Tracking snow Wednesday, and heavier snow Friday!

Remaining Ad Time Ad - 00:00

We see some partial clearing tonight and temperatures dip around midnight to the upper single digits and low to mid teens. Expect mostly cloudy with a few areas around the Borderland seeing partly cloudy skies. Winds are out of the northwest at 4-8mph. A weak ridge in the jet stream keeps us dry.

Snow begins Wednesday morning at around 7am for the areas around the Twin Ports. We have an earlier start time for the snow further to the southwest of Duluth. Expect a 70% chance of snow throughout the day as a low pressure system moves over the Great Lake States and we have a trough in the jet stream aloft supporting the low. With the low moving through our winds will pick up a bit out of the northwest at 5-15mph.

Snowfall amounts will be around 1-3” with some locations around the snowbelt of Iron and Gogebic Counties in the 2-5” range. Expect a swath of around 2-4” in Itasca and NW St. Louis Counties.

High pressure builds on Thursday and we clear up and cool down! Morning lows are near -10 and highs reach 3 with sunny skies. A high pressure system at 1044mb sits right over us (really strong).

Our huge high moves east and a large low pushes east as well into South Dakota by Friday afternoon. Friday morning will be mostly clear and cold with temps near -6. By the afternoon southern flow increases and warms us up to 21. There’s a 70% chance of snow by the afternoon as the low nears. As of now it looks to begin around 5-7pm for the Twin Ports.

The low sits on the border of Minnesota and Iowa overnight and continues snow as lows are much milder, near 16. The snow keeps falling throughout most of Saturday and our winds pick up out of the northwest at 15-25mph as the low pushes over Lake Huron at around 992mb. By the evening hours the snow starts to lighten up. Highs I the afternoon are in the upper teens.

This system is still too far out to make a snow map but what I can say is that there’s a 60% chance of more than 6 inches. Up the North Shore it’s a 70% chance. The two models that go out that far show around 7-10”. This system will be our next big storm, so keep your eyes on the forecast!

Sunday we clear up, except for the South Shore where lake effect snow will continue. Morning lows are down to -6 and highs reach 6. Aside from the South Shore, the rest of the region can expect mostly sunny skies.
