FORECAST SUMMARY: Friday February 28th 2025 through Monday March 3rd 2025
PM-2.5:
PM-2.5 concentrations are expected to be in the Good range.
FORECAST DISCUSSION:
We round off the month of February with a melting snowpack in southern Michigan, and winter weather in northern Michigan and throughout the upper peninsula. A relatively strong Low-pressure system is traversing the state as one reads this forecast with winter storm warnings and winter weather advisories impacting northern Michigan. Accompanying these winter advisories and warnings are wind advisories peppering the Great Lakes state as the aforementioned Low-pressure system tightens the pressure gradient in the state, thus creating windy conditions throughout this afternoon. This system will be off to the east come Saturday morning leaving a fresh snowpack to those in the north, and light winds and cold temperatures for all Michiganders. In the wake of the Low-pressure system, winds shift to more northwesterly flow which will bring arctic air back into Michigan for Saturday and into Sunday. Although cold, the arctic airmass will be relatively stable and quiet, with no additional snow or wind for the remainder of the weekend. Come Sunday afternoon, the majority of Michiganders reach the freezing mark with an upward trajectory of temperatures on the horizon for the week ahead.
Windy and cold conditions will help keep PM-2.5 concentrations at bay for the weekend ahead with clean, northerly winds aiding that as well. We should not see an increase in PM-2.5 concentrations until early next week when temperatures increase into the 40s.
EXTENDED FORECAST:
Similar to this week, we see an increase in temperatures early next week with the upper-40s returning. Overall air quality should remain in the Good range.
