FORECAST

Halfway through the work week!

After another warm day, we’ll be on on cold front watch this afternoon. The front is expected before dinnertime. Humidity levels will quickly drop behind the boundary, leading to a clear, cool morning on Thursday.

San Antonio likely dips into the low-50s and upper-40s to start the day on Thursday. Daytime highs will be *slightly* cooler tomorrow afternoon. Friday morning will be the coolest of all, with lows in the mid-40s in the Alamo City.

A slight warm up is expected this weekend as more humidity pumps in by Sunday. Then, changes arrive, as a stronger cold front moves in early next week.

Often with these early-season cold fronts, forecasting exact times and strength can be a little tricky (models don’t handle them well). But, the latest thinking is that the front will make a push through Central Texas on Monday. That would mean gusty winds are possible, along with a few showers along the front. Cooler weather is forecast for Tuesday, with a secondary push of colder air for Wednesday. More updates to come!
