AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
959 PM EDT TUE OCT 6 2009
.SYNOPSIS...
A COLD FRONT WILL SWEEP THROUGH THE LOWER GREAT LAKES REGION
TONIGHT...FOLLOWED BY COOL AND WINDY WEATHER ON WEDNESDAY. A WEAK
AREA OF HIGH PRESSURE WILL BUILD ACROSS THE AREA ON THURSDAY...BUT
WILL BE SHORT LIVED AS ANOTHER DISTURBANCE MOVES OUT OF THE CENTRAL
PLAINS AND INTO THE GREAT LAKES ON FRIDAY.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
SURFACE LOW PRESSURE WILL CONTINUE TO MOVE FROM THE NORTHERN GREAT
LAKES INTO SOUTHERN ONTARIO TONIGHT. THIS WILL ASSIST IN PUSHING
AN AREA OF RAINFALL QUICKLY ACROSS NORTHERN OHIO AND NW PA. THERE
WILL BE A LULL IN THE RAINFALL BETWEEN THIS AREA OF RAINFALL AND
THE COLD FRONT THAT IS LOCATED FROM EASTERN MICHIGAN INTO CENTRAL
INDIANA AT 02Z. SHOWERS ALONG THE FRONT WILL BE SCATTERED IN
NATURE. WINDS WILL INCREASE SIGNIFICANTLY IN THE WAKE OF THE COLD
FRONT. EXPECT WESTERLY WINDS TO INCREASE TO AT LEAST 20 TO 30 MPH
WITH GUSTS ATTEMPTING TO REACH 50 MPH...ESPECIALLY THE NORTHERN
HALF OF THE REGION. WILL KEEP THE WIND ADVISORY IN ITS CURRENT
CONFIGURATION WITH THIS UPDATE. OTHERWISE ONLY MINOR CHANGES HAVE
BEEN MADE TO THE GRIDS TO REFLECT CURRENT CONDITIONS.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY NIGHT/...
CYCLONIC FLOW ACROSS THE LAKES AND 850MB TEMPS OF +2C WILL ALMOST
CERTAINLY YIELD LAKE EFFECT RAIN SHOWERS DOWNWIND OF THE LAKE ON
WEDNESDAY. ELSEWHERE THINGS SHOULD DRY OUT FAIRLY QUICKLY WITH A DRY
DAY IN STORE FOR THE WESTERN AND SOUTHERN COUNTIES. THE FLOW QUICKLY
TURNS SOUTHWESTERLY WEDNESDAY NIGHT AS A WEAK RIDGE BUILDS ACROSS
THE AREA SO I DRIED THINGS OUT QUICKLY ACROSS THE NORTH. THE FIRST
PART OF THURSDAY SHOULD BE DRY ACROSS THE ENTIRE AREA BUT THE
PATTERN ALOFT IS FAIRLY PROGRESSIVE AND ANOTHER SHORTWAVE WILL
QUICKLY APPROACH THURSDAY EVENING. AT THIS POINT THERE ARE SOME
DIFFERENCES IN THE MODELS...WITH THE EUROPEAN NAM AND CANADIAN ALL
SHOWING AN OPEN WAVE/FRONT MOVING THROUGH ON FRIDAY. MEANWHILE THE
GFS DEVELOPS A CLOSED LOW ACROSS INDIANA...COMPLETE WITH A WARM
FRONT AND TRAILING COLD FRONT AND COPIOUS AMOUNTS OF PRECIP. I
DEFINITELY THINK IT WILL RAIN THURSDAY NIGHT AND FRIDAY BUT I THREW
OUT THE GFS SOLUTION AND STUCK CLOSE TO THE OTHERS. CATEGORICAL POPS
ON FRIDAY TAPERING OFF FROM WEST TO EAST FRIDAY NIGHT.
TEMPS THROUGH THE WEEK WILL BE A BIT CHILLY AND A FEW DEGREES BELOW
NORMAL ESPECIALLY WEDNESDAY BEHIND THE FRONT. SHOULD SEE A BIT OF AN
INCREASE THURSDAY UNDER HIGH PRESSURE AND MAYBE EVEN A DEGREE OR TWO
MORE ON FRIDAY AHEAD OF THE COLD FRONT BUT THIS WILL BE SHORT LIVED
WITH COOLER TEMPS ON THE WAY THIS WEEKEND.
&&
.LONG TERM /SATURDAY THROUGH TUESDAY/...
A LOT OF HIGH PRESSURE FOR THE EXTENDED PERIOD. HIGH PRESSURE
BUILDING IN FOR SATURDAY AND SUNDAY...GFS...ECMWF...DIGEX AND GEM
ALL AGREE. WITH SO MUCH RIDGING THERE MAY NOT BE THAT MUCH LAKE
EFFECT PRECIPITATION...BACKED OFF ON THE POPS A LITTLE. 850 MB
TEMPERATURES VARY...WENT A LITTLE COOLER THAN GUIDANCE. FROST WILL
DEFINITELY BE A POSSIBILITY...TOO FAR AWAY AT THIS TIME TO MENTION
IN ZONES/GRIDS.
A WEAK TROF WILL MOVE THROUGH SUNDAY NIGHT THROUGH MONDAY EVENING
AND MAY CAUSE A THREAT OF SHOWERS. THE 850 MB TEMPERATURES ARE COOL
BUT AT THIS TIME THE BOUNDARY LAYER IS STILL WARM...1000 TO 850 MB
THICKNESS INDICATES LIQUID...SO WILL JUST KEEP IT RAIN SHOWERS. HIGH
PRESSURE BUILDS IN QUICKLY TUESDAY...SO MAY NOT BE MUCH LAKE EFFECT
SHOWERS.
FOR MONDAY AND TUESDAY HPC GUIDANCE NUMBERS SEEM TO LINE UP WELL
WITH LOCAL SCHEMES AND ENSEMBLE MOS GUIDANCE VALUES. MADE ONLY MINOR
CHANGES.
&&
.AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
ITS GOING TO BE A ROUGH NIGHT. A WARM FRONT IS CURRENTLY MOVING
NE ACROSS THE AREA. HAVE ALREADY SEEN SOME IFR VSBYS/CIGS IN NW
OH. EXPECT IFR WEATHER TO OVERSPREAD THE REMAINDER OF THE TAF SITES
THIS EVENING. BEST CHANCES FOR PERSISTENT LOW CIGS WILL BE AT
KMFD. COLD FRONT STILL ON TRACK TO MOVE ACROSS THE AREA OVERNIGHT.
EXPECT CIGS AND VSBYS TO REBOUND BEHIND THE FRONT. PRECIP IS
CURRENTLY SCATTERED BUT EXPECT IT TO BECOME MORE WIDESPREAD THE
NEXT COUPLE OF HOURS. EXPECT IFR CONDITIONS TO QUICKLY DEVELOP
WHERE THE HEAVIER SHRA DEVELOP. THE OTHER STORY FOR THE PERIOD
WILL BE THE WINDS. ALREADY SEEING SOUTH GUSTS TO 25 TO 30 KNOTS IN MANY
AREAS. WINDS WILL BECOME SW ALL AREAS BY 03Z AND THEN WEST BEHIND
THE COLD FRONT. WE WILL LIKELY SEE A FEW GUSTS TO 40 KNOTS FROM
LATE TONIGHT THROUGH WEDNESDAY MORNING. WINDS SHOULD GRADUALLY
DIMINISH AFTER 15Z WED. EXPECT SKIES TO CLEAR FROM WEST TO EAST
WED AFTERNOON.
.OUTLOOK...NON VFR CONDITIONS DEVELOPING LATE THURSDAY NIGHT AND
CONTINUING INTO FRIDAY NIGHT WITH RAIN AND CLOUDS. VFR TRYING TO
RETURN FOR THE WEEKEND.
&&
.MARINE...
MODELS IN GOOD AGREEMENT MOVING LOW....NOW OVER CENTRAL WISCONSIN
ACROSS CENTRAL LAKE MICHIGAN TONIGHT AND INTO SOUTHWESTERN QUEBEC BY
DAYBREAK. AS A RESULT SOUTH FLOW OVER THE LAKE WILL INCREASE THIS
EVENING AHEAD OF THE DEEPENING LOW. WIND WILL REALLY RAMP UP WITH
FRONTAL PASSAGE TONIGHT FROM WEST TO EAST AND STRONGEST SURGE WILL
COME A FEW HOURS AFTER THE FRONT AS THE ISALLOBARIC SURGE PUSHES
ACROSS THE LAKE FROM WEST TO EAST. PUSHED GALE WARNING BACK TO 10 PM
AS YOU COULD SEE GALE FORCE WINDS OVER THE WESTERN BASIN BY 10 PM.
WINDS WILL DECREASE ON WEDNESDAY FROM WEST TO EAST AS HIGH PRESSURE
MOVES OVER THE LAKE...BUT IT WILL TAKE UNTIL EVENING FOR THE GALES
TO END ON THE EAST END OF THE LAKE.
STILL SOME MODEL DIFFERENCES IN THE STRENGTH AND TRACK OF THE NEXT
LOW PRESSURE SYSTEM ON FRIDAY. FORECAST IS BASED ON THE MAJORITY OF
THE MODELS WITH A RELATIVELY WEAK SURFACE LOW TRACKING ACROSS THE
EASTERN GREAT LAKES. THE OPERATIONAL GFS CONTINUES TO PUT A STRONGER
LOW ACROSS THE CENTRAL GREAT LAKES WHICH WOULD RESULT IN HIGHER
WINDS/WAVES. TROUGH ALOFT DEEPENS AND COLD ADVECTION INCREASES OVER
THE WEEKEND AND EXPECT THE LAKE TO CONTINUE TO BE QUITE CHOPPY.
