StormTrack 5 meteorologists are tracking a strong storm system developing over the central United States. This is a dynamic system with severe thunderstorms possible for the Gulf Coast states through the Carolinas Sunday.
While the chance of thunderstorms in the Tri-Cities area is low, there are other impacts we need to be alert to. As a 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 Sunday with rain chances highest around midday through the evening.
Strong southeast winds near the mountains and foothills will likely develop overnight or early Sunday and last through much of Sunday night. The National Weather Service has issued a High Wind Watch for Sunday 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.
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 Sunday and likely Monday, but the really high wind gusts will be localized to the mountains and adjacent foothills.
Rain is likely Sunday, 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 late Sunday evening. Temperatures will be very mild Sunday night as a 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. Much cooler air arrives Tuesday and Wednesday looks even 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. Snow showers are possible through Wednesday night and into part 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.
Highs will be in the mid to upper 50s Sunday, lower to middle 60s Monday, and in the 40s Tuesday through Friday. Lows will be in the mid 30s tonight. Mild lows in the mid to upper 40s Sunday night with lower to mid 30s Monday and Tuesday nights and 20s Wednesday and Thursday nights.

Our normal high is 56°, low 33°.
