...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.
