AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
133 PM EDT FRI MAY 2 2008

.SYNOPSIS...
A WARM FRONT ACROSS LAKE ERIE WILL MOVE NORTH TODAY. LOW PRESSURE
OVER MISSOURI WILL MOVE NORTHEAST TO UPPER MICHIGAN TONIGHT AND
THEN INTO ONTARIO SATURDAY. THE ASSOCIATED COLD FRONT WILL MOVE
ACROSS THE REGION SATURDAY AFTERNOON AND EVENING. HIGH PRESSURE
WILL BUILD IN FOR SUNDAY AND MONDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
BASED ON CURRENT RADAR UPDATED FORECAST TO TAKE OUT THE TIMING ON
THE CHANCE OF THUNDERSTORMS. LIGHTNING DETECTION...OBS AND RADARS
SHOWING SOME THUNDERSTORMS IN THE SHOWERS ACROSS MUCH OF THE AREA.
PRECIP ALSO RATHER WIDESPREAD ACROSS THE NORTH SO UP POPS NORTH
CENTRAL AND NE OHIO TO LIKELY THIS MORNING THEN BACK TO CHANCE
DURING THE AFTERNOON. WARM FRONT ACROSS LAKE ERIE SHOULD MOVE
NORTH OF THE LAKE TODAY. THE GFS KEEPS THE WARM FRONT HANGING
AROUND NW PA WHILE THE NAM MOVES IT WELL NORTH. WITH THE TRACK OF
THE SURFACE LOW THE WARM FRONT SHOULD MOVE NORTH...SO MORE LEANING
TOWARD THE NAM. HIGH TEMPERATURES SHOULD REACH THE MID 70S OVER
MOST OF THE AREA.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
THE HIGHEST POPS SHOULD BE WEST AS THE COLD FRONT APPROACHES. THE
QUESTION IS...IS THERE A THREAT ALL NIGHT. THE GFS TRIES TO KEEP THE
EAST DRY THIS EVENING...ON THE EDGE ABOUT THIS. WILL FORECAST A
CHANCE WITH SOME MOISTURE AROUND.

AS THE COLD FRONT MOVES THROUGH SATURDAY LIKELY LOOKS GOOD AT THE
MOMENT. THE GFS IS QUICKER THAN THE NAM...NOT SURE WHICH WILL BE
RIGHT...SO KEPT A CHANCE OF SHOWERS AND THUNDERSTORMS IN THE EVENING
EVERYWHERE AND THEN A CHANCE OF SHOWERS AFTER THAT. WITH THE HIGH
STARTING TO BUILD IN SUNDAY JUST KEPT THE POPS 20 PERCENT...IT SEEMS
VERY DRY AND ANTI CYCLONIC AND NO REAL SHORT WAVE. ALL 3
MODELS...THE NAM...GFS AND ECMWF HAVE NO QPF SUNDAY.

HIGH PRESSURE WILL BE IN CONTROL SUNDAY NIGHT THROUGH MONDAY NIGHT
WITH DRY WEATHER.

LOWS TONIGHT SHOULD BE MILD IN THE SOUTHERLY FLOW. FORECAST HIGHS ON
SATURDAY A LITTLE TOUGH IF THERE ARE SOME BREAKS ESPECIALLY IN THE
EAST...WENT CLOSE TO GUIDANCE MOS MAV. FOR SUNDAY AFTER FROPA AND
WITH 850 MB TEMPERATURES NEAR 0C WENT COLDER THAN GUIDANCE. WITH
HIGH PRESSURE IN CONTROL SUNDAY NIGHT AND MONDAY NIGHT ALSO WENT
COLDER THAN GUIDANCE. THE 00Z MEX NUMBERS LOOK GOOD. ALSO USED LOCAL
SCHEMES TO COME UP WITH THE TEMPERATURES.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
MAJOR MODEL DIFFERENCES BETWEEN THE EUROPEAN AND GFS DURING THE LONG
TERM PERIODS. CONSENSUS APPEARS TO BE THE EUROPEAN AS THE MODEL OF
CHOICE.

FORECAST EXPECTED TO REMAIN DRY TUESDAY AND WEDNESDAY AS
RIDGING BUILDS EAST ACROSS THE REGION. TIMING OF LOW PRESSURE
PROGGED TO MOVE EAST ACROSS THE CENTRAL UNITED STATES WILL INFLUENCE
ONSET OF CHANCE OF SHOWERS AND THUNDERSTORMS. CURRENT FORECAST
LEANING TOWARD A SLIGHT CHANCE OF PRECIPITATION LATE WEDNESDAY NIGHT
AND A CHANCE OF THUNDERSTORMS THURSDAY AHEAD OF THE WARM FRONT.

UPPER LEVEL TROUGH DIGS SOUTHEAST INTO THE FORECAST AREA ON SATURDAY
AND MID TO UPPER LEVEL LOWS BECOME NEARLY STACKED OVER THE WESTERN
GREAT LAKES BY SATURDAY EVENING. THIS SHOULD KEEP FORECAST AREA IN A
PATTERN OF COOL AIR ALOFT AND WARM AIR ADVECTION AT THE SURFACE
THURSDAY THROUGH SATURDAY.  COMBINATION OF WARM SURFACE TEMPERATURES
AND COOL TEMPERATURES ALOFT COULD ENHANCE INSTABILITY AND
THUNDERSTORM THREAT.

MADE VERY LITTLE CHANGE TO THE LONG TERM FORECAST DUE TO LOW
CONFIDENCE IN MODEL SOLUTIONS AT THIS TIME.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
LINE OF CONVECTION EXTENDING FROM THE TOL AREA THROUGH MEDIAN
COUNTY TO NEAR KYNG. THIS LINE IS MOVING NORTHEAST ALTHOUGH
MOVEMENT ON THE EAST END OF THE LINE IS SLOWER THAN THE WEST END
DUE IN PART TO THE MORE STABLE AIRMASS ACROSS EXTREME NERN OHIO
AND NWRN PA. MOST AREAS WILL SEE A BREAK IN THE CONVECTION FOR A
COUPLE HOURS BEFORE THE LINE ACROSS INDIANA MOVES INTO THE AREA.
BROUGHT THE LINE INTO TOL AND FDY AREAS AFTER 20Z AND KMFD AFTER
22Z. WILL NOT BRING IT FURTHER EAST AT THIS POINT AS THIS COULD
WEAKEN IN FAVOR OF ANOTHER LINE DEVELOPING TO THE WEST AND TAKING
OVER. FOR THE LATE OVERNIGHT HOURS HAVE FOLLOWED THE NAM12 UVV
WHICH BRINGS A LINE THROUGH THE CLE AREA AROUND 09Z. WILL BRING IN
A TEMPO GROUP WITH TSRA FOR THAT PRIOD AND ATTEMPT TO TILE ITS
MOTION EAST.

OUTLOOK...COLD FRONT IS EXPECTED TO MOVE THROUGH THE AREA ON
SATURDAY ALLOWING FOR NEXT POSSIBLE CHANCE FOR MVFR CONDITIONS.
LINGERING UPPER LOW ACROSS THE AREA ON SUNDAY WILL ALLOW FOR
CONTINUED CLOUD COVER AND THE CHANCE FOR SHOWERS...THEN HIGH
PRESSURE BUILDS IN SUNDAY NIGHT ALLOWING FOR CLEARING SKIES BY
MONDAY MORNING FROM WEST TO EAST.

&&

.MARINE...
HAVE DIVIDED THE LAKE WITH THE FRONT THIS MORNING SPLITTING THE
WEST/EAST. WEST END SOUTH OF THE FRONT WITH SOUTHERLY WINDS...EAST
END MAINTAINING EAST WINDS. FRONT WILL LIFT NORTH LATER THIS
AFTERNOON/EVENING. GENERALLY WENT 1 TO 3 FEET ON THE LAKE WITH
VEERING WINDS EAST END...AND SOUTHERLY FLOW ELSEWHERE. SHOWERS AND
THUNDERSTORMS POSSIBLE ACROSS THE LAKE FROM TODAY THROUGH
SATURDAY.  WINDS DO INCREASE TONIGHT FROM WEST TO EAST ACROSS THE
LAKE AS THE COLD FRONT APPROACHES. COLD FRONT SWEEPS EAST ACROSS
THE LAKE SATURDAY NIGHT AND THEN WINDS GRADUALLY DIMINISH IN TIME
BY SUNDAY NIGHT TO LIGHT AND VARIABLE WHICH CONTINUES THROUGH
TUESDAY. WINDS AND WAVES SHOULD NOT EXCEED SMALL CRAFT ADVISORY
CRITERIA THROUGH THE NEXT 5 DAYS.
