EVENT...ERIE LK EFFECT SNOW IN TRANSITION FROM MULTI-BAND TO SINGLE
BAND EVENT
.
SATELLITE ANALYSIS AND TRENDS...VERY NOTICEABLE CHANGE IN DIRECTION ON
VIS IMAGERY BY LK EFFECT BANDS ACROSS LK ERIE WITH PASSAGE OF UPPER LVL
TROF AXIS. MUTLI-BAND EVENT SHOULD NOW TRANSITION TO MORE OF A SINGLE
BAND AS THE SFC/LOW LVL FLOW ACROSS THE LK IS FROM THE SW OVER ERIE'S
MAJOR AXIS. SMALL WAVE IS SEEN WITHIN THE SNOW BANDS MOVING NEWD ACROSS
ERIE FROM THE FAST CHANGE IN DIRECTION WHICH COULD PROVIDE A QUICK BURST
OF HEAVIER SNOW AS IT COMES ASHORE. 22Z OBS SHOW THE HVY SNOW AND 0.3
MILE VISIBILITY AT ERIE PA THAT HAS RESULTED FROM THIS SMALL WAVE. IT
SHOULD CONTINUE INLAND TO PUSH NEWD TO BRING MORE INTENSE SNOWS TO
KDKK AND KJHW WITHIN THE NEXT HR..LOOKS AS THOUGH IT WILL STAY JUST S
OF KBUF THOUGH. IR TEMPS HAVE COOLED INVOF THIS SMALL WAVE TO -29C AND
IT IS LIKELY THAT IT IS PRODUCING 1-2"/HR SNOWFALL RATES.
.
EXPECT HEAVIEST SNOW CONTINUING THROUGH THE EVENING TO BE COME ASHORE
BETWEEN KERI TO JUST N OF KDKK AND MOVING INLAND. SHOULD SEE COOLING
CLOUD TOPS BESIDES THOSE ASSCD WITH THE SMALL WAVE THAT IS PROPAGATING
ALONG THE LE BANDS CURRENTLY..DUE TO AN INCREASED FETCH OVER THE LK AND
MERGERS INTO A MORE COHERENT LE PLUME. WILL CONTINUE TO MONITOR.
