Forecast Discussion:

Water vapor satellite this morning shows a large area of high pressure off the West Coast of the United States. This weather feature will be the primary driver of our weather through at least Thursday with mostly clear skies, calm winds, and above-average high temperatures.

By late Thursday into Friday, a trough will move by the state to the north and east as the high centers itself over the southern portion of Nevada. This will open the door for some breezy easterly winds. Temperatures are also forecast to lower a bit on Friday before rising once again this weekend.

As for air quality, forecasting both PM10 and ozone to be in the Good AQI category through the forecast period.
