ISSUED AT 200 AM CDT FRI JUL 4 2025
THROUGH TONIGHT: UPPER-LEVEL RIDGING AND SURFACE HIGH PRESSURE
ARE PRESENT ACROSS THE REGION, WITH SUBTLE WEAK ENERGY UNDERCUTTING
THE FLOW. THE PRESENCE OF THIS WEAK FORCING MAY SUPPORT A FEW
ISOLATED SHOWERS OR THUNDERSTORMS LATER TODAY. OTHERWISE,
EXPECT SOME MORNING FOG OVER PORTIONS OF THE LAKES AND RIVERS,
QUICKLY BURNING OFF AFTER SUNRISE. A MUGGY DAY EXPECTED FOR
INDEPENDENCE DAY, WITH HIGHS IN THE UPPER 80S TO AROUND 90 IN
ADDITION TO DEWPOINTS IN THE UPPER 60S TO LOWER 70S. THIS WILL
SUPPORT MAXIMUM AFTERNOON HEAT INDEX VALUES IN THE MIDDLE TO
UPPER 90S. A SCATTERED CUMULUS FIELD DEVELOPS THROUGH THE LATE
MORNING AND AFTERNOON, WITH A HANDFUL OF CAMS HIGHLIGHTING
ISOLATED SHOWERS AND A STRAY THUNDERSTORM BY LATE AFTERNOON INTO
THE EVENING. THIS ACTIVITY WOULD PRIMARILY BE DRIVEN BY DAYTIME
HEATING, AND PULSE LIKE IN NATURE. HOWEVER, THE PRESENCE OF
LARGE SCALE SUBSIDENCE AND CAPPING SHOULD LIMIT OVERALL COVERAGE
AND CHANCES. THE HIGHEST CHANCES (10-30%) ARE FOCUSED ALONG AND
WEST OF HIGHWAY 65, WITH THE TIMING BETWEEN 4 TO 10 PM. HEAVY
DOWNPOURS WOULD ACCOMPANY ANY OF THE ACTIVITY THAT DEVELOPS.

NEAR 90 CAN BE EXPECTED AREAWIDE.
SUNDAY-MONDAY: AS WE PROGRESS INTO THE LATER PART OF THE WEEKEND
AND EARLY NEXT WEEK, A SUBTLE BREAK DOWN IN THE RIDGE OCCURS
ACROSS THE REGION. THIS WILL SUPPORT A ZONAL TO NORTHWEST FLOW
PATTERN DEVELOPING, WITH A SERIES OF SHORTWAVES PROGGED TO
TRANSLATE THROUGH THE FLOW. THIS INTRODUCES A BIT HIGHER RAIN
CHANCES WITH A FRONTAL BOUNDARY SETTLING INTO OR NEAR THE AREA.
RAIN CHANCES ARE UPWARDS OF 30-60% ON SUNDAY AND MONDAY. THERE
REMAINS SOME UNCERTAINTY ON THE EXACT EXTENT OF COVERAGE AS
SLIGHT DIFFERENCES IN THE TIMING/LOCATION/INTENSITY OF FEATURES
COULD IMPACT THE FORECAST. NONETHELESS, WILL CONTINUE TO
ADVERTISE THE HIGHEST CHANCES DURING THE AFTERNOON AND EVENING
HOURS EACH DAY. THE ENVIRONMENT WILL BE FAVORABLE FOR LOCALIZED
HEAVY RAINFALL GIVEN THE HIGH MOISTURE CONTENT IN THIS AIRMASS
REGIME, WITH PWATS AROUND 1.8 TO 2.0 INCHES. HIGH TEMPERATURES
REMAIN AROUND NORMAL FOR EARLY JULY, IN THE MIDDLE TO UPPER 80S
INTO EARLY NEXT WEEK.
TUESDAY-THURSDAY: ADDITIONAL RAIN CHANCES (20-50%) PERSIST INTO
THE MIDDLE OF NEXT WEEK. THIS SUPPORTS THE SIGNAL FOR ABOVE
NORMAL PRECIPITATION PERSISTING INTO MID-JULY. HOWEVER, THERE IS
NO GIVEN DAY AT THIS TIME THAT APPEARS TO BE A COMPLETE WASHOUT.
STAY UPDATED ON THE FORECAST FOR ADDITIONAL DETAILS AS THEY
BECOME MORE CLEAR.
