San Antonio is facing a warm, changeable Mother’s Day weekend with fog and spotty showers this morning, a hot and sunny afternoon on Sunday, and a cold front that could spark stronger storms after 6 pm. The forecast covers today’s lingering mist, the afternoon 30% storm chance, Mother’s Day heat in the lower 90s, and the likelihood of storms after sunset that could bring gusty winds and hail to parts of Bexar County. Local meteorologists say most rain should clear out overnight, leaving a mostly sunny and warm week ahead across the area.
This morning begins with pockets of fog, mist, and a few light showers across the San Antonio metro area, reducing visibility in spots and making commutes a touch slower. Not everyone will see measurable rain, but scattered, spotty cells are possible as the atmosphere stays humid. Expect highs to climb into the upper 80s by the afternoon with sticky humidity that will make it feel warmer than the thermometer reads.
On Mother’s Day daytime skies should be mostly sunny and hot, with temperatures reaching the lower 90s for many neighborhoods in and around San Antonio. The heat will dominate the daytime hours, so outdoor plans will need shade, hydration, and sunscreen to stay comfortable. After sunset, attention turns to a cold front pushing through the region, and that front is the main trigger for storms that will likely develop after 6 pm.
Storm chances ramp up in the evening as the front lifts instability and triggers showers and thunderstorms across Bexar County and nearby counties. Some of those storms could be strong, producing gusty winds capable of downing branches and causing localized damage, and there is a nonzero chance of hail in the stronger cells. Lightning, heavy downpours, and brief gusty bursts are the main threats to monitor during the overnight period.
Timing is important: the most likely window for stronger storms is after 6 pm and into the late evening, tapering off overnight, with most activity expected to end by about 2 am Monday. That overnight ending should usher in a quieter pattern for early next week, with sunshine returning and temperatures remaining above average. Daytime highs next week should be pleasant and warm, offering a stretch of stable weather after the weekend’s disturbance moves through.
If you have outdoor plans on Sunday afternoon, take sensible precautions for the heat and for the later storm threat; bring water, pick shady spots, and have a plan to move indoors if lightning or strong winds develop. For evening events, keep an eye on the sky and have a weather app or radio handy to get warnings if a stronger storm approaches. Drive carefully through damp spots and avoid standing water on roads if showers or bursts of heavy rain appear.
We’ll be watching live Doppler radar and local updates to track where storms form and whether any need to be upgraded for severe weather. Local meteorologists will update forecasts as radar data and storm reports come in, so check for updates if you’re heading out for dinner or evening plans. The goal is to keep you informed so you can celebrate Mother’s Day safely and still enjoy much of the warm daytime weather.
