.DISCUSSION...
Issued at 212 PM CDT Sun Sep 6 2026

An upper ridge extends from Texas and New Mexico northward to
Nebraska. A shortwave trough has moved across Nebraska today which
has resulted in showers and thunderstorms and is now located over
northeast Nebraska. Some redevelopment of showers and storms is
beginning to occur across portions of the area and may continue into
this evening. High temperatures today are expected to range from the
mid/upper 80s to the mid 90s. Some areas may experience heat index
values around 100 degrees this afternoon. Low temperatures tonight
will be in the mid 60s to mid 70s with southeast winds around 5 to
15 MPH.

Winds will increase out of the south at around 15 to 30 MPH with
gusts up to around 40 MPH Monday afternoon as a surface trough
strengthens to the west of the area. High temperatures on Monday
will generally range from the lower 90s to around 100 degrees. Heat
index values will generally range from the mid 90s to around 104
degrees with widespread values near or above 100 degrees. Low
temperatures Monday night will range from the mid 60s to the
mid/upper 70s. Rain and storm chances increase (up to 70%) Monday
evening into Monday night from the northwest associated with a
shortwave and low-level jet and in advance of an approaching cold
front. Some of these storms may become strong to marginally severe
with large hail and damaging winds.

The upper ridge over the area will get flattened by an upper trough
moving over the northern Plains on Tuesday. A cold front will move
into the area on Tuesday. High temperatures across the area on
Tuesday could range from the mid 80s in the north to over 100
degrees in the southern portion of the forecast area. Heat index
values across southern and eastern portions of the area are expected
to be around 100 to 106 degrees. A Heat Advisory may be needed for
southeast portions of the forecast area. Some showers, and possibly
isolated thunderstorms, may linger through Tuesday morning across
areas along and behind the cold front. More redevelopment of showers
and storms is expected during the afternoon (up to near 60% chance)
and continuing into Tuesday night (up to around 80% chance). Some of
these storms may become strong to severe with large hail and
damaging winds due to instability, wind shear, and lift.

Cooler temperatures will be present on Wednesday behind the cold
front with highs in the upper 70s to upper 80s. Low temperatures
Wednesday night may get down to the mid 50s to mid 60s with clearing
skies and light winds. Fairly similar temperatures will be present
on Thursday as those on Wednesday. A warm up is expected on Friday
with highs in the mid 80s to mid 90s ahead of a cold front. The cold
front will bring temperatures down into the 80s and low 90s for
Saturday.

Winds are expected to become more easterly by 00z then back to

20%) of low ceilings and maybe low visibilities from around 03z
to 16z but did not have enough confidence to include at this
time.
