AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 338 PM EDT WED AUG 8 2012 .SYNOPSIS... A WEAK COLD FRONT WILL MOVE ACROSS OUR AREA BY EARLY THIS EVENING...WITH SCATTERED SHOWERS AND THUNDERSTORMS ACCOMPANYING ITS PASSAGE. MAINLY DRY WEATHER WILL THEN FOLLOW THE FRONT TONIGHT... BEFORE LOW PRESSURE LIFTS NORTHEAST FROM THE OHIO VALLEY THURSDAY AND FRIDAY AND BRINGS INCREASINGLY UNSETTLED CONDITIONS. && .NEAR TERM /THROUGH THURSDAY/... AS OF 1930Z...THE SLOW-MOVING COLD FRONTAL BOUNDARY IS DRAPED ACROSS THE LOWER GREAT LAKES AND FAR WESTERN NEW YORK. WITH DAYTIME HEATING AND RESULTANT DIURNAL INSTABILITY...THIS FRONT AND LOCAL LAKE BREEZE BOUNDARIES/TERRAIN FEATURES HAVE COMBINED TO GENERATE SCATTERED CONVECTION ACROSS PORTIONS OF WESTERN NEW YORK. AS WE MOVE THROUGH THE REMAINDER OF THIS AFTERNOON AND THE EARLY EVENING HOURS...THE COLD FRONT WILL CONTINUE TO SLOWLY OOZE SOUTHEAST ACROSS THE FORECAST AREA...AND WILL EVENTUALLY EXIT TO OUR SOUTHEAST EARLY THIS EVENING BEFORE STALLING OUT A LITTLE TO OUR SOUTH OVERNIGHT. AS THIS FEATURE MOVES THROUGH...IT WILL CONTINUE TO GENERATE SCATTERED CONVECTION...FOR WHICH CHANCE POPS WILL REMAIN IN PLAY. FOLLOWING THE PASSAGE OF THE FRONT...THE LOSS OF BOTH LOW LEVEL CONVERGENCE AND DAYTIME HEATING SHOULD BRING AN END TO THE PRECIP DURING THE EARLY TO MID EVENING HOURS...WITH GENERALLY DRY WEATHER THEN EXPECTED TO FOLLOW FOR THE BALANCE OF THE NIGHT. WITH SCATTERED LOWER CLOUDS REMAINING IN PLACE AND MID AND HIGH CLOUDS INCREASING OVERNIGHT IN ADVANCE OF THE NEXT LOW...AT THIS POINT DO NOT EXPECT FOG TO BE A SIGNIFICANT FORECAST CONCERN OVERNIGHT. ON THURSDAY...CLOUDS WILL CONTINUE TO INCREASE AND THICKEN ACROSS THE AREA FROM SOUTHWEST TO NORTHEAST AS UPPER TROUGHING TAKES SHAPE ACROSS THE GREAT LAKES...AND AN ATTENDANT SURFACE LOW DEVELOPS AND LIFTS NORTHEAST ACROSS THE OHIO VALLEY. WITH DIURNAL HEATING...THE FRONTAL BOUNDARY STALLED OUT JUST TO OUR SOUTH MAY BECOME THE FOCUS FOR ANOTHER ROUND OF SCATTERED CONVECTION ACROSS THE SOUTHERN TIER AND FINGER LAKES DURING THE AFTERNOON...BEFORE THE MAIN SURFACE WAVE DRAWS CLOSE ENOUGH TO BRING INCREASING SHOWER/THUNDERSTORM CHANCES TO THE REST OF THE REGION LATER IN THE DAY. WILL CONTINUE TO INDICATE A NORTHEAST-SOUTHWEST GRADIENT IN PRECIP CHANCES ACROSS THE REGION TOMORROW AFTERNOON...RANGING FROM SLIGHT CHANCE/LOW CHANCE ACROSS THE SAINT LAWRENCE VALLEY AND NORTH COUNTRY...TO HIGH CHANCE ACROSS THE SOUTHERN TIER AND FAR WESTERN NEW YORK. WITH THE BEST INSTABILITY REMAINING ALONG AND SOUTH OF THE FRONT AND ANY STRONGER WIND FIELDS ALOFT REMAINING TO ITS NORTH...AT THIS POINT OUR SEVERE WEATHER POTENTIAL FOR TOMORROW AFTERNOON LOOKS TO BE RELATIVELY LOW. AS FOR TEMPERATURES...READINGS WILL AGAIN BE A LITTLE MILDER TONIGHT THAN LAST NIGHT...WITH LOWS RANGING FROM THE UPPER 50S/NEAR 60 ACROSS INTERIOR PORTIONS OF THE SOUTHERN TIER AND NORTH COUNTRY TO THE MID 60S ACROSS THE LAKE PLAINS. WITH 850 MB TEMPS OF +14C TO +16C AND INCREASING CLOUD COVER/PRECIP CHANCES THEN EXPECTED ON THURSDAY...DAYTIME HIGHS SHOULD RANGE FROM THE LOWER TO MID 80S IN MOST LOCATIONS. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... MUCH NEEDED BENEFICIAL RAINS CONTINUING TO LOOK PROMISING DURING THE THURSDAY NIGHT THROUGH FRIDAY NIGHT TIME FRAME...AS POTENT UPPER LEVEL LOW DROPS THROUGH THE GREAT LAKES. NAM/CANADIAN/GFS ALL ON BOARD IN CONTINUING TO DEVELOP INCREASING RAIN AREA...ALONG WITH SOME EMBEDDED STRONGER CONVECTION WITH THE INCREASING MID LEVEL FRONTOGENESIS AND SUBSTANTIAL HEIGHT FALLS TAKING PLACE. PRECIPITATION PATTERN LOOKS TO BECOME EVEN MORE FOCUSED LATE THURSDAY NIGHT AND FRIDAY. THE LOW/MID LEVEL BAROCLINIC ZONE EXTENDING ACROSS NEW YORK STATE WILL UNDERGO SIGNIFICANT FRONTOGENESIS AND DEEPEN IN RESPONSE TO INCREASING UPPER LEVEL DIVERGENCE AND INTENSE LARGE SCALE ASCENT JUST AHEAD OF THE PV ANOMALY...ALLOWING RAIN/EMBEDDED THUNDER TO INCREASE IN COVERAGE/INTENSITY. PLACEMENT OF HEAVIEST PRECIPITATION AXIS WILL BE A TOUGH CALL WITH STILL SOME MODEL DISCREPANCIES IN THE EXACT TRACK OF THE UPPER LEVEL LOW AND SUBSEQUENT SURFACE WAVE...AS WELL AS A MODEL AGREEMENT OF THE PRESENCE OF A SHARP DRY SLOT NOSING INTO A PORTION OF THE AREA. PRECIPITABLE WATER VALUES ACROSS THE ENTIRE AREA WILL BE RUNNING IN THE 1.5 TO 1.75 INCH RANGE. EXPECTATIONS ARE THAT A GENERAL WIDESPREAD 0.75 TO 1.25 INCHES OF RAIN WILL OCCUR...WITH HEAVIER AMOUNTS NEARING 2 INCHES VERY POSSIBLE ACROSS EASTERN SECTIONS OF THE AREA WHERE MODELS DO NOT PLACE ANY SIGNIFICANT DRY SLOTTING. THE STEADIEST PRECIPITATION SHOULD DROP OF FRIDAY NIGHT AND SATURDAY AS DEEP DRY SLOT WORKS INTO THE AREA BEHIND THE LOW AS IT PUSHES INTO ONTARIO. HOWEVER...WRAP AROUND MOISTURE BEGINS TO WORK INTO WESTERN SECTIONS DURING THE DAY SATURDAY...EVENTUALLY PUSHING THROUGH EASTERN SECTIONS BY SATURDAY NIGHT. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... HEIGHTS BEGIN TO RISE IN THE WAKE OF THE UPPER LOW FOR THE SECOND HALF OF THE WEEKEND. A LINGERING CYCLONIC FLOW OVER EASTERN SECTIONS OF THE AREA COULD TOUCH OFF A FEW SHOWERS...OTHERWISE THE OVERALL TREND IS TO DRY THINGS OUT FROM WEST TO EAST. HEIGHTS CONTINUING TO RISE THROUGH MID WEEK. FOR THE MOST PART EXPECT DRY WEATHER... ALTHOUGH GLOBAL MODELS SUGGESTING A COUPLE OF WEAK SHORT WAVES CROSSING THE REGION IN THE NORTHWEST FLOW ALOFT. HOWEVER...THESE MODELS DIFFER IN INTENSITY AND TRACK OF THE INDIVIDUAL WAVE WAND CONFIDENCE IS LOW THAT MUCH ACTIVITY WILL BE GENERATED...OTHER THAN SOME SPOTTY DIURNALLY DRIVEN CONVECTION. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... AS OF 1930Z...THE SLOW-MOVING COLD FRONTAL BOUNDARY IS DRAPED ACROSS THE LOWER GREAT LAKES AND FAR WESTERN NEW YORK. WITH DAYTIME HEATING AND RESULTANT DIURNAL INSTABILITY...THIS FRONT AND LOCAL LAKE BREEZE BOUNDARIES/TERRAIN FEATURES HAVE COMBINED TO GENERATE SCATTERED CONVECTION ACROSS PORTIONS OF WESTERN NEW YORK. AS WE MOVE THROUGH THE REMAINDER OF THIS AFTERNOON AND THE EARLY EVENING HOURS...THE COLD FRONT WILL CONTINUE TO SLOWLY OOZE SOUTHEAST ACROSS THE FORECAST AREA...AND WILL EVENTUALLY EXIT TO OUR SOUTHEAST EARLY THIS EVENING BEFORE STALLING OUT A LITTLE TO OUR SOUTH OVERNIGHT. AS THIS FEATURE MOVES THROUGH...IT WILL CONTINUE TO GENERATE SCATTERED CONVECTION...SOME OF WHICH COULD PRODUCE LOCALIZED REDUCTIONS TO IFR/MVFR. OTHERWISE...EXPECT VFR CONDITIONS TO PREVAIL OUTSIDE OF ANY CONVECTION. ONCE THE FRONT PASSES THROUGH THE AREA...MAINLY DRY VFR WEATHER IS EXPECTED TO RETURN FOR TONIGHT...WITH A GRADUAL INCREASE IN MID AND HIGH LEVEL CLOUDINESS EXPECTED OVERNIGHT. COUPLED WITH LINGERING SCATTERED LOWER VFR CLOUDS...THESE SHOULD HELP REDUCE THE RISK OF FOG OVERNIGHT. ON THURSDAY...CLOUD COVER WILL CONTINUE TO THICKEN ACROSS THE AREA THROUGH THE DAY IN ADVANCE OF LOW PRESSURE LIFTING NORTHEAST ACROSS THE OHIO VALLEY. EXPECT THE MORNING TO BE LARGELY DRY...WITH CONVECTIVE CHANCES THEN SLOWLY INCREASING DURING THE AFTERNOON AS THE LOW APPROACHES THE AREA AND DAYTIME INSTABILITY DEVELOPS. AS THE BULK OF ANY PRECIP WILL BE SCATTERED INITIALLY AND SHOULD HOLD OFF UNTIL CLOSE TO OR AFTER 18Z...FOR NOW HAVE ELECTED TO LEAVE THE TAFS DRY LATE IN THE PERIOD. OUTLOOK... THURSDAY NIGHT AND FRIDAY...IFR/MVFR IN RAIN WITH SCATTERED THUNDERSTORMS. SATURDAY...VFR/MVFR WITH A CHANCE OF SHOWERS AND THUNDERSTORMS. SUNDAY...MAINLY VFR. MONDAY...VFR. && .MARINE... A WEAK COLD FRONT WILL MOVE FINISH CROSSING THE LOWER LAKES BY EARLY THIS EVENING... WITH SCATTERED SHOWERS AND THUNDERSTORMS ACCOMPANYING ITS PASSAGE. MAINLY DRY WEATHER WILL THEN FOLLOW THE FRONT TONIGHT...BEFORE LOW PRESSURE LIFTS NORTHEAST FROM THE OHIO VALLEY THURSDAY AND FRIDAY AND BRINGS INCREASINGLY UNSETTLED CONDITIONS...INCLUDING THE THREAT OF SCATTERED THUNDERSTORMS. IN TERMS OF WINDS AND WAVES...GENERALLY LIGHT TO MODEST WINDS TO CONTINUE THROUGH THURSDAY...WITH WAVES REMAINING UNDER 2 FEET. AFTER THAT TIME...A STRENGTHENING NORTH TO NORTHEASTERLY FLOW WILL BRING A RISK OF ADVISORY LEVEL WINDS AND WAVES TO WESTERN LAKE ONTARIO BY FRIDAY MORNING. && .BUF WATCHES/WARNINGS/ADVISORIES...
