Forecast Discussion:

Today (Tuesday), the low-pressure system in the northern part of the U.S will dip down into Nevada. This will result in a jet stream forming right over our state and bring breezy west-southwest winds this afternoon. With these stronger wind conditions, a few hours of elevated PM10 (dust) levels can be expected. PM2.5 (smoke) will follow a similar trend with these winds but not to the same extent of PM10.

We will have another breezy afternoon Wednesday as a second jet stream rolls across our state. The timeframe will be similar to today (afternoon/overnight hours) so expect elevated dust levels tomorrow too. We are looking to decrease in temperature as the trough passes overhead. The Mid to upper 80s is on the forecast for the remaining workweek.

Glancing at the weekend, another round of stronger winds is looking to be the story. This time they will be out of the north and last throughout Saturday and Sunday. This wind direction can lend a hand to helping particulates, but depending on how much dust is out there, this story could change. We'll keep an eye on the weekend forecast as we get closer to that time.

Overall, breezy afternoon winds today and tomorrow, resulting in Moderate Air Quality Index (AQI) for PM10 and PM2.5 both days. The good ventilation is helping ozone remain in the Good AQI range along with no dominating high-pressure system over our region.
