000 FXUS64 KMRX 180824 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 324 AM EST Thu Jan 18 2018 .SHORT TERM (Today and Tonight)...
-- Changed Discussion --
Still a few clouds around in upslope fashion across the Cumberland Plateau and higher terrain across Southwest Virginia and Northeast Tennessee. Would expect dissipation with continued dry advection this morning leaving skies sunny in a higher pressure regime. Temperatures start out in the single digits and lower teens this morning but modification of the shallow arctic airmass will be dramatic with max temps rising about 20-25 degrees into the lower and middle 30s across much of the forecast area today. Unfortunately it will be another very cold night with strong radiation in a clear sky, dry air and light wind environment. Lows will drop into the teens late tonight. .LONG TERM (Friday through Wednesday)...Models continue to be in pretty good agreement overall for the long term, and run to run consistency is decent. Forecast confidence is again a bit above average for this time of year. High pressure will be in control to start, with plenty of sunshine for Friday and milder temperatures. A weak upper low will track by to our south Saturday, and may bring more clouds to the area. By Monday the next cold front will be approaching, along with a good chance for showers. Colder air will push in behind the front Monday night, with any lingering showers possibly ending as a few snow showers at least higher elevations although right now it looks like much of the moisture is likely to move out before it gets cold enough for any snow showers. Dry again for Tuesday and Wednesday as high pressure builds back in.
