NAVGEM and JMA ccb DC north.
Really odd that most of the globals and the 2 Canadian meso's get some CCB down here...while all the NCEP run meso models, HRRR/NAMs/ARW/NMM all are not even close and stall the low much further north.
yea that stall and wrapping banding across northern MD for days is great and all...and sometimes it doesn't take much QPF to rack up totals in those bands...fluff...but its risky relying on that...some of that is still 60 hours away and if you take out that last band that wraps through MD really doesn't get a whole lot from the coastal.
A lot of guidance is trending towards pinwheeling the low around on Tuesday and swinging snow back through the area north of DC. Have to see if that is real...and if we can get it to happen maybe a bit further south.
GFS has trended southwest with the coastal low capture/stall the last several runs...but without having much impact on the CCB frustratingly lol. But again its super close for DC...this run the capture and tuck happens right at OC which is exactly the latitude that puts DC on the edge for getting into the CCB.
I know you’re kidding but that wouldn’t help. That’s the last thing we need. That would squash the WAA wave and still wouldn’t help with the coastal. Might even make it phase and amplify slower and end up OTS for everyone. Our problems lie in the typical miller b transfer problems.
Ehh rgem isn’t the NAM but it shifted the ccb northeast quite a bit. Still decent DC northeast but not close to the last few and the trend is troubling.
Right or wrong (probably wrong) the NAM is chasing the convection and taking the secondary way too far OTS. It’s improving slightly each run with that but not enough. You can see the slp ride up the line of convection that fires out over the gulf steam vs tucking in along the coastal front baroclinic zone.
@Weather Will is slacking
cue yeoman with “looks like climo”.
6” one isn’t too shabby either
keep in mine ensemble members are low resolution and 10-1 so they are going to underestimate snow totals (when you actually do get it lol) if it’s a cold storm or you get under the ccb
That could just be due to the double barrel or strung out low configuration you get as it’s captured and loops. Where exactly the lowest pressure is any any one time isn’t that important.
It’s really consistent. It seems to be where the moisture transport from the secondary is meeting up with the inverted trough from the dying primary and enhanced by instability from convergent winds ahead of the h5 and old h7 lows. The gfs has it too just further northeast and it’s not as sharp since gfs sucky resolution and all. On top of its sucky everything else.
