Flash Flood Warning 6, NWS Cleveland, OH

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
717 AM EDT THU JUN 27 2013

.SYNOPSIS...
LOW PRESSURE WILL STALL OVER THE EASTERN LAKES THROUGH THE MIDDLE OF
NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE FIRST S/W MOVING THRU THE UPPER TROUGH DIGGING INTO THE LAKES
SHOULD MOVE EAST OF THE CWA BY MID AFTERNOON. THE THREAT FOR HEAVIER
RAIN SHOULD SETTLE DOWN WITH THE PASSAGE OF THE S/W SO THE FLOOD
WATCH THAT RUNS UNTIL 4 PM EDT MAY WORK OUT OKAY. MAY BE ABLE TO
CHOP OFF THE WESTERN ROW OR TWO OF COUNTIES BY NOON. FOR EARLY
MORNING UPDATE...MADE SOME ADJUSTMENTS TO ACCOUNT FOR PATCH OF
ENHANCED SHRA/TSRA OVER SENECA AND HURON CO'S. GRADUALLY BLEND THIS
PATCH INTO THE HIGHER POPS FURTHER EAST OVER THE NEXT FEW HOURS.

A LITTLE FOG PRESENT EARLY THIS MORNING...BUT NOT SEEING VSBYS A
MILE OR LESS SO WILL CONTINUE TO NOT MENTION.

THE WEST WILL SEE A BREAK FROM THE WIDESPREAD RAIN TODAY BUT WITH
DAYTIME HEATING AND THE UPPER TROUGH PROVIDING FORCING...SCT
SHRA/TSRA WILL DEVELOP WITH DAYTIME HEATING.

TEMPS WILL BE A LITTLE COOLER TODAY BUT DEWPOINT WILL STILL BE IN
THE UPPER 60S MAKING CONDITIONS FEEL MUGGY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/...
THE UPPER TROUGH WILL DIG INTO THE LOWER LAKES THRU FRI THEN CUTOFF
OVER THE LERI AREA INTO EARLY NEXT WEEK. THIS WILL KEEP THE AIRMASS
UNSETTLED THRU THE WHOLE PERIOD. NUMEROUS SHRA/TSRA WILL LIKELY
OCCUR EACH DAY. DOES NOT LOOK LIKE WIDESPREAD FLOODING WILL BE A
PROBLEM BUT LOCAL AREAS COULD SEE MINOR PROBLEMS IF REPEATED OR
PERSISTENT CONVECTIVE ACTIVITY OCCURS.

850 MB TEMPS DON'T COOL AS MUCH AS ONE WOULD THINK WITH THE UPPER
TROUGH. WIDESPREAD CLOUD COVER WILL BE PRESENT TO BUFFER THE DIURNAL
TEMP RANGE. DAYTIME TEMPS SHOULD STILL BE IN THE 70S WITH THE
COOLEST DAY GENERALLY EXPECTED TO BE SAT. LOWS WILL ONLY FALL INTO
THE LOW TO MID 60S.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
UPPER LEVEL TROUGH WILL PERSIST THROUGH THE EXTENDED FORECAST.
EXPECT TO SEE VARIABLE AMOUNTS OF CLOUD COVER BUT IN GENERAL IT
APPEARS WE WILL SEE MOSTLY CLOUDY CONDITIONS. THERE WILL LIKELY BE A
DIURNAL FLUCTUATION IN THE RAIN CHANCES WITH THE BEST CHANCES FROM
THE AFTERNOON UNTIL LATE EVENING THEN A LULL OVERNIGHT. HOWEVER
TIMING ANY PIECES OF ENERGY INTO THE UPPER LEVEL TROUGH WILL BE
DIFFICULT.

THE CLOUD COVER AND SCATTERED TO NUMEROUS SHOWERS/THUNDERSTORMS WILL
KEEP HIGHS NEAR TO SLIGHTLY BELOW SEASONAL AVERAGES.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
SHOWERS AND A FEW THUNDERSTORMS CONTINUE TO MOVE ACROSS NORTHERN
OHIO AND NW PA THIS MORNING. THE HEAVIEST THUNDERSTORMS WERE
MOVING ACROSS NW PA AND WILL OVER KERI SHORTLY. THERE SHOULD BE A
PERIOD OF LOCALLY HEAVY RAINFALL AND IFR CONDITIONS IN THE
THUNDERSTORMS. IFR CLOUD COVER ALSO COVERED A DECENT AMOUNT OF
NORTHERN OHIO FROM KCAK WESTWARD TO NW OHIO.

THERE SHOULD BE A BACK EDGE TO THE RAINFALL BY LATE MORNING INTO
THE AFTERNOON. CEILINGS SHOULD SLOWLY LIFT BACK TO LOW END VFR
LEVELS BY AFTERNOON ACROSS THE WEST AND NOT UNTIL MID AFTERNOON
ACROSS THE FAR EAST INTO NW PA. WE WILL THEN SEE IF ANY CONVECTION
CAN GET STARTED ACROSS THE WEST LATE IN THE AFTERNOON INTO THE
EVENING AS ANOTHER PIECE OF JET ENERGY DIVES INTO THE UPPER LEVEL
TROUGH.

.OUTLOOK...NON-VFR IN SCATTERED SHOWERS/THUNDERSTORMS AS WELL AS
EARLY MORNING FOG THROUGH MONDAY.

&&

.MARINE...
SEVERAL WAVES OF LOW PRESSURE WILL MOVE ACROSS THE CENTRAL GREAT
LAKES INTO THE WEEKEND. THE PRESSURE GRADIENT IS NEVER ALL THAT
STRONG AS AN UPPER LEVEL TROUGH PERSISTS ACROSS THE REGION. WE WILL
NEED TO MONITOR SUNDAY INTO MONDAY CLOSELY FOR THE WESTERN BASIN.
MODELS ARE INDICATING THAT A NORTHEAST FLOW WILL DEVELOP AND COULD
END UP PROVIDING A GOOD CHOP AROUND THE ISLANDS INTO WESTERN LAKE
ERIE. STILL SOME UNCERTAINTY IN THE MODELS SO NOT A LOT OF
CONFIDENCE IN THE FORECAST. ALL BOATERS WILL NEED TO KEEP AN EYE ON
THE FORECAST FOR SUNDAY INTO MONDAY.
