NWS Albany, NY wrote its last area forecast discussion before the first event at Jun 24, 10:10 AM EST, 2 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 1110 AM EDT THU JUN 24 2010 .SYNOPSIS... SHOWERS AND THUNDERSTORMS WILL ACCOMPANY A LOW PRESSURE SYSTEM AS IT MOVES ACROSS THE REGION TODAY. A COOLER AND DRIER AIR MASS WILL FILTER IN TONIGHT WITH DRY AND SEASONABLE WEATHER FOR FRIDAY. ANOTHER LOW PRESSURE SYSTEM WILL APPROACH THIS WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... AS OF 1100 AM...NOT MUCH CU YET IN THE WATCH AREA...EXCEPT IN THE ADIRONDACKS WHERE SHOWERS WITHOUT LIGHTING HAVE DEVELOPED. FREEZING LEVEL OFF OUR SOUNDING HIGH AT OVER 14,000 FEET...-20C OVER 25,000 FEET. HAIL NOT AS MUCH ASA THREAT...BUT IMPRESSIVE UNIDIRECTIONAL WIND SHEAR COULD PRODUCE GOOD BOWING SEGMENT. EXPECT CONVECTION TO FIRE UP IN THE NEXT COUPLE OF HOURS. FOR NOW...NEED TO RAISE TEMPS 3-6 DEGREES ACROSS THE BOARD. NO OTHER CHANGES. SEVERE THUNDERSTORM WATCH #404 IS IN EFFECT UNTIL 22Z/THURSDAY FOR ALL BUT HERKIMER AND HAMILTON COUNTIES. MAIN THREAT DAMAGING WINDS. PREVIOUS DISCUSSION ISSUED AT 959 AM...UPDATED GRIDS TO BETTER TIME CONVECTION ACROSS FORECAST AREA. THE STORM PREDICTION CENTER AS ISSUED A MESOSCALE DISCUSSION #1109 WHICH INCLUDES A PORTION OF THE FORECAST AREA. BEST CHANGES FOR SEVERE THUNDERSTORMS WILL BE SOUTH OF THE CAPITAL DISTRICT WHERE INSTABILITY WILL BE GREATEST. CONVECTION HAS FIRED UP HEAD OF THE COLD FRONT ACROSS WESTERN PA AND IS HEADING EASTWARD INTO UNSTABLE AIR. MAIN THREAT DAMAGING WINDS WITH STRONG SPEED SHEAR ACROSS AREA. PREVIOUS DISCUSSION ISSUED AT 415 PM...RATHER COMPLEX UPCOMING FORECAST AS MAIN HEIGHT FALL CENTER WILL BE ACROSS THE ST LAWRENCE VALLEY TODAY... AS SUGGESTED THIS TIME YESTERDAY...MODELS AND CONVECTIVE SCHEMES CONTINUE TO HAVE CHALLENGES THIS MORNING. SATELLITE AND RADAR ANALYSIS THIS MORNING REVEAL A WEAKENING MCS /ACTUALLY A LITTLE SMALLER THAN THE DEFINITION FOR A MCS/ OVER WESTERN NY. PURE EXTRAPOLATION OF THIS COMPLEX WOULD BRING RAIN AND EMBEDDED THUNDER INTO OUR WESTERN 1/3RD OF THE CWA AROUND 10Z AND OUR ADJACENT WESTERN NEW ENGLAND COUNTIES AROUND 12Z. USUALLY WHEN THESE COMPLEXES WEAKEN...SO TOO DOES THE FORWARD PROPAGATION SO THE AFOREMENTIONED TIMES ARE APPROXIMATE AND IF TRENDS CONTINUE. THIS SEEMS TO BE ALONG THE WARM FRONT AND HIGHER THETA-E AIR QUICKLY ADVANCING ACROSS OHIO AND LAKE ERIE. SPC HOURLY MESOSCALE ANALYSIS SUGGESTS PWATS ARE CLOSE TO 2 INCHES WITH MOISTURE TRANSPORT MAGNITUDES AROUND 40KTS. MUCAPES UPSTREAM ARE QUITE HIGH WITH VALUES IN EXCESS OF 3K J/KG WHICH IS PROGGED TO ADVECT INTO PORTIONS OF THE CWA TODAY. PER CLOSE COLLABORATION WITH SPC AND NEIGHBORING WFOS...SLIGHT RISK FOR THE ENTIRE REGION TODAY AHEAD OF COLD FRONT WITH BULK SHEAR VALUES BETWEEN 40-50KTS. THIS HIGHER POTENTIAL INSTABILITY SEEMS TO BE ALONG AND SOUTH OF I90 AND THIS NOTION IS ALSO SUGGESTED FROM THE KF-NAM RUN THIS EARLY THURSDAY MORNING PER SPC DISCUSSION. THEREFORE...ENHANCED WORDING WILL BE PLACE IN THIS REGION AND IN AGREEMENT WITH THE HIGHER PROBABILITY PER SPC SWODY1. NOW...IF ENOUGH INSOLATION WERE TO OCCUR THEN UPDRAFTS COULD BECOME RATHER ROBUST WITH SBCAPES IN EXCESS OF 2K J/KG WITH FORECAST DCAPES BETWEEN 1000-1500 J/KG SUGGEST A STRONG POTENTIAL FOR DAMAGING DOWNDRAFTS. FROPA TIMING FROM THE NCEP MODEL SUITE AND EXPERIMENTAL RUC SUGGEST AROUND 20Z FOR OUR SOUTHEAST ZONES. IN THE WAKE OF THE FROPA...TRENDS IN THE FORECAST WIND FIELD HAS WEAKENED AND PREVIOUS GUSTS IN THE MOS NUMBERS HAS COME DOWN. NEVERTHELESS...PRESSURE RISES AND MIXING LAYER HEIGHTS SUGGEST AT LEAST 30KT POTENTIAL LATE THIS AFTERNOON. TEMPERATURES WILL ALSO BE A CHALLENGE WITH A BLEND OF LAV/MET/MAV AT THIS TIME /LOW-MID 80S IN THE HUDSON RIVER VALLEY AND 70S FOR THE TERRAIN/. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... THOSE AFOREMENTIONED WINDS WILL SUBSIDE THIS EVENING AS THE SURFACE GRADIENT RELAXES AS HIGH PRESSURE BUILDS IN FROM THE WEST DESPITE THE REGION STILL EMBEDDED WITHIN THE NORTHWEST FLOW ALOFT THROUGH FRIDAY NIGHT. THIS WILL KEEP THE REGION NEARLY PRECIP FREE...WITH THE EXCEPTION OF THE HIGHER TERRAIN ON FRIDAY. WITH DAYTIME HEATING AND RESIDUAL GROUND MOISTURE...THERE IS A SLIGHT CHANCE FOR A POPUP SHOWER AND WILL RETAIN THE PREVIOUS FORECAST. TIMING OF NEXT UPSTREAM MCS DEVELOPMENT SEEMS TO HOLD OFF UNTIL AFTER THE SHORT TERM PERIOD PER MODEL DIAGNOSTICS. MACHINE MOS NUMBERS LOOK RATHER CLOSE AND A BLEND WITH OUR PREVIOUS OFFICIAL FORECAST LOOK GOOD. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... A WEAK HIGH OVER THE REGION FRIDAY NIGHT MOVES OFF SHORE ON SATURDAY AS A FRONTAL SYSTEM DROPS SOUTH INTO THE REGION. THE FRONT THEN STALLS OVER THE REGION SATURDAY NIGHT AS A LOW MOVES ACROSS THE REGION. ON SUNDAY THE FRONTAL BOUNDARY SURGES NORTH AS A WARM FRONT AS A STRONGER LOW PRESSURE AREA MOVES ACROSS THE GREAT LAKES REGION...THEN A COLD FRONT MOVES ACROSS THE REGION MONDAY AS THE LOW MOVES FROM JUST NORTH OF LAKE CHAMPLAIN INTO THE MARITIMES. THAT IS FOLLOWED BY THE UPPER TROF DROPPING INTO THE REGION TUESDAY NIGHT AND SLOWLY MOVING ACROSS THE REGION ON WEDNESDAY. ALL IN ALL...A RATHER DISMAL AND CLOUDY PERIOD WITH SEVERAL BOUTS OF SHOWERS. FOR THE MOST PART WE HAVE CHANCE POPS AND HAVE STUCK WITHIN A FEW DEGREES OF GMOS FOR THE MAX AND MIN TEMPS. THE GFS AND EURO DIFFER SO CONFIDENCE IS FAIRLY LOW...AND WE HAVE MASSAGED POPS TO BETTER FIT IN WITH ADJACENT SECTORS AND ALSO LOWERED POPS FROM LIKELY TO CHANCE DUE TO LOW CONFIDENCE. FOR THE MOST PART HIGH TEMPS DURING THIS PERIOD RANGE FROM THE HIGH 60S IN COOLER AREAS LIKE THE ADIRONDACKS AND SOUTHERN VERMONT TO THE LOW AND MID 80S IN THE HUDSON VALLEY...THEN COOL TO THE MID 60S AND MID 70S ON WEDNESDAY WITH THE UPPER LOW. LOW TEMPS RANGE FROM THE UPPER 40S TO THE LOWER 60S. && .AVIATION /15Z THURSDAY THROUGH MONDAY/... SEVERE THUNDERSTORM WATCH #404 IS IN EFFECT UNTIL 22Z/THURSDAY FOR KGFL...KALB AND KPOU. MAINLY VFR CONDITIONS EXPECTED TODAY WITH MVFR-IFR WITH SHOWERS AND THUNDERSTORMS AS THEY MOVE THROUGH. THUNDERSTORM THREAT IS ADDRESSED WITH CB IN TAFS AT THIS TIME UNTIL GET A BETTER HANDLE ON TIMING. STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED WITH THE BEST CHANCES MAINLY SOUTH OF THE CAPITAL DISTRICT. WITH THE PASSAGE OF THE COLD FRONT A DRIER AND COOLER AIRMASS WILL FILTER IN TONIGHT. HOWEVER.. WITH WINDS DIMINISHING AND RESIDUAL LOW LEVEL MOISTURE THERE IS THE POSSIBILITY OF RADIATION FOG AND/OR LOW STRATUS DURING THE NIGHT TONIGHT. OUTLOOK... FRI...VFR...NO SIG WX. SAT-MON...VFR WITH MVFR POSSIBLE WITH A CHANCE SHRA/-TSRA. && .FIRE WEATHER... NEAR WET FLAG CONDITIONS EXPECTED TODAY WITH SHOWERS AND THUNDERSTORMS EXPECTED. DRIER AND COOLER CONDITIONS SETTLE INTO THE REGION LATE TODAY ON GUSTY NORTHWEST WINDS...THEN THOSE WINDS WILL SUBSIDE AND DRY CONDITIONS WILL LAST THROUGH FRIDAY. RELATIVE HUMIDITIES WILL AVERAGE BETWEEN 50 AND 70 PERCENT TODAY...BETWEEN 90 AND 100 PERCENT TONIGHT...THE DRY OUT BETWEEN 30 AND 40 PERCENT ON FRIDAY. && .HYDROLOGY... HIGHER MOISTURE CONTENT WILL ADVECT INTO THE REGION TODAY WITH AN INCREASE COVERAGE OF SHOWERS AND THUNDERSTORMS. THUNDERSTORMS MAY CONTAIN LOCALLY HEAVY DOWNPOURS POSSIBLY PRODUCING ISOLATED AMOUNTS OF 1 TO 2 INCHES. BASIN AVERAGES ARE EXPECTED REMAIN UNDER 1 INCH...WHICH IS WELL BELOW FLASH FLOOD GUIDANCE...AT THE PRESENT TIME. FURTHERMORE...WITH RIVERS FLOWS NEAR NORMAL TO BELOW NORMAL...WE ARE NOT EXPECTING FLOODING ON THE MAIN STEM RIVERS AT THIS TIME. HOWEVER...RAPID RISES ON SMALL STREAMS AND PONDING OF WATER ON ROADS AND IN PARKING AREAS/POOR DRAINAGE COULD BE ISSUES WHERE THUNDERSTORMS PRODUCE HEAVY DOWNPOURS.
