San Antonio rolled into Monday feeling more like early summer than a typical mild morning, waking up to cloudy, muggy air with readings near 68F and dewpoints in the low 60s at Kelly Field. Skies will turn mostly sunny and the city will warm up fast this afternoon, with a high around 83F. That early season heat hangs around into Tuesday and Thursday, when daytime highs are expected to climb into the upper 80s.

Afternoon Winds Pick Up

Southerly breezes will crank up later today and could gust around 20 to 25 mph in exposed spots, enough to rattle patio umbrellas and make it feel even warmer. It is a repeat of the same fog-and-breeze pattern we saw Sunday, covered in yesterday's same fog-and-breeze pattern.

Midweek Storms Possible

The setup turns more active by midweek as Gulf moisture streams back into the area. Showers and scattered thunderstorms become more likely by Wednesday, with a few storms capable of brief heavy rain and gusty conditions. The National Weather Service Austin/San Antonio notes that timing and coverage are still uncertain, so this is one of those weeks where checking back on the forecast is worth your time.

Plan Ahead

Keep outdoor plans flexible later in the week and secure loose patio furniture before those gusty afternoons kick in. A light rain jacket is a smart add-on for Wednesday errands, and it would not hurt to check the forecast before any weekend events in case storms end up more widespread than currently expected.
