000 FXUS64 KMRX 190312 AAA AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1012 PM EST Wed Jan 18 2017 .DISCUSSION... No major adjustments are needed to the forecast this evening. Ridging from 850 to 300 mb will be moving east of the Appalachians tonight, with a SW flow of positive theta-e advection and isentropic lift developing late tonight. As reflected in the going forecast, rain showers over MS are moving NE and are projected to reach our area between 09-12Z. The HRRR and RAP appear to have a good handle on this precip. Current obs match up pretty well with the forecast, and only a few slight tweaks to temperature and sky grids will be made. && .MRX WATCHES/WARNINGS/ADVISORIES... NC...None. TN...None. VA...None. && $$ DGS
