FORECAST DISCUSSION

Storm activity decreases today, but temperatures make a run at the record books.

This afternoon features a 20% chance of metro storms. Storm activity should favor the mountains and International Border. Tucson’s forecast high of 108° would match the record set on this date in 2006. Overnight lows drop to the low 80s under partly cloudy skies.

A similar scenario plays out to start the weekend, with lots of heat and few thunderstorms. Saturday’s record high of 109° set in 1987 should stay intact, but highs may come a degree or two within this mark.

Tropical Storm Frank off the Mexico coast passes west of Baja California next week, triggering a surge of moisture into southern Arizona. Scattered storm chances return Sunday, with rain chances increasing to 50% Monday through Thursday. Daytime highs decrease to the 100-102° range for the upcoming work week.
