Forecast Discussion:
Tucson saw some reasonably widespread rainfall yesterday, with a number of locations measuring between 0.04 and 0.08 inches. Tucson International officially picked up 0.04 inches, but rain gauges in the north part of the region near Tangerine and Camino de Oeste measured 0.18 to 0.23 inches!The low that brought the rain to the area yesterday is now moving east into Oklahoma, with another weak disturbance moving through the state this morning, but you likely won't even notice it is moving through. The main weather feature is high pressure building into the Southwest US and will stay over the area through Friday. This will result in clearing skies and afternoon high temperatures rising back into the 70s.
This weekend, an area of low pressure that is currently just south of the Aleutian Islands will drop down the front side of the high, through Utah and into Arizona. It will stall out just south of Arizona on Sunday before moving east to start next week. This pattern shift will cause breezes Saturday into Sunday, along with increasing clouds and even a slight chance of rain. Right now, rain totals with this system are forecast to be in the 0.01-0.15 inch range. Afternoon high temperatures are also forecast to lower back into the low 60s this weekend.
As for air quality, forecasting ozone, PM-10, and PM-2.5 to be in the Good AQI category through the forecast period.
