.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE SHOWED UPPER LOW HAS CLOSED
OFF AND SLOWED TO DRIFTING EAST ACROSS SW QUEBEC NEAR THE SE ONTARIO
BORDER.  NWLY WINDS ALIGNED FAVORABLY FOR LAKE HURON AND GEORGIAN BAY
PLUMES TO MOVE ACROSS LAKE ONTARIO AND E LK ERIE FOR ADDITIONAL MOISTURE
DUMP INTO SW/W NY AND S AND SE LK SHORE COMMUNITIES AND UPLIFT AREAS
AWAY FROM THE LAKE.  THOUGH DISTANCE ACROSS LK ERIE IS SHORT...TRAJECTORY
ACROSS LK HURON AND EVEN SOME ORIGINS BACK TO EASTERN LK SUPERIOR HELPING
KEEP MOISTURE PLUME GOING FOR LIGHT TO MODERATE SNOW WESTERN NY TO JUST
SOUTH OF BUF.  BUT ONCE OUT OF THE LK HURON TRAJECTORY NOT MUCH OCCURRING
IN SW NY INTO NW PA.  BIT DIFFERENT OFF LK ONTARIO AS TRAJECTORY AND PLUME
COMING OFF EITHER FULL LENGTH OF HURON AND/OR GEORGIAN BAY AND THEN OVER
A SIZEABLE LENGTH OF LK ONTARIO...ESPECIALLY THE SE LK SHORE AND INLAND
FOR 1-2 INCH PER SNOWS ESPECIALLY IN OROGRAPHIC LIFT AREA AWAY FROM THE
SE LK SHORE.   UPPER LOW AND FLOW MOVING SLOWLY...SO EXPECT WIND FLOW TO
REACT TO CHANGE SLOWLY AS WELL...SO DON'T SEE MUCH CHANGE IN TRAJECTORY
ACROSS ONTARIO AND ERIE TO CHANGE SNOW BAND ORIENTATION AND INTENSITY
THRU THE EVENING.
WILL CONTINUE TO MONITOR..
