DISCUSSION
ISSUED AT 136 PM CDT SUN JUL 6 2025
WATCHING ISOLATED TO SCATTERED THUNDER DEVELOP ACROSS PARTS OF
SEMO/SOUTHERN ILLINOIS AND SOUTHWEST INDIANA. IN THE HOT AND
HUMID AIRMASS MLCAPES ARE ABOUT 2500 J/KG. SFC-700MB THETA-E
DIFFERENTIALS ARE ABOUT 25-30C WITH ESSENTIALLY NON-EXISTENT
SHEAR. PWAT VALUES ARE ABOUT 2.00 INCHES. THIS WILL RESULT IN
VERY SLOW MOVING CONVECTION WITH VERY EFFICIENT RAINFALL RATES
AND WITH THE SLOW MOVEMENT ISOLATED FLASH FLOODING IS POSSIBLE.
A FEW DAMAGING DOWNBURSTS ARE ALSO POSSIBLE THIS AFTERNOON.
WE THEN STAY EMBEDDED IN A RELATIVE WEAKNESS IN THE FLOW ALOFT
THROUGH WEDNESDAY. WITH SURFACE DEWPOINTS IN THE LOW 70S
AFTERNOON SHOWERS AND STORMS ARE PRETTY MUCH GUARANTEED THROUGH
THAT PERIOD. COVERAGE WILL BE LIMITED BY THE RELATIVELY LACK OF
FORCING BUT LOCALLY HEAVY RAIN AND A DOWNBURST OR TWO SEEM
POSSIBLE GIVEN THE PARAMETER SPACE.
A LITTLE BIT OF A COVERAGE DECREASE FOR THE LATTER HALF OF THE
WEEK, BRIEFLY, BEFORE AN ASPIRING COOLER-THAN-IT-WAS FRONT TRIES
TO WORK TOWARDS THE AREA ON SATURDAY. FROM THE LOOK OF THE
UPPER-LEVEL PATTERN PROVIDED BY THE GFS/ECMWF I WOULDN'T GET MY
HOPES UP TOO HIGH THE FRONT MAKES IT THROUGH BUT IT DOES SEEM TO
BE STRONG ENOUGH TO RESULT IN AN INCREASE IN COVERAGE OF SHOWERS
AND STORMS. HEAT INDEX VALUES REMAIN HOT BUT SEASONABLE AND
BELOW ADVISORY LEVELS BASED ON THE CURRENT FORECAST.
AVIATION /06Z TAFS THROUGH 06Z TUESDAY/
