Area Forecast Discussion
National Weather Service Nashville TN
203 PM CDT Mon Jun 17 2019

.DISCUSSION...

A few showers and thunderstorms have popped up mainly in the far
eastern zones early this afternoon, with more storms expected this
afternoon. CAMs have more convection developing in the northwest
and east during the early afternoon, becoming more scattered
across the mid state for the remainder of the afternoon and even
the evening. Some strong to severe storms will be possible as
decent instability and a bit stronger shear compared to yesterday
will be in place across the region. Damaging wind gusts are the
primary threat with any stronger cells. Afternoon and evening
hours each day through Thursday will carry a risk for strong to
severe storms since the atmosphere will largely go unchanged and
remain unstable with diurnal help. As the upper trough moves
eastward across the western portion of the state this evening and
overnight, the LLJ should strengthen enough to allow for
additional showers and thunderstorms to develop and keep rain
chances in overnight as well.

As the shortwave trough continues eastward Tuesday, chances for
scattered showers and thunderstorms will continue, especially
during the afternoon as the trough axis will be directly overhead.
Models start to back off coverage of showers and storms late
Tuesday evening through Wednesday morning as zonal flow/weak
ridging moves in between troughs. It will be short lived as more
shortwave activity will help kick off afternoon/evening showers
and thunderstorms Wednesday. Chances look to increase and continue
Wednesday evening into Thursday as shortwaves seem to phase into a
slightly larger trough over the Midwest Wednesday night, and allow
a weak front to pass through the area Thursday.

Thursday night through Friday looks to primarily be dry as ridging
moves in overhead, however, afternoon convection may occur since
the front/trough will not do too much in regards to moving
moisture out of the area. Saturday may be dry as well, but despite
the ridge, weak disturbances within the upper flow may be enough
to again bring afternoon convection potential. By Sunday, the
ridge slides eastward a bit, and southwest flow aloft will allow
for higher chances for precip during the day Sunday. This looks to
continue through the day Monday as well. Models diverge quite a
bit next week, so wouldn't bank on any solution right now as the
GFS remains wet, the Canadian is dry, and the ECMWF is right in
between.

.AVIATION...
18Z TAF DISCUSSION.

Scattered SHRA/TSRA have already developed over the Cumberland
Plateau, so CSV will show VCTS and a tempo group this afternoon.
Elsewhere, TSRA development will be sct and mainly after 21Z, so
VFR will prevail.

A shortwave trough will move in late tonight, giving enough
confidence for prevailing MVFR with SHRA/TSRA at all sites, mainly
09Z-15Z.

Any TSRA could be strong to briefly severe. Localized hail and
convective wind gusts will occur.
