000 FXUS64 KMRX 281910 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 310 PM EDT SAT MAY 28 2016 .SHORT TERM...
-- Changed Discussion --
(tonight and tomorrow)... The issue of the short term will be how/if the tropical system off the SC coast will impact our area as it tracks NW. A shortwave trough will be crossing the area late tonight/early tomorrow...which may pick up some moisture from the tropical system and spread it across our eastern sections. With the best lift and moisture to our east...we should have some weak instability and a little upper divergence to help things along. Will have chance pops for areas east of Knoxville with slight chance pops west. Temps tomorrow will be dependent on how thick the high/midlevel clouds will be. Clouds should be thicker in northeast sections...and will have highs in the mid-upper 70s there with mid-upper 80s central and south. .LONG TERM...(Sunday night through Saturday)... Warm and humid conditions will continue with only slight chance to chance pops mainly eastern areas sunday evening through tuesday. A tropical depression along the South Carolina coast will move little during that time but eventually weaken and drift off the North Carolina coast by mid week. There will be a chance of showers and storms mainly along the eastern mountains and extreme northeast at least through monday as the tropical system brings moisture inland over the Carolina`s. Rain chances increase wednesday and continue through saturday as a weak cold front and upper trough moves into the Ohio valley then across the Tennessee valley thursday and friday. This system then stalls along or just east of the Appalachians saturday. Highs will stay in the mid 80s to lower 90s through wednesday then start cooling thursday through saturday down to the mid 70s to mid 80s with more cloud cover and increased rain chances. Only light rainfall amounts expected outside of thunderstorms through early thursday. More significant rains could fall thursday and friday with front across the forecast area.
