Forecast Discussion:

The high temperature on Tuesday afternoon was 98 degrees, and that number is expected to climb further today as high pressure builds into the region. Satellite now shows high pressure moving into California as it continues moving eastward. The high will be directly over Arizona on Thursday, with afternoon high temperatures forecast to be in the 100-104 degree range today through Saturday.

The warmest day will be tomorrow, as the high will begin to move further east and weaken slightly late Thursday into Friday as several disturbances move onshore across the West Coast. A much stronger system, currently sitting about 1,500 miles off the coast of the Pacific Northwest, is expected to drop into the region late Sunday into Monday. This system will lower afternoon highs back into the 90s Sunday and Monday and increase winds into the 20-25mph range on both days.

As for air quality, with a southerly flow today through Friday, we are forecasting ozone to remain in the Good AQI category. With some transport from California possible heading into the weekend as the system approaches, we may see a slight uptick in ozone, with the daily 8-hour average rising into the Moderate AQI category both Saturday and Sunday. As for PM-10 (dust), expecting it to remain in the Good AQI category through Saturday; however, with the stronger winds coming in on Sunday have raised concentrations into the Moderate AQI category to account for some blowing dust.

Have a great Wednesday!
