1/25/2021 Forecast Update
FORECAST SUMMARY:
Monday, January 25th, 2021 through Monday, February 1st, 2021
PM-2.5: 24-hour average Fine Particulate concentrations will be a mix of Good and Moderate during through the forecast period.
FORECAST DISCUSSION:
So far, this has been a relatively dry winter with snowfall amounts well below average. We should make up a little ground on that, Monday night and Tuesday, as a low-pressure cell passes to our south across the upper Ohio Valley. While not a major event, we can still expect a few inches of new snow between the I-94 and I-96 corridor.
As of Monday morning, we are seeing Moderate levels of PM-2.5 across the Lower Peninsula. That should persist through Monday with remnants of these Moderates confined to Southeast Michigan on Tuesday.
Wednesday and Thursday should be mostly Good under a northerly component wind pattern. A high-pressure ridge passes over the region, Friday, which could return Moderate conditions to some areas of the State. These conditions would likely persist until Sunday when a low-pressure cell passes through the State. West to northwest winds will persist from Sunday afternoon through early next week along with Good Air Quality.
EXTENDED FORECAST:
Air Quality should be mostly Good going into next week.
