Forecast Discussion: A changing of air masses is now underway. Recent observations in the Yuma area show dewpoints have climbed nearly 20 degrees into the low 70s since 8 AM. Quick rises in surface moisture under southerly winds are a good sign of an incoming moisture surge. The cause is likely from collapsing thunderstorms over Mexico last night. Moist and unstable conditions for Arizona are expected to continue into the weekend. As storm activity increases over the deserts, so does the outflow and blowing dust threat. It appears that late Friday night into Saturday morning a large outflow from central Arizona could bring strong east winds, dust, and eventually thunderstorms towards the Colorado River Valley, including Yuma. Moderate PM-10 readings are possible. More rainfall is then anticipated Saturday night. Unlike PM-10, ozone should remain in the Good AQI given expected cloud cover and wind directions being primarily out of the south. Check back on Friday for a closer look at the weekend's weather and air quality. Until then, have a good day! -J.Malloy
