   ...New England...   
   Day 1...   
      
   The final bands of the major winter storm shift east from New   
   England this evening. A couple additional inches are possible after   
   00Z over much of Maine down through the Mass coast.   
      
      
   ...Great Lakes...   
   Days 1-3...   
      
   Broad cyclonic flow and trough passages persist across the Great   
   Lakes as low pressure over Hudson Bay shifts south over Ontario   
   through Thursday. These will produce rounds of lake effect snow=20   
   (LES) particularly starting Tuesday behind a notable upper trough   
   passage. According to GLERL, Lake Erie is essentially ice=20   
   covered, so available moisture will be limited there while Lakes=20   
   Superior and Ontario remain largely. Westerly flow allows Day 2/3=20   
   PWPF for >6" are over 50% in the Tug Hill and just Day 2 for the   
   eastern U.P. of Michigan.   
      
      
   ...Cascades...   
   Days 2/3...   
      
   The next trough axis shunts the powerful ridge east Tuesday night   
   with precip over the WA Cascades then through Thursday. Snow levels   
   rise from 4000 to 5000ft over the WA Cascades Wednesday through   
   Thursday. PWPF for >6" is 40-70% above the snow level (above pass   
   level) by Thursday.   
      
      
   The probability for significant icing is less than 10 percent.
