.SHORT TERM...
(Rest of today through Thursday)
Issued at 1141 AM CST Wed Jan 22 2025

Strong high pressure is set up over the eastern half of the US.
That will bring a quiet day to Middle TN. After a very cold start
to the day with lows in the single digits flow will become more
southerly ahead of a digging trough to our west. This will help
to bring warmer highs than yesterday but they will still be cool
only making it to near freezing. We will see some passing mid to
high level clouds from time to time but plenty of sun throughout
the day.

Overnight lows will be warmer than last night falling into the
teens. Southerly flow will continue on Thursday and all locations
will warm above freezing with highs pushing to around 40. Clouds
will increase during the morning ahead of an approaching trough
with mostly cloudy skies developing during the afternoon.

.LONG TERM...
(Thursday Night through next Wednesday)
Issued at 1141 AM CST Wed Jan 22 2025

A long wave trough will swing through the region Thursday night
into Friday bringing another push of cold air. This air mass
won`t be as cold as the last one but we will see lows fall into
the teens Thursday night with highs in the low to mid 30s Friday.
Clouds will gradually decrease throughout the day Friday. This
push of cold won`t last long at all, flow becomes more westerly
over the weekend with temperatures becoming more seasonal.

A trough will dig into the Great Lakes on Sunday pushing some
moisture north. Warm air advection will develop Sunday morning
with light showers moving in. The trough axis and cold front move
through Sunday evening into Sunday night and will bring the peak
chances for showers. Overall this will be a light event with only
a few hundreths up to 0.25". No snow accumulation is expected
with this but can`t rule out some snow flakes mixing in Sunday
before daybreak with any showers and again Sunday night from I-40
north.

Weak ridging builds over the region for the first half of next
week. This will bring warming temperatures with highs pushing
into the low to mid 50s by mid-week. An upper level trough will
kick out of the West at some point mid to late next week and will
bring rain chances. Ensembles diverge on when and where this will
happen.
