AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
530 PM EDT TUE SEP 7 2010

.SYNOPSIS...
LOW PRESSURE OVER THE CENTRAL GREAT LAKES WILL TRACK INTO
SOUTHERN ONTARIO TONIGHT AND SWING A STRONG COLD FRONT THROUGH THE
AREA. THIS WILL BRING A ROUND OF SHOWERS AND A FEW THUNDERSTORMS
ALONG THE COLD FRONT THIS EVENING...THEN WILL USHER IN A FRESH
BATCH OF COOLER AIR FOR THE SECOND HALF OF THE WEEK.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AN ANOMALOUSLY DEEP AND COOL LOW OVER THE CENTRAL GREAT LAKES AT MID
AFTERNOON WILL MOVE EAST ACROSS SOUTHERN TONIGHT AND TO QUEBEC
PROVINCE ON WEDNESDAY. BOUNDARY PERHAPS BEST DEFINED BY THE DEW
POINT GRADIENT...WITH THE WIND SHIFT SUBTLE AND TRAILING THE
CONVECTION. OVER THE PAST COUPLE HOURS...SHOWERS AND THUNDERSTORMS
HAVE EXPANDED ACROSS CENTRAL OHIO. CONSENSUS SUGGESTS WIND FIELD
IS FAVORABLE FOR STRONG THUNDERSTORMS...WITH 850 MB WINDS
INCREASING TO AROUND 50 KTS...WITH SOME DIRECTIONAL SHEAR.
INSTABILITY REMAINS THE LIMITING FACTOR. A NARROW BAND OF DEW
POINTS IN THE 60S IS QUICKLY ADVECTING AHEAD OF THE
BOUNDARY...WITH WATER VAPOR SHOWING AT LEAST A SOME FUNNELING OF
TROPICAL MOISTURE. THIS MOISTURE IS OF COURSE THE KEY TO
INSTABILITY...WITH ACTIVITY UPSTREAM IN OHIO SUGGESTING SUFFICIENT
INSTABILITY FOR SOME STRONG TO SEVERE STORMS. THE QUESTION FOR US
WILL BE HOW MUCH MOISTURE MAKES IT IN AHEAD OF THE BOUNDARY. THUS
FAR HRRR HAS PROVEN TO HAVE A GOOD HANDLE ON THIS...WITH LATEST
RUNS SUGGESTING THE SOUTHERN TIER MAY SEE SOME DECENT
THUNDERSTORMS EARLY EVENING. FORECAST SOUNDINGS SUGGEST LESS
POTENTIAL FOR SURFACE BASED CONVECTION AFTER 03Z OR SO. BASED ON
THIS...WILL UPDATE ZONES AND ADD A MENTION OF GUSTY WINDS SOUTH OF
BUFFALO AND ON LAKE ERIE. WILL LEAVE OUT NORTH OF I-90 FOR
NOW...THINKING MOISTURE WILL BE TOO LITTLE TO LATE. AGAIN...FOCUS
WILL BE BETWEEN 7 PM AND 10 PM...MAINLY IN THE SOUTHERN TIER.
OTHERWISE...SHARPEN AND TWEAK POPS BASED ON RADAR AND LATEST MODEL DATA.

MUCH COOLER AIR FOLLOWING THE FRONT WILL SET LAKE EFFECT CLOUDS AND
SHOWERS TO THE EAST OF LAKES ERIE AND ONTARIO. NAM/GFS/SREF ALL SHOW
SOME LAKE EFFECT WITH THE HIGHER POPS TO THE EAST OF  LAKE ONTARIO
WITH THE LONGER FETCH AND COOLER 850MB TEMPS. WILL HAVE CHANCE POPS
EAST OF LAKE ERIE AND LIKELY POPS FOR THE EASTERN LAKE ONTARIO
COUNTIES. WITH THE COOLER AIR ALOFT AND GREATER INSTABILITY...EXPECT
CLOUDIER SKIES INLAND DURING WED AFTERNOON.

TEMPS TONIGHT WILL FALL TO THE MIDDLE 50S FOLLOWING THE FRONTAL
PASSAGE...THEN RECOVER ONLY TO THE LOWER TO MID 60S ON WEDNESDAY
WITH THE CLOUD COVER AND CONTINUED COLD ADVECTION.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
WEDNESDAY NIGHT AND THURSDAY A LONGWAVE TROUGH WILL SHARPEN OVER
SOUTHEAST CANADA AND NEW ENGLAND AS A MID LEVEL CUTOFF LOW MOVES
FROM SOUTHERN QUEBEC INTO MAINE. THIS WILL KEEP A COOL/MOIST
CYCLONIC FLOW ACROSS THE LOWER LAKES THROUGH MUCH OF THE SHORT TERM
PERIOD. THE BEST CHANCES FOR MORE WIDESPREAD SYNOPTIC SCALE PRECIP
WILL BE ACROSS THE NORTH COUNTRY IN CLOSER PROXIMITY TO THE MID
LEVEL CUTOFF AND SURFACE LOWS. SEVERAL VORTICITY MAXIMA WILL ROTATE
ACROSS NEW ENGLAND AROUND THE MID LEVEL CUTOFF...THE MOST NOTABLE OF
WHICH WILL CROSS THE SAINT LAWRENCE VALLEY LATE WEDNESDAY NIGHT AND
THURSDAY MORNING. THE COVERAGE OF SYNOPTIC SCALE SHOWERS WILL
DIMINISH WITH WESTERN EXTENT...ALTHOUGH A FEW BRIEF SHOWERS CANNOT
BE RULED OUT EVEN ACROSS WESTERN NY THROUGH THURSDAY.

WITH 850MB TEMPS DOWN AROUND +6C...LAKE EFFECT RAIN POTENTIAL IS
ALSO A CONSIDERATION. LAKE TEMPERATURES ARE SEVERAL DEGREES COOLER
THAN THE EVENT THIS PAST WEEKEND...AND 850MB TEMPS ARE SEVERAL
DEGREES WARMER. THIS COMBINATION WILL RESULT IN LESS INSTABILITY
THAN THE WEEKEND EVENT...WITH CONDITIONAL INSTABILITY AS OPPOSED TO
MODERATE. LAKE INDUCED CAPE WILL BE AROUND 400J/KG WITH EQUILIBRIUM
LEVELS AROUND 13K FEET. ALSO...INITIAL WESTERLY FLOW EARLY WEDNESDAY
EVENING WILL GRADUALLY BECOME MORE NORTHWEST LATER WEDNESDAY NIGHT
AND THURSDAY. THE SHORTENING FETCH WILL ALSO CREATE A LESS FAVORABLE
ENVIRONMENT FOR ORGANIZED LAKE EFFECT RAIN...ALTHOUGH SHOWERS WILL
STILL BE POSSIBLE THROUGH THE PERIOD.

OFF LAKE ONTARIO...LATEST MESOSCALE MODEL GUIDANCE AND OVERALL
SYNOPTIC SETTING SUGGESTS A DECENT BAND OF LAKE EFFECT RAIN MAY BE
ONGOING EARLY WEDNESDAY EVENING ACROSS OSWEGO COUNTY. AS BOUNDARY
LAYER FLOW VEERS MORE NORTHWEST OVERNIGHT...EXPECT THIS TO PUSH TO
THE SOUTHEAST CORNER OF THE LAKE AND TEND TO BREAK APART INTO
SCATTERED SHOWERS OVERNIGHT AS THE FETCH DIMINISHES AND FLOW BECOMES
MORE NORMAL TO THE LONG AXIS OF THE LAKE. WHILE LAKE EFFECT WILL
DIMINISH...EXPECT A GENERAL INCREASE IN WRAP AROUND AND UPSLOPE
SHOWERS OVERNIGHT AS THE MID LEVEL LOW DIGS INTO NEW ENGLAND. EXPECT
MORE OF THE SAME THURSDAY WITH A COMBINATION OF LAKE ENHANCED AND
WRAP AROUND SHOWERS EAST AND SOUTHEAST OF LAKE ONTARIO.

OFF LAKE ERIE...CONDITIONS WILL BE LESS FAVORABLE WITH A SHORT WNW
OR NW FETCH. SYNOPTIC SCALE MOISTURE WILL ALSO BE MORE SHALLOW AND
KEEP THE FAVORABLE CLOUD MICROPHYSICS ZONE WELL ABOVE THE LAKE
INDUCED MIXED LAYER. GIVEN THE LESS FAVORABLE CONDITIONS...WILL ONLY
GO WITH CHANCE POPS SOUTHEAST OF LAKE ERIE. IF ANY SHOWERS DO FORM
THEY WILL BE LIGHT AND FOCUS ACROSS THE HIGHER TERRAIN OF THE
CHAUTAUQUA RIDGE WHERE UPSLOPE FLOW WILL GIVE AN ADDED BOOST.

BY FRIDAY THE MID LEVEL LOW AND ASSOCIATED SURFACE LOW WILL PULL OUT
INTO ATLANTIC CANADA AND LOOSEN THEIR GRIP ON THE LOWER LAKES. A
RIDGE OF HIGH PRESSURE SURFACE AND ALOFT WILL BEGIN TO BUILD INTO
THE AREA WITH A RETURN TO SUNSHINE ACROSS WESTERN NY. STILL MAY SEE
A FEW LINGERING SHOWERS EAST OF LAKE ONTARIO...BUT THIS TOO SHOULD
END BY FRIDAY EVENING AS THE LOW MOVES AWAY.

IT WILL BE QUITE COOL THURSDAY AND FRIDAY WITH 850MB TEMPS AROUND
+6C. THIS WILL SUPPORT HIGHS IN THE MID 60S ACROSS LOWER ELEVATIONS
THURSDAY WITH SOME UPPER 50S ACROSS HIGHER TERRAIN...ESPECIALLY EAST
OF LAKE ONTARIO WHERE CLOUDS AND SHOWERS WILL BE MORE NUMEROUS. ON
FRIDAY ONLY EXPECT TO TACK ON A FEW DEGREES WITH UPPER 60S ACROSS
LOWER ELEVATIONS AND LOW TO MID 60S HIGHER TERRAIN.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AT THE START OF THE PERIOD A NARROW RIDGE OF HIGH PRESSURE SURFACE
AND ALOFT WILL BUILD OVER THE LOWER LAKES AND BRING A SUNNY DAY ON
SATURDAY WITH SEASONABLE TEMPERATURES. MEDIUM RANGE MODEL GUIDANCE
IS IN BETTER AGREEMENT TODAY WITH THE TIMING AND AMPLITUDE OF THE
NEXT SYSTEM TO APPROACH THE AREA LATER SATURDAY NIGHT OR SUNDAY. THE
NEW 12Z GFS AND ECMWF ARE BOTH TIGHTLY CLUSTERED AROUND A COMMON
SOLUTION AND HAVE GOOD SUPPORT FROM THE GEFS MEAN. BOTH MODELS TAKE
ANOTHER PACIFIC SYSTEM ACROSS SOUTHERN CANADA WITH A WEAKENING MID
LEVEL TROUGH CROSSING THE LOWER LAKES ON SUNDAY. THE ASSOCIATED
SURFACE FRONT WILL BE OCCLUDED WITH LITTLE PUSH OF COOLER AIR BEHIND
IT. PREVIOUS CONTINUITY LOOKS GOOD FOR THIS PERIOD AND WILL CONTINUE
WITH CHANCE POPS FOR SATURDAY NIGHT AND SUNDAY. DRY WEATHER SHOULD
RETURN FOR MONDAY BEHIND THE WEAK FRONTAL PASSAGE.

BY TUESDAY OF NEXT WEEK MODELS BEGIN TO DIVERGE SOMEWHAT...AS TO BE
EXPECTED ON DAY 7. THE GFS IS MOST AGGRESSIVE IN DROPPING A BACKDOOR
FRONT ACROSS THE AREA BY EARLY TUESDAY. THE ECMWF IS A LITTLE SLOWER
AND KEEPS THE LOWER LAKES ON THE WARM SIDE OF THE BOUNDARY FOR
TUESDAY. 12Z GEFS ENSEMBLE MEMBERS SHOW A SPLIT WITH SOME MEMBERS
SUPPORTING THE FASTER OPERATIONAL GFS AND SOME IN THE SLOWER ECMWF
CAMP. FOR NOW WILL JUST USE LOW CHANCE POPS ON TUESDAY AND LEAN
TOWARDS THE WARMER ECMWF FOR TEMPS.

&&

.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
COLD FRONT WILL MOVE THROUGH BETWEEN 00Z AND 06Z WITH A NARROW SWATH
OF SHOWERS AND ISOLATED THUNDER. LACK OF MOISTURE WILL LIMIT THE
STRENGTH OF THE PRECIP SO EXPECT VFR CONDITIONS TO PREVAIL EVEN
DURING FRONTAL PASSAGE...ALTHOUGH A BRIEF DOWNPOUR MAY ACCOMPANY ANY
THUNDERSTORMS. DRY SLOT WILL WORK INTO THE AREA BEHIND THE FRONTAL
PASSAGE.

LAKE EFFECT CLOUDS AND PRECIP SET UP ON WEDNESDAY WHICH WILL MAINLY
AFFECT KJHW AND KART. STILL DONT EXPECT CIGS TO BE LOWER THAN LOW
VFR RANGE NOR EXPECT HEAVIER/STEADIER PRECIP TO DIRECTLY IMPACT KJHW
OR KART.

OUTLOOK...
WEDNESDAY AND THURSDAY...VFR/MVFR WITH A CHANCE OF SHOWERS...
EXCEPT EAST OF LAKE ONTARIO WHERE SHOWERS WILL BE LIKELY.
FRIDAY AND SATURDAY...MAINLY VFR.
SUNDAY...MVFR IN SCATTERED SHOWERS.

&&

.MARINE...
SOUTH AND SOUTHWEST WIND AHEAD OF THE COLD FRONT WILL TURN SHARPLY
TO THE WEST AND NORTHWEST FOLLOWING FRONTAL PASSAGE THIS EVENING.
SMALL CRAFT CRITERIA WIND AND WAVES WILL SPREAD OUT ACROSS BOTH
LAKES. VERY LITTLE BREAK IN THE HIGHER WINDS AND WAVES IS EXPECTED
THROUGH AT LEAST THURSDAY AS A STRONG COLD FRONT  CROSSES THE AREA
TONIGHT...WITH A FAIRLY STRONG PRESSURE GRADIENT AND COLD ADVECTION
FOLLOWING IN ITS WAKE FOR BOTH WEDNESDAY AND THURSDAY. WILL EXTEND
THE SMALL CRAFT ADVISORY THROUGH THURSDAY EVENING...AND IT COULD GO
EVEN FURTHER SHOULD THESE CONDITIONS CONTINUE.

&&
