Is it drier than it should be for a storm so strong or is it because fast moving?

No your right it was a weird run and it did some weird things with the precip.  Should have been wetter given the development. Plus it allows the low to escape east vs being pulled north like the gfs and U.K. Not sure I buy that given the trough alignment. It splits into two h5 lows almost to do that.

There are some suspect details but the important thing is no major hiccups from any of the 0z guidance. The train is still on cruise control.

Ignore the other globals. It's amazing that a server farm in Reading, England understand our climo better than American entities. 

From what I'm reading the totals are not that far off from the GFS and CMC. Not sure how much snow the UKMET put down. I've seen the Euro come in too dry at times.

As some on these boards may know I am not a big proponent of censorship and of Mods wack-a-moleing posts left and right. I always believed that part of the enjoyment was what when on between the analysis from some of the more knowledgeable posters. But this only works if there is a little self control from all the posters. Without that we have a board that for the most part becomes near unreadable for those of us that step away for a few hours. After spending close to 45 minutes weeding through 12 pages just to get a page or two of worthwhile information I think maybe we all need to start filtering our posts somewhat as to usefulness to the conversation. Not saying shut down all banter, maps, etc... Just tone it down a little.

Fret not..once we get to the storm thread, it'll be tight and clean.

Oh NO!  It MAY be coming for me!

The latest from LWX:


.LONG TERM /MONDAY THROUGH THURSDAY/...
Winter weather continues to look more probable early next week
as coastal low rapidly strengthens while moving N/NE along the
eastern seaboard. While still too early for specifics...nearly
all long- term guidance now suggests possibility for at least
some accumulating snowfall over much of the area (which is
notable if only for the fact that we have seen a dearth of snow
this winter east of the Allegheny Front).

Ultimately...impacts will largely be dependent on spatiotemporal
evolution of coastal low and if/where phasing of the upper stream
occurs. This should continue to become clearer over the next
several guidance cycles as intra-/inter-model consistency
hopefully becomes established.

Current timing would favor greater potential for
accumulation...as primary accumulation period occurs Late
Monday through early Tuesday morning (i.e., a period devoid of
much filtered March sun). Furthermore, moisture-laden airmass
juxtaposed with anamolous easterly flow in low-/mid-levels
suggests winter storm warning criteria is certainly possible
across portions of the area. However...depending on track of
low...transition zone could set up...which would limit snowfall
accumulations where mixed precipitation occurs.

Finally...keep in mind that ensembles of both the ECMWF and GFS
still exhibit tremendous spread in QPF...and thus snowfall totals.
Thus...it is unwise to put too much weight on any one solution as
uncertainty remains large. Main takeaway is that this system has the
potential to produce significant impacts across the area...but
confidence in any one solution remains large.

Wraparound precipitation will remain possible through Tuesday as
surface low moves away from the area. High pressure will then
gradually build into the area through Thursday. Sensible weather
from midweek on will be largely dependent on early week system and
quantity of any snowfall.
