...New AVIATION...

.SHORT TERM...
(Today through Sunday)
Issued at 1254 AM CDT Fri Sep 20 2024

Some fog is just beginning to show up on satellite imagery and I
expect more to develop before dawn similar to last night. Today
will be similar to yesterday but a couple degrees warmer as upper
ridging continues to push in from the southwest. Highs will span
from the upper 80s on the plateau to the mid 90s for the warmer
parts of the area including Nashville. Heat index values will be
very close to the air temperatures thanks to the tolerable
humidity. The weekend will be more of the same as the ridge is
the dominant features. Patchy fog will be possible again tonight
and tomorrow night.

.LONG TERM...
(Sunday Night through next Friday)
Issued at 1254 AM CDT Fri Sep 20 2024

The ridge begins to flatten Sunday night as a trough moves from
the front range of the Rockies across the central plains. The
upper level flow will become southwesterly over our area with a
weak disturbance ahead of the shortwave trough on Monday. This could
encourage a few scattered storms to develop Monday afternoon. A
surface low will take form over the Midwest Monday night dragging
a weak cold front behind it. The cold front will move through
Middle Tennessee on Tuesday with some scattered storms ahead of
it. Behind the front, temperatures will drop to values closer to
average for late September with highs in the upper 70s to lower
80s and lows in the 50s to lower 60s.

VFR conditions will prevail today. Some patchy fog tried to
develop early this morning causing some periods of IFR, but has
since dissipated. Some remaining fog can be expected in low lying
areas this morning but should dissipate by 13z.
