.DISCUSSION...
Issued at 1125 PM CST Fri Mar 6 2026

Current H5 analysis shows the mid/upper trough ejecting across
the central plains, with a 70+ knot H5 jet steak from west
central KS into NW Iowa. At the surface, the cold front is
making its way through the region right now, with a line of
showers and thunderstorms along the front moving into the KC
metro as of 1130 pm Friday. Straight line winds are the primary
threat, with the potential for a few QLCS mesovortices/tornadoes,
especially if the 0-3 km bulk shear vector can become oriented
more perpendicular to the convective line. The front should
completely clear the CWA by around 3 to 4 AM, with winds turning
northwesterly behind the front (sustained winds around 15 mph
and gusts up to 25 mph). Cooler, drier air will filter into the
region behind the front, with morning lows in the mid 30s to the
lower 40s for most locations. High temperatures for Saturday
should reach the low to mid 50s, with skies clearing from west
to east in the afternoon and breezy NW winds continuing into
early afternoon. High pressure builds in from the west by mid to
late afternoon, relaxing surface winds, and with light winds
and clear skies, radiational cooling will allow temps to drop
into the mid 30s CWA wide Saturday night into Sunday morning.

Zonal mid level flow returns on Sunday with higher mid level
heights building in and low level flow turning southwesterly and
increasing with gusts up to 25 mph. This will yield theta e
advection and help temperatures return to the mid to upper 60s
Sunday afternoon along with increasing dew points 5 to 8
degrees. A deep closed H5 low centered over Baja California and
another subtle shortwave trough translating across the plains
helps to increase theta e advection on Monday, with highs
reaching the mid to upper 70s and breezy southwesterly winds for
Monday afternoon.

As we head into Tuesday, the closed H5 low over Baja California
finally looks to become more of an open wave and eject across
the Trans Pecos and into the Southern High Plains. Meanwhile, a
cold front is progged to sag southward into the region along the
southern periphery of broad low amplitude troughing across the
north central Plains and into the Upper Midwest, with 40 to 50
knot WSW H5 flow taking hold over eastern KS and MO. Theta e
advection will continue, allowing dew points to rise into the
upper 50s to lower 60s by Tuesday afternoon, along with
temperatures reaching the mid to upper 70s. Showers and
thunderstorms are quite likely Tuesday afternoon, evening, and
into late Tuesday night into Wednesday morning (70 to 90
percent), and with sufficient forcing, moisture, instability,
and wind shear, a few storms could be strong to severe, with SPC
placing much of the CWA within a 15% risk area for severe
storms. Locally moderate to heavy rainfall will also be
possible. Storms should clear out from north northwest to south
southeast as the front pushes through the region Wednesday
morning. Temperatures should be much cooler on Wednesday, with
current model guidance suggesting highs in the 50s.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1125 PM CST Fri Mar 6 2026

The line of showers and thunderstorms along the cold front is
moving through the KC metro terminals at 530z, with it likely to
clear to the east of the terminals by around 7z. Heavy rain
reducing VIS and gusty westerly winds will come with the main
convective line. After FROPA, winds will turn northwesterly,
with sustained winds around 12 knots and gusts up to 22 knots.
MVFR CIGs are likely overnight tonight into Saturday morning
before improving to VFR by around 18z Saturday. Skies should
clear from west to east by mid afternoon, with winds becoming
light and variable by 00z Sunday.
