LOL, I really like how the 12z GFS is depicting the change to a colder patter after day 10........and I like the fantasy storms as well :P

Looks rainy :( 

back on topic: 12" snowstorms are hard to come by at GSP. I believe the last one was The great southern slider of 88' which is why we cherish our 6" events around here. Ceasers Head saw 29" in February of 69'

this might be a once in a lifetime set up... we all might set records (given mine is 28” in the Blizzard of 73, that’s really saying something).
Doubt we set one here. Officially KECG is 25" March 1980. Our home at the time was 32" in southern Camden County with the same storm. The next highest is 17.5" which fell two weeks prior to that in February 1980, two days after my birthday.

I hear you Orangeburg. My top snowfalls are:
17/ Feb 2004
15/ Jan 2000
15/ March 1993
So since we are breaking records this winter; just once I want to expierence a 2 Footer. Think Frosty had a 19 inch couple years ago. Jburns had 19 on that Feb 2004, Raleigh think had 22 in Jan 2000. So Im not alone in a quest to join the 2 foot club. Not sure anyone was around down east in I beleive spring 1980 they where right at 2 foot mark.
I was 10 years old for that storm. We had 32" at our house in the south end of Camden County. Two weeks prior to that we had 17.5".

Fraz or Falls, Can you tell from the LR maps if that fantasy storm has cold air avecting into the region, retreating, or is just fropa? 

That's rain changing to snow. So cold air overtaking the system with perfect timing; which we know is usually an issue (...and is 11 days out). The most important thing about the 12 GFS is the pattern that it show for the LR. We have to try not to look at the fantasy storms that should start popping more in the coming days. **but we will look...

28" is so impressive for SC. ORF's daily record is 17.5" back from the 1890s, I believe we've never cracked 15" afterward. Maybe during the Blizzard of 1989, but I'll defer to people who know more. 

I do miss living in SE Europe, Dinaric Alps are indeed a beautiful place. In some spots it's a 15 mile drive from 0' to 5000-6000'. Going from sunbathing at the beach in the 60s to 10+ feet of snow and subfreezing temps in less than an hour really is incredible. 

Anyway, back on topic. I like our prospects for Feb, the indices are falling into place. Looking at the 12z GFS, cold rebuilds in Canada by the end of the month and then overspreads the country east of the Rockies by the end of the first week of Feb. It would be nice to score sooner rather than later considering increasingly hostile climo in this neck of the woods as we near spring.

Yeah that look is going to change a lot between now and then. Point is there are going to be some good shots at another storm or two.

The MJO has received a lot of attention lately with respect to the upcoming pattern, and rightfully so.  The active MJO phase is currently located over the eastern Maritime Continent and Western Pacific (seen here via -VP anomalies in blue & purple; -VP measures upper level divergence associated with tropical convection).  Source for this loop: http://www.atmos.albany.edu/student/ventrice/real_time/maps/mjo/global_analyses.html

The strongest tropical forcing (-VP forcing) of this winter was recorded in that region just last week: https://twitter.com/MJVentrice/status/955430819581059072

 

MJO > Mid-Latitude Circulation theory suggests that the potential for western ridging and eastern troughing will go up once these -VP anomalies move east into the Eastern Pacific and continue east thru Africa.  See Mike Ventrice's AMS Conf Presentation for more info: https://ams.confex.com/ams/95Annual/videogateway.cgi/id/29036?recordingid=29036 

 

The CFS forecast moves the -VP anomalies into the eastern Pacific in the Feb 5-11 timeframe.  From there, the MJO would support, say, a 3-4 week window where periods of western ridge / eastern trough are likely.  Source: https://ncics.org/portfolio/monitor/mjo/ (the term "CHI" here = VP Anomalies; green is -VP)zKGstHm.png

 

Today's EPS Mean has a western ridge / eastern trough at day 15 (Feb 6)

The pattern of northern stream dominance, typical of La Ninas, and especially 2nd year La Ninas, could continue as the subtropical jet has been notably absent thus far this winter.  Note the blue shading along 20N - 30N just NE of Hawaii and extending east into the Gulf of Mexico, indicating zonal westerly winds at 250mb that have been weaker than normal so far this winter.0rmSAi5.png

New rule!!

No one under 50 years of age may say, "this might be a once in a lifetime __________". 

Damn kids.

Euro Weeklies come in pretty much as expected.  Has western ridge / eastern trough pattern beginning in week 3 (Feb 5-12) and continues through early March.  +NAO.  Looks northern stream dominant like we've had most of the winter.  Precip is below normal weeks 3 to 4...near normal thereafter thru week 6
Do we trust the weeklies? They haven't been that great this winter.

Yes Sir I did get 19", 11" of it was in a four hour period. Beat all I ever seen that morning 4 inches in one hour!!! I doubt I'll ever see anything close to that again, but it sure would be nice to have a run at it.........................................

They've been fine from what I've seen. They were too quick to warm things up in Jan, but we're in it now

Pretty much everything you can get your hands on shows it cooling down in early Feb.  I’d give the Weeklies some weight.  I wish they’d be a bit more robust with the STJ, but we can make well-times northern stream stuff work out.  Looks like some stout cold near the end of the 18z GFS run.

You received more in that storm than we did up in Pine Ridge area. We received 15. I`m not complaining though. 

Biggest storm I've seen was January 1996 when we received 18 in.

I'd love to see another one 15" or 19", I'll be a happy snowman!!! I do believe some parts of NC  will see a biggie before spring...................

Yep, I just want to set another snowfall record here before I pass the torch. 1988 and 1969 both saw greater than 15 inches of snow. We have had plenty of 1 footers. I am still holding out for the elusive 20" storm. Could this be the year?
