FORECAST SUMMARY: Monday, August 29th, 2022, through Thursday, September 1st, 2022

OZONE: : 8-hour average Ozone concentrations are expected to range mostly Good to low-Moderate towards the end of the forecast period.

PM-2.5:  24-hour average Fine Particulate will range Good to low-Moderate.

FORECAST DISCUSSION

A cold front passing west to east through the state Monday will bring showers, storms, and a west/northwesterly wind in its wake. Conditions dry out Tuesday with high pressure producing seasonable conditions through midweek. High pressure is positioned east of the state by Friday with high temperatures warming around 80 degrees.

As for air quality, clouds and storms will keep air quality Good Monday. This Good trend should continue into midweek thanks to a westerly/northwesterly flow at the surface and upper levels, coupled with cooler/seasonable temperatures. By Friday, southerly winds develop, and surface and upper-level temperatures increase. Without an airmass change, rises in ozone and/or fine particulate are likely. At this time readings higher than Moderate are not expected; however, the forecast will be evaluated again Thursday to get a better handle on air quality conditions for Friday into the coming Holiday weekend.

EXTENDED FORECAST:

Extended models show a weak boundary passing later Friday/early Saturday; however, not much precipitation is associated with the system. At this time a generally dry weekend is anticipated, and warming temperatures could allow for increased pollution.
