Forecast Discussion:

Satellite this morning shows a trough of low pressure moving into the state from west to east. Some light rain is falling around the Valley this morning, but that's about all we are expecting rain-wise. With that said, there is a better chance of rain and snow across the High Country.

Even though we won't see much rain, we will see breezes in the 15-20mph range today, along with high temperatures only rising into the mid-60s!

This storm will quickly move east of the state tomorrow before another weak and dry storm system moves into the region late Sunday into Monday. This will increase breezes and high clouds but no chance of rain.

High pressure will be the main weather driver late Monday through at least the middle of next week, which will mean a return to calm winds and warming temperatures. High temperatures by Wednesday and Thursday will be nearing the 90-degree mark.

As for air quality, with the active weather today, forecasting ozone to stay in the Good AQI category; however, as lighter winds move into the picture tomorrow and again Tuesday, ozone is forecast to rise back into the Moderate AQI category. PM-10 and PM-2.5 are both forecast to remain in the Good AQI category through the forecast period.

Have a great weekend!
