Monday’s Tucson Forecast: Winter’s last stand?

The work week starts warm. The weekend could feel much different.

Expect daytime highs in the low 80s this afternoon through Wednesday. Much like last week, a southwesterly flow aloft carries in patches of Pacific cloud cover from time to time. Partly cloudy skies should prevail this afternoon and tomorrow.

Developing off the Pacific Northwest coast is a strong low pressure system. This storm system looks to be the dominant weather by mid week. Isolated showers can’t be ruled out Wednesday, followed by gusty winds Thursday into the weekend. Highs late in the work week peak in the mid to upper 70s.

This weekend may feature scattered showers, mountain snow and cooler temperatures. While rain chances for Metro Tucson sit at 30%, there is considerable differences in the GFS and European model with this storm system. The GFS model brings a cold front into southern Arizona, while the European model keeps the front north of the Sonoran Desert.

Exact rain/snow totals are unclear, but temperature should hover around the 70° mark starting Saturday.
