FEB 13th-16th Snow, Ice and Rain

Wow VA got quite the ice storm warning, 0.25-0.5 locally more. Its crazy how much of the US has had severe icing past few days.

GFS not budging on the off the coast solution

With the track the GFS had it would have been a lot of snow for the area. The issue is the boundary layer didn't get pulled down far enough from the departing storm so we were left with a bad antecedent air mass. The departing storm meanders and doesn't pull the boundary layer down. It's definitely not an impossibility that snow occurs with this. I think we need to see the other wave move out faster and pull the colder our down.

But you can clearly see how serious this ice threat potential is.

The ice nudged north a bit too, i forgot who said they thought the ice would be more north, was it mugs?

GFS and NAM show sleet from CNJ, the shore and LI tomorrow around 4-8pm.

The Tuesday storm appears to be trending a bit colder. I still have a gut feeling N&W of NYC gets hit pretty hard with snow. That means there is a sleet/ice threat for those just N&W of NYC and NNJ. Let’s see what transpires tomorrow. Very tricky forecast

MOG GFS is WCS.....





if this happens verbatim the tristate will be at a halt for who knows how long. The frz pushed north just as stated, if it pushes any further north no one on this board will see snow, even on this one almost no one does.

Thoughts on Monday AM icing area if any?

Thankfully, as of now, the Jersey Shore looks to have minimal winter impacts from this storm beyond today. But today could be a bit of a mess. Not quite sure what to make of this hourly forecast. Hoping to get in another few hours of snow fall maybe, before the slop and rain set in?  Gonna salt real well today for sure and plan to stay off the roads once that frz starts and just hunker down (had to look that up, hunker or bunker? apparently, there is no such thing as 'bunker down' unless you hit it into the sand trap- lol).

If I'm reading these maps right, I guess this is a pretty understandable recipe for a freezing rain/ice storm (for 3 pm today):

Freezing at higher levels (500mb and 700mb):





NOT freezing closer to the surface at the 850 level:



And then freezing again at the surface:



Hope that warm nose backs down, but no one seems too hopeful of that...

The largest ice threat for Monday night and Tuesday remains EPA, NEPA, LHV and NW NJ. Models have trended warmer and every little bit will help with the severity of the threat. Nonetheless significant to severe icing is possible in those areas. I don't think coastal plain or the immediate I-95 will have significant icing, but maybe some though.

I can see some ice glazing today in the coastal plain. I think further north and west you go it's more sleet and possibly mixed with a bit of snow.

Yea, this is definitely trending warmer for the coast and N&W, which means N&W is now in the “ice threat” zone. But if this keeps trending we’re all looking at 35 degrees and a plain rain.

That would be my wish actually.

What happens with the first two impulses of energy will determine where the Boundary layer sets up.
And what the HP does over Canada. Any slight shift will change things for our area- ice to rain, all ice, snow n ice etc.
Tricky forecast.

Convinced now- Ray is the Mush !!! Hw comes in here after we had a great stretch of winter wx and what looked like a MECS is going to pot!
Luv you Raymond LOL!

Are we voting to ban him?

NAM makes me sad

So are we now just getting rain for tonight into tomorrow as well as Monday into Tuesday? Just wondering with all the confusion from the models. Will it be safe to be on the roads tonight?

GFS and NAM put us out of the picture for snow and any ice concerns with lovely rain to wash away all our nice snow.

Want a irish car bomb? That will make you forget what you have seen. It does suck, I know it was said snow threat is not gone but do these models shift back several hundred miles SE to bring it to where we can snow> Doesnt look likely to me.

Am I good for today and tomorrow, I am confused as there is a WWA for the bronx but not here and thats less than miles from me, is it really going to be that sharp of a cut off for the inch of snow and .10 ice? Or has upton just not pulled the trigger?

Not much weather is happening over the next 48 hours. The jersey shore, NYC and LI may see some sleet later today into early evening hours, but it’s very light and i don’t see it causing too many issues. The bigger storm moves in Monday but it’s looking like a plain rain. Models are struggling because they can’t figure out the block to the north. If there was a good block then we wouldn’t see the primary low cut to our west. It would do something like the Roodzilla storm where it attempts to cut but the block forces a transfer to the coast. In this scenario, there is a transfer but it’s way too late. That’s because the block is too far north and or weak. Check it out



Lack of 50/50 low and an Atlantic ridge that is expanding into the east coast. It’s a very bad setup for snow.

“ looking like a plain rain”... For the whole area?

from looking at the models and no analysis yes it looks like the majority of the area except maybe mickey P and Math.

Unless the Monday storm keeps pushing west, I think I'll do okay with that one. It doesn't look like anybody wins with that second system. Frank mentioned it earlier: that high is all over the place. What exactly causes such erratic movement in a high like that?

So it seems we should skip the generator check, but it may be a good time clear snow and ice from gutters and leaders pipes for the coming rain.

A fast freeze Tuesday night makes it even more important to get everything drained away as quickly as possible.
