...WINTER STORM WATCH REMAINS IN EFFECT FROM FRIDAY MORNING THROUGH MONDAY MORNING... * WHAT...A rapid switch from rain to snow with sharply falling temperatures into the teens and single digits will result in a flash freeze on Friday. From Friday afternoon through most of the weekend, very strong winds, heavy lake effect snow and significant blowing and drifting snow will be possible. Winds could gust as high as 65 mph Friday into Friday night. Localized blizzard conditions are possible. * WHERE...Niagara, Orleans, Erie, Genesee, Wyoming, Chautauqua, and Cattaraugus counties. * WHEN...From Friday morning through Monday morning. * IMPACTS...Travel for the holiday weekend, including Friday, could be very difficult to impossible at times. Areas of blowing snow could significantly reduce visibility with whiteouts and localized blizzard conditions possible. The most persistent and worst conditions will be where lake effect snow is most widespread, which is still uncertain at this time. Winds this strong could cause tree damage and power outages. Cold wind chills as low as 10 to 20 below zero this weekend could cause frostbite on exposed skin in as little as 30 minutes.

Buf NWS calling this a once in a generation type event. Feet of snow, 70+ mph wind gusts, with whiteout conditions.

I'm in the Northeast and have over 100" already.

Always love reading your winter outlooks. Most detailed one out there.

Have never seen anything like what Buf NWS has in their forecast discussion

Never seen anything like it. I might be at 150" before the new year lol.

I've been reading Buffalo Forecast discussions for over 20 years and have never seen one like the one issued this morning. Paralyzing lake effect, climatologically off the charts, bombogenesis, once in generation type event.

Come chase this one

Talk about some crazy noon runs. 150" before the new year?

HWO from Buf. A significant winter storm appears likely to develop and track northeastward across the eastern third of the country Thursday and Friday. Chances are increasing that this system will bring a warmup and widespread rain Thursday and Thursday night...followed by sharply colder conditions and a flash freeze on Friday along with a changeover back to snow. Strong winds will also be possible Friday night and Saturday...with potentially significant lake effect snow also likely developing Saturday and continuing through Christmas Day. Potentially significant lake effect snow and strong winds is expected Friday night and Saturday. The strong winds could also bring lakeshore flooding concerns to areas along the Lake Erie shoreline.

Obviously we just had a big event and not one post here. Everyone is on the discord now, if anyone wants an invite to it PM me on here.

Few vids from the storm Another from the Adirondack storm

Picked up 21.3" with the last LES event, brings me over 100" on the year already. Looks to be another one coming next weekend with the potential for very high winds accompanying the bands.

This ones gonna be massive, has historic potential. Good luck to you guys out west!

I'll be there for it if it happens!

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... ...Significant lake effect snow becoming more likely this weekend off both Lake Erie and Lake Ontario... Confidence is continuing to grow that there will be a round of significant lake effect snow off both Lake Erie and Lake Ontario this weekend. The more impactful snowfall will likely be focused from the Buffalo southtowns into the western Southern Tier and across the Tug Hill region. Still a little bit earlier, but the current thinking would place the city of Buffalo and the city of Watertown OUT of the axis of the more SIGNIFICANT snowfall. Deepening low pressure across eastern New England by Friday night will move up the New England coastline during the weekend. This will draw gradually colder air into the region Friday night in the wake of the occluded frontal boundary. The incoming air aloft should grow cold enough to support a lake response starting later Friday night with a band of lake effect snow expected to begin east/northeast of Lake Erie. Widespread synoptic snows associated with the coastal low will continue across north central New York. The synoptic snows across north central New York will gradually wind down Saturday, leaving the focus for the remainder of the weekend on the potential for heavy lake effect snow. The airmass coming across the lakes will continue to grow colder with time as 850 mb temperatures eventually drop down to -10C to -12C range as deep synoptic moisture remains in place. This should easily support heavy lake effect off both Lake Erie and Lake Ontario. At this forecast range, there does seem to be a general overall model support for an initial southwest flow bringing the potential for the heaviest lake snows to organized to the northeast of the lakes, including the Buffalo metro area and Watertown. However, this is most likely occur for a relatively short duration, generally in the Saturday into Saturday evening time frame. The coldest air would have yet to arrive by this time, so the intensity of the lake effect snow bands are a bit uncertain. Nonetheless, this would be the most favorable time frame for the Buffalo metro area and Watertown to receive the heaviest snowfall. Trough moving through the region Saturday night will bring the coldest air in its wake, but also veer steering winds more westerly (about 260 degrees) and send the heaviest lake snows southward and place the orientation of the heaviest lake snow off Lake Erie south of Buffalo into the Southern Tier and eventually more on the Tug Hill instead of Watertown/Fort Drum. This flow regime will likely stay in place for a more sustained period of time likely through the day on Sunday and even into Sunday night. The lake band intensity should pick up during this time with the potential for snowfall rates of greater than 2 inches per hour at times, leading to significant snowfall totals.

Lake Erie is at 43 degrees, 3 degrees above average for the date.
