US Final Extended Weather thru Mar 2

Periods Of Snowfall Likely For The Midwest...Great Lakes...And
Northeast...

The 23/00z Guidance Continues To Come Around To The Idea Of A
Sub-1000 Mb Midwest Cyclone Tracking Through Missouri...Illinois
And Northern Indiana On Day 3...Then Transitioning This 'Dying'
Surface Wave On Day 4 Over The Central Great Lakes Into A Series
Of Strengthening Eastward-Propagating Waves (Along/Invof 40n
Latitude) Through Day 7.

The 27/12z Time Frame Seems To Be The Center Point For The Transition To Occur...Generating A Series Of Discernible Wave Impulses Underneath A Strong And Cold Surface High Planted Over Maine/New Brunswick And East Central Quebec.

This Cycle (00z-06z Runs)...Maintained Good Continuity With The
Previous Graphics And 'More Than Enough' Consistency In The Ecmwf Ensemble Means To Anticipate A Closed H5 Circulation Will Very Slowly Track Across The Eastern Great Lakes...Northeast And Into The Gulf Of Maine Between Day 4 And Day 7.

The Duration Of This Particular Upper-Level Storm Track Favors Moderate To Heavy Snowfall Production And Accumulations Across The Mountains Of New England And Coastal Areas Adjacent To The Gulf Of Maine.
