18Z Euro AI looked very promising for accumulating snows on Sunday into Sunday night as a wave develops after the front passes on Saturday. 

It shows a similar scenario as the 12z Euro for the mid week storm. We have a coastal low arriving from the south, surface temps are below freezing, but we are above freezing at 850mb.

Wild run to run differences. Need to first figure out the weekend wave before getting a handle on the 21st/ 22nd.  All potential outcomes are there are depending upon your preferred model run. Pretty crazy. Interesting part is this weekend's situation is not close to model consensus and it's Wednesday already.

Getting a strong high pressure (1040-1050mb) in the right spot, say, over upstate NY, certainly helps. Oh, and a 50/50 low around the 40/70 benchmark.

Don't overlook the potential of snow Sunday evening. Both the GFS and Euro highlight this possibility, though to varying degrees. It all depends on strength and where the band forms but some lucky spots could get some minor accumulations. 

Here was the 6z Euro. 12Z GFS is just starting.

Mid week threat is suppressed and OTS on the GFS, but has a 3rd threat next Friday into Saturday. 

Thank God. Far  better than the rain it was showing at  6Z. Maybe sunday will finally  be a win here

I need this in case next week is a bust haha

It will be interesting to see how the short term models perform as we approach the event in the next 2-3 days. Hopefully the axis of the heaviest snows is similar to what the 12z GFS run depicted.

@RIC AirportI need help with timing for Sunday it looks like it won't start possibly in until noon is that what you see? For Richmond,/Glen Allen area

as it stands now obviously

The latest GFS indicates a transition period from rain to snow between 3-4 PM and lasting until about 3-4 AM. In contrast, the Euro model suggests an earlier changeover, starting around noon and continuing until ~7 PM. The Euro is less aggressive and shows that the heaviest snowfall will remain north and west of Richmond. As you indicated, could be slight adjustments with the times from run to run, will need to monitor short term runs as we get closer.

EPS Mean for early next week. Wouldn’t take much to trend north with no real block in place

EPS mean for late next week system

Both Richmond and Norfolk have some good hits on the EPS charts.

You can see EPS likes the 22nd-23rd the most, and there is the threat around the 26-27th popping up as well.

It's time to start talking cold. Both the GFS and Euro show that RIC and ORF will remain below freezing for three consecutive days, while the Euro model indicates that both stations could stay below freezing for four days next week. The last instance of three or more consecutive days with high temperatures in the 20s or lower at both stations was in January 2018.

Additionally, RIC has the potential to dip into the single digits for the first time since Christmas Eve of 2022. If this occurs for two nights in a row, it would be the first time this has happened since January 2018, when RIC hit -3°F.

 

 

12z Euro temps valid 1pm Tuesday 1/21 showing RIC at only 16°F and ORF 19°F.

12z Euro had RIC at 7°F at 7am Wednesday 1/22, ORF at 17, thanks to the warmer water keeping temps elevated depending on wind speed/direction.

The placement of the band continues to shift, but still worth monitoring.

Avg of ICON and GFS is  2-3 for everyone. Once again after a cold day the warm surges  in and rain it  is for everyone for storm 2

I don't think the mid-late week, whether it's one or two systems, is resolved. There is enough confidence in snow Sunday into Sunday night, but who sees the accumulations, and how much still needs to be resolved. The placement of snow as the low departs the area varies from run to run.
