... Windy conditions and a possibile outbreak of severe weather Wednesday and Wednesday night...

A strong low pressure system developing over the Southern Plains will move toward the Ohio and Tennessee valleys on Wednesday. Tightening pressure gradients around this system will increase the southerly winds over the area Wednesday. Windy conditions are expected area-wide. Southerly winds between 25 and 40 mph with gusts to 60 mph are anticipated across the higher elevations with 20 to 35 mph winds common over the great Tennessee Valley. The strong southerly winds will bring warm... moist and unstable air into the region in advance of an approaching cold front.

A line of thunderstorms will develop along the front... and move into the southern appalachian region by Wednesday afternoon and evening. This squall line will have the capability of producing widespread damaging winds. In addition... an isolated tornado or two will be possible.

Please listen to NOAA Weather Radio... or your favorite local television or radio station... for the latest forecasts and updates on this potentially dangerous situation.
