PHOENIX — Sizzling heat and increased monsoonal moisture continues into the start of the week before we dry things out just in time for the Fourth of July.
High pressure to our east is pushing closer to the desert southwest and sending ample amounts of moisture into our state. We could see monsoon storms impact Arizona over the next few days.
Here in the Valley, chances will be highest Sunday evening into Monday morning and then again Tuesday into Wednesday.
The biggest hazards with any storms that develop across Arizona will be strong winds, dangerous lightning and small hail. We could also see some downpours and areas of flooding, especially along burn scars, so stay weather-aware and remember to never attempt to drive through flooded washes or roadways.
A Blowing Dust Advisory is in place for Pinal and Pima counties until 10 p.m. this evening.
A drying trend by the end of the week will set up as a ridge of high pressure from the west pushes into the region bringing much warmer and drier air into Arizona.
High pressure will keep lows in the 90s this week and send daytime highs soaring above 110 degrees too.
An Excessive Heat Warning has been issued for Sunday morning through Friday night July 5th along the lower Colorado River Valley from Parker down to Yuma.
The warm mornings combined with the sizzling hot afternoons will increase the risk for heat illnesses, so make sure that you're staying hydrated and limiting your time outdoors during the hottest hours of the day. Keep an eye on kids and the elderly as they are more susceptible to heat-related impacts.
