000 FXUS64 KMRX 261400 AAA AFDMRX Area Forecast Discussion...UPDATED National Weather Service Morristown TN 1000 AM EDT THU MAY 26 2016 .DISCUSSION...
-- Changed Discussion --
Showers associated with a midlevel shortwave trough are slowing moving east across the area...with a second line of thunderstorms developing in southern KY behind it. For the update...pops will be adjusted to better match current radar trends...but the question is what will happen this afternoon once this trough exits. Will this morning precip provide stabilization that will prevent additional development? The HRRR and RAP appear to say yes...and given the very dry air above 700 mb in the 12z OHX sounding...any CU that forms will have to overcome a lot of dry air entrainment. A slight midlevel ridge will also develop behind the exiting trough. So the update will have just slight chance pops in the southern half this afternoon...with low chance pops north.
