THE HEAT WAVE WILL CONTINUE WITH OUR REGION REMAINING UNDER THE
INFLUENCE OF AN UPPER LEVEL RIDGE. A HEAT ADVISORY REMAINS IN
EFFECT THROUGH SUNDAY AS HIGH TEMPERATURES CONTINUE TO REACH
NEAR RECORD TO RECORD READINGS IN THE MIDDLE 90S TO NEAR 100
DEGREES.
A WEAK BOUNDARY TO OUR NORTH IS EXPECTED TO SAG FAR ENOUGH
SOUTHWEST LATE TODAY AND TRIGGER ISOLATED SHOWERS AND
THUNDERSTORMS ACROSS NORTHWEST AND EASTERN PORTIONS OF THE PAH
FORECAST AREA (FA). THE BOUNDARY WILL RETREAT BACK NORTHEAST
LATE TONIGHT, BUT A STRAY SHOWER OF STORMS IS NOT OUT OF THE
QUESTION SATURDAY AFTERNOON IN PORTIONS OF SOUTHWEST INDIANA.
THE UPPER RIDGE WILL GRADUALLY BREAK DOWN OVER THE WEEKEND, AND
MODELS BRING A COLD FRONT SLOWLY THROUGH THE MIDDLE MISSISSIPPI
AND LOWER OHIO VALLEY LATE SUNDAY INTO MONDAY. WINDS WILL SHIFT
TO THE WEST THEN NORTH SUNDAY AFTERNOON INTO SUNDAY NIGHT.
CHANCES OF SHOWERS AND STORMS WILL SLOWLY SPREAD INTO NORTHERN
AND WESTERN PORTIONS OF THE PAH FA LATE SUNDAY NIGHT INTO MONDAY
MORNING, WITH CHANCES INCREASING AND SPREADING SOUTHEAST BY
MONDAY AFTERNOON. MONDAY AFTERNOON CHANCES WILL RANGE FROM
20-40% ACROSS WEST KENTUCKY, TO 40-60% CHANCES ACROSS THE REST
OF THE AREA, THEN 30-50% CHANCES WILL CONTINUE INTO MONDAY
EVENING. 20-40% CHANCES WILL TAPER OFF FROM NORTHWEST TO
SOUTHEAST LATE MONDAY NIGHT THROUGH TUESDAY.

FROM THE HEAT, WITH HIGHS MONDAY RANGING FROM THE UPPER 80S
NORTHWEST TO MIDDLE 90S SOUTHEAST, THEN TUESDAY FROM THE MIDDLE
70S NORTHWEST TO MIDDLE 80S SOUTHEAST. DRY CONDITIONS AND NEAR
