UPDATE
ISSUED AT 131 AM CDT SUN SEP 20 2026
SCATTERED SHOWERS/STORMS WILL MOVE INTO WEST/SOUTHWESTERN PORTIONS
OF THE AREA EARLY THIS MORNING. ALOFT A TROUGH IS CENTERED OVER THE
ROCKIES WITH WEAKLY ZONAL-NORTHWESTERLY FLOW OVER THE EASTERN U.S.
SHOWERS/STORMS WILL LIFT EAST/NORTHEAST ACROSS THE AREA DURING THE
DAY, WITH RAIN COMING TO AN END OVER NE PORTIONS OF THE AREA BY THE
LATE AFTERNOON HOURS. WIDESPREAD STRATUS AND RAIN WILL HELP TO KEEP
THE DAY SEASONABLY COOL. HIGHS IN THE 60S ARE EXPECTED ACROSS MOST
OF THE AREA, WITH TEMPERATURES IN THE LOW 70S ACROSS SOUTHWESTERN
PORTIONS OF THE AREA WHERE SOME SUNSHINE IS POSSIBLE.
A WEAKENING CLUSTER OF STORMS THAT DEVELOPS OVER WESTERN NE/EASTERN
CO MAY SNEAK INTO FAR WESTERN PORTIONS OF THE AREA THIS EVENING
BEFORE DISSIPATING. GIVEN THE ANTICIPATED WEAKENING TREND, STORMS
ARE EXPECTED TO FALL BELOW STRONG/SEVERE STRENGTH BY THE TIME THEY
REACH WESTERN PORTIONS OF THE AREA. OVERNIGHT, SCATTERED SHOWERS
ALONG THE NE/SD BORDER MAY SINK INTO FAR NORTHERN PORTIONS OF THE
AREA (ALONG/N OF HIGHWAY 92) THOUGH ANY ACCUMULATIONS WOULD BE
LIGHT.
TROUGHING PERSISTS OVER THE AREA ON MONDAY WITH LOW STRATUS LOCKED
IN PLACE OVER CENTRAL/NORTHERN PORTIONS OF THE AREA. UNDER THE
STRATUS HIGHS WILL BE CONFINED TO THE 60S.
SOUTHERN/SOUTHWESTERN PORTIONS OF THE AREA COULD SEE MORE
SUNSHINE, ALLOWING TEMPERATURES TO CLIMB INTO THE MID 70S. A FEW
SHOWERS MAY LINGER ACROSS THE AREA THROUGHOUT THE DAY, BUT MOST
AREAS LOOK TO REMAIN DRY. OTHERWISE SEASONABLE-SEASONABLY COOL
WEATHER PERSISTS THROUGHOUT THE SCHOOL WEEK WITH HIGHS GENERALLY
IN THE 60S AND 70S. PASSING DISTURBANCES WILL BRING OFF AND ON
CHANCES FOR SHOWERS/STORMS THROUGH THE END OF THE FORECAST
PERIOD WITH THE MOST WIDESPREAD CHANCES WEDNESDAY NIGHT-
THURSDAY.
DISCUSSION
ISSUED AT 236 PM CDT SAT SEP 19 2026
A LINE OF SHOWERS AND THUNDERSTORMS HAS DEVELOPED ACROSS WESTERN
PORTIONS OF THE AREA THIS AFTERNOON. THESE SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO RAPIDLY WEAKEN AND DISSIPATE AS
THEY TRACK EASTWARD THROUGH EARLY EVENING HOURS WITH A MORE
ROBUST LINE OF SHOWERS AND THUNDERSTORMS EVENTUALLY DEVELOPING
TO OUR SOUTHEAST LATER THIS AFTERNOON ALONG YESTERDAYS COLD
FRONT. IN GENERAL, THE 18Z HRRR SEEMS TO HAVE CAUGHT ON TO THIS
INITIAL LINE OF SHOWERS AND THUNDERSTORMS STRETCHING FROM DAWSON
IN TO FURNAS COUNTIES, AND LARGELY UPDATED THE POPS FOR THE NEXT
FEW HOURS TO REFLECT THIS.
LATER TONIGHT, EXPECT A CLUSTER OF SHOWERS AND THUNDERSTORMS
DEVELOPING ACROSS THE ROCKIES TO MOVE INTO THE PLAINS, BRINGING
A BETTER SHOT FOR SOME MORE WIDESPREAD SHOWER AND THUNDERSTORM
ACTIVITY OVERNIGHT. GIVEN LIMITED INSTABILITY AND SHEAR, THIS
CLUSTER SHOULD BE WEAKENING AS IT CROSSES THE LOCAL AREA, BUT
CANNOT COMPLETELY RULE OUT A STRONGER THUNDERSTORM ACROSS OUR
WEST INITIALLY, ESPECIALLY ACROSS AREAS WEST OF HIGHWAY 183.
FURTHER EAST, THUNDERSTORM COVERAGE WILL DIMINISH AND ONLY LIGHT
RAINFALL ACCUMULATIONS ARE ANTICIPATED BY SUNDAY MORNING.
AFTER A SEASONABLE DAY THIS AFTERNOON, EXPECT TEMPERATURES TO BE
ON THE COOLER SIDE OF CLIMO SUNDAY AFTERNOON, WHICH WILL MARK
THE START OF A PROLONGED PERIOD OF SEASONAL TO SEASONABLY COOL
TEMPERATURES ACROSS THE REGION. AT THE SAME TIME, THE FLOW ALOFT
WILL FLUCTUATE BETWEEN WESTERLY AND SOUTHWESTERLY, WHICH SHOULD
ALLOW MULTIPLE UPPER LEVEL DISTURBANCES TO CROSS THE LOCAL AREA
THROUGH THE PERIOD - BRINGING OFF AND ON CHANCES FOR UNSETTLED
WEATHER ACROSS THE CENTRAL PLAINS. IT CERTAINLY WILL NOT RAIN OR
STORM ACROSS THE ENTIRE AREA EVERY DAY, BUT EXPECT AT LEAST A
CHANCE FOR PRECIPITATION ACROSS THE LOCAL AREA WITH EACH PASSING
DISTURBANCE.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
ISSUED AT 1212 AM CDT SUN SEP 20 2026
FOR KGRI/KEAR AIRPORTS:
LOW-LEVEL STRATUS (EVIDENT FROM SATELLITE IMAGERY) IS IN THE
PROCESS OF MOVING IN FROM THE NORTH TONIGHT. CLOUD BASES
CURRENTLY HOVERING AROUND 1,000-1,500FT WILL BE EXPECTED TO
GRADUALLY DROP TONIGHT WITH CEILING POSSIBLE TO FALL BELOW 500FT
BETWEEN 12-18Z. CLOUD BASES WILL STRUGGLE TO SCATTERED OUT
ACROSS THE AFTERNOON HOURS TODAY. AS RESULT, IT APPEARS VERY
LIKELY (70-90% CHANCE) THAT CEILINGS WILL NOT RECOVER OUT OF
MVFR CLASSIFICATIONS FOR KGRI (POSSIBLE VFR WINDOW
{3,000-4,000FT BASES} BETWEEN 0-3Z FOR KEAR). OTHERWISE,
CEILINGS WILL BEGIN TO DETERIORATE ONCE MORE OVERNIGHT SUNDAY.
THOUGH A FEW OFF-AND-ON SHOWERS WITH ISOLATED RUMBLES OF
THUNDER WILL BE POSSIBLE THROUGH THE PERIOD (MAINLY
TONIGHT/SUNDAY MORNING), IT IS UNLIKELY FOR THE SHOWERS TO
LINGER OVER KEAR OR KGRI FOR LONGER THAN A FEW MINUTES TO HOUR.
SURFACE WINDS WILL MAINLY REMAIN OUT OF A NORTH-NORTHEAST
DIRECTION, BLOWING BETWEEN 5-15KTS THROUGH THE PERIOD.
