DISCUSSION
ISSUED AT 248 AM CDT WED AUG 27 2025
PRECIPITATION WAS ABOUT TO ENTER SOUTHWEST KANSAS EARLY THIS MORNING
DOWNSTREAM OF A WEAK UPPER WAVE. SURFACE HIGH PRESSURE HAD
EXITED INTO EASTERN MISSOURI WITH SOUTHERLY LOW-LEVEL FLOW
RETURNING LOCALLY.
THIS INITIAL ROUND OF SHOWERS AND PERHAPS A FEW THUNDERSTORMS MOVES
INTO THE AREA THIS AFTERNOON WITH THE AID FROM SOME ISENTROPIC LIFT.
THIS SHOULD BE RATHER LIGHT, WITH A MORE INTENSE ROUND COMING THIS
EVENING INTO THURSDAY MORNING. MORE SHORTWAVE ENERGY EMERGES FROM
THE CENTRAL ROCKIES WITH MODEST LOW-LEVEL CONVERGENCE FROM CENTRAL
INTO SOUTHEAST KANSAS UNDER WHAT MAY BE A COUPLED JET STRUCTURE
ALOFT. PRECIPITABLE WATER VALUES LOOK TO BE AROUND 1.75 INCHES WITH
MODEST CAPE THOUGH THIS CAPE IS SPREAD THROUGHOUT THE COLUMN AND
SOME TRAINING OF THE STRONGER CONVECTION MAY OCCUR. OVERALL RATES
CONTINUE TO LOOK TO NOT BE VERY IMPRESSIVE FROM EVEN THE MOST ROBUST
CAMS WITH SPOTTY 10% CHANCES OF OVER AN INCH PER HOUR FROM THE 0Z
HREF AND LESS THAN A 10% CHANCE FOR 3 INCHES OVER 6 HOURS FROM THE
01Z NBM. THERE ALSO CONTINUES TO BE SOME SIGNAL FOR NEARLY ANY HEAVY
RAIN TO BE SOUTH OF THE LOCAL AREA. GIVEN DRY ANTECEDENT CONDITIONS,
THE CHANCE FOR FLASH FLOODING REMAIN LOW. THE MAIN IMPACT COULD BE
RISES ON SOME RIVERS AND CREEKS. A SOMEWHAT SLOWER ONSET TO THE
THICKER CLOUD SHOULD PUSH TODAY'S TEMPERATURES INTO THE 70S AREA-
WIDE. SOME CLEARING THURSDAY SHOULD AGAIN BRING AFTERNOON
TEMPERATURES INTO THE 70S THOUGH CONFIDENCE THE TIMING OF THE
CLEARING IS NOT HIGH. IF THE CLEARING IS MORE ROBUST, A FOG SCENARIO
COULD EASILY DEVELOP THURSDAY NIGHT INTO FRIDAY MORNING GIVEN LIGHT
WINDS AND POTENTIAL WET GROUND.
THE NEXT SEVERAL DAYS LOOK RATHER BENIGN OVERALL WITH MODEST
NORTHWEST FLOW ALOFT RETURNING. THIS SHOULD AID IN KEEPING SOMEWHAT
COOL TEMPERATURES IN PLACE WITH LITTLE CHANCE FOR PRECIPITATION.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
ISSUED AT 640 AM CDT WED AUG 27 2025
VFR CONDITIONS WILL CONTINUE THROUGH THE NEXT SEVERAL HOURS, BUT
STEADILY DECREASING CONDITIONS ARE LIKELY THROUGH THE END OF THE
FORECAST IN INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS AND
CEILINGS FALLING TO IFR, POTENTIALLY LOWER IN A WORSE CASE
SCENARIO. STILL APPEARS THE TERMINALS WILL BE ON THE NORTHERN
END OF PRECIPITATION THROUGH AROUND 06Z BUT SHOULD SEE MORE
COVERAGE BEYOND UNTIL AROUND 10Z.
TOP WATCHES/WARNINGS/ADVISORIES
NONE.
