The skies have finally opened up and light rain began falling Saturday afternoon just before dark. Upon the mountain, NCL Weather Watcher, John Taylor sent us this note about the weather up there:

You can check out all of the various Winter Storm / Advisories and Ice Storm Warnings by checking out the graphic above and clicking on the associated hyperlinks that are highlighted. As just mentioned, much of the day higher elevations have been seeing freezing rain and sleet on the mountains. The temperature at NCL-Wintergreen Nature Foundation hovered around the 20° mark for most of the day, while valley temps hung around the mid 30’s. Obviously on the mountains they are the most prone to more serious icing because of the temperatures. You can see the estimated ice & snowfall amounts in the lower graphics for the next several hours. As I mentioned in earlier updates, this unfortunately appears to be more of an icing event vs a snow event. There’s going to be a critical period from roughly 6 PM Saturday until 6AM Sunday where we could pick up some ice.

There’s a period in there where valley temperatures may briefly dip to or slightly below freezing, but then rebound after midnight. Dewpoints in the valley are in the mid 20’s right now, so we could drop temperature wise to around 30° or so as the air moistens up. (Air temperatures can never drop below the dewpoint, so that is a good indicator as to how low the temps can drop – when dewpoint and temps are the same you have 100% humidity or saturation = rain or some kind of precip) That would allow for a few hours of icing as the rain moves in. On the mountains, you are already getting freezing rain and are essentially under a Winter Storm Warning until 1PM Sunday. The actual line ends at Augusta and the converts to a Winter Weather Advisory in Nelson, but since the Blue Ridge Parkway, Wintergreen, and Montebello all are on that BRP ridge, that skews things a bit.

Again, the bottom line on it all. Look for rain to begin changing to freezing rain in the valley of Nelson. The mountains stand to have the greatest impact from this event. Little snow is going to fall there. As of 5:00 PM as this forecast was being prepared, our NCL-Nelson County Life Weathernet station is indicating 33.6°. About a 1 degree drop in the past hour. We should hit the freezing mark in the next few hours and hover there until after midnight. That’s when temps should begin rising again and inch above the freezing mark. Look for this to last much longer on the mountains since they are much much colder there.

This will linger into the early morning daylight hours Sunday, then look for sunny conditions to return by afternoon. It will be very windy with speeds gusting to 50+ MPH on the mountains and around 40 MPH at times in the valley.

Should conditions worsen overnight I will be updating here with any bulletins, road conditions, and the like.

    Thanks for the wonderful local forecasts. I enjoy the Vince Garaldi Charlie Brown Xmas music, too. Your house looks SO NICE decorated for the holidays. Enjoyed your card with the doggy pic, and yes, we just don’t get together when the Farmer’s Market is closed. Happy Holidays.

    6:04 PM On Wintergreen:
    Current conditions at 3300′, 26 degrees (slightly up), and drizzling. Outside wooden deck is still treacherous but a recent sleet has given it some texture. Gravel driveway is a sheet of ice but the roads, which have had 3 visits from WG trucks, in front of the house seem no worse than wet.
