Forecast Discussion:

Yesterday (Thursday) evening, a few traces of rain were recorded for Yuma and a couple of hours of breezy winds out of the south accompanied that light rainfall. The broken cloud cover throughout the day was not enough to keep ozone from ramping up quickly. This pollutant did reach the Moderate Air Quality Index (AQI) category along with PM10 (dust).

Looking at today and the weekend, more rain is looking to roll in later this evening and throughout the day tomorrow. The National Weather Service has issued a Flash Flood Watch that is in effect for today starting at noon and is valid through tomorrow at 5 am. This is related to the possibility of heavy rainfall today and overnight. Yuma has not received much rainfall this current monsoon season, so grounds are still very dry and susceptible to flash flood conditions. By Sunday, weather conditions should calm down and get right back to those sunny, hot days.

Taking a peek at what's to come next week, Monday and Tuesday look to be 110+ degree days. Winds will remain light and out of the south-southwest. Overall, next week appears to be a break from the typical monsoon weather we've been seeing.

As for air quality, ozone is expected to be in the Good AQI range throughout the forecast period. With upcoming cloud cover from storms/showers, this should help keep ozone levels down. Early next week we could see this pollutant jump up, but we are sticking with upper-Good AQI for now with expected southerly winds. For PM10 and PM2.5 should stick to the Good AQI category as well, so long as we receive the intended rain today.

Have a great weekend!
