Area Forecast Discussion National Weather Service Nashville TN 1231 AM CDT Sun Apr 6 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1231 AM CDT Sun Apr 6 2025 - A Tornado Watch remains in effect until 3 a.m. for portions of Middle Tennessee south of I-40. - The majority of Middle Tennessee not under the Tornado Watch has transitioned exclusively to a flooding threat. Numerous Flash Flood Warnings are already in effect. && .SHORT TERM... (Tonight through Monday Night) Issued at 936 PM CDT Sat Apr 5 2025 A surface boundary currently bisects Middle Tennessee from northeast to southwest. The deepest moisture is situated along and behind the boundary, and widespread rain with embedded storms is expected to last the night and well into the day tomorrow. Hourly rainfall rates are under 1/2" most areas, and even under 1/4" in quite a few spots, although higher rainfall rates are still occurring with the heavier cells. At this time, rainfall estimates across northwest Middle Tennessee for this entire event (going back to Wednesday) range from 5 to 11 inches across much of the northwest half of the mid state, with amounts falling off sharply in areas to the south and east of Nashville. Although it has begun to push eastward, the surface boundary is still taking its time exiting the region; it probably won't shift east of the Cumberland Plateau until sometime around mid-day Sunday. River flooding will likely continue into at least the first part of next week. Much cooler air is working its way into the area even now; CKV is already down to 54F, and high temperatures tomorrow will range from the mid 50s to low 70s due to the position of the slow- moving front. && .LONG TERM... (Tuesday through next Sunday) Issued at 936 PM CDT Sat Apr 5 2025 Fortunately, the weather pattern for much of next week will be blessedly benign, and that will give us the chance to start drying out. We probably won't see full sunshine again until Tuesday, and Wednesday should be much the same. We won't re-introduce any PoPs until maybe Thursday for a fast-moving, low-QPF frontal passage that should be gone by the start of next weekend. The coolest mornings look to be Tuesday and Wednesday, when we can look forward to a widespread frost/freeze. After that, we'll start to warm back up. && .AVIATION... (06Z TAFS) Issued at 1231 AM CDT Sun Apr 6 2025 Conditions will transition to IFR or even LIFR at all TAF sites overnight. These conditions will last into tomorrow, with ceilings below 1000ft. TSRA will continue overnight, with showers continuing into tomorrow. Winds will become steady out of the north at around 10 knots. && .PRELIMINARY POINT TEMPS/POPS...
