FXUS64 KOHX 210512 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1212 AM CDT Tue Apr 21 2026 ...New AVIATION... .KEY MESSAGES... Updated at 1209 AM CDT Tue Apr 21 2026 - No rain chances through Thursday. Middle Tennessee will enjoy plenty of sunshine the next several days. - A more unsettled weather pattern will emerge by Friday, with rain chances lasting through next weekend and into the following week. && .SHORT TERM... (Tonight through Wednesday Night) Issued at 1101 PM CDT Mon Apr 20 2026 Tonight should be a slightly warmer night, with lows in the 40s across the area. Some places near the AL state line and the Tennessee river will linger near 50 degrees. High pressure continues to dominate the forecast into the mid-week period, with warmer air coming into the mid-state beginning today. RHs could dip into problem territory for people with fire weather concerns, but the light winds we will see today should mitigate the need for any products. Highs today will get into the mid 70s to low 80s in Middle Tennessee under some partly cloudy skies. Same forecast for Wednesday, highs in the 70s and 80s with some lingering clouds that give way to a sunny day in the afternoon. && .LONG TERM... (Thursday through next Tuesday) Issued at 1101 PM CDT Mon Apr 20 2026 Our next rain chance will arrive into the weekend, and doesn't look to let up until the next work week. Since last night, some things have changed in the forecast. Firstly, probabilities for greater than or equal to an inch of rain over the entire weekend (Friday through Sunday) have gone down about 10% from what they were 24 hours ago. This follows the drying trend we have seen with past rain events in this drought: as we get closer and guidance gets a better handle on the system, the expected rain amounts decrease. As of now, probabilities for seeing greater than or equal to an inch in QPF through Sunday is around 30 - 50%. The second thing to change is the introduction of a possible marginal severe threat on Saturday. Can't say anything certain because of it being 5 days out, but some of the forecast soundings are interesting. 2000 J/kg of CAPE and 35 knots of shear is not shabby, but I'd like to see some better hodographs before messaging anything certain 5 days out. Certainly something to monitor as we get into the medium range guidance here in a day or so, and see if the trend continues. No matter if there is severe weather or not, there will be rain throughout the weekend, and into next work week. Temperatures will stay in the 70s for highs because of this, but will increase back into the low 80s by the end of the weekend. && .AVIATION... (06Z TAFS) Issued at 1212 AM CDT Tue Apr 21 2026 VFR conditions will continue for the TAF period. Winds will increase to 5-10 kts out of the SW in the mid-morning with gusts of 15-20 kts possible during the afternoon. These gusts will lessen after sunset. && .PRELIMINARY POINT TEMPS/POPS...
