Area forecast discussion, Jun 14, 2:55 PM EDT, 1 hour 17 minutes before

Area Forecast Discussion
National Weather Service Morristown TN
255 PM EDT TUE JUN 14 2016

.SHORT TERM (Tonight and Wednesday)...Ongoing afternoon convection
will continue through the evening...generally staying south of
Morristown.  Convection should decrease in coverage and intensity
after sunset...but should continue to see scattered showers and even
a few thunderstorms into the overnight hours.  The lingering showers
and few storm may slowly lift northward...eventually reaching into
the TRI area.   Another round of thunderstorms is expected to
develop on Wednesday.  With greater instability...expect more
widespread coverage with the possibility of a few storms becoming
strong to marginally severe.

.LONG TERM (Wednesday Night Through Tuesday)...A shortwave trough
will move through the area around Wednesday afternoon/night...ahead
of a deeper closed low slated to enter the Ohio Valley during
Thursday evening. The initial shortwave will bring scattered
showers and thunderstorms to the area for wed afternoon and
evening. The deeper closed low will approach the Mid Atlantic
states late week...with convection chances in through Friday.
However, the Mid Atlantic coastal low pressure area will usher in
cooler and drier conditions in time for the weekend. Seasonably
summer temperatures will return during the new work week as high
pressure builds in from the west.
