What is interesting is that the GGEM,-- use to always be the warmest is now the coldest for this event. It is not as dry as the GFS/NAM. I think south of 64 west of 15 is safe from a huge ice event from QPF alone-- if .5 to .75 falls, that's not your ice accrual number. 

What do you mean by this?  You think the QPF is too low for a major icing event?

Yes. if we get .6 < i'd be half falls as sleet and .3 falls as zr.  if .3 falls, .3 wont be the actual build up. Now, this is more along 460 area-- I know it's  a bit beefier up towards CHO . I think 81, Staunton to Winchester is ground zero for a significant event. 

 

I think the event will be notable along 460, but not major power outages, etc. 

 

Of course, watch the date trend away from what I think.

Gotcha.  We are really right on the edge of the dry slot here.  Given the resolution of the models, this could go either way.   But man, we are both really cold at the sfc for almost all the precip.  Looks like we stay in the 20s in CVA.

The 12z GFS is a serious icing threat for western MD, Central and western VA and Southern PA, eastern WV. Hour 90 has the 850 freezing line near Buffalo and the surface freezing line lagging all the way to the VA/NC border.

 

 

Thanks!!

GGEM is a HUGE ice storm I-95 and west

 

Still freezing rain 12z MON in DCA proper... changes to rain around 15z MON

RIC and EZF take a beating on the GGEM.  Freezing line like at Williamsburg at 96.  CAD on the necks of VA, don't see that often...well ever really.

Just doing my designated duty ;)

But yeah, GGEM has been banging the ice storm drum for quite a while its past few runs... been very steady

Now all we need it to do is spin the storm up to a cat 5 hurricane and it'll have covered all the GGEM bases.

As someone sitting on the right side of the RN/SN line, it's hard to not see the continuing trend over the past year of the line splitting Baltimore County and running down 295 and up and around DC. That's just based on looking at the Canadian, of course, but it holds course to how things have played out. From my side of the aisle, it bares watching.

As inconsequential as it seems, the couple 100 feet of extra elevation west of 95 makes a big difference with these setups. 

 

ETA:

 

this map shows it well. East of purple will almost always get less zr with CAD.
