UPDATE
ISSUED AT 144 AM CDT SAT JUN 20 2026
CURRENTLY ACROSS SOUTH CENTRAL AND CENTRAL NEBRASKA AND NORTH
CENTRAL KANSAS TEMPERATURES ARE IN THE 50S AND 60S WITH LIGHT,
MOSTLY EASTERLY WINDS. SHOWERS ARE BEGINNING TO DEVELOP (MAINLY
ACROSS NORTH CENTRAL KANSAS AND THE NEBRASKA COUNTIES SOUTH OF I-
80). THIS ACTIVITY IS EXPECTED TO CONTINUE, EXPAND IN COVERAGE, AND
INTENSIFY WITH THUNDERSTORMS DEVELOPING (SOME POSSIBLY STRONG TO
MARGINALLY SEVERE). THE THREATS WITH THE STRONGEST STORMS WILL BE
HAIL UP TO QUARTER SIZE AND WIND GUSTS UP TO 60 MPH. THESE SHOWERS
AND STORMS MAY MOVE NORTH OF I-80 CLOSE TO/AFTER SUNRISE.
SHOWERS AND STORMS WILL CONTINUE INTO THE MORNING HOURS AND WILL
LIKELY MOVE/EXPAND FURTHER NORTH AND EAST. WHILE WIDESPREAD SEVERE
STORMS ARE NOT EXPECTED THIS MORNING, A FEW STORMS MAY BECOME STRONG
TO MARGINALLY SEVERE. STORMS WILL LIKELY STILL BE ONGOING THIS
AFTERNOON AND MAY INTENSIFY AND EXPAND IN COVERAGE AS THE ATMOSPHERE
DESTABILIZES. CAPE VALUES ARE EXPECTED TO BE OVER 3,000 J/KG IN
AREAS THAT RECEIVE THE MOST SUNLIGHT. 0 TO 6 KM WIND SHEAR WILL BE
OVER 50 KNOTS AREAWIDE THIS AFTERNOON. HOWEVER, MID-LEVEL LAPSE
RATES MAY BE HINDERED THIS AFTERNOON BY CLOUD COVER AND ONGOING
CONVECTION. MODELS DIFFER ON PLACEMENT OF RAIN AND THUNDERSTORMS
THIS AFTERNOON THROUGH TONIGHT SO IT IS DIFFICULT TO PINPOINT WHERE
STORMS WILL BE AT A PARTICULAR TIME. IT DOES APPEAR AS THOUGH THE
NEBRASKA COUNTIES IN OUR FORECAST AREA WILL BE MORE LIKELY TO BE
IMPACTED BY THUNDERSTORMS THIS AFTERNOON THAN THE NORTH CENTRAL
KANSAS COUNTIES. THE VAST MAJORITY OF THE FORECAST AREA BY/AROUND 10
PM WILL LIKELY EITHER BE GETTING RAIN AND/OR STORMS. RAIN AND STORM
CHANCES AT 10 PM RANGE FROM AROUND 60% TO 90%. SOME MODELS INDICATE
ANOTHER CLUSTER/LINE OF STORMS MOVING IN FROM THE WEST INTO NORTH
CENTRAL KANSAS AND SOUTHERN NEBRASKA THIS EVENING. THE RAIN AND
STORMS ARE EXPECTED TO CONTINUE THROUGH MOST, IF NOT ALL, OF THE
OVERNIGHT HOURS. AN MCS MAY DEVELOP LATE THIS EVENING INTO THE
OVERNIGHT HOURS AND PUSH THROUGH THE AREA.
LARGE HAIL UP TO AROUND GOLF BALL SIZE, WIND GUSTS UP TO AROUND 70
MPH, ISOLATED TORNADOES, AND FLOODING WILL ALL BE POSSIBLE. THE WIND
AND FLOODING THREATS WILL INCREASE LATER THIS EVENING INTO TONIGHT.
MUCH OF THE FORECAST AREA IS IN A FLOOD WATCH FROM 7 PM THIS
EVENING TO 7 AM SUNDAY. TOTAL RAIN AMOUNTS TODAY THROUGH SUNDAY
ARE EXPECTED TO RANGE FROM 1 TO 5 INCHES ACROSS THE WHOLE AREA
WITH AMOUNTS OF 2 TO 5 INCHES IN THE FLOOD WATCH. RAIN WILL
CONTINUE MOVING EASTWARD SUNDAY MORNING WITH MORE SHOWERS AND
STORMS POSSIBLY MOVING INTO WESTERN PORTIONS OF THE AREA SUNDAY
AFTERNOON AND EVENING. SOME OF THESE STORMS ON SUNDAY HAVE THE
POTENTIAL TO BECOME STRONG TO MARGINALLY SEVERE WITH HAIL UP TO
QUARTER SIZE AND WIND GUSTS UP TO 60 MPH DEPENDING ON HOW
DESTABILIZED THE ATMOSPHERE BECOMES AFTER THE STORMS FROM TONIGHT.
HIGH TEMPERATURES BOTH TODAY AND SUNDAY ARE EXPECTED TO MOSTLY
BE IN THE 70S AND 80S. LOW TEMPERATURES TONIGHT WILL BE IN THE
50S AND 60S.
DISCUSSION
ISSUED AT 142 PM CDT FRI JUN 19 2026
THIS IS AN ACTIVE FORECAST, PRIMARILY WITHIN THE FIRST 2-3 DAYS.
ONGOING SCATTERED SHOWERS AND THUNDERSTORMS WERE NOT WELL
FORECAST, WITH SOME MODELS HINTING AT IT EARLY TODAY. HOWEVER,
AS THE DAY HAS EVOLVED, MODELS PERSIST WITH THIS ACTIVITY, BUT
EVEN WITH RADAR AS AN INITIAL CONDITION, HIGH-RES MODELS ARE
STRUGGLING WITH AREAL COVERAGE. CONFIDENCE IN THE NEXT 48 HOURS
HAS EVOLVED THROUGHOUT THE DAY TODAY, BUT THERE REMAINS
UNCERTAINTY IN HOW EACH ROUND OF CONVECTION WILL IMPACT THE
NEXT.
CURRENT EXPECTATIONS FOR THE EVOLUTION OF THE NEXT 48 HOURS.
ROUND 1:
ONGOING SCATTERED THUNDERSTORMS THIS AFTERNOON ARE EXPECTED TO
EVENTUALLY DIMINISH AND MOVE EAST SOUTHEAST TAPERING A BIT BY
THE EVENING HOURS FOR MUCH OF SOUTH CENTRAL NEBRASKA. THERE IS A
SIGNAL OF SOME OFF AND ON SCATTERED STORMS PERSISTING IN NORTH
CENTRAL KANSAS INTO THE EVENING AND EARLY OVERNIGHT HOURS. THE
BEST INSTABILITY REMAINS OFF TO THE WEST OF THE AREA. THIS
AFTERNOON, SEVERE THUNDERSTORMS ARE NOT EXPECTED. LATER TONIGHT,
SOME MARGINALLY SEVERE STORMS COULD DEVELOP WITH HAIL TO THE
SIZE OF QUARTERS.
LARGELY EXPECT A LULL IN MOST OF THE ACTIVITY DURING THE
OVERNIGHT HOURS.
ROUND 2:
THIS ROUND IS EXPECTED TO BEGIN JUST BEFORE SUNRISE ON SATURDAY
MORNING ALONG OR NEAR THE HIGHWAY 183 CORRIDOR. HIGH-RES
ENSEMBLES AND EVEN THE EC ENSEMBLE SUPPORT THIS MORNING
DEVELOPMENT. THIS ACTIVITY WILL HAVE SLIGHTLY MORE INSTABILITY
TO WORK WITH THAN ROUND 1 DID. WHILE WIDESPREAD SEVERE WEATHER
IS NOT EXPECTED, SOME OF THE STORMS COULD BE STRONG TO SEVERE.
THIS ACTIVITY WILL SLOWLY MOVE EASTWARDS THROUGH OUT THE DAY.
EXPECT A LULL IN ACTIVITY AFTER ROUND 2 PASSES IN THE AFTERNOON.
ROUND 3:
THIS ROUND IS EXPECTED TO DEVELOP IN THE HIGH PLAINS OF NEBRASKA
AND KANSAS AND TRACK EASTWARD AIDED BY AN UPPER DISTURBANCE.
THIS ACTIVITY CONTINUES TO HAVE THE BEST INGREDIENTS TO WORK
WITH FOR THE MOST PART, AND THE PRIMARY CONCERN FOR STRONG TO
SEVERE THUNDERSTORMS. THAT BEING SAID, THIS ROUND ALSO MAY BE
IMPACTED BY THE ROUNDS BEFORE IT, AND THAT BRINGS IN SOME
UNCERTAINTY. ROUND 2 MAY LIMIT SOME OF THE ABILITY FOR THE
ATMOSPHERE TO RECOVER ALONG AND NORTH OF I-80, AND THERE HAS
BEEN SUBTLE SHIFTS IN THE GUIDANCE THAT IS TRENDING THE PRIMARY
SEVERE THREAT ALONG AND SOUTH OF THE NEBRASKA/KANSAS STATELINE.
WITH ROUND 3, THE PRIMARY THREAT IS WIND AS A LINE OF STORMS
DEVELOPS TO OUR WEST ON THE HIGH PLAINS AND TRACKS EASTWARD INTO
THE EVENING AND OVERNIGHT HOURS. SEVERE WINDS UP TO 70 MPH ARE
POSSIBLE. HAIL UP TO GOLFBALL SIZE IS POSSIBLE, BUT THAT BEST
THREAT IS ALONG AND WEST OF HIGHWAY 183.
THIS THIRD ROUND HAS A LOT OF UPPER LEVEL SUPPORT, AND WHILE THE
WORST OF THE SEVERE ACTIVITY IS ALONG AND SOUTH OF THE STATE
LINE, SEVERE STORMS ARE POSSIBLE THROUGHOUT THE WHOLE AREA. IN
ADDITION TO THE STRONG STORMS, THE REPEATED ROUNDS OF RAIN WILL
INCREASE THE CHANCE FOR FLOODING. ROUND 3 DOESN'T LINGER LONG,
BUT VARIOUS MODELS AND ENSEMBLES, INDICATE THE POTENTIAL FOR 2-3
INCHES OF RAIN WITH SOME LOCALLY HIGHER AMOUNTS POSSIBLE. HAVE
JOINED NEIGHBORS AND ISSUED A FLOOD WATCH. DID NOT INITIALLY
INCLUDE VALLEY AND GREELEY COUNTIES, BUT COULD SEE THEM BEING
ADDED IN THE NEXT UPDATE.
SUNDAY:
ADDITIONAL THUNDERSTORMS ARE POSSIBLE SUNDAY, THESE COULD BE
STRONG TO SEVERE AS WELL, BUT HAVE FOCUSED PRIMARILY ON TODAY
AND SATURDAY FOR THIS FORECAST.
WORKWEEK:
THE REMAINDER OF THE FORECAST IS ACTIVE AS THE CENTRAL PLAINS
SITS UNDER ZONAL TO SLIGHTLY NORTHWESTERLY FLOW, ALLOWING EACH
WEAK DISTURBANCE TO IMPACT THE REGION. TEMPERATURES GENERALLY IN
THE 70S FOR THE WEEK, WHICH IS BELOW THE 80+ DEGREE NORMALS WE
USUALLY SEE IN THE SECOND HALF OF JUNE.
AVIATION /12Z TAFS THROUGH 12Z SUNDAY/
ISSUED AT 629 AM CDT SAT JUN 20 2026
FOR KGRI/KEAR AIRPORTS:
A FEW SHOWERS/THUNDERSTORMS HAVE DEVELOPED AMONGST A LOW-MID
LEVEL CLOUD LAYER ACROSS THE AREA THIS MORNING. THIS
THUNDERSTORM/CLOUD CLUSTER IS EXPECTED TO MOVE OUT OF THE AREA
SOMETIME IN THE AFTERNOON. HOWEVER, THE LOCATION/COVERAGE OF
THESE SHOWERS/THUNDERSTORMS THIS MORNING AND THEIR ESTIMATED
TIME OF ARRIVAL/DEPARTURE IS UNCERTAIN, HENCE THE TEMPO AND
PROB30 GROUPS.
ANOTHER CHANCE OF STRONG TO SEVERE THUNDERSTORMS IS POSSIBLE
THIS EVENING AS A THUNDERSTORM CLUSTER MOVES INTO THE AREA.
AGAIN, THIS THREAT WAS INCLUDED AS A PROB30 GROUP AS UNCERTAINTY
REMAINS IN THE LOCATION, SEVERITY, AND TIMING OF THESE STORMS.
SHOULD THESE THUNDERSTORMS IMPACT THE TERMINAL, PERIOD OF HAIL,
STRONG WINDS, AND IFR VISIBILITIES/CEILINGS MAY BE POSSIBLE.
