Area forecast discussion, Jul 23, 3:40 PM CDT, 38 minutes before
Area Forecast Discussion National Weather Service Nashville TN 340 PM CDT SAT JUL 23 2016 .DISCUSSION... It's another hot and muggy day today across Middle Tennessee as some scattered thunderstorms have developed this afternoon giving some lucky locations a nice break in the heat. With quite a bit of high cloud cover today, many locations were able to keep a lid on heat index values, with most at or below 105F degrees. Showers and thunderstorms will continue through the evening hours although short range models tend to dissipate convection by 8pm. But then again, we all know how well these short range models have done pinpointing convection lately. But I do think there will be opportunities for these models to redeem themselves next week. Keep reading. Until then...there will be patchy fog again in the morning with Sunday looking to be a carbon copy of today. Of course, there is a lot of model disagreement in where storms develop and how much coverage, but regardless, do think the potential is there that Middle Tennessee will see more storms Sunday than today. With that said, extended the Heat Advisory only for locations west of Interstate 65 through Sunday at 8pm...mainly due to the fact that the past two days have been borderline reaching criteria of 105F heat index at best especially over the eastern areas. The upper ridge finally shifts west allowing a slightly more active pattern to develop over the area as several upper level disturbances pass over the region. As a result, higher POPs are expected resulting in High Temperatures being a few degrees lower. Think the threat for any heat index values nearing 105F will end on Sunday. Thursday and Friday...as the work week progresses so will the active weather pattern. Upper trough sets up over the eastern U.S. as I mentioned yesterday. This will be the best shot for showers and thunderstorms over the next 7 days as long range models continue to be in fairly good agreement with this pattern change. The good news is that with the extra cloud cover and precipitation around, High Temperatures will likely stay in the 80s/lower 90s. && .AVIATION... 18Z TAF DISCUSSION. Expect scattered showers and thunderstorms across the region through 01Z. Storms will move very slowly...quasi stationary. Winds will be light and variable this afternoon then calm overnight. Like last night...expect some areas of light fog between 09-12Z where vsbys could briefly be reduced to 3-5SM. && .PRELIMINARY POINT TEMPS/POPS...
