Area Forecast Discussion National Weather Service Nashville TN 231 PM CDT Sun Jun 24 2018 .DISCUSSION... Short term models are starting to line up a bit better for the convective potential this evening and overnight. Existing convection off to the west is associated with the strong upper shortwave trough, and has additional development to the east along a warm front. A few isolated to scattered thunderstorms will be possible in the warm sector over the mid state this afternoon, but chances will increase later this afternoon and evening as the upper shortwave moves eastward across KY. CAMs want to develop a MCV and bring it eastward and slightly southward, and looks to impact northern zones during the evening and overnight hours. The question will be how far south the extent of convection will develop, but it at least looks like areas around and north of I-40 will see stronger convection per CAM consensus. Any stronger thunderstorms that develop will have the potential for damaging winds and even some hail late in the afternoon and into the early overnight hours. Low level shear profiles are somewhat decent, so cant rule out an isolated tornado as well. After sunset, MUCAPE values do fall a bit, however around midnight shear values will increase slightly as the upper trough axis will be passing through the region and upper trough just off to our north. At this time, the 850mb LLJ will increase to around 30 knots, which doesn't seem like much, however should be enough to help sustain convection with the upper low and provide additional moisture to the system. PWAT values are very high, showing around 2 inches this evening through the morning Monday, and current dewpoints are in the low to mid 70s looking at obs. The MCV will be moving relatively quick, but with deep moisture, high freezing levels, and evenly distributed CAPE per model soundings, heavy rain will be a threat overnight especially in the northwest zones. Any training or slower moving convection will increase the threat of flooding tonight through the early morning Monday. Monday morning will see the upper low and MCV move off to the east, but should still be impacting the northern Plateau Monday morning. There may be some trailing showers and storms, but models mostly have drier conditions moving in from west to east Monday. Ridging looks to build in late Monday through early Wednesday, so expecting mainly a diurnal shower and thunderstorm threat Tuesday afternoon/early evening. Wednesday looks to have another upper trough move east across the Midwest, and drag a cold front through the mid state. Timing is a little off between models, so kept chance pops in for now during the day Wednesday. By Thursday, the trough moves off quickly and upper ridging/high pressure moves in just as fast. Diurnal convection cant be ruled out, but temperatures will be on the rise as the impacts of upper ridging are felt. Current forecast has highs in the low to mid 90s Thursday through Sunday, with isolated afternoon showers and thunderstorms possible each day. && .AVIATION... 18Z TAF DISCUSSION. CKV/BNA/MQY/CSV...On average, VFR to IFR ceilings expected with MVFR vsbys associated with impacts of shwrs/tstms. Several adms possible thru TAF period, especially 24/22Z-25/18Z onward. Went close to consensus model reasoning. Iso shwrs/tstm expected thru 24/22Z so will mention VCTS development at actual terminals as hard to predict actual terminal area impacts but believe potential in VCTS will at least exist. An initial round of shwrs/tstms should develop around 24/23Z CKV to 25/02Z CSV, with general impacts to terminal operations for around a 3 hour period. Model consensus is pointing out the potential of a couple hrs break after this. Air mass will continue to be unstable enough to support continued potential of VCTS. After this, expect an area of shwrs/tstms to approach NW portions of mid state approaching 25/06Z and move slowly SEWD across the mid state thru 25/18Z with persistent light to mdt shwrs and iso tstm expected at terminals. && .PRELIMINARY POINT TEMPS/POPS...
