Synopsis and Discussion
Two ozone monitors (Blue Point and Fountain Hills) recorded levels exceeding the Federal health standard on Thursday. In fact, much of the east Valley saw concentration in the mid to upper "Moderate" range while the west Valley remained mostly in the "Good" range. A light west to east flow will continue through the Memorial Day weekend with high pressure to the southeast and a deep trough of low pressure to the northwest. Afternoon desert temperatures will range from 98°F to around 102°F under sunny skies. Indications are that ozone levels will be slightly lower this weekend, but the highest concentrations will again be in the east Valley. Extra traffic on Monday could edge concentrations up a bit. PM10 levels are also forecast to stay in the "Good" range this weekend.
Excluding the 0.04 inches of rain that fell at Phoenix Sky Harbor on April 22, the last significant rainfall was on March 23. That was 65 days ago. The month of June is typically one of the driest for Phoenix, and the models are suggesting nothing different. If we make it through all of June without rain, it would the streak to 98 days. We are entering a critical time period for wildfire potential in Arizona, including the Phoenix metro area. Fire equals smoke which equals poor air quality. Therefore, remember to be careful with barbecues, campfires and cigarettes over the next several weeks.
Check back on Sunday for the latest. Until then, have a safe and enjoyable Memorial Day weekend! -J.Paul
