.DISCUSSION...
Issued at 240 PM CDT Sat Jul 18 2026

This afternoon-Tonight...

Temperatures this afternoon are currently in the 90s with heat index
values expected to top out around 100 degrees. Two main areas of
isolated-scattered shower/thunderstorm development are possible this
afternoon-evening, though an isolated storm can`t be ruled out
across most of the area. The first is mainly along and north of
Highway 92 in Nebraska, with a second area possible for areas along
and south of a Stockton-Hebron line. Whatever showers/storms do form
look to be fairly brief and weak given poor shear. These summertime
pop up storms should wane around sunset as stability increases. Lows
tonight will be in the upper 60s to low 70s with light winds.

Sunday...

Ridging aloft over the eastern Rockies/western Plains continues on
Sunday. At the surface another hot and humid day is expected across
the area as temperatures climb into the 90s. Similar to
today/Saturday, heat index values reach the upper 90s to around 100
degrees during the afternoon/early evening. Will need to keep an eye
on the potential for a few scattered, non-severe storms to move into
far northern portions of the area Sunday night, though confidence is
too low to include in the forecast at this time.

Monday...

Monday remain on track to be the hottest day of the forecast period
as highs soar into the upper 90s to low 100s. It`s possible that
temperatures could be a few degrees too warm if dewpoints are slow
to mix out. Regardless of the exact high, dewpoints combined with
hot temperatures will result in heat index values in the 100s on
Monday. A Heat advisory will likely be needed for at least a portion
of the forecast area given the support for fairly widespread
low-mid 100s heat index values. A cold front pushes into the
area late Monday evening-night. An isolated storm is possible
along this front as it moves into northern portions of the
forecast area, but any storm will likely be on the downtrend as
it enters the forecast area given the time of arrival.

Tuesday Onwards...

Aloft a trough diving into the Midwest begins to transition the
upper level flow into a northwesterly flow regime on Tuesday.
While slightly cooler than on Monday, temperatures on Tuesday
remain hot as they climb into the 90s (warmest KS). Temperatures
sink towards their climatological normals Wednesday onwards
with highs in the 80s to low 90s. More widespread precipitation
chances (20-50%) arrive on Wednesday and continue through the
end of the forecast period. Details on these chances will become
clearer as we get closer in time.

For KGRI/KEAR Airports:

VFR conditions expected through TAF period. A brief shower/storm
is possible during the late afternoon-evening, with any storm
clearing by sunset. VFR/CIGS are unlikely to become sub-VFR in
storms given the weak/brief nature of any storm. Otherwise
mostly clear skies are expected with light and variable winds.
