Area Forecast Discussion National Weather Service Nashville TN 218 AM CDT Sat Aug 15 2020
Upper level axis will shift to the east of the mid state by late afternoon. Still looking at favorable cape to cap ratios late today but moisture levels will be on the decrease, especially to the west of the Plateau. Furthermore, net subsidence should be the rule across western and central areas. Therefore, pops will only be included across the Plateau today, with max values of just 40 percent.
Tonight, looking rather non eventful. Patchy fog is a possibility overnight, looking most likely along the Plateau.
Now there is an expected fropa for Sunday afternoon. Forcing is looking rather weak but cape values will be on the climb during the afternoon. Given the timing of the fropa, best chance of showers and storms will be in the late afternoon hours across the Plateau. Given the weak dynamics will only include a 20-30 pop. Drier air to work in on Sunday night and Monday.
For the near term temps, looking seasonal today through Sunday. Then, a little cooler and less humid for Sunday night and Monday with lows mid 60s and highs mid to upper 80s.
In the ext fcst, upper troughing will persist though the period. At times, curvature and shear will be pronounced enough to evoke a few pva regimes. This translates into off and on shower and tstm chances. At this point, qpf amounts are looking rather light with just 30-50 pops, highest chances Plateau.
For the ext temps, with the troughing pattern anchoring in, looks like temperatures will run a couple degrees below normal. At any rate, expect a little break from the oppressive humidity that comes with those 70+ dewpoints.

Showers are continuing to dissipate across the area tonight, however with added moisture fog may develop overnight especially at KCSV. For now, have MVFR/IFR fog mention at KCSV and MVFR fog for KCKV/KMQY. Models suggest a MVFR/IFR cloud deck may move in overnight into the mid morning hours for all terminals, but not confident enough yet for predominant mention. Winds will increase by late morning out of the north around 10 knots gusting to around 15 knots through the afternoon. Chances for showers/storms should be confined to KCSV during the afternoon and early evening.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
