Although there are still many signs that the heaviest accumulations will be north of Richmond. What are the signs that the heaviest will be north of Ric?

RIC Airport Posted February 8 Author Share Posted February 8 Also, @jlewis1111, although this is out in range for that model, the NAM, at least as of now, is favoring a north. But, all of this doesnt mean RIC won't see any snow. NBM lags behind a bit, but still has recent data is also favoring the heaviest being north.

I feel like the GFS OP is overdone After the dropsonde 0z Friday which was Thursday night into the GFS was when things started changing and we started seeing more snow would be to the south. Yesterday I made a call of 3 to 5 inches and I might be a little low with that now. But thermals are still iffy as far as good accumulation on the ground.

Euro has surface temperatures around 33-34°F during the event, so there won't be an exact 10:1 ratio. Note the difference between 10:1 and the Kuchera map I posted earlier. Hopefully, the heaviest bands will set right up over Richmond Metro, which could help temperatures reach freezing long enough for the snow to pile up in spots. Lighter rates will probably mean 33°Fvs 32°F. The best thing about this is that the precip is starting early in the morning, which should help. 1 Link to comment Share on other sites More sharing options...

Two things I will say about thermals: 1-Looks like the GFS is a little colder as forecasted 2-It seems for this winter season so far the models have had a hard time dealing with CAD. It's consistently poorly forecasted and we have been much colder than what the temperatures we're supposed to be. during that cold spell as we came out of it we would see predicted temperatures of 40° by 9 a.m. for example and it would still be 32° Link to comment Share on other sites More sharing options...

Hopefully it's correct. 1 Link to comment Share on other sites More sharing options...

TampaMan Posted February 8 Share Posted February 8 NAM looks way drier than the other models thus far. Also has a second batch arriving Tuesday night into Wednesday that looks to be all rain. Feeling very meh about this system right now. I imagine it won't be very strong. Link to comment Share on other sites More sharing options...

But, all of this doesnt mean RIC won't see any snow. 18Z NAM is getting within range and, so far, still favors the heaviest accumulations north of Richmond. Yes, it's the NAM, but I'm just showing another model for expectation management; we need the short term models to get more in line with the globals. Verbatim Richmond starts off as snow, but quickly changes over to rain. Precip arrival is also several hours later on the NAM compared to the 12z GFS, so that could be why it's warmer and less snow.

It's not "it's the NAM". It's the NAM outside of 36 hours. It's ok inside 36. Link to comment Share on other sites More sharing options...
