TwcMan Posted January 18, 2011 Share Posted January 18, 2011 Hearing sleet mixing in now... that bright banding looks like it is the line of snow/sleet. I believe it is, once it passed over my area I switched right to sleet. Link to comment Share on other sites More sharing options...
Hailstorm Posted January 18, 2011 Share Posted January 18, 2011 The 950 MB 0* C line has advanced dramatically to NYC and LI: However, the surface temps of 32* F have not budged much over the past 2 hours: Link to comment Share on other sites More sharing options...
nzucker Posted January 18, 2011 Share Posted January 18, 2011 if we're seeing less snow than anticipated, this could be even worse. imagine if 1.00" LE falls, after only 0.15" was frozen... gonna be a fun morning! This is going to be a mess. SN/+SN here 21.8F Winds NE. .5" accumulation I really don't know how we're going to get above freezing at the surface here with NE winds and evaporational cooling keeping temperatures on the wintry side. Westchester could be in for a nasty ice storm, I guess I have to stay up. Just went for a walk, gorgeous flakes falling and streets are extremely slick.

Sn0waddict Posted January 18, 2011 Share Posted January 18, 2011 I'll say this...I was surprised that I am pinging this fast. I'm pretty far west in my county and usually don't flip for a while. But this is a different type of event..the WAA is working through the mid levels on a very strong sly flow. It's going going to slow down for much. Ya, I was shocked when i saw reports from you amongst others in your area that it was sleeting already. Then again, after looking at the radar it looks like the bright banding might have stopped advancing north. Link to comment Share on other sites More sharing options...

But this is a different type of event..the WAA is working through the mid levels on a very strong sly flow. It's going going to slow down for much. Yeah, I flipped to Sleet here about 2 AM with between 1.5 and 2 inches of Snow on the Ground..Funny thing is the temp has dropped to from 25 to 23 the past 2 hrs..The way it stand there could be SEVERAL hrs of Sleet and Freezing rain cause dangerous travel and even downed Power lines.. I am not forcast to hit Above freezing until 9 AM so Your talking another 6 Plus Hrs of Frozen Precip that is not in the form of snow.. Link to comment Share on other sites More sharing options...

SPC mesoanalysis had the 925mb freezing line advancing north quite a bit. Link to comment Share on other sites More sharing options...
ORH_wxman Posted January 18, 2011 Share Posted January 18, 2011 Ya, I was shocked when i saw reports from you amongst others in your area that it was sleeting already. Then again, after looking at the radar it looks like the bright banding might have stopped advancing north. I'd expect it to slow down at least for a bit as it goes north...the sleet in NJ and LI/NYC area is from a warm nose at 900-950mb rather than higher up like 800-850mb (at least currently), so the warmer air down in 950mb range is going to forced into the much denser cold airmass to the north and forced to rise as it heads north which will enhance any evap/dynamical cooling. So it wouldn't surprise me to see the snow/sleet line wobble nearly stationary for a couple hours north of NYC in the lower Hudson. We'll see soon enough.

What do you think about the icing potential here, Will? Is this going to get dangerous just north of NYC? I'm only at 21.9F! Link to comment Share on other sites More sharing options...

It's not like I'm expecting much snow out if this, but I actually think it would be rather interesting to go through an extended period of sleet/freezing rain. As for my observation, light/moderate snow. Probably .25-.5 here. Link to comment Share on other sites More sharing options...

I really haven't looked that closely at the ZR stuff down there, I've mainly been trying to keep track of the sleet/snow line as it goes north....but the ageostrophic component to the wind right now is really good out of the north (different from sfc wind) which really could mean it will take a long time to scour it out away from the coast.

NorthShoreWx Posted January 18, 2011 Share Posted January 18, 2011 Still all snow here, mostly light but steady. I went out and measured 0.5" about 2AM. Hopefully we have more on the ground in the am than we do now, because we are going to have less in the pm. I went skiing locally both days this weekend and where I had to break trail its still a lot of snow, even tried some tele turns in powder. I suck at it...need the heel clamped down, but it was fun. Under the foot + of powder was a hard icy base (no sign of rocks, roots, erosion control steps on trails)...sorry but we just don't get that kind of condition around here very often. I could get used to this. At least for now it's getting better before it gets worse during the day. The temp has risen to 27. I'm done working and am going to bed. Goodnight all.

earthlight Posted January 18, 2011 Share Posted January 18, 2011 Looks like close to 2 inches fell before the changeover. Not bad..that's 45" now. Link to comment Share on other sites More sharing options...
nzucker Posted January 18, 2011 Share Posted January 18, 2011 Looks like close to 2 inches fell before the changeover. Not bad..that's 45" now. What's the most you've ever had in a winter at your place? Should be good for like 3" at this spot in Westchester, snowing pretty heavily and accumulating nicely with the temp at 22.2F. That would put me at 35" for the season, and awaiting a big storm Friday. Link to comment Share on other sites More sharing options...

It was all downhill after that But last year was the best I have experienced at this place...I believe we finished in the mid to upper 50's on the year. We're on pace to blow that out of the water this season. Link to comment Share on other sites More sharing options...
earthlight Posted January 18, 2011 Share Posted January 18, 2011 By the way my official recording station is Plainfield..their best winter is 67.1" in 1966-1967..but I and locations around me routinely have higher totals when compared to them so I guess there is no way of truly knowing.

Hailstorm Posted January 18, 2011 Share Posted January 18, 2011 Not sure why my temp and dew point keeps rising here in Brooklyn even though winds are still coming in from the NE at 10 MPH....

CooL Posted January 18, 2011 Share Posted January 18, 2011 Heavy snow with huge flakes here, im probly just north of that sleet line if earthlight is all sleet right now. Wish it would stay like this all night, pretty cool storm. Link to comment Share on other sites More sharing options...
