000 FXUS64 KMRX 231423 AAA AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1023 AM EDT Fri Jun 23 2017 .DISCUSSION...
-- Changed Discussion --
An active day across the Tennessee Valley/southern Appalachians. Morning showers will end soon as water vapor shows much drier mid-level air spreading into the Region. The drier mid-level air will help to destabilize the airmass, but relative warm vertical profile will keep ML CAPES between 400-800 J/kg. Strong low-level jet will remain across the region and intensify late today as the remains of Cindy move across the lower Ohio/Tennessee Valleys. The strong south/southwest jet (50-60kts) and circulation around low pressure will produce a high shear environment. Latest SPC outlook of the potential of damaging winds and isolated weak tornadoes will be a concern late this afternoon and evening. Due to the strong low-level jet and Cove Mountain already showing high winds, have issued a wind advisory for the Smoky Mountains through 05Z. Breezy/Windy conditions can also be expected across the rest of the area with speeds of 15 to 25 mph with gusts to 35 mph anticipated. Current forecast highs look good overall.
