29. Some light snow spreading across the region late Thursday.
Despite what it says in the previous article, northern Wisconsin has not been receiving the record snowfall... the southern part has. While we are not in a drought up here, we could use some more snow.
It won't be a snowstorm, but we will probably see a clipper-type system move towards the western Great Lakes through the end of the week. It won't be strong, nor have abundant moisture at its disposal, but it'll have to do. Also, in the negative column, it doesn't seem to want to hang around a visit for a while.
By the numbers:
The HPC's Quantitative Precipitation Forecast (QPF) shows between 0.15 and 0.35 inches of liquid for the region from this system. With a snow/liquid ratio of 10:1 that produces 1.5 to 3.5 inches of snow, while a 15:1 ratio gives us 2.25 to 5.25 inches. One to three inches seems most reasonable for northern Wisconsin, while NWS Duluth thinks the Arrowhead of Minnesota may see a tad bit more.
The map (to the left) is the 0z run of the GFS that shows surface pressure and precipitation at 54 hours... 0:00 early Friday morning (29th). A broad surface low is shown from Ontario down into Minnesota with a shield of precipitation out ahead of it. The freezing line runs from Nebraska down to Kentucky so we will only be looking at a snow event. Also, there are no other major storms painted across the Lower 48.
