.DISCUSSION...
Issued at 342 PM CST Fri Dec 5 2025

Southerly surface flow lifts temperatures today back toward
seasonal expectations with highs around the area reaching near
40 to the mid 40s. Some portions of west central MO and east
central KS might touch 50 degrees this afternoon. Another pulse
of cold air moves in overnight cutting the warming trend, but
keeps the temperatures outlook fairly static minus far NE MO
where some places might struggle to eclipse freezing. Shortwave
ridging keeps much of the daylight hours dry.

Aloft a shortwave is expected to descend out of western Canada
developing a lee trough which progresses through the northern CONUS
overnight Saturday into Sunday. Guidance has been steadily
maintaining the northern track keeping the bulk of the
precipitation through IA with more ensemble members joining the
consensus increasing confidence. Some deterministic guidance is
even more pessimistic and suggests we might even stay dry. At
this point, we are still expecting some precipitation with the
system as it passes by to the north. Precipitation looks to be
concentrated north of I-70 and is expected to move into the
region after sunset Saturday continuing through Sunday morning.
With this northward track, temperatures stay warmer for longer
keeping most of the snow potential north of the US- 36 corridor
through the early part of the event. Far NE MO remains the most
likely area for notable accumulations were around an inch or two
of snow is expected. Everywhere else can expect to remain less
than an inch. Temperatures remain the primary driver of
precipitation transition (which is not that surprising). The
onset of sub-freezing temperatures is expected after midnight
across far northern MO progressing southward to around 3AM for
the KC metro. As this freezing line migrates south, rain is
expected to transition over to snow. Model vertical profiles
have shown the air temperature hugging the 0C isotherm, but
still show a fairly clean flip from above to below freezing.
This limits the sleet and freezing rain potential. However, any
slight warm nose could produce a small window of freezing rain.
Some models have shown a bit bigger of a warm nose be it from
upper level warm air advection or quicker low level cooling
which does increase the plausibility of a period of freezing
rain. The good news is that the window of freezing rain is quite
small and the flip from rain to snow should be fairly rapid.
Any ice accumulations are expected to be minimal most likely
affecting bridges and elevated surfaces.

Cold air advection on the backside of the system keeps below to
around freezing. Warmer air builds back in early next week as
ridging and southerly flow establish themselves. It is not
implausible for highs next Tuesday to reach the 50s for most south
of I-70. Another system looks to clip the northern part of the area
Tuesday night into Wednesday. Early projections show this system
behaving similar to the one on Saturday including the general track
and potential track deviations. Extended guidance wants to lift the
general jet stream axis further north which could potentially open
up access to a longer period of higher than normal temperatures as
mid-December approaches.

.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 513 PM CST Fri Dec 5 2025

Beneath a deck of cirrus stretching over most of the region, a
small area of MVFR stratus is still attempting to advance
north into the terminals from southeast KS and southwest MO.
There is a threat for fog and low stratus, which would result in
IFR conditions, around 12-16Z tomorrow areawide though
confidence in this occurring is quite low. The best chances
exist at KIXD, since it`s closest to where the stratus is
currently. Conditions will need to be monitored for categorical
restrictions at the Kansas City metro terminals and St. Joseph,
though they were left from the TAFs at this time.

VFR conditions will return areawide late tomorrow morning with
winds becoming southeasterly through the morning into the early
afternoon.
