As Southern Arizona awaits this weekend’s Winter storm, highs today run 4-6° above average. Metro Tucson tops out in the low 70s this afternoon. Winds today will be much lighter than yesterday, peaking around 5-10 MPH out of the west.
Friday looks to be the transition day, as cloud cover and winds start to increase. There is a slight shower chance tomorrow afternoon and evening. The cold front enters the state Saturday, elevating southerly winds in the 20-40 MPH range.
Primetime for valley rain & snow above 6,000 feet looks to be Saturday evening through the first half of Sunday. A few rumbles of thunder can’t be ruled out as well. Valley floors could pick up 0.40-0.80″ rainfall, while Mount Lemmon may be in line for 10-20″ snow.
Drier weather prevails early next week, courtesy of high pressure parking over the state. Low to mid 70s return for daytime highs Tuesday and Wednesday.
