PHOENIX — It's a hot week in the Valley as we continue our first long stretch of triple-digit days this year.
As a storm system sits to our south, moisture is moving in too.
That moisture, combined with our daytime heat, is leading to showers and thunderstorms across Arizona. It is looking like and feeling like a little preview of what we typically see during the monsoon.
Storms will fire up across the higher terrain in northern and eastern Arizona first each afternoon, then we'll see a chance for some showers or thunderstorms in the Valley after that.
Gusty winds and blowing dust will be the biggest threats here in the desert.
Up north, we could see lots of lightning and areas of brief, heavy rain with any storms that develop across the high country. Small hail is possible with a few of the strongest storms, too.
Temperatures are gradually dropping throughout the week too. Valley highs will be back in the mid 90s by Friday.
The triple digits will return by Sunday as slight chances for storms continue through the weekend.
We're also still tracking a Flood Warning in effect for parts of the Gila River in southwestern Arizona as the flow increases due to water releases from the Painted Rock Dam. This warning has now been extended through May 23rd. Do not attempt to cross any flooded roadways.
