Area Forecast Discussion National Weather Service Nashville TN 342 PM CDT Tue Apr 18 2017 .DISCUSSION... Scattered showers and thunderstorms will continue this afternoon, with activity beginning to decrease by 6pm. Some storms may contain gusty winds and heavy downpours, but should stay below severe thresholds. Precip is expected to be mostly east of the area by midnight. Another wave of showers and thunderstorms will be possible on Wednesday, however, coverage is expected to be less than today as the deeper moisture will be located to the south and east of Middle Tennessee. The main timing for any storms on Wednesday will be in the late morning and afternoon. Under partly cloudy skies and a light southerly wind, we should warm into the low to mid 80s Wednesday afternoon. Other than a few lingering showers and thunderstorms on the Plateau Wednesday evening, most of the area should be dry and remain that way through at least early afternoon on Thursday. The showers and thunderstorms expected on Thursday will be arriving just ahead of a weak cold front that is expected to slowly sink down from Kentucky early Friday morning through Saturday morning. High temperatures will vary from around 70 to near 80 degrees on Friday depending on how far south the front is able to make it. With the boundary bobbing over us Friday and Saturday morning, we'll likely see showers and isolated thunderstorms persist through both of those day. By Saturday afternoon the boundary should lift northward just ahead of an approaching surface low. Instability looks marginal with GFS soundings showing MUCAPE values around 800 j/kg, but bulk shear values around 50 knots by early Saturday afternoon. So thunderstorm chances will be fairly high throughout the day with some strong storms possible in the afternoon. Severe storms aren't out of the question, but if models continue to push the surface low south as they are trying to do, strong storms may be all we can muster up. Soundings are saturated and PWAT values are around 1.3 inches for most of the day on Saturday, so rainfall values of 0.5 to 1 inch will be possible. Thunderstorms may persist overnight Saturday night, but by Sunday morning only showers are expected. It may be Sunday evening before all the precip exits our southern and eastern counties. Temperatures on Sunday afternoon will be much cooler, with most areas only reaching the mid to upper 60s. Temperatures will rebound into the 70s for the first half of the work week next week and a nearby surface high should keep conditions pleasantly dry. && .AVIATION... 18Z TAF DISCUSSION. VCSH/VCTS at all airports today with prevailing -SHRA at BNA/CSV later this afternoon. Current MVFR cigs at airports will become VFR later this afternoon/evening, then return to IFR at CSV overnight.
