Hey everyone, it's been a while! I wanted to share with you that the State Climate Office of NC has started posting new blog entries on NC weather and climate news.

I thought you guys might find their latest entry detailing how Siberian snowfall may impact the AO/NAO a good read. It's part of a series detailing different winter forecasting techniques that will end next Monday with their Winter 2012/13 outlook.

October Siberian Snowfall May Shape NC Winters: http://nc-climate.nc...limateblog?id=5

That's very interesting, thanks. I knew there was a known coorelation in the rate of October snow growth in Siberia and the eastern US cold, but I was not aware they actually created an index for it. I also did not know it's been used since 98-99 and from the chart, it seems very accurate. I'll be very interested to see what this index calls for in regard to cold this year. It really does seem to have an accurate track record even though it's only been used for the last 10 years or so.

The October Snow Advance Index this year was quite high. Not as high as 2009-2010, but not far off...and the AO is off to a negative start for Dec.

Just to clarify, the index was high this October, but in the graph where they compare the AO to the Oct SAI, they have to reverse the sign of the SAI, so that it is a better visual representation of the correlation.

Welcome Back I've always enjoyed your posts.

One good thing to note though it's far off is that the 12z continues to bring a system in around the 22 - 24th and on this run is a very good look for snow in the Carolinas.

The 12z in the LR is a fantastic look especially out to about 300+ you have real artic air starting to head south with systems rolling through the SE. If the Euro is still board we should rejoice at this.

Too bad it's so far out. It'll probably change every day between now and then.

12z system with cold rain for the majority of us is exactly what it think will happen. Path of low will not be east of the mtns but take a inland or somewhat coastal track. Regardless, not enough cold air to get into the action. Bring on Christmas! Although I'll be in WV for the majority of the holiday, figures!

Time to move the field goals...

The first system next week might just be setting the stage for the good stuff. From the discussion thread...

I'm also in agreement that this first storm in the 12/18-19 range could really set the stage for a legitimate southern US winter storm threat in the 12-23 to 12-25 period. There is certainly no guarantees in the timing of individual short waves at 10 days out, but the 12z GFS looked legit in it's setup for the 12/23 event.

Just saw this from WxSouth on facebook.

New European run is doing what the GFS did a couple days ago, creating a Very strong Southeast Storm that looks to head up the East Coast. Rain and thunderstorms Southeast, turning to snow Tennessee Valley and Appalachians, perhaps Damming in the lee side of the Apps , with pressures dropping to 984 mb in eastern NC. Looks like an impressive storm, but not cold initially, so primarily rain storm that could end as snow. **edit...By Wednesday midday (1 week from now) the pressure has dropped to 976 in eastern VA and southern Maryland..Big time blizzard in the Apps with that track and strength if this run is accurate.
