KEY MESSAGES
- THE HOTTEST STRETCH OF THE SEASON CONTINUES WITH HIGH

THURSDAY, FOLLOWED BY SOME RELIEF ON FRIDAY.

NIGHT AND FRIDAY AHEAD OF A COLD FRONT. SOME OF THE STORMS
COULD BE STRONG TO SEVERE WITH DAMAGING WINDS AND BRIEF HEAVY
RAIN AS THE MAIN THREATS.

THUNDERSTORM CHANCES RETURNING THROUGH MONDAY OR TUESDAY.
AREAS OF HEAVY RAINFALL/FLOODING APPEAR POSSIBLE IN THE
ADVERTISED PATTERN.
DISCUSSION
ISSUED AT 1227 AM CDT WED JUN 10 2026
THE UPPER LEVEL LOW THAT HAS BEEN KEEPING RAINY AND STORM
CONDITIONS IN PLACE HAS DEPARTED TO THE EAST. 500MB HEIGHTS ARE
AROUND 590 DM. BROAD TROUGHING OVER THE WESTERN US IS EATING
AWAY AT THOSE HEIGHTS A LITTLE AND SLIGHTLY DRIER AIR IS MOVING
INTO THE 700-850MB RANGE PER OBSERVED 00Z SOUNDINGS. SURFACE
DEWPOINTS ARE STILL IN THE LOW TO MID 70S HOWEVER. IT IS GOING
TO BE HOT AND HUMID, HEAT INDEX VALUES 100 TO 105 DEGREES ARE
ANTICIPATED AND IF THERE IS EVEN A LITTLE OVERACHIEVEMENT WE
WILL EXCEED HEAT ADVISORY CRITERIA. IT DOES LOOK LIKE HOWEVER
DEEP VERTICAL MIXING SHOULD MIX OUR DEWPOINTS DOWN ENOUGH TO
STAY BELOW 105, BUT IT WILL BE CLOSE. CONDITIONS APPEAR FAIRLY
SIMILAR ON THURSDAY. CLOUD COVER LOOKS LIKE IT COULD BE A
LITTLE MORE OF A FACTOR IN THE AFTERNOON AS A STORM SYSTEM
APPROACHES FROM THE NORTHWEST. IN THE LARGER COLLAB PICTURE WE
ARE A LITTLE SHORT OF HEAT ADVISORY CRITERIA ALTHOUGH THE
IMPACTS MAY STILL BE NOTABLE SO WILL CONTINUE MESSAGING AND
IMPROMPTU ADVISORIES MAY STILL BE NEEDED DEPENDING ON OBS
TRENDS.
A SHORTWAVE TROUGH ADVANCES TOWARDS THE REGION THURSDAY NIGHT
WITH A COLD FRONT MOVING ALONG WITH IT. THE UPPER LEVEL FORCING
IS PRETTY NEUTRAL TIL THE FRONT ARRIVES BUT THERE DOES APPEAR TO
BE A WINDOW OF OVERLAP OF SOME FAVORABLE SHEAR/INSTABILITY TO
SUPPORT A SEVERE WEATHER THREAT IN THE LATE OVERNIGHT MOVING IN
FROM THE NORTHWEST. INSTABILITY DOES APPEAR TO BE WANING AS ANY
CONVECTION APPROACHES THOUGH GIVEN THE LOCATION OF JET-LEVEL
ASCENT AND DIURNAL COOLING.
AFTER A BRIEF HUMIDITY RESPITE BEHIND THIS FRONT THE SOUP COMES
BACK BY SATURDAY NIGHT. A RIPPLY ZONAL SUBTROPICAL/POLAR JET
PHASE SITS TO OUR NORTH WITH A FEW WEAK SHORTWAVES STIRRING
THINGS UP. BLENDING THE GFS/ECMWF OVERALL SOLUTION SHOWER AND
STORM CHANCES LOOK TO SPARK UP AND PERSIST AGAIN THROUGH MONDAY
NIGHT OR TUESDAY. THE SOLUTIONS FOR NOW POINT TOWARDS DEEP RICH
MOISTURE AND MODEST INSTABILITY SUPPORTIVE OF A HEAVY RAIN
PATTERN RIDING ALONG SOUTH OF AN WEST TO EAST FRONT. AS THE
EVENT NEARS IT IS PROBABLY REASONABLE TO EXPECT WINDOW FOR FLASH
FLOODING (AND POSSIBLY ISOLATED SEVERE) DURING THAT PERIOD.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1025 PM CDT TUE JUN 9 2026
A FEW THUNDERSTORMS MAY APPROACH THE EVV/OWB TERMINALS LATER
THIS EVENING AND OVERNIGHT, BUT THE PROBABILITY HAS DROPPED OFF
EVEN FURTHER THAN THE LAST UPDATE. REMOVED THE PROB30 AS A
RESULT OF THE LATEST TRENDS. ALL TAF SITES ARE EXPECTED TO
REMAIN DRY THROUGH THIS ISSUANCE. GOOD FLYING CONDITIONS ARE
EXPECTED THROUGH THIS ISSUANCE.
