.SHORT TERM...
(Rest of today through Saturday)
Issued at 1150 AM CST Fri Nov 28 2025

Longwave upper-troughing remains across much of the CONUS today
with a shortwave disturbance evident on water vapor imagery across
the Northern Rockies. This system is projected to move into the
Plains tomorrow fostering a strengthening low pressure system that
will move toward the Great Lakes Saturday night. A low-level jet
is expected to form ahead of the advancing cold front which should
support warm, moist advection and widespread light rain across
Middle Tennessee into Sunday morning. Rather light rainfall
amounts are forecast. We`ll also have marginal fire weather
conditions Saturday afternoon due to low RH values and increasing
southerly gusts prior to moistening boundary layer conditions.

Until then, it`ll be another cold night tonight with lows in the
20s.

.LONG TERM...
(Saturday Night through next Friday)
Issued at 1150 AM CST Fri Nov 28 2025

The longwave pattern will not shift much into early next week with
broad upper-troughing and passing shortwaves. In fact, a
subsequent shortwave is projected to advance across the Southern
Plains toward the Mississippi Valley on Monday. This appears to
favor cyclogenesis close to the Gulf Coast, though southerly low-
level flow is expected to spread northward into the Ohio Valley
where cold/dry air is in place. Once lower tropospheric saturation
occurs, wintry precipitation is possible, but is currently
favoring areas north of Middle Tennessee due to warming surface
temperatures within the surface trough. Nonetheless, we continue
to monitor for any snowfall accumulations as there`s a low chance
for accumulations across the northwest half of the area. Latest
LREF probabilities show a <40% chance for seeing at least 0.1"
(measurable snow), but only 10-20% chance of seeing 1.0" or more.
We`re currently not expecting any meaningful accumulations or
impacts for that matter. A good widespread soaking of rainfall is
likely, however.

The remainder of the forecast period appears cool, dry with
continuation of below-normal temperatures.
