000 FXUS64 KMRX 230648 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 248 AM EDT FRI SEP 23 2016 .SHORT TERM (Today and tonight)...
-- Changed Discussion --
Persistence will be followed through the short term as high pressure at the surface will continue to sit over the Ohio Valley and Central Appalachian region, extending south across the TN Valley. The mid-to-upper ridge centered over the MS Valley will also remain nearly stationary today, and continue to provide a dry northerly flow that keeps clouds over NC to our east. Guidance and persistence agree that highs will be in the mid 80s north to lower 90s south today, and lows generally in the 60s tonight. .LONG TERM (Saturday through Thursday)... Quiet weather will be the main story for the first part of the extended forecast before we move into a more unsettled pattern next week. Under the ridge of high pressure and sunny skies, high temperatures will soar once again reaching around 90 in most places on Saturday. Very warm temperatures will continue through Monday until our next system moves into the vicinity. This system is a low/trough expected to move across the northern parts of the U.S. and a front to be dragged along behind it. However, models are still in poor agreement on the timing/strength/moisture of this system. So the current forecast has PoPs beginning to rise on Monday and sticking around through Wednesday. As the system gets closer and hopefully the models begin to agree on a solution this range of precipitation chances will likely shrink. In addition to the rain chances we will hopefully get several days of near normal to below normal temperatures for the second half of the work week.
