528 FXUS64 KOHX 281635 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1135 AM CDT Sun Apr 28 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Rest of today through Monday Night) Issued at 1131 AM CDT Sun Apr 28 2024 Full-on spring and almost-summer has arrived, Middle TN. (It looks like) Gone are the days of the chilly mornings and mid-60s afternoons. Even the 8-14 day outlooks have us warmer and wetter than normal. We`re now into the 80s every day and low to mid 60s each morning - unless you live on the Plateau, then you get to enjoy the coolish temps still. Today will be a warm, dry and breezy day with afternoon highs creeping into the low to mid 80s for most. Cu fields have already developed across the area and with a cap in place, we will remain rain-free. However, this will change tomorrow. All of the activity that has been going on upstream from us the last couple of days will finally reach the mid-state tomorrow afternoon. The good news is, the weather actually looks pretty benign when it gets here. By the time the active pattern gets here, we`ll be losing shear, lapse rates fall off and CAPE numbers should remain below 1000 J/Kg. This all spells thunderstorms, but nothing looks severe right now. As was mentioned in the AFD earlier this morning, if there`s anything that sticks out in forecast soundings, it`s PW values. Current progs show these numbers creeping above 1.50" late tomorrow afternoon. While I`m not overly concern about flooding, efficient rainfall could give a couple of spots in Middle TN a quick 2+ inches, leading to some localized issues. Just something to keep in mind. && .LONG TERM... (Tuesday through next Sunday) Issued at 1131 AM CDT Sun Apr 28 2024 Monday`s evening storms will be slow to move out of the area. Models want to hold onto rain/storm chances through Tuesday afternoon, especially east of I-65. Similar to Monday, we`ll likely see some sub-1000 J/Kg CAPE build into this area, but shear values remain unimpressive, so no severe weather is expected. We`ll catch a break from the storms Wednesday and Thursday, but both will likely be our warmest days of the week as an upper level ridge amplifies into the Ohio Valley. The NBM continues to be very aggressive with upper 80s west of the Plateau for Thursday`s highs and might be a tick higher with probs for getting to 90. If that happens, we would tie a 123-year record. Rain chances move back into the region on Thursday starting another couple days of active weather. For now, CAPE and shear remain unimpressive as there just isn`t enough time to destabilize before storms get here. Long way off, but as of now, severe weather looks unlikely. && .AVIATION... (12Z TAFS) Issued at 624 AM CDT Sun Apr 28 2024 VFR conditions through the TAF period. Southerly winds up to 11 knots overnight increasing after 13z to 10 to 16 knots gusting up to 24 knots. Breezy winds diminish after 00z. Periods of high level clouds with mid-level clouds developing this morning into the afternoon. && .PRELIMINARY POINT TEMPS/POPS...
