February 2013 mid-long range disco thread

Recommended Posts

All I've watched for all winter is getting enough of a W coast ridge to usher the clippers down our way.  We have seen that happen some and I would like to think we will cash in on one with some STJ assistance.

 

We sure have heard a lot of chatter from red tags around the board about how we are moving in that direction haven't we? But like Ian has said many times, the lr stuff is muddy at best. Too many moving parts to expect accuracy much over 50/50 for the most part. Some things are easier to see than others. I wouldn't rate the current progs as easy to see by any means. 

 

I wouldn't be surprised either way in Feb. A nice juicy ss low that actually dumps precip over cold air or a virtual shutout. You can't rule out either. Yea, the persistence thing goes a long ways but still. Every time I run the loops I see cold air nearby and/or getting pulled down by a departing low. The temps aren't the enemy as much as a quiet ss and neutral nao. We can overcome the neutral nao with good timing or a 50/50 but we can't overcome not having some juice work without the stj.

jan 2005 type storm again. Someone in New England would see 40 inches. We would see 3. Ill take it!

 

 

I think we can sneak something in that period ..perhaps wishful thinking...I know Wes doesn't like the pattern quite yet, so he'll probably be right

 

If we can get the split flow the GFS keeps advertising, we have a small window  to get something even with a bad Atlantic...it might be into a rotting air mass, but that could be serviceable in early February

Moon angle and road temps will ensure a dusting

 

Overnight tonight, some light snow is probable. Unfortunately will mostly fall when we are sleeping. See percentages below for immediate DC metro.

- No Snow - 30%

- Light snow/flurries fall but don't accumulate other than a very light coating on car tops, etc - 30%

- Light snow, 1/4" to 1/2" - 25%

- Light snow >1/2" - 15%

Feb 2006 was into a stale marginal air mass with a crap atlantic, but I will take my chances with some STJ energy and a split flow over what we have had the last 2 years anyday.  I can understand where the criticism saying that I only get excited when the stars align perfectly comes from but honestly, I can be interested in something that is only a marginal setup, sometimes they hit against the odds.  The problem is the last two years we have not even had that.  We have had non stop hostile conditions if you want to get a significant snowfall, even a 2-4" type event.  While I am not in love with the pattern evolving, it is light years better then what we have had.  The period from Feb 10-20th or so looks to have promise, especially if you look at the GEFS and what it is hinting at.  Its not perfect, sure would love to see a -NAO pop up, but its a pattern that we can get something if we get a little luck.  That is more then could be said for most of the last 2 years.  I am interested in mid February.

Sunday system is a little convoluted. We're in between lows again but who knows. Maybe something crazy happens. Not enthused but maybe we get hammered with an inch. 

 

Eastern mass is probably doing naked jumping jacks right now though. 

 

I like seeing snow fall and have no expectations for these weekend events, so I will be pleased even if we see flurries

Pretty much the same here too. At least they've never teased us with anything "decent" leading up. Any flakes will be nice and it one of them drops an inch then it's a smashing success in my book.

we are in a good cartopper pattern for the next 5-6 days....hopefully we get something to look at

 

Yea, no kidding. 4 distinct chances. Well, at least on the gfs anyways. Pattern is ripe for it. 

 

I guess the thing to watch is how each one evolves way up north. If the the flow gets carved properly we could have one of these take a nice rounded turn below us with some weak waa. I know it's a low prob situation but each approaching little system won't be fully resolved until the departing one is figured out. Makes for entertaining model watching if nothing else.

then the system on the 8th that keeps showing up is less than ideal unless the southern stream is stronger or we get a phase...rotting air mass....I know Wes doesn't like it and I don't think he has to change anything in his article...he will probably be right....
