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 216-265-2382 EXT 223)
