.SYNOPSIS...
AN AREA OF HIGH PRESSURE CENTERED OVER SOUTHERN OHIO WILL BUILD
NORTH ACROSS THE AREA TODAY. THIS HIGH WILL SHIFT TO THE CAROLINAS
TONIGHT. LOW PRESSURE WILL PASS TO THE NORTH OF LAKE ERIE LATE SUNDAY
AND DRAG A COLD FRONT ACROSS THE REGION BY EARLY MONDAY. ANOTHER
AREA OF HIGH PRESSURE WILL BUILD OVER THE REGION FROM THE SOUTHWEST
MONDAY AND TUESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THINGS HAVE QUIETED DOWN AND PRECIP IS NOW OVER. AREA OF CLEARING
CONTINUES TO MAKE GOOD PROGRESS TO THE EAST. CLEARING SHOULD BE
THROUGH KMFD AND EAST OF KCLE AND KCAK BETWEEN 10 AND 11Z OR SO.
BY MIDDAY...EVEN NW PA SHOULD BE PARTLY CLOUDY. ABUNDANT SUNSHINE
THIS AFTERNOON COMBINED WITH DECENT WARM AIR ADVECTION SHOULD PUSH
TEMPS 5 TO 10 DEGREES WARMER THAN FRIDAY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/...
MODELS SHOWING SOME TIMING DIFFERENCES DURING THE PERIOD WITH THE
NAM NOTICEABLY FASTER THAN THE GFS. EXPECT HIGH CLOUDS TO INCREASE
OVERNIGHT AS THE SURFACE HIGH SHIFTS TO THE CAROLINAS. LOW
PRESSURE WILL PASS TO THE NORTH OF LAKE ERIE SOMETIME LATE SUNDAY.
NAM FASTER WITH THIS LOW AND ASSOCIATED COLD FRONT BUT WILL TREND
TOWARD THE SLOWER GFS WHICH HAS BEEN MORE CONSISTENT AS OF LATE.
THIS MEANS THAT MUCH IF NOT ALL OF SUNDAY SHOULD BE DRY. HAVE
BACKED OFF ON PRECIP MENTION DURING THE MORNING HOURS SUNDAY WITH
CHANCE POPS IN THE AFTERNOON. MOST OF THE AREA WILL SEE LIKELY
WORDING SUNDAY NIGHT BUT QPF AMOUNTS SHOULD BE NO MORE THAN A
TENTH OR TWO. THERE WILL BE SOME DECENT COLD AIR ADVECTION BEHIND
THE COLD FRONT WHICH WILL BE EAST OF THE AREA BY EARLY MONDAY. 850
MB TEMPS SHOULD DIP TO AROUND NEG 8 ON MONDAY WITH WITH A WNW FLOW
LIKELY LEADING TO SOME LAKE EFFECT ACTIVITY. THIS ACTIVITY WILL
LIKELY PERSIST INTO TUESDAY BEFORE ENOUGH RIDGING OCCURS TO SWITCH
THE WINDS. TEMPS SHOULD WARM ENOUGH DURING THE DAY FOR MIXED
PRECIP BUT MOSTLY SNOW IS EXPECTED MONDAY NIGHT. WILL TRY FOR DRY
WEATHER TUESDAY NIGHT.

HAVE USED A BLEND OF GUIDANCE TEMPS DURING THE PERIOD. MAY HAVE
GONE A LITTLE WARM FOR THE SNOWBELT BOTH MONDAY AND TUESDAY BUT
DON'T WANT TO STRAY TOO FAR FROM GUIDANCE.  

&

.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
ANOTHER STRONG STORM SYSTEM WILL BE TAKING SHAPE OVER THE GULF COAST 
STATES BY WEDNESDAY. THIS STORM SYSTEM WILL MOVE NORTHWARD NEAR THE 
SPINE OF THE APPALACHIAN MOUNTAINS. STILL SOME UNCERTAINTY AS TO 
WHICH SIDE OF THE MOUNTAINS THIS LOW WILL TRACK AT THIS TIME. THE 
TRACK WILL HAVE IMPLICATIONS ON HOW MUCH PRECIPITATION WILL OCCUR 
ACROSS NORTHERN OHIO AND NW PA. AT THIS POINT HAVE TRENDED WITH THE 
FURTHER WEST TRACK OF THE ECMWF. IN ANY EVENT IT WILL BE COOLER IN 
THE WAKE OF THE STORM SYSTEM BY FRIDAY WITH SOME LAKE EFFECT SNOWS 
DEVELOPING. WILL CONTINUE TO MONITOR THIS POTENTIAL THROUGH THE WEEK.

IF THE WESTERN TRACK DOES MATERIALIZE THEN SOME WARMER AIR WILL BE 
IN PLACE OVER THE REGION FOR WEDNESDAY INTO THURSDAY. CLOUD COVER 
AND ANY RAINFALL WILL LIMIT HIGHS BUT AT LEAST THE REGION WILL BE 
NEAR SEASONAL AVERAGES.

&&

.AVIATION /08Z SATURDAY THROUGH WEDNESDAY/...
THE CLOUDS WILL BE DECREASING FROM THE WEST SLOWLY AS HIGH
PRESSURE MOVES IN...THE DECREASE WILL NOT REACH CLE UNTIL 13Z. NOT
EXPECTING FOG TO DEVELOP AS THE WINDS SHOULD BE STRONG ENOUGH.
ELSEWHERE MAINLY MVFR CEILINGS UNTIL CONDITIONS IMPROVE SATURDAY
MORNING. NOT MUCH PRECIPITATION WILL OCCUR OVERNIGHT...JUST SPOTTY
DRIZZLE OR FLURRIES.

.OUTLOOK...MVFR LATE SUN INTO SUN NIGHT AND CONTINUE MON INTO
EARLY TUE FOR AT LEAST THE SNOWBELT BEFORE WIDESPREAD VFR RETURN
LATER TUE.

&&

.MARINE...
W TO NW WINDS CONTINUE TO FLOW ACROSS LAKE ERIE AS SURFACE HIGH 
PRESSURE BEGINS TO RIDGE NORTHWARD IN THE WAKE OF SURFACE LOW 
PRESSURE THAT IS MOVING OFF THE NEW ENGLAND COAST. STILL LOOKS LIKE 
THE SMALL CRAFT ADVISORY WILL BE NEEDED FOR THE EASTERN HALF OF THE 
LAKE AS WINDS GRADUALLY DECREASE THROUGH THE DAY. WAVES OF 5 TO 7 
FEET WILL GRADUALLY SUBSIDE TO 3 TO 5 FEET THROUGH THE AFTERNOON. 
WINDS WILL BE LIGHT ENOUGH TONIGHT THROUGH SUNDAY TO ALLOW THE SMALL 
CRAFT ADVISORIES TO BE DOWN. HOWEVER AS THE FLOW RETURNS TO THE W 
AND NW SUNDAY NIGHT INTO MONDAY AS A COLD FRONT SWEEPS ACROSS LAKE 
ERIE. A SMALL CRAFT ADVISORY WILL ONCE AGAIN BE NEEDED AND WILL 
LIKELY CONTINUE INTO AT LEAST THE MIDDLE PORTION OF THE WEEK.  

&&
