.SHORT TERM /THROUGH SUNDAY/...
Issued at 344 AM CDT Sat Jun 28 2025

Even hotter temperatures today, with highs forecast to reach the
mid 90s most locations, and even the upper 90s far southwest.
This will lead to heat index values in the mid to upper 90s.

Thunderstorms are possible by late this afternoon, with one
focus along a pre-frontal surface trough, draped from near
Chamberlain South dakota through Valentine, back to the
southwest through Oshkosh in Garden County. Some of the latest
CAMs including the 3km NAM develop convection along this
boundary, especially from South Dakota into Cherry County. If
storms do form along this boundary, upscale growth may lead to a
cluster or clusters of storms developing southeast into north
central and possibly into west central Nebraska. Other isolated
storms initiating in the western Sandhills will move east
through the evening hours. Plenty of instability available, with
SPCAPES as high as 3000 to over 4000 J/KG. Large hail and
damaging winds, especially from outflow from storm clusters are
the main threats. Locally heavy rain is also possible, given
PWATs from 1.25 to 1.5 inches available. The activity should
move into portions central and eastern Nebraska late evening
into the overnight hours.

On Sunday, a cold front will push through the forecast area,
with cooler highs from the upper 70s to low 80s north central
to the the mid to upper 80s southwest. There a 5 to 8 degree
spread between the 25th and 75th percentile max temperatures,
so confidence in highs is below average. Regarding POPs, chances
increase to about 40 percent Sunday afternoon as the surface
front stalls near the Nebraska/Kansas border. There is also a
Marginal Risk for severe storms across the entire area, meaning
a few strong to briefly severe storms are possible.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Issued at 344 AM CDT Sat Jun 28 2025

After chances for showers and storms Sunday evening, Dry
conditions and seasonable temperatures in the mid 80s for
Monday.

Upper ridging builds into the region Tuesday through Thursday
with lows chances for storms. The upper flow becomes more zonal
by Friday (Independence Day), with increased chances for showers
and storms. Highs return to the low 90s Wednesday through
Friday.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1237 PM CDT Sat Jun 28 2025

The main aviation concern will be some convection development by
late afternoon into the evening hours. There is still some
uncertainty in timing and locations and therefore only VCTS has been
put in the prevailing forecast at this time. Strong winds and small
hail will be the main threats with these storms. Storms exit the
area by early morning with VFR conditions returning to KLBF. Some
stronger winds continue through the overnight across northern
Nebraska impacting KVTN with gusts up to 25 knots. Winds diminish by
sunrise Sunday morning.
