932 FXUS64 KOHX 281638 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1138 AM CDT Fri Jun 28 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Rest of today through Saturday) Issued at 1129 AM CDT Fri Jun 28 2024 The heat is definitely on in Middle Tennessee. High pressure is now situated to our east, so we`re picking up some return southerly flow that is sending our temperatures soaring while also slowly increasing our dew points. Tomorrow will be even more oppressive as a surface boundary closes in on Middle Tennessee from the northwest. We expect enough additional humidity tomorrow that we are going to issue a Heat Advisory for most of Middle Tennessee west of the Cumberland Plateau for tomorrow. In addition, we expect scattered convection to develop in the pre- frontal environment. While this may provide some temporary relief in some locations, we still expect many locations to reach a heat index of 105F+. It is worth noting that the SPC`s day 2 outlook does include a tiny sliver of a marginal risk across our northern counties, but out risk of severe storms on Saturday minimal. && .LONG TERM... (Saturday Night through next Friday) Issued at 1129 AM CDT Fri Jun 28 2024 Our chance for convection will peak on Saturday night and Sunday with the expected passage of the aforementioned surface boundary. So we will dry out by Sunday evening and we`ll also enjoy a sunny and much cooler Monday, but the heat will start to build back in by Tuesday, with above-normal warmth expected to persist the remainder of next week. && .AVIATION... (12Z TAFS) Issued at 556 AM CDT Fri Jun 28 2024 VFR conditions thru 29/12Z. Isolated shwrs/tstms afternoon hours possible Cumberland Plateau Region, but not enough confidence in development to mention impacting/vcnty either.

Light sfc winds shifting to prevailing S/light after 28/14Z with initial SKC conditions becoming BKN CI with sct CU/AC also expected SRB/CSV. && .PRELIMINARY POINT TEMPS/POPS...
