Area Forecast Discussion National Weather Service Nashville TN 508 AM CDT WED JUL 27 2016 .UPDATE... FOR 12Z AVIATION DISCUSSION. && .DISCUSSION... Convective parameters looking a little more favorable today as compared to yesterday. 18z lift is in place although the boundary is still off to our northwest. Also, cap erosion is apparent by 18z. Will include 40 to 60 pops for this afternoon. Rain chances will increase overnight as the upper trough axis amplifies along the spine of the ms river. Deep moisture and favorable omegas will combine, especially across northwestern areas by 12z with pops increasing to 70 percent. Looks like categorical pops during the day as the deep moisture spreads east and middle TN remains in a favorable pva zone. as far as any flood potential goes, the deep mrh levels will be rather narrow in scope. However, the highest mrh levels do linger across the northwestern portions of the cwa where 1 to 2 inches of rainfall will be possible through Thursday. Pops will back down a but by Friday as the aforementioned trough axis pulls east. Dew point levels will remain on the high side but high temps will back off a few degrees, especially on Thursday when highs should be no warmer than the lower to mid 80s. In the ext fcst, broad troughing to remain through Sunday with favorable cape to cap ratios each day. 00z omegas look neutral/favorable so pops will continue. Upper ridging will return around mid week with more in the way of 00z subsidence indicated. Only lower pops will be included. For the ext temps, values will run just a degree or two above normal. Good chance that warmer temps will return, however, by the end of next week. && .AVIATION... 12Z TAF DISCUSSION.
