Fire Weather Planning Forecast for Middle Tennessee
National Weather Service Nashville TN
333 AM CDT Tue May 18 2021

.DISCUSSION...

Moist southerly flow will be stacked across the mid state today. As a
result, some shower activity is in the forecast, though amounts
should remain rather light. Moving forward, an upper level high will
develop over the Carolinas and will extent its influence across our
area. This will lead to dry weather with a warming trend. Note that,
dewpoint depressions will approach 30F Thu though Sat, but min rh
values should hold at the 30-35% level.
