FORECAST
PREPARE TO DODGE SPOTTY AFTERNOON RAINFALL
A weak disturbance, combined with some added moisture in the atmosphere should bring isolated, afternoon pop-ups. Today’s rain chances sit at 20%. Slightly higher odds will exist south and east of SA. Thursday presents our best shot at downpours, with a 30% chance of rain.
Future radar at 4pm Wednesday (9/9). Spotty rainfall is possible today. (Copyright 2026 by KSAT – All rights reserved.)
PERISISTANT HEAT
Despite rain chances, the hot temperatures show few signs of letting up. Yesterday, San Antonio achieved its 19th day at 100° or above. Upper-90s will be the norm going forward, but a few days could see temps briefly touch 100° again.
Upper-90s will be the norm going forward, however, San Antonio could briefly touch 100 by the weekend (Copyright KSAT-12 2026 – All Rights Reserved)
VERY QUIET ATLANTIC
September 10th is the peak of Atlantic hurricane season. Yet, the Atlantic is impressively quiet. El Nino is likely playing the biggest role in keeping tropical activity at bay. It appears that this season will set the record for latest first hurricane (should we ever get one).
