Rather dry and cool air has settled over South Texas and we start Tuesday with pleasantly cool conditions under mostly clear skies. High clouds associated with an upper level disturbance emerging out of Northern Mexico will shift southward by afternoon. This means mostly sunny skies for Tuesday afternoon and highs in the middle 70s.

High pressure aloft shifting east starts a significant warming trend beginning Wednesday. As surface winds turn south, we’ll see partly cloudy skies and afternoon highs in the 80s to near 90 by Friday.

At that time another strong cold front enters the picture with some storms and cooler temperatures to start the weekend. Overall the chances of rain are somewhat low with most of the activity to the north and east of the San Antonio region. But some strong storms are possible along and east of highway 77 Friday night.

Temperatures drop about 20 degrees for the weekend, with highs in the 70s and lows in the 50s.
