Area forecast discussion, Jul 20, 1:46 PM CDT, 1 hour 9 minutes before
Area Forecast Discussion National Weather Service Nashville TN 146 PM CDT Thu Jul 20 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This afternoon through Friday Night) Issued at 134 PM CDT Thu Jul 20 2023 A cluster of severe storms is currently racing across Middle Tennessee, producing widespread wind damage and power outages, while we're also experiencing an ongoing flooding threat. Fortunately, once these storms exit the mid state, it will bring an end to the worst of the days-long storms and heavy rain we have experienced this week. Lesser storm chances will continue tonight and tomorrow before ending altogether tomorrow night as a surface boundary dips south of the region. && .LONG TERM... (Saturday through next Thursday) Issued at 134 PM CDT Thu Jul 20 2023 Drier, cooler air will finally settle over Middle Tennessee to start off the weekend, and rain chances from Saturday through next week will be hard to come by, which will be welcome given the volume of rain that we've received this week. Temperatures this weekend will be several degrees cooler than normal, but look for readings to creep back up by the start of next week. By the middle of the week, we can look forward to highs in the low to mid 90s most areas, but dew points won't be excessive, so for now it doesn't appear that any sort of heat advisory will be in play. && .AVIATION... (18Z TAFS) Issued at 1220 PM CDT Thu Jul 20 2023 A cluster of severe thunderstorms is bearing down on the Nashville Metro Area, so the first order of business with the 18Z TAF's is to move these storms across Middle Tennessee. These storms do contain severe wind gusts, although the storm core(s) will likely stay north of BNA. We do expect a cessation of the active weather behind this line. Look for dense fog to develop overnight, along with low stratus in a few spots. && .PRELIMINARY POINT TEMPS/POPS...
