WEATHER SUMMARY
NATIONAL WEATHER SERVICE PADUCAH KY
443 AM CDT THU JUN 25 2015

WITH THE EXCEPTION OF A FEW THUNDERSTORMS ACROSS THE DELTA REGION
OF SOUTHEAST MISSOURI LATE WEDNESDAY AFTERNOON...SKIES REMAINED
RELATIVELY CLEAR ACROSS MOST OF THE QUAD STATE REGION ON
WEDNESDAY.

THE BENEFIT OF LIGHT NORTHEAST WINDS HELPED KEEP THE AIR A LITTLE
DRIER ACROSS THE QUAD STATE REGION. THE DRIER AIR IN TURN KEPT
HEAT INDEX VALUES DOWN OVER PARTS OF SOUTHERN ILLINOIS...SOUTHWEST
INDIANA AND PENNYRILE AREA OF WEST KENTUCKY...EAST OF THE LAND
BETWEEN THE LAKES. HEAT INDEX VALUES DID...HOWEVER...REACH INTO
THE 100 TO 104 DEGREE RANGE OVER PARTS OF SOUTHEAST MISSOURI
WEDNESDAY AFTERNOON.

HIGHS ON WEDNESDAY RANGED FROM 86 DEGREES IN OWENSBORO KENTUCKY TO
93 DEGREES IN POPLAR BLUFF MISSOURI. DESPITE THE HEAT...POPLAR
BLUFF BENEFITED FROM ISOLATED THUNDERSTORMS AS THE AFTERNOON
PROGRESSED.

FOR TODAY AND FRIDAY...A COMPLEX INTERACTION OF SMALL AND LARGE
SCALE WEATHER SYSTEMS WILL BRING SHOWERS AND THUNDERSTORMS TO THE
QUAD STATE REGION.

INITIALLY...LINGERING THUNDERSTORMS THAT OCCURRED OVERNIGHT IN
PARTS OF IOWA...NORTHEAST MISSOURI AND CENTRAL ILLINOIS WILL PUSH
INTO PARTS OF THE INTERSTATE 64 CORRIDOR TODAY. THESE
THUNDERSTORMS WILL REDEVELOP ALONG AN APPROACHING COLD FRONT
TONIGHT INTO EARLY FRIDAY.

A STRONG UPPER LEVEL DISTURBANCE WILL MOVE INTO THE MIDWEST EARLY
FRIDAY...SHIFTING THE FRONTAL BOUNDARY SLIGHTLY NORTHWARD ACROSS
THE QUAD STATE AREA. THIS WILL SHARPLY INCREASE THE CHANCES FOR
RAIN DURING THE DAY...BEFORE THE COLD FRONT COMPLETELY PUSHES
THROUGH THE REGION.

GIVEN THE ENERGY ASSOCIATED WITH THESE WEATHER SYSTEMS...THE
POTENTIAL FOR SEVERE WEATHER AND HEAVY RAINFALL WILL INCREASE AS
WELL.

THE CHANGE IN TEMPERATURES WILL BE DRAMATIC TODAY THROUGH
SATURDAY. HIGHS WILL BE IN THE LOWER TO MIDDLE 90S TODAY...MIDDLE
TO UPPER 80S ON FRIDAY...WITH UPPER 70S TO LOWER 80S POSSIBLE ON
SATURDAY BEHIND THE COLD FRONT. LOWS WILL MOVE FROM THE 70S INTO
THE 60S BY SATURDAY MORNING.

HEAT INDEX VALUES OF 100 TO 105 DEGREES WILL BE POSSIBLE LATER
TODAY ALONG AND AHEAD OF A COLD FRONT.

THE AREA WILL BE DRY AND COOLER ON SUNDAY...BUT WARMER WEATHER AND
CHANCES FOR RAIN WILL RETURN AGAIN NEXT WEEK.
