MOST ACCURATE FORECAST: More storm chances in the Valley this week!

Posted
and last updated

PHOENIX — Showers and thunderstorms moved through the Valley Monday night and there is a chance for more in the days ahead!

Watch out for lightning, powerful winds, blowing dust, heavy rain and localized flooding. Stay weather-aware and be prepared to seek shelter when storms move into your community.

There's a slight chance for a few lingering showers into early Tuesday morning and another chance of thunderstorms in the late afternoon evening.

Storm chances will ramp up again on Wednesday and Thursday as moisture from another tropical storm gets caught up in our monsoon flow.

This storm will be named Harold as it form in the Gulf of Mexico over the next 24 hours. It will make landfall south of Corpus Christi in Texas and continue tracking west as it weakens through the middle of the week.

Our forecast will dry out again in the Valley over the weekend and that will bring sizzling 110-degree days back on Saturday, Sunday and Monday.

Phoenix has now had 46 days this summer at 110 degrees or hotter. That's the second most ever recorded. The record is 53 days set in 2020 and we will definitely make a run at that record this year as high heat continues through August.

This year has also tied the record for the most lows in the 90s in any year. We're now up to 29 days with lows in the 90s, breaking the record of 28 days set in 2020. We will likely add a few more to this tally before the summer ends.
