Synopsis...

HIGH PRESSURE OVER THE GREAT LAKES TO WESTERN KENTUCKY CONTINUED TO 
PRODUCE DRY CONDITIONS AND ALMOST CLOUDLESS SKIES THIS AFTERNOON. 
THE ABUNDANT SUNSHINE...EVEN THOUGH NORTHERLY WINDS 
PREVAILED...ALLOWED TEMPERATURES TO CLIMB TO AFTERNOON READINGS FROM 
THE UPPER 70S ALONG THE LAKE ERIE SOUTH SHORE...TO THE MIDDLE TO 
UPPER 80S ACROSS THE STATE.

AN UPPER LEVEL DISTURBANCE...PRODUCING SHOWERS AND THUNDERSTORMS 
OVER LAKE MICHIGAN...WAS DROPPING TO THE SOUTH AT THE END OF 
THE AFTERNOON...AND HAS SPREAD CLOUDS OVER THE WESTERN REGION OF THE 
STATE. THERE IS A SLIGHT CHANCE OF A SHOWER OR AN ISOLATED 
THUNDERSTORM ALONG THE OHIO AND INDIANA BORDERS WITH THIS 
DISTURBANCE OVERNIGHT. BUT FOR MOST OF THE STATE SKIES WILL BE 
MOSTLY CLEAR. TEMPERATURES OVERNIGHT WILL FALL A FEW MORE DEGREES 
BOTTOMING OUT IN THE MIDDLE 50S IN THE SOUTHEAST TO THE MIDDLE 60S 
IN THE WEST.

THE HIGH PRESSURE RIDGE WILL DRIFT SLOWLY TO THE EAST THROUGH 
FRIDAY....WITH THE SURFACE HIGH OFF TO THE EAST OF THE STATE. THIS 
WILL ALLOW A WARM FRONT TO LIFT TO THE NORTHEAST THROUGH THE STATE. 
THIS WILL ALSO PRODUCE SOUTHERLY WINDS...BRINGING HOT AND HUMID 
CONDITIONS THAT WILL BE FAVORABLE FOR A CHANCE OF AFTERNOON AND 
EVENING SCATTERED SHOWERS AND THUNDERSTORMS. THE AFTERNOON 
TEMPERATURES WILL CLIMB TO READINGS IN THE MIDDLE 80S.

ON FRIDAY EVENING THROUGH SATURDAY MORNING...A SCATTERED SHOWER OR  
THUNDERSTORM MAY LINGER IN THE STATE...BUT WILL SLOWLY DISSIPATE 
LATE IN THE EVENING. OVERNIGHT LOWS WILL TAIL OFF TO READINGS 
RANGING FROM THE MIDDLE 60S IN THE SOUTHEAST...TO THE LOWER 70S IN 
THE NORTHWEST.

EXPECT AN INCREASING CHANCE FOR SHOWERS AND THUNDERSTORMS SATURDAY 
AND SUNDAY...AS A WEAK COLD FRONT DROPS TO THE SOUTHEAST AND  
THROUGH THE STATE. HIGH PRESSURE BUILDS BACK ACROSS THE STATE SUNDAY 
NIGHT WITH THE COLD FRONT STALLING TO THE SOUTH OF THE OHIO VALLEY. 
THE HIGH TEMPERATURES WILL REACH THE UPPER 80S TO THE LOWER 90S 
SATURDAY AND SUNDAY...THEN LEVEL OUT IN THE MIDDLE TO UPPER 80S ON 
MONDAY AND TUESDAY.            
 
THE OHIO WEATHER STORY WILL BE DISCONTINUED ON JULY 1ST. QUESTIONS 
SHOULD BE DIRECTED TO GARY GARNET (GARY.GARNET@NOAA.GOV OR
