The Euro definitely sucks for the metro area and the southtowns. Cold air arrives late and on westerly winds. Looks good for those in Chautauqua, Cattaraugus, and southern Erie Counties.

Isn't the Euro better at predicting Synoptic systems then Mesoscale events like LES? Aren't models such as the BufKit, NAM, SREF far better for this?

even the northtowns get in action on the sref lol

Those images you posted are once the winds shift NW Ayuud. We need southwest winds to really hit the metro hard...Northwest winds create small tiny bands of snow and is so dependent on your location. NWS seems convinced of band starting out at Metro points northeast dropping south across southtowns and into ski country on Monday.4-8 for Metro and 8-16 for southern Erie county and ski country. Will see if it pans out....

i've never used the sref for lake-effect so I'm not sure about that. BUFKIT is just a model tool. It's only as good as the NAM file or the GFS file that are used in it. The Euro is tough to beat at this range. And there is a synoptic element to this anyway...the euro has the low weaker and brings the cold air in significantly later...why would the NAM be better at diagnosing that?

can you post a link for what sref product you are looking at specifically?

Sunday night through Monday.

2" or less at the airport

3" or less in the populated southtowns

3-6" in the higher elevations of central Erie

6-12" in the higher elevation of south and southeast Erie

1-2 ft in northern Cattaraugus and the Chautauqua Ridge

Airport could get "saved" on Monday night when the arctic front comes through and winds flip NW/NNW

From Don Paul:

Again, Buffalo and the Ntowns are NOT out of the significant accumulation picture, despite what some bloggers speculate–and that’s why they’re in the Watch. The heaviest amounts will end up in Ski Country, but this isn’t an all-or-nothing-at-all proposition. There continues to be a significant chance for several hours of accumulating LES in the meto area and NE ‘burbs tom’w evening, with frequent whiteouts, before the veering takes place.

You can't go by the 39 degree water temperature to determine lake instability. Because that is not the temperature of the majority of the lake. If you look at the link below you will see 85% of the lake is at 40 degrees and 25-35% is at 42-45 degrees. This will create enough instability sunday night to create LES on a SW/WSW flow. The strong winds is what worries me the most....

Its not a model, its in Nowcast mode. And it is accurate. The lake temperature is 39 degrees... At 30 feet in the Buffalo Harbor...Not the entire lake, it varies all over, and can be changed in days with windy conditions and upwelling.

OUR TURN FOR LAKE EFFECT WILL COME LATE MONDAY AND MONDAY NIGHT

WITH THE SECONDARY FRONT. THIS SHIFTS THE LOW LEVEL WINDS TO NW BY

TUESDAY. 850MB TEMPS FALL INTO THE LOW -20S C WHICH IS THE COLDEST

SO FAR THIS SEASON. MONDAY NIGHT THE FLOW WILL BE TRANSITIONING SO

NO SINGLE BAND WILL SET UP OVER A LOCATION FOR VERY LONG. ON

TUESDAY THE FLOW IS 330 SO MULTIBANDS ACROSS CENTRAL NY INTO THE

NORTHERN TIER OF PA. WIDESPREAD SNOW BUT NO ONE LOCATION WILL HAVE

THAT MUCH FOR ANY 12 HOUR PERIOD. UPPER LEVEL TROF MOVES EAST

TUESDAY SO WAA STARTS LATE TUESDAY.

MOST LIKELY EVENT WOULD BE A LAKE EFFECT SNOW ADVISORY FOR ABOUT

HALF OF OUR CENTRAL NY COUNTIES MONDAY NIGHT TO TUESDAY NIGHT.

OTHER WEATHER MARGINAL FOR ANY FLAGS. WIND CHILL TEMPS FALL

BELOW ZERO LATE MONDAY NIGHT AND STAY THERE INTO WED. AIR TEMPS

ONLY BETWEEN 10 AND 20 WITH A 15 TO 25 MPH WIND. EASILY THE

COLDEST DAY OF THE WINTER TO DATE.

I respect Don Paul but I don't agree with this.

A question for you locals and mets - a few friends are leaving for Holiday Valley tomorrow to go skiing for a few days. They are coming over tonight for a party. Any suggested timeline for them to be at their destination before the 'snow show' begins? I am thinking if they are there by 6 pm they should be OK, or is this wrong? If they ask snow totals - 1-2 feet about right?

6pm would be fine imo. Yeah, 1-2 ft Monday morning through Tuesday morning. It's possible the top of the hill at 2250 ft could exceed 2 ft...but I'd think the best chance of that is on the chautauqua ridge since they get slammed better on Monday night when the flow turns northwesterly.
