NEG NAO

I wish there were more METS like yourself posting in this forum to guide us through this potential for obvious reasons.........

glad you fully explained your reasoning

its the same out here in the suburbs on the side streets that are not snow emergency streets - they should have an ordinance that states you have to remove your plowed in car within a couple days but they don't - and who wants to have to stay home on the weekend snow bound ! Hoping for only a 2-4 or 3-6 max = sorry folks !

I don't think some people realize what a big deal this is going to be even if we only have a SECS with Arctic air in place and over foot of snow already on the ground - think about it - going to be difficult to plow and remove from driveways......

surprised its only 991 was stronger earlier ?? or was that other models ?

the ICON is a second string model at best - especially the OP version

BIG difference in accumulations from 50 to 150 miles if that is westward - doesn't make sense that there will be a hard right turn at Hatteras

and the kicker hasn't even been properly sampled that energy is still out in the pacific and the energy that will generate the trough in the southeast is still way up in Canada not properly sampled yet - so the storm right now is modeled to be right on our doorstep so expect changes as we get closer

doesn't matter how far west the trough is it has to turn negative sooner - if it stays positive the chances of the storm moving up the coast too far east increases

The key points to remember for today IMO 1. the key piece of energy that will generate the trough lalter this week is still far north in Canada and there is sparse sampling up there. 2. The trough down south later this week has to take on a negative tilt sooner than later and further west for this storm to get close enough to the coast to give us a major storm. If it waits to go negative further east the storm will ride up the coast further east. 3. The reason the trough has to go negative earlier and further west is because the upward motion in the atmosphere is on the northeastern flank of the trough promotes heavier precip and this will be centered over the metro if the storm is close to the coast and out to sea if it goes negative to late.

go back to 2010 here and research it -let us know

why today ? I think we will be spinning our wheels today with the ops and ensembles arguing with themselves and with others - one other thing need to get that kicker out of the picture and the trough to go more negative

post one

models are in windshield mode now - IMO won't be for 2 or 3 days till we get solution we can mostly believe but not totally

thats snowfall not liquid

The EPS from last night showed a few inches - what evidence do you have that it will be all or nothing ?

I don't even listen to them (all noise) - - only well known reputable METS - IMO have to keep all options open this far out

to refresh our memory what are some of his credentials and how did he perform with this past weekends storm ?

I would give it 72 hours at least - like the last storm no one is expectiing a HECS - a 2-4 or 3-6 is more reasonable IMO

you can tell the GFS OP is out to lunch because the GEFS has no huge snowfall amounts south of us like the OP does - treat the OP like one of the ensemble members.

EPS mean still delivers a few inches snow - ratio's probably higher than 10:1 - liquid QPF Map - don't have access to snow map

Progressive flow caused by that LP vort near Minnesota moving east BUT is it right ? See if the EPS agrees with the OP

The lp on 0Z Euro went from a 995 to a 983 stalled off NC coast in 6 hours - BUT 12 hours later deepens to 962mb moving east - weird solution and progressive flow that L near Minnesota is not a good signal with HP in southeast Canada - too far north

The EURO AI moved east from 18Z - this thing has to take on a more negative tilt IMO.

sounds like a flat roof to me - most of the sloped roofs lose the snow faster especially south facing ones
