FORECAST SUMMARY: Monday, March 7th, 2022, through Monday, March 14th, 2022

PM-2.5: 24-hour average Fine Particulate levels will range between Good and Moderate during the forecast period.

FORECAST DISCUSSION:

A storm system Monday brought snow accumulations to much of the state, with some mixed precipitation in southern locations. Generally quiet conditions are expected Tuesday through Thursday before another system brings precipitation back in the forecast for the end of the week. Temperatures will be at, or close to, seasonable levels through much of the week; however, colder air filters in on Saturday as the Friday system brings a stronger cold front through.

As for fine particulate, lighter winds early Monday pick up from the northwest during the day as snow comes to an end. Fine particulate levels will be mostly Good Monday, but high pressure sliding across the Ohio River Valley brings weaker and then southwesterly winds Tuesday. Warmer conditions combined with increased moisture from snow melt may allow for some Moderate fine particulate readings. A storm system north of Lake Superior brings a “dry” front north to south Wednesday generating northerly winds across the northern and central portions of the state. This boundary seems to stall just south of Michigan until a stronger storm develops and tracks northeast into our region Friday. A mix of Good and Moderate fine particulate is expected mid-week until the storm passes Saturday.

EXTENDED FORECAST:

Extended forecast models show strong northwest winds Saturday bringing in cold air. High pressure slides in quickly for Sunday with another system tracking through as early as Monday. The weekend will begin with Good fine particulate while a mix of Good and Moderates may develop early next week.
