.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 342 PM CDT Mon Mar 30 2026
This afternoon, record highs are being recorded with temperatures
rising into the mid to upper 80s. Strong WAA is expected to continue
tonight ahead of a cold front which is currently extends from
northeastern Nebraska back into western Kansas. This will allow lows
tonight to only fall back into the upper 50s to mid 60s which is
about 5 degrees warmer than the normal high for the end of March.
There is a slight chance (15-25%) of a few showers and perhaps
thunderstorm across northern Missouri ahead of the front late
tonight. Tonight into tomorrow a upper level shortwave will dig from
the Canadian Rockies through the extreme northern Plains and into
the far Upper Midwest. This will sag the slow moving cold front into
the area tomorrow. Widely scattered showers and thunderstorms (30%-
50%) will be possible along the front during the day tomorrow
although convergence along the front will be weak. Highs ahead of
the front will reach the low to mid 80s with northwest Missouri,
where the front will pass earlier the day the "cool spot" with highs
in the low to mid 70s. Thunderstorm chances will increase tomorrow
night as a southwesterly LLJ develops and noses into the area. The
LLJ will override the surface front which will bisect the CWA by
tomorrow night. This will increase thunderstorm coverage and a few
storms may be strong enough to produce marginally severe hail as
modest instability of 1500-2000J/Kg will be available. In addition,
storms should be very efficient rainfall producers with PWATs in the
1.2"-1.4" range which is near the 90th percentile for late
March.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 342 PM CDT Mon Mar 30 2026
Storm chances will continue tomorrow night into Wednesday as the LLJ
weakens a bit but never stops nosing into the area. The surface
boundary will continue to bisect the area and will be the focus for
storm development. Highs will ridge from the 50s north of the
boundary (near Highway 36) to the lower 60s to lower 70s south.
Wednesday into Wednesday night a upper level shortwave trough will
move from the central Rockies into the central Plains. This will
force a cold front into the area with widespread showers and
thunderstorm expected. A few storms may be strong to isolated severe
as modest instability of 1000-1500J/Kg along with 30-40Kts of
effective shear will be available. Perhaps of more concern will be
the potential for additional heavy rain as PWATs will range from
1.4"-1.6" which is in the 99th percentile for early April. Shower
chances will the continue into Thursday morning as the upper level
shortwave moves through the area before we final dry out Thursday
afternoon into Thursday night with surface high pressure building
into the area. Highs Thursday will be in the 60s to lower 70s.
Dry conditions will be short-lived however as Friday, a strong upper
level trough will move out of the northern Rockies into the
northern/central Plains. This will force a strong cold front into
the area Friday/Friday night with another round of thunderstorms
capable of yet another chance of heavy rain. In addition, severe
storms may be possible as the latest output for the GFS produce
MUCAPE of 2000-2500J/Kg and effective shear of 40-50Kts. This will
need to monitored as the week progresses. With several rounds of
storms capable of heavy rain possible this weak rainfall totals for
through Saturday range between 2 to up to 5 inches around the
forecast area. This may lead to minor flooding and minor to moderate
river flooding.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 614 PM CDT Mon Mar 30 2026
While VFR conditions prevail overall, it will continue to be
breezy much of the TAF period. With increased/increasing surface
pressure gradient in place, winds will remain up overnight,
including gusts into the 20s kts at times out of the S/SSW. This
carries on into daytime Tuesday before a frontal passage after
18z. Winds quickly turn northerly to northeasterly during this
time, with sustained wind speeds similar to a few kts less than
prior and occasional gusts into the lower 20s kts.
