Lingering showers should gradually dissipate tonight as a
shortwave trough moves east and out of the Plains. Surface high
pressure is situated over the northern Plains and this leads to
a quiet start to Friday with gradually clearing skies and
temperatures in the upper 50s and low 60s. The aforementioned
surface high pressure begins to move off to our east Friday
afternoon. Partly cloudy skies and the return of southeast winds
push temperatures back into the upper 70s to low 80s during the
afternoon. Another shortwave trough swings across the northern
Rockies heading into Saturday. This strengthens lee troughing,
resulting in gusty southeast winds. This keeps temperatures a
bit warmer Saturday morning with 60s to start the weekend. By
afternoon, a weak disturbance moves out of the central Rockies.
This may produce a few thunderstorm over our area, but chances
are low and most of the day remains quiet. Temperatures continue
to be mild for one more day with low 80s across the area.

The first heat wave of summer builds across much of the central
and eastern US beginning this weekend. The worst of this heat
arrives Sunday into Monday. Strong south winds under the ridge
will help to push warmer temperatures and higher dewpoints
north. The strong winds are driven by persistent lee troughing
with a large trough persisting over the northern Rockies. Each
day temperatures push well into the 90s to near 100 with
dewpoints in the upper 60s to low 70s. Peak heat indices in the
100s are likely for many. The highest heat indices may be as
high as 105 to 110 degrees. This level of heat may require heat
advisories in later forecasts.

The pattern only changes slightly heading into next week. Hot
and humid conditions are forecast to continue, though
temperatures will be a touch cooler. With changes to the
strength and position of the ridge anticipated, this may allow
for the return of periodic rain chances. The exact details
remain a bit uncertain between ensemble members, but at least
some threat of evening or overnight thunderstorms as
disturbances round the ridge appears possible. As confidence in the
forecast evolution of the ridge improves this weekend, expect
more details on the best chance for thunderstorms. Given the
hot and humid conditions, any thunderstorms will have plenty of
instability to work with, though wind shear is more marginal.
Severe weather remains a possibility with this environment.

VFR conditions with cigs up around 10,000-20,000 ft. Winds out
of the norht-northeast will shift easterly overnight, on to
southeasterly through Friday morning. We`ll be watching MVFR
cigs expanding northward from the south through the morning
hours. Guidance has locked on to these cigs lifting north
through at least KLNK with a 80% chance, while only a 40%
chance it gets as far north as KOMA. MVFR cigs will hang around
until clouds start to break up from the north during the
afternoon.

.KEY MESSAGES...

- Scattered showers possible through the mid morning hours with highs
  today in the upper 70s.

- Highs on Sunday in the upper 90s to around 100 degrees wit
  heat index values of 95 to 105 degrees.

- Hot and breezy conditions continue next week with highs in the
  90s and heat index values in the 90s to low 100s. &&

.UPDATE...
Issued at 228 AM CDT Fri Jun 26 2026

Scattered showers are ongoing across the area this morning under
overcast skies. Aloft a weak disturbance over the plains is embedded
within broadly zonal flow. Patchy fog currently located over
southwest Nebraska may sneak into western portions of the area
through the mid-morning hours, but dense or widespread fog appears
unlikely. Showers/fog will come to an end by the mid-morning hours
as the disturbance departs the area. Widespread stratus will be slow
to clear today limiting daytime heating, though sunshine returning
by the mid afternoon should allow highs to reach the upper 70s.

Another round of widespread stratus and fog develops over the area
tonight-Saturday morning. Within this stratus deck, drizzle or weak
showers are possible, though any accumulations will be
light/minimal. Similar to today, lingering stratus may be slow to
clear and lead to a slightly cooler day than currently forecast
(current highs low 90s southwest-low 80s northeast). Breezy winds
are expected during the day, gusting 20-30mph.

Southwesterly flow strengthens over the area on Sunday as troughing
deepens over the western U.S. Highs on sunday and Monday soar into
the 90s to around 100. Dewpoints in the 60s to low 70s combined with
highs results in heat index values topping out around 105 degrees
(near Heat Advisory criteria). Should the forecast remain on track
or increase slightly, a headline may be needed for a portion of the
area. Otherwise, southwesterly flow remains in place through the end
of the forecast period. This keeps above normal temperatures in
place with highs in the 90s and breezy winds each day.

.DISCUSSION...

For the rest of the day and overnight, scattered off and on showers
with very isolated thunder will be present through the evening
hours, tapering off overnight and towards Friday morning. The
latest guidance, including high-res ensemble guidance keeps the
bulk of any additional rainfall to the south and east of the
area. There is a potential that Rooks county could be clipped by
some stronger activity that slides southeast out of western
Nebraska and Kansas and could bring additional water concerns
if that does occur, but confidence is not high on that solution.

The upper level pattern shifts Friday as an upper low digs into
the Pacific Northwest. This causes the Central Plains to be
under southwesterly upper level flow with a low developing in
the lee of the Rockies. This will cause moist southerly return
flow to the region. The tightening gradient will keep winds
breezy at times, stronger than we`ve seen for a few days.
Likewise, temperatures will be much warmer, with highs quickly
returning to the upper 80s and low 90s for Saturday and then 90s
will be widespread on Sunday and Monday.

Model solutions indicate that 70+ dewpoints will surge back
north. The highest dewpoint values will be across eastern
Nebraska and into Iowa/Missouri, etc. That being said, this will
be quite a shock to the system after the cooler past week has
been. Heat index values exceeding 100 degrees are possible
especially along and east of Highway 81. Contrastingly, the
dryline will set up across western Kansas and the moisture
gradient will be visible where the drier air is able to mix out
and temps surge even higher...primarily western portions of
north central Kansas.

As June ends and July begins next week, temperatures look to
stay in the 90s while the trough persists out west with ridging
to the east of the Plains. Disturbances ejecting out of the
upper low in the west could cause a few sporadic precipitation
chances to impact the area next week, confidence in any details
is low.

There is an indication that the pattern will break down towards
the end of the work week and holiday weekend begins which could
allow for slightly cooler temperatures and rain chances over the
holiday weekend. Stay tuned.

Issued at 1237 AM CDT Fri Jun 26 2026

For KGRI/KEAR Airports:

MVFR to IFR conditions likely through the late morning hours at
KEAR/KGRI. MVFR stratus is building over the area with KEAR at
MVFR already and reaching KGRI in the next couple of hours.
Ceilings are favored to lower near IFR at KEAR, but remain
higher at KGRI. Confidence in KEAR reaching IFR conditions is
too low to include a TEMPO group but one may be needed if the
IFR stratus sets up near/over the area. MVFR stratus is favored
to linger through at least the morning hours, and the exact
timing of stratus clearing in the afternoon is uncertain. Have
opted to go on the later side of model guidance. Late in the TAF
period MVFR-IFR stratus may redevelop over the area, though
guidance favors it returning just past the TAF period.

Light and northeast winds shift to the southeast winds
throughout the morning hours. During the afternoon hours,
southeast winds increase to 10-12kts.
