142 FXUS64 KOHX 151140 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 640 AM CDT Sat Jun 15 2024 ...New AVIATION... .SHORT TERM... (Today through Monday) Issued at 157 AM CDT Sat Jun 15 2024 Warm conditions once again across the mid state this morning. Temperatures are in the 70s, upper 60s Plateau. Patchy fog will be possible as we approach sunrise. Surface high over Lake Michigan will give us a light easterly/northeasterly flow for today. At the same time , however, an upper high will begin strengthening across the deep south. This feature will continue to strengthen as it moves to our east. A more uniform southerly flow will set up on Sunday and Monday with additional humidity expected. This will result in a returning chance of mainly afternoon and early evening showers and thunderstorms. Pops still look rather low with perhaps some 40% values on Monday. Best coverage appears to be across our west given that that area will be furthest from the upper high. The more important story will be the heat. The high will reach the Carolinas on Monday. Westward thermal extension will be in place, and with 850 mb temps in the 19-21C range we will continue to see highs in the mid to upper 90s. Sunday looks like the hottest day with 97F expected at BNA. The one Savior will be that dewpoints should remain in the mid to upper 60s. This should temper the heat index just enough to keep us out of any advisory requirements. As always though, we will need to play particular attention to areas along the TN river. Across that area, heat index values of 100-104F cannot be ruled out for Sunday. && .LONG TERM... (Monday Night through next Saturday) Issued at 157 AM CDT Sat Jun 15 2024 For the extended forecast, the upper high will reach the New York/New Jersey area on Tuesday. Ridging will extend southwestward toward our area and build with time. A moisture undercut will be possible, especially just west of Tennessee. NBM numbers just show 10 pops so it`s unlikely that precip inclusion will occur in the extended. But, that hot weather is going to continue. Look for mid 90s for highs through the period. Overnight lows will generally be in the 70-75F range. && .AVIATION... (12Z TAFS) Issued at 631 AM CDT Sat Jun 15 2024 A few passing clouds are possible today, but conditions will remain VFR across the area. Winds will be between 5 and 10 knots out of the northeast this afternoon before going calm overnight tonight. && .PRELIMINARY POINT TEMPS/POPS...
