Forecast Discussion:
Over the next couple days, high pressure centered roughly over the Texas Panhandle will try to press into Arizona. It will reach far enough to cause high temperatures to approach 110°F. However, by the end of the week, a large low-pressure wave will advance into the region and push the high pressure eastward, thereby "cooling" temperatures and increasing daytime breezes.
Air quality-wise, ozone is forecast to be highest today because of the high pressure overhead. Then, as wind gradually increase over the next few days, ozone levels are forecast to trend downwards.
As for PM10 (dust) and PM2.5 (smoke), both of these pollutants will remain mostly locally driven in the mornings/evenings. Their hourly forecast graphs generally reflect local, dust-producing activities. But, we can't rule out dust from dust-prone areas on breezier days later in the week.
Check back tomorrow morning for the next update!
