Weather Summary:

We are tracking a break in warm and breezy conditions in the StormTrack 5 Weather Center.  We've hit the 70 degree mark in the Tri-Cities for the first time since October 28th of this year...that's nearly a month!  Some strong wind gusts have been recorded today as well, as a cold front slowly skirted by the region.

A storm system that moved up from the Deep South, responsible for our rain yesterday, continues to push north into the Great Lakes.  As it lifts north, it has slowly pushed the aforementioned cold front east of our area.  While cold air is on the way, the cool-down will not be instant.  It will take some time before we notice much colder air in the area.

As for tonight, winds will be on the decrease as temperatures drop into the mid to upper 30s.

While temperatures will fall back to below average on Tuesday, we'll see mostly to partly sunny skies as a weak high pressure system nudges into our neck of the woods.  Some changes are on the way, though, which could have an impact on travel plans this Thanksgiving...

StormTrack 5 meteorologists are tracking a low pressure system that is expected to hug the east coast Wednesday.  Before that, it will likely bring enough moisture into the already-cold higher elevations.  This could very well mean rain and snow showers late Tuesday night into the early parts of Wednesday.  As low pressure moves up the east coast, it will be close enough to bring back moisture into our area Wednesday and Wednesday night. The limiting force is that some areas may not be cold enough to support snowfall.  The east-facing slopes from the mountains of North Carolina up towards Smyth County are favored to receive moderate accumulation, while the Tri-Cities may see light accumulation, mainly on elevated surfaces.

At the moment, accumulation totals are not certain, as models need to come into further agreement.  Over the next 24 hours, however, we should start to get a better idea.  For now, you should be on the alert for slick spots on the roadways, mainly towards northern and eastern parts of our viewing area.

A greater concern appears to be for anyone traveling towards Baltimore/DC up towards Boston, as snowfall totals would likely be greater.  Still, more details need to be ironed out.  Once they are, we will continue to provide you with the latest on air, on mobile, and/or on the web.


A secondary wave of activity moves in from the west late, though will be much weaker, late Wednesday to early Thursday.  This could provide a few snow showers, again favoring the higher elevations but from west-facing slopes this time, as the main event drifts towards the northeast.  Temperatures will likely climb above freezing during the day on Thanksgiving, but will be noticeably cooler than average.

From Thursday to Sunday, we will see partly to mostly sunny with near average temperatures in sight. The first weekend of the Christmas shopping season should be OK.  Expect cool mornings and afternoon high temperatures ranging from the upper 40s to low 50s.

While there's a slight chance of some rain showers late on Saturday, forecast models are hinting at a more mild pattern taking shape.  That would certainly be a treat for us, as we have been subject to the second coolest November (to date) on record.

Highs will be in the low to mid 50s Tuesday, 40s Wednesday through Friday and middle 50s Saturday and Sunday. Lows will be in the mid to upper 30s tonight, low to mid 30s through Wednesday night with mid 20s Thursday night and Friday night and low to mid 30s Saturday night and Sunday night.
