FORECAST
A taste of fall is on the way with the coolest temperatures since May for San Antonio.
The changes will start Saturday afternoon when youâll notice dry air/low humidity, and that dry air will remain in place Sunday and Monday. Dry air cools more efficiently than humid air, so temperatures Saturday night will quickly drop and eventually settle in the lower 60s by sunrise on Sunday. Monday morning will be similar.
Afternoon highs will still rise to near 90°, but itâll feel better because of the lack of humidity in the air.
After this eveningâs highly isolated downpours, rain chances are pretty much done until next Tuesday when the humidity returns and upper-level energy streams overhead. Not much is expected at this time on Tuesday, but Wednesday holds a bit more potential.
