Updated HPC discussion. One paragraph to update what they wrote over night.

WE SEE NO COMPELLING REASON TO CHANGE CONTINUITY AND ADJUST PRELIM

HPC GUIDANCE SIGNIFICANTLY AFTER CONSIDERATION OF STILL VARIED 12Z

MODEL AND ENSEMBLE GUIDANCE WITH THE 12Z ECMWF NOW TRENDING CLOSER

TO THE COAST WHILE MOST OTHER 12Z GUIDANCE SLIPS MORE

OFFSHORE...OVERALL COMING CLOSER TOWARD OUR MORE CONSENSUS

FORECAST FOR A REASONBLY WELL ORGANIZED SYSTEM/TRACK.

what i like, even if we may miss the coastal or get grazed, we still get a 1-3 2-4 event with the ULL swinging through. You can see this on a lot of the gfs ens members

Yeah, you were the first to bring that up yesterday. It looks like a pretty good call at this point.

The 12z Euro ensemble still has a few cutters, which I guess isn't terribly surprising, since some members could still have a fast, sheared SW. Otherwise, the 12z operational ECM falls right in line with the ensemble spread at H5.

yea, there must be a good amount of members showing a primary going towards the lakes. The ens mean develops a low on the west side of the apps

Nam at 84, ton of moisture over Mississippi/Alabama..The ridge off the west coast is gonna help drop down the northern stream in later frames..Gonna have to wait for the DGEX.

seems to be a lot of confluence still over the NE. Last storm it got out of the way in time, but last year it hung around.

Will be interesting to see what the dgex thinks.

Well, 1060's calling tomorrow's 1-3" snowfall as a snowstorm. :rolleyes:

Hype and the Mid Atlantic with regards to snow go hand in hand.

Its only a snowstorm because accuweather says it is a snowstorm. Remember, any thing over an inch on the road is a storm event in philly. Did they brine the roads today? if not then this is a snowstorm.

And I know people think he loves to hype (though he didnt with tomorrow's storm) but JB is really bullish on next week's storm, particularly for the south over the weekend and then making the turn by Tuesday...he even mentioned blizzard of '83 though isn't going as far as to say we'll see that type of storm or those amounts

Looking at that map, it's gonna take an awful lot to get that northern stream s/w to phase in to the southern stream. Heights low across the EC don't show that doing a whole lot, unless it tries to pop it Miller B style with that northern stream feature.

heres the ggem ens mean, continues the same trend basically. ULL comes through and enhances precip and forms a low closer. On the hr 144 map you can see the big difference on the western side of the low between the isobars, meaning a good amount of spread.

I feel like thats a lot of precip for an ensemble 144 hours out. Either way, so far this aftn GGEM/EURO ensembles as well as the DGEX are very encouraging.
