National Weather Service Morristown Tennessee
932 PM EDT Mon Aug 19 2019


No changes for the evening update. Though isolated in nature,
afternoon convection did feature some fairly strong storms.
Downdraft cape was in the 1,000 to 1,300 j/kg range per the Storm Prediction Center
mesoanalysis website during the afternoon hours today. Thus the
stronger updrafts/storms today were able to produce some strong
winds in a few places when they collapsed. As of 9:00 PM this
convection had completely died off, with only some high clouds
from the last singular storm over Bledsoe and far western Rhea
County remaining.. for the overnight hours, expect similar
conditions to what was seen last night. Mostly clear skies, and
temperatures in the 60s to low 70s for overnight lows. As noted by
the day shift at shift change today, dewpoints were higher in
most places this afternoon than the same time yesterday. As a
result it is possible that some patchy fog will develop during
the pre-dawn hours. If it occurs it would likely be in the places
that received rainfall today. Added some fog to the aviation
forecast for the Chattanooga Airport but did not add this into the
forecast elsewhere as it should remain very isolated in nature.

Otherwise, the forecast appears to be on track and no changes were
