Quick update-- is this legit?

Early evening thoughts--

This has the potential to be a very fun and memorable event. Doubt we set any snowfall records, (Maybe daily, need to check) but 7 inches falling in 4 hours would be good fun. 

However, tough system to track and as I've stated- even if it plays out on as depicted on the best models for snow, there will be winners and losers based on where the banding sets up. So, 3-6 outlook may see YOUR backyard get 2 but many others get 6-7. It won't be a uniform snow total. Banding isn't really modeled well- so that's another forecasting concern. 

Also, most places start as rain-- and it won't be that cold. So, some folks will start whining about the weatherman blowing another. I'd recommend following Sean Sublette and Jamey Singleton on FB and Twitter for other resources for current trends on the weather.

If it were up to me, I'd of gone warning region wide. 2-4, while very plausible is on the low end. As of now, All the counties WEST of the Blue Ridge are 4-8 and east are 2-4. Further, there are Winter Storm Warnings to our West and North, and watches to our south and east. To single out 4-5 counties East of the Blue Ridge is confusing and with the fast onset and potential for more, it's my belief it was the more prudent choice. With that, if we all get a couple inches east of the Blue Ridge, they'll look great.

Things that can go wrong-

This is being driven by that upper air low I graphed yesterday. The exact strength, track and speed play a huge role. If it ends up a tad weaker and faster-- we won't see as much. If it's a bit stronger and slower-- we could see a foot. The point being, while I am optimistic about this event there are more factors that we can't control in forecasting. So, if you want snow-- hope that ULL goes a little slower and stays closed (stronger) as long as possible. 

I'll do a full update later this evening with an actual map. Busy day tomorrow trying to work before the snow starts, but I'll tweet and FB all day as needed. I don't foresee any major changes in my 3-6 east and 6-10 west because I'd rather massage up if needed than forecast a foot and have the average be 2 inches. Just keep in mind that "potential" is certainly there.

Some of the snowier models kick the ROA and LYH areas to snow early afternoon. Be ready for bad travel, school closings and a general mess. 

The exact speed and strength of that "closed upper air low" is a  huge factor.
