A FEW STORMS COULD BE STRONG TO LOCALLY SEVERE
RAIN CHANCES WILL LOWER NEXT WEEK

Saturday: Partly sunny. Scattered showers and thunderstorms(60%). Highs 85-91. Southwest wind 5-15 mph.

Sunday: Partly sunny with a 30% chance of showers and thunderstorms. Highs 82-87. Southeast wind 5-10 mph.
We are tracking more scattered showers and storms in the StormTrack 5 Weather Center. A slow-moving frontal system remains north of the News 5 WCYB viewing area. Warm and moist air has been flowing into the southern Appalachians. This will help create more scattered showers and thunderstorms the next several days.
Upper level flow from the northwest will steer any storms that do develop from the northwest to the southeast, like the two days past. This upper level pattern also makes storm development tough to predict, as we rely on the instability of the atmosphere, lift along the front, and pulses in the upper levels to carry the activity downstream into our region. Still, it appears as though (like clockwork) that the best chance of rain today appears to be late afternoon through the evening.
A few storms could be strong to locally severe. The main dangers from any storm will be frequent lightning, gusty winds, heavy rain and small hail. Keep an eye to the sky this afternoon and evening.
Outside of any rain, it will be hot and humid! "Feels like" temperatures will climb into the lower 90s. Don't forget to drink plenty of water!
StormTrack 5 meteorologists are tracking a ridge of high pressure that will strengthen just to the southwest of the Tri-Cities. As mentioned before, this will allow for a progression of weather disturbances to track from northwest to southeast across the Ohio Valley and into the southern Appalachians.
Tomorrow, the slow-moving front that we mentioned before pushes southwest in a "backdoor" fashion. This could enhance our shower and thunderstorm activity early on in the afternoon, with scattered showers and thunderstorms possible late.
Scattered showers and thunderstorms will be around for Race Weekend and the Appalachian Fair. Most of the time it will be dry, but when it rains it could be heavy.
A ridge of high pressure will extend eastward early next week allowing for lower rain chances to enter the forecast. Lower humidity is expected by Tuesday as well as the pattern changes!
