Temperatures in Tucson are headed up — a lot. The forecast shows temperatures here for the second half of the week will be from 20 degrees to 25 degrees above normal. That'll be hot enough to break March weather records, the National Weather Service said Monday.

Tuesday's high temperature is expected to be 92 degrees. It will jump to 101 degrees on Thursday and 103 degrees on Friday, the weather service said.
