FORECAST SUMMARY: Monday, January 23, 2023, through Monday, January 30, 2023
PM-2.5: 24-hour average Fine Particulate will range mostly Good with only scattered Moderate readings through the forecast period.
FORECAST DISCUSSION:
Northern portions of the state may see some snow Monday into Tuesday, but a quiet start to the week is expected across the rest of the state. A more active pattern develops statewide by mid-week as a winter storm tracks from Texas to the Ohio Valley. Snow makes its way into Michigan Wednesday with highest accumulations in southeastern areas and less further northwest. This is the first of three storms that bring chances for snow through the forecast period. Current models show another system Friday into early Saturday and a third early next week. Cooler temperatures will be brought in behind each as highs trend cooler into the weekend.
As for air quality, mostly Good fine particulate is expected Monday and Tuesday aside from a scattered low-Moderate in southern locations. Good levels can be expected Wednesday into Thursday as gusty easterly winds develop ahead of the storm, switching to northwesterly as it pulls away. Weak high pressure building in late Thursday/early Friday could allow for some low-Moderate fine particulate Friday with weaker winds turning southwesterly; however, any build up will improve to Good Saturday as northerly winds develop behind the late week storm.
EXTENDED FORECAST:
Extended models show another storm passing southeast of the state Sunday. If this system remains on track, fine particulate should remain generally Good through early next week.
