Area forecast discussion, Jul 7, 10:12 AM EST, 2 hours 58 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 1112 AM EDT SAT JUL 7 2012 .SYNOPSIS... A SLOW MOVING COLD FRONT WILL DROP ACROSS NEW YORK STATE TODAY... AND THIS WILL BRING US AT LEAST THE POTENTIAL FOR SOME BENEFICIAL SHOWERS AND THUNDERSTORMS WHILE ENDING OUR STRETCH OF VERY WARM WEATHER. HIGH PRESSURE OVER THE NORTHERN PLAINS WILL THEN DRIFT ACROSS THE GREAT LAKES...AND THIS WILL RESULT IN SEVERAL BEAUTIFUL DAYS ACROSS OUR REGION WITH AMPLE SUNSHINE AND COMFORTABLE TEMPERATURES. && .NEAR TERM /THROUGH TONIGHT/... A SLOW MOVING COLD FRONT STRETCHING ACROSS THE LENGTH OF LAKE ONTARIO WILL SETTLE ACROSS OUR FORECAST AREA DURING THE COURSE OF TODAY. WEAK CONVERGENCE ASSOCIATED WITH THIS FRONT WILL COMBINE WITH INCREASINGLY FAVORABLE THERMODYNAMICS TO PRODUCE SOME SCATTERED SHOWERS AND THUNDERSTORMS...BUT THE AREAL COVERAGE MAY BE LIMITED. THIS WILL BE PARTLY DUE TO THE LACK OF SIGNIFICANT HGT FALLS AND LACK OF SYNOPTIC LIFT...INCLUDING THE ABSENCE OF JET INDUCED LIFT. AS A RESULT...BASIN AVERAGE QPF SHOULD BE ABOUT A TENTH OF AN INCH OR LESS. THAT BEING SAID...THERE WILL BE ENOUGH DIURNALLY BASED HEATING THROUGH EARLY AFTERNOON ACROSS THE SRN TIER TO BOOST SBCAPES TO AT LEAST 2500 J/KG. THIS SHOULD PROMOTE MORE WIDESPREAD CONVECTION OVER THE WESTERN SOUTHERN TIER AND PORTIONS OF THE FINGER LAKES REGION THIS AFTERNOON. MID LEVEL LAPSE RATES IN THESE AREAS WILL LIKELY EXCEED 7 DEG C/KM...WITH 6 KM SHEAR FORECAST TO REACH 35 KTS OR SO. THIS COULD SUPPORT SOME STRONG TO POTENTIALLY SEVERE THUNDERSTORM ACTIVITY AS THE AFTERNOON PROGRESSES. THE MAIN SEVERE WEATHER THREATS WILL BE DAMAGING WIND GUSTS...AND BECAUSE OF THE DEEP POSITIVE CAPE VALUES...THERE WILL BE AN EQUAL RISK FOR LARGE HAIL. WILL ADD SOME ENHANCED WORDING FOR THIS AREA. IN TERMS OF TEMPERATURES...WE CAN EXPECT ONE MORE DAY OF VERY WARM AND HUMID CONDITIONS. MIDDAY AND EARLY AFTERNOON TEMPS SHOULD EASILY MAKE IT INTO THE MID 80S FOR MOST AREAS...WITH MERCURY READINGS CLIMBING INTO THE MID AND UPPER 80S ACROSS THE SRN TIER. AS THE FRONT PUSHES SOUTH ACROSS PENNSYLVANIA THIS EVENING...THE WEAKLY FORCED ENVIRONMENT WILL HAVE TO RELY ON LEFTOVER INSTABILITY TO GENERATE ANY SHOWERS/TSTMS. ANY RESIDUAL CONVECTION WILL WEAKEN AND DISSIPATE BY MIDNIGHT...AND THIS WILL BE FOLLOWED BY PARTIAL CLEARING FROM THE NORTH. TEMPERATURES TONIGHT WILL ONLY BE MARGINALLY LOWER THAN PREVIOUS NIGHTS...AS THE TRULY COOLER AND DRIER AIR WILL NOT SINK ACROSS THE LOWER GREAT LAKES UNTIL LATER IN THE WEEKEND. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... THIS PERIOD WILL FEATURE DRY AND MORE COMFORTABLE WEATHER AS SPRAWLING SURFACE HIGH PRESSURE OVER SOUTH CENTRAL CANADA RIDGES SOUTHEASTWARD INTO THE GREAT LAKES...AND BROAD UPPER-LEVEL TROUGHING SLOWLY DEEPENS ACROSS THE GREAT LAKES AND NEW ENGLAND. WITH PLENTIFUL SUNSHINE AND CONTINUED VERY DRY GROUND CONDITIONS...850 MB TEMPS OF +9C TO +14C WILL YIELD HIGHS IN THE UPPER 70S TO LOWER 80S BOTH SUNDAY AND MONDAY...WHILE MAINLY CLEAR SKIES AND LOWER HUMIDITY LEVELS WILL ALLOW FOR COMFORTABLE OVERNIGHT LOWS IN THE 50S BOTH SUNDAY AND MONDAY NIGHTS. && .LONG TERM /TUESDAY THROUGH FRIDAY/... IN THE LONG TERM...BROAD-SCALE TROUGHING WILL LINGER ACROSS THE GREAT LAKES AND NEW ENGLAND STATES THROUGH TUESDAY NIGHT...BEFORE SLOWLY WEAKENING AND RETRACTING NORTHEASTWARD THROUGH THE REMAINDER OF THE PERIOD. MEANWHILE AT THE LOW LEVELS...SURFACE-BASED RIDGING WILL CONTINUE TO SLOWLY BUILD SOUTHEAST ACROSS THE REGION... EVENTUALLY SUPPRESSING THIS WEEKEND'S FRONTAL BOUNDARY FURTHER TO THE SOUTH. THIS PATTERN WILL RESULT IN SEASONABLE TEMPERATURES CONTINUING RIGHT THROUGH TUESDAY...BEFORE SLOW MODERATION OF OUR AIRMASS RESULTS IN READINGS CREEPING BACK TO SLIGHTLY ABOVE AVERAGE LEVELS DURING THE SECOND HALF OF THE WORK WEEK. MORE SPECIFICALLY...DAYTIME HIGHS SHOULD CLIMB FROM THE UPPER 70S/LOWER 80S TUESDAY BACK TO THE MID 80S FOR THURSDAY AND FRIDAY...THOUGH ANY REAL UNCOMFORTABLE HEAT AND HUMIDITY SHOULD REMAIN DISPLACED WELL TO OUR SOUTH AND WEST. AS FOR RAINFALL CHANCES...THESE SHOULD REMAIN LARGELY NONEXISTENT THROUGH TUESDAY WITH PLENTIFUL DRY AIR REMAINING IN PLACE...AND THEN RELATIVELY MINIMAL THEREAFTER. THE 12Z GFS REMAINS A BIT SLOWER WITH THE DEPARTURE OF THE MAIN UPPER TROUGH AXIS DURING THE MIDWEEK PERIOD...AND CONSEQUENTLY PULLS THE FRONTAL BOUNDARY TO OUR SOUTH BACK FAR ENOUGH TO THE NORTH TO ALLOW FOR A LOW-END SHOWER THREAT IN THE WEDNESDAY-THURSDAY TIME FRAME. HOWEVER...DO NOT HAVE A LOT OF FAITH IN THIS SCENARIO GIVEN THE LACK OF RECENT RUN TO RUN CONSISTENCY SEEN IN THE GFS AT THIS TIME FRAME. INSTEAD...TEND TO FAVOR THE FASTER AND MORE CONSISTENT ECMWF AND GEM...WHICH KEEP THE MAIN FRONTAL BOUNDARY SUPPRESSED FURTHER SOUTH WITH GENERALLY DRY WEATHER CONTINUING THROUGH THURSDAY...FOLLOWED BY A VERY LOW POTENTIAL FOR SOME SHOWERS ON FRIDAY ASSOCIATED WITH THE PASSAGE OF A WEAK SECONDARY TROUGH. WITH THE ABOVE IN MIND...WILL KEEP POPS IN THE EXTENDED PERIODS CONFINED TO THE SLIGHT CHANCE RANGE AND BELOW FOR NOW...WITH PREDOMINANTLY DRY WEATHER CONTINUING. && .AVIATION /15Z SATURDAY THROUGH WEDNESDAY/... A COLD FRONT CROSSING THE REGION FROM NORTH TO SOUTH WILL TRIGGER SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON ACROSS WESTERN AND NORTH CENTRAL NEW YORK. THERE IS A POTENTIAL THAT SOME OF THESE THUNDERSTORMS MAY BECOME SEVERE IN THE SOUTHERN TIER THIS AFTERNOON WITH THE MAIN THREAT BEING STRONG GUSTY WINDS...HOWEVER CONFIDENCE IN LOCATION/TIMING OF ANY DEVELOPING CONVECTION IS LOW AT THIS POINT. CONDITIONS WILL GENERALLY BE VFR WITH AREAS OF MVFR AND BRIEF IFR CONDITIONS IN ANY SHOWERS AND THUNDERSTORMS. THE FRONT WILL PUSH THROUGH THE REGION THIS EVENING BRINGING AN END TO ANY SHOWERS AND THUNDERSTORMS. WHILE VFR CONDITIONS SHOULD PREVAIL OVERNIGHT...THERE IS A CHANCE THAT THE SOUTHERN TIER WILL SEE ANOTHER ROUND OF FOG AGAIN TONIGHT BRINGING IFR CONDITIONS TO KJHW AFTER MIDNIGHT THROUGH EARLY SUN MORNING. OUTLOOK... SUNDAY THROUGH WEDNESDAY...VFR. && .MARINE... A COOL FRONT WILL SLOWLY DRIFT SOUTH ACROSS THE LOWER GREAT LAKES TODAY...AND WHILE WINDS AND WAVES WILL REMAIN WELL BELOW SMALL CRAFT ADVISORY CRITERIA...THERE WILL BE THE POTENTIAL FOR SOME THUNDERSTORMS. FAVORABLE CONDITIONS FOR RECREATIONAL BOATING WILL RETURN LATER TONIGHT AND SUNDAY AS HIGH PRESSURE WILL BUILD EAST FROM THE NORTHERN PLAINS. THIS WILL KEEP GENTLE TO MODERATE BREEZES ON LAKES ERIE AND ONTARIO WITH NEGLIGIBLE WAVES. TRANQUIL CONDITIONS WILL CONTINUE WELL INTO THE MIDDLE OF NEXT WEEK AS HIGH PRESSURE WILL BE FOUND OVER THE REGION. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...NONE.
