EVENT...POSSIBLE LES BAND CONNECTION SETTING UP FROM HURON TO ONTARIO
.
SATELLITE ANALYSIS AND TRENDS...LE BAND OFF OF ONTARIO HAS BEEN PERSISTENT
OVER THE PAST FEW HRS SHOWING NO WEAKENING WITH IR CLOUD TOPS ACTUALY
COOLING/EXPANDING EVEN MORE SINCE PREVIOUS SPENES. CURRENT CLOUD TOP
TEMPS ARE BETWEEN -35C TO -37C SO BAND IS ALREADY LIKELY PRODUCING 2-3"
RATES IN ITS CENTER..POSSIBLY EVEN SLIGHTLY HIGHER. AM CONCERNED THOUGH
BECUASE HI-RES VIS IMAGERY SHOWS A BAND OFF LK HURON STARTING TO EDGE INTO
WRN END OF LK ONTARIO WITH A VERY THIN BAND EXTENDING FROM THE MULTI-PLUME
SNOWS OFF HURON TO THE WRN END OF THE ONTARIO BAND..BEGINNING TO CONNECT.
.
AXIS OF UPPER LVL TROF MOVING ACROSS THE MIDWEST/MIDATLANTIC REGIONS IS
CENTERED OVER LK ONTARIO AT THE MOMENT AND SATL WINDS INDICATE AN ALMOST
DUE WRLY WIND AT LOWER LVLS UP TO 700MB AS WELL AS AT THE SFC. WITH BACK
END OF TROF AFFECTING LK HURON..MORE OF A NWRLY FLOW IS SEEN ACROSS
THE LK AT LOW LVLS THOUGH A WRLY SFC WIND IS REPORTED ACROSS MOST OF
MI. THUS A SINGLE BAND IS SET UP ACROSS THE NRN PART OF LK HURON WITH
MULTI-BANDS ACROSS THE SRN PORTION AND ARE SEEN MERGING INVOF STN CWLS
CONTINUING TO THE NWRN END OF LK ONTARIO INVOF TORONTO.
.
WITH SERN LK ONTARIO TEMPS AS WARM AS THEY ARE..MID 40S TO LOW/MID 50S..LK
INDUCED CAPE PER BUFKIT RUC/NAM FCST SOUNDINGS FOR KSYR AND KART ARE
PRETTY IMPRESSIVE WITH AT LEAST 1400 J/KG FOR BOTH LOCATIONS AT SOME
POINT THIS AFTERNOON. NOTICED THAT KART IN BOTH NAM AND RUC INDICATE
INCREASING CAPE NEARING 00Z..SAME TREND NOTICED FOR KSYR THOUGH NOT AS
MUCH. LE BAND HAS BEEN HOLDING FAIRLY STEADY INTO NRN OSWEGO COUNTY BUT
VIS/RADAR TRENDS SEEM TO INDICATE A SLOW SWD SINKING MOTION. EXPECT WILL
SEE CONTINUATION OF 2-3" SNOW RATES FOR NEXT 3-4 HRS AT LEAST. SEE WEB
ADDRESS IN ABOUT 10 MIN FOR GRAPHIC.
