  large hail are the primary threats.

  of severe weather to Middle Tennessee Friday evening through the

  are the main concern.

- Unsettled weather continues next week.

.SHORT TERM...
(Tonight through Saturday Night)
Issued at 1002 PM CDT Thu May 15 2025

A surface and upper ridge are situated to our east, giving us a
southwest flow aloft while at the surface, a trough of low
pressure is situated to our immediate north and west. However,
there is a dearth of activity over Middle Tennessee this evening
owing to an unusually strong trapping inversion. It is expected
that the inversion will erode somewhat -- but probably not
entirely -- as the 00Z HRRR brings a cluster of storms into
northwest Middle Tennessee toward morning. However, the best
chance for convection is going to be late tomorrow, tomorrow
evening, then into the overnight hours across our eastern zones.
The aforementioned surface boundary looks to clear the mid state
entirely by 09Z Saturday morning. In the meantime, the
environment by tomorrow afternoon is likely to be highly unstable,
with large CAPE values, very steep mid-level lapse rates and
plenty of available moisture. There does look to be some low-level
wind shear, but tornadoes are of a lesser concern than damaging
straight-line winds and large hail owing to a unidirectional
profile.

.LONG TERM...
(Sunday through next Friday)
Issued at 1002 PM CDT Thu May 15 2025

Although the severe potential will be greatly reduced after
tomorrow night, low to medium rain and storm chances will stay
with us through the weekend and into the middle of next week
before a cold front on Wednesday brings us drier, cooler air for a
nice change.

.AVIATION...
(06Z TAFS)
Issued at 1224 AM CDT Fri May 16 2025

TAF sites will be VFR through the morning hours, when TSRA become
a concern and could drop sites into MVFR periodically. Winds will
be gusty tomorrow around 20 knots, but could be higher in
thunderstorms. TSRA will become widespread after around 20z, as
a line of storms moves from NW to SE across middle Tennessee.
