Wintry 1/20 - 1/23 Winter Storm

It's a single operational run of a global model less than 30 hours out. It's like yesterday when the 18z NAM went out to sea and people were cancelling the event.

Forecasting is not using 1 model. It is looking at multiple models over a span of days and objectively seeking consistencies and formulating a guess. 1 Euro op run doesnt change the big picture of this event at all.
It doesn't. I don't think anyone is tossing the baby out with the Euro's bath water. But it's still a higher quality model than most others, and it doesn't do poorly close to events just because it's a global model. You'll find that most NWS offices use it up to the event taking place. I'm certainly not cancelling the event because of one run of the Euro. The point I was making is that it would have been better if it would have trended in the same direction with the rest of the models with its depiction of precipitation. It may mean nothing in the end, but that would have been better.
 
I don't understand the pessimism for some here. First off, this is an Eastern NC storm and IF you are lucky enough to see something to the West, that's a win.

h500 looks better across virtually all modeling. The precipitation field is expanding overall across all guidance.. forcing looks better, 700mb, etc. This is 24+ or so hours away on the back end for the Western areas (after 7am tomorrow) if you were to even get it...

Surface maps aren't gospel and me thinks the radar and nowcasts will show that .......
 
The HRRR going a little ham with this arctic front.....

I mean if the HRRR has a wheelhouse this is it, it has not wavered on the anafront precip and actually is doubling down. Seeing those early mPING reports are very promising as well

Freezing rain zone slightly expanded in southern area
Snow accums look about the same
Winter impacts still heaviest in NC, likely due to lower ground temps there.

I’ll fire up the 18z run as soon as that data is available.

39/38 here with rain, HRRR had us initializing at 40 at 2pm falling to 39 by 3pm (so on track). Most models along with local mets/NWS calling for around an inch (maybe higher) with the front tonight with 4”-6” for the second event Friday. Maybe a little too high, but we’ll see. Biggest possibility for major snowfall since Jan 2018 here.
 
Surface just isn't reflective for some reason.
Yeah it’s very confusing to say the least… you look at the H5 and it’s following all other trends of the day and continues to improve, but it and the Euro their just isn’t the surface reflection to match that. I’d hate to have to try and put a forecast package together with that
 
Whatever’s happening tonight just reeks of something models whiff on, frontogenesis magic

The surface map infatuation is getting to me here.... I literally just loaded bufkit's overview (the actual crappy Windows 95 type program) for my back yard way in CAE and even on the NAM the upper levels aren't far off.. and that's the "drier" NAM way back here..
