Today’s Video:
Good Tuesday morning everyone. Longer video today to cover the numerous rounds of accumulating snow over the next 72 hours. The first of which is ongoing in Southern Minnesota right now with a narrow band of moderate to heavy snowfall at times spanning from Brookings, SD to Minneapolis, MN. Here’s a look at the current radar.
Upward motion in the snow growth zone is aiding in the development of these bands of snow. Data has overall done a poor job honing in on this potential, but the HRRR seems to have a decent idea as it puts down a band of 2-4″ of snow into this afternoon. Based on some weak frontogenesis, isolated amounts of 3-6″ are not off the table with this band into this afternoon. Note, snow showers will also develop in North Dakotas and Western South Dakota as we work into this afternoon and evening. These snow showers will likely be somewhat sporadic, especially at first but amounts of 1-2″, isolated 3″ are certainly possible from W. SD, ND and N. MN. Another band of snow will develop this afternoon and evening in SE Minnesota with a narrow band of 6-9″ of snow possible in SE Minnesota. Note, the model may be a tad underdone in areas SE of Rochester where data is trying to hint at some freezing rain. A light glaze is possible, but we believe the wave to be primarily snow.
As we work into tomorrow morning more snow will develop from SW South Dakota and push northeast with multiple waves of moderate to heavy accumulating snow likely into Thursday night before this system pushes out of the area by Friday morning. Given the long-duration of this event and high snow ratios, widespread totals of 6″+ are likely across the area. Some weak frontogenesis is possible and areas that see this can likely get over 12″ of snow. 
Temperatures will generally remain in the single digits or below zero for the Dakotas and Northern Minnesota with portions of Central/Southern Minnesota getting into the teens. Overall snow to liquid ratios will be very high which will allow for a very fluffy snow that can easily blow and drift around. Given this risk and wind gusts to 40 MPH on Thursday, blowing and drifting snow will likely be an issue Thursday with blizzard conditions possible at times:
Beyond this system, we’ll need to watch a system on Sunday, but there remain a good deal of discrepancies on data at this point.
