.NEAR TERM...
(Tonight)
Issued at 855 PM CST Sat Dec 6 2025

We had another below normal day where highs only got into the
lower 40s when norms are in the upper 50s for early December. Low
to medium chances for patchy fog is still expected tonight while
the sky is pretty much clear. Obs are already observing light fog
in a few locations. Will monitor trends to see if coverage there
become dense, but coverage should be limited by cloud cover
moving in after midnight or so. However, with temps falling into
the lower 30s, fog in place will become freezing fog. Be sure to
travel safely in fog, slow down and leave extra space between
vehicles. Lowered overnight lows by a degree or two into the upper
20s to lower 30s based off of ob trends. Might have not gone low
enough so will monitor obs to see if further adjustment is needed.

.SHORT TERM...
(Sunday through Tuesday night)
Issued at 855 PM CST Sat Dec 6 2025

Any lingering patchy fog/freezing fog issues will dissipate with
sunrise. We will warm up to lower 50s on Sunday, much closer to
seasonal values that we have been. That unfortunately, will be
short lived. The trough`s who center is located up in the Hudson
Bay will amplify on Sunday and the associated sfc low in the
eastern Great Lakes will pull a cold front into the region. The
cold front will enter the TN Valley Sunday night and bring low to
medium chances (20-40%) of rainfall with it that lingers into
Monday. Lows Sunday night will be in the upper 30s.

Behind the frontal passage, high pressure will build in and funnel
in the colder air with a northwesterly wind. Drier air will
decrease cloud cover, but highs on Monday will be back in the 40s.
Monday night will be 10-15 degrees cooler than the night before
with lows in the mid 20s under mostly clear skies. High pressure
will shift eastward on Tuesday, allowing southerly flow to return.
This will help daytime highs get back into the lower 50s.

.LONG TERM...
(Wednesday through Saturday)
Issued at 855 PM CST Sat Dec 6 2025

Wednesday may be the best day of the entire forecast as high pressure
at the surface will promote dry and mostly sunny conditions. As a
result, high temperatures will make a run at the 60 degree mark in
some locations by the afternoon. A fast-moving trough over the Great
Lakes will attempt to push a cold front south toward the region from
the Ohio Valley Wednesday evening into Wednesday night. This front
will probably struggle to make it all the way into the area, but a
secondary shortwave will interact with this feature and generate some
low chances (20-40%) chances for rain showers Thursday and Thursday
night. In wake of this system, a cooler, drier air mass will settle
into the area by Friday.

A broad upper-trough situated over southern Ontario will
become the dominant weather feature over the eastern CONUS late this
week into the weekend. Several subtle shortwaves will traverse this
feature, bringing additional reinforcing shots of cooler air into the
region. Highs on Friday will peak in the mid to upper 40s, with
overnight lows dropping into the lower 20s. Saturday looks to be even
chillier as high temperatures will struggle to climb above the 40
degree mark -- with lows Saturday night in the Teens being common.
Saturday night we may need to watch wind chills as readings in the
single digits in a few locations may occur along the higher terrain.
Regardless, it`s important to recognize that a spill of colder
weather and below normal temperatures will be favored late next week
into the following week for mid-December. Make sure you review common
sense safety rules for cold weather and make sure you`re prepared.
