Area Forecast Discussion National Weather Service Nashville TN 1241 PM CDT Thu Jun 15 2023 ...New AVIATION... .SHORT TERM... (Today through Saturday) Issued at 155 AM CDT Thu Jun 15 2023 Over the next few days, a ridge extending from the Southern Plains to Upper Midwest will build toward Middle TN. This will bring a warming trend with generally low rain chances. There will be a few disturbances that ride along the periphery of the ridge resulting in the potential for a few thunderstorms, mainly in the heat of the late afternoon and early evening each day. For today, there will be scattered coverage of storms, in the 20-40 percent range. We are not expecting severe wx, but of course any summertime thunderstorm can produce very local downpours and gusty winds. Rain chances will be lower for Friday and Saturday as the ridge strength increases. Chances will be about 20 percent Friday. The latest NBM (model blend) does not show any pops at all Saturday, but a very isolated storm cannot be completely ruled out. Temperatures will be slightly on the warm side of normal, but nothing extreme or unusual. Humidity will not be bad at all for this time of year. Heat index values will be near the actual temperatures. && .LONG TERM... (Sunday through next Thursday) Issued at 155 AM CDT Thu Jun 15 2023 Rain and thunderstorm chances will increase for Sunday as a low pressure system approaches from the Mid Ms Valley. A swath of deep moisture and greater instability will bring the likelihood for widespread rainfall and perhaps a few severe storms by late Sunday. Sunday evening will be our main concern for weekend events across the area. The low pressure system will then drift southeastward across TN Monday into Tuesday. this will keep a good deal of showers and thunderstorms in the forecast. Rainfall totals of 1 to 2 inches will be common from Sunday through Tuesday. The GFS moves the low away Wednesday, but the ECMWF keeps the low hanging over the area with unsettled conditions through all of next week. Low confidence this far ahead, but the upper level pattern across the U.S. does look stagnant, so we may end up with wetter than normal conditions throughout next week. && .AVIATION... (18Z TAFS) Issued at 1239 PM CDT Thu Jun 15 2023 Scattered storms have developed in the vicinity of BNA/MQY. Keeping VCTS for now, but may need to amend on storm trajectories over the next few hours. Some patchy fog is possible at SRB overnight, but outside of storms that may provide MVFR to IFR conditions for short periods of time, VFR should mostly prevail for this TAF cycle. && .PRELIMINARY POINT TEMPS/POPS...
