FORECAST DISCUSSION:
Friday February 7th is here, and a good number of Michiganders woke up to clearing skies and a chilly sunrise this Friday morning. A High-pressure system currently sitting just to our southwest is providing this welcomed change of pace. This High-pressure system will slide to the east throughout the day and will keep the door open for another system, a Low-pressure, to move into the region Saturday morning. This system will provide a flurry of precipitation to the Great Lakes state throughout Saturday with multiple inches of snow expected north of the I-69 interstate. Areas south of I-69 will still see an inch or two, but mixed precipitation will cut down on those snow totals. The system tomorrow will be a quick mover as come Sunday, we are back under High-pressure and relatively calm conditions in terms of snow showers. Temperature-wise, with the encroaching Low-pressure and snow showers, winds will shift to more northwesterly flow which will cool down much of northern Michigan. Southern Michigan will be seasonably cool in the twenties with the upper peninsula even colder in the low teens to single digits come Sunday.
Ahead of the pressure system and frontal boundary moving across the state tomorrow, we will see light winds in the morning which may see an increase in PM-2.5 concentrations in more populated areas like Metro Detroit and Grand Rapids. Once the frontal boundary moves through, any concentrations will be cleaned out and with the aid of northwesterly winds, Sunday will see clean, Good air quality. Monday looks to be a continuation of Sunday with light winds and slightly more westerly flow, as temperatures hang around the teens to low twenties.
EXTENDED FORECAST:
Next week looks to have northerly flow to start off the week, so air quality is looking to remain in the Good range.
