067 FXUS64 KMRX 011906 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 306 PM EDT SAT OCT 1 2016 .SHORT TERM (this evening through Sunday)...A good deal of clouds (5kft) over the Plateau and western Tennessee Valley. Limited instability around upper low across the upper Ohio Valley. Loss of daytime heating will allow clouds to dissipate some this evening with Partly cloudy sky anticipated. Patchy fog will be possible once again across the northern half of the area...mainly near area lakes and streams. For Sunday...upper low will move slowly northeast into the eastern Great Lakes with more sun and less clouds allowing temperatures to continue to moderate. .LONG TERM (Sunday night through Saturday)... High pressure will build back into the region early next week as an upper low slowly moves away from the area. This will bring an extended period of quiet, dry weather with warming temperatures. High temperatures will climb into the upper 70s to lower 80s. A weakening frontal boundary will approach the area towards the end of the forecast period. Models continue to show significant differences in the timing, amount of moisture, and strength of this boundary, so forecast confidence greatly decreases as the front approaches. For now, will continue to mention the chance for showers over mainly the northern part of the forecast area Thursday night and Friday. Additionally, models continue to indicate the potential for a hurricane off the east coast late in the week. Confidence remains quite low for this system and at this point models show little effect on the weather across our area, so have not included any impact from the storm in the extended forecast. && .PRELIMINARY POINT TEMPS/POPS...
