Feb 17 Storm Disco I - looking like a POS special


40/70 Benchmark

Recommended Posts

The setup really isn't bad at all. Some key players there, but good God..look at 500mb. It's got shortwaves galore. However, a few tweaks would bring snow to Phil.

I know. What DT doesn't mention is that the Euro is keying in on a different northern s/w than for instance the 00z and 06z GFS did for its storm. There's a lot of energy pouring onshore in the west that has to be handled by the models.

One EXCELLENT trend is the tendency to split the vortex that forms to our northeast, with one lobe over Newfoundland and the other over the Great lakes / Southern Ontario.

In the weeniest of weenie dreams, this shows a few similarities to March 2001, should the Great Lakes lobe drop south ...

I don't know, 850's only briefly go to 0c here, They stay -4c for most of the storm friday

Yeah, the antecedent airmass is garbage by late week and there'll be decent WAA ahead of this. I think we will stay snow, but probably will def get above freezing by late morning Friday. The damage may be done by then, but I'm just sayin'.

But seriously, it almost does... lol

BTW.. I, ME, SNOWNH is starting the thread for this storm when I get home! I am the only.member to get a snowstorm to SNE this met winter... so Kevin Ray or BOB don't start one.

Starting to get amped

925mb temps look like they get to 32-33F for you on Friday, but you would be snow beforehand I think. Could be an isothermal blue bomb or close to it for you. Maybe just a bit more inland.

Right. It may be mashed taters all morning Friday with temps 32-34F. Temp profile below 900mb look like crap for most outside interior NW Maine and Extreme N NH

it also handles the srn s/w a bit different too. 00z might focus on another s/w, but I guess the overall pattern to me isn't that bad. I know we even touched on it yesterday, but there is still a lot of work to do if we want something of any consequence. At least NNE has the Friday deal.

Thanks Scott, Yeah, Not seeing 925's was my concern that we maybe borderline, But we shall see how it plays out over the next couple of days, Any snow is good snow

This is at least the second time you've reminded everyone of this.

First - No one cares gives a sh*t.

Second - What makes you think that the person who starts a thread has any outcome on a storm scenario?

Looks good for you especially if it trends a little better. This run probably even starts N ORH hills/SW NH with some snow, maybe 1" or so.

It'll be tough for anyone in the southern New England states I think. Even the valleys of southern VT and NH will have trouble accumulating more than 1" I think per latest data.

BOX doesn't seem to be ruling out interior snow yet:

THE QUESTION THEN BECOMES WHAT WILL BE THE FORM OF THE

PRECIPITATION. AS HAS BEEN THE CASE MOST OF THE WINTER...THERE IS

LITTLE COLD AIR TO WORK WITH PRECEDING THIS SYSTEM. WHILE THINGS

CAN CHANGE THIS FAR OUT...MAINLY RAIN IS FAVORED FOR THE COASTAL

PLAIN. HOWEVER...THE MODELS INDICATE THAT THE ATMOSPHERE MAY BE

MARGINALLY COLD ENOUGH TO SUPPORT SOME WET SNOW ACROSS PORTIONS OF

THE INTERIOR. WHETHER THIS COMES TO FRUITION WILL DEPEND UPON THE

EXACT TRACK AND AMOUNT OF FORCING/DYNAMICAL COOLING THAT OCCURS.

THIS IS OBVIOUSLY UNCERTAIN THIS FAR OUT...BUT SOMETHING WILL NEED

TO KEEP AN EYE ON.
