PHOENIX -- Most Valley towns should top out in the upper 90s for the Memorial Day weekend as a trough of low pressure keeps temperatures from hitting the century mark.
Expect sunny to mostly sunny skies from Saturday through Monday. Winds will become rather breezy each afternoon thanks to a tight pressure gradient while a ridge of high pressure remains to our southeast. Speeds will range from 5 to 15 miles per hour. The strongest winds will be in Northern Arizona where sustained winds could reach 20 to 30 miles per hour.
Saturday’s high in Phoenix should be 99, with a 98 on Sunday and a 96 on Monday. Overnight temperatures will bottom out in the low 70s.
The trough of low pressure will deepen Tuesday and Wednesday, allowing some slightly cooler air to filter in. This change in air mass will drop Valley highs to 89 degrees both days. Winds will also be a little stronger and cloud cover will increase.
We’ll see a gradual warm up Friday and Saturday with highs rebounding back into the mid and upper 90s across the Valley under sunny skies.
