San Antonio wakes up under a blanket of low clouds, with thick, humid air already settling over the city. Temperatures hover near 69 degrees this morning at Kelly Field, and steady southeast winds are keeping conditions mild and sticky.
Roads remain dry for now — but big changes are moving in fast.
Heat Builds Fast This Afternoon
Skies are expected to gradually clear, allowing temperatures to surge to 88 degrees later today. That’s well above average for early March, giving the city a summer-like feel before spring has fully arrived.
South-southeast winds will increase to around 15 mph, with gusts near 20 mph, adding to the warm and breezy conditions.
If you have outdoor plans, today is the better window — because midweek brings a shift.
Storm Chances Increase Overnight
A slight chance of drizzle develops after 3 a.m., but the real action begins Wednesday.
Rain chances rise sharply through the morning, with showers becoming likely by afternoon and thunderstorms possible as highs reach around 86 degrees. Rain coverage peaks near 60 percent during the day and continues into Wednesday night.
While widespread severe weather is not currently expected, repeated rounds of rain could cause brief ponding on major roadways like Loop 410 and I-35, especially during heavier downpours.
Warm Pattern Continues Through the Week
The unsettled stretch doesn’t end Wednesday:
- Thursday: High near 87°, 30% chance of storms, mainly before midday
- Friday: High near 85°, scattered showers possible
- Saturday: Storms possible, high near 84°
- Sunday: Showers likely, cooler high near 80°
Temperatures remain well above seasonal norms, and the broader outlook favors continued above-average warmth across South-Central Texas into early next week.
What You Should Do Now
- Plan outdoor activities earlier today before storms build
- Secure loose outdoor items as winds increase
- Allow extra stopping distance during heavier rain bursts
- Stay weather-aware midweek as storm chances grow
Don’t Forget the Time Change
Clocks spring forward at 2 a.m. Sunday, March 8, bringing longer evenings and more daylight — perfectly timed with this extended warm spell.
San Antonio gets one more hot, breezy day before rain and storms roll in. Enjoy the sunshine while it lasts.
