Area Forecast Discussion
National Weather Service Morristown TN
259 PM EDT SAT JUL 30 2016

.SHORT TERM (Tonight and Sunday)...Scattered afternoon showers and
thunderstorms that develop this afternoon will slowly diminish after
sunset. However additional showers and thunderstorms will be
possible through tonight, particularly across southwest VA and
northern E TN, in response to a shortwave translating across eastern
Kentucky embedded within the broad eastern U.S. trough. Patchy fog
nearly forecast area-wide, perhaps a few locations and hours of
dense conditions will develop again tonight. Thickest fog will be
just before sunrise and break up a few hours after sunrise. Look for
overnight temperatures to range from the mid 60s north to lower 70s
south.

Similar pattern persists into Sunday with mainly afternoon showers
and thunderstorms possible. Maximum temperatures will range from the
mid 80s north to lower 90s south.

.LONG TERM (Sunday night through Saturday)...The forecast period
contains chance probabilities for a few showers and thunderstorms
each day through the long term. The pattern offers hope for some
needed rain as the models depict several disturbances riding
southeast out of the Upper Midwest in a favorably moist and unstable
atmospheric environment. Toward the end of the period a synoptic
cool front approaches through the Ohio Valley perhaps keeping
somewhat higher probabilities for convection going into next weekend.
The unsettled nature of the forecast with a few more clouds around
at times should limit any major heat wave action with high
temperatures topping out just a few degrees above normal through the
extended period.
