NWS Albany, NY wrote its last area forecast discussion before the first event at Jul 4, 1:05 PM EST, 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 205 PM EDT MON JUL 4 2011 .SYNOPSIS... DRIER AIR WAS IN THE PROCESS OF MOVING ACROSS THE REGION...WITH A CLUSTER OF SHOWERS AND STORMS NEAR LAKE GEORGE. THAT CLUSTER WILL MOVE NORTHEAST WHILE OTHER AREAS SHOULD REMAIN DRY. HIGH PRESSURE WILL BUILD TONIGHT AND TOMORROW WITH FINE SUMMER WEATHER. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... AS OF 130 PM...FOLLOWING A CLUSTER OF SHOWERS AND STORMS NEAR LAKE GEORGE. THESE MIGHT HAVE FORMED OFF THE LAKE BREEZE BOUNDARY OFF ONTARIO. THERE WAS ALSO A DEWPOINT DISCONTINUITY IN THIS REGION WITH DEWPOINTS AROUND 65 NEAR KGFL...DOWN INTO THE 50S TO THE WEST OF THE BOUNDARY. THE HIGH RESOLUTION RAPID REFRESH (HRRR) AS WELL AS THE LATEST NAM INDICATES ANY CONVECTIVE ACTIVITY SHOULD BE CONFINED TO OUR NORTHEAST AREAS AND THUS FAR...THAT'S WHAT WE HAVE SEEN. SO CONFINE POPS TO THESE REGIONS THROUGH SUNDAY. AFTER THAT...ANY CONVECTION SHOULD BE FINISHED AND WE BE LEFT WITH A CLEAR COMFORTABLY COOL NIGHT. SAW NO REASON TO TINKER WITH HIGH TEMPS THIS AFTERNOON...SO LEFT THEM IN TACT. ************PREVIOUS NEAR TERM DISCUSSION************ AS OF 1030 AM...OUTSIDE OF HOURLY ADJUSTMENTS...WATCHING CLOSELY CONVECTIVE POTENTIAL THIS AFTERNOON. HOURLY HRRR/RUC13 ALONG WITH OUR 12Z SOUNDINGS AND SURFACE ANALYSIS REVEALS THE BEST POTENTIAL FOR CONVECTION WILL GENERALLY BE ALONG AND EAST OF THE HUDSON RIVER. SLOW MOVING FRONTAL BOUNDARY CONTINUES TO SLIDE EAST AS A WEAK SHORT WAVE TROUGH...PER THE H2O VAPOR LOOP...WAS APPROACHING FROM THE EASTERN GREAT LAKES. SURFACE DEWPOINTS WERE IN THE MID 60S EAST OF THIS FRONTAL BOUNDARY AND COMBINING THAT WITH EXPECTED HIGH TEMPS INTO THE 80S YIELDS SBCAPES BETWEEN 1000-1500 J/KG. HOWEVER...AS SEEN IN THE BUF SOUNDING....DRY AIR WILL CONTINUE TO ENCROACH. PER THE EXPERIMENTAL REFLECTIVITIES...WE WILL PLACE THE HIGHER POPS FOR PORTIONS OF WASHINGTON COUNTY...DOWN INTO THE TACONICS...BERKS...SOUTHERN GREENS THIS AFTERNOON. IF THESE CELLS DO DEVELOP...PROPAGATION VECTORS WOULD POINT TOWARD NW CT LATE THIS AFTERNOON MAINLY FOR THE HILLS. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... SURFACE HIGH PRESSURE BUILDS IN TONIGHT WITH HEIGHTS RISING SOME ALOFT WITH THE FLOW BECOMING ZONAL ALONG THE UNITED STATES CANADA BORDER BY TUESDAY MORNING. THE RIDGES INFLUENCE WILL BE SHORT LIVED AS ANOTHER LOW PRESSURE WILL IMPACT THE REGION MID WEEK. TUESDAY LOOKS DRY WITH COMFORTABLE DEW POINTS IN THE 50S AND A LIGHT WESTERLY WIND. MODEL GUIDANCE IS IN AGREEMENT THAT A SHORT WAVE WILL MOVE THROUGH THE FAST ZONAL FLOW ON THE SOUTHERN PERIPHERY OF AN EASTERN CANADA UPPER TROUGH SPINNING UP A LOW PRESSURE SYSTEM AND RETURNING THE LONGWAVE TROUGH TO THE NORTHEASTERN UNITED STATES. CONVECTION WILL ACCOMPANY THE SYSTEM AS IT MOVES THROUGH. THE STORM PREDICTION CENTER HAS NORTHERN NEW YORK STATE IN A "SEE TEXT" FOR SEVERE STORMS WEDNESDAY AFTERNOON AND EVENING INDICATING FAVORABLE VERTICAL SHEAR AND POTENTIAL INSTABILITY. WILL HAVE MENTION OF THREAT IN OUR HAZARDOUS WEATHER OUTLOOK. && .LONG TERM /THURSDAY THROUGH SUNDAY/... THE FRONTAL SYSTEM APPEARS TO STALL JUST SOUTH AND EAST OF THE REGION THURSDAY...WITH A SURFACE LOW DEVELOPING ALONG THE FRONTAL BOUNDARY IN THE MID ATLANTIC STATES ALONG WITH A BROAD UPPER TROF MOVING ACROSS THE REGION. THE GFS COMES UP WITH SOME RATHER LARGE MUCAPE VALUES OF 1500 TO 4000 J/KG SOUTH OF ALBANY. THESE VALUES ARE PROBABLY A BIT ON THE HIGH SIDE. ECMWF SURFACE BASED CAPES OF 1000 TO 2000 J/KG LOOK TO BE MORE IN THE BALL PARK. EITHER WAY...WE HAVE GONE WITH CHANCE POPS FOR SHOWERS AND THUNDERSTORMS ACROSS THE FORECAST AREA FOR THURSDAY...THEN BACK THEM TO SLIGHT CHANCE FOR THURSDAY NIGHT. PWAT VALUES NOT PARTICULARLY IMPRESSIVE...MOSTLY 1.0 TO 1.5 INCHES. QPF AMOUNTS ON THE MODELS AND FROM HPC NOT VERY IMPRESSIVE EITHER. HIGHS THURSDAY WILL RANGE FROM THE MID 70S ACROSS THE ADIRONDACKS TO THE UPPER 80S IN THE HUDSON VALLEY SOUTH OF ALBANY...WHERE IT MAY GET A BIT ON THE SULTRY SIDE WITH DEWPOINTS FROM THE UPPER 60S TO NEAR 70. AS NORTHERLY WINDS BRING COOLER AND DRIER AIR INTO THE NORTHWESTERN PART OF OUR REGION...LOWS WILL DIP INTO THE LOW 50S AND A FEW UPPER 40S ACROSS HIGHER ELEVATIONS OF THE ADIRONDACKS AND SOUTHERN VERMONT. IN THE HUDSON VALLEY LOWS WILL BE IN THE LOW AND MID 60S. ON FRIDAY...A LOW MOVING ALONG THE FRONT WILL PROBABLY NOT GET FAR ENOUGH NORTH AND WEST TO IMPACT THE REGION...BUT THERE IS AN OUTSIDE CHANCE OF A FEW SHOWERS AND EVEN A THUNDERSTORM OR TWO. MORE THAN LIKELY THE SHOWERS...AND MOST OF THE CLOUDS...WILL REMAIN SOUTH OF OUR REGION. HIGHS FRIDAY WILL RANGE FROM THE UPPER 70S TO THE MID 80S. IT WILL BE MOSTLY CLEAR AND PLEASANT FRIDAY NIGHT...WITH LOWS FROM AROUND 50 ACROSS THE HIGHER TERRAIN TO THE LOW 60S IN THE HUDSON VALLEY. ON SATURDAY...A 500 HPA RIDGE MOVES INTO THE REGION FROM THE WEST WHICH WILL CONTINUE THE MOSTLY SUNNY AND DRY WEATHER FOR THE WEEKEND WITH NEAR SEASONABLE TEMPERATURES. HIGHS WILL BE FROM THE UPPER 70S TO THE MID 80S AND LOWS IN THE 50S AND LOWER 60S. THE NORMAL HIGH FOR ALBANY AT THIS TIME OF YEAR IS 82 AND THE NORMAL LOW IS 60. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... AT 1715Z...WEAK COLD FRONTAL BOUNDARY WAS TOUCHING OFF AN ISOLATED POPCORN RAIN SHOWER CB...MIGRATING VERY SLOWLY SE NORTH OF KGFL AT WESTERN EDGE OF LARGE AREA OF VERY HIGH SFC CAPES THAT EXTENDED THROUGH NORTHERN NEW ENGLAND. INCREASING DRYNESS AND CAPPING IS EXPECTED TO LIMIT DEVELOPMENT BEYOND ISOLD RW WITH THE OUTSIDE POSSIBILITY OF THUNDER UNTIL SUNDOWN IN VCNTY OF KGFL. CAPES AND MOISTURE MUCH LOWER AT KALB AND KPOU SHOULD NEGATE ANY ACTIVITY THERE. WITH CELLS GONE THIS EVENING...FOCUS TURNS TO FOG. WEAK COLD FRONT PASSING THROUGH THIS EVENING WILL LIMIT DEGREE OF DRY AIR INFILTRATION...RESULTING IN ONLY WEAK SFC WINDS. THIS...COUPLED WITH CLR TO PTLY CLOUDY SKIES...WILL RESULT IN DECENT RADIATIONAL COOLING...TO BRING ABOUT SOME MAINLY MVFR FOG OVERNIGHT AS DEWPOINTS STRUGGLE TO KEEP UP WITH THE TEMPERATURE DROP. KGFL COULD SEE A BRIEF PERIOD OF IFR FOG WITH A COOLER OVERNIGHT LOW TEMP EXPECTED THERE. CLOUDS WILL BE LITTLE MORE THAN SCT...AND WELL INTO THE VFR RANGE ON TUE. WINDS WILL REMAIN LIGHT ON TUESDAY WITH A LIGHT UPPER-LEVEL WIND PROFILE...MAKING FOR IDEAL FLYING. OUTLOOK... TUE PM-WED AM...MAINLY VFR...WITH LCL MVFR NIGHTTIME FOG PSBL KGFL.

CAN NOT COMPLETELY RULE OUT THE CHANCE FOR ISOLATED STORMS ACROSS THE AREA THIS AFTERNOON...AS A DISTURBANCE IN THE UPPER LEVELS OF THE ATMOSPHERE MOVES OVER THE REGION. HIGH PRESSURE WILL BUILD IN TONIGHT AND DOMINATE TUESDAY. ANOTHER LOW PRESSURE SYSTEM WILL APPROACH AND MOVE ACROSS THE REGION MID WEEK BRINGING CHANCES FOR STORMS WEDNESDAY AND THURSDAY. MINIMUM RELATIVE HUMIDITY VALUES WILL BE MAINLY IN THE 30S THIS AFTERNOON AND TUESDAY AFTERNOON WITH A RECOVERY TO 75 TO 90 PERCENT TONIGHT AND TUESDAY NIGHT. && .HYDROLOGY... NO PROBLEMS ARE EXPECTED ON THE RIVERS FOR THE NEXT SEVERAL DAYS. ON SUNDAY...THE HEAVY RAINS MISSED THE WATERSHED ABOVE HINCKLEY RESERVOIR AND ITS WATER LEVEL CONTINUES TO SLOWLY GO DOWN. THE HEAVIEST RAINFALL OCCURRED ACROSS THE EASTERN CATSKILLS AND CAUSED THE LEVEL OF SCHOHARIE RESERVOIR TO GO UP 4 FEET. REFER TO OUR PUBLIC INFORMATION STATEMENT FOR RAINFALL REPORTS. CAN NOT COMPLETELY RULE OUT THE CHANCE FOR ISOLATED STORMS ACROSS THE AREA THIS AFTERNOON...AS A DISTURBANCE IN THE UPPER LEVELS OF THE ATMOSPHERE MOVES OVER THE REGION.
