We are in a slow change pattern time and as we move towards Christmas week we will have SOME cold air around and some storms.
What does this mean?
Those of you who are on social media have likely already noted some posts discussing possible storms on Dec 20-21 and a follow up December 25 or so.
Dec 20-21
The Euro has been consistent with showing an event that stays to our south, times just enough cold air and holds it JUST barely and we get a pretty nice pre Christmas storm. Now, if the euro is exactly right we'd have a NICE mix to snow event with accumulations north of 460 north of 6 inches, with 2-3 inches down to the NC state line. If the Euro is exactly right.
The biggest thing that always happens is UNLESS the confluence (Air moving quickly behind a low that parks near 50/50) there will be a north trend. Models always tend to start too far south and trend north) Outside of a couple events.. FEb 2012 and Jan 2013, the north adjustment is real. If I had to target an area that is in the highest risk, I'd take the 81 corridor NORTH of Staunton as the highest risk, but extend the risk down the NC state line all the way east to the piedmont.
We are stepping slowly towards a colder pattern, but the real cold is still 3-4 weeks away. Just cold enough works in a perfect set up, but I'd not be too excited at this point. Everything would have to go swimmingly for us to see a nice storm.
Follow up possible Dec 25 or so--
The signs are there for a colder pattern early January but I'm always nervous at this point. DT from Wxrisk-- and many of you follow him has a good eye for these type events and he's updating a lot. He's a great follow for big ideas and patterns but when events get close, always stay with your local guys. Sean Sublette from WSET is fantastic. I say this often, but we are blessed with a skilled met who takes his job very seriously. For my people in Roanoke, Kevin Myatt is as good of an "semi professional" as I am (if not better) and if you know people in the NRV down to the Mt Empire, Zach from Blue Ridge Weather is a great resource. What skills that Kevin, Zach and I have are just great feels for the local climate and how storms would impact our specific region. I'd trust Kevin in about any event if I was unable to access model data. As we move forward, Wxrisk.com, Kevin from the Roanoke Times, Zach from Blue Ridge weather and let me throw in WxSouth with Robert Gamble are great resources for 411. Of course, stay with me for your local and precise winter weather updates. Even if the 21st and Christmas Day event don't pan out, things look to be picking up.
