SATELLITE ANALYSIS AND TRENDS...BIG PICTURE FROM GOES WATER VAPOR LOOP
SHOWED BROAD LOW PRESSURES ALOFT ACROSS ONTARIO AND QUEBEC CANADA WITH
AN EQUALLY BROAD POSITIVE TILTING TROUGH EXTENDING LK ERIE TO
WESTERN TN.   ANOTHER BELT OF FASTER WINDS ON WEST SIDE OF TROUGH FROM
THE DAKOTAS TO MO/IL WAS HELPING TO DARKEN THE AREA FROM SE MO INTO
WESTERN KY.  BUT TROUGH PROGRESSIVE SO UPPER LEVEL WINDS EASTERN LAKES
WILL GRADUALLY SHIFT FROM SW TO WEST.  SURFACE WINDS ALREADY WSW TO WEST
ACROSS LK ERIE AND MULTI PLUME EVENT IN PLACE AND AFFECTING SHORELINE FROM
E CUYAHOGA COUNTY OH THRU ERIE COUNTY PA TO S ERIE COUNTY NY AND FANNING
OUT INLAND FROM THERE.  AS COLD AIR CONTINUES TO STREAM IN AND SURFACE
FLOW GETS BETTER ALIGNED WITH UPPER LEVELS...EXPECT BETTER ORGANIZATION
AND HIGHER SNOW RATES OFF ERIE IN AREAS OUTLINED ABOVE...BUT UNTIL LATER
THIS EVENING OR DURING THE OVERNIGHT.  OFF LK ONTARIO...SAME KIND OF DEAL
WITH UPPER LEVEL SWLY AND LOWER LEVELS MORE WESTERLY AND WITH BETTER
SHAPE OF LAKE ONE OR TWO PLUMES IDENTIFIED ACROSS THREE QUARTERS OF
LAKE ONTARIO...THUS MORE INTENSE AND FOCUSED HVY SNOW FAR N OSWEGO AND
S THIRD TO S HALF OF JEFFERSON INTO N HALF OF LEWIS COUNTY WHERE RATES
GENERALLY ONE QUARTER TO THREE QUARTERS OF AN INCH PER HR...WITH NEAR ONE
INCH PER HR IN MOST FOCUSED AREA OF S JEFFERSON INTO NW LEWIS COUNTY.
AS GOOD AS THIS SOUNDS...VERTICAL VELOCITIES NOT VERY HIGH ON LATEST
MODEL OUTPUT...SO AS RESULT MODERATE SNOW RATES.     WILL CONTINUE TO
MONITOR...SEE GRAPHICAL REPRESENTATION AT INTERNET ADDRESS BELOW...
