FORECAST SUMMARY: MondAY, November 20, 2023, through FRIDAU, November 24, 2023

PM-2.5:  PM-2.5 concentrations are expected to be in the Good to low-Moderate range.

FORECAST DISCUSSION:

Happy Thanksgiving to all those who celebrate as we, Michiganders, dive back into seasonably normal temperatures this week after a week of above normal temperatures and overall beautiful weather. Today, Monday, will see temperatures in the upper 30s with relatively cloudy skies for most of the state. A low-pressure system approaches us late tonight through tomorrow which will bring rain for the majority of the state with some mixed precipitation the more north one travels. This precipitation will last essentially all day, but we dry out as Wednesday evening approaches. Once the low-pressure exits to the east early Wednesday morning, a cold front follows behind it which will keep surface temperatures cool and the skies relatively cloudy. Turkey Day (Thursday) will see the continuation of Wednesday weather with mostly cloudy skies and surface temperatures scattered from low-30s to low-40s throughout the state. Northerly winds will dominate this week with some easterly and westerly component mixed in, but the northerly winds will be the reason for a return to seasonably normal temperatures. Friday will see cooler temperatures and cloudier conditions to round off the work week.

Due to the northerly winds, and relatively consistent wind speeds, PM-2.5 concentrations should not be an issue this week. As always, there is a chance of concentration build up in the morning hours due to stagnant conditions, but those conditions will dissipate as the days carry on. Overall PM-2.5 air quality will be on the Good range.

EXTENDED FORECAST:

This weekend presents us with more of the same from the work week with slightly cooler temperatures throughout. Overall air quality will remain Good.
