Forecast Discussion: Yesterday turned out to be a good day, Sky Harbor received 0.23" of rain while much of the valley received closer to a half inch. Rain has many benefits when living in a desert, but with respect to air quality, the rain will stabilize soils which will help prevent a windblown dust event in the near future. Getting as much rain as possible this time of year is especially beneficial because April through June are typically the driest months, and therefore pose the greatest threat of major dust events. Looking ahead, ridging will begin to establish itself over the region causing light winds, mostly clear skies, and warm temperatures in the days to come. Temperatures are expected to continue rising into the weekend, likely reaching around 80 degrees. Air quality was great yesterday, with concentrations forecast to remain in the Good range through the forecast period with just a slight upward trend as the ridge produces more stagnant conditions over the region. Also of note, with all the residual moisture left over from yesterday, there will patchy fog this morning so be careful on the roads. Check back tomorrow for the latest. Until then, have a good day! –R.Nicoll
