...Accumulating Snows Are Expected Across The North Central U.S....
...Moderate To Heavy Precipitation Will Begin Moving Into Northern
California And The Pacific Northwest Tuesday Morning...
A Strong Cold Front Plunging Southeastward Out Of The Northwestern U.S. Will Be The Main Focus Of The Short Range Forecast.

Monday...Eventually Leading To A Swath Of Accumulating Snows
Across North Dakota...Minnesota...And Southeastward Into Northern
Iowa.
Also...Strong Winds Associated With The Front Should Help Squeeze Out Some Moderate Snows Along The Upslope Side Of The Wasatch Range And Colorado Rockies.
By Tuesday...The System Should Be Able To Tap Into Some Gulf Moisture As It Begins To Progress Eastward Towards The Appalachians...Leading To Some Heavier Precipitation Both Ahead Of The Cold Front Crossing The Lower Mississippi/Tennessee Valleys As Well As Near The Anchoring Surface Low Tracking Northeastward Towards The Ohio Valley.
Elsewhere Across The Nation...An Upper Vortex Slowly Spinning Near
The New England Coast Will Keep Light Snow Showers In The Forecast Across Much Of The Northeast And Down Into The Lower Great Lakes Region.
