Arizona weather forecast: Record-breaking highs expected soon in Phoenix
Evening Weather Forecast - 3/12/26
The Valley will cool into the low 60s through Friday morning, and climb to 93 degrees Friday afternoon.
PHOENIX - Thursday was a hot and sunny day in the Valley. Temperatures soared nearly ten degrees compared to yesterday’s high, reaching 92 degrees in the Valley. This was near-record heat today for Phoenix, but the area is set to break record-highs on Friday.
Tomorrow:
The Valley will cool into the low 60s through Friday morning, and climb to 93 degrees Friday afternoon. Temperatures will climb in the high country as well, with a high of 70 degrees in Flagstaff, which will be a record-tying temperature!
The weekend:
More highs in the low 90s and lows in the low 60s are expected. The high country will see temperatures in the 60s and 70s over the weekend. Saturday and Sunday will be a few degrees cooler than Friday in far northern AZ, thanks to a storm passing through the Rockies. Partly cloudy skies are expected on Saturday across the state, also thanks to the storm in the Rockies. Sunday will be a sunnier day.
Next week:
Even stronger high pressure will move over Arizona next week, and temperatures will climb into the 100s on Wednesday through Sunday in the Valley. This is unprecedented heat, since it will be the earliest the Phoenix area has ever hit 100 degrees. It will be our warmest March temperature on record, and it will be the most amount of 100 degree days in a row that we have seen this early in the season.
