    The Triad is now transitioning to freezing rain. 31 in W-S, 32 in GSO.

    The morning 6z NAM products and 12z HRRR is making this more of an I-40 and north event. The 12z HRRR will make most jump ship if you are south of I-40.

    It’s currently 28/15 south of Greensboro in Northern Randolph County. High clouds just beginning to move in.

    I think they actually ticked up along and north of I-85. I wouldn't be surprised to see RAH put Davidson, Forsyth and Guilford in the Winter Storm Watch.

    I should have said in the Western Piedmont of NC... my bad.

    The 12z RGEM is absolutely ridiculous on the ice. Major Ice Storm in the CAD favored areas.

    The 12z NAM 3Km is more believable and more inline with local forecasts.

    12z NAM Total Accumulated Freezing rain. I'm not aware of any WFO's or media outlooks mentioning the possibility of an Ice Storm. Just Social Media chatter at this point. Let's see what the other 12z data shows. I know the NAM does well with temp profiles, but I'm not sure about precip rates.

    00z NAM freezing rain totals through 7am Sunday. I-40 Corridor looks to be the zone for best icing right now.

    Yea the Icon doesn't output IP,ZR. If you look at the surface temp maps, favored CAD areas are below freezing during the event. ICON also has the secondary wave of low pressure on Monday.

    Concerned as in it looks awfully north?

    Pivotal now has skew-T plots for the CMC. Classic Ice Storm over Central NC at hour 138. Just one of many outcomes still on the table. http://www.pivotalweather.com/model.php?m=gdps&p=prateptype&rh=2019010712&fh=138&r=conus&dpdt=&mc=
