Wed PM update...

I am focusing on our system tonight and tomorrow. The picture for the weekend potential system will get clearer once this current system passes and the responsible disturbance gets on the RAOB network.


Winter Weather Advisories are our for GSO, CLT, the Triad, and Triangle. Winter Storm Warnings have been hoisted up in VA down into Surry county and the NW NC mountains.

The latest NAM did shift the axis of heaviest precip south 30-50 miles. There have not been any huge changes on the WRF or the regional Canadian.

Here are my thoughts as of this afternoon.

A quick-hitting shot of sleet and snow will develop into much of the Upstate and Piedmont after midnight tonight. Some accumulations are possible, but south of I-40, it will probably be pretty minor. A dusting....maybe an inch in a few spots in the southern Piedmont. Maybe one or two spots with a little more, especially the farther north you go.

In the southern Piedmont, any remaining precip should transition to sleet and rain or freezing rain as the morning unfolds, and a glazing is possible in some areas.

For the CLT region, this is not a huge winter storm. However, I still think the potential is there for some road issues to develop. Ground and road conditions are quite cold, and it only takes a tiny amount of mixed precip to cause sizable road issues....just ask the folks in Mississippi and Alabama today.

Farther north, from roughly I-40 up to near the VA border....I expect front-end snow to transition to some freezing rain in time tomorrow. By the morning rush, there could very well be an inch or two of snow and sleet on the ground in many Triad locations. A glazing is then possible on top of that. I fully anticipate the possibility of some travel issues by the morning commute in many Triad locations.

Near the VA border and on up into VA, this will likely be where the meat of the storm rolls through. In that area, I would not be at all surprised to hear of some localized 4" or even 5" reports.

That's it for now. I will be in the wx office dark and early in the AM. Get up a little early and check the weather, road, and closure situations in the morning.
