CONVECTION FROM THIS MORNING HAS LEFT AN OUTFLOW BOUNDARY DRAPED
ACROSS THE AREA. MEANWHILE, ELEVATED CONVECTION IS ALREADY
ONGOING NEAR LBF AND ADDITIONAL CUMULUS IS DEVELOPING NEAR AND
ALONG THE REMNANT OUTFLOW. NEAR-TERM CAMS CAME INTO AGREEMENT
THIS MORNING THAT THE PRIMARY AREA OF REDEVELOPMENT WILL BE IN
WESTERN PORTIONS OF THE AREA (POSSIBLY BETWEEN MCCOOK AND
HOLDREGE) IN THE 3-5PM TIMEFRAME. THE STRONGEST CONVECTION IS
THEN EXPECTED TO PUSH SOUTHEASTWARD THROUGH THE LATE AFTERNOON
AND EVENING ALONG THE AXIS OF GREATEST INSTABILITY (3000+ J/KG
MLCAPE). DEEP-LAYER SHEAR IS ALSO QUITE STRONG, WITH EFFECTIVE
SHEAR POSSIBLY APPROACHING 50KTS AT TIMES. GIVEN THE EXPECTED
STORM MODE (MULTICELL CLUSTERS MERGING INTO LINE SEGMENTS), THE
PRIMARY SEVERE THREAT IS WIND, ALTHOUGH SEVERE HAIL IS ALSO
EXPECTED IN SOME AREAS. OUTPUT FROM THE CAMS WOULD INDICATE THAT
THUNDERSTORM WIND GUSTS OF 70-80 MPH ARE POSSIBLE. A TORNADO OR
TWO CANNOT BE RULED OUT, ALTHOUGH THE HIGHER THREAT APPEARS TO
BE TO OUR EAST AS THE QLCS BECOMES MORE ORGANIZED.
IN ADDITION TO THE SEVERE THREAT, CAMS ARE INDICATING THAT
THESE STORMS WILL BE VERY EFFICIENT RAINFALL PRODUCERS...WHICH
ISN'T SURPRISING WITH PWAT VALUES NEAR 1.7" PER MESOANALYSIS.
THE RRFS AND HRRR INDICATE POTENTIAL 2"/HR RAINFALL RATES AND
LOCALIZED TOTALS OF 3-4". AS SUCH, A FLOOD WATCH WAS ISSUED FOR
PORTIONS OF FAR SOUTHERN NEBRASKA AND NORTH CENTRAL KANSAS.
STORMS ARE EXPECTED TO EXIT THE AREA BY AROUND 10PM, BUT
ADDITIONAL CONVECTION FROM THE HIGH PLAINS MAY ROLL IN LATER
OVERNIGHT. GIVEN THE TIMING, THESE STORMS SHOULD NOT BE AS
INTENSE, BUT SOME STRONG TO SEVERE STORMS DO REMAIN POSSIBLE
INTO THE EARLY MORNING HOURS OF TUESDAY. THIS IS A RELATIVELY
NEW TREND, SO CONFIDENCE IN SPECIFICS REMAINS FAIRLY LOW.
TUESDAY IS EXPECTED TO BE THE WARMEST DAY OF THE YEAR SO FAR IN
MANY AREAS. AIDED BY A STRONG SOUTHERLY WIND (GUSTS 30-40 MPH),
HIGH TEMPERATURES IN THE 90S AND EVEN LOW 100S ARE EXPECTED.
HEAT INDEX VALUES MAY BRIEFLY APPROACH 105 DEGREES IN EASTERN
ZONES WHERE DEWPOINTS ARE HIGHER.
THE DAYTIME SHOULD REMAIN MOSTLY DRY, BUT SCATTERED
THUNDERSTORMS ARE EXPECTED TO MOVE WEST TO EAST ACROSS THE AREA
DURING THE LATE AFTERNOON AND EVENING HOURS. CONFIDENCE IN
COVERAGE REMAINS UNCERTAIN, BUT CONVECTIVE PARAMETERS (3-4000
J/KG MLCAPE AND 30KT 0-6KM SHEAR) WOULD BE FAVORABLE FOR A LEAST
A FEW SEVERE STORMS.
WEDNESDAY WILL TREND A BIT COOLER, AND THE MAIN THREAT AREA FOR
STORMS WILL SHIFT TO THE SOUTH/EAST. THAT SAID, A FEW STORMS
CANNOT BE TOTALLY RULED OUT WEDNESDAY EVENING INTO THE
OVERNIGHT.
WITH THE ACTIVE WEATHER IN THE NEAR-TERM, NOT MUCH TIME WAS
SPENT ON THE LONGER-RANGE FORECAST. AFTER A BREAK LATE THIS
WEEK, ENSEMBLES BRING T-STORM CHANCES BACK TO THE AREA OVER THE
WEEKEND AND INTO NEXT WEEK. MODELS ALSO FAVOR A GENERAL
"COOLING" TREND THIS WEEKEND INTO EARLY NEXT WEEK. SUNDAY AND
MONDAY COULD BE FEATURE HIGHS IN THE 70S...WHICH IS ABOUT 10
DEGREES BELOW NORMAL.
AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
ISSUED AT 556 PM CDT MON JUN 8 2026
FOR KGRI/KEAR AIRPORTS:
EARLY EVENING THUNDERSTORMS ARE EXPECTED TO REMAIN SOUTH OF THE
KGRI AND KEAR TERMINALS, AND WILL BE FOCUSED NEAR AND SOUTH OF
THE KANSAS-NEBRASKA STATE LINE. ADDITIONAL SHOWERS AND STORMS
DEVELOPING OVER NORTHEASTERN COLORADO, WESTERN NEBRASKA, AND
NORTHWESTERN KANSAS ARE FORECAST TO MOVE GENERALLY EASTWARD
OVERNIGHT. THERE IS SOME UNCERTAINTY IN HOW FAR NORTH AND EAST
THIS ACTIVITY WILL TRACK, ESPECIALLY WITH THE PRIMARY FRONTAL
BOUNDARY REMAINING NEAR THE KANSAS AND NEBRASKA BORDER AFTER
BEING REINFORCED BY THE EVENING STORMS IN THAT VICINITY. AS A
RESULT, ONLY A PROB30 IS INCLUDED IN THE 00Z TAF ISSUANCE FOR
KGRI AND KEAR FOR THE POTENTIAL OVERNIGHT ACTIVITY, FOCUSED IN
THE 05Z TO 10Z TIMEFRAME. THIS WILL BE RE-EVALUATED BASED ON
UPSTREAM TRENDS FOR LATER UPDATES.
THERE IS A MEDIUM TO HIGH CHANCE THAT LOW CEILINGS IN STRATUS
DEVELOP LATE TONIGHT AND CONTINUE THROUGH TUESDAY MORNING, AND A
LOW CHANCE THAT VISIBILITY REDUCTIONS IN FOG OCCUR, TOO. WE HAVE
INTRODUCED A PERIOD OF MVFR CEILINGS TUESDAY MORNING AT BOTH
KGRI AND KEAR TO ACCOUNT FOR THIS.
OTHERWISE, VFR CONDITIONS WILL GENERALLY PREVAIL OUTSIDE OF ANY
THUNDERSTORMS, AND AFTER STRATUS DISSIPATES BY ABOUT 18Z TUESDAY.
LIGHT WINDS ARE EXPECTED TONIGHT, BECOMING SOUTHERLY AND
INCREASING TUESDAY AFTERNOON. EXPECT GUSTS UP TO 25-30 KT AT
KGRI AND KEAR AFTER 21Z.
