.LONG TERM /SATURDAY THROUGH TUESDAY/...
-- Changed Discussion --
THE RIDGE IS PROGGED TO BUILD OVER THE MIDDLE OF THE COUNTRY THIS
WEEKEND AND THEN SHIFT EAST. THE SURFACE HIGH OVER THE NORTHEAST
WILL BEGIN TO RETREAT...AND TAKE THE DRY AND MORE STABLE AIR WITH
IT. SHOWERS AND THUNDERSTORMS WILL LIKELY BEGIN TO TOP THE RIDGE AS
EARLY AS SATURDAY. WE MIGHT HANG ON TO A DRY DAY ON SATURDAY...AT
LEAST ACROSS NE OH/NW PA. THE GFS IS OFTEN OVER DONE WITH CONVECTIVE
FEEDBACK AND THIS LOOKS TO BE THE CASE MUCH OF THE WEEKEND. WILL
BEGIN WITH A 30 PERCENT CHANCE OF SHOWERS/STORMS ACROSS NW OHIO ON
SATURDAY. WILL FORECAST A SMALL CHANCE OF SHOWERS AND STORMS OVER
THE ENTIRE FORECAST AREA SUNDAY AND MONDAY. IT WILL PROBABLY NOT BE
RAINY ON SUNDAY OR MONDAY. IN FACT WE COULD GET BY WITH VERY LITTLE
IN THE WAY OF SHOWERS/STORMS UNLESS WE GET HUNG UP WITH A
OUTFLOW/MESO BOUNDARY IN THE AREA. WILL INCREASE THE CHANCE OF
SHOWERS/STORMS BY TUESDAY AS THE NEXT FRONT REACHES THE AREA. SUMMER
TEMPERATURES WILL ARRIVE AS THE RIDGE BUILDS IN. WE SHOULD SEE HIGHS
THIS WEEKEND GET BACK TO 80 OR BETTER.

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
VFR CONDITIONS WILL CONTINUE. THE WARM FRONT WILL WORK ITS WAY
NORTH OF THE AREA. THE FRONT IS ALREADY SHIFTING NORTH OF KFDY AND
KTOL WITH GUSTY SOUTH WINDS THIS AFTERNOON. A SERIES OF WEAK WAVES
WILL SLIDE ALONG THE WARM FRONT...CAUSING LITTLE MORE THAN A FEW
SPRINKLES OR A LIGHT SHOWER...MAINLY AT KERI. WINDS WILL DIMINISH
A BIT TONIGHT...THEN PICK BACK UP AGAIN WED MORNING AHEAD OF A
COLD FRONT DROPPING SOUTHEAST ACROSS THE GREAT LAKES ON
WEDNESDAY.

.OUTLOOK...SHORT LIVED NON-VFR POSSIBLE IN SHOWERS OR
THUNDERSTORMS WEDNESDAY AFTERNOON/EVENING... AND AGAIN SATURDAY
AND SUNDAY.

.MARINE...
-- Changed Discussion --
SOUTHERLY WINDS ON LAKE ERIE TONIGHT WILL SHIFT TO SOUTHWESTERLY ON
WEDNESDAY MORNING AS A WARM FRONT LIFTS NORTH ACROSS THE LAKE.
FORTUNATELY THE WARMER AIR WILL CREATE STABLE CONDITIONS AND LIMIT
THE 30-40 KNOTS AT 925MB FROM MIXING DOWN TO THE SURFACE. WITH THAT
SAID...THERE WILL BE ABOUT A SIX HOUR WINDOW WHERE WINDS WILL
APPROACH SMALL CRAFT ADVISORY CONDITIONS. WILL ALLOW THE NEXT SHIFT
TO MONITOR THE STRENGTH OF THE GRADIENT AND UPSTREAM WINDS TO
DETERMINE IF A BRIEF SMALL CRAFT ADVISORY WILL BE NEEDED.

THIS SYSTEM WILL PULL A COLD FRONT BACK SOUTH ACROSS LAKE ERIE LATER
IN THE DAY WEDNESDAY. HIGH PRESSURE WILL THEN SLOWLY BUILD EAST
ACROSS THE GREAT LAKES THROUGH THE REGION. ABOVE NORMAL TEMPERATURES
AND WINDS GENERALLY 10 KNOTS OR LESS WILL COMBINE FOR A PROLONGED
STRETCH OF WAVES LESS THAN 2 FEET.
