A cold front has stalled out in the southern Appalachians region. As this front continues to meander around us, a few weather disturbances will ride along it. The moisture and lift with these systems will be enough to produce some on and off, light to moderate rain showers.
This front finally picks up steam late Tuesday and early Wednesday, as another system kicks it east. With this second system, we'll see another round of rain before a rush of cooler air. Some of the showers we see, especially late Tuesday and early Wednesday, may be heavy. That would likely be the case near and east of I-81.
With the rain over the next few days, we may face some issues on the roadways, in which ponding can lead to hydroplaning. Runoff may also become an issue. While flash flooding isn't likely, areas that see more rain may see some stream/creek/river flooding develop through Wednesday. That's why a Flood Watch is in effect for east Tennessee and southwest Virginia through Wednesday morning. Be alert for rising water in flood prone areas. One area to watch is the Clinch River near Speers Ferry, which is forecast to get near flood stage by Wednesday. Rain totals may amount anywhere from 1-3" (locally more) between now and Wednesday afternoon.
Afterwards, the weather looks cooler and mostly rain-free from Thursday through Sunday. High and low temperatures will return to more seasonable levels during that time. A stray shower and more clouds come into the forecast on Monday with warmer temperatures as well.
Temperature Outlook: Highs in the upper 50s/lower 60s Tuesday, upper 40s to middle 50s Wednesday through Sunday, and mid/upper 50s on Monday. Lows in the upper 40s/lower 50s tonight, 30s Wednesday night, 20s Thursday through Saturday night, and near freezing Sunday night.
Our average high is 52°, low 31°.
