FORECAST SUMMARY: Monday March 27th, 2023, through Monday April 3rd, 2023

PM-2.5:

PM-2.5 concentrations are expected to range from Good to low-Moderate. 

FORECAST DISCUSSION:

The month of March ends with temperatures nearing seasonal averages for most of Michigan with consistent seasonal norms as we get into April.

For this week, we start out today, Monday, with northerly flow providing cooler temperatures in the northern parts of the state. Winds shift throughout the day on Tuesday to more WSW with more chances of sunshine than today, Monday. A change in airmass comes through on Wednesday with a Low-pressure system and associated cold front. This will drop temperatures back below freezing for much of the state, but temperatures rebound on Thursday with a return to upper-30s and 40s. Southerly flow returns once the Low-pressure exits the area and gives way to High-pressure to our southeast. This lasts through Friday until a quick-hitting cold front comes through on Saturday providing mixed precipitation throughout the state and dropping temperatures slightly. This airmass sticks around through Sunday until a warm front appears to eclipse Michigan next Monday which may push some areas into the 60s.

For air quality, with the help of changing airmasses, PM-2.5 concentrations do not look like they will be a concern for this forecast period. Overall PM-2.5 concentrations will be Good with a chance of a few hours of Moderate in the morning hours of more populated areas.

EXTENDED FORECAST:

As stated above, a warm front appears to come through to start off next week. Overall air quality will remain Good.
