   ...New England...   
   Day 1...   
      
   The major winter storm that swept over the Nation the last few   
   days will continue to gradually exit the Northeast today, with   
   lingering additional snowfall across parts of New England. By the   
   start of the forecast period (12z Mon), the primary surface low   
   will be sliding east into the open Atlantic and only provide for   
   some favorable ocean-enhanced snow from the south coast of ME to   
   eastern MA. Otherwise, mostly light to moderate snow will be   
   associated with a weakening 850mb low tracking across northern New   
   England. Additional snowfall amounts through tonight are expected   
   to range from 3-5", with the highest probabilities (50-80%) for   
   greater than 4" extending from the northern coast of MA to eastern   
   ME. Storm total snowfall amounts from Sunday through the D1 period   
   are expected to exceed 20" across parts of New England.   
      
      
   ...Great Lakes...   
   Days 1-3...   
      
   Broad cyclonic flow will persist across the east, and multiple   
   embedded shortwaves will ride through this trough out of Canada,   
   each one acting to reinforce cold advection (CAA) across the Great   
   Lakes to support rounds of lake effect snow (LES). While GLERL   
   indicates that water temperatures are cooling, Lake Erie is   
   entirely ice covered, and with the very cold temperatures this week   
   continuing, additional ice cover is expected. However, there   
   should still be sufficient instability and moisture to support LES   
   each day through the forecast period. LES is not expected to be   
   extremely intense, although will be efficient downstream of Lake   
   Ontario towards the Tug Hill Plateau at times, and it is this area   
   that is expected to receive the heaviest LES. WPC probabilities for   
   all 3 days indicate a high chance (>80%) for at least 12 inches   
   east of Lake Ontario, with lower probabilities for 8+ inches   
   (30-60% chance) east of Lake Michigan and across the eastern U.P.   
   on the south shore of Lake Superior.
