Area Forecast Discussion

.DISCUSSION...

Isolated thunderstorms have finally diminished over eastern areas,
although a few showers and storms continue to tease our most
eastern areas. As a result, will probably keep a slight chc for
thunder over those areas through midnight.

Models keep convection currently near MS river west of our
forecast area overnight, and latest radar loops would tend to
support that idea. Nevertheless, we could see those storms lay out
an outflow boundary that could migrate into our western counties
near the Tennessee River later tonight, and set the stage for
some Sunday morning thunderstorm development in those areas after
the sun comes up.

Have updated grids to bring them more in line with current trends.
However, the overall change to the previous forecast will be
minimal.

00Z TAF DISCUSSION.

Looking at VFR conditions through the TAF period, with some wind
shear overnight, strong southerly winds tomorrow, and chances for
showers and thunderstorms moving in from west to east from mid
afternoon through the overnight hours. Winds will calm down
slightly overnight but still be around 10 knots gusting to 20
knots. Wind shear will move into the forecast during this time
with a strong low level jet around 2kft off the surface around 40
to 45 knots. Just after sunrise, winds will pick up to be
sustained around 15 to 20 knots with gusts over 30 knots by the
late morning/afternoon. Chances for showers and thunderstorms will
first impact KCKV after 21Z Sunday, and likely after 00Z for
KBNA. Therefore just have shra and vcts for KCKV after 21Z for
now.
