Phoenix Weather Report for Nov 24th, 2020
Forecaster: Waters, S.
A passing storm to our north ushered in some dryer and cooler air, which will manifest in cooler daytime highs for the next several days.
Today we’re seeing a few of the wind gages gusting above 15mph but this should not increase through the day. Highs this afternoon under sunny skies will range from the mid-60s in places like Aguila and Carefree to the low 70s for greater Phoenix and Gila Bend.
Overnight lows will be mostly in the low to mid-40s. Tomorrow’s highs will range from the upper 60s to low 70s, again under sunny skies.
Skies will be partly cloudy on Thursday with very little change in afternoon temps.
Air Quality Forecast
ADEQ Meteorologist: M. Pace
The high yesterday in Phoenix was 80 degrees, and it should be the last 80-degree day for at least a week (I can’t bring myself to say last for the year). While the average last 80-degree day is Nov 22nd, it is certainly not out of the question to see the 80s in December. For example, in 1980, there were seven 80 degree days, and since this year has been running a bit on the warm side, thinking we will see at least one more “hot” day, especially during the first week of December.
Today, forecast high temperatures are in the low 70s due to a trough that moved through the state late yesterday into this morning, ushering in much cooler air. A weak ridge of high pressure will briefly build over the state tomorrow before another trough will swing through late Thursday into Friday, reinforcing the cooler air. As a result, afternoon high temperatures are forecast to stay in the low to mid-70s through at least Saturday.
While no rain will be associated with this second system, it will increase northwest/north winds late in the day on Thanksgiving into Friday. With residential fireplace use likely to increase for Thanksgiving, these winds will help to keep PM-2.5 (smoke) concentrations slightly lower than they otherwise would be. Still forecasting both PM-10 and PM-2.5 to be in the Moderate AQI category through the forecast period.
