. The "Lows" map on the right uses a lighter gradient, showing temperatures predominantly in the mid-70s Fahrenheit, with areas along the coast closer to 80°. Both maps include cities like College Station, Huntsville, Houston, Galveston, and Columbus. The forecast is from the National Weather Service Office Houston-Galveston, TX, updated on Tuesday, September 23, 2025, 3:48 AM.

Showers and thunderstorms are expected to develop both ahead of and along the boundary of an approaching cold front on Wednesday. A few of these storms may become strong to severe through late Wednesday night/early Thursday morning and be capable of producing locally heavy rainfall leading to isolated street flooding and strong wind gusts. The frontal boundary may briefly linger near the coast into Thursday leading to prolonged chances of heavy rainfall. Highest rainfall totals (1-2+”) are mainly expected to occur along and south of I-10.

Hot temperatures and rain chances prevail into midweek, but drier and slightly cooler conditions await us in the wake of a midweek cold front.
