Forecast Discussion

High pressure has settled along the Gulf Coast and slowly builds across the Southeast through the weekend. This will result in abundant sunshine through the weekend with a moderating trend in temperatures. Our next frontal system develops over the Plains on Sunday.

The next low system reaches the Midwest by Monday with a cold front extending through the Lower Mississippi Valley. The front crosses the Tennessee Valley late Monday bringing increased clouds throughout western Virginia. Showers develop late Monday afternoon and linger through the overnight hours. Some higher elevation spots will have a mix of rain and snow overnight with no accumulation expected for now. Clouds diminish Tuesday as high pressure builds in. Temperatures will be cooler than the weekend but at seasonal values.
