.SHORT TERM...
(Today through Wednesday)
Issued at 102 AM CDT Tue Sep 17 2024

Most of the area is clear tonight with the exception being along
the plateau when some mid and high clouds are working in from the
east. These clouds are associated with an upper low and associated
surface low centered over the Carolinas. There are a few light
showers noted on KMRX in East Tennessee. Some of those scattered
light showers could impact the eastern counties today as the low
takes a westward jog. For the remaining two thirds of the area,
the only benefits from the low will be a little more cloud cover
and highs about 5 degrees cooler than Monday.

The low will reach its most western point this evening before
starting to move east again. This will pull the shower chances and
the cloud cover back to the east as well. A light shower can`t be
completely ruled out on Wednesday in the far east, but chances
won`t be as high as today. For the rest of the area, expect plenty
of sun with a light northerly wind.

.LONG TERM...
(Wednesday Night through next Tuesday)
Issued at 102 AM CDT Tue Sep 17 2024

As the upper low opens into a broader trough Wednesday night,
Middle Tennessee will be on the back side of the trough with
ridging building from Texas northward toward the Ozarks. That
ridging will build eastward Thursday night into the weekend
allowing temperatures to warm into the upper 80s to lower 90s
starting Thursday and continuing through the weekend. The humidity
will be tolerable with dew points in the upper 50s to lower 60s.
With those dew points, expect low temperatures in the low to mid
60s. In regards to rain, chances will be very slim through early
next week.

MVFR CIGs are moving into E TN and will likely impact CSV/SRB
through the day today. BNA/MQY/CKV, should remain VFR through the
afternoon with some high level clouds streaming overhead. Through
the morning and early afternoon, light showers are possible across
the Upper Cumberland. Winds will be out of the N/NNE. Tonight,
IFR CIGs and VIS are likely across the Upper Cumberland including
SRB/CSV. BNA and MQY could see some periods of MVFR CIGs late
tonight as well, but confidence is lower with some uncertainty on
how far W the lowest CIGs will push west.
