January 4th Mothrazilla: Final Call & Observations

Yea 3-6 hyde, not that far from better or for worse too!!!

Lonnie just said track still up in the air

The precip is getting pretty far west into Virginia, much more than the models had, even the NAM

RB whats your thought about all the dry air in place in the HV? Is that going to be an issue for us?

Jeez. I guess we have to be careful what we wish for. Too far of a track west and LI will sleet lol

All NYC schools are closed tomorrow. Announced a few seconds ago

Hey hey hey, when I said I wanted a truck load of snow this is not what I meant!!!!

Dew points are definitely low, so it's gonna take a fair amount of time to saturate the column. That said, with such a backing flow regime coming off the Atlantic the mid- and lower-levels should steadily saturate as it approaches. The wind direction right now is important; note how it's from the east-south quadrant, and not from the northeast-west third. That's good because that means we aren't having the really cold, dry air drain into our region from New England and Canada.....yet. Not until the low begins getting closer to our latitude.

There's been some chatter over at the other board why the GFS suddenly makes a ENE jog when the low approaches our latitude. With an already negative trough, that would argue for a more northerly trek closer to the coast. On another note, Lee Goldberg mentioned earlier that the snow shield is more west then what the models show. 0z runs will be telling tonight!

yes Hyde that dry air plus a arctic front Albany talked about could be a problem  for us, but I still like right now 3-6 for us.

I have to say, after reading Ray's post I took a look at the satellite/radar and it sure does look like the low center is tracking inside of Hatteras.

Last night I noted how close the low center was to Hatteras on a couple of models, but it was still offshore -- not west of Hatteras.  It's interesting that everything real-time today, radar, satellite, pressure centers seems slightly west of where it was on the models.

Frank, looking at that radar we could have precipitation over us by about 10 pm, no? That's about 5-6 hours early. lol

So wait, if the low tracks west of Hatteras, does that mean I am likely to jackpot?

No big deal, even the NAM is only about 300 miles too far southeast with its progged jet for 00z. Meh, that won't change the forecast at all ahaha

Wow a call on NYC schools before morning wow.

In my write up I said 1 to 3 am from south to north. May start as virga

lol. so true. and I was being kind to the models when I said "slightly" west of the models

Agree!! The closing off of H5 alone argues against that, but even if it does, the precip shield should not be negatively impacted. Throw in what our current jet looks like and I'm just slightly inclined to say that jump doesn't make sense, and the precip should be healthier than modeled further to the west.

*IF* it does, you might not technically jackpot, but you'd likely more than double your 2-4" forecast from the NWS lol

Yeah, it definitely would still be on target with what you said in your write-up. I was thinking more of where the models and other forecasters had this thing projected earlier today. It seems accelerated from those projections.

Hmmmmmmm

Hmmmm good or hmmmm bad?
