As we transition into a warmer period, we get to move back into a more unsettled pattern. The jet stream, or that river of air at the top levels of the atmosphere that is the steering current for storms, will jaunt back north and sit overhead through the weekend. This will bring two quick waves to the area.
Neither one all that strong or large, but will bring us 2 chances for snow by Monday morning.
The first of these waves will stay in mostly southern Minnesota with any and all accumulation expected south of the I-94 corridor. The timing looks pretty quick with a 6 hour window for the snow to fall Saturday afternoon and early evening.
Here is a look at the potential snowfall for this first clipper from 2 different forecast models.
The second wave looks like it may have a little more moisture, at least it does right now, which could lead to slightly higher totals in some areas.
But precipitation type may come into play for central and southern Minnesota as those numbers will be awfully close to freezing at the lowest levels of the atmosphere which could switch snow over to a wintry mix of sleet and freezing rain. Right now though, most computer models show the dominant precipitation type as snow.
Here are 2 separate models for the second storm expected Sunday night and early Monday.
As a note, this is just a 12 hour period of snow accumulation shown from Sunday evening through Monday morning. Not a storm of the century by any means. However, with the metro on the far western fringe of this expected snow band, one small shift could mean the difference between getting nothing, or getting 3 or 4 inches.
Combined, these 2 systems could bring much of the area a solid 2 to 6 inches of snow from west to east and just add to the already high snow pack in many areas.
Here is a forecast from the Weather Prediction Center (WPC). The following 2 images show the probability of getting at least 2 inches and at least 4 inches of snow through Monday at noon.
Notice that almost the entire state has at least a 70% chance of 2 inches of snow, including the metro. The 4 inch category is mainly compacted to Wisconsin areas but the metro still has a 50%-70% chance.
I know it's not ideal with the milder temperatures coming with more snow, but I think a lot of us would rather see that at this point than more subzero numbers.
