FORECAST SUMMARY: Monday, March 6, 2023, through Monday, March 13, 2023

PM-2.5:
PM-2.5: 24-hour average Fine Particulate will range primarily Good with only small chances for low Moderate through the forecast period.

FORECAST DISCUSSION:

A low-pressure area tracking just south of the state Monday brings snow across central/northern locations and rain chances further south. High pressure then settles in producing dry and cool conditions for a few days. The next system brings mostly snow chances back in the forecast Friday while rain may mix in across southern areas.

As for air quality, Good to low-end Moderate fine particulate levels are anticipated Monday as the low passes to our south. The dominating weather feature then turns to high pressure positioned northwest/north of the state through midweek. Expect northerly winds and mostly Good fine particulate through Thursday. By Friday, easterly winds ahead of the next storm could allow for scattered low-Moderate fine particulate levels, otherwise, readings remain Good.

EXTENDED FORECAST:

Extended models show high pressure moving behind the Friday system with dry conditions Saturday into Sunday. Some models are showing the next weather feature bringing precipitation back late Sunday into Monday. Without a stagnant period or warm-up expected, fine particulate should remain mostly Good into early next week.
