NWS Forecast Office Phoenix, AZ

Breezy conditions will continue on Sunday as a low pressure system just north of the area moves off towards the Four Corners. Stronger winds will be focused over the eastern/northeastern AZ high terrain. A brief light shower or sprinkle cannot be ruled out over the lower elevations, particularly during the early morning hours, but the majority of shower activity with this system will be focused over the Central and Northern AZ higher terrain. Expect afternoon highs close to 10 degrees below normal for late April, in the 70s to near 80°F across the lower deserts.

Look for warming temperatures and dry, relatively quiescent conditions through at least the first half of the coming work week. A weather system is then expected to move off the Pacific and over/near the forecast area during the latter half of the week. Plenty of uncertainty remains with the extent of rain chances, potential rainfall totals, and the potential for thunderstorms (particularly Thursday afternoon). However, rain chances late Wednesday into Thursday are currently low, between 10-20% for portions of the South-Central AZ lower deserts and up to around 30% for higher terrain areas north and east of the Greater Phoenix Area. Stay tuned as details become more clear over the next few days.
