Lurker on this thread, originally from College Point Queens, been working at NWS Chicago since 2010. Jealous of this storm, as it's been exceptionally boring out here and big snowstorms like Superstor

I think you’re going to see a correction back southeast today as the arctic airmass that’s building into the region throughout the day begins to get ingested into the models.  The temp drops thro

The high doesn’t mean much for how far the sleet advances. Those are mid level lows which determine that.

This needs to be repeated a million times for those who keep talking about surface temperatures and the track of the surface low. The mid levels are what will keep this from being a major snow event around the city, or not if the warm tongue is being overestimated which I doubt based on experience. Sleet almost always seems to advance faster than modelled around these parts.

Here's the dual-pol radar site which we'll be praying to, bargaining with, pleading to, cursing at, etc tonight sometime around NYC. Bookmark it and the game is that we avoid the yellow sleet line as long as we can. Yellow line-evil.

The sleet glaze and strong winds will make this storm more dangerous than had it been a plain snowstorm. 

So yes that line will be evil in more ways than one because surface temperatures will likely stay below freezing + we're heading into nighttime hours.

Somewhat torn on how much of an impact the mid level warming has on the immediate NYC metro.  Experience over the past several years tells me to assume it will be more than expected (a la NAM for this storm) so I will do just that if only to temper expectations. Will be happy with 7-9 here in Manhattan.

Sleet is annoying at the time but it also helps retain the snow pack for longer. Makes it much denser and freezes it solid. And yes just as slick to drive on etc as snow, just doesn't pile up nearly as fast. Sleet is 3:1 liquid ratio.

I have experienced sleet with temps in the teens. Talk about frustrating. Now I’m in Dutchess so I should be sitting pretty tonight.

Just to throw this out there... Does anybody remember the Valentine’s Day storm? All sleet. Awesome storm. Stayed around for a long time.

All of a sudden this forum that likes winter weather is so anti-sleet. You get a few hours of snow and several hours of sleet and you are in winter storm nirvana because that snowpack isnt going anywhere for a long time

It's brutal. Even in Jan 2011 it turned over fairly quick, but we had about 5 inches already. The main show arrived after it switched back to snow. I'm not confident it's that kind of scenario this time based on what I've been reading here. 1.) sleet arriving faster than expected in the mid-Atlantic and 2.) warm air aloft during the storm and 3.) possible shifts to easterly flow at times. I have been criticized here ( fairly ) but I have seen sleet both arrive faster and advance much further than forecast more than once.

Well that was just plain sleet for the entire storm in these parts. And really nothing much else that whole winter. PA and far NW had all the snow. This may be similar but coming at the start of the season isn't as heartbreaking as coming near the end after a prolonged snow drought....

I think had 7" of pure sleet it was insane.

Absolute nightmare on the roads and trying to shovel that crap.

Majority of snow falls before a quick hit of sleet on the coast.

When have you ever seen a low hug the coast that far North that resulted in a "brief period of sleet"? As depicted, warm air in the mid levels would fly North way before that frame. Better chance of an ice storm there with the stronger high than snow
