Area Forecast Discussion...UPDATED
National Weather Service Morristown TN
947 PM EST Thu Jan 19 2017

.DISCUSSION...
The forecast is generally on the right track with the rain
spreading into our area, which is associated with a negatively
tilted upper trough and cold front aloft. Eastward progress of
these featrues is slow, and rain will linger past 12Z in our
northeast sections. Thunderstorm chances tonight are low and
appear isolated to the southern half based on model depictions of
weakening instability aloft as the showers spread NE with time. A
few tweaks to PoP/Wx grids and temperature grids will be made to
better match obs and latest LAMP guidance through Friday morning,
but no significant changes are needed.
