After a brief warmup this week the Jetstream drops south and steers the stubborn upper level low away... these features will combine to produce some snow showers in the northern Appalachian region and along the spine. As this system pulls away it will allow an area of canadian high pressure to settle in and take control of our weather. This will mean clear skies and relatively cool to cold nights here in east TN.
This will be the strongest shot of cold weather this season so it might feel quite cool on the skin and we could see the first frost advisories go out in the area. Looks like highs around 70 and lows around 40, give or take a few degrees. After this cold shot, look for more severe weather and even a stronger shot of cold air near the middle of October.
Stay warm
