A high amplitude upper system brought varied impacts across the Southern Plains from the 8-9th. A strong 30-50 knot low-level jet and tight surface pressure gradient developed on the northwestern periphery of a deep (sub-995 mb) low pressure center as it tracked across central Oklahoma during the evening of the 8th.

The episode as NWS OUN wrote it up.
A high amplitude upper system brought varied impacts across the Southern Plains from the 8-9th. A strong 30-50 knot low-level jet and tight surface pressure gradient developed on the northwestern periphery of a deep (sub-995 mb) low pressure center as it tracked across central Oklahoma during the evening of the 8th. This resulted in a corridor of non-convective high wind reports across western Oklahoma. Across northwestern Oklahoma, a period of snowfall (with trace to 3-inch accumulations) occurred that, combined with aforementioned periods of high winds, yielded blizzard-like conditions during the evening of the 8th. Scattered areas of light snowfall continued into portions of central Oklahoma during the morning hours on the 9th and provided for a hazardous morning commute due to slick and partially snow-covered roadways.

(This evening through Tuesday)
Issued at 358 PM CST Mon Jan 8 2024
Key Points:
*A significant winter storm will bring near-blizzard conditions
across northwest Oklahoma this evening.
*Snowfall accumulations of 1 to 3 inches are forecast across
northwest Oklahoma with locally higher amounts of 4 inches or
higher possible in the most intense bands of snow.
*Gusty northwest winds will occur this evening through Tuesday. The
strongest winds are expected tonight with 40 to 60 mph wind
gusts.
*Dangerously cold wind chills in the single digits and teens will
occur Tuesday morning.
Meteorological Details:
An intense mid/upper-level low (~30 deg C at 500 mb) across the
Texas panhandle will continue to move eastward across northern
Oklahoma tonight. There has been a slight trend southward in the
track of the low, which has increased the potential impacts across
northwest Oklahoma.
Snowfall: The consensus among High Resolution Ensemble Forecast
(HREF) is localized snow showers will move across northwest
Oklahoma this evening (~6 to 10 PM) as the upper-level low moves
eastward. There is evidence that these will be somewhat convective
in nature (i.e., cellular like showers and thunderstorms) with
steep mid-level lapse rates and attendant elevated instability. As
a result, it would not be impossible to have some thundersnow.
There has already been some lightning in close proximity to the
upper-level low this afternoon.
For snowfall amounts, there will likely be significant variation
in snowfall in short distances due to its convective nature. The
most likely scenario (50th percentile) among the suite of
convective-allowing models is ~1 to 3" of snowfall. The
reasonable worst case scenario (90th percentile) is ~4 to 6" from
any intense convective snow showers. There is a 10% chance of this
occurring in a given location within the Winter Storm Warning.
Snowfall rates are forecast to decrease as the low moves eastward
into north central Oklahoma, but some accumulations are expected
across the northern half of Oklahoma. Short-term trends will be
monitored to see if a Winter Weather Advisory will be needed to
the south and east of the Winter Storm Warning (e.g.,
Major/Dewey/Roger Mills/Alfalfa counties)
Wind: An intense, ~995 mb surface low will track Oklahoma tonight
with an attendant cold front (entering northwest Oklahoma around 6
PM/00Z). A tight surface pressure gradient, and strong cold air
advection (CAA) will allow for strong northwest winds behind the
cold front. Wind gusts between 40 to 60 mph are expected tonight
(strongest west central into northwest Oklahoma) with a gradual
decrease into the day Tuesday (they will still remain quite gusty
Tuesday).
The snowfall combined with the strong northwest winds will result
in near-blizzard conditions in the the most intense bands of
snow. The wind will also combine with the cold temperatures to
result in dangerous wind chills in the single digits and teens
Tuesday morning.
Any remnant snow will exit northern Oklahoma early Tuesday
morning. Skies should clear from west to east during Tuesday
afternoon with some recovery in temperatures.

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 358 PM CST Mon Jan 8 2024
Temperatures will quickly moderate Wednesday and Thursday with
rising mid-level heights and the eastward expansion of a low-
level thermal ridge across the Southern Plains. Above-average
temperatures are expected with 60s deg F likely across western
southern Oklahoma and north Texas by Thursday.
Another mid/upper-level trough will approach the Southern Plains
Thursday night into Friday with another chance for precipitation.
Depending on the track of the trough, winter weather will be
possible once again; however, there remains some spread among
deterministic and ensemble members on the track/evolution of the
system. Probabilistic guidance has a low chance (~20%) of at least
4" of snow across northern Oklahoma.
By late into the weekend into early next week (January 14 to 16),
there is an increasing probability of significantly colder, arctic
air moving into the Plains from western Canadian. At this point,
the most likely time of arrival is Sunday or Monday. This air mass
will likely be the coldest air of the season. The Grand Ensemble
(average of GEFS, GEPS, and ENS) suggests the potential for highs
in the teens. Dangerous wind chills below zero appear likely
during this period as well. There could be additional winter
precipitation chances with an active jet stream too.

.AVIATION...
(18Z TAFS)
Issued at 1115 AM CST Mon Jan 8 2024
A line of showers continues to move across eastern portions of
the area, affecting KDUA until mid afternoon. MVFR ceilings will
remain possible throughout the period at KSWO and KPNC, whereas
KOKC and KOUN will see ceilings improve over the next few hours. A
strong cold front will move through the area this evening, with
strong winds behind the front. A second round of precipitation
will follow this frontal boundary, but will only affect the
northern TAF locations. KWWR could see reduced visibilities due to
blowing snow overnight into the morning. Winds will peak at 30-40
mph with gusts up to 60 mph possible.

Snowfall accumulation of trace to 0.5-inch resulted in slick roadways and numerous vehicle accidents during the morning commute on the 9th. A relayed report from the Oklahoma Highway Patrol stated that a 20 to 30 vehicle accident occurred on Interstate 35 near the Seward Road junction.
Snowfall accumulation of trace to 0.5-inch resulted in slick roadways and numerous vehicle accidents during the morning commute on the 9th. This included two such events involving multiple semi-trailers (Interstate 44/Turner Turnpike and Interstate 35 at Interstate 240 junction). The former resulted in at least one indirect injury.
