...HEAVY SNOW DAYS 3 AND 4 FROM THE MIDWEST TO THE INTERIOR
NORTHEAST...

THE MODELS HAVE FINALLY CONVERGED ON THE TRACK OF THE COMPLEX WAVE
CROSSING THE EAST EARLY IN THE PERIOD, WITH ITS MOST MARKED
SENSIBLE WEATHER THREAT BEING A STRIPE OF HEAVY SNOW FROM NORTHERN
ILLINOIS AND INDIANA THROUGH THE INTERIOR NORTHEAST. A CHANGEOVER
FROM RAIN TO SNOW ON THE BACKSIDE OF THE SYSTEM COULD GIVE THE
POPULATED AREAS FROM NEW YORK CITY TO PORTLAND A FEW INCHES OF
SNOW. A SHARP SHOT OF ARCTIC AIR WILL FOLLOW ON THE HEELS OF THE
WAVE, WITH A LONE DAY--THURSDAY, DAY 4--OF WELL-BELOW-NORMAL
TEMPERATURES FOR A GOOD CHUNK OF THE REGIONS AFFECTED BY THE STORM.

AFTER THE EASTERN STORM, RELIED ON THE 00Z/09 ENSEMBLE MEANS AS A
SYNOPTIC GUIDE COAST TO COAST. THESE MEANS SHOW A CONTINUATION OF
A WESTERN RIDGE AND AN EASTERN TROUGH, WITH LESS AMPLITUDE. SUCH A
FLOW REGIME IS TYPICALLY A DRY ONE FOR THE CONTIGUOUS UNITED
STATES, WITH ONLY THE GULF COAST STATES AND WESTERN WASHINGTON
SEEING APPRECIABLE MOISTURE.
