FORECAST SUMMARY: Friday, September 6, 2024, through Monday, September 9, 2024
OZONE:
8-Hour average Ozone concentrations will be Good (AQI Green).
PM-2.5:
24-hour average Fine Particulate concentrations are also expected to be mostly Good (AQI Green).
FORECAST DISCUSSION:
Following the passage of a Thursday night cold front, the warmer temperatures of the past few days will be replaced with cooler, dry Canadian air. Weekend temperatures will reach the high 60’s with dry dew points in 40’s. Air Quality will be Good through the weekend.
Summer is not entirely gone, though. By Monday, temperatures will rebound into the upper 70’s and by Tuesday, back into the 80’s. Most of the second half of the week will experience temperatures in the upper 80’s. While the chances of elevated ozone decrease as autumn nears, under the right conditions, it can still occur. As such, we will be keeping an eye on potential developments as the week progresses.
Wildfires continue in the western states and provinces. All smoke models agree that we should not see any impact at ground level.
EXTENDED FORECAST:
Air Quality is expected to remain Good going into the upcoming work week.
