PHOENIX -- Temperatures across the Valley shouldn't hit the 100-degree mark just yet for Mother’s Day Sunday, but they’ll be close.
High pressure building into the region from the Intermountain West will help temperatures warm into the upper 90s Sunday afternoon. We’re forecasting a high of 98 degrees for Phoenix. The average high for this time of year is 93.
As an area of low pressure to our south meanders towards Mexico, we may have just enough moisture pumping into the region that will allow isolated showers and storms to trigger with daytime heating in the mountains late Saturday afternoon, again Sunday afternoon and potentially Monday.
These showers and storms could possibly drift southwest into the Valley from the White Mountains, although the threat is very low.
Some localized gusty winds are possible for both the mountains and the Valley. Otherwise, look for a sunny Sunday morning with a few clouds building during the afternoon. Skies should be mostly sunny for Monday.
Triple digits are in the forecast for Monday afternoon across the Valley. We’re forecasting a high of 101 in Phoenix as high pressure builds. We’ll keep the low 100s around through at least Thursday.
While these temperatures aren’t record-setters, they will run a good 10 degrees above average for this time of year.
Overnight lows in the Valley will range in the low and mid 70s.
