Hey guys, brand new here and reading through the pages this forum sounds like fun and you all have really good info and analysis. Question and smack me if it has been answered but local mets in richmond discussing their RPM model and saying it is showing no snow for RIC and very little south of here. Anyone know why? I can't find that model anywhere.

The RPM model is run by a private company called WSI (Weather Services International), because it's private only those networks who subscribe to their service can view it. Weather Underground used to have it on their wundermap, but I can't find it anymore. I think Richmond is safe for some snow though... :)

Hoping to make a "schools closed" decision for Albemarle County (CHO) tonight.  This is a "forecast call" and I don't see any possiblilty of safely running 150 school buses for 3 hours during the afternoon.

Josh, flash freeze is a real possibility.  When it hits, it will hit hard.  Remember December 19, 2009 with the extremely heavy snow at the outset?  I'd play it safe, otherwise the parents will go apesh*t like they did for the hurricane.

Don't know about Charlottesville, but Dec 19 was much colder before and during that storm than this one will be in my area. I think the snow started here with a temp of about 26 degrees, IIRC.

True but I can also remember cases when the the gradient was really tight and they got 8 inches in Prince Frederick which is in the middle of my county and I got zilch living in the northern end of the county and I was supposed to get several inches.  Tight gradients can screw you lots of ways.  You can get under the deformation zone and a band that goes stationary and not very far way someone gets nothing.  That's the problem.  The fact that the higher resolution models seem to be holding the precip farther south is a concern at least to me. 

Of course! There is no doubt there will be a sharp cutoff as the ageo/secondary cuts off lift. But I was just saying if you get into the band/deform, these situations can easily bust with higher accumulations. This could end up being a warmer/weaker version of 1/30/10.

Thanks everyone.  NBC12 is the one that is stating the RPM model is saying no snow.  It is mentioned on one of their mets facebook pages.  Granted they did not change their forecast but since I can't find the model I was interested where it was coming from and how accurate it was.  Glad to be here and hope to learn from you all.  I think 4" is a good number also, but most of that will be on grassy areas.

My recommendation is on the table....now we need for others to "get to yes."  I was royally POd the last time "we" decided to go to school under an active Winter Storm Warning (2011).  It was a hair-raising operation when we finally called it a day (early dismissal) after the changeover to snow.

 

High school students are scheduled for exams tomorrow - think they will be able to concentrate with a snowstorm bearing down?

RPM and NAM share similar physics, if I recall correctly. Thus, similar 18z outcomes for our area.

What happened to the 2-2.25 it was showing for western nc earlier? This map doesn't show over an inch for anyone?

that was 24 hr this is 12 tho not sure if thats the diff. the timestamp also says the 17th.. toss it. :P

That SREF output is actually pretty encouraging after what the 18Z NAM showed. Recall, the new SREF is loaded with WRF members; the fact that the 21Z run did not follow suit with the 18Z NAM in going noticably drier for the DC area is encouraging. Still want to see more QPF farther north with the 00Z higher res runs though...at least one or two of them!
