The constant barrage of storms continues as we track yet another storm system bringing light to moderate snow in portions of the Northern Tier beginning Sunday. An area of low pressure moving into the Northwest coast on Saturday will make its way east of the Rocky Mountains and into the Northern Plains on Sunday. By Monday, however, the low pressure will weaken and transform into an open wave of low pressure. Therefore, this storm shouldn’t be very impactful for most locations.

So, impacts from this storm will begin on Sunday as a quick-moving shield of light to moderate snow moves from eastern Montana, much of North Dakota, eastern South Dakota, Nebraska, and Kansas during the morning hours to the Midwest, including much of Minnesota, Iowa, and northern Missouri during the afternoon. Back toward portions of the Dakotas and eastern Montana, it will be a snow day with a light snow snow lasting through much of the day. A lot of this snow will accumulate too given the intensity of this snow where snowfall rates in some areas will get up to around 1 inch per hour. A very cold air mass has been in place throughout the week as well, and the cold air will continue through the duration of this storm.

Then into the overnight hours of Sunday, the snow will continue into portions of Minnesota, Iowa, and northern Missouri while moving into western and southern Wisconsin, much of Illinois, Indiana, Ohio, southern Lower Michigan, eastern Kentucky, and the central Appalachians. By this point, much of this snow will be light. Many of these areas, including major cities like Chicago, will experience accumulating snow for the most part given the freezing temperatures.

As we get into Monday, this storm will practically dissipate. Occasional rain and snow showers will remain in place through portions of the Northern Plains, Midwest, and the central Appalachians, but the accumulation of the snow is unlikely.

Those rain and snow showers will then move into the Northeast on Tuesday, and by this point we’ll be tracking a developing coastal storm off the Carolina coast. The upper-level pattern will be somewhat favorable for a rapidly-strengthening storm while tracking toward the Northeast coast, but details in terms of impacts — if any — are unknown at this time. Continue to monitor the forecast because there is the chance for snow and/or rain with this next storm system, especially in New England.
