AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CLEVELAND OH
628 PM EDT SAT JUN 1 2013
.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA SUNDAY. IN ITS WAKE HIGH
PRESSURE WILL BRING COOLER AND LESS HUMID AIR TO THE REGION. THE
HIGH WILL BEGIN TO SHIFT EAST WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
NO CHANGES TO ORIGINAL FORECAST FOR 630 UPDATE.
ORIGINAL DISCUSSION...
RADAR STARTING TO SHOW ECHOES DEVELOPING...FINALLY BEING ABLE TO
SEE THE BOUNDARIES THAT ARE OUT THERE. WE HAVE DESTABILIZED
ENOUGH. SO EXPECT SCATTERED THUNDERSTORMS DEVELOPMENT GOING INTO
THE LATE AFTERNOON HOURS...WITH THE SEVERE POTENTIAL REMAINING.
WITH A DECENT SHORTWAVE ADVERTISED TONIGHT EXPECT SHOWERS TO FILL
IN WITH EMBEDED THUNDER CONTINUING OVERNIGHT. GUIDANCE IS HIGH
TONIGHT FOR POPS TOO. KEPT THE HEAVY RAIN MENTION. ANY OF THE TS
THIS EVENING HAVE THE POTENTIAL TO RELEASE A LOT OF RAIN IN A
SHORT AMOUNT OF TIME. LATER TONIGHT...SHOWERS WOULD BE MORE
MODERATE IN NATURE. COLD FRONT IS STILL WELL TO THE WEST. LOWS
TONIGHT IN THE 60S.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY NIGHT/...
QUESTION IS HOW LONG TO LINGER ANY SHOWERS AND TS INTO SUNDAY.
TRUE COLD FRONT WILL WAIT TO CROSS UNTIL THE AFTERNOON HOURS. SO
MAY HAVE A FEW ISOLATED SHOWERS WITH THAT FEATURE...BUT REDUCED
POPS AS WE ARE DRIER BEHIND THE EARLY MORNING PREFRONTAL TROUGH.
MORE SEASONABLE HIGH TEMPS FOR THE DAY.
HIGH PRESSURE WILL BRING A PERIOD OF COOLER TEMPERATURES TO THE
REGION GOING INTO MID WEEK. MONDAY WILL BE THE COOLEST DAY WITH
TEMPS RANGING FROM THE LOWER TO MID 60S. NIGHT LOWS WILL GET INTO
THE 40S. INLAND NW PA COULD FLIRT WITH THE UPPER 30S IF WINDS
LIGHTEN UP ENOUGH BY TUESDAY MORNING. MAY SEE SOME LAKE CLOUDS
LINGERING SUNDAY NIGHT AND INTO MONDAY...BUT EVENTUALLY WILL SEE
MOSTLY SUNNY SKIES.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
THE LONG TERM BEGINS ON WEDNESDAY WITH THE GFS AND ECMWF IN DECENT
GENERAL AGREEMENT SHOWING UPPER LEVEL LOW PRESSURE OVER THE
DAKOTAS. AT THE SURFACE HIGH PRESSURE WILL BE CENTERED OVER WESTERN
QUEBEC AND ONTARIO WHILE LOW PRESSURE WILL BE IN MINNESOTA WITH A
WARM FRONT AND DEEP MOISTURE FROM THERE INTO THE MID MISSISSIPPI
VALLEY. AS THE REGION WILL BE UNDER THE INFLUENCE OF THE SURFACE
HIGH TO OUR NORTH WILL KEEP WEDNESDAY DRY. 850MB TEMPS 8-10C WILL
RESULT IN HIGHS IN THE 70S. THURSDAY AND FRIDAY ALL SYSTEMS SHIFT
EAST WITH THE SURFACE HIGH MOVING OUT TO SEA THE UPPER LOW MOVING
ACROSS THE GREAT LAKES REGION AS DOES ITS SURFACE REFLECTION. THUS
WHILE TEMPS INCREASE A FEW DEGREES EACH DAY SO WILL THE CHANCE FOR
SHOWERS AND THUNDERSTORMS. WITH THE INCREASING MOISTURE...BROUGHT
CHANCE POPS /40-50%/ INTO THE AREA THURSDAY THROUGH FRIDAY. TRIMMED
POPS BACK TO 20-30% FRIDAY NIGHT AND MAINLY DRY SATURDAY AS ANOTHER
SURFACE HIGH BUILDS IN BEHIND THE SYSTEM. TEMPS GENERALLY NEAR
NORMAL.
&&
.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
VFR AT 17Z ACROSS NRN OHIO AND NWRN PA. RADAR SHOWS LIGHT RAIN
SHOWERS FROM JUST WEST OF KCLE SSW THROUGH THE MNN AREA. SURFACE
PLOT SHOWING WINDS ARE CONVERGENT IN THAT AREA. MEANWHILE THE
AIRMASS CONTINUES TO WARM AND BECOME LESS STABLE ESPECIALLY ACROSS
THE EAST HALF OF THE AREA WHERE TEMPS HAVE REACHED 80 OR A COUPLE
DEGREES ABOVE AND LI'S ARE NOW -3 TO -5C. EXPECT CONVECTION TO
DEVELOP THIS AFTERNOON EITHER ALONG THE CONVERGENCE IN NORTH
CENTRAL OHIO OR POINTS WEST ALONG ANOTHER AXIS OF MOISTURE MOVING
INTO THE AREA. MOST ENERGY EAST HALF SO EXPECT STRONGEST
CONVECTION THERE. LOOKING FOR VFR TO CONTINUE INTO THE AFTERNOON
DROPPING TO MVFR OR IFR BRIEFLY IN CONVECTION. OVERNIGHT CIGS WILL

BASED ON WINDS AROUND 20 KNOTS GUSTING TO AROUND 30 KNOTS. RIGHT
ALONG THE SHORE WAVES MAY NOT QUITE BE 4 FEET GIVEN FLOW FROM THE
SOUTH BUT JUST A BIT OFFSHORE WOULD EXPECT 4 FOOT WAVES. THROUGH

SMALL CRAFT CRITERIA BUT STILL SHOULD BE A GOOD CHOP THROUGH THE
