AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
745 AM EDT WED JUN 2 2010

.SYNOPSIS...
LOW PRESSURE WILL MOVE ACROSS THE SOUTHERN GREAT LAKES TODAY
WITH A FRONTAL BOUNDARY LINGERING OVER OHIO INTO NORTHWEST PA INTO
THURSDAY. ADDITIONAL RIPPLES OF LOW PRESSURE WILL MOVE ALONG THIS
FRONT ON THURSDAY. HIGH PRESSURE WILL BRIEFLY SLIDE INTO THE
REGION ON FRIDAY NUDGING THE FRONT INTO THE SOUTHERN PORTION OF THE
STATE. THIS BOUNDARY WILL WOBBLE BACK TO THE NORTH FOR THE WEEKEND
AS THE NEXT WAVE OF LOW PRESSURE BRINGS UNSETTLED WEATHER FOR THE
WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A MESOSCALE CONVECTIVE COMPLEX (MCC) WILL MOVE ACROSS INDIANA INTO
NORTHWEST OHIO THIS MORNING. A FEW THUNDERSTORMS COULD APPROACH
SEVERE LEVELS DURING THE MORNING AS AN OUTFLOW BOUNDARY FROM THIS
CONVECTION MOVES INTO THE REGION. THIS BOUNDARY WILL LIKELY BE A
FOCUS FOR ADDITIONAL THUNDERSTORMS THIS AFTERNOON INTO THE EVENING
AS STRONG MIDDLE LEVEL WINDS MOVE ACROSS THE SOUTHERN GREAT LAKES.
WILL ALSO HAVE TO MONITOR ANY MESOSCALE VORTEX THAT EMERGES FROM
THIS COMPLEX. THIS COULD ALSO BE A TRIGGER FOR CONVECTIVE INITIATION.
TRIED TO TIME THE CONVECTION INTO THE AREA THIS MORNING THEN EXPANDED
ACROSS THE REGION THROUGH THE AFTERNOON.

TEMPERATURES FOR TODAY ARE A DIFFICULT TASK WITH THE UNCERTAINTY
OF WHERE ANY OF THE MESOSCALE BOUNDARIES WILL BE BY AFTERNOON.
THIS COMBINED WITH ALL OF THE CONVECTIVE CLOUD DEBRIS THAT WILL
EXIST THROUGH THE DAY. AM COUNTING ON AT LEAST A SOME BREAKS FOR
THE AFTERNOON ACROSS MUCH OF THE AREA WHICH WILL ALLOW THE REGION
TO WARM INTO THE 80S. WARMEST TEMPERATURES WILL BE EAST OF A LINE
FROM ERIE TO MOUNT VERNON.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
THUNDERSTORMS SHOULD BE ONGOING THIS EVENING AS LOW PRESSURE MOVES
FROM LAKE ERIE INTO NY STATE. THIS WILL DRAPE A FRONT ACROSS THE
AREA AT SOME POINT DURING THE EVENING. THIS BOUNDARY WILL BECOME
THE FOCUS FOR CONVECTION. WILL HAVE TO MONITOR THE POTENTIAL FOR
FLOODING THIS EVENING INTO THE OVERNIGHT AS THUNDERSTORMS ATTEMPT
TO TRAIN ALONG THIS BOUNDARY. THERE IS ENOUGH UNCERTAINTY AS TO
WHERE THIS BOUNDARY WILL STALL TO KEEP US FROM ISSUING A FLOOD
WATCH AT THIS TIME. LATER SHIFTS WILL HAVE TO MONITOR THIS POTENTIAL
CLOSELY.

THE NEXT AREA OF LOW PRESSURE WILL MOVE ALONG THIS BOUNDARY ON
THURSDAY KEEPING SHOWERS AND THUNDERSTORMS IN THE FORECAST UNTIL
OVERNIGHT THURSDAY. AT THIS POINT THERE IS ENOUGH UNCERTAINTY ON
WHERE THIS BOUNDARY WILL RESIDE TO ONLY GO WITH LIKELY POPS. IF
THE BOUNDARY STALLS OVER THE CENTRAL PORTION OF THE COUNTY WARNING
AREA (CWA) THEN POPS WILL NEED TO BE RAISED. THE POSSIBILITY
EXISTS THAT THE REGION WILL SEE THE MAIN ENERGY SLIDE BY TO THE
NORTH AND SOUTH WITH ONLY SCATTERED THUNDERSTORMS MATERIALIZING.

OTHERWISE EXPECT TO SEE HIGH PRESSURE BUILD IN AT LEAST BRIEFLY ON
FRIDAY WITH THE FRONT HANGING UP ACROSS SOUTHERN OHIO. THIS FRONT
WILL MOVE BACK NORTHWARD FOR THE WEEKEND AS THE NEXT WAVE OF LOW
PRESSURE BRINGS UNSETTLED WEATHER TO THE REGION.

TEMPERATURES THROUGH THE PERIOD WILL VARY BY THE THICKNESS OF THE
CLOUD COVER ACROSS THE REGION. HOWEVER THEY SHOULD RANGE FROM THE
MIDDLE 70S TO THE LOWER 80S FOR THURSDAY THROUGH SATURDAY.

&&

.LONG TERM /SUNDAY THROUGH TUESDAY/...
MODELS IN AGREEMENT ENOUGH BEGINNING SUNDAY WITH KEEPING AT LEAST A
CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS THE AREA.
HOWEVER...OVERALL TREND WILL BE LOW PRESSURE AND UPPER TROUGH
GRADUALLY DEPARTING THE AREA THROUGH SUNDAY NIGHT AND SURFACE HIGH
PRESSURE BUILDING IN FOR MONDAY. FASTER AND MORE ZONAL FLOW DURING
EARLY NEXT WEEK LEADS TO QUESTION THE MODEL/S HANDLING OF SPEED OF
SYSTEMS OVERALL. WHILE LATEST ECMWF CONTINUES TO KEEP HIGH PRESSURE
DOMINATING ACROSS THE AREA GFS SPREADING MOISTURE BACK INTO THE AREA
AHEAD OF NEXT LOW PRESSURE PULLING OUT OF THE SOUTHERN PLAINS IN
COMBINATION OF NORTHERN STREAM LOW PRESSURE APPROACHING FROM THE
UPPER MIDWEST. TO ACCOUNT FOR THIS FASTER FLOW INTRODUCED LOW POPS
AT THE END OF THE PERIOD.

TEMPERATURES GOING INTO EARLY NEXT WEEK WILL BE NEAR NORMAL. STAYED
CLOSE TO GUIDANCE TEMPS FOR THE MONDAY AND TUESDAY PERIOD.

&&

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
THUNDERSTORM COMPLEX MOVING EAST THROUGH INDIANA THIS MORNING.
MENTION SOME TEMPO TSRA AT TOL AND FDY WITH GREATEST CONFIDENCE OF
THUNDER FROM THIS. AS THIS LINE OF THUNDERSTORMS PROGRESSES
EASTWARD VARIOUS MODEL GUIDANCE ALONG WITH CURRENT ANALYSIS
SUPPORT THIS FEATURE DIMINISHING QUICKLY AS IT PUSHES INTO
NORTHERN OHIO THROUGH THIS MORNING. MENTIONED ONLY SOME TEMPO
SHOWERS AT CLE AND MFD LATER THIS MORNING.

GOING INTO THE AFTERNOON...LINGERING OUTFLOW BOUNDARIES FROM THIS
MORNING/S THUNDERSTORMS WILL BE FOCUS FOR ANOTHER ROUND OF THUNDER
THIS AFTERNOON AND EVENING. MENTIONED THUNDER AT MOST LOCATIONS
WHILE TRYING TO LIMIT TIMING WITH REFERENCE TO LOCAL MODEL
GUIDANCE. FRONTAL BOUNDARY IS EXPECTED TO LINGER ACROSS NORTHERN
OHIO THIS EVENING AND INTO TONIGHT...SO WIND SHIFTS ARE TRICKY.
MOST GUIDANCE SUGGESTING AT LEAST MVFR CONDITIONS DEVELOPING AT
MOST SITES BETWEEN 06Z AND 12Z THURSDAY. FOR NOW FEEL SOMEWHAT
CONFIDENT IN SOME MVFR BUT HELD OFF ON AN IFR FORECAST AT THIS
TIME.

.OUTLOOK...NON VFR CONDITIONS THURSDAY. ANOTHER CHANCE OF NON VFR
FRIDAY NIGHT AND EARLY SATURDAY.

&&

.MARINE...
SOUTH TO SOUTHWEST WINDS TODAY OVER THE LAKE AHEAD OF COLD FRONT
EXPECTED TO PUSH THROUGH THE AREA TONIGHT. DEPENDING ON EVOLUTION OF
THUNDERSTORM COMPLEX TO THE WEST THIS MORNING...IT MAY HAVE AN
INFLUENCE ON WINDS LATER THIS MORNING OR EARLY AFTERNOON. OVERALL
WINDS WILL SHIFT TO THE WEST AND THEN BECOME NORTHERLY ON THURSDAY
WITH FRONT PUSHING SOUTH OF THE LAKE. HIGH PRESSURE BUILDING OVER
THE LAKE FRIDAY WILL ALLOW FOR MAINLY LIGHT AND VARIABLE WINDS.
ANOTHER APPROACHING LOW PRESSURE AND COLD FRONT WILL CAUSE WINDS TO
SHIFT BACK SOUTHERLY FRIDAY NIGHT AND SATURDAY MORNING. CONFIDENCE
LOWERS THROUGH THE WEEKEND AS POSITION OF FRONTAL BOUNDARY A BIT
UNCERTAIN. FOR NOW KEPT WINDS MORE SOUTHERLY WITH THE FRONT REMAIN
NEAR OR JUST NORTH OF THE LAKE.
