NWS Morristown, TN wrote its last area forecast discussion before the first event at Jul 4, 12:30 PM EST, 5 hours 38 minutes earlier.
Area Forecast Discussion National Weather Service Morristown TN 130 PM EDT Fri Jul 4 2025 ...New SHORT TERM, LONG TERM, AVIATION... .SHORT TERM... (This evening through Saturday) Issued at 129 PM EDT Fri Jul 4 2025 Key Messages: 1. Slight chance of a shower/storm in SW NC this afternoon, otherwise dry conditions continue through Saturday. 2. Slightly above normal temperatures but tolerable humidity levels. Discussion: An east-west shortwave trough axis is located across upstate SC and northern GA, which may lead to a few showers and storms developing in our SW NC counties in the next few hours. Satellite supports this as CU development is most vigorous in that area, and some very light returns are starting to appear on radar. This activity should dissipate by sunset. On Saturday, the mid/upper ridge will be building to it peak across the TN Valley, creating stable conditions that will be difficult for convection to overcome. Some CAMS are hinting at some isolated showers in the mountains, but the forecast will follow the NBM's dry conditions. Dewpoints today have dropped into the 60s in most spots with afternoon mixing, and that will likely happen again tomorrow, so humidity levels will be tolerable with high temperatures in the lower to mid 90s. && .LONG TERM... (Saturday night through next Friday) Issued at 129 PM EDT Fri Jul 4 2025 Key Messages: 1. Shower/thunderstorm chances increase each day through the first half of next week, with a potentially wetter pattern by mid week. 2. Increasing humidity with heat index values approaching 100 in the southern Valley Monday through Wednesday. Discussion: The ridge starts to loosen its grip a bit on Sunday as it gets pinched between a tropical low near the GA/SC coast and an approaching shortwave trough over the northern MS Valley and Great Lakes. Forecast soundings on Sunday don't appear as capped compared to today and Saturday, and low level moisture increases slightly. This should allow for a little better chance of afternoon showers and storms developing in the mountains. Monday looks similar, but with dewpoints possibly pushing into the 70s during the afternoon, the slight chance PoP spreads into the Valley. Heat Index values may start pushing toward 100 in the southern Valley as well. A front pushes across the OH Valley and toward our area late Monday as a broad troughing pattern sets up next week across the eastern Conus. This will allow for a greater chance of afternoon by midweek as the front gets closer to our area from the north. Doesn't look like we get an actual frontal passage, but with an eastern troughing pattern in place, the Atlantic ridge shifting westward, and the front nearby to our north, we could be setting up for a wetter pattern from Wednesday onward. && .AVIATION... (18Z TAFS) Issued at 129 PM EDT Fri Jul 4 2025 VFR conditions will continue to prevail through this TAF period, with light winds. && .PRELIMINARY POINT TEMPS/POPS...
