.NEAR TERM...
(Today)
Issued at 234 AM CST Sun Dec 22 2024

A clear/cold start early morning across the Tennessee Valley, with
high pressure in control and a modified arctic air mass in place.
Yet another weak shortwave will ripple SE through the area later
today, bringing a reinforcing shot of cool air later today. This,
combined with the breezy northern winds, will make it tough for
temperatures to climb out of the 40s despite the sunshine. Forecast
highs in the mid to upper 40s will be common in most locations by
the afternoon. Be sure to bundle up if you plan on being outdoors
later today.

.SHORT TERM...
(Tonight through Wednesday)
Issued at 234 AM CST Sun Dec 22 2024

Another clear/cold night tonight will plunge lows into the mid
20s again by early Monday morning. A gradual warming trend will
begin Monday as a ridge of high pressure begins to amplify across
the Deep South and winds veer to the SE. With ample sunshine,
highs in the low to mid 50s will be common by Monday afternoon.
This ridge will shift east of the area Monday night, with
southerly flow setting up for Christmas Eve (Tuesday) and
Christmas Day (Wednesday), helping to advect in a warm/moist air
mass. With mostly sunny conditions, highs should make a run at the
60 degree mark Tuesday afternoon. Clouds will be on the increase
Tuesday evening/night ahead of an approaching mid/upper trough
from the lower Mississippi Valley. Moisture return will allow for
very low (10-20%) rain chances to creep into the forecast Tuesday
night, before increasing to around 40% Christmas Day,
particularly during the afternoon hours. Southerly flow will
maintain the milder temperatures in the upper 50s to perhaps 60
degrees once again.

.LONG TERM...
(Wednesday night through Saturday)
Issued at 234 AM CST Sun Dec 22 2024

Precipitation will taper off Christmas Night as the trough and
associated boundary shifts east. However, very little in the way
of an air mass change will take place. High pressure will build
back in from the south and east and we`ll maintain southwest flow
across the area. This will keep our daytime temperatures in the
low to mid 60s Thursday through Saturday as we maintain this
warm/moist air mass. We`ll also remain in an active pattern as
another shortwave ejects from the Southern Plains into the Ohio
Valley during a Friday into Saturday timeframe -- bringing better
chances (50-70%) for showers and likely a few thunderstorms
along/ahead of a cold front.
