February 5-6 Storm Threat I


Baroclinic Zone

Recommended Posts

FWIW, the -nao does try to build back at the end of the ensemble runs. We may need it, as the PV pulls west and heights over the se try to build. I wouldn't be shocked if the pattern got ugly in the 11-15 day. However, we can hope that we are on the right side of the gradient like pattern, because the boundary will be nearby.

Wow, this 18z run of the NAM is over a 50% analog of Dec 9, 2005…. Really. That is a classic NJ Model bomb – I was thinking originally this was a juicy but weak Miller A, but it looks now like a higher latitude detonator. I suppose it makes sense with 586dm height lurking E of Florida and it would be about the only way it could snow here with that circumstance.

BOX AFD likes a track over the islands FWIW - has boston and eastern mass as the p-type battleground.

If the 18z NAM works out (and I believe it has just as much plausibility as any solution on the table at this point in time), dynamics would instruct an intense p-type gradient nestled snuggly into the somewhere between BOS-PVD and SE Mass...

Trust me.

Actually, very close to 00z.

Scott, the 18z NAM solution was kind of what I was talking about when after the Euro I mentioned we could see a closer tucked track but with rapidlyt falling heights, still see fairly cool ML temps. Kind of cool to see that play out on the NAM.

Are you saying this could be more than a 5-10" event??

I can't believe this storm is only 48-60 hours out either.. this Is awesome

It's a wetter snow... Looks like just over 1" of QPF at BOS ...perhaps knifing back along the Pike to about ORH ... at 10:1 ...maybe getting toward 12:1 toward the end of the deal.... 10" would not be impossible.

The differences between the NAM's thermal profile and the GFS thermal profile is pretty crazy here in CT...GFS would be more in the way of snow for at least the northern part of the state with perhaps some mixing...was nice though to see the 18z NAM trend slightly cooler with mid-level temps here...still suggestive of a mix though.

this has a Miller B feel to it with that intense vort max swinging down off the NJ coast and the reason for this bombing out...

that clown map is strange... would have expected more in northeast-mass from this:

Its quick moving and BL temps need to cool on the CP as the storm intensifies...in a sense it "uses" some of the QPF (via high VVs) to cool the column. But I wouldn't take clown maps seriously...there's a reason we call them clown maps.

This run is a clear 1-3C colder at 850 for ORH and points N - that's pretty significant with a 1.00" qpf wall in the area. It's also cooler for you guys, too. One thing this one won't have is issues between 850 and 700 mb - not that type of system with both mid lvl centers cutting underneath.
