High pressure at the surface promoting clear and calm conditions
tonight across the Tennessee Valley. A good night for radiational
cooling in this cold/dry air mass will drop temperatures into the
lower 20s in most locations by early Wednesday morning -- with a
few locations dropping into the upper Teens in a few sheltered
valley locations. Only minor tweaks made to the forecast as
everything appears on track. Make sure to bundle up as you head
out the door Wednesday morning.

.SHORT TERM...
(Wednesday through Thursday Night)
Issued at 1218 PM CST Tue Dec 3 2024

The models still indicate a powerful upper trough digging through
the lower Great Lakes driving another Arctic front southeast into
the region Wednesday night. Preceding the frontal arrival, west-
southwest flow and weakening upper disturbances traveling east
through the south TX into the Gulf South will result in
considerable lift, and moisture transport and rainfall across the
deep South Wednesday into Wednesday night. The rainfall may spread
as far northeast as the TN valley Wednesday night, but considering
the dry low levels, there remains some uncertainty on this. The
greatest HREF probability of widespread measurable rainfall will
be southwest of a Muscle Shoals-Cullman line. However, we will
continue to carry low chances further northeast as well. When the
Arctic front arrives, a few flurries could mix in atop the
Cumberland Plateau in Franklin County TN as well.

Another blustery day is expected Thursday behind the front, but at
least it will be sunny. However, temperatures will struggle to
peak in the upper 30s to lower 40s. Lows by Friday morning will
only be in the middle 10s to lower 20s. Wind chills will dip to
the 5-15 above range as well with winds of 5-10 mph persisting in
a few spots.

.LONG TERM...
(Friday through Monday)
Issued at 408 AM CST Tue Dec 3 2024

Global models generally suggest that a cold core upper vortex
will travel cyclonically through the Great Lakes region/New
England and into the Canadian maritime provinces early in the
extended period, with southwesterly flow aloft expected to
strengthen across much of the southern CONUS in the wake of a
trailing mid-level ridge. However, there are subtle differences in
the rate at which these processes will occur, which will
ultimately have an impact on when our region can expect to see a
warming trend and increasing chances for rainfall. Present
indications are that we will remain under the influence of a
modifying arctic airmass and dry through at least Friday night,
which has led to removal of light freezing rain across northwest
AL early Saturday morning. Light rain may indeed impact primarily
the southwestern portions of the forecast area at times on
Saturday and Saturday night, but at this point chances for rain
and perhaps a couple of embedded thunderstorms do not appear to
increase considerably until Sunday afternoon, at which time deep-
layer SW flow will strengthen ahead of a southern stream shortwave
trough (the remnants of a slow-moving cutoff low initially over
the southwestern CONUS). Highs will progressively warm from the
u30s-l40s Friday into the l-m 60s Monday, with lows rising into
the m-u 40s by early next week.

Mostly clear conditions will continue through the afternoon hours,
with SW winds between 5-10 MPH. Clouds will begin to filter into
the region after 00z late in the period, but ceilings should
remain around low-end VFR levels.
