San Antonio is starting Sunday in fog and mist, but the bigger weather story is already lining up: showers and thunderstorms are expected to move through the city and along the I-35 corridor this morning before a sharp turn cooler. The forecast calls for a mostly cloudy day with a high near 63, and some storms could bring brief heavy rain and gusty winds. By Monday, the city is looking at a gray, chilly high near 54.
Storms Arrive Sunday Morning
The National Weather Service says rain and thunderstorms are likely Sunday, with the most active window running from morning into early afternoon. Rain chances are around 80%, with roughly one-half to three-quarters of an inch possible in the San Antonio area; northeast winds of 5 to 10 mph could gust to 20 mph. A few stronger storms are possible along and east of I-35, though no watches, warnings or advisories are currently listed.
Cooler Air Takes Over By Monday
Showers should taper Sunday afternoon, but clouds and a north-northeast breeze will keep the evening damp and raw. Sunday night lows should fall to around 52, while gusts are forecast near 25 mph. Monday stays mostly cloudy with a high near 54 and a steady northerly breeze.
The updated timing sharpens the earlier outlook published by Hoodline: San Antonio now faces its wettest stretch Sunday morning and early afternoon, followed by the coldest air of the week.
A Brief Midweek Rebound
Tuesday brings mostly sunny skies and a high near 63, followed by a mostly cloudy Wednesday near 68. Temperatures then climb into the low to mid-70s Thursday through Saturday, though low rain chances return, including a 30% chance of showers Thursday and slight chances Friday and Saturday. For Sunday plans, keep rain gear handy and allow extra time for slick roads during the morning storm window.
