PHOENIX — It's a hot and humid start to the week in the Valley!
High pressure to our east is bringing lots of moisture into Arizona and keeping monsoon storm chances in play through the middle of the week.
Scattered storms will be possible again across the high country and in eastern and southeastern Arizona on Tuesday.
Here in the Valley, we could see a few spotty showers and areas of blowing dust in the afternoon.
The biggest hazards with any storms that develop across Arizona will be strong winds, dangerous lightning and small hail. We could also see 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.
Our forecast will dry out by the Fourth of July, ushering in another round of scorching heat.
Valley highs will soar above 110 degrees and even approach 115 by Friday.
Phoenix temperatures will likely end up within a degree or two of the records on Friday and Saturday. The current record high for both days is 116 degrees.
Overnight lows will stay warm too, only cooling into the upper 80s to low 90s.
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.
An Excessive Heat Warning is already in effect through Friday night for areas along the Colorado River in southwestern Arizona.
Another Excessive Heat Warning will be in effect for areas in northwestern Arizona, across Mohave County, from Thursday morning until Monday evening.
We could see more of these heat alerts issued across other parts of our state in the coming days.
