AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
357 AM EST SAT FEB 13 2016

.SYNOPSIS...
AN ARCTIC COLD FRONT WILL CONTINUE TO MOVE SOUTH OF THE AREA
USHERING IN MUCH COLDER AIR TO THE REGION. A LARGE AREA OF HIGH
PRESSURE WILL MOVE EAST ACROSS THE GREAT LAKES AND OHIO VALLEY
TODAY AND TONIGHT. A WEAK LOW PRESSURE SYSTEM WILL MOVE EAST INTO
THE TENNESSEE VALLEY BY MONDAY MORNING AND THEN TO PENNSYLVANIA
AND NEW YORK STATE BY MONDAY NIGHT. A RIDGE OF HIGH PRESSURE WILL
BUILD NORTHEAST ACROSS THE LOCAL AREA TUESDAY FOLLOWED BY YET
ANOTHER AREA OF LOW PRESSURE TUESDAY NIGHT.
&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
ARCTIC COLD FRONT SLIPPED SOUTH OF THE AREA EARLY THIS MORNING
WITH MUCH COLDER AIR TO FOLLOW. INITIAL COLD FRONT LAST EVENING
DROPPED TEMPERATURES INTO THE TEENS AND THIS SECONDARY FRONT
FORCED TEMPERATURES TO FALL INTO THE SINGLE DIGITS. AS THE COLD
AIR SETTLES IN OVER THE AREA TODAY...I DOUBT WE WILL SEE MUCH IN
THE WAY OF INCREASE IN TEMPERATURES FOR HIGHS TODAY. THIS WILL BE
A WAIT AND SEE ON WHETHER I HAVE TEMPERATURES TOO WARM IN THE
WEST. GUT FEELING NOW IS THEY WILL STRUGGLE TO GET ABOVE 10 FOR A
HIGH TODAY. GUSTY WINDS WILL ALSO CAUSE DANGEROUS WIND CHILLS AND
THEREFORE WIND CHILL ADVISORY REMAIN IN EFFECT.

AS FAR AS THE LAKE EFFECT SNOW GOES...BANDS HAVE DEVELOPED FROM
THE NORTH TO NORTHWEST. ONE BAND IS OVER CLEVELAND HOPKINS AIRPORT
INTO SUMMIT AND STARK COUNTIES. A SECOND BAND OF LIGHTER INTENSITY
WAS EXTENDING SOUTHEAST INTO SOUTHERN LORAIN COUNTY. A LAKE HURON
CONNECTION EXTENDED A BAND ACROSS ERIE COUNTY IN PENNSYLVANIA.
NARROW BANDS OF HEAVIER SNOW CAN BE EXPECTED WITH THESE SNOW
BANDS BUT THEY ARE MOVING SLIGHTLY. THIS WILL SPREAD OUT THE SNOW
ACCUMULATIONS OVER A WIDER AREA RATHER THAN A VERY NARROW BAND.
WILL HOLD ON TO THE WARNINGS/ADVISORIES FOR THE SNOW THROUGH THE
DAY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
UPPER LEVEL TROUGH OVER THE FORECAST AREA WILL MOVE OFF TO THE
EAST ALLOWING A VERY WEAK RIDGE OF HIGH PRESSURE TO BUILD EAST
OVER THE REGION. THIS UPPER LEVEL RIDGE WILL FORCE HIGH PRESSURE
AT THE SURFACE TO MOVE EAST OF THE AREA TODAY.

ANOTHER TROUGH WILL DIVE INTO THE FORECAST AREA ALOFT SIGNALING A
WAVE OF LOW PRESSURE TO MOVE EAST NORTHEAST ACROSS THE AREA
MONDAY. THIS LOW PRESSURE SYSTEM WILL BRING ANOTHER ROUND OF
LIGHT SNOW TO THE ENTIRE FORECAST AREA MONDAY INTO MONDAY NIGHT.
SNOW ACCUMULATIONS BETWEEN 1 AND 3 INCHES AT MOST IS EXPECTED WITH
THIS SYSTEM.

SOME LINGERING LIGHT SNOW IS EXPECTED MONDAY NIGHT AS THE LOW
PRESSURE SYSTEM PULLS OUT TO THE EAST.

TEMPERATURES BY MONDAY SHOULD BEGIN TO MODERATE AS SOME WARM AIR
ADVECTION BEGINS TO TAKE PLACE. HOWEVER...COLD ARCTIC AIR WILL
REMAIN IN PLACE THROUGH SUNDAY. LOWS SUNDAY MORNING WILL BE COLDER
THAN THIS MORNING AS HIGH PRESSURE SETTLES IN OVER THE LOCAL AREA.
THIS SHOULD BE THE EXTENT OF THE ARCTIC AIR INVASION AS SOME WARM
AIR ADVECTION BEGINS TO TAKE PLACE ESPECIALLY SUNDAY NIGHT INTO
MONDAY.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
NOT MANY CHANGES TO THE LONG TERM THIS MORNING. A COUPLE SYSTEMS
WILL IMPACT THE AREA DURING THE PERIOD.  THE MODELS CONTINUE TO SHOW
DIFFERENCES AND HAVE USED A BLEND OF THE GUIDANCE AGAIN TODAY.  LOW
PRESSURE WILL BE OFF TO THE SOUTHEAST AT DAYBREAK TUESDAY.  THE BACK
EDGE OF THE PRECIP SHIELD ASSOCIATED WITH THIS LOW WILL BE ACROSS
THE AREA AT THE START OF THE DAY.  WILL TRY TO DRY THINGS OUT BY
MIDDAY.  THE NEXT SYSTEM WILL RIGHT ON IT`S HEALS AND WILL LIKELY
SEE MORE LIGHT SNOW TUESDAY NIGHT INTO WEDNESDAY.  THIS SYSTEM WILL
BE A FAST MOVER AND BY MIDDAY WEDNESDAY IT SHOULD AGAIN BE DRY. HIGH
PRESSURE WILL MOVE TO THE EAST THE SECOND HALF OF THE WEEK ALLOWING
WARM SOUTHERLY WINDS TO RETURN.  THE AREA WILL BE BACK ABOVE NORMAL
BY THURSDAY AND REALLY WARM ON FRIDAY.  WILL LIKELY SEE MORE PRECIP
BY THE END OF THE PERIOD.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
ROBUST SNOW SHOWERS CONTINUE ACROSS NORTHEAST OHIO AT TAF
ISSUANCE. DRIER AIR IS SEEN APPROACHING CLEVELAND FROM THE NORTH
AND SNOW SHOWERS WILL BECOME MORE CONFINED TO AREAS DOWN WIND OF
LAKE HURON BY LATE TONIGHT. THESE SNOW SHOWERS WILL IMPACT YNG AND
ERI AT TIMES OVERNIGHT INTO SATURDAY. SCATTERED SNOW SHOWERS WILL
DEVELOP AGAIN ON SATURDAY AFTERNOON AND WILL OCCASIONALLY IMPACT
ALL TERMINALS. CLOUDS WILL RANGE FROM VFR TO MVFR EXCEPT IN NW
OHIO WHERE CLOUDS HAVE CLEARED OUT. CLOUDS WILL RETURN TO THE
WESTERN TERMINALS IN THE MORNING. NORTHWEST WINDS WILL BE BREEZY
WITH GUSTS TO 20-25 KNOTS.

OUTLOOK...NON VFR IN SNOW SHOWERS THROUGH SATURDAY NIGHT MAINLY
FOR THE SNOWBELT OF EXTREME NE OH/NW PA. NON VFR MONDAY AND
MONDAY NIGHT IN LIGHT SNOW ESPECIALLY NE OH/NW PA.

&&

.MARINE...
NOT MANY CHANGES TO THE MARINE PACKAGE THIS MORNING.
WINDS CONTINUE TO BLOW TO AROUND 30 KNOTS ON THE LAKE.  SPEEDS
SHOULD BE PEAKING AND EXPECT THE FLOW TO GRADUALLY DIMINISH TODAY.
BY LATE TONIGHT THE FLOW WILL BE UNDER 10 KNOTS AND THE THREAT FOR
ICING WILL BE OVER.  HIGH PRESSURE OVER THE NORTHERN PLAINS THIS
MORNING WILL BE OVER OHIO AT DAYBREAK SUNDAY.  THE SURFACE RIDGE
WILL PUSH EAST OF THE LAKE DURING THE DAY WITH SOUTHERLY FLOW
DEVELOPING.  A PAIR OF LOWS WILL IMPACT THE REGION THE FIRST HALF OF
THE WEEK WITH WINDS BECOMING WESTERLY ON THE BACKSIDE OF THESE
SYSTEMS.  IT DOES NOT LOOK LIKE SPEEDS WILL BE HIGH ENOUGH TO
NECESSITATE ANY HEADLINES.  GIVEN THE COLD WEATHER EXPECTED THE NEXT
36 HOURS EXPECT THERE TO BE A LOT OF ICE ON THE LAKE AGAIN BY EARLY
MONDAY.
