FORECAST SUMMARY: Monday, September 23, 2024, through Friday, September 27, 2024
OZONE:
Ozone concentrations will be Good (AQI Green)..
PM-2.5:
PM-2.5 concentrations are also expected to be mostly Good (AQI Green).
FORECAST DISCUSSION:
After a spell of warm, dry weather, the surface low that brought welcomed rain to the area is now over the eastern Great Lakes. While dry weather is anticipated on Monday, a surface low lifts in from the southern Mississippi River Valley, tonight, bringing in showers and thunderstorms by early Tuesday and will lingers most of the day. Air Quality is expected to be Good.
I anticipate a drying out during Wednesday with high pressure ridging building into the Midwest that will produce dry and sunny conditions through Friday. Above normal temperatures in the mid to upper 70’s are anticipated with dewpoints in the 50’s making for comfortable conditions. Air Quality should remain Good.
Plenty of uncertainty with the upcoming weekend. Models are showing a sizable tropical storm in the Gulf moving north toward the Florida panhandle. That could eventually get caught up with the circulation of an upper lever low in the Arkansas/Texas area that is forecast to slowly meander towards the Great Lakes area. That could encourage what is left of the weakening tropical system to merge and move north through the Tennessee and Ohio Valleys. Models are currently keeping precipitation well to our south but changes in the tracking could produce some shower activity in Michigan.
EXTENDED FORECAST:
Air Quality is expected to remain Good going into the upcoming weekend.
