.DISCUSSION...
Issued at 1201 AM CDT Tue Apr 14 2026

The forecast period begins with southwest flow over the region and
an upper level trough over northwestern Arizona. Low pressure
develops on the lee side of the Rockies overnight, lifting into
extreme southwestern Nebraska and central Nebraska by daybreak
Tuesday. Tuesday morning, a warm front develops as far north as
Omaha/Council Bluffs. Temperatures are expected to climb into the
80s behind the front and the 70s to the north of it. Heading further
into the day, the front will sag southward a little bit, nudging a
little closer to the NE/KS border.

Late afternoon into the evening, instability will increase across
southeastern Nebraska/southwestern Iowa. SBCAPE values of 2000+ J/kg
and MLCAPE values of 2000+ J/kg are expected. Storms are expected to
develop along the warm front during the evening, a few of which may
become strong to severe. Large hail and damaging wind gusts appear
to be the main concerns with any storms that are able to develop.
The severe potential could go into the early morning hours.

The active weather pattern will continue through the rest of the
week with another shortwave trough lifting out of the Four Corners
region Tuesday and reaching southern Nebraska/northern Kansas by
Wednesday morning. The low will remain over eastern Nebraska
Wednesday morning, with a few showers and thunderstorms possible
through the day. The low is expected to lift slightly to the north
on Wednesday, bringing some wrap around moisture to northern
Nebraska. PoPs will decrease southwest to northeast heading into the
evening hours as the low exits. A few isolated strong storms may
develop in the southeastern part of the CWA Wednesday evening.

Thursday is still expected to be a dry out day as a ridge moves
across the region. After the brief cool down (highs in the 70s) on
Wednesday, warm air advects into the region. Expect widespread 80s
for highs Thursday afternoon.

Friday will be a day to watch as we get closer to the end of the
week. Low pressure develops on the lee side of the Rockies with an
attendant cold front moving into the region. An upper level trough
over the Four Corners region will lift to the northeast into the
area by Friday night. The cold front will be ushering in much cooler
air with WAA and moisture advection ahead of it. There is still
uncertainty in where the cold front reaches and the timing of
everything. Strong to severe storms with this set up are expected,
with all hazards possible. There is still considerable uncertainty
in some of the forecast details for this period, so continue to
monitor the forecast for potential changes.

Cooler air pushing in behind the front will result in a cooler
weekend. Saturday morning lows will be in the 30s, with low 30s
expected from David City to Thurston and areas north. Those with
agricultural interests will want to keep an eye on temperatures.
Highs will struggle into the 50s for much of the area. A few
locations will not make it into the 50s. Saturday night/Sunday
morning will be cold once again with lows ranging from the mid-20s
to the mid-30s.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1227 PM CDT Tue Apr 14 2026

A warm front draped across the region will make for a tricky
wind forecast this afternoon. KOMA and KLNK currently reside
right along the front, with light and variable winds. Expect the
front to push farther north this afternoon, bringing
southwesterly winds with occasional gusts up to 20 kts.
Scattered showers and storms will be possible this evening and
overnight. While the best chance for strong to severe storms
will likely remain south and east of the TAF sites, a few weaker
storms could develop farther north. The best chance for thunder
at KOMA, KLNK, and KOFK will likely be after 06Z tonight and
into Wednesday morning, however confidence in storm location is
too low to include a mention at this time.
