Area Forecast Discussion...UPDATED
National Weather Service Morristown TN
1000 AM EDT THU MAY 26 2016

.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.
