Area Forecast Discussion National Weather Service Nashville TN 200 PM CDT Mon Jun 21 2021 .DISCUSSION... Strong thunderstorms have already developed for some of our northern counties with additional strong to possibly severe thunderstorms expected through the evening hours. A severe thunderstorm watch is in effect for those generally along and north of I-40. Main concerns for any strong to severe storm that develops will be damaging wind gusts and small hail. There is plenty of instability across the area, and shear looks the best in the watch area. Can't rule out an isolated tornado, but there is not substantial low-level rotation for this to be the main threat. The threat of severe weather (minus flooding) should conclude as we move into the late evening as storms will generally move to the NE and out of our area. While the damaging wind/hail threat will end, additional rounds of showers following our ongoing showers/storms could mean flooding issues. A big question that remains is where the heaviest rainbands set up and how long they train over a particular area potentially leading to flooding issues. If the heaviest rainbands move over the same area, this would likely spell some localized flooding issues. PWAT values are near 2" to our NW and 1.5" to our SE. This high of PWAT values coupled with several hours and rounds of rain leads to a flooding threat. The flooding threat would likely continue into the overnight hours, as additional showers linger across the area. Surface frontal boundary will clear the area overnight tonight, ushering out any lingering showers by tomorrow morning and in drier conditions for the next few days. Highs will be much cooler behind the front, with highs in the mid to upper 70s tomorrow and upper 70s to low 80s on Wednesday. Unfortunately, the pleasant weather can only last so long as surface winds will become southerly Wednesday night into Thursday, bringing back warmer temps and moisture to the area. Think most of the day Thursday will remain dry, but expect some scattered showers and t'storms to return to the area on Friday. This weekend into a least the first half of next week looks pretty unsettled as a boundary begins to set up over the area. An upper-level trough will slowly extend into the eastern half of the U.S., but will take several days to do so leaving us with southerly surface flow and plenty of moisture. Highs will remain in the mid 80s with overnight lows in the upper 60s to low 70s through the weekend. && .AVIATION... 18Z TAF DISCUSSION. VFR conditions will quickly deterioate to MVFR with RA/TSRA moving into the area this afternoon. Best TSRA timing appears to be 19Z-22Z for KCKV, 21Z-23Z for KBNA and KMQY, and 22Z-01Z for KCSV. Beyond this time frame, RA along with MVFR ceilings and visibilities will plague all taf locations except for KCKV (until 02Z) through at least 08Z. Conditions improve after 12Z with all sites returning to VFR by 18Z/22. && .PRELIMINARY POINT TEMPS/POPS...
