Forecast Summary:
Monday, February 7th, 2022, through Monday, February 14th, 2022
PM-2.5: Concentrations are expected to be in the low-mid Moderate range to begin the week for much of central and southern Michigan but return to Good concentrations in the latter half of the week.
FORECAST DISCUSSION:
The start of this week seems to be rather similar in terms of atmospheric conditions, compared to the beginning of last week. There are two High-pressure systems, one to the south and one to the north, which will keep conditions somewhat stagnant to begin the week. With temperatures expected to be above freezing for the next few days and a pretty thick snowpack in some areas, low-level inversions have and will continue to form and trap particulates close to the ground. Concentrations are not expected to reach USG levels for 24-hour averages, but enough to sustain mid-Moderate levels. Midweek, a Low-pressure system and associated cold front make its way through the Great Lakes region and helps to clean out the buildup of particulate concentrations. Particulate concentrations will return to mostly Good once the system passes through and should remain Good for the remainder of the forecast period.
Temperature highs hang around the low-mid 20s Fahrenheit for Thursday before another clipper system comes through Friday. Light snow accumulations are expected with this system. The combination of the two systems coming through later this week, will keep particulate concentrations at bay and eliminate any buildup that occurs. Once the clipper system exits the region Friday night, the weekend looks to be rather quiet in terms of overall weather and concentrations.
EXTENDED FORECAST:
Concentrations for early next week look to remain mostly Good.
