Area Forecast Discussion
National Weather Service Morristown TN

.DISCUSSION...Forecast on track for the most part with some minor
adjustments. Tweaked hourly POPs to match up with past few runs
of HRRR and radar trends as well as tweaks to temps and
dewpoints. Biggest change was to extend high wind warning until 3
AM EST across the higher elevations of the eastern mountains.
This is due to the frontal passage being a little slower than
previously forecast. The highest winds should be over with but the
warning area could still see some gusts up to 60 mph over the next
several hours. Nudged previous snowfall forecast downward
slightly due to slower frontal passage. The overlap between
available moisture and favorable temp profiles aloft aren`t that
long, maybe a few hours. Last thing, we did issue a flood warning
for the Sequatchie River as the river obs were coming in higher
than forecast. The new data we recently received from the RFC
took it into action stage, thus a FLW was issued. Everything else
on track, new zones out soon.
