Mesoscale Discussion 1794
   NWS Storm Prediction Center Norman OK
   0755 PM CST Sun Dec 10 2017

   Areas affected...lee of Lake Erie and Lake Ontario

   Concerning...Heavy snow 

   Valid 110155Z - 110700Z

   SUMMARY...Persistent lake effect snow bands extending west-northwest
   from Lake Erie and Lake Ontario will persist into the overnight.
   Highest snowfall rates from these bands are peaking now (locally in
   excess of 2 inches per hour) and should begin to weaken later
   tonight.

   DISCUSSION...Lake effect snow bands have persisted through the
   afternoon across portions of Erie, Wyoming, Genesee, and Orleans
   Counties in western New York and Jefferson, Oswego, Lewis, and
   Herkimer Counties across northern New York. Observations suggest
   that these bands have intensified over the last few hours and are
   producing snowfall rates in excess of 2" per hour, with locally
   higher rates likely. Given water temperatures in the mid 30s F, 850
   millibar temperatures of -9.5 C (per 00Z BUF sounding), and westerly
   low-level flow around 35 knots, these lake effect snow bands will
   continue for the next 4-6 hours. In the 06-08Z time frame, a surface
   cold front should move through the area resulting in low-level flow
   veering. As such, lake effect snow bands will shift south and west,
   with an overall weakening trend given the shorter fetch over the
   lake.

After watching Andrew Baglini on WIVB I'm even more certain monday night through Wednesday will produce 8 to 12 inches from Niagara Frontier to Orleans County where heading east amounts will increase. The synoptic moisture after the low goes by Tuesday will be enhanced and blossom over the areas I just mentioned.

8.7" here!  Not crazy but I'll take it!  6.2" in 4 hours from 530-930.  What did everyone else see around BUF today Wonder if anyone in Hamburg OP cracked 2 feet.  

Love nights like this... Cold Quite Desolte...

We had 1” and across the city line in Amherst was 0”. So much for the epic 4-6 inch jackpot from last Thurs-Fri. It’s dismaying to think we could get through this entire gold mine of a pattern with maybe 8” over 10 days.

Still snowing in West Seneca(albeit ighter now). Up to 17.1” since noon on Sunday... 6” in 3 hours fell at one point between around 6-9pm. Orchard Park and Hamburg have to have 3 feet by now.

 

the gradient with this one is astounding reminding me of 2010,2014 (although obviously not as heavy as 2014). Drive 2 miles to my north and there’s 6”, Drive 2 miles to my south and there’s 28”...

"Note the hvy axis north of I90. Oswego looks nice. Also probably early enhancement over Niagara. 

We shall see. I do wonder if some of those 1" amts aren't sleet returns (but it's tot precip-so idk)". 

Why do you Wonder Dave?

Please explain to me how these two soundings from 15Z and 18Z Tuesday show a mix with sleet, and I'm serious?  Do you even know what a Sleet sounding looks like?  That's a serious question too?  Can you interpret the parameters?  This easily answers your questions about sleet very easily! Just off the deck at around H925-H950 which is basically the surface, at or > freezing but it doesn't matter cause it's virtually on the ground!

When I see something that doesn't make much sense to me, and then I do research to back it up, and I turn out to be correct through science, I will speak up!

H850 off the 12K NAM!

I'm trying to figure out how it ip/sleets with H850's between -4-6C!
