DISCUSSION
ISSUED AT 1255 AM CDT MON JUL 14 2025
AN UPPER LEVEL TROUGH HAS ESSENTIALLY STALLED OVER NORTHWESTERN
MO/IL LEADING TO A LITTLE BIT OF SUSTAINED LARGE SCALE ASCENT
OVER THE AREA TONIGHT. THIS IS WORKING WITH OUR SOUPY AIRMASS TO
KEEP SHOWERS AND A FEW THUNDERSTORMS GOING IN TWO CLUSTERS, ONE
NORTH OF CAPE GIRARDEAU AND SOUTH OF CARBONDALE, AND THE OTHER
IN NORTHEASTERN ARKANSAS. BUOYANCY IS VERY DIURNALLY LIMITED SO
SEVERE WEATHER RISK APPEARS NEGLIGIBLE BUT THE SLOW STORM
MOTION, PARTICULARLY IN CAPE COUNTY AND VICINITY IS COUPLING
WITH 2.1" PWATS TO LEAD TO A RESPECTABLE FLASH FLOOD THREAT FOR
THE NEXT FEW HOURS.
THE UPPER PATTERN REMAINS VERY SIMILAR WITH THE AREAS OF
ACCELERATION/DECELERATION BECOMING LESS OBVIOUS THAN THEY ARE
CURRENTLY THROUGH THE NEXT 72 HOURS. DEWPOINTS STAY IN THE MID
70S THROUGH THE WEEK SO ISOLATED TO SCATTERED AFTERNOON SHOWERS
AND THUNDERSTORMS SHOULD CONTINUE TO BE EXPECTED. A SMALL SEVERE
RISK FOR AFTERNOON DOWNBURSTS AND A FLASH FLOOD THREAT WILL
EXIST WITH THIS ACTIVITY ALTHOUGH ITS MORE SCATTERED NATURE MAY
LIMIT IMPACTS.
BY THURSDAY INTO FRIDAY A STRONGER MORE ZONAL JET PATTERN IS
INDICATED BY GFS/ECMWF GUIDANCE WITH A LITTLE STRONGER SHORTWAVE
ON THURSDAY. THIS FEATURE THOUGH SEEMS TO BE TRENDING SLIGHTLY
FURTHER NORTH. 500MB HEIGHTS INCREASE TO AROUND 596DM WITH
DEWPOINTS IN THE UPPER 70S. IN GENERAL WE STILL LOOK FAIRLY
LIKELY TO HAVE AFTERNOON SHOWERS AND STORMS BUT WITH HEIGHTS AND
DEWPOINTS LIKE THAT IT WON'T TAKE MUCH TO BE INTO HEAT ADVISORY
CRITERIA BY THURSDAY INTO SATURDAY, ESPECIALLY WITH THE GENERAL
TREND OF THE SHORTWAVE TROUGH BEING A BIT FURTHER NORTH AND
LESSER PRECIP/CLOUD COVERAGE. THE PATTERN BASICALLY HOLDS SHAPE
THROUGH THE END OF THE CURRENT FORECAST PERIOD WITH AFTERNOON
SHOWERS AND STORMS AND OPPRESSIVE HUMIDITY.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
ISSUED AT 605 AM CDT MON JUL 14 2025
RESIDUAL PATCHY FOG AND LOW STRATUS SHOULD MIX OUT QUICKLY THIS
MORNING. CONVECTION WILL BE AN ISSUE AGAIN AFTER ABOUT 17Z OR SO
BUT COVERAGE SHOULD BE MORE LIMITED THAN IT WAS OVER THE
WEEKEND. BRIEF IFR VISIBILITY AND GUSTY WINDS SHOULD BE EXPECTED
AROUND THUNDERSTORMS. WINDS SHOULD REMAIN RELATIVELY LIGHT
THROUGH THE DAY TODAY AND EVEN LIGHTER TONIGHT.
