PHOENIX -- High pressure building over the region will allow some Valley communities to hit the 90-degree mark on both Veterans Day and Tuesday.
Sunday started off with high, thin cirrus clouds streaming into the Valley. This cloud cover allowed afternoon highs to fall several degrees compared to Saturday’s high in Phoenix of 85. The official high at Sky Harbor Sunday afternoon was 83, which is still four degrees warmer than the seasonal average for this day.
On Monday, Phoenix is expected to see a morning low of 58 before rebounding to an afternoon high of 89. Tuesday should see a high of 90.
As high pressure remains in the area, a few disturbances will brush to the north of the state. This will allow some cloud cover to move in from time to time.
By Wednesday, our weather pattern begins to change and temperatures start to drop. High pressure will retrograde to the Pacific, and a trough will deepen over North America, allowing cooler air to filter into Arizona. Afternoon highs Wednesday through Friday are expected to drift down to the mid and low 80s. Next weekend, afternoons in the Valley will return to the mid 70s.
