Forecast Discussion:

A new daily high temperature record was set in Yuma yesterday (Thursday), with the mercury reaching 81°F. It was also breezy in the afternoon, which resulted in a modest increase in PM10 (dust) levels. Nevertheless, PM10 remained in the Good Air Quality Index (AQI) category.

Looking ahead, near-record temperatures are expected again today and Saturday as a strong high pressure continues to exert its influence over the region. Breezy northerly winds will also continue both days because of the proximity of the jet stream overhead. In terms of air quality, we will likely see a similar outcome as yesterday: modest PM10 increases, but PM10 staying in the Good AQI category.

Things calm down a bit on Sunday before another low pressure wave dives into the region on Monday. This next weather maker is expected to help cool down temperatures, dropping highs to a few degrees below normal by Tuesday (i.e. mid-60s). Of course, with such temperatures swings, we can expect stronger winds. Currently, 20-30 mph winds out of the north are looking possible mid/late afternoon Monday and into the night. PM10 levels are forecast to increase during this time.

But that's not all. Believe it or not, rain may be possible later Tuesday, and even Wednesday. We'll have a better idea of potential rainfall amounts on Monday.

No issues with ozone or PM2.5 (smoke) are anticipated at this time.
