Tuesday/Wed Potential Brand new : )

Given the extensive snow cover in place and strong CAD signal, as well as the trend on all models toward lower heights/more confluence over SE Canada and Maine, I would expect the secondary to develop near the NJ coast and head ENE to the south of LI, not move bodily over New England like many of the GFS ensembles are indicating. The ECMWF ensembles have been consistently supporting this further south track for several runs.

There is the potential for a very significant ice storm for interior areas from northern NJ to the lower Hudson Valley and CT, and possibly even NYC itself. The one saving grace will be that there will likely be a significant break between the initial overrunning precip. and the batch from the main storm, and the precip. from the main storm will last only about 8-12 hours.

06z NAM appears to be coming in slightly colder/further south with the Tuesday thump. stronger high pressure across the upper Midwest, at 1056mb at 54hr

FWIW, and maybe not much but 06z NAM has joined the GGEM camp, maybe even exceeded the GGEM, keeps 850 0c 75-100 miles south of 00z, looks to stop in northern Westchester, weaker primary (by 8mbs) that pops a secondary south of LI at 84 hours, also has1028 mbs north of NE, 00z had that high at 1020 mb, appears NYC remains all frozen on this run but not all snow, however, if this is the beginning of a trend....but who's to say, only reason I'm looking is damn insomnia

By the way, great SPS from OKX:

AFTER SEVERAL SIGNIFICANT SNOW STORMS OVER THE LAST COUPLE OF

WEEKS...A DEEP SNOWPACK REMAINS ACROSS A LARGE PORTION OF THE TRI-

STATE AREA. A GENERAL 10 TO 30 INCHES OF SNOW DEPTH REMAINS ON THE

GROUND...WITH THE DEEPEST SNOW DEPTH VALUES ACROSS CONNECTICUT.

3 TO 5 INCHES OF SNOW WATER EQUIVALENT IS IN THE CURRENT SNOWPACK

ACROSS THE AREA. THIS RESULTS IN A TREMENDOUS AMOUNT OF WEIGHT PER

SQUARE FOOT.

THERE HAVE ALREADY BEEN REPORTS OF COLLAPSED ROOFS DUE TO THE

WEIGHT OF THE SNOW...AND WITH THE THREAT OF YET ANOTHER

SIGNIFICANT STORM SYSTEM EXPECTED DURING THE MIDDLE OF THIS

WEEK...NOW IS THE TIME FOR RESIDENTS AND BUILDING OWNERS TO TAKE

PREVENTATIVE ACTION TO SAFELY REMOVE SNOW FROM FLAT ROOF

TOPS AND DECKS.

im new to this and im looking at my area (central nj), but im seeing some dusting-> little accum on tues and then ice->rain on wednesday.. the potential for ice is, at this point, definite whether it be after the snow or in lieu of it.. im assuming the nam is over intensified dropping the low to 992.. liking the gfs as a balance to the nam and the euro.. once the low leaves land i would expect another dusting -> little accum of snow..

first post so im looking for some feedback- thanks

NWS bing in their AFD paints an ominous picture for us NEPA folk about a signifigant ice storm tuesday night into wednesday. Calling for widespread freezing rain after 4-6 inches of snow if I read it correctly.

Monday Night: Snow likely, mainly after 1am. Cloudy, with a low around 13. Light east wind. Chance of precipitation is 60%.

Tuesday: Snow before 1pm, then snow, freezing rain, and sleet. High near 24. Light east wind. Chance of precipitation is 90%. New precipitation amounts between a quarter and half of an inch possible.

Tuesday Night: Freezing rain. Low around 21. Chance of precipitation is 90%. New precipitation amounts between a quarter and half of an inch possible.

Wednesday: Freezing rain. High near 28. Chance of precipitation is 90%.

I know most of you guys are metro folks, but there's hundreds of thousands of people in wilkes-barre/scranton area that may have a bad event on the horizon...

at least it's snow first then ice...not the other way around...still bad, could be a lot worse.

6z NAM has the low exiting the southern NJ coast, with colder air 35F or lower trapped to the north of the track, precip is by hour 84. As it is, N NJ/NYC would see 1" of snow, than some sleet/ice, ending as a cold rain.

But a 50 mile shift south and the picture would be significanlty different. Places as close of Peekskill/Poughkeepsie are mostly snow, and 100% frozen/freezing. Going to be close...

NYC is definitely on the fence, IMO with round 2. Philly is pretty much going to get above 32 at some point but they'll probably have some icing to deal with Tuesday night. NYC may get more freezing rain out of this.

6z GFS is a nudge colder compared to 0z as well.

Current Wxsim program with the 6z models has a good front end thump for the NW Philadelphia suburbs (4 to 5") followed by a significant ice storm (0.50" qpf) and then a significant amount of rain (around 1.0") to top things off. Temps beginning to back off a bit but still indicates a high of 40 on Wed PM (kinda suspicious of that) mid 30s more likely here's the rundown

Snow arrives overnight by 3am Tuesday morning temp 22.5

Snow gets moderate to heavy during the afternoon with 4-5" of snow by 7pm

Then a gradual change to IP then ZR for most of the night.

Temps get above freezing just after 7am on Wed morning

Current Snow depth here 19.5"

I'm still not buying ANY model solution at this juncture.....0Z tonight at the earliest, and probably later than that, we'll start to get a better idea of what will actually happen. Funny though, how everyone seems to have put this one to rest and moved on already. You would think after the way this year is going people would know better by now. What is interesting, is that the models seem to be getting little by little colder lately.

Even IF the precip changes to plain rain Wednesday afternoon by Wednesday evening the below freezing temps return and by Thursday morning temps are once again in the teens across NYC metro - which will mean flash freezing -

so to recap its several inches of snow Tuesday - freezing rain some time Tuesday night - possibly a period of heavier rain Wednseday changing to snow showers Wednesday night then temps crash and all the slop freezes solid- what a mess - Thursday morning would be just as bad as Tuesday and Wednesday regarding travel conditions...........really no where for the liquid to drain with all huge snow piles blocking storm drains on the road...

For those interested JB tweeted this AM that the storm #1 tracks from Texas to Erie PA before 2ndry reaches coast...heaviest snow north and west of last few with ice a problem....#2 this weekend tracks up the coast and hits the places that have been getting it all year and the mid-atlantic too.. Plus big cold between the 2

I'm envisioning a 2007 situation with a sleetfest...I don't buy the rain solution the way this winter has been going...Regardless, I have a bad feeling about ice! Will definately be cranking up the heat starting Monday night in case we lose power for a few days.

Hi DSS

Not really the same situation....this looks like very shallow cold air near the surface so ZR very likely over and IP problems...fortunately I have an automatic generator that will kick in if need be.

Take care

Paul

The Valentine's Day 2007 storm has been a frequent analog with the current synoptics as shown on the CIPS website.

I was just going to ask about the analog for this storm. The only thing different about that storm were the temperatures.They were much colder in that storm than what they will be in this storm.
