NWS Buffalo, NY wrote its last area forecast discussion before the first event at Jun 23, 2:51 AM EST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 351 AM EDT THU JUN 23 2011 .SYNOPSIS... UNSETTLED WEATHER WILL CONTINUE THROUGH THE END OF THE WEEK WITH A SLOW MOVING COLD FRONT AND AREA OF LOW PRESSURE BRINGING SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY NIGHT. CONDITIONS WILL IMPROVE SOME ON SATURDAY WITH JUST A FEW PASSING SHOWERS ALTHOUGH IT WILL BE UNSEASONABLY COOL. DRY WEATHER WILL RETURN ON SUNDAY WITH MIDSUMMER WARMTH ARRIVING AGAIN NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... THROUGH DAYBREAK...A BROKEN LINE OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO WEAKEN AS IT MOVES EASTWARD DURING THE EARLY MORNING HOURS. AFTER DROPPING UP TO AN INCH OF RAIN IN PORTIONS OF THE SOUTHERN TIER...THE WEAKENING TREND SHOULD LIMIT RAINFALL AMOUNTS EASTWARD...WITH THE HRRR HAVING A GOOD TRACK RECORD WITH THIS...WILL STICK FAIRLY CLOSE TO IT. FOR TODAY...WHILE A ROUND OF SHOWERS AND THUNDERSTORMS IS STILL EXPECTED TODAY...DO TREND FORECAST MORE OPTIMISTIC. FIRST...EXPECT THE EXIT OF THIS EARLY MORNING ACTIVITY TO GIVE WAY TO A PERIOD OF DRY WEATHER IN MOST AREAS...EVEN WITH SOME MORNING SUN. BOTH THE 00Z NAM/RGEM FORECAST SOME BREAKS OF SUNSHINE WEST OF ROCHESTER THIS MORNING...AND SATELLITE TRENDS SEEM TO SUPPORT THIS IDEA. WILL HANG ONTO A CHANCE IN EASTERN SECTIONS WHERE WHATEVER IS LEFT OF THE LINE WOULD BE...BUT SEE ONLY A SLIGHT CHANCE OF SHOWERS IN WESTERN PORTIONS THIS MORNING. WARMING DAYTIME TEMPERATURES...AND POSSIBLY A DECENT PERIOD OF SUN...WILL HELP DESTABILIZE THINGS BY THIS AFTERNOON. IN ADDITION...A 500 MB TROF REMAINS TO THE WEST...WITH A SHORTWAVE AND PRE-FRONTAL TROF FORECAST TO CROSS THE REGION THIS AFTERNOON. NOT TERRIBLY HIGH CONFIDENCE IN THIS...BUT FEEL THE MOST LIKELY EVOLUTION IS FOR SHOWERS AND THUNDERSTORMS TO BREAK OUT FROM ROUGHLY JWH-ROC MID TO LATE AFTERNOON...WITH THIS STRENGTHENING AS IT MOVES EAST-NORTHEAST LATE AFTERNOON INTO THE EVENING. THIS IS GENERALLY SUPPORTED BY A QPF BLEND AMONG THE NAM/GFS/SREF...AND IS CLIMATOLOGICALLY FEASIBLE IN THAT STORMS OFTEN DEVELOP IN THIS MANOR. BASED ON THIS...DO TREND POPS ON THE NIAGARA FRONTIER DOWN TO CHANCE...WHERE THE SW FLOW OFF THE LAKE SHOULD SOMEWHAT LIMIT THE CHANCES FOR STORMS BUFFALO NORTH AND WEST. ONE LAST THING TO WATCH IS THE LAKE ONTARIO BREEZE...WHICH MAY SPAWN SOME STORMS OUT AHEAD OF THIS LINE LATE AFTERNOON. AS FOR SEVERE WEATHER POTENTIAL...THERE WILL BASICALLY BE MODERATE INSTABILITY IN PLACE...WITH WEAK TO MODERATE SHEAR. 850 MB WINDS ONLY TOP OUT AT 25 TO 30 KTS...BUT WITH THE POSITION OF THE TROF AND SHORTWAVE...THE CHANCE FOR CONVECTIVE INITIATION IS QUITE HIGH. INITIALLY EXPECT PULSE CONVECTION...WITH THIS POSSIBLY EVOLVING INTO LINES OR LINE SEGMENTS. THIS PRESENTS A SLIGHT RISK FOR STRONG WIND GUSTS AND LARGE HAIL. LOCALLY HEAVY RAINFALL IS ALSO A POSSIBILITY WITH PRECIPITABLE WATER VALUES NEAR 1.50 INCHES ON THE 00Z BUF SOUNDING. THE BEST CHANCE FOR HEAVY RAIN AND/OR SEVERE WEATHER WOULD BE SE OF I-90 IN THE SOUTHERN TIER...GENESEE VALLEY...AND FINGER LAKES REGIONS. OTHERWISE...EXPECT A FAIRLY MUGGY DAY...WITH HIGHS GENERALLY IN THE LOWER 80S...THOUGH HUMIDITY WILL MAKE IT FEEL WARMER. FOR TONIGHT...THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS SHOULD BE EAST OF LAKE ONTARIO...WITH SREF/NAM/GFS GENERALLY SHOWING A WEAKENING SHORTWAVE EXITING EAST. THIS SHOULD PUSH WHAT CONVECTION DOES DEVELOP DURING THE DAY WITH IT...WITH MARGINAL SEVERE WEATHER AND FLOODING CONCERNS LINGERING INTO THE EVENING HOURS EAST OF LAKE ONTARIO. OTHERWISE...CAN/T RULE OUT A STRAY SHOWER OR THUNDERSTORM BEHIND THIS...BUT COVERAGE SHOULD BE FAIRLY SPARSE. WHILE IT SHOULD BE SLIGHTLY DRIER IN THE BOUNDARY LAYER BEHIND THIS FIRST ROUND OF CONVECTION...ANOTHER SHORTWAVE DOES APPROACH LATE TONIGHT. WILL BRING BACK CHANCE POPS INTO WESTERN SECTIONS LATE TONIGHT WITH THIS...AS THE FIRST ROUND EXITS EAST LATE TONIGHT. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... THE UPPER LEVEL LOW THAT IS PRESENTLY OVER THE WESTERN GREAT LAKES THIS THURSDAY MORNING WILL ROTATE ACROSS THE EASTERN GREAT LAKES ON FRIDAY. MULTIPLE SHORT WAVES ADVANCING AROUND THIS UPPER LEVEL LOW...COMBINED WITH DEEP LOW LEVEL MOISTURE WILL ALLOW FOR LIKELY AND CATEGORICAL POPS ACROSS THE REGION. OF LESS CERTAINTY WILL BE AMOUNT AND COVERAGE OF THUNDER. THE UPPER LEVEL COOL POOL AND MID LEVEL LAPSE RATES ARE NOT OVERLY IMPRESSIVE FOR THUNDER. INSTABILITY TO THE WEST REMAINS MINIMAL...THOUGH FURTHER TO THE EAST AND AHEAD OF THE UPPER LEVEL LOW SFC BASED CAPES OF 250 TO 750 J/KG...LI'S DROPPING TO -2 AND STEEPER LAPSE RATES SUPPORT THE DEVELOPMENT OF THUNDERSTORMS. HOWEVER WITH A WEAK SFC BOUNDARY CROSSING THE REGION WILL INCLUDE THUNDER POTENTIAL ACROSS THE CWA AND EXPECT MOST OF THESE THUNDERSTORMS TO BLOSSOM IN THE HEATING OF THE AFTERNOON...AND WILL FOCUS THE THUNDER POTENTIAL FOR THE AFTERNOON AND INTO THE EVENING HOURS. TEMPERATURES FRIDAY WILL BE COOLER AS THE UPPER LEVEL LOW PASSES WITH THE WARMEST HIGHS EXPECTED ACROSS THE EAST. DEW POINTS WILL ONLY FALL A FEW DEGREES DURING THE DAY FRIDAY...SO IT WILL NOT FEEL AS HUMID AS THURSDAY...BUT THE REAL FALL IN SFC DEW POINTS WILL COME FRIDAY NIGHT. COMFORTABLE FRIDAY NIGHT WITH TEMPERATURES FALLING BACK TOWARDS NORMAL. A FEW SHOWERS AND EARLY EVENING THUNDERSTORMS WILL REMAIN AS ANOTHER SHORT WAVE DIVING DOWN THE WEST SIDE OF THE UPPER LEVEL LOW WILL REINFORCE THE UPPER LEVEL LOW OVER US. SATURDAY SHOWERS WILL CONTINUE TO FORM AS THE CORE OF THE COLDEST AIR PASSES ACROSS THE REGION. BY AFTERNOON THIS CORE WILL BE FOCUSED ON THE FINGER LAKES REGION AND WITH DAYTIME HEATING A RUMBLE OF THUNDER IS POSSIBLE ACROSS THE EASTERN LAKE ONTARIO REGION...BUT EXPECT JUST SCATTERED SHOWERS ELSEWHERE. COOLER ON SATURDAY WITH 60S THROUGH THE DAY UNDER CONSIDERABLE CLOUDINESS. AS THE UPPER LEVEL LOW DEPARTS SATURDAY NIGHT SHOWERS WILL END. WILL CONTINUE WITH CHC POPS SATURDAY NIGHT...MAINLY ACROSS THE GENESEE VALLEY AND POINTS EASTWARD. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... TEMPERATURES THIS TIME PERIOD WILL START COOL...BUT WITH THE RETURN OF SUNSHINE TEMPERATURES WILL RISE TO NORMAL AND ABOVE ON MONDAY...AND LIKELY REMAIN THIS WAY AHEAD OF OUR NEXT WEATHER SYSTEM OF NOTE. HIGH PRESSURE WILL BUILD INTO THE REGION ON SUNDAY AND MONDAY WITH FAIR WEATHER. 500 HPA HEIGHTS WILL CONTINUE TO RISE THROUGH MONDAY...THOUGH AN EARLY SHOWER SUNDAY CANNOT BE RULED OUT TOWARDS THE EAST. AS THIS SFC HIGH BUILDS ACROSS THE EASTERN LAKES LATER SUNDAY AND INTO MONDAY EXPECT CLEAR SKIES. WAA CLOUDINESS WILL BEGIN TO PUSH BACK INTO THE REGION LATER MONDAY...IN ADVANCE OF OUR NEXT SYSTEM. INCREASING HUMIDITY ON TUESDAY AND INTO WEDNESDAY AS SFC HIGH PRESSURE SLIDES OFF TO THE EAST COAST AND A RETURN FLOW OF MOISTURE FROM THE GULF PUSHES NORTHWARD. ANOTHER SYSTEM APPROACHES NEXT TUESDAY AND WEDNESDAY AND WILL CARRY LOW CHC POPS FOR SHOWERS AND THUNDERSTORMS WITH THIS. && .AVIATION /08Z THURSDAY THROUGH MONDAY/... THROUGH 12Z...A LINE OF THUNDERSTORMS WILL CONTINUE TO WEAKEN...BUT STILL WILL IMPACT JHW...AND POSSIBLY BUF THROUGH 08Z OR SO. OTHERWISE...MAINLY VFR CONDITIONS OUTSIDE OF THIS LINE...THOUGH ANY BRIEF CLEARINGS WILL ALLOW FOG TO DEVELOP...AS IT DID IN ART. WILL MONITOR FOR THIS...WITH JHW POSSIBLY SEEING A PERIOD OF IFR OR LOWER CONDITIONS IN FOG THIS MORNING IF CLOUDS CLEAR OUT. FOR NOW HEDGE TAF OPTIMISTIC. FOR TODAY...EXPECT MAINLY VFR CONDITIONS IN THE MORNING. SHOWERS AND THUNDERSTORMS WILL DEVELOP THIS AFTERNOON...BUT EXPECT COVERAGE TO BE SCATTERED IN NATURE NE OF THE LAKES NEAR BUF/IAG/ART...WITH A BETTER CHANCE FOR STORMS AT ROC/JHW DURING THE AFTERNOON. WHAT DOES DEVELOP SHOULD SLIDE EAST THIS EVENING...POSSIBLY IMPACTING ART. OUTLOOK... THURSDAY NIGHT AND FRIDAY...VFR/MVFR WITH A FEW ROUNDS OF SHOWERS AND THUNDERSTORMS. SATURDAY...VFR/MVFR WITH A CHANCE OF SHOWERS. SUNDAY AND MONDAY...VFR. && .MARINE... EXPECT WINDS TO BE ON THE LIGHT SIDE TODAY AND TONIGHT...WITH NO HEADLINES FOR WINDS LIKELY. HOWEVER...THERE MAY BE SOME THUNDERSTORMS WHICH MOVE ACROSS THE WATERS...RESULTING IN GUSTY WINDS...WITH MAIN CONCERN FOR THIS ON THE EASTERN HALF OF LAKE ONTARIO. LOW PRESSURE LIFTING INTO NORTHERN ONTARIO ON FRIDAY AND FRIDAY NIGHT WILL SET UP A DECENT SW FLOW...MARGINAL TO SCA CRITERIA AT 15 KTS OR SO ON LAKE ERIE. BEYOND THIS...HIGH PRESSURE BUILDS IN WITH NO HEADLINES ANTICIPATED FOR THE WEEKEND. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...NONE.
