DISCUSSION
ISSUED AT 355 AM CDT FRI AUG 29 2025
SATELLITE AND SURFACE OBSERVATIONS SHOW LOW CLOUD COVER (ALONG
WITH PATCHY FOG/DRIZZLE) CONTINUING TO SLOWLY FILL IN CENTRAL
NEBRASKA AND KANSAS. SOME LOCALIZED DENSE FOG REMAINS POSSIBLE,
ESPECIALLY IN LOW-LYING AREAS, THROUGH AROUND 10AM THIS MORNING. CLOUD
COVER IS EXPECTED TO BREAK UP ENOUGH FOR TEMPERATURES TO REACH
THE MID TO UPPER 70S THIS AFTERNOON...5-10 DEGREES WARMER THAN
YESTERDAY IN MOST AREAS.
A FEW SHOWERS AND THUNDERSTORMS COULD DEVELOP AS EARLY AS MID-
AFTERNOON, BUT ARE MORE LIKELY TO HOLD OFF UNTIL BETTER FORCING
ARRIVES FROM THE NORTHWEST IN THE 6-11PM TIMEFRAME. FAIRLY
STRONG DEEP-LAYER SHEAR (30-45KTS) COMBINED WITH MODEST
INSTABILITY (~1000 J/KG MUCAPE IN OUR FAR WEST) MAY ALLOW FOR
SOME UPDRAFTS TO SUPPORT MARGINALLY SEVERE HAIL/WIND. THE SEVERE
THREAT THEN WANES AS STORMS CONTINUE SOUTHEASTWARD ACROSS THE
AREA TONIGHT INTO EARLY SATURDAY MORNING.
SPOTTY SHOWERS/STORMS MAY PERSIST THROUGH SUNRISE ON SATURDAY.
CAMS SHOW SCATTERED STORMS REDEVELOPING AS EARLY AS 11AM-12PM
ON SATURDAY AS AN UPPER SHORTWAVE SLOWLY MOVES THROUGH THE AREA.
THERE WILL BE PLENTY OF DRY BREAKS DURING THE DAY ON SATURDAY,
BUT SCATTERED THUNDERSTORMS ARE EXPECTED TO CONTINUE THROUGH
MOST OF THE AFTERNOON AND EARLY EVENING. FORTUNATELY, THE
OVERALL SEVERE THREAT LOOKS TO REMAIN FAIRLY LOW. LOCALLY HEAVY
RAIN WILL BE THE PRIMARY THREAT.
COVERAGE OF RAIN/T-STORMS GRADUALLY SHIFTS EASTWARD WITH THE
SHORTWAVE SATURDAY NIGHT INTO SUNDAY MORNING. WESTERN AREAS WILL
TREND DRIER ON SUNDAY, BUT ADDITIONAL SHOWERS/STORMS ARE
ANTICIPATED TO REDEVELOP OVER AT LEAST THE EASTERN HALF OF THE
AREA SUNDAY AND SUNDAY NIGHT.
POPS DECREASE ON MONDAY, BUT A FEW MORE SHOWERS/STORMS CANNOT BE
ENTIRELY RULED OUT AS THE SHORTWAVE FINALLY PUSHES OUT OF THE
AREA. IN TOTAL, GLOBAL ENSEMBLES FAVOR MOST AREAS TO SEE
BETWEEN 0.50-2.00" THROUGH MONDAY NIGHT.
TUESDAY IS EXPECTED TO BE MOSTLY DRY WITH SLIGHTLY BELOW-
NORMAL TEMPERATURES. HIGHLY AMPLIFIED NORTHWESTERLY FLOW AND
ANOTHER SHORTWAVE/COLD FRONT WILL BRING SPOTTY RAIN CHANCES AND
COOLER TEMPERATURES TO THE AREA FOR WEDNESDAY/THURSDAY.
ENSEMBLES THEN FAVOR ABOVE-NORMAL TEMPERATURES TO FINALLY RETURN
NEXT WEEKEND INTO THE FOLLOWING WEEK (SEPT 6-8).

FOR KGRI/KEAR AIRPORTS:
FOR KGRI/KEAR AIRPORTS:
- GENERAL OVERVIEW (INCLUDING WIND DETAILS):
THIS IS A SOMEWHAT TRICKY PERIOD WITH REGARD TO CEILING (AND TO
A LESSER/BRIEFER EXTENT VISIBILITY), WITH SUB-VFR CONDITIONS
EXPECTED TO DOMINATE MUCH OF THE FIRST 12+ HOURS (ESPECIALLY
KEAR), BEFORE AT LEAST LOW-END VFR LIKELY RETURNS THROUGH MUCH
OF THE LATTER HALF. AT LEAST LIGHT FOG COULD ALSO PROMOTE MAINLY
MVFR VISIBILITY FOR A A FEW-TO-SEVERAL HOURS (MORE FAVORED
KEAR). TOWARD THE FINAL 6-9 HOURS OF THE PERIOD FRIDAY
AFTERNOON-EVENING, SHOWER/THUNDERSTORM POTENTIAL COULD COME INTO
PLAY, BUT THIS IS QUITE UNCERTAIN. WINDS WILL NOT BE MUCH OF AN
ISSUE, WITH SUSTAINED SPEEDS THROUGHOUT THE PERIOD AVERAGING
MAINLY UNDER 10KT FROM A SOUTHERLY OR SOUTHEASTERLY DIRECTION.
- CEILING/VISIBILITY/PRECIPITATION DETAILS:
KEAR WILL LIKELY START OUT THE PERIOD WITH MVFR CEILING WHILE
KGRI IS MORE LIKELY TO HANG ONTO LOW-END VFR FOR AT LEAST A FEW
HOURS. BY 09-10Z, A POTENTIALLY RAPID DETERIORATION TO MVFR
(FAVORING KGRI) AND IFR (FAVORING KEAR) CEILING IS EXPECTED,
ALONG WITH PERHAPS MVFR VISIBILITY (IN LIGHT FOG AND PERHAPS
LIGHT DRIZZLE). ASSUMING THIS DETERIORATION DOES INDEED OCCUR,
THERE IS STILL SOME UNCERTAINTY REGARDING WHEN CEILING MIGHT
RETURN TO AT LEAST LOW-END VFR, BUT BASED ON LATEST GUIDANCE
HAVE MAINTAINED THE 20Z VFR EXPECTATION FROM PREVIOUS/00Z TAFS,
WITH AT LEAST LOW-END VFR CEILING TENTATIVELY EXPECTED TO
CONTINUE THROUGH THE REMAINDER OF THE PERIOD.
AS FOR SHOWER/THUNDERSTORM POTENTIAL DURING THE LATTER HALF OF
THE PERIOD, CONFIDENCE IS ADMITTEDLY QUITE LOW. THERE COULD BE
AT LEAST SPOTTY ACTIVITY IN THE AREA AS EARLY AS 21-00Z, BUT
OVERALL-BETTER POTENTIAL PROBABLY HOLDS OFF UNTIL VERY LATE IN
THE PERIOD (MORE SO AROUND/AFTER 03Z. CONSIDERED INTRODUCING
PROB30 FOR NON-SEVERE THUNDERSTORM POTENTIAL, BUT GIVEN THE
INHERENT UNCERTAINTY AND THAT THESE CHANCES ARE STILL BEYOND THE
FIRST 12 HOURS, HAVE KEPT OUT ANY OFFICIAL SHOWER/THUNDERSTORM
INCLUSION IN TAFS AT THIS TIME.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1230 PM CDT FRI AUG 29 2025
FOR KGRI/KEAR AIRPORTS:
GENERALLY POOR CONDITIONS THROUGH THE PERIOD AS MVFR OR LOWER
STRATUS WILL PERSIST AT BOTH TERMINALS WITH A CHANCE FOR -TSRAS
INCREASING DURING THE EVENING HOURS. FOR THE REMAINDER OF THIS
AFTERNOON...EXPECT SOME SLIGHT IMPROVEMENT IN CIGS WITH JUST A
VCSH OR -SHRA POSSIBLE THROUGH AROUND 30/02Z...WHEN
THUNDERSTORM CHANCES SHOULD BEGIN TO RAMP UP FROM THE WEST TO
NORTHWEST. GIVEN THE UNCERTAINTY IN TIMING...HAVE A PROB30 GROUP
FOR NEAR IFR CIGS/CB/MVFR VSBYS STARTING AT 30/02Z FOR KEAR AND
30/04Z FOR KGRI. THESE CHANCES SHOULD CONTINUE OVERNIGHT...WITH
SOME LIGHT BR POSSIBLY DEVELOPING AS WELL...WITH ONLY SLIGHT
IMPROVEMENT AFT 30/15Z...AS SHRAS AND -TSRAS COULD EXTEND INTO
THE DAYTIME HOURS. WINDS THROUGHOUT THE PERIOD WILL BE ON THE
LIGHT SIDE OUTSIDE OF ANY THUNDERSTORMS...GENERALLY 10 KTS OR
LESS AND PRIMARILY OUT OF THE SOUTH.
GID WATCHES/WARNINGS/ADVISORIES
