Euro ensembles from 0z are pretty good compared to the op. About 5" on the means for dca for the Mon-wed period. Mslp track better as well. A good # of members have huge solutions but grain of salt with the flawed snow algorithm.

If the low does track West we can still do really well with front end stuff. It's looking to be a pretty wet storm overall. Could be a 2 parter.

according to JB the current track shown by EC and GFS , by the 500 MB pattern is correct, it will track almost over top of us,

There's still hope.   I think we need to face reality that this will likely be a front end dump type deal and hope for the best with that.

It could be a front end then mix to rain then lull the secondary lp with rain to snow covering a 48 hour period. lol

The evolution is very complicated. I'm baffled.

Wow gfs would out do the last ice storm. Verbatim surface maybe warm but thats probably a resolution issue, the setup is nuts.

 

???  I don't know, from what I'm seeing the GFS set-up still looks like crap, perhaps even worse than previous cycles.  It doesn't even have anything on the front-end, all the cold air is pretty well gone before anything arrives.  The 2-m temps are above freezing even up toward where you're at (Frederick?) before any appreciable precip even gets here.  At least through 144-h which is what I've seen up to so far.

:huh:

Its cold rain

1030hp funneling. Surface panels verbatim suck but I see the point being made.

The whole thing is super complicated. I'm not worrying much about op runs. They can change in a hurry (better or worse...not that it can get much worse than the 12z gfs) as the placement of the features are better resolved.

It flirts with freezing line up this way for a 24 hour period from 0z Mon. to 0z Tues. Basically temps hovering between 32-34 if taken literally.

Yeah, maybe out toward your way.  Admittedly, with the detail on the NCEP maps it's not easy to identify any "pockets" of colder air with those chart resolutions; you get the 0C line and the +10C line, interpolation is up in the air between that!

Starts at 1 am Monday...ice, then goes over to snow at around 8 am then continues until Tuesday around noon...lol  I love the GGEM.

 

EDIT..maybe ice hangs on until noonish  Monday.

 

Yeah you get 2" of sleet, plus 18" of snow on the GGEM through end of next week.

March 6-10 appears to me to be the best window of opportunity for a true winter storm for our region.

I'm not so sure early next week is simply rain for you guys. Let's see if we can trend more progressive with features, like we have all year, and get a colder solution here.

Time for the King to weigh in...anybody got the goods?

I'm only out to 126. Not a good start. We're on the losing side of the boundary to start. It's going to be a long drawn out evolution. We'll see.

ETA: I will say it's a bit more progressive down near the gulf coast. This is a net positive compared to last night.

somebody in NYC forum says it's ice for us at 144
