Area Forecast Discussion National Weather Service Nashville TN 1230 PM CDT Fri Sep 27 2024 ...New AVIATION... .SHORT TERM... (Rest of today through Saturday) Issued at 1108 AM CDT Fri Sep 27 2024 Tropical Storm Helene continues to move northwest across East Tennessee into Kentucky this morning, with radar showing light to moderate rain continuing ahead of the system across Middle Tennessee. As Helene moves to our north through Kentucky today and Fujiwaras around an upper level low centered near Paducah, bulk of the rain will shift into the western 2/3rds of the midstate and continue the rest of today into Saturday, although rainfall rates will decrease. We have seen 2 to 4 inches of rain across Middle Tennessee so far, and an additional 1 to maybe 3 inches can be expected through tomorrow. Despite the high rainfall totals, low rainfall rates and our antecedent drought conditions should continue to keep the flood threat low. Nevertheless, will keep the Flood Watch going through 12Z Saturday. As far as winds, tightening pressure gradient around Helene as it moves closer will cause surface southwest winds to increase this afternoon into tonight, and gusts to around 40 mph will be possible at times. As Helene weakens on Saturday, winds will subsequently decrease with gusts mainly 15-30 mph. Based on this, no changes were made to the wind advisory. && .LONG TERM... (Saturday Night through next Friday) Issued at 1108 AM CDT Fri Sep 27 2024 Widespread but generally light showers will continue on Sunday as the merged Helene and upper level low oscillates around the TN/KY border. By Monday into Tuesday, precip chances will begin decreasing from west to east as the Helene/upper level low combo finally gets kicked out of the region off to the northeast thanks to an approaching mid level trough. A strong cold front moving through the area on Wednesday will finally end precip chances for the rest of the week, with a much cooler Fall-like airmass arriving for late week with lows in the upper 40s and 50s and highs in the 70s to around 80. && .AVIATION... (18Z TAFS) Issued at 1225 PM CDT Fri Sep 27 2024 IFR/LIFR conditions will continue for the taf period. The remnant low from Helene is centered NNE of CSV currently with winds shifting to the SSW at CSV/SRB. The southward shift in winds will occur and MQY/BNA in the next hour. Winds at CKV will remain northerly through the afternoon before they shift to the west this evening. The gusts will be strongest at SRB/CSV this afternoon with gusts up to 30-35 kts. Gusts up to 25-30 kts will be possible at BNA/MQY/CKV. Showers will continue to linger through the taf period with IFR/LIFR cigs and IFR/MVFR vis. && .PRELIMINARY POINT TEMPS/POPS...
