.DISCUSSION...

This evening and Tonight:
While this morning`s model guidance was a bit more robust, the
trend into the afternoon on the high-res hourly runs have
trended less active and more dry. This seems to coincide with
the assessment of the meso environment. The atmosphere across
much of central and south central Nebraska is impacted by this
morning`s lingering activity shower/thunderstorm activity. This
has created a cooler, more stable atmosphere with less shear.
Model simulations have trended to develop thunderstorms north of
the boundaries in the Sandhills, and then quickly dissipate them
as they move southeast. While this isn`t an all clear, the trend
is in the right direction for any evening 4th celebrations.
There could be some nuisance type activity primarily north of
I-80 this evening. Feel this is a 20-40% chance, that is lower
than I felt this morning when guidance was showing more robust
and organized convection.

Dry and seasonal for Sunday and the early part of the work week.
Upper level ridging builds in from the southwest. High temperatures
will be near 90 degrees.

By midweek, a couple of disturbances will move eastward,
breaking down the ridge and making the upper level flow more
zonal. This will bring more chances for off and on precipitation
through next Saturday. Beyond Saturday, more amplified upper
ridging builds into the intermountain west which will keep our
area under northwesterly flow and keep the potential for an
active period. Temperatures for the second half of the work week
are similar, with highs near 90, or slightly less in the upper
80s.

Issued at 559 PM CDT Sat Jul 4 2026

For KGRI/KEAR Airports:

Nearly all signs point to quiet aviation forecast period
for both KGRI/KEAR. Thunderstorms to the north and west
this evening will spill over some high clouds through
the evening and overnight. As of now, we aren`t expecting
those storms to impact KEAR or KGRI despite a slow drift
south.

Overnight in the KGRI area, there may be an increase in
mid-clouds as some weakish overnight convection could
develop to the east. For now, just some scattered clouds
were included.

Eventually, the high clouds will thin leaving nearly clear
skies Monday. No visibility restrictions are expected and
winds will be generally under 10 knots throughout the
forecast, with light and variable conditions through the
the night tonight, and a turn to the south/southeast by
Monday  afternoon.
