I've not checked western NY--- But looking at the NAM, BGM will be lucky to break 6 in round 2--- warms darn fast. Even up here in Oneonta--- 6 before a mix may be realistic. Fast speed is an issue too--North of SYR to the TUG look to be slammed longer tomorrow. Still--I'll see a foot, maybe 14 inches total. close to 6 here now, 6 before change, 1 inch crap, I inch after??

Hi Keith. Good luck with the new job.

Round 1 up here has been a dud. Only about an inch, but I like your comments quoted above. Any lake enhancement here as this storm is moving more W to E, rather than more S to N?

Yea this storm has huge bust potential..

I think if one takes the city of Oswego and draws a straight line east and west, areas north of that line will stay all snow. Other areas will be pinging in earnest tomorrow and I wouldn't even be surprised if a doozy of an ice storm hits the Southern Tier. I hope that 18z and 0z have better news for us along the I-90 corridor, but that is the way I see it at this point. 4-8" and about 3/4" of sleet is what I see right now. :thumbsdown:

Hey Dave-- We did well. 5.5 inches, maybe 6-- still some snow falling. 6-8 is our best tomorrow. I'm betting you get 12-18--

this is defintely worrisome not sure how this would play out with the occlsion/dryslot......maybe a met can comment for our area

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL704 AM CST TUE FEB 1 2011.UPDATE...

VERIFICATION AT 12Z INDICATES STORM SYSTEM IS RAPIDLY INTENSIFYING AT A RATE AS FAST OR FASTER THAN PROJECTIONS. COMPARING DATA...PLUS USING NUMEROUS TECHNIQUES SUGGESTS THE SYSTEM MAY NOT ONLY BE STRONGER...BUT COULD OCCLUDE OR WRAP UP MORE THAN PLANNED BACK TOWARD OUR AREA. IF THIS OCCURS...THIS COULD RESULT IN EVEN HIGHERSNOW TOTALS...SNOW-FALL RATES AND POSSIBLE THUNDER-SNOW OVER ATLEAST THE SOUTHEAST PORTIONS OF THE AREA. IT ALSO MAY RESULT INSLIGHTLY HIGHER WIND SPEEDS FOR MORE SEVERE BLIZZARD CONDITIONS.THIS RISK SHOULD BE CONFIRMED IN THE NEXT 3 TO 6 HOURS.NO CHANGES ARE PLANNED...BUT INDICATIONS CLEARLY SUPPORT THIS WILLNOT ONLY BE A MAJOR STORM OF NEAR HISTORIC PROPORTIONS...BUT MAYBE A BIT STRONGER FOR AT LEAST OUR SE 1/2 LOCATIONS THAN IS CURRENTLYFORECASTED.INDIVIDUALS SHOULD MONITOR THIS SITUATION FOR POSSIBLE UPDATES ONTHIS POTENTIALLY DANGEROUS SITUATION.

definitely makes the forecast trickier for us i think.

I still think you're on track to get 6-8 inches.

:yikes: If this happens i guess its just not are yr..

New information about the upcoming storm. How to break the news lightly…the sleet line is going to advance all the way into the Mohawk Valley tomorrow morning during the peak of this event. What does that mean? Well, we still anticipate accumulating snow on the onset, but we’ll lose out on accumulation with the transition. This lowers the overall amount of snow we’ll see for this event. Snowfall map coming soon
The 540mb thickness line comes in between 5AM-9AM in the Mohawk Valley, where an estimated 0.5-7” of liquid occurs. This is essentially ‘lost snow’. Several inches of snow are still expected, but the foot plus totals look to be in the Adirondacks./quote]

That RUC model is 23 hours out..the best snows are going to be from 4 AM to 10 AM--- that warming comes after. I do think near the NY state line--3-5 is more likely with 4-8 the next level and 12+ north of ROC to SYR.

RUC tends to be more NW as well...and sucks at 24 hours. But, its likely valid.

I don't think sleet here will be much of a factor in terms of accumulations. The heavy intensity during the main WAA burst will lead to snow - and sleet if it occurs will be as it lightens in intensity late morning/early afternoon. We are essentially looking at about a 10 hour fast event where the bulk accumulates...

I think some people were thinking epic amounts would occur, but this is not a Noreaster..its Midwest storm where we get a nice warm advection snowfall. I still feel on target to get 12"+ total. Almost 5" fell today so I need 7" tomorrow. I'm thinking about 10" here tomorrow.
