If you refer to my blog from November 11th, I stated that the best shot of snow was going to be Thanksgiving week, and dangit if I wasn't right. On what is the busiest travel day of the year, if this thing reaches potential it's going to be a miserable travel day and I'd suggest anyone with family travelling from NC north to New England start to have alternative plans with leaving early or later than planned. This won't be a BLIZZARD but Wednesday may be a bad travel day with many cancelled flights, etc. I'm supposed to be driving to my mom's in Rehobeth DE, and think as of now we won't hit the road till Thursday AM.
The personal torture for me is that my home internet is acting up and I can't get the maps to load..I get a drip of net service that gives me SOME FB updates and chat. I'm currently at McDonalds eating pancakes and using their net service. (And I live in the ONE and only bad cell data spot in the city of Lynchburg so my ipad and cell are useless too)Cable service will be out tomorrow to fix it, but it is taking my competitive advantage away compared to other forecasting outlets. I'll be somewhere late afternoon where I can hop back on line and comb through the data.
I always write from the perspective that snow is a good thing, and despite the holiday we are NOT changing our format.
Basics- Storm moves in after midnight, towards morning-- 3-5 AM time frame and will be rain or rain and snow mix. At some point it flips to all snow and accumulates nicely. IF we can slow this thing down a few hours our snow totals go up. if it speeds up, the cold air doesn't have enough time to get in place and we get more rain.
Initial thoughts are we see 3-5 inches, with maybe 4-8 higher elevations especially west of BR above 1500 feet elevations. I think most places see .75 to an inch of liquid, but the start as rain with temps near 40 most areas and we bottom around at 32-33 most of the day. So, wet past snow all over everything. Get those christmas lights up early.
Can we get more?? Yes-- if the system slows down and the models are a tad warm as shown now. This is a rapidly developing storm and that's a very real possibility that we are at 40 degrees and an an hour we are at 33 with moderate snow falling. Think of March 16th this year-- we went from 48 and drizzle to snow in 2-3 hours.
Can we get less?? Yes-- the set up isn't ideal but the pieces work just well enough to give this threat. Any minor subtle changes would change the path and strength of the storm/cold will be huge.
You'll likely see some crazy snow maps on facebook and please don't feed the trolls, especially one out from the Euro. It's based on a 10-1 snow ratio and it simply won't be that good. Take those maps and multiply the total by .7 or so to get a legit number, and that is likely your upside. So, the EURO shows us getting about 10 inches, I'd take that as a 4-7 inch total for us. But, that's assuming we get an inch of liquid.
The Euro is leading the way,and it does usually on southern stream events (thanks almost el nino). The GFS has moved towards the EURO now, we are just waiting on the Canadian model and a newer version of the GFS (better resolution).With that, here is my first outlook. I'm way west of guidance because these southern stream events are ALWAYS way west. Feb 13th I was west of ANYONE else with guidance and I was still too east.
Here is a first stab at this-- COULD be way off and I'm running of some HUGE assumptions, mainly being this will be a strong system and the best bands will set up further west than modeled. That's a safe bet VERY often. If this was NOT a major travel day, we'd be in discussion mode, not making my lovely maps. :)
|First Guess.. use with Caution.|
I'll throw out some tweets and FB updates before I get full access with info as passed along to me.
If we max out, I can see LYH getting 6-8 inches and maybe 10+ on higher elevations of the Blue Ridge. Not a forecast but just a Worst Case.. with some lingering leaves, some power outages could start to creep in.
Lastly, big shout out to Nick-- LU football star and blog reader and the entire team on the exciting win yesterday. I moved here 20 years ago to attend LU and what a thrilling season. What a way to get the first FCS playoff appearance in school history. Proud of the team!!
