Area forecast discussion, Nov 17, 3:47 AM EST, 12 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
347 AM EST THU NOV 17 2011
.SYNOPSIS...
A MUCH COLDER AIRMASS HAS ARRIVED AND WILL REMAIN IN PLACE THROUGH
THE END OF THE WEEK. ACCUMULATING LAKE EFFECT SNOWS ARE EXPECTED
THIS AFTERNOON THROUGH FRIDAY MORNING EAST OF BOTH LAKES ERIE AND
ONTARIO. OUTSIDE OF THE LAKE EFFECT IT WILL JUST BE CHILLY AND DRY
WITH SOME SUNSHINE. A SOUTHWEST FLOW OF MILDER AIR WILL ARRIVE FOR
THE WEEKEND WITH TEMPERATURES QUICKLY REBOUNDING TO ABOVE AVERAGE.
SATURDAY WILL BE DRY WITH HIGH PRESSURE NEARBY ACROSS THE MID
ATLANTIC STATES...THEN A COLD FRONT APPROACHES SUNDAY WITH A CHANCE
OF A FEW LIGHT SHOWERS.
&&
.NEAR TERM /THROUGH TONIGHT/...
08Z SURFACE ANALYSIS SHOWS THE SURFACE COLD FRONT MOVING OFF THE
EASTERN SEABOARD WITH MODERATE COLD AIR ADVECTION IN PLACE ACROSS
THE GREAT LAKES. MOISTURE CHANNEL IMAGERY SHOWS A BROAD LONGWAVE
TROUGH DIGGING INTO THE UPPER GREAT LAKES. RADAR IMAGERY IS DEVOID
OF ANY PRECIP...AND THAT SHOULD REMAIN THE CASE THROUGH MID MORNING.
SATELLITE IMAGERY DOES SHOW A WEALTH OF HIGH CLOUDS STREAMING NORTH
FROM THE OHIO VALLEY TO NEW ENGLAND IN ASSOCIATION WITH A STRONG
140+ KNOT UPPER LEVEL JET AND PLUME OF MID/HIGH LEVEL MOISTURE.
THESE HIGH CLOUDS WILL CONTINUE TO OVERSPREAD THE REGION THROUGH
EARLY THIS AFTERNOON BEFORE CLEARING LATE.
FROM A SYNOPTIC STANDPOINT THERE IS LITTLE TO SPEAK OF OVER THE NEXT
24 HOURS WITH JUST A CHILLY WNW FLOW IN PLACE. OUTSIDE OF LAKE
EFFECT AREAS THE HIGH CLOUDS WILL GIVE WAY TO SOME SUNSHINE LATER
THIS AFTERNOON...AND SKIES WILL JUST BE PARTLY CLOUDY OR EVEN MAINLY
CLEAR TONIGHT WITH COLD TEMPS.
MAIN CONCERN THEN WILL BE LAKE EFFECT. THE AIRMASS WILL BECOME
PLENTY COLD ENOUGH WITH 850MB TEMPS BOTTOMING OUT AROUND -10C
TONIGHT. WITH BOTH LAKES ERIE AND ONTARIO STILL IN THE LOWER 50S
THIS WILL YIELD MODERATE TO EXTREME INSTABILITY. THE MAIN LIMITING
FACTOR FOR THIS EVENT WILL BE THE LACK OF DEEPER SYNOPTIC SCALE
MOISTURE. THE DRY AIR WILL INITIALLY HURT LAKE EFFECT ORGANIZATION
AND INTENSITY TODAY...BUT A BRIEF WINDOW OF SOMEWHAT BETTER MOISTURE
THIS EVENING SHOULD ALLOW LAKE EFFECT TO FLOURISH AT LEAST BRIEFLY.
OFF LAKE ERIE...THE BOUNDARY LAYER FLOW IS INITIALLY QUITE SHEARED
THIS MORNING DUE TO THE PASSAGE OF A 700MB TROUGH AXIS. BY LATE
MORNING BOTH THE NAM/GFS ALIGN THE SURFACE-700MB FLOW DUE WEST. BY
THIS TIME COLD AIR WILL HAVE DEEPENED SUFFICIENTLY TO PRODUCE LAKE
INDUCED CAPE APPROACHING 1000J/KG AND EQUILIBRIUM LEVELS ABOVE 12K
FEET. SHORT TERM MESOSCALE MODEL GUIDANCE IS IN REASONABLE AGREEMENT
WITH THE EVOLUTION OF THE LAKE ERIE ACTIVITY THIS AFTERNOON...
ALTHOUGH PREFERENCE LIES WITH THE CANADIAN GEM WHICH PERFORMED QUITE
NICELY IN THE FIRST LAKE EFFECT EVENT OF THE SEASON LAST WEEK.
EXPECT DISORGANIZED LAKE EFFECT SNOW SHOWERS TO DEVELOP BY LATE
MORNING ACROSS THE WESTERN SOUTHERN TIER. THE BOUNDARY LAYER WILL
STILL BE A LITTLE MILD NEAR LAKE ERIE...SO SOME RAIN MAY MIX IN AT
FIRST. THE BOUNDARY LAYER FLOW WILL BACK A LITTLE THIS AFTERNOON
WITH THE APPROACH OF THE MAIN MID LEVEL TROUGH. THIS WILL PUSH LAKE
EFFECT NORTH TOWARDS THE BOSTON HILLS AND WYOMING COUNTY. EXPECT THE
BAND TO INTENSIFY LATE THIS AFTERNOON ACROSS SOUTHERN ERIE/WYOMING
AND THE FAR NORTHERN SECTIONS OF CHAUTAUQUA/CATTARAUGUS COUNTIES AS
LOW LEVEL CONVERGENCE AND MOISTURE INCREASE. THIS EVENING FLOW
QUICKLY BECOMES WEST AND EVENTUALLY WNW OVERNIGHT...SO EXPECT A WELL
ORGANIZED LAKE BAND TO PUSH SOUTH ACROSS THE SOUTHERN TIER THIS
EVENING THEN BREAK APART INTO SNOW SHOWERS OVERNIGHT WITH THE FOCUS
BECOMING UPSLOPE ON THE CHAUTAUQUA RIDGE. PEAK INTENSITY SHOULD BE
EARLY THIS EVENING WHEN LAKE INDUCED INSTABILITY AND MOISTURE
PEAK...WITH A SLOW DIMINISHING TREND OVERNIGHT.
AS FAR AS ACCUMS GO...EXPECT A QUICK 2-3 INCHES ACROSS THE BOSTON
HILLS INTO THE SOUTHWEST CORNER OF WYOMING COUNTY THIS AFTERNOON AND
EARLY EVENING. THE GREATEST ACCUMS SHOULD BE ACROSS THE HIGHER
TERRAIN OF CHAUTAUQUA/CATTARAUGUS COUNTIES WITH 4-6 INCHES IN THE
MOST PERSISTENT BANDS. THE ACCUMULATING SNOW SHOULD STAY JUST SOUTH
OF THE BUFFALO SOUTHTOWNS...ALTHOUGH IT MAY GET CLOSE FOR AN HOUR OR
TWO AROUND MID AFTERNOON. SNOWFALL RATES MAY BRIEFLY REACH 1 OR EVEN
2 INCHES PER HOUR THIS EVENING.
OFF LAKE ONTARIO...EXPECT A SIMILAR TREND AN HOUR OR TWO LATER.
SHEAR AND DRY AIR WILL AT FIRST PREVENT ANY ACTIVITY THIS MORNING.
BY LATE MORNING OR MIDDAY EXPECT DISORGANIZED LAKE EFFECT TO BEGIN
ACROSS THE TUG HILL REGION AS COLD AIR DEEPENS AND FLOW BECOMES WELL
ALIGNED FROM THE WEST. THE BOUNDARY LAYER WILL STILL BE A LITTLE
WARM...ESPECIALLY AT LOWER ELEVATIONS SO SOME RAIN MAY MIX IN AT
FIRST. THIS AFTERNOON THE FLOW BACKS MORE WSW WITH THE APPROACH OF
THE MAIN MID LEVEL TROUGH...WHICH WILL CARRY LAKE EFFECT TO THE
NORTHERN PORTION OF THE TUG HILL...AND LOCATIONS JUST SOUTH AND EAST
OF WATERTOWN.
EARLY THIS EVENING THE BOUNDARY LAYER FLOW QUICKLY SHIFTS TO WNW
WITH THE PASSAGE OF THE MID LEVEL TROUGH...CARRYING LAKE EFFECT
SOUTH ACROSS THE TUG HILL REGION AND INTO OSWEGO COUNTY. LAKE EFFECT
PARAMETERS IMPROVE WITH LAKE INDUCED CAPE OF 1100J/KG AND
EQUILIBRIUM LEVELS AROUND 18K FEET. THESE FAVORABLE CONDITIONS LAST
FOR A LONGER PERIOD THAN ON LAKE ERIE...WHICH WILL INCREASE THE
POTENTIAL FOR LARGER ACCUMULATIONS. EXPECT THE LAKE BAND TO SETTLE
ACROSS OSWEGO COUNTY OVERNIGHT...AND MAY OCCASIONALLY MAKE IT SOUTH
INTO PORTIONS OF NORTHERN CAYUGA AND EXTREME NORTHEAST WAYNE COUNTY
AS WELL. THERE IS SOME SUGGESTION IN THE MESOSCALE MODEL GUIDANCE
THAT AN UPSTREAM CONNECTION TO GEORGIAN BAY OR LAKE HURON MAY
DEVELOP FOR A FEW HOURS FROM 06-09Z FRIDAY...WHICH WOULD ENHANCE
HEAVY SNOW POTENTIAL. EXPECT SNOWFALL RATES TO POTENTIALLY REACH 2-3
INCHES PER HOUR TONIGHT DURING THE PEAK INTENSITY OF THE BAND. GIVEN
THE DEPTH OF THE MIXED LAYER...FAVORABLE CLOUD MICROPHYSICS...AND
EXPECTED SINGLE BAND CONFIGURATION MAY SEE SOME THUNDER/LIGHTNING IN
THIS BAND.
AS FAR AS ACCUMULATIONS GO...EXPECT THE GREATEST ACCUMULATIONS TO BE
ACROSS OSWEGO COUNTY WHERE THE BAND IS LIKELY TO HAVE THE GREATEST
RESIDENCE TIME...WITH AMOUNTS OF 6-9 INCHES IN THE MOST PERSISTENT
BANDS AWAY FROM THE LAKE ONTARIO SHORE. AS IS TYPICALLY THE CASE IN
NOVEMBER EVENTS...THE WARM LAKE WATERS WILL LIMIT ACCUMULATION RIGHT
ON THE LAKE. THE TUG HILL PORTION OF LEWIS COUNTY SHOULD SEE 4-6
INCHES. MAY SEE SOME MINOR 1-3 INCH ACCUMULATIONS ACROSS SOUTHERN
JEFFERSON COUNTY THIS AFTERNOON BEFORE THE BAND SHIFTS SOUTH. MAY
ALSO SEE SEVERAL INCHES IN NORTHERN CAYUGA COUNTY...AND SOME MINOR
ACCUMS IN FAR NORTHEAST WAYNE COUNTY. LAST BUT NOT LEAST...IN WNW
FLOW THE WESTERN SHORELINE OF LAKE ONTARIO FROM HAMLIN WEST TO
OLCOTT OFTEN GET BRUSHED WITH SOME MINOR LAKE EFFECT...WITH AN INCH
OR LESS EXPECTED THERE TONIGHT.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
AT THE START OF THE FORECAST PERIOD...EXPECT A WELL ORGANIZED BAND
OF LAKE EFFECT SNOW TO STILL BE IN PLACE EAST OF LAKE ONTARIO...WITH
WEAKER MORE DIFFUSE BANDS OFF LAKE ERIE IMPACTING THE SOUTHERN TIER.
ANOTHER COUPLE INCHES OF SNOW IS LIKELY WITH THE LAKE ONTARIO
BAND...BUT LITTLE OR NO ADDITIONAL ACCUMULATION IS EXPECTED EAST OF
LAKE ERIE.
HIGH PRESSURE RIDGING NORTH FROM THE MIDDLE ATLANTIC STATES ON
FRIDAY WILL CAUSE THE LOW LEVEL SHEAR TO INCREASE WHILE THE WINDS
BACK MORE TO THE SOUTHWEST. THE LOWER LEVELS OF THE ATMOSPHERE WILL
ALSO DRY OUT AS THE RIDGE NOSES INTO NEW YORK STATE. ALL THESE
FACTORS WILL CAUSE THE LAKE ONTARIO BAND TO WEAKEN AS IT DRIFTS
SLOWLY TO THE NORTH DURING THE MORNING AND AFTERNOON.
A RELATIVELY TIGHT GRADIENT BETWEEN THE SURFACE RIDGE AND LOW
PRESSURE THAT WILL BE LIFTING NORTH TOWARD THE UPPER MIDWEST WILL
RESULT IN BREEZY TO WINDY CONDITIONS ON FRIDAY. THE PRESENCE OF A 50
KNOT LOW LEVEL JET TRACKING JUST WEST OF THE LOWER LAKES COULD
RESULT IN WIND GUSTS UP TO 35 OR 40 MPH...ESPECIALLY ACROSS WESTERN
NEW YORK. THIS WILL PUT QUITE A CHILL IN THE AIR AS AFTERNOON
TEMPERATURES STRUGGLE TO GET ABOVE 40 DEGREES.
BRISK WINDS AND DRY CONDITIONS WILL CONTINUE FRIDAY NIGHT AS THE
HIGH REMAINS IN PLACE OVER THE MIDDLE ATLANTIC STATES.
ON SATURDAY...THE SURFACE HIGH WILL DRIFT OUT INTO THE ATLANTIC
WHILE A SECOND LOW LIFTS NORTHEAST FROM THE CENTRAL PLAINS. A
MODERATING SOUTHERLY FLOW BETWEEN THESE TWO SYSTEM WILL RESULT IN
SOME INCREASE IN MID AND HIGH LEVEL CLOUDS AS THE DAY WEARS ON.
WHILE TEMPERATURES WILL WARM TO ABOUT 50 DEGREES...A MODEST
SOUTHERLY WIND WILL STILL BE IMPACTING THE AREA.
SATURDAY NIGHT...THE CENTRAL PLAINS LOW IS FORECAST TO TRACK
NORTHEAST ACROSS THE CENTRAL GREAT LAKES AND SETTLE JUST SOUTH OF
JAMES BAY BY SUNDAY MORNING. INCREASING LOW LEVEL MOISTURE AHEAD OF
A TRAILING COLD FRONT WILL RESULT IN A FEW SHOWERS LATER SATURDAY
NIGHT. THE INCREASE IN CLOUD COVER AND PERSISTENT SOUTHERLY WINDS
WILL KEEP TEMPERATURES FAIRLY MILD SATURDAY NIGHT.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
ON SUNDAY...THE AFOREMENTIONED LOW WILL CONTINUE TO MOVE EAST ACROSS
SOUTHERN QUEBEC AND DRAG ITS TRAILING COLD FRONT EAST ACROSS THE
CWA. A FEW MORE RAIN SHOWERS WILL ACCOMPANY THE FRONTAL PASSAGE.
FOLLOWING THE PASSAGE OF THE COLD FRONT...A NORTHWESTERLY FLOW OF
DRY AND SEASONABLY COLDER AIR WILL OVERSPREAD THE AREA SUNDAY
NIGHT AND MONDAY AS SPRAWLING HIGH PRESSURE BUILDS EAST FROM THE
WESTERN AND CENTRAL LAKES. THIS WILL RESULT IN OUR TEMPERATURES
DROPPING BACK TO MORE NORMAL LEVELS...ALONG WITH THE POTENTIAL FOR
SOME WEAK NORTHWEST FLOW LAKE EFFECT RAIN/SNOW SHOWERS SOUTHEAST OF
THE LAKES. THIS SAID...THE DRYNESS OF THE INCOMING AIRMASS...ONLY
MARGINALLY COLD TEMPS...AND POTENTIAL FOR SHEAR CONTINUE TO MAKE
THESE WORTHY OF NO MORE THAN ONLY SOME LOW CHANCE POPS SUNDAY
NIGHT...WITH THE ACTIVITY THEN LIKELY DYING OUT ALTOGETHER DURING
MONDAY DUE TO INCREASING SUBSIDENCE/SHEAR AND DIURNAL INFLUENCES.
OTHERWISE...CONDITIONS SHOULD BE PARTLY CLOUDY AND DRY BOTH SUNDAY
NIGHT AND MONDAY.
MONDAY NIGHT AND TUESDAY...THE AFOREMENTIONED SURFACE HIGH WILL
SETTLE DIRECTLY OVER NEW YORK STATE AND NEW ENGLAND. THIS WILL BRING
CONTINUED FAIR AND DRY WEATHER...ALONG WITH SEASONABLE TEMPS IN THE
MID 20S TO LOWER 30S MONDAY NIGHT...AND IN THE MID 40S TUESDAY.
LATE IN THE PERIOD...THE GFS AND ECMWF REMAIN IN DISAGREEMENT WITH
THE POSITION OF THE NEXT SOUTHERN STREAM STORM SYSTEM. THE GFS
REMAINS A BIT FURTHER NORTH AND BRINGS SOME LIGHT PRECIP INTO THE
SOUTHERN TIER AND FINGER LAKES TUESDAY NIGHT AND WEDNESDAY...WHILE
THE ECMWF RETAINS A MORE SUPPRESSED SOLUTION AND KEEPS US DRY. GIVEN
THE CONTINUED UNCERTAINTIES WITH THIS SYSTEM...WILL ELECT TO
FOLLOW THE ECMWF/HPC AND OUR CONTINUITY AND KEEP A DRY FORECAST IN
PLACE THROUGH THE END OF THE PERIOD...HOWEVER IT SHOULD BE KEPT IN
MIND THAT THIS REMAINS A RELATIVELY LOW CONFIDENCE FORECAST.
&&
.AVIATION /09Z THURSDAY THROUGH MONDAY/...
AN APPROACHING UPPER LEVEL TROUGH WILL BRING INCREASING MID TO HIGH
CLOUDS ACROSS WESTERN NY OVERNIGHT...HOWEVER CONDITIONS WILL REMAIN
VFR ACROSS ALL SITES THROUGH THE OVERNIGHT AND MORNING HOURS.
WESTERLY FLOW OFF THE LAKES COMBINED WITH COLD AIR ADVECTION WILL
INDUCE LAKE EFFECT SNOW SHOWERS EAST OF LAKE ONTARIO AND ACROSS THE
SOUTHERN TIER STARTING LATE THURSDAY AFTERNOON BRINGING MVFR
CONDITIONS TO KJHW. ANY LAKE EFFECT SNOW BANDS SHOULD STAY SOUTH OF
KART...WHICH SHOULD STAY VFR THROUGH THE FORECAST PERIOD.
OUTLOOK...
THURSDAY...VFR INLAND...IFR IN LAKE EFFECT SNOW EAST OF LAKES ERIE
AND ONTARIO.
FRIDAY THROUGH SATURDAY...MAINLY VFR.
SUNDAY...VFR EARLY THEN MVFR WITH CHANCE OF LAKE SNOW EAST OF THE
LAKES SUNDAY NIGHT.
MONDAY...MAINLY VFR.
&&
.MARINE...
MODERATE WESTERLY WINDS WILL CONTINUE TODAY THROUGH FRIDAY WITH
SOLID SMALL CRAFT ADVISORY CONDITIONS ON BOTH LAKES ERIE AND
ONTARIO. THE WINDS WILL BE ENHANCED BY COLD AIR OVER THE WARM LAKE
WATERS...WHICH PRODUCES AN UNSTABLE MARINE BOUNDARY LAYER WITH VERY
EFFICIENT DOWNWARD MOMENTUM TRANSFER.
WINDS SHIFT TO THE SOUTHWEST THIS WEEKEND WITH MILDER AIR
ARRIVING...BUT A MODERATE PRESSURE GRADIENT WILL KEEP SOLID SMALL
CRAFT ADVISORY CONDITIONS GOING BOTH SATURDAY AND SUNDAY. HIGH
PRESSURE BUILDS OVER THE LOWER LAKES BY MONDAY WITH WINDS AND WAVES
FINALLY SUBSIDING.
