One rule of Minnesota weather? If the cold air is here, the snow can’t be far behind.
Case in point Friday morning. A little upper air wave snuck through the forecast models grid largely undetected. The result? A few minutes of quality snow showers that got our attention this morning.
Saturday brings a stronger and more widespread system to central and northern Minnesota.
Forecast models still drag a cold low-pressure system across Minnesota with a band of snow north of the low center.
Here’s the Canadian model solution.
Expect several hours of snow across central and northern Minnesota Saturday. The Twin Cities rides the southern edge of the system, and may see a mix of a few rain showers and a few flakes.
How much snow?
Friday’s forecast models have eased off a bit on the notion of higher snowfall totals some suggested Thursday.
For the Red River Valley and northwest Minnesota, general 2 to 4-inch totals with some local 5-inch totals still look likely Saturday.
Including the cities of Crookston, East Grand Forks, Ada, Twin Valley, Halstad, Warren, Stephen, Argyle, Newfolden, Middle River, Grygla, Red Lake, Redby, Ponemah, Thief River Falls, Red Lake Falls, Fosston, Fertile, McIntosh, Erskine, Bagley, Clearbrook, Bemidji, Mahnomen, Naytahwaush, Waubun, Alida, Ebro, Lake Itasca, Long Lost Lake, Lower Rice Lake, Roy Lake, and Upper Rice Lake
