Here's what you can expect:

* High temperatures in the 100 to 105-degree range in and around San Antonio on Saturday, Sunday and Monday.  Dropping humidity levels during the afternoon hours should keep heat index values from jumping out of control.  

* Areas to the west of San Antonio, along the Rio Grande, should experience even warmer temperatures.  Highs in the 105 to 110-degree range are possible. 

* Record high temperatures are in jeopardy at San Antonio International Airport for Friday through Monday.  

* A pattern change will bring more cloud cover and cooler temperatures by the middle and end of next week.
