A big temperature drop is in the forecast.
The new work week starts with a cold front sweeping across the Sonoran Desert. This front’s first act will be gusty west winds that develop this afternoon.
Westerly wind gusts approach 25 MPH in Tucson today, while areas near the New Mexico border could see gusts near 40-50 MPH. Eastern Cochise, Graham and Greenlee Counties are under a Wind Advisory from 11 AM until 7 PM today. Patchy blowing dust can’t be ruled out near the Willcox Playa along I-10.
Breezes decrease after 8-9 PM.
Highs today peak in the upper 60s, which is 10° cooler than Sunday, but a few degrees above average for late January.
The cold front’s final act will be a sharp temperature drop. Daytime highs struggle to reach the mid 50s Tuesday, running 20-25° cooler than Sunday. Lows Tuesday night bottom out in the low 30s. Areas outside of Tucson city limits likely wake up to freezing temperatures Wednesday morning.
Temperatures rebound later in the week, returning to the low 70s Friday through the weekend.
