625 FXUS64 KMRX 230217 AAA AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 917 PM EST Wed Feb 22 2017 .DISCUSSION...
-- Changed Discussion --
Fog is beginning to develop in some areas as the midlevel cloud deck clears out. Temperatures have already reached the dewpoint in some spots, so the mention of fog in the forecast is on track. The question is how widespread will dense fog become. Besides TRI, the latest LAMP guidance is not showing less than a mile visibility at most sites. With some uncertainty about coverage, will issue a SPS for the entire area. A few small tweaks will be needed to temperatures, but otherwise the forecast looks on track.
