Not good, too close, too warm , winds off the Atlantic , etc. Surprised by this, as the EPS earlier was more offshore. As was the GFS Link to comment Share on other sites More sharing options...

Yea, it would still dump snow but there's going to be a mix period for sure. Looks like surface freezing presses back towards fdk/jyo Link to comment Share on other sites More sharing options...

osfan24 Posted March 12, 2017 Share Posted March 12, 2017 Ukie is a bit odd in that it's actually on the Delmarva but then seems to slide northeast from there. Link to comment Share on other sites More sharing options...

caviman2201 Posted March 12, 2017 Share Posted March 12, 2017 Is this just run to run variance on a complex, dynamic storm or are there new 'discoveries' the models keep making? I mean all the components are on-shore and being sampled at this point, so whats with the big run-to-run changes this late in the game? Link to comment Share on other sites More sharing options...

Slp moving 75 miles one way or the other is a very small change. It just seems big because of the affect of sensible wx. Link to comment Share on other sites More sharing options...

I know they are giving the American models extra data for this storm (dropsondes I think), not sure about the European ones. Link to comment Share on other sites More sharing options...
clskinsfan Posted March 12, 2017 Share Posted March 12, 2017 If the Ukie track verified I would most likely mix even out here. The GEM actually looks very similar to NAM as far as the heaviest banding goes. But like others have said we wont have a idea on that for another 18 hours or so. Regardless. All of the models except the Ukie have a very favorable track for all of us in this subforum. I am feeling very good about this storm now as opposed to being fringed all day yesterday.

PhineasC Posted March 12, 2017 Share Posted March 12, 2017 Not worried about the UKMET with the Euro being on the eastern end of the envelope. I don't trust the UKMET surface depictions too much. It could easily go wide right next run. Just a wobble. Link to comment Share on other sites More sharing options...

NinjaWarrior2 Posted March 12, 2017 Share Posted March 12, 2017 12z UKMET is mega wet, over 2" QPF, DC is ~34 for a lot of the storm, but 850s are warm too, it's probably a mega hit west/north of the Fall Line Link to comment Share on other sites More sharing options...

Bob is right, there probably is mix along the I-95 corridor at that time... but its not like the 850s are super warm at all as they are like 0/-1... we can still accumulate at 34 degrees Link to comment Share on other sites More sharing options...

WxUSAF Posted March 12, 2017 Share Posted March 12, 2017 A lot of times, the warm layer (if there is one) is around 800mb in these situations. 850-950mb might be cold again, with the surface around freezing, but it's a sleet sounding. If UKMET is over the Delmarva, got to imagine most places mix to sleet at least. But I wouldn't call all these differences "a lack of consensus". These are all within a very reasonable range of spread for 36-48 hours. We're talking like 50-75 miles here. But, that's the difference between all snow for the cities and snow-mix-snow.
