More Heavy Lake Effect Snow East of Lake Ontario

6:20 AM Wednesday 1/23/2008, Dave Longley -  A fresh supply of cold air will bring more heavy lake effect snow to parts of central New York.  The areas likely to see significant snowfall will be across southern Jefferson, northern Oswego and Lewis counties.  The band will likely oscillate a bit north and south, and could affect the city of Oswego at times this afternoon.  Gusty winds will produce whiteout conditions.  Snow totals of 8-18" are likely within this band of snow by 7 PM this evening.

After 7 PM, the band will remain quite strong and should have shifted south into central Oswego county, but things will start to quickly fall apart after midnight.

We'll keep you updated here throughout the day.  Feel free to post your observations and snow totals.

-Dave Longley

I looked at the seven day forecast and it said that there would be heavy snow in SYR
on saturday. Is that lake effect or a coastal storm?

Tom,  not sure you saw that....we don't see any heavy snow for SYR Saturday.  Maybe a little light snow, and that's it.

Update at 11:45--18" of snow since 6 AM in Redfield from our weather watcher there.  Looks like good news for the Tug.

Core of heavy snow has sagged south just a bit, with some light snow in Oswego.  This may continue for the next little bit.  An arctic cold front now just north and west of Lake Ontario will swing down over the lake this afternoon.  This should make the lake snows heavier through the evening over Oswego, Lewis and northern Oneida counties.

Still looks like no appreciable impact here from that lake effect snowband tonight.  Winds are forecast to become northerly and eventually northeasterly and our thinking is that the heavy snow band now over Lake Ontario will move to the south shore of the lake and may weaken some toward Thursday morning.

What's with the predicted warm up? How long will it last? Temps holding in the 20's would be GREAT!

Looks like 40's - to maybe close to 50 right into February, which equals no snow, and no ice for ice fishing

but PS - the NAO looks like it might think about tanking after Feb 1st.

Dave - does this look at all promising to you - or just more hype?

I drove north on Rt. 3 this morning from Pulaski to Sandy Creek and couldn't see more than 100 feet in front of the car. So I turned around and headed home. Dangerous stuff up there today!

mchamplin - You're right, the NAO is showing signs of heading into negative territory.  We've been looking a lot at the AO, in particular the ensemble forecasts of the AO.  Check out this link, http://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/ao.sprd2.gif You'll see some members are negative, but there are still some positive members, so bottom line a lot of uncertainty heading toward early Feb.  One thing too, when you check out the PNA, it's trending negative too, so it might be tough to replenish arctic air in North America.  If we do get the block setting up in the central Atlantic, it might have some stale cold air to work with.  We'll see.

I wish I had a vacation home in Florida.  The overwhelming trend is for warmth in the SE US.  Also some much needed rain for ATL.

Dave, Florida is not all it's cracked up to be.  Born and raised there, moved after 30 years.  Traffic is horrendous everywhere now and it really does rain at 14:30 every day.  

Seasons are a lot more fun, and evident, up here.  But I can hook you up with a fishing guide or two if you want to head to the Tampa / Sarasota area.

9:00 PM Update....

The biggest totals we've seen from today are 21" in Lacona and 35" in N. Redfield. The N. Redfield total was from the same person who had 141" last February from the big lake effect outbreak.

Here's is some of our reasoning behind keeping up some of the big snow totals near the lake tonight. While temperatures at 5,000 feet remain unchanged throughout the night, they are cooling at 10,000 feet which makes for a more 'unstable' enviroment (better for clouds to form) and also there is a weak disturbance passing through overnight that should enhance the lift as well.  For those reason we felt the lake snows could stay productive.  The real trick is the wind.  It is dying down which, in theory, would allow the band to migrate back toward the lakeshore.  Our computer models this afternoon hinted at strong convergence (wind colliding down near the surface) along the south shore which is why (even it is only within a few miles of the lake) we extended the area of 12"+ all the way back to Rochester.  

Coffeeguy, anything from the Southern Tier to Albany Thursday will be light, maybe an inch or so and that would be it.  Watch for the wind to pick up a bit in the afternoon, though.

Light snow here in O-Hill right now.  Looks to be coming off of Lake Erie??????

Waiting to see if the "big" band makes its way down here later tonight/early tomorrow AM, and if it does, if it has any "juice" left in it.

Thanks Jim for the update!

Shawn said:

Forgot to ask you Jim, I read tomorrow there is going to be another shot of cold air coming in, and Dave E. points out that tomorrow night (Thursday nite), lake effect will setup Southeast of the lake.....Any big deal?

well at least this year is not anything like last year. This past Sunday nites storm was a rough one. I work in Liverpool and I left work at 12:30 am monday morning and didnt get home into Mexico/New Haven area untill 5am or so. That was after the fact of being stuck of Stewarts Corners Rd. in Pennellville and then getting stuck on CR 64 by OC BOCES. Oh yes one thing, thank you Pennellville VFD for letting me hang out at your station as the storm passed. It was appreciated!!!!
