FORECAST SUMMARY: Friday, September 2nd, 2022, through Tuesday, September 6th, 2022
OZONE: :8-hour average Ozone concentrations are expected to range between Good to Moderate.
PM-2.5: 24-hour average Fine Particulate will range from Good and Moderate.
FORECAST DISCUSSION
Surface high pressure holds on for most of Friday, but a frontal boundary is forecast to track northwest to southeast through the state later Friday into Saturday. Precipitation with this boundary will be scattered in nature so Saturday will not be a washout. Cooler temperatures move in Sunday and Monday as high pressure settles in from the northwest.
As for air quality, warm conditions at the surface and upper levels Friday and Saturday make increased ozone a possibility; however, cloud cover in more pronounced which will hamper development. Generally Moderate ozone is anticipated both days. Warmer conditions and southerly winds ahead of the frontal boundary could increase fine particulate into the Moderate range as well. Northerly winds Sunday into the Labor Day holiday should keep air quality mostly Good.
EXTENDED FORECAST:
Extended models show generally dry conditions into Tuesday with temperatures increasing on southerly winds. While significant increases in pollution is not anticipated, ozone and/or fine particulate may rise back into the Moderate range.
