NWS Forecast Office Phoenix, AZ

Morning lows will be relatively mild today and through this unprecedented March heat wave that will last into the weekend, but don't let these mild mornings fool you. Temperatures will quickly warm into the 80s by mid morning and then 90s late morning, followed by triple digit highs during the afternoon. Don't underestimate the heat. Reduce outdoor activity during the heat of the day, take frequent breaks in the shade or in air conditioned spaces, and stay hydrated!
