Blizzard of 2016 - Official Obs Thread

You know, we are doing this for real, man short on this formation, but we are epicenter into the thick.

 

Going with 27-28" storm total with widespread 3' drifts and scattered pockets of a lost yardstick.  I was in DC for Snowmageddon, DuPont Circle area, and this was more snow.  The one thing that strikes me this go around was the wind (and gravity waves on radar), even removed here west of the city inland, the wind this afternoon and tonight was big time.  Snownados were common, Moon is out, neighbor just cleared out lifeline out of here with a 70k tractor.  It took him several passes up and down the road, couple hundred yards at a time, but we have a means out.  This was his third clearing of the 1.5 mile back to the 400.  First was last night around midnight, est 8", then this morning around 9, add another 8", and then just now, I had 12" on the rd before he passed.  522 south to CHO should be fun in the morning. 

 

Have to hand it to the American Suite, namely the North American in picking up the NYC ban hammer inside 72hrs.  While the Euro was short stroking central VA, the NAM lead the way with the GFS right behind, these big dogs always come NW inside of 48.  Understand the cutoff was sharp, here too.  30 miles to our north there is 40".  But this is big time,  regions wide, enjoy MA/NY gents, jeb walks are for real this evening. 

 

SE weenies who want a sled, line up, selective screening is underway but the t step for this one in 20+, that's years...

We picked up a bit of something frozen (sleet? refrozen melted snow? ice pellets? it bounced when it hit, anyway) all the way down here near Savannah yesterday morning.  Didn't last long and only stuck around for a couple minutes, but still...

Can someone tell me what the dynamics were in central NC between about 5:00 and 9:00PM Friday? Was that when the gravity wave came through? I'm trying to figure out the correlation between the zr stopping, winds suddenly gusting to 30+ for about 2 hours, and a majority of the branches falling, causing the power outage. Yeah, things continued to snap off and on all night long, but most of the tree damage around here was between 5:30 and 7:30 or so.  There was about a 4 hour lull in the precip, temps remained steady at 32°. Freezing drizzle/rain resumed about 9ish.

I think it has to do with dryer air maybe, these are the obs from PGV that night.....in our case it was the heavy rain band that had winds steady in the teens gusting into mid 20's.....as soon as the sharp cutoff of the heavier rain moved east we saw a jump in the winds for a hr or so with gust to 40 and better...it also cleared out with a filtered moon visible and the low level clouds were hauling ass, wake lows are caused by sinking air that is higher pressure immediately following bands of storms/heavy rain...your timing matches it picked up here around 8pm that night...

All NWS GSP Storm Reports from the Winter Storm are showing in a sortable searchable workbook.

 

Our forum does not allow attachment of excel spreadsheets so you may access a copy here:

 

http://wnharrell.com/shared/KGSPJanuary2016WinterStormReports.xlsx

 

Note the 2 largest reports in the KGSP area are 18" and 19".

 

I do not see where Mount Mitchell was logged as a Local Storm Report with their reported 60" total accumulation from the storm.

 

 

You can also find this same data for other NWS offices at this link:

Wow.

We got blasted, most snow I have ever seen. About 30hrs of the accumulating type. Going with 28" storm total on the farm. I was in DC in Feb 2010 and this was more snow, and wind. Thigh high in the pastures and drifts deeper that the yardstick. Almost to Richmond, should be in PGV by kickoff. Benchmark has been set, maybe we can do some epic crush job in the Tughill one of these years, but this is going to be hard to top.

Interesting. Portion of my county here in the NC foothills got 20 inches. So not far off at all. Fun to be a part and track such a historic storm!

Wow!  Maybe somebody already posted this. Mt> Mitchell with 66 inches of snow!  

 

http://www.citizen-times.com/story/news/local/2016/01/24/mount-mitchell-digs-out-66-inches-snow/79262838/

 

Mt Mitchell picked up 66" throughout the storm. 

 

41.5" on Saturday alone. 

 

The Mid Atlantic cant touch Mt Mitchell with their 25 - 35" totals, but then again, no one east of the MS river can either. 

 

That's crazy high! In fact, that more than breaks the old record of the highest recorded snowfall in Mt. Mitchell (and NC, of course) set during the Superstorm of '93, where they recorded 50":
