PHOENIX — We’re now on day three of monsoon season, with isolated storms returning to the forecast.
Most of that activity will stay across the high country and southeast Arizona today. Here in the Valley, any rain chances will mainly be tied to outflow boundaries drifting in from those storms — so expect periods of gusty winds, areas of blowing dust, and the possibility of a brief, spotty shower this evening
The heat will once again help fuel storm development statewide. Phoenix is expected to flirt with 110 degrees this afternoon, running about five degrees above average for this time of year.
Extreme heat is also a concern across northern Arizona. Extreme Heat Warnings are in place for the Grand Canyon as temperatures near the bottom approach 110 degrees. The warning remains in effect for areas below 4,000 feet through 8 p.m. Thursday.
Be sure to stay hydrated and limit outdoor activity during the hottest part of the day.
Back in the Valley, breezy conditions develop this afternoon with gusts up to around 25 miles per hour — especially if outflow boundaries move through.
Looking ahead, drier air begins to move in by the end of the week, allowing temperatures to ease closer to seasonal averages heading into the weekend.
Father’s Day is shaping up to be sunny and dry, with a high near 105 in Phoenix.
However, high pressure rebuilds across the Desert Southwest next week, sending temperatures climbing back toward 110 degrees and potentially higher.
