Forecast Discussion: The main story for this forecast period is the anticipated passage of an upper-level ridge through the desert southwest. This ridge will build in over the region today, be firmly established over Arizona tomorrow, and will have moved eastward enough by Friday morning to put Arizona underneath a southwest, mid-level flow. Expect generally dry and sunny conditions through Friday, with high temperatures in the low 90s. Models are showing a meager surge of mid-level moisture over Yuma Friday morning into Friday afternoon, suggesting a possibility for the presence of mid-level clouds…but sunny skies should prevail. Regarding surface winds, the proverbial northerly, light winds associated with downriver drainage will be active today through early afternoon Thursday. Surface winds then shift to westerly, become northwesterly by Friday morning, and then develop a distinct southerly component Friday afternoon, while picking up to around 8mph. It seems like some of the southwesterly winds from the mid-levels may be mixing down to the surface, influencing the surface wind direction and allowing winds to slightly increase. Overall, expect there to be no dust problems Friday as winds still remain relatively light. PM-10 concentrations will remain in the Middle Good range; ozone will also stay put in the Middle Good range. Check back tomorrow for the latest. Until then, have a good day! -M.Graves
