Weather Summary:

StormTrack 5 meteorologists are tracking a potent storm system making its way from the central United States towards parts of the deep south. The dynamics of this system play into a severe weather threat across portions of the Deep South, up the east coast towards North Carolina.

While the chance of thunderstorms in the Tri-Cities area is low, there are other impacts we need to be alert to. As low pressure area lifts northward toward the Great Lakes, it will slowly push a warm front our way.  Moisture and lift associated with this will be enough to provide some rain throughout the day with rain chances highest around midday through the evening.

Strong southeast winds are likely to develop and last through much of the night. The National Weather Service has issued a High Wind Warning for this afternoon through Monday morning for the mountains and foothills of east Tennessee and southwest Virginia. This could result in some downed trees, damage to power lines, and hazardous driving conditions. This is again one of those events that is highly localized, not widespread. 

The normally wind-prone locations including Camp Creek and Roan Mountain, TN could see wind gusts over 60 mph. Breezy conditions are possible in the Tri-Cities today and likely Monday, but the really high wind gusts will be localized to the mountains and adjacent foothills.

Meanwhile, a Wind Advisory is in effect for Smyth and Tazewell Counties in Southwest Virginia until 1 AM Monday.

Rain is likely today, especially around lunchtime and into the evening. Rainfall could be heavy in spots. It appears most of the area will receive around 0.25" to 0.50" of rain with locally heavier amounts possible.

Rain chances decrease overnight. Temperatures will be very mild tonight as a strong southerly flow continues ahead of a cold front. The front will slide through Monday bringing some scattered showers with it (right now rain chances look highest from mid-morning through mid-afternoon Monday).

Monday looks breezy and almost warm after such a long stretch of cold weather.  High temperatures are expected to be 5-10 degrees above the average.  A much cooler airmass arrives Tuesday, with Wednesday even a few degrees cooler.

We will be tracking an area of low pressure system riding up the east coast mid-week. It appears that some rain and/or snow showers will be possible Wednesday, especially east of the Tri-Cities area.  Our rain/snow chances depend on where this low pressure decides to move.  The further west it is, the more likely we'll some form of precipitation on Wednesday.  The further east, the less likely we are to see any rain or snow.

Snow showers are possible through Wednesday night and into early parts of Thanksgiving.  At the current time, forecast confidence is low on any details, so be sure to check back for updates on-air, on the web/social media, or on our StormTrack 5 mobile app.

Some (probably light) snowfall could impact holiday travel plans near and east of the Tri-Cities area on Wednesday and Thursday morning. Right now temperatures are forecast to climb above freezing during the day and fall below freezing at night.

Thanksgiving and the days to follow will feature below average temperatures with partly to mostly sunny skies.  Overnight lows will be in the mid 20s once again.

Highs will be in the mid to upper 50s today, lower to middle 60s Monday, and in the 40s Tuesday through Saturday.  Mild lows in the mid to upper 40s tonight with lower to mid 30s Monday and Tuesday nights and 20s Wednesday through Friday night.

You can get the latest forecast, radar, and severe weather alerts on News 5, WCYB.com, and on the StormTrack 5 weather app.

Our normal high is 56°, low 33°.
