KEY MESSAGE 1...
SCATTERED SHOWERS WITH A FEW ISOLATED THUNDERSTORMS ARE
DEVELOPING AND WILL REMAIN POSSIBLE THROUGH THE REMAINDER OF
THIS AFTERNOON AND EARLY EVENING AS A SHORTWAVE ALOFT PUSHES
THROUGH THE REGION. HIGHEST COVERAGE FOR SHOWERS AND STORMS
WILL OCCUR ALONG AND EAST OF THE I-71 CORRIDOR WHERE THE BEST
INSTABILITY, ALBEIT FAIRLY WEAK AT 400-700 J/KG, EXISTS. LOCALLY
STRONGER BUT SUB- SEVERE THUNDERSTORMS MAY BE CAPABLE OF
PRODUCING ISOLATED WIND GUSTS OF 30-40 MPH AND SMALL HAIL.
KEY MESSAGE 2...
WIDESPREAD RAINFALL WILL OVERSPREAD THE OHIO VALLEY SUNDAY NIGHT
THROUGH MONDAY AS A SHORTWAVE ALOFT MOVES ACROSS THE REGION. AT THE
SURFACE, THE CENTER OF THE LOW PRESSURE IS EXPECTED TO TRACK DUE
EAST ACROSS NORTHERN OHIO ON MONDAY. THIS SYSTEM WILL BE MOISTURE
RICH AS PWAT VALUES WILL RANGE BETWEEN 1.25-1.75 INCHES, WHICH ARE
ABOVE THE 90TH PERCENTILE FOR MID/LATE JUNE. OVERALL QPF AMOUNTS
CONTINUE TO DECREASE SLIGHTLY WITH CURRENT STORM TOTAL RAINFALL
AMOUNTS RANGING BETWEEN 0.75-1.25 INCHES. SLIGHTLY HIGHER AMOUNTS OF
1.25-1.50 INCHES ARE POSSIBLE NEAR THE I-75 CORRIDOR AND ALONG THE
LAKESHORE. SOME EMBEDDED THUNDERSTORMS WILL BE POSSIBLE MONDAY
MORNING, THOUGH THE BEST INSTABILITY REMAINS SOUTH OF THE FORECAST
AREA. LOCALIZED FLOODING MAY BE POSSIBLE IN ANY CONVECTION AND/OR
SHOWERS/STORMS THAT TRAIN OVER THE SAME AREA. THE MAJORITY OF THE
FORECAST AREA REMAINS IN A MARGINAL RISK (LEVEL 1 OF 4) FOR
EXCESSIVE RAINFALL WITH A SLIGHT RISK (LEVEL 2 OF 4) FOR THE WESTERN
THIRD OF THE FORECAST AREA.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
HIGH PRESSURE WILL BUILD INTO THE REGION THIS EVENING INTO THE
OVERNIGHT AND ALLOW FOR VFR CONDITIONS WITH MOSTLY CLEAR
CONDITIONS AND LIGHT WEST FLOW. SOME MID-LEVEL CEILINGS WILL BE
IN AND OUT OF THE KERI TERMINAL BUT SHOULD REMAIN VFR. A LOW
PRESSURE SYSTEM WILL APPROACH FROM THE WEST ON SUNDAY AND A
MID-LEVEL CLOUD DECK WILL PUSH ACROSS THE ENTIRE REGION AHEAD OF
IT. THE FIRST BIT OF RAIN WILL REACH THE WESTERN TERMINALS OF
KTOL AND KFDY JUST BEFORE THE END OF THE TAF PERIOD BUT ANY
NON-VFR SHOULD BE LATER ON SUNDAY NIGHT. RAIN SHOULD ALSO REACH
KCLE IN THE 30-HOUR TAF BUT ANY NON-VFR WOULD BE LATER ON MONDAY
MORNING. WINDS WILL SHIFT AROUND TO THE EAST OR SOUTHEAST WITH
THE INCOMING RAIN TOWARD THE END OF THE FORECAST PERIOD.
OUTLOOK...NON-VFR LIKELY SUNDAY NIGHT INTO MONDAY WITH RAIN.
MARINE
A COLD FRONT IS SWEEPING ACROSS THE LAKE THROUGH THIS EVENING,
SHIFTING WINDS TO A WEST-NORTHWEST DIRECTION...GENERALLY 10-15KT
IN THE OHIO WATERS AND 10KT OR LESS TO THE EAST. THESE WINDS MAY
BRIEFLY PERK UP TO 15 TO NEARLY 20KT LATE THIS AFTERNOON INTO
THIS EVENING IN PARTS OF THE WESTERN AND CENTRAL BASIN BEFORE
SHIFTING MORE NORTHWESTERLY AND GRADUALLY DIMINISHING OVERNIGHT
TONIGHT INTO EARLY SUNDAY. WAVES OF 1 TO 3 FEET WILL GENERALLY
HANDLE THINGS THROUGH TONIGHT, WITH THE GREATEST CHANCE FOR SOME
3 FOOTERS IN THE CENTRAL BASIN THIS EVENING. WINDS GRADUALLY
FLIP AROUND TO THE SOUTH ON SUNDAY, TO THE EAST-NORTHEAST SUNDAY
NIGHT, AND MORE NORTHEAST TO NORTH ON SUNDAY AS WEAK LOW
PRESSURE TRACKS THROUGH THE NORTHERN OHIO VALLEY. WINDS WILL
BECOME ELEVATED 15-25KT SUNDAY NIGHT INTO MONDAY, AND WITH THE E
TO N DIRECTION WE'LL LIKELY NEED SMALL CRAFT ADVISORIES AND
BEACH HAZARDS STATEMENTS FOR A NUMBER OF OUR NEARSHORE/COASTAL
ZONES. CALMER CONDITIONS RETURN BY TUESDAY BEHIND THIS SYSTEM.
