ISSUED AT 131 PM CDT SUN JUL 6 2025
CONVECTIVE INITIATION BEGAN LATE THIS MORNING WITH THE CU FIELD
BECOMING INCREASINGLY AGITATED THIS AFTERNOON. A COLD FRONT WAS
DRAPED ACROSS CENTRAL MISSOURI, WITH INCREASING MOISTURE
CONVERGENCE TO THE SOUTH OF THE BOUNDARY. WHILE MOST IF NOT ALL
ACTIVITY IS EXPECTED TO REMAIN SUB-SEVERE, RAP MESOANALYSIS
DEPICTS MUCAPE VALUES AROUND 2500 J/KG, 0-3 KM THETA-E
DIFFERENCES OF 25 DEG C, AND FAIRLY STEEP LOW-LEVEL LAPSE RATES,
WHICH MAY SUPPORT LOCALLY STRONG WIND GUSTS UP TO 50-60 MPH.
THIS POTENTIAL IS SUPPORTED BY THE OZARKS PULSE SEVERE
THUNDERSTORM INDEX. INTENSITY WILL DIMINISH AFTER 10 PM, THOUGH
A FEW CAMS LINGER SHOWERS AHEAD OF THE STALLED FRONT, SO WE HAVE
MAINTAINED SOME LOW-END POPS (20-40%) ACROSS SOUTHERN MISSOURI
OVERNIGHT.
GIVEN THE HIGH MOISTURE CONTENT AND SLOW STORM MOTION, WE WILL
HAVE TO MONITOR FOR LOCALLY HEAVY RAINFALL. IN FACT, THE 12Z
HREF LPMM SUGGESTS LOCALIZED AMOUNTS UP TO 3-4 INCHES. MOST
LOCATIONS WILL SEE LESS THAN THESE AMOUNTS, HOWEVER, SO
WIDESPREAD FLOODING IS NOT EXPECTED.
LONG TERM /MONDAY THROUGH SUNDAY/
ISSUED AT 131 PM CDT SUN JUL 6 2025
MONDAY-SATURDAY:
LITTLE CHANGE TO THE ENSEMBLE SUITE WAS NOTED FOR THE LONG-TERM
FORECAST; THAT IS, A QUASI-ZONAL FLOW PATTERN ALOFT WITH
TRANSIENT EMBEDDED SHORTWAVE DISTURBANCES WILL ALLOW FOR
INTERMITTENT RAIN CHANCES THROUGHOUT THE WEEK. CURRENTLY, THE
LOWEST RAIN CHANCES (15-30%) ARE ON THURSDAY. NBM PERCENTILES
SUPPORT CLIMATOLOGICALLY AVERAGE TEMPERATURES EACH DAY, WITH
HIGHS IN THE UPPER 80S TO AROUND 90 DEGREES.
AVIATION /18Z TAFS THROUGH 18Z MONDAY/
ISSUED AT 1218 PM CDT SUN JUL 6 2025
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO INITIATE
ACROSS THE REGION THIS AFTERNOON AND LAST THROUGH THE EVENING
HOURS. THE STRONGEST STORMS WILL BE CAPABLE OF REDUCING
VISIBILITIES DOWN TO 1 SM OR LESS DUE TO HEAVY RAIN AND WIND
GUSTS UP TO 40-45 KT. WHILE MOST CONVECTION LOOKS TO WIND DOWN
AFTER 03Z, A FEW STRAY SHOWERS MAY LINGER OVERNIGHT. SCATTERED
STORMS LOOK TO REFIRE AGAIN TOMORROW AFTERNOON.
