....Southeastern Massachusetts... Day 1...

The powerful winter storm exiting the Carolinas this morning will 
graze southeastern New England today with generally light snow but 
very gusty winds. WPC probabilities for at least 4 inches of snow 
are 10-30% over Nantucket and into parts of Cape Cod (e.g., Chatham).

....Northern Plains through the Upper Midwest and Great Lakes... Days 1-3...

A surface front will move out of the Upper Midwest into the 
western Great Lakes today then into Michigan and the eastern Great 
Lakes Monday. Snow will be light, generally 1-3", as the system 
remains progressive. Another round of light snow arrives in the 
northern High Plains on Monday and ending Monday night, but totals 
are likely to be below 3 inches. Some areas in the U.P. may see 
several inches of the three-day period with modest lake effect snow
behind the front. 

....Ohio Valley & Central Appalachians... Day 3...

The shortwave trough responsible for light snow in the northern 
High Plains on Monday will dive into the Middle MS Valley early 
Tuesday morning and race into the OH Valley by Tuesday afternoon 
and the Mid-Atlantic by Wednesday morning. Weak 850-700mb WAA and 
mid-level moisture will favor light snowfall in a west-to-east 
areas. Most snowfall amounts will be generally a coating-2", but 
some upslope enhancement into the central Appalachians may allow 
for a bit more. Here, WPC probabilities for at least 4 inches of 
snow are low (10-20%). Light snow will extend eastward into the 
Mid-Atlantic early Wednesday.
