An outflow boundary pushed blowing dust and wind gusts of up to 35 mph through the Phoenix metro Saturday night, triggering First Alert Days that Arizona's Family meteorologist Pete Mangione says remain in effect through Monday.
NWS Phoenix posted at 9:10 p.m. MST that the boundary was "currently progressing northward through the Phoenix Metro area," warning of gusts between 25 and 35 mph and hazy conditions from lofted dust. AZCentral and Yahoo News both reported similar blowing-dust and wind conditions bearing down on the Valley in the same weather pattern.
A Flood Watch begins at 5 p.m. Saturday and runs until 5 a.m. Sunday. Isolated areas in the eastern higher terrain could see rainfall between 0.50 and 1.0 inches. Once the watch expires, isolated showers and storms remain possible into Sunday.
Sunday late morning is expected to be dry for most of the Valley, but storm chances rise from 20% during the day to 40% Sunday night. That 40% chance of rain and thunderstorms continues through Monday evening.
After reaching 113 degrees Saturday, high temperatures are forecast to drop to 106 degrees Sunday and 100 degrees Monday. Highs settle in the 102 to 104 degree range Tuesday and Wednesday before warming back to around 105 degrees late next week.
The First Alert Days designation covers Saturday evening through Monday.
