Area Forecast Discussion National Weather Service Nashville TN 340 PM CDT Sun Sep 9 2018 .DISCUSSION... A cold front, accompanied by clouds and showers, kept temperatures moderated today, especially in areas behind the front where cooler air was filtering in. At 3 pm, the cold front reached just east of Bowling Green and Nashville, southwestward to extreme northwest Alabama. Temperatures behind the front were only in the middle and upper 60s, with readings mainly in the middle 70s to lower 80s ahead of it. Wouldn't be surprised if some folks see a flash of lightning and/or hear a rumble of thunder over eastern areas tonight, as the front continues eastward. However, most of the precipitation will probably just be in the form of moderate to occasionally heavy showers. Recent model runs have consistently shown improving conditions for Monday, as far as precipitation is concerned, and now believe the best chance for showers will be early in the day, across the east. Even though the surface cold front will move east of the Mid-State by noon tomorrow, low level moisture and clouds will remain abundant, with skies remaining mostly cloudy for much of our area for most of the day. The best chance for a decent amount of afternoon sunshine will be over the northwest. As a weak upper trough remains over eastern Texas into Tuesday and Wednesday, expect patches of mid and upper level clouds to continue streaming northeastward across our area. The result will be varying amounts of cloudiness. Although Tuesday will be mostly dry, the chance for showers and thunderstorms will increase on Wednesday, especially over southern and eastern areas. Atmosphere remains sufficiently moist on Thursday to allow for some scattered mainly afternoon and evening thunderstorms. However, as we head into late week and next weekend, expect only isolated showers and storms, as clouds finally start to diminish as well. We may get a little assistance in the "drying department" from some subsidence along the outer fringes of Tropical Storm/Hurricane Florence by next weekend. This, along with developing northwesterly upper flow across our area, might even pull in some lower dew points and cooler temperatures toward the first part of the following week. The track of Florence is still somewhat uncertain, although NHC, the GFS and the ECMWF, bring it toward (or over) eastern North Carolina by next Friday. Any subsidence from that system for us will depend on how far west it goes. The more western movement progged by the ECMWF would tend to be more favorable in that regard. && .AVIATION... 18Z TAF DISCUSSION. A steady stream of showers are impacting Middle Tennessee sites this afternoon. Rain should begin to taper off at CKV over the next hour or two. BNA and MQY may see periods of heavy rainfall impacting visibilities and cigs through at least 21z, then taper off to vicinity showers into the early evening. CSV may be in store for several more hours of off and on rain as this band of moisture pushes east along with the cold front. Winds are out of the north behind the front and will gradually turn from south to north as the front passes later tonight at CSV. There is some question as to how much clearing we'll see early Monday morning, but right now models are holding on to some low level moisture. Even so, there could be patchy fog with IFR visibilities after midnight through mid morning on Monday at all sites. && .PRELIMINARY POINT TEMPS/POPS...
