either this whole event is nada, or its a northern tier special that no one wants to talk about. 

I guess a combo of both. And apparently bobc and psu and a few others are stepping back for now because the looks are so not great, but I still think this will be a decent icy event for your area.

An advisory for that?  So basically schools are going to be delayed or canceled tomorrow for literally nothing

It's rush hour, so that's a standard issue advisory. It wouldn't take much for the roads to be an issue with lots of cars out and about.

Okay, maybe it is SOP for the NWS, I apologize. Still think that the official forecast in eastern areas of 0.0 inches of snow and .000000004 (exaggerating) inches of ice (which is essentially wet roads 99.9% of the time) is very Atlantaish.

I hope and pray I am totally wrong and this does end of warranting a WWA.

This is the official forecast. Its way over done for what is expected in eastern areas, which is basically nothing.

Did you guys look at the advisories?  LWX has issued four different advisories based on location.  Eastern areas expire at 10AM, another out west along the ridges at 11AM, then 1PM and 2PM for the normal areas east of the BR that don't usually warm in these events.

Yeah, western areas are a different story. But I think its crazy that kids literally pull school closures out of wet roads and we get advisories off this.

You need to go and read up on the advisory criteria.  Since it is happening at rush hour.... there is a whole different set of criteria.

This is such a beaten horse topic.  In this area, and in general. school systems are going to err on the side of caution.  Why do you let it bother you?  The volume in this area makes even a rainy rush hour a nightmare, so look at it as a win for those that have to go to work.

Both NAMs look to be swings and misses with the early "thump" near the cities (mostly confined to Western MD).  

      This really complicates the forecast a lot.    If that early round sets up further north, the kids in most of the area can get to school without problems.    And they'll be in school when the possible initial glazing occurs, and it will be above freezing by dismissal time.      But the NAMs can be dry with the onset of precip into a modestly dry air mass, so I'm not going to buy in fully unless the hi-res windows do the same.

      The schools will be in no-man's land for sure, but what's different here is that we'll probably hit 40 Tuesday and then only drop to a couple of degrees below freezing early Wednesday.  Saturday into Saturday night was considerably colder (and drier).   Thinking that the treated roads will be fine Wednesday, and glazing will be limited to trees and such (with temps as currently modeled).

I agree with everything. New NAM nest is holding off on precip again, so that certainly will help limit the icing potential if that comes to fruition. I think areas west of Rt 15 will be the ones back in the cross-hairs of any icing concerns. Our western folks out in Winchester to WV will see a more prolonged icing setup compared to east of Frederick. Ice just sucks to deal with during heavy commute times, and this one will be cutting it awfully close.

       I will say that I was banking on sun today and some heating, and I'm not as confident about that now.     While we still won't be starting from the cold state we did Sunday, the temperatures of untreated surfaces got cold last night and will be at risk of light icing tomorrow morning if we don't get some solar heating this afternoon.      But as you noted, questions about where the initial warm advection precip will set up complicates the forecast a LOT.

People are just mad that they don’t reap the benefits. Personally I really like the wimpy school districts.

My Wife works in a Fairfax school so some ask her what I think (which isn't much!).  Would the below be a potential freezing drizzle sounding?  I know it says 33 but I included a larger area where micro climates could dictate above freezing and below freezing temps.

Expected by whom?

You realize that the people at NWS aren't just looking at their favorite models on TT, right?  They have expertise in these matters that most of us here don't have.

Your interpretation of what is "expected" and what their interpretation is can be quite a bit different ........ because of the knowledge and skill level differences.

Those who have to go to work...that don't have school-aged kids, yes.

We've seen this song and dance before, and everytime, the usual suspects still manage to cash out on some ice. For me, if the surface winds do not generate what the model output is giving us for tomorrow, then it's going to be another "playing catch-up" with advisories as ice lingers longer than forecast. I'm not super keen on a carbon copy of Sunday, but this one could sneak up on a ton of people. Like you said, if we finish today colder than forecast due to lack of solar heating, it could be more interesting than one would hope as a forecaster.
