Heat Advisory and chance of thunderstorms for San Antonio on Saturday

SAN ANTONIO (KTSA ) — If you are hoping for some different weather patterns for the Alamo City and the surrounding area, you might be in luck on Saturday.

While the risk is considered marginal, the National Weather Service is calling for a 20% chance of thunderstorms during the afternoon hours, but those chances go as high as 50% by Saturday night.

Sunday brings a 20% chance of thunderstorms, but it is hard to predict where or when they may develop.

In a familiar setting, dangerous summertime heat will continue on Saturday with a high 103, which will downgrade Friday’s Excessive Heat Warning to a Heat Advisory through 7 p.m.

Rain or shine, Sunday should bring a high of about 100 before temperatures start falling below the century mark early next week.

NOTE: For those who have to work outside, it will be important to take appropriate precautions. The same can be said for those enjoying recreational activities outdoors.

Drinking plenty of water and taking frequent breaks, preferably in an air-conditioned environment, are strongly recommended.

Never leave young children or pets unattended in cars or trucks as the temperature can rise 20 degrees in as few as 10 minutes with the windows rolled up during the hottest times of the day.
