Significant Snow Expected Monday into Tuesday

Heaviest Snow in Southwest Minnesota

A fast moving low pressure system is beginning to make its way eastward and as it does, it will bring significant snow fall in the short time that it is in South Dakota and another round of Arctic air for next week.

A low pressure system is developing off to our west and will be moving through the state very quickly tomorrow. The warm front will influence the state first, warming our temperature up into the teens along the Missouri River, warmer near Valentine and the low single digits in the northeast. The warm front not only brings warmth, but also moisture as well. With the temperatures below freezing, that moisture will fall as snow, starting in the early afternoon and lasting until the late evening hours on Monday, into early morning hours on Tuesday.

The low pressure system will move through quickly but not before dropping nearly a half a foot of snow across portions of the state. From near Aberdeen southeast into portions of northwest Iowa and southwest Minnesota, 4-6” of snow can be expected. Farther into northwest Iowa, snow fall accumulations will surpass 6”. Due to the significant snow fall, a winter storm warning has been issued starting at NOON on Monday until MIDNIGHT on Monday. Not only will the snow accumulations be significant, but southeast winds will be between 15-25 MPH which will cause whiteout conditions on roadways. If you don’t have to be on the roads, don’t. If you do, drive slowly, pump breaks and allow yourself extra time to get to your destination.

The cold front, on the back side of the low, will swing through the state quickly bring another round of Arctic air to South Dakota. The Arctic air will be ahead of a strong high pressure system which will transport the cold air south Tuesday into Wednesday, along with opening skies to mostly clear conditions midweek. High temperatures will be only in the single digits for Tuesday underneath partly cloudy skies then temperatures will drop even further for a high temperature of -2° with mostly clear skies on Wednesday.

Stay warm and safe over the next couple days. If you don’t have to be on the roads or outside, don’t. If you do, make sure you’re not only dressing warmly but make sure you are pumping breaks, allowing adequate distance between yourself and the next vehicle as well as extra time due to reduced visibilities/deteriorating road conditions.
