000 FXUS64 KMRX 211934 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 334 PM EDT Thu Sep 21 2017 .SHORT TERM (Today into tomorrow)...
-- Changed Discussion --
Isolated showers and thunderstorms are forming (mostly along the higher terrain) this afternoon. We should continue to see these storms through the afternoon and into the evening hours. Storms are slowly drifting to the south and not able to hang around for too long due to the almost non existent shear over our forecast area. Some of the storms could become strong, but widespread strong/severe weather is not anticipated at this time. Expect to see some more fog form in the overnight hours, especially in sheltered locations and places that receive moderate rainfall this afternoon. Another similar story can be expected tomorrow with afternoon thunderstorms and slightly above average temperatures across the area. .Long Term (Friday night through Thursday)...Quiet weather will continue through much of the long term period with strong ridging continuing over the area. Diurnal convection is possible Saturday with a bit of weak moisture moving into the area. Showers/storms will be limited and mainly over the southern portions of the forecast area. Highs will remain near to slightly above average through the forecast period with the strong ridging in place. Ridging does look like it will break down late in the extended period with a trough and associated frontal boundary moving in for Thursday.
