so many forecasts had me in the sweet spot down here in madison county, 18+ or

so.  the band was here for a short while this am, but has since settled in north of us,

 

just came across this webcam in sylvan beach..  looks like it's hammer time there!

i don't know how to capture some of the video, but right now it's S++

 

Wow, that is definitely heavy snow! Visibility only a few hundred yards if that.

The band coming into Niagra Falls NY is directly off of Lake Huron (see Exeter ON radar).

...LAKE EFFECT SNOW ADVISORY REMAINS IN EFFECT UNTIL 7 PM ESTTUESDAY...* LOCATIONS...NIAGARA AND ORLEANS COUNTIES.* TIMING...THROUGH EARLY TUESDAY EVENING.* ADDITIONAL ACCUMULATIONS...1 TO 3 INCHES THIS AFTERNOON...2 TO  4 INCHES TONIGHT...UP TO 2 INCHES TUESDAY...AND AN INCH OR LESS  TUESDAY EVENING.* WINDS...WEST 15 TO 25 MPH WITH GUSTS UP TO 40 MPH PRODUCING  SIGNIFICANT BLOWING AND DRIFTING SNOW.* VISIBILITIES...AS LOW AS A QUARTER MILE AT TIMES.* IMPACTS...LAKE EFFECT SNOW AND BLOWING SNOW WILL CREATE  HAZARDOUS DRIVING CONDITIONS AT TIMES WITH SNOW COVERED ROADS  AND LOW VISIBILITIES.

Band off the SE of Ontario should shift decidedly south in the next hour....SYR may be the target for a bit this evening....

George...as soon as u posted that I left.phoenix where it became briefly p/c as the band may have wavered north a few miles...it's back though here in Clay...just measured...7.5" since noon.

10" of snow so far in Phoenix. Band is weakening pretty fast but looks to be widening. Dave Eichorn said a clean sweep through the city and then reforming to a lesser degree. More than not, the bands never get their act together again like before. That was probably the best of this event but was a good one.

Monroe can never lock in with these WNW events. It's a lost cause, same as it ever was.

Man i feel for ya, it's turning out to be a dud for ROC metro area. only 1-3" expected for the city with 4-6" falling along the lakeshore and eastern burbs per latest AFD.

POTENTIALLY A BETTER SHOT FOR LAKE EFFECT SNOWS INCREASES AGAIN FOR

A TIME LATER WEDNESDAY INTO EARLY THURSDAY...AS 850 MB TEMPERATURES

FALL TO AROUND -16C IN THE BASE OF A DEVELOPING 500 MB TROUGH AND

INVERSION HEIGHTS RISE TO AROUND 7K FEET. THE LOW LEVEL FLOW WILL

BACK ENOUGH FOR SOME LAKE SNOW TO DRIFT TOWARD THE BUFFALO AND

WATERTOWN AREAS FOR A TIME LATE WEDNESDAY AND WEDNESDAY AND

WEDNESDAY NIGHT...BUT SHEAR PROFILES SUGGEST ANY ACCUMULATIONS WILL BE

LIMITED.

I may be near 10", I finished driveway at 3:30 and just went to the store (big mistake), had to be another 2-3" down in less than an hr.

We did receive 3" between about 3:30-4:30 pm, was impressive. Total of 10.5" IMBY. Looks like we will be on range of band for a while. I'm hopeful an upstream wind shift (s/w?) over Lake Huron may push it back North a tad later tonight. It's falling off the lake SE end now, which is never great for productive snow, except maybe out towards ROC.

Snow rate has picked up here (but still not nearly as intense as it was earlier) as that band expands over Monroe county. Measured a whopping total of 3" on the ground (most for the season so far) at 3 pm, about 1" fell during the passage of the earlier band.

 

At least it looks like winter again...been a long time.

If Monroe County (Rochester) can never seem to lock in to the LES in the WNW events, and that is a fairly important wind direction, then how is it that Rochester averages 99" per winter and Buffalo averages 94.8" per winter? Because obviously Buffalo airport has gotten into some super-bands over the years that bump up snow averages over a 30 yr period.

Just guessing, but the 3 or 4 Nor' Easters that either hit us or graze us in CNY during an average season, puts ROC into a northerly flow off Ontario, to enhance the synoptic system, that just due to ROC more eastern location, on average, gives them more snow than BUF during those events.

Eichorn was a great mentor. He doesn't have a PhD but he really knows a lot of the nuances of LES and is a very good forecaster. Hope his forecast for this event has been good... Looks like the band pretty much fell apart already

We will transition to a period of multi-bands for awhile tonight (Main band actually acts as a mini cold front or wind shift line)....then, winds will help to reconnect upper lakes and try and make the multi bands become singular again around midnight.

Rochester nickles and dimes its way to 100" a year based on Ontario never freezing so it gets good enhancement in the comma head of deformation bands when synoptic systems hit. KBUF is actually averaging 100.4" since the year 2000 (15 year period) which may be over that of KROC. And as far as Syracuse averaging so much, it's because its well north of the city. Syracuse proper probably gets 20-30" less a year than the airport due to the favorable location for WNW LES events.

Idk if this is what Delta meant, but to me it seems we have trouble getting a band to setup and just produce for 12-18-24hrs at a time. Sure, it may snow at a decent clip for a time, but bands just seem to always be on the move.

For MBY, this seems more of an issue with N/NW wind Ontario les bands than it does SW winds from Erie..
