... Unseasonably cold conditions tonight with near record low
High pressure will build across the eastern United States... bringing
unseasonably cold air into the southern appalachian region. Mostly
clear skies and light winds will allow temperatures to fall fifteen
to twenty degrees below normal tonight. In fact... low temperatures
will approach or exceed record values for the 25th. With temperatures
falling into the 30s in the valleys of southwest Virginia and
northeast Tennessee... patchy frost may develop in these areas
towards sunrise on Saturday morning. Sheltered valleys will be the
most susceptible to frost formation late tonight.
