Area Forecast Discussion National Weather Service Nashville TN 235 PM CDT SAT AUG 20 2016 .DISCUSSION... Scattered showers and a few strikes of lightning are present in the CWA. This activity is associated with large scale Central US trough. At the sfc cold front is expected to move through the area tomorrow morning. Rain chances and cloud cover will decrease from northwest to southeast. By the afternoon rain chances should be confined mainly south of I-40 and the plateau counties. 12z models were a little slower than the 00z runs with pushing the front through. People who are outside doing late afternoon yard work tomorrow should begin to feel a noticeable difference in humidity levels and a refreshing northwest breeze. Our streak of days above 70 degrees still looks like it will be broken tomorrow just before midnight leaving the streak at 49 days. Monday looks like a great way to start the work week with mostly clear skies, highs in the upper 70s on the plateau and low 80s elsewhere, and dew points in the upper 50s to lower 60s. Tuesday looks like another nice day that will be a couple degrees warmer and dew points temperatures that will begin to creep up again. Sfc high that will be anchored over the KY, IN, and OH area by Monday morning will slide east and be centered near the nation's capital on Tuesday. Models begin to diverge a bit on Wednesday with the GFS being more aggressive in regards to QPF. This is thanks in part to the GFS skirting a shortwave disturbance across the area with increased upper level moisture. Regardless, rain chances will return on Wednesday and Thursday. GFS and ECMWF both have another front moving into the CWA on Friday along with an associated rain chance. && .AVIATION... 18Z TAF DISCUSSION. BNA/CKV/CSV...Surface map at 17Z shows a cold front almost to the Mississippi River, with scattered showers moving across Middle & West Tennessee ahead of the boundary. Ceilings have recovered to VFR heights, and should stay that way until overnight and Sunday morning as the front comes through and brings a swath of MVFR ceilings. Showers will end from west to east tonight and tomorrow morning as winds shift around to the NW. && .PRELIMINARY POINT TEMPS/POPS...
