.DISCUSSION...

The cold front has come and gone and it left behind an arctic
air mass across the Northern and Central Plains. Temperatures
as of 3 AM this morning sit solidly in the teens with northerly
winds gusting to 40 mph making it feel as cold as 5 below in
areas.

The upper-level pattern shows a deep upper-level trough over the
Northern Plains, with a ridge along the Gulf of Alaska helping
to force arctic air south into our region. As this ridge
continues to amplify, we`ll see enhancement in the northerly
Polar Jet enhancing the advection of arctic temperatures into
the Northern and Central Plains over the next few days.

Today we start out windy, with winds gradually weakening through
the day. Wind chills this morning will sit in the -3 to -15
range, warming into the single digits during the afternoon as
ambient air temperatures rise into the teens to low 20s. This
will be the warmest of the next few days as a second shortwave
moving through tonight will bring another reinforcing boost of
that arctic air dropping temperatures down below zero in many
areas by daybreak Sunday morning. Though winds will be weaker,
we`ll still have enough to make it miserable as wind chills drop
to a bone-chilling -15 to -30 Sunday morning. Hold on to your
hats (beanies?) as this will be the case for the next two
mornings as well.

For those who dislike snow, the good news is we won`t see any of
the white stuff during this cold snap, but we do need some snow.
It`s been a very dry winter so far, and that doesn`t appear to
be breaking through the next seven days. Temperatures during the
afternoons Sunday and Monday will rise into the upper-single-
digits to low-teens, though wind chill will keep it feeling like
temperatures remain below zero. We`ve issued a Cold Weather
Advisory through the period of Sunday - Tuesday morning to
highlight the dangerously cold temperatures expected.

As we go into midweek, we start to see temperatures rebound
Tuesday afternoon as the aforementioned ridge out west starts to
advance eastward into Alberta. This helps to push the cold air
off to the east. Tuesday afternoon we see temperatures rise back
up into the 20s in many locations. Wednesday we see another
shortwave move through with pre-frontal warm-air advection
bringing temperatures back up into the upper 30s to near 40 in
many locations. As we go into Wednesday evening, a handful of
the latest ensemble members do show some potential for light
snow as another cold front brings temperatures back down toward
seasonal normal or cooler for Thursday.

In the "beyond section" of the forecast, the trend seems to be
for cooler than normal temperatures to prevail with brief warm-
ups ahead of additional cold fronts bringing the cold air back
across our area. While nothing looks to be quite as cold as what
we are seeing this weekend into early next week, we could
potentially see chances for precipitation as the 6-10 day
outlook shows precipitation chances increasing back up to normal
with above normal chances in the 8-14 day outlook. This is
likely due to a upper-level pattern that continues to be active
through the next couple of weeks.

.AVIATION /12Z TAFS THROUGH 12Z SUNDAY/...
Issued at 428 AM CST Sat Jan 18 2025

Northerly winds continue gusting to 30 kt through much of today
with a few scattered patches of MVFR cigs hanging around
through around 15Z. These should retreat west of the terminals
into central Nebraska. Expect VFR conditions to hold through the
afternoon with winds finally weakening around 00Z this evening
to around 15-20 kt. Expect winds to remain out of the north
overnight with around a 30% chance of MVFR cigs moving in to
KOFK around 02-03Z, and a 10-15% chance at KOMA and KLNK.
