493 FXUS64 KOHX 060655 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 155 AM CDT Thu Jun 6 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Friday night) Issued at 127 AM CDT Thu Jun 6 2024 Warm and very humid night across Middle Tennessee with current temperatures/dewpoints in the upper 60s to mid 70s. Just a few showers across the area on radar currently, but CAMs such as the HRRR indicate additional showers and possibly a few thunderstorms should pop up later this morning across our eastern half before moving out during the afternoon. Despite this precip, today looks quite warm with highs well into the 80s areawide. A cold front will push through the midstate tonight with a few showers possible along the front, before a much drier and cooler airmass arrives behind the boundary. Friday looks spectacular for early June with highs only in the mid 70s to low 80s, comfortable humidity with low dewpoints in the low to mid 50s, and no rain in sight. Friday night looks equally nice with the low dewpoints allowing min temps to drop into the 50s to around 60. && .LONG TERM... (Saturday through next Thursday) Issued at 127 AM CDT Thu Jun 6 2024 For Saturday, models continue to indicate a MCS across Missouri will make a run at us during the day. However, it will run into the dry and stable airmass in place over our region, and is anticipated to fall apart before or as it reaches or northwest counties. Main question is how far any precip with the MCS will penetrate into Middle Tennessee before it dissipates, but model consensus has only slight pops in our northwest for now. Another cold front will sink southward from the Midwest on Saturday night, with another loosely organized MCS shown to develop in southern Missouri then move across the midstate during the day on Sunday. This MCS should survive through our area thanks to deeper moisture, a stronger shortwave aloft, and the incoming frontal boundary focus, so expect fairly widespread showers and storms during the day on Sunday with high chance to likely pops. Forecast soundings do not show much instability and only weak shear on Sunday, so strong to severe storm threat looks very low attm. 00Z GFS/ECMWF show rain moving out of the midstate Sunday night, but will keep some slight chance pops into Monday until the front fully clears us to the south. Northwest flow aloft and a building upper level ridge looks to bring us a warming trend and lengthy dry period for the rest of the forecast period, with highs creeping back up to the 90 degree mark by Thursday. Models continue to suggest a tropical system could develop in the Gulf of Mexico by next weekend, but even if it does weak steering currents aloft and main polar jet stream near the Canadian border should keep any impacts to our south. && .AVIATION... (06Z TAFS) Issued at 1230 AM CDT Thu Jun 6 2024 Radar trends indicate showers continue to push eastward with minimal impact at TAF sites during the overnight hours. Might see a shower at SRB and CSV, but will have to watch for development approaching CKV, BNA, and MQY before winds shift to the west. After 12Z with winds shifting to the west, expect fairly clear skies which may allow for wind gusts to around 15kts. && .PRELIMINARY POINT TEMPS/POPS...
