Clear, Cold, Refreeze Overnight

Skies are clear tonight and temperatures bottom out pretty good by tomorrow morning. If it weren't for a little wind tonight, temps would be even colder. Any melting that occurred today will certainty refreeze tonight so be wary icy and slick roads tonight. High pressure passing to our south the next couple of days promotes quiet weather. However, another big southeastern storm system gets into gear Friday. Rain arrives late Thursday night, picks up the pace Friday, and light rain lingers Saturday.

Forecast Discussion

The weather map remains pretty quiet for another day giving us continued opportunities to completely dig out. High pressure is at the helm through Thursday. Overnight ingredients are good, but not pristine, for radiational cooling conditions. A northwest wind will once again keep temps from bottoming out except for sheltered valley locations. Not complaining :-).

A vigorous storm systems ejects from Oklahoma/Texas Thursday and heads in our direction. Clouds thicken Thursday with rain arriving late Thursday night. We'll have to keep a watch on the potential for a brief spell of freezing rain in the predawn hours Friday. Otherwise it's all rain and a good one at that Friday. Light rain hangs around Saturday and the storm total rainfall will be 1"-2" making a mess with the combination of melting snow. Stream flooding could be a problem.

Drying commences Sunday afternoon. High pressure builds from the Midwest early next week and temperatures hang around the seasonal category.

For a historical perspective... after searching through all the December snow data for Boone this last event is now the biggest December snow on record. The 18.5" of snow over 2.5 days, beat out Dec 26-27, 1969 when we had 18".
