AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
644 PM EST THU DEC 25 2014

.SYNOPSIS...
HIGH PRESSURE WILL RIDGE INTO THE REGION FROM THE MIDDLE ATLANTIC
STATES TONIGHT INTO FRIDAY. THE HIGH WILL THEN MOVE OFF THE COAST
ALLOWING LOW PRESSURE TO MOVE INTO THE CENTRAL GREAT LAKES ON
SATURDAY. THE LOW IS EXPECTED TO REACH WESTERN QUEBEC SATURDAY
NIGHT WITH A COLD FRONT MOVING ACROSS THE AREA.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
UPDATE...WRN TWO THIRDS OF NRN INDIANA HAVE CLEARED OUT WITH
DECREASING CLOUDS STILL EXPECTED TO GET INTO WRN COUNTIES AROUND
3Z OR SO. HAVE ADJUSTED CLOUDS TO REFLECT CLEARING FROM WEST TO
EAST ACROSS THE AREA THROUGH THE OVERNIGHT.


ORIGINAL...HIGH PRESSURE WILL RIDGE INTO THE AREA FROM THE MIDDLE
ATLANTIC STATES TONIGHT. CLOUDS HAVE BEEN ATTEMPTING TO THIN ALL
DAY WITH THE CLEARING LINE ABOUT TO ENTER EASTERN INDIANA. EXPECT
TO SEE THE CLOUD COVER TO CONTINUE TO DECREASE FROM WEST TO EAST
THROUGH THE NIGHT.

IN ANY EVENT IT WILL BE COOLER OVERNIGHT WHEN COMPARED TO THIS
MORNINGS LOW. ALL LOCATIONS SHOULD BE WITHIN A COUPLE DEGREES OF
30. IF WE CAN CLEAR SOON ENOUGH ACROSS THE WEST TEMPERATURES MAY
NEED TO BE NUDGED DOWN SLIGHTLY.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY NIGHT/...
DRY CONDITIONS WILL CONTINUE INTO FRIDAY NIGHT AS HIGH PRESSURE
PERSISTS OVER THE MIDDLE ATLANTIC COAST. AS THE HIGH MOVES OUT
INTO THE ATLANTIC IT WILL ALLOW LOW PRESSURE TO MOVE INTO THE
CENTRAL GREAT LAKES BY SATURDAY AFTERNOON. SHOWERS SHOULD BEGIN TO
SPILL INTO NW OHIO SATURDAY AFTERNOON AS A COLD FRONT GETS CLOSER.
THE REMAINDER OF THE REGION SHOULD SEE SHOWERS SATURDAY NIGHT AS
THE LOW LIFTS NORTHEASTWARD INTO WESTERN QUEBEC AND DRAGS THE COLD
FRONT EASTWARD WITH IT. AT THIS POINT IT APPEARS THE PRECIPITATION
WILL REMAIN LIQUID. HOWEVER COLDER AIR WILL SPILL INTO NW OHIO
SATURDAY NIGHT AFTER MIDNIGHT AND MAY ALLOW ANY REMAINING SHOWERS
TO BECOME SNOW SHOWERS. THIS TRANSITION TO SNOW SHOULD SPREAD
EASTWARD ON SUNDAY BUT LOOKS TO OCCUR AS THE PRECIPITATION IS
ENDING. SO WITH THAT SAID IT APPEARS ANY SNOWFALL ACCUMULATIONS
WILL BE LIGHT TO NONEXISTENT.

FRIDAY WILL SEE WARMER CONDITIONS WITH HIGHS BACK INTO THE MIDDLE
AND UPPER 40S FOR DAYTIME HIGHS. INCREASING CLOUD COVER FRIDAY
NIGHT SHOULD KEEP TEMPERATURES ABOVE FREEZING FRIDAY NIGHT.
CONTINUED WARM ADVECTION ON SATURDAY WILL BOOST HIGHS TO WITHIN A
COUPLE DEGREES OF 50 AT MOST LOCATIONS. COOLER IN THE WAKE OF THE
FRONT ON SUNDAY WITH HIGHS BACK INTO THE MIDDLE TO UPPER 30S.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
LONG TERM TRENDING TOWARD TROUGHINESS IN THE EAST THAT WILL PERSIST
THROUGH THE PERIOD. THIS WILL TRANSLATE INTO WHAT APPEARS TO BE A
TROUGH OF LOW PRESSURE THAT SLOWLY SAGS SOUTH ACROSS THE AREA LATE
TUESDAY INTO WEDNESDAY IN THE WAKE OF A SURFACE RIDGE OF HIGH
PRESSURE. THE TROUGH WILL HAVE LIMITED MOISTURE ASSOCIATED WITH IT
AND MAY BE ENHANCED BY LAKE MOISTURE. WILL INTRODUCE A BROAD MINIMAL
CHANCE FOR SOME LIGHT SNOW SHOWERS MONDAY THROUGH TUESDAY AND SOME
LAKE EFFECT IN THE NORTHEAST TUESDAY NIGHT. FAIR WEATHER RETURNS
WEDNESDAY INTO WEDNESDAY NIGHT. ANOTHER STRONGER COLD FRONT WILL
SLIDE SOUTH INTO THE REGION BY THURSDAY AND BRING WITH IT COLDER AIR
AND A CHANCE FOR SOME MORE SNOW SHOWER ACTIVITY BY THURSDAY EVENING.
TEMPERATURES THROUGH THE PERIOD TRENDING COLDER AND WILL ADJUST
TEMPERATURES ACCORDINGLY.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
THE MVFR CEILINGS WILL CONTINUE TO CLEAR FROM SOUTHWEST TO
NORTHEAST TONIGHT AS THE SURFACE RIDGE CROSSES THE AREA. VFR
FRIDAY WITH PATCHES OF HIGH CLOUDS. MVFR LOW CLOUDS MAY REACH KTOL
BY THE END OF THE DAY FRIDAY BUT MAY NOT MAKE MUCH PROGRESS ANY
FARTHER EAST UNTIL LATER SATURDAY.

.OUTLOOK...NON-VFR LATE SATURDAY THROUGH SUNDAY. NON-VFR MAINLY
OVER NE OH/NW PA MONDAY...THEN OVER THE ENTIRE AREA AGAIN TUESDAY.

&&

.MARINE...
WINDS STILL TOUCHING LOWER 30S IN SOME PLACES ON THE EASTERN HALF OF
THE LAKE BUT WILL GRADUALLY DIMINISH OVERNIGHT. WIND SPEEDS AND WAVE
HEIGHTS STILL WARRANT SMALL CRAFT ADVISORIES TO REMAIN IN EFFECT
FROM THE ISLANDS EAST. WILL DROP SMALL CRAFT ADVISORY WEST OF THE
ISLANDS AS WINDS AND FETCH HAVE DIMINISHED IN THAT AREA. ONCE WINDS
DIMINISH TOMORROW...THEY WILL BE FAIRLY QUIET THROUGH SATURDAY BUT A
POSSIBILITY FOR ANOTHER SMALL CRAFT ADVISORY OVER THE EXTREME EAST
EXISTS FOR SUNDAY. THIS EVENT SHOULD BE BRIEF AS WINDS DIMINISH
SUNDAY AFTERNOON AND EVENING. AS HIGH PRESSURE RIDGE BUILDS SOUTH
TUESDAY...GRADIENT ALSO INCREASES AND THEREFORE WILL LIKELY NEED
ANOTHER SMALL CRAFT ADVISORY FOR TUESDAY EAST TWO THIRDS.

&&
