065 FXUS64 KMRX 181100 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 700 AM EDT Fri Oct 18 2024 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 338 AM EDT Fri Oct 18 2024 Key Messages: 1. Ridging aloft and surface high pressure keeps us clear and dry. Discussion: Ridging aloft and surface high pressure continues to dominate our weather with clear sky conditions. Low-level heights will be on the increase today with temperatures being about 5 to 8 degF warmer than yesterday. For tonight, temperatures will be coldest across our sheltered valleys with a clear sky and calm wind. Patchy frost is expected once again across sheltered valleys of northeast Tennessee and southwest Virginia. && .LONG TERM... (Saturday through Friday) Issued at 338 AM EDT Fri Oct 18 2024 1. Warming trend above normal through Wednesday. Dry and Sunny. 2. Cold front Wednesday into Thursday. Uncertainty as far as any relief from dry conditions. Discussion: Ridge aloft over the east coast, paired with surface high pressure generally centered over the mid-Atlantic will maintain the dry weather across the area, as well as initiate a warm-up to above normal temperatures. Mid to upper 70s across the valley can be expected beyond Sunday. Even 80 degrees possible around Chattanooga Wednesday. The only change in the week comes Wednesday into Thursday when a shortwave followed by another shortwave and thus, surface front, approaches the area from the northwest bringing temperatures down a few degrees Thursday. The only uncertainty is if any precipitation will accompany this front. Right now, models paint it pretty dry. && .AVIATION... (12Z TAFS) Issued at 659 AM EDT Fri Oct 18 2024 High pressure will continue to result in VFR, clear conditions at all sites. && .PRELIMINARY POINT TEMPS/POPS...
