Strong Winter Storm Targets Northern Plains and Upper Midwest
One look at Weather Underground's Severe Weather Map shows where the active weather will be happening on Tuesday. While various Winter Weather Advisories will be affect in parts of the West, hardest hit area of the country will be the Northern Plains and Upper Midwest. An intense storm will race out of the Rocky Mountains and through Nebraska before moving into the Dakotas where it will join significantly cold air. This is a common track for Winter storm as they often increase in strength as they move into the Plains of Colorado and New Mexico.
Various Winter advisories and warnings, including Blizzard Warnings, Winter Storm Warnings, and Winter Weather Advisories are posted from eastern Wyoming through Wisconsin and western Michigan in preparation of this storm. The first to get hit will be the western Plains and Rocky Mountains Tuesday morning and afternoon. Upwards of 2 feet of new snow is possible in the San Juan Mountains of Colorado from this initial period of the storm. By late Tuesday and into Wednesday, snow will begin coming down in the Dakotas and Minnesota. Another two feet of snow is possible in the hardest hit areas of Minnesota and North Dakota, but most areas will receive much less than that.
The secondary effect of this storm wil be the strong winds it will produce. Wind gusts greater than 30 mph will whip the newly-fallen snow into a blizzard in some places, greatly lowering visibility and creating hazardous conditions.
This is a bit out of the norm for this Winter. Much of the Winter has been dominate by fairly weak storms will little jet stream support, void of cold Arctic air, and missing any sub-tropical moisture. This storm, at least, will provide a good portion of the country will significant snow.
