Area Forecast Discussion National Weather Service Morristown TN 723 PM EDT Sat May 23 2026 ...New AVIATION... .KEY MESSAGES... Updated at 651 PM EDT Sat May 23 2026 - Daily chances of showers and storms exist each day through the forecast period. - Conditions will also be muggy with no relief in sight until possibly next weekend. && .DISCUSSION... Issued at 239 PM EDT Sat May 23 2026 General synoptic pattern will consist of ridging over the southeastern CONUS and troughing atop the western through the weekend. A quasi-stationary boundary will continue to lift north and east along with the associated precip shield that has brought fairly widespread rains today. A line of showers with the occasional embedded thunderstorm can be noted across middle Tennessee per this discussion. Some additional isolated to scattered activity is expected to pop up this afternoon, but the bulk of this will remain along and west of I-75 where a better MLCAPE gradient exists due greater time for destabilization post soaking rains. Locally gusty winds possible with any moderate to heavy downpours but severe weather unlikely. Additional impulse traversing mean flow aloft will continue to promote periods of showers and storms possible Sunday. Latest CAMs admittedly struggle with pin-pointing an exact area and time, but ultimately the afternoon and evening hours will experience the greatest probabilities. Though, the better chances for some morning precip will be along the southern plateau and valley. General thunderstorm type activity seems to be the most likely scenario given a lack of shear with no standout LLJ present, and poor mid-level lapse rates south of 6C/km. MLCAPEs near 1000 J/kg and PWAT values near 1.5-1.7"(near daily max per KBNA sounding climatology) in latest HRRR soundings suggest some locally gusty winds will be possible associated with precip loading in the strongest convection. As we head into the new work week, the upper-level flow begins to shape into an omega-block pattern. Additional disturbances traversing mean flow aloft and continued anomalous PWAT values will further promote daily chances of showers and storms throughout the forecast period. While temperatures will be seasonable, the high dewpoints will lead to a muggy and sticky feeling airmass for the period as well. && .AVIATION... (00Z TAFS) Issued at 651 PM EDT Sat May 23 2026 Showers and a few thunderstorms will be around during the period, although timing is difficult to determine for any given site. The chance for showers is expected to increase later tonight into Sunday first at CHA then TYS and finally TRI, and the best chance for thunder looks to be Sunday afternoon. MVFR cigs are likely to develop at CHA overnight and continue into Sunday morning before lifting. There is also a chance of fog/low cig development elsewhere with the best chance at TRI. Will include a tempo MVFR cig/vsby group in fog at TRI for a few hours toward sunrise. && .PRELIMINARY POINT TEMPS/POPS...
