Sunday: Partly sunny skies. Highs 43-49. Light wind.
Sunday Night: Mostly cloudy skies. Chance of showers, mainly after midnight. Lows 32-37. East wind 5 mph or less.

Patchy drizzle or a few mountain flurries are possible this evening. Some clearing is expected tonight with areas of dense fog possible. Temperatures will drop below freezing tonight in some areas (especially higher elevations) so be alert for possible icy patches on the roads, bridges, and overpasses.
Partly to mostly cloudy skies through Sunday. High pressure to our northeast will keep us mostly dry. Winter officially arrives on Sunday evening at 6:03.
A storm system will develop to our southeast and move north Sunday night into Monday. There's a chance of light rain in the region, especially east of the Tri-Cities Sunday night and Monday morning (a wintry mix is possible near the Blue Ridge).
We are tracking another storm system for next week. Ahead of it, winds will begin to surge out of the south. Expect breezy conditions from Tuesday night through parts of Thursday, as this system will be in our vicinity. Winds out of the south on Tuesday means warmer air is on the way, where high temperatures (depending on timing of rain) could make their way towards the 60 degree mark. As the storm system looms closer, rain chances go up and a thundershower or two may also be possible. Cold air remains well off to the west, and seems to be further delayed with each forecast model run.
Christmas Eve will be mostly cloudy with rain showers likely. With the latest forecast models, we are seeing a trend that brings in colder air late Wednesday evening into early Thursday. Rain showers will change to snow showers Wednesday evening or night. Right now any snowfall accumulations look light, but check back for updates. Remaining moisture may be the limiting factor in how much snow we actually see with this system.
Traveling may be tricky for Santa Christmas Eve as breezy conditions really pick up, with some lingering snow showers or flurries into Christmas morning. After those taper off, we'll see clearing skies. The wind will die down as the day progresses. Lows Christmas morning will be near 30 and highs will be near 40. Temperatures will rebound Friday into the lower 50s with partly cloudy skies.
Highs will be in the upper 40s Sunday, near 50 Monday, near 60 Tuesday, near 50 Wednesday and in the 40s Thursday. Back in the 50s on Friday. What a roller coaster ride! Lows around 28 to 38 the next seven days.
