NWS Huntsville, AL wrote its last area forecast discussion before the first event at Sep 23, 5:25 PM CST, 10 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 625 PM CDT Sat Sep 23 2017 .UPDATE... For 00Z TAFS. && .NEAR TERM...(Tonight) Issued at 307 PM CDT Sat Sep 23 2017 Isolated showers continue to develop along the Cumberland Plateau in TN and weaken as they progress into northern AL. This activity will ween with sunset. Warmer than normal afternoon temps will cool down into the mid 60s tonight. With light winds and mostly clear skies, patchy fog is possible again tonight, especially in valley locations, near bodies of water and where rain fell this afternoon. .SHORT TERM...(Sunday through Monday night) Issued at 307 PM CDT Sat Sep 23 2017 Patchy fog will dissipate shortly after sunrise. Daytime highs will continue to be warmer than normal as we head into next week. An upper low anchored in the northern Gulf will lift northwest into central Mississippi on Sunday, with weak height falls across the TN Valley. This will allow temps to be a degree or two cooler than the past few days, mid 80s, and a few showers/storms Sunday afternoon, mainly in the western half of the forecast area. Monday on the other hand will be dry as a ridge to our northeast builds further south thanks to Hurricane Maria. .LONG TERM...(Tuesday through Friday) Issued at 307 PM CDT Sat Sep 23 2017 The TN Valley will remain under the influence of an upper level ridge and surface high pressure at the start of the long term period. Meanwhile, an upper trough will slowly eject east of the Rockies and push in the Central Plains on Tuesday, while TC Maria continues its slow northward progression off the Atlantic Coast. Given the high in place, dry conditions will continue through the day on Tuesday, with the continuation of above normal temperatures as highs warm into the upper 80s across the area. As the upper trough continues to move east on Wednesday, an upper ridge will build from the central Gulf Coast and into the TN Valley. Meanwhile, high pressure to the north will shift winds to a more northerly direction during the day. Temperatures will be hot once again due to the increase in thicknesses, however with northerly flow returning, dewpoints will be a couple of degrees cooler. The upper trough will essentially flatten as it moves into the area, leaving near zonal mid level flow across much of the region on Thursday and continuing through the weekend. A reinforcing cold front will swing across the area late Wednesday night, bringing a nice change across the area beginning as early as Thursday. As the stronger surface high builds in from southern Canada, cooler air will filter southward. Latest guidance shows very little in the way of precip with this front, as we get cut off from the moisture ahead of it and the forcing associated with the actual front remains weak. Therefore, have removed pops from the forecast on Thursday. Temperatures will be the noticeable difference behind the front, with highs on Thursday remaining near seasonal norms in the lower 80s. As the high continues to move southward, even cooler temperatures are forecast, with highs on Friday and Saturday struggling to make it out of the 70s. Dewpoints will also cool, and help overnight lows drop into the 50s for the latter part of the extended forecast period. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 624 PM CDT Sat Sep 23 2017 VCTS will hang on at KHSV for another hour, before dissipating quickly with the loss of heating. Moist boundary layer conditions overnight will result in some light MVFR/IFR fog development at each terminal, with the potential for brief MVFR conditions around sunrise at KMSL. Thereafter, a mostly clear sky and light winds will continue through the remainder of the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
