Area Forecast Discussion National Weather Service Morristown TN 322 PM EDT WED JUN 15 2016 .SHORT TERM (Tonight and Thursday)...Convection across the area now will continue into the evening hours. Although early day clouds suppressed heating...patching clearing this afternoon has allowed temperatures to spike upward. Still expecting possibility of an isolated severe storm into this evening in a deep moist environment with CAPE values of 1400-1800 in GFS and NAM respectively. Overnight, convection expected to decrease in coverage and intensity but may see a few scattered showers and maybe a tstm persist into the early overnight hours. Guidance still hints at possible shower and thunderstorm activity in SW VA and NE TN on Thursday, however best instability and moisture shifts NE of the area as surface and associated low over northern Ohio shifts eastward toward the Middle Atlantic coast. .LONG TERM (Thursday night through Wednesday)...Active weather to start the long term with quiet weather to follow. Upper level trough with closed low and associated cold front will continue to drop down into the Southern Appalachians to begin the Thursday night period. Models show both favorable upper level and thermodynamic profiles for strong-to-severe storms to impact portions of the area. Best chances for stronger storms still appears to be up across NETN and SWVA, closer to the better upper level dynamics. SPC currently has the aforementioned areas under a slight risk for severe storms. Still some questions on severity of storms due to the timing of the cold front. Models generally indicate storms should arrive during the evening hours, while there is still some instability to utilize. If storms arrive later they will likely be weaker as instability really drops off toward midnight. Current timing looks like storms should move in from the north around 8pm. The amount of shear and instability differ between the GFS and NAM soundings but both suggest that the tornado threat can't be completely ruled out due to modest shear with approaching trough. Main threat at this time look to be damaging wind gusts due to dry mid level air and inverted v soundings at the surface. Again, best potential looks to be across northeastern Tennessee and our southwest Virginia counties. Some convection may drop down into the central valley along the cold front but not expecting the storms to be as strong due to further displacement from better dynamics. Front drops south through the area overnight Thursday and should be south of our area by late Friday morning. Upper level low rotating through the Virginias will allow for some additional pop chances through the day on Friday. High pressure begins to build in for the weekend with much drier air settling in. Dry weather continues through the work week as a large area of high pressure sets up across the central plains. Next chance for rain comes at the end of the long term period, late Tuesday night/Wednesday, as a cold front drops down out of the Ohio River Valley. && .PRELIMINARY POINT TEMPS/POPS...
