632 FXUS64 KMRX 251510 AAB AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1110 AM EDT Thu May 25 2017 .DISCUSSION... A weak shortwave trough is bringing another shot of cool air and a weak cold front -- with some rain showers to most of the region today. The highest chances for rain will favor upper East Tennessee and Southwest Virginia which will be closest to the center of the low (located over eastern Kentucky). These showers there will peak in coverage and intensity between 18-00z, with tapering off occurring later this evening. The clouds and rain will keep high temperatures on the cool side and only in the low to mid 60s. Elsewhere to the south and west (across the southern Plateau and Valley), some breaks in the cloud cover will result in some better heating. Rain showers should taper off by the early afternoon there as well -- allowing highs to reach the low to mid 70s. As a result, have a strong PoP gradient for the afternoon. Have slight chance to below mentionable PoPs for areas south and west and Likely to categorical for areas to the north and far east. && .PRELIMINARY POINT TEMPS/POPS...
