Area Forecast Discussion National Weather Service Nashville TN 1049 PM CDT Tue Jul 21 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1045 PM CDT Tue Jul 21 2026 - Cooler and drier conditions arrive Wednesday and continue through the end of the week, though a shower or two can't be ruled out south of I-40 Wednesday and Thursday. - More widespread showers and thunderstorms expected Friday night into Saturday. No severe weather expected at this time. && .SHORT TERM... (Tonight through Thursday Night) Issued at 1045 PM CDT Tue Jul 21 2026 On the whole, things are finally starting to calm down. We still have thunderstorms south of I-40 and west of I-24 that are drooping southward and will likely hold together all the way into Alabama. However, even though there's still lightning and heavy rain with them, the severe threat is all but over. I'll assess the need for continuing the current Severe Thunderstorm Watch and I may be able to cancel it early. In the end, we had a few significant wind reports, but this ended up being a much more significant flooding event. Multiple areas in the Nashville Metro area saw flooded parking lots, roads and a couple water rescues. As we wrap up this event, the front associated with these storms is expected to slow to a crawl over the next 24 to 36 hours. While the severe threat will come to an end, folks south of I-40 will see at least a few showers Wednesday into Thursday. However, the bigger story will be the cooler temperatures. Low to mid 80s are expected on Thursday, which will be an amazing break from the heat of the last few days. && .LONG TERM... (Friday through next Wednesday) Issued at 1045 PM CDT Tue Jul 21 2026 By Friday, we start to see some additional energy interact with this boundary near the AL/TN state line. This will bring rain chances back to the area and keep temperatures below average through the first part of the upcoming weekend. The best/most widespread rain chances will be Friday night into Saturday. At this time, I don't see any severe weather indicators. Once the rain tapers off Saturday evening, long term guidance is suggesting the influences of ridging over the center of the country should shut off our rain chances and start to increase temperatures. There are some model differences in this happening, so fine tuning will be needed over the next several days regarding the forecast for the second half of the weekend into the start of next week. && .AVIATION... (00Z TAFS) Issued at 618 PM CDT Tue Jul 21 2026 The first 6 hours of this TAF cycle will be riddled with TS and gusty winds as a broken line of thunderstorms moves into TN from the north. These should come to an end for all terminals by 05-06Z this evening and while cats will improve after the storms for CKV/BNA/MQY, MVFR cigs will return around sunrise Wednesday at BNA/MQY. CSV/SRB will bear the brunt of longer MVFR cigs through the night and sticking around after storms until lunchtime on Wednesday. Winds outside of storms will be light and we will see a shift to the northwest/north after storms pass. With storms, winds may be gusty at times with northwest to north gusts of 30 to 40 kts. && .PRELIMINARY POINT TEMPS/POPS...
