.DISCUSSION...
Issued at 308 PM CDT Sat Jul 20 2024

This evening into Sunday:
Scattered showers and thunderstorms have begun to develop
across the region this afternoon. In central Nebraska, as of
2:30 PM the area of showers extends from north of St. Paul, NE
northeast towards Norfolk. This activity and other
scattered/isolated shower thunderstorm development will persist
through the remainder of the afternoon and evening hours. Most
of this will be diurnally driven, supported aloft with a weak
lobe of vorticity rotating around the primary upper low to our
east. Due to the diurnal nature, expect overall coverage to
decrease into the late evening hours as the sun sets, although
because there is some upper support, some showers and
thunderstorms could linger. These are expected to be non-
severe.

Fog as we saw this morning is again possible Sunday morning. The
axis for the best chance for fog is from the tri-cities to the
northeast towards Columbus, NE. At this time, not expecting
widespread dense fog, but some areas may drop to dense (1/4
mile) at times. This should lift as mixing begins around 9-10 AM
Sunday.

Temperatures through Tuesday will be slightly below normal with
highs in the 70s to low 80s and lows in the upper 50s to low
60s. Scattered off and on shower and thunderstorm activity is
also possible, with around a 20% chance. Organized activity is
not expected.

Wednesday through Saturday:
Upper level ridging begins to build in from mid-week on. This
will result in dry conditions and temperatures warming. Temps
will steadily warm each day into the 80s and eventually the low
90s for the weekend.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1233 PM CDT Sat Jul 20 2024

For KGRI/KEAR Airports:

Conditions have improved at both terminals from LIFR to IFR and
now MVFR. MVFR ceilings will persist into the afternoon hours,
slowly improving to VFR later today/evening. Fog, reduced
visibilities and low ceilings causing IFR or lower (LIFR)
conditions are possible again tonight at both terminals.

There is a chance for scattered showers and thunderstorms this
afternoon, mainly driven by surface heating causing it to
diminish as the sun sets this evening. These could impact a
terminal, but will not be organized and will likely be added in
an amendment. Showers and thunderstorms are not expected to be
prevailing, but temporary.

Winds will be light and variable through much of the area, where
they do have some directional component, they will be light and north
to northeast.
