DISCUSSION

A RATHER MESSY DAY ALL AROUND WITH SHOWERS AND THUNDERSTORMS
MOVING THROUGH THE FORECAST AREA THROUGH THE ENTIRE DAY. THIS
HAS LIMITED HEATING FOR THE DAY AS WELL AS SHIFTED THE TIMING
OF THE POTENTIAL THUNDERSTORM ACTIVITY TO LATER OVERNIGHT INTO
MONDAY MORNING TIME PERIOD.
THUNDERSTORM ACTIVITY INITIALLY INITIATED ALONG THE LOW LEVEL
JET EARLY THIS MORNING WHICH MAJORITY OF THE STORMS WERE SUB-
SEVERE BUT BRINGING BRIEF HEAVY RAINFALL ACROSS DONIPHAN COUNTY
AND THEN ADDITIONAL STORMS PRODUCED HEAVY RAINFALL OVER
LEAVENWORTH. A VIGOROUS CONVECTIVE SYSTEM MOVED SOUTHWARD FROM
IA/MO INTO NORTH WESTERN MO AND NORTHEAST KS, IN WHICH THE NEW
CONVECTIVE STORMS INITIATED ALONG THE THE OUTFLOW BOUNDARIES
FROM THOSE STORMS. SO WE HAD SEVERAL ROUNDS OF PRECIPITATION,
ESPECIALLY WITHIN THE KC METRO AREA AND LEAVENWORTH COUNTY. ONE
OF THE STORMS THAT DEVELOPED AND MOVED EAST WAS A STRONGER STORM
THAT MOVED FROM TOPEKA WHICH BROUGHT ANOTHER ROUND OF
PRECIPITATION TO THE KC METRO AREA ALONG WITH SOME WIND GUSTS
OF 50 TO 55 MPH. AS IT MOVED EASTWARD THE CONVECTION THAT HAD
THE GREATEST ENVIRONMENT WITH MIAMI, LINN, BATES AND HENRY
COUNTIES HAD MORE HEATING POTENTIAL WITH THE LACK OF CLOUD COVER
WHICH ALLOWED STRONGER STORMS FROM 1-3PM, BUT ALSO PRODUCED
HEAVY RAIN 2-3 INCHES OF RAINFALL TO WEST CENTRAL MO.
NOW FOR THE ADDITIONAL MESSY PART, IS THAT CURRENT CAMS ARE A
BIT ALL OVER THE PLACE IN TERMS OF THUNDERSTORM ACTIVITY. THERE
IS ANTICIPATED TO ADDITIONAL THUNDERSTORM ACTIVITY TO DEVELOP IN
KS WITH AN EXPECTED MCS AND MOVE INTO MO SO THE SEVERE
POTENTIAL AND HEAVY RAINFALL FROM THE STORMS IN THE LATE
OVERNIGHT INTO EARLY MORNING HOURS ON MONDAY. THE HARDER PART
FOR EXAMPLE SUCH AS THE HRRR MODEL ALSO CHANGES LOCATION AS WELL
AS THE TIMING FURTHER LATER. WHAT CONFIDENCE DO HAVE IS THAT
THERE A SEVERE POTENTIAL THAT SHIFTED LATER, SO 3AM TO 10AM WITH
THE MAIN THREATS BEING DAMAGING WINDS AND WITH THE WARMER AND
MOIST ENVIRONMENT CAN EASILY SEE HEAVY PRECIPITATION ACROSS AN
AREA (MAINLY WEST OF HIGHWAY 65) IN WHICH ALREADY HAD WIDESPREAD
RAINFALL OF 2-3 INCHES ALREADY. ADDITIONAL PRECIPITATION
AMOUNTS FOR THROUGH TOMORROW MORNING ARE THE 1 TO 2 INCHES.
THANKFULLY ONE OF THE GOOD THINGS IS THAT THE TEMPERATURES AND
HUMIDITY RELIEF THAT WILL OCCUR IN THE UPCOMING WORK WEEK AHEAD
THROUGH MID WEEK WITH HIGH TEMPERATURES IN THE MID TO UPPER 80S
AND LOW TEMPERATURES IN THE 60S. UNFORTUNATELY THE HEAT RETURNS
ON THURSDAY REACHING BACK INTO THE UPPER 80S INTO LOWER 90S.
HOWEVER THE WEATHER PATTERN IS RELATIVELY DRY OR LOW END CHANCE
OF PRECIPITATION 15-20%.
AVIATION /00Z TAFS THROUGH 00Z MONDAY/
ISSUED AT 614 PM CDT SUN JUN 29 2025
CLOUD SHIELD FROM THE MCS ACROSS SOUTHERN MISSOURI AT 00Z WILL
CONTINUE TO THIN AND SHIFT SOUTHEAST THROUGH THE EVENING. THERE
IS THE POTENTIAL FOR ISOLATED-SCATTERED STORMS TO DEVELOP AFTER
06Z ACROSS EASTERN KS ON THE NOSE OF A LOW LEVEL JET, BUT TRENDS
HAVE BEEN POSITIONING THIS ACTIVITY FURTHER SOUTH SO ONLY
MENTIONED PROB30 AT IXD TERMINAL. ADDITIONAL STORMS ARE MORE
LIKELY TOWARDS SUNRISE WHEN COLD FRONT IS EXPECTED TO MOVE
THROUG THE AREA. THERE IS A BIT MORE CONFIDENCE WITH THIS
ACTIVITY, SO LARGELY COVERED WITH TEMPOS IN THE 11-15Z TIME
FRAME. DRIER CONDITIONS BUILD INTO THE REGION TOMORROW BEHIND
THE FRONT.
