.NEAR TERM...
(Rest of Today)
Issued at 930 AM CST Thu Jan 12 2023

QLCS with embedded supercells continues progress east of the I-65
corridor into central and west central AL. At present pace, these
storms will exit the east by midday or shortly after. We will not
alter much of the forecast as we have been too busy, but for now,
the afternoon chances of a few more showers and thunderstorms
looks good at this point.

.SHORT TERM...
(Tonight through Friday night)
Issued at 328 AM CST Thu Jan 12 2023

The Wind Advisory expires at 4pm today, however winds will remain
breezy overnight. These northwesterly winds will usher in much
colder air behind the front. Enjoy the warm ahead of this front as
temps will tank tonight into the low/mid 30s and only warm up into
the upper 30s to lower 40s on Friday with lows below freezing
Friday night.

As low level wrap around moisture brushes the TN Valley, we could
see flurries to light snow. Light snow accumulations less than an
inch are possible mainly for portions of southern middle TN and NE
AL. Everyone else will see flurries or very light accumulations.
Unlike the last time we had snow, our temps have been well above
freezing, so the ground temps should be warm enough to melt snow.
Of course elevated surfaces like bridges/overpasses will freeze
faster/easier so use caution.

.LONG TERM...
(Saturday through Wednesday)
Issued at 328 AM CST Thu Jan 12 2023

Chilly conditions to round out the week continue Saturday, as high
pressure over the regions controls the weather. After a chilly night
with lows in the mid 20s, not as chilly on Sat is forecast with highs
rising into the mid 40s. NW winds in the morning could be a bit brisk
in the 10-20 mph range, especially higher terrain in the morning but
should subside all areas in the evening. Similarly cold conditions
are forecast Sat night with lows in the mid/upper 20s. Surface high
pressure that has been controlling the weather will move east of the
region Sunday. A return southerly flow and more sun than clouds
should help high temperatures rise into the mid 50s, with southerly
winds 5-10 mph.

Not as cool for Sun night as warmer air settles over the region.
Lows should range from the lower 30s NE Alabama to lower 40s NW
Alabama. For Martin Luther King Day / Monday, clouds return, in
advance of another system nearing from the west. This next system
(a part of the Atmospheric River that's been impacting the western
states as of late) will also bring chances of showers to the
Tennessee Valley, especially in the afternoon over areas west of
I-65. A bit warmer with highs in the mid/upper 50s. Numerous showers
are forecast Mon night, as deepest moisture from the system moves
over the area. Overall instability and shear looks too low to add
thunder.

Showers should taper off from west to east on Tuesday, as this system
exits to the east. A frontal boundary with this system should remain
north of the area, helping even warmer conditions be realized, with
highs rising into the low/mid 60s. A stormy zonal flow continuing
across the western CONUS will make for an unsettled week. Yet another
system in this seemingly endless parade of storms will bring more
chances of showers to the Tennessee Valley late Tue night into
Wednesday. Continued mild to warm for mid January continues as well.
Lows Mon/Tue night will range in the mid 40s to around 50, and highs
Tue/Wed in the low/mid 60s. Normal temperatures this time of year
are around 52/34.
