Forecast Discussion

A dry front moved through Friday and colder air arrived Friday night. Canadian high pressure moves east across the Ohio Valley this weekend into the Atlantic Sunday night. We have a chilly Saturday and milder temperatures by Sunday afternoon. Radiational cooling (light winds and cold air sinking into valleys) makes valleys colder than mountaintops tonight.

Low pressure in the Southwest U. S. moves across the Ohio Valley Monday. It pushes a warm front across the region late Monday. Clouds increase Sunday and rain develops Sunday night. Monday has periods of rain ending late Monday night.

The next push of colder air is delayed until Wednesday making Tuesday an unseasonably pleasant day after the rain exits early. Temperatures will trend cooler Wednesday with increasing clouds.

Low pressure in the Western Gulf moves across Georgia early Thursday and into the Atlantic by late Thursday. Precipitation develops Wednesday night as colder air arrives. Precipitation may change to a wintry mix Thursday morning. Snow accumulations appear limited to higher elevations near the NC/TN boarder.

Skies clear Thursday evening. Friday looks mostly clear and seasonably chilly.
