AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
944 AM EST SUN DEC 23 2007
.SYNOPSIS...
DEEP LOW PRESSURE OVER THE WESTERN GREAT LAKES WILL PUSH A STRONG
COLD FRONT ACROSS THE AREA TODAY. STRONG SOUTH WINDS AND WARM
EARLY MORNING TEMPERATURES WILL BE REPLACED BY GUSTY SOUTHWEST
WINDS AND FALLING TEMPERATURES. A TROUGH OF LOW PRESSURE WILL
ROTATE SOUTHEAST ACROSS THE EASTERN GREAT LAKES TO NIGHT AND
MONDAY. HIGH PRESSURE WILL MOVE TO THE OHIO VALLEY BY CHRISTMAS
DAY BRINGING QUIET WEATHER.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TREMENDOUS COLD ADVECTION CONTINUES ACROSS THE AREA. POST FRONTAL
TEMPS ACROSS CENTRAL INDIANA ARE ALREADY IN THE LOW TO MID 20S
WHILE TEMPS AHEAD OF THE FRONT NEAR CANTON AND YOUNGSTOWN ARE
CLIMBING THROUGH THE MID 50S. FRONT WILL CONTINUE TO MARCH
EASTWARD THIS MORNING AND SHOULD BE THROUGH THE ENTIRE FORECAST
AREA BY 18-20Z. WINDS STILL THE MAIN STORY THIS MORNING AND WILL
MAINTAIN HIGH WIND WARNING HEADLINES AT ALL LOCATIONS. GUSTS TO
60MPH ALREADY BEING REPORTED AND SEE NO REASON WHY WINDS WILL
DIMINISH ANY TIME SOON.
ALL PRECIP HAS ENDED BEHIND THE FRONT AND HAVE THEREFORE MADE SOME
CHANGES TO THE POPS. WILL DRY OUT THE WESTERN TIER COUNTIES AND
EVENTUALLY DRY OUT ALL SITES BY THIS AFTERNOON. COULD SEE SOME
ADDITIONAL PRECIP DEVELOP DOWNWIND OF LAKE ERIE LATE THIS
AFTERNOON AND WILL KEEP A LOW CHANCE POP IN PLACE FOR
ASHTABULA/ERIE/CRAWFORD COUNTIES. ELSEWHERE RAIN WILL STOP BY
EARLY AFTERNOON BUT WINDS WILL CONTINUE THROUGH THE OVERNIGHT
HOURS.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
DO NOT EXPECT SIGNIFICANT SNOW WITH UPPER LOW/WRAP AROUND TONIGHT
INTO MONDAY ALTHOUGH A COATING OF SNOW POSSIBLE JUST ABOUT
ANYWHERE WITH THE BEST CHANCE ACROSS THE NORTHERN COUNTIES AND
HIGHER TERRAIN. PROBABLY NOT ENOUGH FOR A WHITE CHRISTMAS.
SOUTHWEST WIND IN THE BOUNDARY LAYER NOT FAVORABLE FOR LAKE EFFECT
SNOW TONIGHT. THE PASSAGE OF UPPER LOW COULD SHIFT WIND ONSHORE
JUST ENOUGH ON MONDAY FOR AN INCREASE IN LAKE EFFECT SNOW SHOWERS
ALONG THE LAKESHORE EAST OF CLEVELAND AND ESPECIALLY ACROSS ERIE
COUNTY PA ALTHOUGH BY THE TIME THE WIND BECOMES MORE WESTERLY AND
ONSHORE...SUBSIDENCE PROGGED TO DEVELOP WITH INVERSION LOWERING
AND DO NOT ANTICIPATE ANY WIDESPREAD HEAVY SNOW SHOWERS EVEN ALONG
THE LAKE SHORE. SOME PASSING LOCALIZED HEAVIER SNOW SHOWERS
POSSIBLE. NOT SURE WHY GFS MOS MAX TEMP GUIDANCE IS SO WARM MONDAY
WITH UPSTREAM TEMPS SO COLD. WILL FORECAST MAX TEMPS A CATEGORY
OR TWO BELOW GUIDANCE MONDAY...GENERALLY UPPER 20S TO MID 30S FAR
SOUTH.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
EXTENDED PORTION OF THE FORECAST LOOKS TO BEGIN ON A QUIET NOTE AS
HIGH PRESSURE BUILD IN ACROSS THE LOWER GREAT LAKES REGION. COULD
START OFF ON TUESDAY WITH SOME LINGERING LAKE EFFECT SNOW ACROSS
EXTREME NE OH/NW PA BUT STRONG SUBSIDENCE AND DRY AIR ALOFT WILL
LIKELY LIMIT SNOW TO THE EARLY PART OF THE DAY. WILL GO WITH A DRY
FORECAST FROM TUESDAY AFTERNOON ONWARD THROUGH THE DAY ON WEDNESDAY
AS HIGH PRESSURE TAKES HOLD OVER THE AREA.
BEGIN TO SEE SOME DIFFERENCES BETWEEN THE EURO AND GFS MODELS FROM
WEDNESDAY NIGHT ONWARD. BOTH MODELS SHOW A WAVE MOVING THROUGH THE
FORECAST AREA WEDNESDAY NIGHT INTO THURSDAY MORNING BUT THE GFS IS
MUCH FASTER AND TRIES TO DRY THINGS OUT THURSDAY AFTERNOON.
MEANWHILE THE EUROPEAN DEVELOPS A SECONDARY AREA OF LOW PRESSURE AND
MOVES IT THROUGH THE LOWER OHIO VALLEY...KEEPING PRECIP AROUND
THROUGH THE END OF THE WEEK. WHILE THIS IS THE MORE PESSIMISTIC
SOLUTION...IT DOES HAVE THE SUPPORT OF THE CANADIAN MODEL AND HAVE
THEREFORE STUCK CLOSER TO IT. THAT BEING SAID...IT IS ALSO THE
WARMER SOLUTION AND THEREFORE PRECIP FROM THURSDAY ONWARD WILL
LIKELY BE A MIX OF RAIN AND SNOW OR ALL RAIN. THE SYSTEM ON
THURSDAY WILL ESSENTIALLY ACT AS A WARM FRONT AND TEMPS BY THE
END OF THE WEEK SHOULD BE ABOVE NORMAL.
&&
.AVIATION /15Z SUNDAY THROUGH THURSDAY/...
COLD FRONT AND THIN CONVECTIVE LINE MARCHING EASTWARD THIS
MORNING. WINDS HAVE GUSTED UPWARDS OF 50 KTS WITH THIS FEATURE. IT
IS EXPECTED TO STAY FAIRLY INTACT AS IT MOVES EASTWARD WITH OR
SLIGHTLY AHEAD OF THE FRONT. HAVE CB AT TOL/FDY...BUT CB MAY NEED
TO BE ADDED EASTWARD IF WE CAN GET SOME LIGHTNING WITH THIS LINE.
WINDS WILL SHIFT TO THE SW AFTER THE FRONT. GUSTS WILL STILL
REMAIN HIGH THROUGHOUT THE DAY AND INTO THE EVENING...UP AROUND 40
KNOTS. THERE IS A SIGNIFICANT AMOUNT OF DRYING IMMEDIATELY BEHIND
THE FRONT SO AS TEMPERATURES FALL PRECIP WILL END. A 20 DEGREE
TEMPERATURE DROP CAN BE EXPECTED WITH IN A COUPLE HOUR PERIOD.
ONCE THE COLD AIR IS HERE...THERE MAY BE SCATTERED FLURRIES BUT
FOR NOW DO NOT HAVE IN TAFS. BETTER CHANCE FOR SNOW SHOWERS WOULD
TONIGHT AS WRAP AROUND MOISTURE MOVES ACROSS. WINDS WILL STILL BE
GUSTY OVERNIGHT...ESPECIALLY ALONG/NEAR THE LAKESHORE.
AS FAR AS CEILINGS GO...A PERIOD OF MVFR WITH AND BEHIND THE
FRONT...THEN SOME DRYING/MIXING SHOULD ALLOW FOR VFR CEILINGS TO
RETURN LATER IN THE AFTERNOON. WITH THIN CONVECTIVE LINE AND ANY
OTHER ENHANCED ECHOS...TEMPORARILY DIPS TO IFR POSSIBLE BUT OF
SHORT DURATION AND DID NOT EVEN BOTHER WITH A TEMPO GROUP. MVFR
POSSIBLE AGAIN TONIGHT WITH WRAP AROUND MOISTURE.
OUTLOOK...LAKE EFFECT SNOW SHOWERS MAY AFFECT ERI SUNDAY
NIGHT/MONDAY. AS THE WINDS SHIFT TO MORE OF A WESTERLY DIRECTION
THE BANDS MAY AFFECT YNG AND PERHAPS CLE MONDAY. OTHERWISE...HIGH
PRES BUILDS IN AND VFR CONDITIONS SHOULD PREVAIL THROUGH THU. A
WEAK COLD FRONT SLIDE THROUGH WED/THU TIME FRAME WITH LITTLE
TROUBLE.
&&
.MARINE...
STRONG COLD FRONT STILL PROGGED TO SWEEP ACROSS THE LAKE THIS
MORNING/AFTERNOON. VERY IMPRESSIVE PRESSURE RISES BEHIND THE FRONT
THIS AFTERNOON SHOULD EASILY BRING WINDS UP TO GALES/STORM BY
EARLY AFTERNOON. BUFR DATA SUGGESTING SOME OF THE STRONGEST WINDS
SUNDAY NIGHT WITH THE CONTINUED COLD AIR ADVECTION...IN ADDITION
TO IMMEDIATELY BEHIND/WITH THE FRONT TODAY. THEREFORE STORMS UP
FOR LAKE ERIE FOR TODAY AND TONIGHT. GALES TO FOLLOW AS WINDS
SLOWLY COME DOWN MONDAY. TUESDAY WILL SEE HIGH PRESSURE BUILD
ACROSS THE LAKE WITH WINDS GRADUALLY BACKING AND DIMINISHING TO 5
TO 15KTS. LOW PRESSURE WILL DEVELOP WEST OF THE REGION ON
WEDNESDAY WHICH WILL LIKELY PULL THE WINDS AROUND OUT OF THE
SOUTHEAST BUT WEAK NATURE OF THE LOW SHOULD KEEP WINDS FROM
GETTING MUCH ABOVE 10-20KTS. MUCH OF THE SAME FOR THURSDAY AS
WELL.
