Any chance the LO band sinks to southern tug? Or just give up? The NWS map looks good, but I don’t see any support in models. Thanks! 

We will probably see branches wisp off of the main band and sweep through...other than that, I give up. The pattern this whole winter has blown chunks for our localized area.

Yeah, all the upstream connections are now shifting north. NWS also mentions this. The band never drops as far south as we hoped

The AFD at 2:29 states into the Northtowns for about 4 hours this evening with a sharp cutoff at the Erie/Niagara border where a trace can be found, while the heart of the band will produce up to 8"...on top of this they are also keying on tomorrow night in the metro for about a 6 to 9 hour window of LES as well!!!

Jeez. 1-2' more of snow today and tomorrow.

Upstream satellite and observations are showing a wind shift across
western Lake Erie in response to the next frontal boundary. This
wind shift will cause the winds to back across the Lake and begin to
shift the Lake Erie bands to the north. A shortwave trough will move
into the Upper Great Lakes by this evening and this will increase
lift and moisture across the eastern Great Lakes. The Lake Erie band
will become better organized by early evening while it moves
northward into Metro Buffalo and across the Northtowns. Snowfall
rates of 2-3 inches/hr are expected. Consequently the lake band
will move out of the Southern Tier and Southtowns with snow
persisting right along the Lake Erie shoreline. Additional snow
accumulation of 5-10 inches are expected in the Winter Storm
Warning area from northern Chautauqua, NW Cattaraugus, Erie and
western Genesee and western Wyoming Counties. A tight gradient
of snow accumulations will be located near the Niagara/Erie and
Orleans/Genesee borders. A cold front will move across Lake Erie
and into western NY by Saturday morning. This will shift the
lake band back to the south giving the Lake Erie shoreline to
the Southtowns another round of snow. An additional 3 to 6
inches expected overnight for these locations.

Southwest winds will become west, east of Lake Ontario this
afternoon. With 850mb temperatures to -18C and lake induced
instability has produced a well-organized lake band across
Jefferson and northern Lewis counties. Favorable conditions will
continue into this evening with snow rates ramping up as winds
become westerly. Snow rates 2-3 in/hr are expected across the
Tug Hill by evening. Winds will back to the southwest this
evening resulting in the lake band to move north again. Heavy
lake effect snow will continue across the northern Tug Hill
region with additional snow accumulations of 1-1.5 feet across
the Tug Hill to about a foot across Jefferson and northern Lewis
counties tonight and into Saturday morning. It is likely that
only the extreme northern section of Oswego county will be
impacted with the rest of the county seeing little.

Cold temperatures expected tonight with temperatures falling
into the single digits to the low teens by the lake shores. Lake
bands weaken into Saturday morning as dry air moves into the
region and equilibrium levels come crashing down. Additional
snow amounts of 1-2 inches are expected from the Lake Erie
shoreline to the Southtowns and 2-4 inches across the northern
Tug Hill region. Warm air advection increases aloft by afternoon
and temperatures will rise into the upper teens to low 20`s.

For some incredibly odd reasons channel 4 in Buffalo (WIVB) is staunch that the LES gets no further than the southtowns tonight...even though it's already snowing here...they blew the forecast last night and they're well on their way again!!!


Can’t be any worse than Channel 2. They actually painted a big fat zero right over the whole metro for the remainder of the day...

..A BAND OF LAKE EFFECT SNOW WILL AFFECT NORTHERN WYOMING...ERIE...
NORTHWESTERN LIVINGSTON AND GENESEE COUNTIES...

At 346 PM EST, a band of lake effect snow producing snowfall rates
of 1 to 2 inches per hour is moving north toward the Metro Buffalo
region.  This band will strengthen and have an adverse effect on the
commute for anyone travelling south or east of Buffalo through this
evening. The band will move north into Metro Buffalo by around
nightfall, then weaken and move back south overnight.

During the evening hours, expect snowfall rates of 1 to 3 inches per
hour within the 15 mile wide band. Winds in excess of 30 mph will
produce significant blowing and drifting snow with brief periods of
near whiteout conditions.  Expect from a trace of snow from
Tonawanda to as much as additional 8 inches, possibly more, tonight
under the center of the band.
