.DISCUSSION...
Issued at 400 PM CDT Fri Jul 11 2025

Skies have cleared across much of the area (except for
southeastern parts of the area), allowing temperatures to reach
the 80s in most spots. Visible satellite shows developing
cumulus in the vicinity of a cold front slowly pushing across
the Sandhills. CAMs keep any development along this boundary
relatively isolated, and weak shear should keep updrafts
disorganized and short-lived. Nevertheless, if storms
materialize this evening, one or two could produce some isolated
hail/gusty wind (primarily northwest of a line from Lexington
to Columbus).

Further west, more widespread convection will develop over WY/CO
in response to the upper shortwave. This activity is then
anticipated to move into central Nebraska/Kansas after midnight.
Increased shear should sustain these storms into Saturday
morning, but the question is how intense they will remain as
instability decreases. As such, the western half of the area has
the best chance to see severe hail/wind, and SPC has trimmed out
the Marginal risk to be primarily from Highway 281 westward.

Some showers/storms may linger in southern parts of the area
past sunrise Saturday morning, then skies will slowly clear
through the morning and afternoon on Saturday. The post-frontal
airmass will feature cooler temperatures, less humidity, and
pretty light winds. A very comfortable day for mid July!

Sunday and Monday trend warmer as ridging moves into the
central/northern Plains. Heat index values return to the mid to
upper 90s by Monday.

Thunderstorm chances return to the area on Tuesday as the next
upper shortwave and surface front move into the area. Machine-
learning severe probabilities are not overly impressive (5-10%),
but there is at least some risk for severe weather in the
Tuesday/Wednesday timeframe.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1237 PM CDT Fri Jul 11 2025

For KGRI/KEAR Airports:

Lingering MVFR ceilings should clear out of GRI within the next
1-2 hours, with VFR conditions expected through the rest of the
afternoon. Low chances for thunderstorms arrive this evening,
with better chances arriving late tonight. As these storms
depart, MVFR ceilings are favored through around sunrise on
Saturday (50-60% chance).

Winds remain out of the north through the period.
