Tennessee Valleys today, with a moist airmass ahead of the system
becoming moderately unstable. Thunderstorms will develop by late
morning along a surface trough associated with the upper-level
system. Supercell development will be likely around midday with a
few tornadoes possible. A transition to a squall line is expected to
take place during the afternoon. This squall line will move quickly
eastward across the southern and central Appalachians. Widespread
damaging winds are expected along the leading edge of the squall
line, with localized gusts above 65 knots possible.
