AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
746 AM EDT FRI JUN 13 2008

.SYNOPSIS...
A LARGE AREA OF HIGH PRESSURE ALONG THE EAST COAST FROM MAINE TO
FLORIDA WILL CONTINUE TO MOVE EAST OVER THE NEXT 48 HOURS. A COLD
FRONT FROM WESTERN LAKE SUPERIOR THROUGH IOWA TO KANSAS WILL MOVE
EAST ACROSS THE AREA EARLY SATURDAY MORNING. A RIDGE WILL BUILD
NORTHEAST INTO THE REGION SUNDAY. LOW PRESSURE WILL MOVE SOUTHEAST
INTO CENTRAL ONTARIO CANADA AND FORCE A COLD FRONT TO MOVE EAST
ACROSS THE REGION SUNDAY NIGHT INTO MONDAY MORNING. HIGH PRESSURE
WILL BUILD EAST MONDAY NIGHT AND TUESDAY INTO THE REGION. THE HIGH
PRESSURE WILL DISSIPATE OVER THE AREA AS YET ANOTHER HIGH PRESSURE
BUILDS SOUTHEAST TOWARD THE AREA ON THURSDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
SOUTH TO SOUTHWEST FLOW WILL CONTINUE TODAY AHEAD OF THE COLD
FRONT PRIMING THE ATMOSPHERE FOR THE POTENTIAL FOR SEVERE WEATHER
ACROSS THE AREA. THETA E AXIS GRADUALLY SLIDES EAST ACROSS THE
REGION LATER THIS AFTERNOON INTO TONIGHT. THE THETA E RIDGE
SIGNIFIES FAIRLY STRONG AXIS OF ABUNDANT MOISTURE. THIS APPEARS TO
BE THE CASE AS GULF MOISTURE WILL BE WIDE OPEN PUMPING COPIOUS
AMOUNTS OF MOISTURE INTO THE FORECAST AREA.

THE COMBINATION OF THE WARM UNSTABLE ATMOSPHERE AND LIKELY
OUTFLOWS FROM EARLIER CONVECTION EXPECTED ACROSS THE AREA WILL
LIKELY CREATE A POTENTIAL FOR SOME STRONG TO SEVERE THUNDERSTORMS
THIS AFTERNOON.

PRECIPITABLE WATER VALUES EXCEED TWO INCHES AT TIMES THIS
AFTERNOON ACROSS THE AREA. AREA OF STORMS WILL LIKELY HAVE A SLOW
EASTWARD PROGRESSION BUT THE INDIVIDUAL CELLS WILL LIKELY TRAIN
OVER AREAS WHERE RAIN WILL HAVE ALREADY FALLEN. THIS COULD CAUSE
SOME PROBLEMS WITH STREAMS AND CREEKS. THREAT FOR SEVERE WEATHER
AND FLOODING WILL HAVE TO BE MONITORED CLOSELY ONCE CONVECTION
DEVELOPS.

STRONG WARM AIR ADVECTION INTO THE AREA WILL CONTINUE TO PUMP
QUITE WARM AIR INTO THE REGION TODAY. DEW POINTS ALREADY IN THE
UPPER 60S AND MAY TOUCH THE 70 DEGREE MARK TODAY. I AM LEANING ON
GOING WITH HIGHS IN THE UPPER 80S TO LOWER 90S ACROSS THE FORECAST
AREA FOR TODAY.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/...
CONVECTION IS EXPECTED TO BE ONGOING AND WILL CONTINUE TO BE
DRIVEN BY LINGERING INSTABILITY AHEAD OF THE COLD FRONT ALONG WITH
FURTHER OUTFLOW BOUNDARIES TONIGHT. SHOWERS AND THUNDERSTORMS WILL
LIKELY KEEP THEIR SEVERE THRESHOLDS GOING INTO THE NIGHT UNTIL THE
COLD FRONT MOVES EAST OF THE AREA AROUND 12Z TO 15Z. FORECAST AREA
SHOULD SEE GRADUAL IMPROVEMENT THROUGH THE DAY SATURDAY AS
ACTIVITY MOVES TO THE EAST.

TEMPERATURES WILL REMAIN WELL INTO THE 60S DURING THE NIGHT
TONIGHT IN THE WARM AIR MASS AHEAD OF THE COLD FRONT.

SATURDAY WILL SEE A RETURN BACK TO COOLER TEMPERATURES AS COLD AIR
ADVECTION TAKES PLACE IN THE WAKE OF THE FRONT.

I DONT ANTICIPATE PERFECTLY CLEAR SKIES SATURDAY NIGHT AS MOISTURE
RACES SOUTHEAST TOWARD THE AREA AHEAD OF THE NEXT FRONTAL
BOUNDARY AND ANY THUNDERSTORMS ASSOCIATED WITH THE FRONT WILL
LIKELY PRODUCE A HIGH CIRRUS CLOUD DECK OVER THE REGION. COLD
FRONT SLIDES EAST INTO THE AREA SUNDAY EVENING. WILL THEREFORE
KEEP MENTION OF SHOWERS AND THUNDERSTORMS SUNDAY AFTERNOON INTO
SUNDAY NIGHT. TEMPERATURES WILL REBOUND SLIGHTLY ON SUNDAY INTO
THE LOWER 80S BUT THEN DROP BACK OFF INTO THE 70S AGAIN BY MONDAY
IN THE WEAK COLD AIR ADVECTION PATTERN.

LINGERING SCATTERED SHOWER ACTIVITY WILL THEN PUSH OFF TO THE
SOUTHEAST MONDAY NIGHT. COOLER TEMPERATURES IN THE 50S EXPECTED
MONDAY NIGHT.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
COLD FRONT SHOULD BE WELL EAST OF THE AREA ON TUESDAY WITH HIGH
PRESSURE STARTING TO BUILD IN FROM THE NORTHERN AND CENTRAL PLAINS.
HOWEVER APPEARS THAT A SURFACE LOW WILL BE LINGERING IN THE SOUTHERN
QUEBEC OR NEW ENGLAND AREA ON TUESDAY WHILE A DEEP UPPER LOW IS
SLOWLY ROTATING SOUTHEAST INTO EASTERN ONTARIO.  THESE SYSTEMS MAY
PROVIDE ENOUGH INSTABILITY AND FORCING FOR SOME SHOWERS MAINLY IN
EASTERN AREAS FOR BOTH TUESDAY AND WEDNESDAY. FOR NOW WILL CONTINUE
WITH CHANCE POPS OVER THE EAST THIRD TUESDAY AND SLIGHT CHANCE OVER
THE SAME AREA ON WEDNESDAY. GFS AND ECMWF ARE BOTH SHOWING THE
DEVELOPMENT OF THIS UPPER LEVEL LOW THOUGH DIFFER ON HOW QUICKLY TO
MOVE IT OUT. THE GFS HOLDS THE UPPER LEVEL LOW BACK OVER THE
EASTERN AND CENTRAL GREAT LAKES AREA LONGER. PREFER ECMWF BEING
SOMEWHAT FASTER PULLING THE LOW AWAY WHICH ALSO AGREES WITH GFS
ENSEMBLES. WITH THIS UPPER LEVELS LOW OVER THE GREAT LAKES REGION
EXPECTING BELOW NORMAL TEMPERATURES DURING THIS PERIOD.

&&

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
THERE WERE FEW SHOWERS OVER EXTREME NE OH AND NW PA THIS MORNING
ASSOCIATED WITH WARM FRONT AND HAVE LIFTED NE OF THE AREA. ANOTHER
BAND OF HEAVIER SHOWERS AND THUNDERSTORMS OVER INDIANA AND INTO SE
LOWER MI DEVELOPED IN ACCESS OF DEEPER MOISTURE AND INSTABILITY
THIS MORNING. EXPECT SOME OF THESE THUNDERSTORMS TO MOVE INTO THE
TOL AND FDY AREA THIS MORNING BUT THEN LIKELY DIMINISH AS THEY
MOVE OUT AHEAD OF THE UPPER LEVEL JET AND STRONGER INSTABILITY THAT
WILL DEVELOP NEAR THE COLD FRONT THIS AFTERNOON. SCATTERED
THUNDERSTORMS MAINLY WEST AND CENTRAL THIS AFTERNOON THEN THEY
BECOME NUMEROUS THIS EVENING AND TONIGHT AS THE MOISTURE
INCREASES AND THE FRONT GETS CLOSER. VFR CONDITIONS EXCEPT IN
THUNDERSTORMS.

OUTLOOK...SHOWERS/STORMS WILL CONTINUE TO PUSH EAST AND EXIT THE
AREA SATURDAY MORNING. CUMULUS/STRATOCUMULUS MAY LINGER ON
SATURDAY BUT CEILINGS SHOULD GRADUALLY IMPROVE TO VFR. VFR WEATHER
EXPECTED SUNDAY WITH WEAK HIGH PRESSURE OVER THE AREA. SECONDARY
COLD FRONT EXPECTED TO MOVE THROUGH SUNDAY NIGHT/EARLY MONDAY WITH
MVFR CONDITIONS LIKELY TO DEVELOP IN A FEW SHOWERS AND
THUNDERSTORMS. WEAK HIGH PRESSURE TO BUILD IO ON MONDAY WITH VFR
CONDITIONS EARLY IN THE WEEK.

&&

.MARINE...
HIGH PRESSURE MOVING OFF TO THE EAST TODAY WHILE A COLD FRONT
APPROACHES FROM THE WEST. IT WILL MOVE ACROSS THE LAKE TONIGHT. SW
FLOW WILL BE ON THE INCREASE TODAY BUT WINDS AND WAVES SHOULD STAY
BELOW SMALL CRAFT ADVISORY CRITERIA. WINDS WILL SHIFT TO THE WEST AS
THE COLD FRONT MOVES THROUGH OVERNIGHT. HIGH PRESSURE BUILDS IN
QUICKLY FROM THE SW ON SATURDAY. WITH THE WEAK HIGH BUILDING IN
QUICKLY ON SATURDAY WINDS WILL LIKELY BE WESTERLY EARLY THEN BACK TO
THE SW LATER IN THE DAY. THUNDERSTORMS WILL WILL BECOME WIDESPREAD
ON THE WEST END OF THE LAKE BY LATE AFTERNOON OR EVENING THEN SPREAD
ACROSS THE LAKE. STRONG GUSTY WINDS WITH THESE THUNDERSTORM ARE
POSSIBLE LATE TODAY...TONIGHT AND EARLY SATURDAY. ANOTHER WEAK COLD
FRONT WILL MOVE THROUGH SUNDAY NIGHT WITH ANOTHER ROUND OF SHOWERS
AND THUNDERSTORMS POSSIBLE. AT THIS TIME DOESNT APPEAR THAT WINDS
OR WAVES WILL REACH SMALL CRAFT CRITERIA THROUGH TUESDAY.
