Tuesday’s Tucson Forecast: Chasing historic heat today

Weather whiplash on the way.

For the first time this year, Tucson is expected to reach 95° this afternoon. The Old Pueblo usually reaches 95° around May 1st. While it is earlier than usual, today’s 95° forecast high will not be the earliest on record. Tucson’s earliest 95° day belongs to March 5th, 1910.

High pressure sliding across the state keeps highs in the mid 90s tomorrow. Tucson likely ties Wednesday’s record high of 95°, set in 1988.

A powerful cold front approaches northern Arizona later in the week. Ahead of the front, gusty winds up to 30 MPH are possible Thursday. These winds combine with low relative humidity and dry vegetation to ramp up the wildfire risk. Southern Arizona is under a Fire Weather Watch late Thursday morning through Thursday night.

Daytime highs drop off 20-25° between Wednesday and Friday, only reaching the low 70s to wrap the work week. Lows crash to the low to mid 40s across Metro Tucson waking up Saturday morning. Saturday afternoon features highs in the upper 70s with gusty winds lingering.

Long range models indicate a warming trend early next week. Expect temperatures in the mid to upper 80s as soon as Sunday.
