FORECAST SUMMARY: Monday, October 23rd, 2023, through Friday, October 27th, 2023

Ozone: 8-hour average ozone concentrations are expected to be Good.

PM-2.5:  24-hour average Fine Particulate concentrations are also expected to be mostly Good to Low Moderate.

FORECAST DISCUSSION:

After a chilly start to Monday morning, temperatures are expected to rebound to above average for most of the week. The forecast area will be in a warm air sector and temperatures for Tuesday are expected to be in the low 70’s before settling into the mid-60’s for the rest of the work week.

While a few showers may pop up during Monday and early Tuesday, most areas should be dry. This will be welcome news for harvesters who have been sidelined with wet weather and muddy fields. Unfortunately, by Wednesday, wet weather moves back into the region with the possibilities of significant precipitation for the rest of the week.

The warmer weather should last into the weekend before a cold front moves through and temperatures drop back into the 50’s.

Air Quality during the week should be mostly Good. Ozone, at this late date, is no longer an issue. Fine particulates should be mostly Good but the abundance of moisture with warmer temperatures may produce some Low Moderate readings, especially in the more southern and more populated areas.

Fortunately, wildfire smoke season appears to be mostly behind us as most of the large Canadian wildfires are now contained to the western and northwestern most provinces.

EXTENDED FORECAST:

Air Quality should be generally Good to Low Moderate to start the weekend.
