MOST ACCURATE FORECAST: Chance of storms overnight in the Valley!

Posted
and last updated

PHOENIX — Phoenix is in the middle of the longest stretch of triple digit days ever!

As of Tuesday, Phoenix has had 86 triple-digit days in a row and there is no end in sight. The previous record was 76 consecutive triple-digit days set in August of 1993.

Our only hope for a little relief would be a good round of monsoon storms to cool things off. Chances for that to happen will be increasing over the next 48 hours.

Starting overnight into Wednesday morning, a few showers and thunderstorms are possible in the Valley.

Storm chances will increase even more on Wednesday night and again on Thursday night as a disturbance passes to our south and more monsoon moisture flows in.

Any storms that develop will be capable of bringing strong gusty winds, blowing dust and low visibility, dangerous cloud-to-ground lightning, heavy downpours, and flooding (especially near wildfire burn scars.) So stay weather-aware and seek shelter if/when storms move in.

As storm chances go up, forecast temperatures will drop closer to normal for this time of year. Phoenix will top out around 106 or 107 degrees on Wednesday, Thursday and Friday with overnight lows in the mid 80s.

Heading into the weekend, a storm system moving through the Pacific Northwest will pull drier air into Arizona. That will clear out monsoon storm chances across our state and drive up temperatures.

Phoenix will likely be back up near 110 degrees by the start of next week.
