Overnight, scattered showers and a chance of storms are possible as a summer "cold front" moves into the San Antonio area. It is rare to see a front this time of year that has the kind a muscle this one has, to move through and south of the city. We do expect a few showers along the front overnight, a slight chance of an isolated thunderstorm, but nothing severe expected.  

Rain chances pick up between 2 and 5 am and linger until about 9 am. We should be done with all rain by noon at the latest; we should even see some afternoon clearing and sun. 

Highs will reach 90–91 Tuesday and the lower 90s Wednesday and Thursday before we go back to the mid 90s Friday and the weekend. Wednesday and Thursday morning should be nice and comfortable, with temps in the mid to upper 60s with a north breeze.
