Good afternoon! WINTER STORM WATCHES are hoisted for Berrien, Cass, St. Joe, and Branch counties starting 7 PM Saturday evening and lasting until Sunday night. There's high confidence in Sunday snowfall, but where the heaviest snow will fall is still up for debate. Let's be clear, this system has been modeled poorly since the beginning of this week. Our official forecast includes a range of 4" to 8+" from Allegan to Charlotte and southward to the MI/IN line. The + sign gives us flexibility for higher totals, especially south of I-94. Because the track of the storm is in flux, it's important to stay with us tonight and all weekend long. Models will converge on a storm track, which allows fine tuning of snowfall amounts and more importantly, the heaviest snow.
Until then, your Friday afternoon and evening are comparatively quiet. Clouds with a little sun and middle 20s are the rhythm of your evening commute. Tonight is a bit unusual in that lows happen this evening, middle teens, before temperatures rise to near 20 by daybreak Saturday. Saturday brings plenty of clouds and better temperatures. Highs reach the freezing mark while a few snow showers dot the lower Peninsula. The best chance at seeing them is north of Kalamazoo.
Light snow develops Saturday evening, mainly closer to midnight, and becomes steadier, heavier by daybreak Sunday. Snow, heavy at times, is your Sunday weather, especially south of I-96. While the heaviest snowfall is a huge story, we're arguing for 2" to 5+" in and near Grand Rapids, which is significant. Blowing and drifting are a big part of your weather on northeast winds of 15 to 25 mph. Snow should end early Monday, and if clearing happens quickly enough, lows may dip below zero Monday morning.
Monday is downright frigid and mainly dry, important for cleanup from Sunday's snow. Light snow arises Tuesday with even more snow in line for Wednesday. Arctic air would return Thursday in a drier pattern. Have a great Friday night and weekend! Check in with Chief Meteorologist Keith Thompson at the regular time of 5 PM! He'll have a fresh look at expected snowfall for Sunday and your entire weekend forecast.
