Forecast Discussion: Yuma will see daytime highs in the upper 90s, close to 100°F through Tuesday under mostly sunny skies and fairly light winds. Another breezy, cooler system will move through on Wednesday, dropping highs into the lower 90s. The question of dust with Wednesday's event relies on two things: wind speed and wind direction. Right now models suggest speeds could be around 10 to 20 mph are late Tuesday night, but much lighter on Wednesday. This is good. The direction of the strongest winds are forecast to be out of the southwest. Again, this is good as most dust we see in Yuma comes from the west-northwest. For now, we are keeping forecast PM10 levels in the upper Good range through Tuesday, and likely no higher than the lower Moderate range on Wednesday. Ozone concentrations are expected to increase on Monday and Tuesday as the approaching system will favor some import from southern California. Concentrations should climb no higher than the middle Moderate range as well. Check back tomorrow for more. Until then, have a good day! -J.Paul
