283 FXUS64 KMRX 131738 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 1238 PM EST Thu Nov 13 2025 ...New DISCUSSION, AVIATION... .KEY MESSAGES... Updated at 1235 PM EST Thu Nov 13 2025 - Low chances of rain Friday night, slightly better chances Saturday night into Sunday. - Breezy winds areawide this weekend with near wind advisory level gusts across the highest elevations of the east TN mountains. - Low to medium chances for rain next Tuesday. && .DISCUSSION... Issued at 1235 PM EST Thu Nov 13 2025 Not much change since the last forecast. Mostly dry weather into the weekend except for a slight chance of a light shower tomorrow night in southwest Virginia. This weekend, a weak front brings more light rain chances Saturday night into Sunday morning, but with no real push of cold air behind it. The biggest impact from this weekend`s system will be the breezy winds that will accompany it thanks to a 30 to 40kt 850mb jet that will be moving across the area. Deep mixing will allow breezy conditions across valley locations, lower elevations, of 15 to 20 mph wind gusts on Saturday and Sunday. The higher elevations of the east TN mountains will see gusts from 30 to 40 mph. Most higher elevation areas will stay below advisory level winds but isolated locations such as Cove Mountain may see gusts above 40 mph. A pattern shift next week is still expected but timing remains uncertain in regards to when a system will impact our area. Bottom line, increasing rain probabilities are expected next week but keep an eye out for further details once models better resolve their timing differences. && .AVIATION... (18Z TAFS) Issued at 1235 PM EST Thu Nov 13 2025 VFR conditions expected through the period at all sites. Breezy winds currently ongoing at TRI but wasn`t confident enough to include in TAFs as guidance suggest winds should be calming later in the day. Worst case, an amendment will have to be issued to include the gusty winds if they don`t subside. && .PRELIMINARY POINT TEMPS/POPS...
