000 FXUS64 KMRX 140759 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 259 AM EST Thu Dec 14 2017 .SHORT TERM (Today and Tonight)...
-- Changed Discussion --
The strong...gusty winds are slowly diminishing across the area and the Wind Advisory should be allowed to expire at 15Z. The weather system moving through to our north will increase cloud cover this morning and may generate a stray area of flurries across higher elevations. Otherwise...it should be a quiet short term with flow aloft becoming zonal...winds continuing to slowly decrease and temperatures climbing into the 40s across the lower elevations this afternoon and falling into the 20s tonight. .LONG TERM (Friday through Wednesday)...Models continue to be in good agreement early on, with divergence of solutions and poor run to run consistency for the later periods, thus forecast confidence is good early on but suffers late. The long term period will start out Friday with some weak short wave energy pushing across, but with very little moisture so should see nothing more than some clouds with this especially north. High pressure will build in for Saturday. Models show moisture returning Sunday in the southwest flow ahead of a weak front. Models have been trending drier with this, so will just carry chance PoPs Sunday for some showers. Monday and Tuesday time frame will see some frontal boundaries in the area, but models disagree on the details. Looks warm enough for any precipitation to be all rain, and will carry chance PoPs Monday and slight chance Tuesday. Will go dry Wednesday for now as the second cold front should be to our east.
