FORECAST HIGHLIGHTS
FORECAST
OVERNIGHT AND WEDNESDAY
As night falls, don’t be surprised if you spot a few stray sprinkles in the sky. Tomorrow, just a couple of isolated showers may make an appearance, but any rain accumulation will be minimal.
RAIN CHANCES ON THURSDAY/FRIDAY
Get ready for some moisture as Tropical Storm Vance moves northward ahead of a storm system on Thursday. This could create a band of heavier rain along the Rio Grande, particularly west of San Antonio. Residents in San Antonio might see a few passing showers from Thursday through late Friday, but rainfall totals are expected to stay below half an inch. On the other hand, areas along the Rio Grande could receive between 1 to 3 inches of rain.
Potential rainfall accumulation over the next 5 days. The best odds for 1″+ rainfall will be east of I-35.

HALLOWEEN UPDATE
Looking ahead to Halloween, expect a shift to a calmer weather pattern. While we can’t completely rule out a shower, the chances of rain are low. With more sunshine, temperatures are likely to climb above 80 degrees during the afternoon. By the time trick-or-treaters hit the streets, most areas will be enjoying comfortable temperatures in the 70s.
