84 hours from snow making it into DC and the GFS and Euro couldn’t be more different. It does seem like GFS took another step to the Euro (and as PSU pointed out, ICON would have been a Euro-like solution had the phase been cleaner).
I loved the WAA on both 00z models tonight though.
Through 72, the vort is stronger than prior runs which has been a big difference from the Euro. GFS weakens the vort as it heads east whereas Euro holds/strengthens.
So little data available with this model but it looks like 0.5”+ snow for DC from the WAA. Similar for Winchester. Seems like places south of Baltimore miss out on the coastal action just by looking at the total precip maps.
It’s such a wonky evolution. I like the WAA a lot.
It’s not a coastal rider. The SLP panels are on WxBell already and it forms near OBX then heads NE about 100 miles off ORF then heads NW from there and makes “landfall” at ACY.
There is no reputable model that is a total whiff or mostly rain. Even the “disaster” GFS is 3-6” WAA/dry slot or rain to snow showers on the back-end.
Yes, this is not locked in by any means to a solution but its hard to argue against the consistency of the EPS.
I do the same at Deep Creek....when I was there for MLK weekend, at one point I just laid down and looked up at the sky as the snow fell on me. I probably have a problem. Lol
The para almost takes the low to Chicago before it hits a brick wall and heads to OH. Basically transfers at our latitude.
4-6" from the thump, dry slot, then 1-3" from snow showers on Monday from the ULL
ICON has snow breaking out across the SW part of the forum ~1a and DC by about 4a Sunday. Transfer is down over/near OBX but primary hangs on longer than I want. I don't really know how good ICON thermals are but verbatim it's all snow in DC through Sunday night (~0.5" QPF has already fallen). The coastal basically zig zags a bit as it heads north from OBX to Lewes.
I like seeing the south transfer on the ICON.
