.DISCUSSION...
-- Changed Discussion --Approaching upper low and associated surface front with a
reinforcing shot of cold air is approaching our NW counties this
evening. Band of showery precipitation with an isolated
thunderstorm or two lags behind the surface front in area of PVA
associated with vorticity lobe rotating through the base of the
middle level low. Short range models agree that much of the
precipitation currently over Eastern KY and Middle TN will weaken
and dissipate as it moves further east into our area around
midnight. Adjusted temperatures and sky to reflect current
observations and frontal timing. Otherwise forecast looks
reasonable given latest radar and short range guidance.-- End Changed Discussion --
