Very tight gradient on the 850 mb temps, just 10-50 miles north of the 0 degree line is the -2 degree line.

Yeah, and what could become nasty is if the 850 mb temperature trended warmer and the surface temperatures remained the same. That would be a nasty ice storm for us, because it wouldn't take much to bring the 850 mb temperatures warmer than ideal on the 18z DGEX with this storm.

No one posted the 18z DGEX in the Banter Thread? It shows a nice storm for the area in the 15th-17th timeframe. It looks to come in two parts, with the second one being colder than the first part.

850s and Surface Temperatures are cold enough for the northern half of NJ, but the thicknesses are at 546, which is marginal, at best for snow. Could this be IP or ZR?

The second wave is colder at the 1000-500 mb thicknesses, and would likely support snow.

And the DGEX once again regains its title as the king of fantasy storms... When the 12z or 0z GFS runs show a snowstorm, the DGEX in some cases seems to take them and exaggerate it even more.

Then the GFS comes back with a storm that appears to imitate in appearance the 12/26/10 blizzard on the models at the time that it was expected to go OTS, except for that the entire set up is different:

Right. No use stressing about it though, we're still almost a week away. Still, Accuweather has practically guaranteed no major snowstorms until the last week of January, and it would be nice to prove them wrong.

To say that there will be NO major snows like Accuweather said is definitely a bit irrational, because as we have seen with weather, anything is possible.

The GFS was VERY close to producing something big here, and with an improving pattern and a cold air mass already in place, this storm definitely needs to be watched.

The 00z runs should be REALLY interesting for this storm.

If they even show the same solution. Each of the last 3 runs showed something noticeably different, a clear sign that the GFS is still having issues handling the set up in this time frame, and will likely show a different solution again with its 0z run. The only thing we can take from this at this time is that a storm is possible between Sunday and Tuesday.

Lol. Don't forget 12z tomorrow!

Like every storm in the past that the GFS has out to sea at one point or another?

Lighter band developing to the NW, will it continue to expand or not? That is our hope.

The best forcing/vv's look to be headed just offshore in the next couple hours, so this one appears to be over for flake chances. Radar indicates some echos about 5-6 miles east of me.

Even DCA managed to scratch out 6/10ths of an inch of snow this afternoon...which is a solid 6/10ths of an inch more than I've measured since March...

Given they've penciled in nearly an inch, that has to be great news for our prospects in this pattern, given we've been averaging about 3-4X DCA snowfall the past 10 years. :lol:
