Excessive heat warning finally over, cooler Friday on tap

Posted: Updated:

PHOENIX – After two weeks, an excessive heat warning cover the Phoenix metro area has finally expired. After several extensions, the National Weather Service canceled the warning, which was supposed to run though the weekend. The NWS had extended it once again Thursday, mostly because we just haven’t been cooling off much at night.

Things have changed a bit for the cooler though.

With drops of just a couple of degrees, the weather forecast for the next few days is looking not quite as hot as it was just 24 hours ago.

The morning sky was hazy all over the Phoenix metro area after an early morning dust storm rolled through between midnight and 2 a.m. While it wasn’t a major storm, the 30 to 40 mph winds did bring some cooler air. That’s what prompted the NWS to cancel the excessive heat warning that had been in effect since Aug. 22.

Some areas of the East Valley got some light rain, mostly just sprinkles, in the early morning hours. Those showers were moving from south to north. The West Valley saw mostly cloudy skies early on, but did get some sprinkles.

Those showers are going to fizzle out as the day goes on so it probably won’t be a very active day weather-wise.

The dew point was all the way up to 68 degrees Friday morning. There’s a slight chance of rain Friday evening.

Plan on a high of 105 -- well below the 110 we've been seeing and almost on par with the seasonal average -- Friday, followed by 109 under partly sunny skies both Saturday and Sunday. It’s going to be mostly dry through the weekend.

The chance of storms returns to forecast Monday evening and into Tuesday and will continue through the first part of the work week. We’re also looking at some slightly cooler, albeit still above average, daytime highs.

We've had 32 days of 110-plus temperatures this year, which ties the record set in 2007. Thursday it looked like we were going to break that record, but with the significantly cooler forecast for Friday -- yes, 105 is cooler -- that's probably not going to happen now. At least not on Friday.
