Weather Summary:

StormTrack 5 meteorologists are tracking a cold front that will slide into the region today. This front will move into the Tri-Cities area during the warmest part of the day, so scattered showers and thunderstorms are likely this afternoon and evening. The best chance of rain will be mid-afternoon through the early evening. A few storms could produce frequent lightning, brief downpours, small hail, and gusty winds in spots. I wouldn't cancel any outdoor plans, but keep an eye to the sky and the radar on WCYB.com or the StormTrack 5 mobile app. Have the rain gear handy. We will alert you to any severe thunderstorms, should they develop.

Showers will end by midnight most areas. Skies will become partly cloudy tonight, which will lead to areas of dense fog. Monday will be much cooler with highs only in the mid 60s to near 70! Morning clouds and fog will give way to sunshine in the afternoon.

A large area of high pressure will settle in and become the main weather feature for this week. Skies will be partly to mostly sunny. Humidity levels will be low with cool nights and warm days... perfect weather to kick start the fall color! A few more clouds are expected by late week as a storm system develops to our southeast. A few showers can't be ruled out in the mountains by Thursday.

Highs will be in the upper 70s to lower 80s today. Cooler Monday with highs only near 70. Mid to upper 70s the rest of the week. Lows will be in the lower to middle 50s tonight. Chilly nights are ahead next week with lows in the 40s Monday and Tuesday nights and in the lower 50s Wednesday through Friday nights.

This is the last weekend of summer. Autumn will officially arrive at 10:29 Monday evening. The cooler air will be arriving right on schedule!

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