Winter Storm Set to Blast Through the Midwest, Bringing Snow and Arctic Air

snow accumulation

Another winter storm, fresh off the heels of a weekend wintry blast, is set to impact parts of the Upper Midwest and the Great Lakes region. In addition to the potential for snow, bitterly cold temperatures are forecast to blast as far south as North Carolina’s Piedmont.

First things, first, let’s talk about the snow potential:

watchs and warnigns

As of mid-morning, on Monday, snow was on-going over parts of the northern Intermountain West and parts of the Dakotas. This is all in association with a small, but potent, upper-level impulse swinging out of Alberta. Significant snowfall is possible for a large swath of eastern Washington, the Idaho Panhandle and much of western Montana. Winter Storm warnings are in effect for those areas until late-morning on Tuesday for many of these areas. Snow fall total will range from one to two feet in the mountains of Montana to just a few inches in some of the valleys. Some sections of northern Washington could also get some , but freezing rain will also be a serious concern.

Further east, as the afternoon progresses, the upper-level disturbance will push into the Dakotas and snow coverage will increase in area and intensity. Winter weather advisories and winter storm watches and warnings extend from the Dakotas into Ohio.

The highest snowfall totals will be from the southeastern South Dakota to northwestern Illinois. In general, six to eight inches of snow are expected in this region. Elsewhere, four to six inches of snow are possible from Chicago to Indianapolis to Columbus, Ohio.

Travel by car and air will likely be significantly impacted through Tuesday. Stay weather aware and drive with extreme caution though mid-week.

lows

The other part of this wintry one-two punch is a brief, but brutally cold shot of arctic air that will spill south.

Early Thursday morning, temperatures in the single digits could reach as far south as western fringes of the North Carolina Piedmont plateau. While that’s very cold, much of the Ohio River Valley and Upper Midwest will see temperatures plummet below zero. Cities like Columbus, Ohio, Indianapolis and Chicago are likely to record temperatures between -10 and -5 degrees.

This is a developing storm and the forecast will be subject to change in the coming hours. but WeatherNation meteorologists will keep you up-to-date on-air and online.
