EVENT...ENHANCING LES BAND ACROSS LK ONTARIO
.
SATELLITE ANALYSIS AND TRENDS...LAKE EFFECT SNOW BANDS ACROSS WRN LK
ONTARIO HAVE MERGED TOGETHER INTO A WIDE SINGLE BAND OVER THE CENTER
OF THE LK THOUGH PER LATEST VIS/RADAR IMAGERY IT STILL LOOKS SOMEWHAT
DISORGANIZED AT THIS TIME. S/WV TROF OVER THE MIDATLANTIC LIFTING INTO THE
NE HAS CAUSED A WIND SHIFT OVER THE ERN GREAT LKS THAT IS MORE FAVORABLE
FOR DVLPMT OF A SINGLE PLUME ACROSS THE MAJOR AXIS OF LK ONTARIO. TROF
AXIS IS CURRENTLY CROSSING THE WRN END OF LK ONTARIO PER 22Z WV IMAGERY
AND SHOULD ALLOW FOR WSWRLY FLOW AT LOW/MID LVLS AS OBSERVED UPSTREAM
IN LATEST PLOT OF GOES STLT WINDS. UPSTREAM SFC WINDS IN THE OH VLY AND
INVOF LKS ERIE..MICHIGAN..AND HURON HAVE ALSO TURNED TO BE FROM THE
WSW/SW BEHIND THE TROF AND IN ADVANCE OF THE NEXT S/WV. FOR THE NEXT
FEW HRS THOUGH..STILL EXPECT A MOSTLY W WIND ACROSS THE LK ALLOWING THE
CURRENT SNOW BAND TO SINK INTO NRN OSWEGO COUNTY NEAR PULASKI. DUE TO
THE CURRENT DISORGANIZED LOOK OF THE BAND..ESTIMATE THAT SNOWFALL RATES
ARE PROBABLY AROUND OR UNDER 1"/HR..THOUGH WHEN THE BAND PASSED THROUGH
KART EARLIER..VISIBILITY FELL TO 0.3 MILE AND S+ WAS REPORTED. IF THE
SNOW BAND CONSOLIDATES MORE AS IT SHOULD OVER THE NEXT 1-2 HRS BECOMING
W-E ORIENTED..EXPECT AN INCREASE IN SNOWFALL RATES. SEE WEB ADDRESS FOR
GRAPHIC IN ABOUT 10 MIN.
