Forecast Discussion:
It's much cooler in central Arizona this morning, thanks to yesterday's cold front. Temperatures at Casa Grande's airport dropped to at least 46°F. PM10 (dust) and PM2.5 (smoke) are running a little elevated at a few sites in western Pinal County (as of 7AM).
Looking ahead, if last week was "mild and warm," this week will be "mild and cool." Winds will be light today through Friday; daytime temperatures will start off in the 70s, barely making it into the low 80s by Friday. But, another low-pressure wave will impact the Southwest on Saturday. Breezy winds out of the southwest and cooler temperatures are expected. Then by Sunday morning, central Arizona may see its next shot at some rain. Sunday will be the coolest day of the period, with highs only in the upper 60s.
Air quality-wise, PM10 and PM2.5 will be locally driven today through Friday. Then on Saturday afternoon, pockets of dust will be possible because of the winds. However, any rain on Sunday morning would help to reduce airborne dust. Overall, both PM10 and PM2.5 are forecast in the Moderate AQI category through at least Saturday.
Check back tomorrow morning for the next forecast!
