Forecast Discussion:

It was a warm weekend, with high temperatures in the mid-70s on Saturday and Sunday, which is about four degrees above average for this time of year. Don't worry; cooler weather arrived today and tomorrow but will be short-lived.

Water vapor this morning shows a trough of low pressure moving eastward into Arizona, with an axis running from Southern California back northeast into North Dakota. This system does not have a lot of moisture with it, so there are no rain chances; however, it will increase northwesterly winds a bit later this morning into the afternoon hours. We are currently forecasting these winds to be in the 15-25mph range, with higher gusts possible. With these winds expected over a large portion of Western Arizona and Southeast California, dust will likely be produced locally and transported into the region from the north/northwest, so we have raised PM-10 into the Moderate AQI category for today.

As the system moves east tonight into tomorrow, high pressure will quickly build back over the region through Friday. As this transition happens, expect breezes again tomorrow, but they will not be as strong as today. This area of high pressure will also result in afternoon highs rising back into the mid to upper 70s by Thursday into Friday.

As for air quality, as noted above, the big story will be the possibility of blowing dust today. Tomorrow through the rest of the forecast period, expecting ozone, PM-10, and PM-2.5 to be in the Good AQI category.

Make it a great Monday!
