SETTLE OVER THE GREAT LAKES AND OHIO VALLEY FOR THURSDAY AND
FRIDAY. THE NEXT WEATHER DISTURBANCE WILL AFFECT US OVER THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
COLD FRONT AS OF 4 AM WAS LOCATED FROM NEAR DETROIT MI TO
VALPARAISO IN. THIS FRONT CONTINUES TO MAKE PROGRESS SOUTHEAST AND
HAD INITIATED A LINE OF SHOWERS/THUNDERSTORMS TO DEVELOP ALONG THE
FRONT...JUST ENOUGH UPPER SUPPORT. FOLLOWING THE MORE RECENT HRRR
RUNS...HAVE TAKEN THIS LINE TO THE I-71 CORRIDOR WHILE ALLOWING IT
TO WEAKEN. MAY HAVE SOME NEW DEVELOPMENT TOWARD MIDDAY ACROSS THE
SOUTHEAST...BUT PRECIP SHOULD BE OUT OF HERE BY LATE
AFTERNOON/EARLY EVENING. TEMPERATURES COOLER TODAY...CLOUD
COVER...SHOWERS..AND THEN THE COLD AIR ADVECTION. WILL HAVE HIGHS
TODAY IN THE 70S. WILL KEEP MOSTLY CLOUDY SKIES THROUGH THE LATE
AFTERNOON. WINDS WILL SHIFT TO THE NORTH WITH THE FRONTAL PASSAGE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
MOST IF NOT ALL OF THE PRECIPITATION WILL HAVE EXITED THE AREA BY
6 PM TONIGHT. WILL GET GRADUAL CLEARING OVERNIGHT AND LOWS WILL
GET BACK INTO THE 50S.

CANADIAN HIGH PRESSURE SETTLES OVER THE REGION TO END THE WORK
WEEK. AS HAS BEEN FAIRLY TYPICAL THIS SUMMER...HIGHS WILL BE IN
THE 70S AND NIGHT LOWS IN THE 50S.

EITHER SIDE OF 80.

&&

.LONG TERM /SUNDAY THROUGH TUESDAY/...
SUNDAY IS A TRICKY FORECAST DAY. THE SHOWERS PROGGED TO PUSH ACROSS
THE FORECAST AREA ON SATURDAY/SATURDAY NIGHT SHOULD BE MOVING OFF TO
THE EAST. SOME OF THE GUIDANCE SHOWS A BUBBLE OF WARM AIR SLIDING
ACROSS THE MIDWEST AND OHIO VALLEY AND THIS WARMER AIR COULD BRUSH
THE AREA. MEANWHILE...COLD FRONTOGENESIS IS PROGGED TO DEVELOP OVER
THE CENTRAL GREAT LAKES SO THERE MAY BE A RETURN OF SHOWERS AND
STORMS AS THE FRONT BEGINS TO MOVE SOUTHEAST. WILL FORECAST HIGH
TEMPERATURES NEAR NORMAL BUT THE ACTUAL TEMPS COULD BE A FEW DEGREES
ABOVE OR BELOW THAT DEPENDING ON THE CLOUDS AND SHOWERS. BY MONDAY
THE COLD FRONT SHOULD BE SOUTH OF THE AREA AND THE NEXT COOL DOWN
SHOULD BE UNDERWAY. HIGHS MAY STRUGGLE TO GET MUCH ABOVE 70 IF IT IS
CLOUDY AND SHOWERY. THE MODELS ARE TRENDING COLDER BY TUESDAY WITH
850 MB TEMPERATURES ONLY AROUND 6C. WILL KEEP A CHANCE OF SHOWERS
ACROSS NE OH/NW PA. FORECAST TEMPS WILL BE SOME 10 DEGREES OR SO
BELOW NORMAL.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
SHOWERS AND THUNDERSTORMS EXPANDING ON THE OUT FLOW FROM THE
EARLIER STORMS IN LOWER MICHIGAN AND THESE SHOWERS AND STORMS WILL
CROSS THE FORECAST AREA EARLY THIS MORNING. THE ACTUAL FRONT
WILL BE SLOWER TO ADVANCE AND WILL TAKE UNTIL LATE MORNING AT
INLAND TAF SITES KMFD KCAK AND KYNG AND WILL ALLOW FOR ADDITIONAL

.MARINE...
THE COLD FRONT WILL DROP ACROSS LAKE ERIE EARLY THIS MORNING. THE
WINDS BEHIND THE FRONT INCREASE TO MODERATE LEVELS INITIALLY AND
THE LAKE WILL BE CHOPPY AT TIMES TODAY. THE BEST CHANCE FOR WINDS
AND WAVES TO EXCEED SMALL CRAFT ADVISORY CRITERIA WILL BE TONIGHT AS
THE PRESSURE RISES SHOULD BOOST THE NORTH WINDS TO ABOUT 20 KNOTS OR
SO. WINDS AND WAVES SHOULD BEGIN TO DIMINISH THURSDAY AS THE SURFACE
HIGH BUILDS EAST ACROSS THE LOWER GREAT LAKES. THE HIGH SHOULD MOVE
EAST OF THE AREA BY FRIDAY NIGHT AND WINDS SHOULD COME AROUND FROM
