Major LES event-December 24-27


 Share

Recommended Posts

Some of the SR models are dropping the band south much quicker than the NWS says..

 flakes. Expect LES snowbands to remain
across Jefferson/Lewis counties and the northern Tug Saturday
morning, before shifting more to the east of the Lake across
central/southern Jefferson, far northern Oswego and central Lewis
counties Saturday afternoon and evening as winds become more
westerly.

Probably..... Overkill.... But hey can’t measure 48” of snow with a 36” stick!  

haha, thats the spirit!

And if thats a total snow on the ground snowboard; then its honestly in one of the few populated places in this country where you could legitimately hit that number (someday).  If its a 24 hours or less incremental board, then yes, a little bit of overkill.

My Point and click just updated to 1-2 inches tonight.  Wonder what KBuf based that on?   Thats a huge shift and contrary to the 18z runs.  Is it the Christmas miracle that vortmax has been talking about??!!

Are you chasing this weekend? Can always stop by my place for the night if you want. You have to sleep on the couch though. Didn't buy an extra bed yet. :lol:

I'll be playing things by ear.  If there was an incredible band tomorrow I might head out in the afternoon, but not sure how far I would drive to get to it.  Someday when things are more normal I might take you up on that place to crash if things ever got real dicey while I was out there.  If I don't go tomorrow, I might take a drive very early Saturday morning...once again this would be contingent on band placement and intensity.  We shall see.

Off Lake Erie...

Northwest flow early this morning will back to the west by late
morning or midday, allowing multiple bands to develop from northeast
Ohio into the western Southern Tier of NY, with some upslope
enhancement along the Chautauqua Ridge. This will remain the mode of
lake effect through mid to late afternoon. By early this evening
boundary layer flow will be backing to the WSW, which will allow for
a single band to consolidate along the Lake Erie shore of Chautauqua
County into southern Erie County. This band will then move north
towards the Buffalo southtowns and southwest Genesee County by late
evening as boundary layer flow continues to back to the southwest.
Some high-res guidance suggests a brief southward drift back into
southern Erie, western Wyoming, and Chautauqua counties after
midnight before the band moves back north to Buffalo again by
Saturday morning. The band will reach its northern-most point late
morning to early afternoon Saturday into the city of Buffalo and
even the nearby northern suburbs before starting to drift back south
across the southtowns late in the afternoon. Lowering inversion
heights, decreasing moisture, and increasing shear will allow the
band to weaken during the afternoon.

Snowfall rates will occasionally reach 2 inches per hour in this
band of lake effect snow from this evening through midday Saturday.
Total accumulations of 15-20 inches are still likely where the band
persists the longest from western Chautauqua County, the northwest
corner of Cattaraugus County, into southern and central Erie County
including South Buffalo and the densely populated nearby southtowns.
6-12 inches are possible from downtown to the airport and the nearby
northtowns if the band makes it that far north Saturday, with a very
sharp drop off in accumulations heading northward through the
northtowns.
