SATELLITE ANALYSIS AND TRENDS...WITH SFC LOW SEEN SPINNING IN VIS IMAGERY
OVER CANADA JUST N OF THE ERN PART OF LK ONTARIO..WINDS ARE WELL ALIGNED
TO PRODUCE SOME GOOD LK EFFECT SNOWS ACROSS ONTARIO AND ERIE. STLT WINDS
SHOW MID LVL FLOW OF 25-30KTS FROM THE W ACROSS ONTARIO AT THIS TIME AND
30-40KTS OF WNW FLOW ACROSS ERIE. WITH WINDS ACROSS ERIE ALIGNED ON THE
MINOR AXIS OF THE LK..EXPECT LGT TO MOD SNOWS IN MULTIPLE BANDS INTO NE
OH/NW PA/WRN NY. SOME OF THE MULTIBAND SNOWS OFF HURON LOOK AS THOUGH
THEY WILL CONTINUE TO FLOW ACROSS NERN LK ERIE FOR THE NEXT 3-6 HRS.HAVE
NOTICED IN VIS IMAGERY RECENTLY A BAND THAT IS ACROSS LK HURON THAT HAS
SINGLED ITSELF OUT FROM THE REST AND IS TRYING TO EXTEND ACROSS THE NERN
END OF LK ERIE. THIS BAND ACTUALLY STARTS OVER EXTREME ERN LK SUPERIOR
BEFORE CROSSING PARTS OF MI TO PICK UP ADDITIONAL MOISTURE ACROSS LK
HURON. THE END OF THIS BAND HAS BEEN MOVING NEWD TWDS THE WRN END OF LK
ONTARIO OVER THE LAST 1-2 HRS AND THINK THAT IT MAY FOLLOW THE FLOW AND
EXTEND ACROSS AT LEAST SOME OF LK ONTARIO AS WELL. ASSUMING THE SINGLE
BAND DOES THIS..SNOWFALL RATES WOULD INCREASE GREATLY WITHIN THE BAND
AND WHEREVER THE BAND IS OVER AS IT WOULD GAIN YET ANOTHER MOISTURE
SOURCE. BELIEVE SNOWFALL RATES OF 1-2"/HR WOULD BE POSSIBLE WITHIN THIS
BAND AND IT LOOKS LIKE IT WILL AT LEAST KEEP THE CONNECTION OFF OF HURON
IF IT LOSES THE SUPERIOR CONNECTION.  WILL CONTINUE TO MONITOR. SEE WEB
ADDRESS IN ABOUT 10 MIN FOR GRAPHIC.
