chietanen Posted November 18, 2014 Share Posted November 18, 2014 The asymmetry of this band is very cool. The northern edge is intense with a very sharp cut-off...the southern edge just gradually diffuses out. The airport would have had a shot at the 24 hr record had this been another 5-10 miles north. That's what I was thinking. Seems like this event will easily exceed 38"/24 hours in the immediate Southtowns based on spotter reports. Any idea what gives it that intense northern edge?

Coastal over on the New england forums was inquiring about this same thought. Any idea why the strongest is on the northern edge of a band off of Erie, yet in the middle of the band off the Tug.

OSUmetstud Posted November 18, 2014 Share Posted November 18, 2014 0.25" 1 hr water equivalent is showing up near Elma/OP/Lackawanna. That's probably 5"/hr. Who would have thought a November 18th heavy LES event was actually too cold to generate major thunder and lightning? The -10C isotherm is too close to the ground and there probably isn't a ton of graupel in the cloud. Link to comment Share on other sites More sharing options...
crownweather Posted November 18, 2014 Share Posted November 18, 2014 I think I found my new sig. Look at this picture! OMG Just commented to my wife, "Hey, we just drove that last month and saw a hockey game at the First Niagara Center". lol. The pictures have been stunning!! Thought yesterday's NWS BTV 4 km WRF was overdone in it's forecast of 5 feet of snow in the southtowns. Now, I think it was onto something. Also, I didn't think that the northern cutoff line would be so sharp. (yep, I'm just starting to learn how to forecast LES - what a challenge, but I'm love it!!)

OSUmetstud Posted November 18, 2014 Share Posted November 18, 2014 As for the sharpness, I wonder if it has something to do with the Boston Hills causing further ageostrophic convergent flow toward Buffalo. Link to comment Share on other sites More sharing options...

OSUmetstud Posted November 18, 2014 Share Posted November 18, 2014 850's are more aligned with the surface over Lake Ontario, not as much over Erie? idk. When I was at SUNY Oswego, we saw the same thing happen when the Ontario band sank south toward the shoreline on a 280 flow. The southern edge would be sharp and intense, and the opposite for the northern part of the band. The additional frictional convergence seemed to aid that.

heavy_wx Posted November 18, 2014 Share Posted November 18, 2014 As for the sharpness, I wonder if it has something to do with the Boston Hills causing further ageostrophic convergent flow toward Buffalo. I've seen that asymmetric structure off of Lake Ontario as well. There was a case back in December 2010 we observed with the DOW radar where the northern edge had a much sharper gradient in reflectivity than the southern edge. Here's a recent scan from KBUF. You can see the highest reflectivity and low ZDR near the northern edge collocated with the convergence zone implied by the radial velocity (pink next to blue colors). My guess is that there is a land breeze from the northern shore of the lake that has a rather horizontally-uniform structure. At the southern shore of the lake, winds increase in speed going from the land to the lake due to friction, leading to low-level divergence. This offsets the general low-level convergence due to the diabatic heating from the less organized part of the band. On the northern edge of the band, the greatest low-level convergence occurs where both the well-organized land breeze and diabatic heating effects contribute.

josh_4184 Posted November 18, 2014 Share Posted November 18, 2014 Nice Pics, I am in awe, never experienced anything like that, it makes my two feet look like two inches lol. Why can't Lake Michigan be about 500 miles longer. I bet some areas will see 6 feet total, plus Thursday looks like another outbreak wnw up this way again not sure about Western NY though.

It's legit insane! There is another lake effect snow watch for Thurs... ...LAKE EFFECT SNOW WARNING REMAINS IN EFFECT UNTIL 1 PM ESTWEDNESDAY......LAKE EFFECT SNOW WATCH REMAINS IN EFFECT FROM LATE WEDNESDAYNIGHT THROUGH LATE THURSDAY NIGHT...* LOCATIONS...ERIE...GENESEE...AND WYOMING COUNTIES INCLUDING THE BUFFALO METRO AREA. NORTHERN EXTENT OF THE SNOW BAND FROM ROUGHLY A LINE FROM DOWNTOWN BUFFALO TO DEPEW AND BATAVIA.* TIMING...WARNING THROUGH MIDDAY WEDNESDAY. WATCH FROM LATE WEDNESDAY NIGHT THROUGH LATE THURSDAY NIGHT.* ACCUMULATIONS...SNOWFALL RATES OF 3 TO 5 INCHES PER HOUR IN THE MOST INTENSE PORTION OF THE BAND. THIS WILL BRING STORM TOTALS TO 5 TO 6 FEET IN THE MOST PERSISTENT SNOWS.* WINDS...SOUTHWEST 20 TO 30 MPH WITH GUSTS TO 40 MPH PRODUCING LOCALIZED BLIZZARD CONDITIONS AT TIMES WITH SIGNIFICANT BLOWING AND DRIFTING SNOW. This might be my all time favorite Lake effect storm. Link to comment Share on other sites More sharing options...
chietanen Posted November 18, 2014 Share Posted November 18, 2014 I just zoomed in on the radar and that intense northern part of the band is literally sitting on top of Cazenovia Park which is 3 houses down from where I grew up. Waiting for some pics from my family. The pics you guys are posting are incredible. Thanks for sharing! Link to comment Share on other sites More sharing options...
