600 FXUS64 KOHX 291813 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 113 PM CDT Mon Apr 29 2024 ...New AVIATION... .SHORT TERM... (Rest of today through Tuesday) Issued at 1146 AM CDT Mon Apr 29 2024 Pretty nice day out there. Plenty of sun, temps in the 70s, creeping towards 80 for many. However, it will all go downhill from here. Clouds will be on the increase this afternoon ahead of next weather maker due into Middle TN this evening. Models have been very consistent regarding this system. As storms move into the area, we`ll be losing the heating of the day (sub-1000 J/Kg CAPE), lapse rates get worse and shear drops off. This continues to spell general thunderstorms with this system. Is there the potential for a gust to 40 mph with any storm? Sure, but no severe weather is expected. Rainfall still looks healthy between tonight and tomorrow. I think 1 to 2 inches is still possible with a few pockets getting a touch more with the heavier convection. Some localized flooding issues will be possible, but nothing to write home about. Rain chances fall off pretty dramatically by noon tomorrow, with everybody becoming rain-free before sunset tomorrow. && .LONG TERM... (Tuesday Night through next Monday) Issued at 1146 AM CDT Mon Apr 29 2024 High pressure builds into the region pretty quickly on Wednesday and this will set the stage for some of our warmest temperatures of the year so far. Thursday still looks like the warmest and latest NBM probs show the chance of getting to 90 degrees at about 70% for BNA. With dew points in the upper 50s, it won`t quite feel like summer, but close. Remember, if we get to 90 at BNA on Thursday, it`ll be the first time since 1901. It still looks like Thursday night for the arrival of our next weather system. Models have been fairly consistent with this, as well. This should lead to periods of showers and storms throughout the day Friday and Friday night with activity getting out of here Saturday morning. Forecast soundings still look pretty benign, so no severe weather is expected at this time. Even if we do see a break Saturday afternoon and Sunday, there looks like a good chance of more rain moving in Sunday night or Monday. With this many chances for rain, it matches up well the above-normal precip forecast from CPC through the next 10 days. && .AVIATION... (18Z TAFS) Issued at 109 PM CDT Mon Apr 29 2024 VFR conditions through much of the afternoon, but flight categories are expected to drop as a line of SHRA/TSRA moves through the area. SHRA/TSRA will move through from west to east, finally clearing off the Plateau near the end of the current TAF period. Expect MVFR/IFR conditions for most overnight into early tomorrow. Southerly winds will slowly become north/northwesterly between 12Z and 18Z. && .PRELIMINARY POINT TEMPS/POPS...
