NWS Albany, NY wrote its last area forecast discussion before the first event at Sep 13, 1:06 PM EST, 1 hour 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 206 PM EDT MON SEP 13 2010 .SYNOPSIS... A FRONTAL SYSTEM WILL BRING PLENTY OF CLOUDS...ALONG WITH SOME SHOWERS AND POSSIBLY THUNDERSTORMS TO THE REGION TODAY. THIS SYSTEM WILL ALLOW COOLER AIR TO RUSH INTO THE REGION FOR THE MIDDLE OF THE UPCOMING WEEK. ANOTHER STORM SYSTEM WILL RETURN THE CHANCE FOR SOME RAIN FOR THE LATER PORTION OF THE WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... UPDATED FOR SEVERE THUNDERSTORM WATCH #655 IN EFFECT UNTIL 00Z/TUESDAY FOR SCHOHARIE...ALBANY...RENSEELAER AND BERKSHIRE COUNTY SOUTHWARD. PREVIOUS DISCUSSION...AREA OF RAIN TRACKING THROUGH THE SOUTHERN ADIRONDACKS SHOULD BE EAST OF THE LAKE GEORGE AREA BY SUNRISE...THEN TRACK THROUGH SOUTHERN VT AND EXIT BY MID MORNING. EDGE OF CLEARING NOT ADVANCING MUCH...AND SOUTHERLY LOW LEVEL FLOW CONTINUES TO ANCHOR LOW LEVEL MOISTURE IN OUR REGION. WEST BOUNDARY LAYER FLOW ALONG A WARM FRONTAL THERMAL GRADIENT SEEMS TO BE THE LEADING EDGE OF THE CLEARING...AND THE EDGE OF CLEARING SHOULD SLOWLY WORK EAST THROUGH THE DAY. HOWEVER...COOLING ALOFT AND THE ADVANCE OF A COLD FRONT PROXIMATE TO THE MIDLEVEL WARMING IS STEEPENING MIDLEVEL LAPSE RATES AROUND THE GREAT LAKES. THERE IS ALSO AN UPPER LEVEL IMPULSE AND LEADING EDGE OF BROAD BOUNDARY LAYER WIND CORE. REGION WILL BE IN LEFT EXIT REGION OF UPPER JET SEGMENT LATER TODAY...AND H5 WINDS INCREASE TO 50 KT OR MORE. SO...EVEN WITH HIGHS IN THE 60S TO LOWER 70S...SOME INSTABILITY...CAPES APPROACHING 1000 J/KG IN SOME AREAS...AND STRONG UPPER DYNAMICS...SHOULD SUPPORT SHOWERS AND THUNDERSTORMS THIS AFTERNOON. SO...EVEN IF CLOUDS BREAK UP AT SOME POINT THIS AFTERNOON...THERE WILL STILL BE LIMITED SUN...ESPECIALLY IN CENTRAL AND EASTERN AREAS. SOME FRONTOGENESIS EXPECTED AS TIGHTENING THERMAL GRADIENT ALONG COLD FRONT WILL PROVIDE ADDITIONAL BOUNDARY LAYER AND LOW LEVEL FORCING. WITH THE STEEPENING MID LEVEL LAPSE RATES...EVEN THOUGH THE CONVECTION SHOULD BE RELATIVELY SHALLOW...UPDRAFTS MAY BE STRONG ENOUGH FOR SOME HAIL...AND WIND FIELDS POSSIBLE STRONG ENOUGH FOR SOME LOCALIZED DAMAGING WINDS. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... LINGERING CONVECTION WILL EXIT THE REGION DURING THE EVENING...AND WEST LOW LEVEL FLOW WILL SPREAD ACROSS THE AREA. BOUNDARY LAYER COOLING WILL TAKE PLACE...AND EVENTUALLY ENOUGH COOLING WILL TAKE PLACE TO SUPPORT LAKE ENHANCED MOISTURE AND SHOWERS. THE BEST CHANCES FOR SCATTERED SHOWERS WOULD BE IN THE WESTERN MOHAWK VALLEY...SCHOHARIE VALLEY AND IN HIGHER ELEVATIONS SUCH AS CATSKILLS...SOUTHERN ADIRONDACKS...SOUTHERN GREEN MOUNTAINS AND BERKSHIRES. STILL...SOME ISOLATED TO SCATTERED SHOWER ACTIVITY POSSIBLE ABOUT EVERYWHERE THROUGH TUESDAY...WITH MAINLY A CHANCE OF SPRINKLES IN VALLEYS. PERIODS OF CLOUDS AND SUN AWAY FROM THE LAKES...WITH THE MOST CLOUDINESS IN AREAS OF HIGH TERRAIN. BASED ON MIXING POTENTIAL...HIGHS IN THE 50S AND 60S TUESDAY AND WEDNESDAY. COULD THERE BE A SNOW FLAKE OR TWO MIXED WITH A RAIN SHOWER IN THE SOUTHERN ADIRONDACKS WEDNESDAY NIGHT? WORTH KEEPING AN EYE ON IT. && .LONG TERM /THURSDAY THROUGH SUNDAY/... THU-FRI...MOST LONG RANGE DETERMINISTIC MODELS AND GEFS SUGGEST SHORTWAVE...CURRENTLY LOCATED OFF CA COAST...MIGRATES E ACROSS PLAINS AND APPROACHES REGION SOMETIME DURING THIS TIME FRAME. SO...HAVE MAINTAINED INCREASING POPS THU...STARTING WITH SLIGHT CHC IN THE MORNING...AND INCREASING TO CHC BY LATE AFTERNOON. HAVE RETAINED CHC POPS FOR THU NT/EARLY FRI...THEN DECREASED FROM NW TO SE BY FRI AFTERNOON...AS EXACT TIMING OF SYSTEM STILL SOMEWHAT UNCERTAIN. AT THE VERY LEAST...CLOUDS MAY LINGER INTO MUCH OF FRI...EVEN IF RAINFALL ENDS. EXPECT MAX TEMPS TO REACH 65-70 THU IN THE VALLEYS...WITH MAINLY 60S ELSEWHERE...WITH MIN TEMPS THU NT/FRI AM MAINLY IN THE 40S TO LOWER 50S. IT SHOULD BE NOTED THAT...FOR THU MAXES...IF RAIN DEVELOPS QUICKER THAN EXPECTED...MAX TEMPS COULD BE MUCH COOLER...PERHAPS ONLY REACHING THE LOWER 60S EVEN ACROSS VALLEY REGIONS...WITH WIDESPREAD 50S ELSEWHERE. FOR FRI...HAVE INDICATED MAX TEMPS MAINLY IN THE 60S...WITH SOME 50S ACROSS HIGHER ELEVATIONS. HOWEVER...SHOULD CLEARING OCCUR FASTER THAN EXPECTED...SLIGHTLY WARMER MAXES ARE POSSIBLE. FRI NT-SAT NT...EXPECT A RATHER COOL FRI NT IN WAKE OF AFOREMENTIONED SYSTEM...WITH WIDESPREAD 40S EXPECTED...ALONG WITH SOME 30S ACROSS NORTHERN AREAS...AND HIGHER ELEVATIONS ACROSS THE CATSKILLS AND WESTERN NEW ENGLAND. THERE IS SOME POTENTIAL FOR EVEN COOLER MIN TEMPS ACROSS THE REGION...ASSUMING CLEARING OCCURS AND WINDS BECOME LIGHT/CALM. FOR SAT...CURRENTLY EXPECT FAIR CONDITIONS...AND POSSIBLY TURNING A BIT MILDER...AS A SW FLOW DEVELOPS AHEAD OF NEXT COLD FRONT APPROACHING FROM THE NW. THIS MAY ALLOW MAXES TO REACH THE 70S IN SOME VALLEYS...WITH MAINLY 60S ELSEWHERE. SOME CLOUDS...AND PERHAPS ISOLATED SHOWERS COULD DEVELOP AHEAD OF...AND WITH POTENTIAL COLD FRONT FOR LATE SAT INTO SAT NT. EXPECT SAT NT/SUN AM TO BE A BIT MILDER THAN FRI NT/SAT AM...WITH MAINLY 40S EXPECTED...ALTHOUGH MINS MAY HOLD IN THE 50S ACROSS SOME VALLEY REGIONS. SUN...UNCERTAINTY INCREASES WITH TIMING OF FRONT...WITH SOME POSSIBILITY OF FRONT TO SLOW ITS SOUTHEAST PROGRESS THROUGH THE REGION...ESP SHOULD HURRICANE IGOR CONTINUE TRACKING ACROSS THE WESTERN ATLANTIC OCEAN...POTENTIALLY ENHANCING THE RIDGING ALONG THE E COAST AND THUS SLOWING DOWN THE FRONT. FOR NOW...HAVE MAINTAINED SOME SLIGHT CHC POPS...ESP ACROSS N/W AREAS. OTHERWISE...FOR MAXES...GENERALLY HAVE INDICATED 65-70 IN MOST VALLEYS...EXCEPT 70-75 ACROSS THE MID HUDSON VALLEY...WITH MAINLY 50S TO LOWER 60S EXPECTED ACROSS HIGHER ELEVATIONS...AND THROUGHOUT THE NORTH COUNTRY. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... HAVE VCSH AND CB TO COVER FOR THE POSSIBILITY OF WIDELY SCATTERED THUNDERSTORMS NOW ON RADAR. OTRW...WE'RE LOOKING AT VFR CIGS...WITH CHC IFR FOG AT KGFL...MVFR AT KALB LATE TONIGHT AS WINDS WILL BE LIGHT AHEAD OF A COLD FRONT. NOT MUCH LOW-LEVEL FLOW...SO LLWS NOT A CONCERN. SFC WINDS WILL PICK UP AGAIN WITH THE FRONTAL PASSAGE AFTER DAYBREAK ON TUESDAY. 10 TO 15 KNOTS WITH GUSTS FROM 20 TO 25 KNOTS ARE LIKELY BY AFTERNOON. OUTLOOK...

A FRONTAL SYSTEM WILL BRING PLENTY OF CLOUDS...ALONG WITH SOME SHOWERS AND POSSIBLY THUNDERSTORMS TO THE REGION TODAY. THIS SYSTEM WILL ALLOW COOLER AIR TO RUSH INTO THE REGION FOR THE MIDDLE OF THE UPCOMING WEEK. ANOTHER STORM SYSTEM WILL RETURN THE CHANCE FOR SOME RAIN FOR THE LATER PORTION OF THE WEEK. TODAY...RH VALUES WILL LOWER TO BETWEEN 55 AND 75 PERCENT WITH SOME SHOWERS AND POSSIBLY A THUNDERSTORM ACROSS THE REGION DURING THE DAY. RH VALUES WILL INCREASE TO 80 TO 100 PERCENT TONIGHT...THEN FALL TO 40 TO 65 PERCENT TUESDAY. SOUTHERLY WINDS OF 5 TO 15 MPH TODAY...WILL BECOME WESTERLY THROUGH TONIGHT. WINDS WILL BE WEST TO NORTHWEST TUESDAY AT 10 TO 20 MPH...WITH SOME GUSTS AROUND 25 MPH. && .HYDROLOGY... NO HYDROLOGY PROBLEMS ARE EXPECTED FOR THE NEXT SEVERAL DAYS. A FRONTAL BOUNDARY AND UPPER LEVEL DISTURBANCE WILL TRACK ACROSS THE REGION TODAY. SHOWERS AND SCATTERED THUNDERSTORMS TODAY COULD PRODUCE A TENTH OF AN INCH OF RAIN IN MANY AREAS...WITH ISOLATED LOCAL AMOUNTS UP TO AN INCH IN ANY STRONG THUNDERSTORMS. THERE WILL BE LITTLE IF ANY IMPACT ON AREA STREAMS AND RIVERS. RIVER LEVELS WILL CONTINUE AT BELOW NORMAL TO NORMAL LEVELS FOR THE MIDDLE OF SEPTEMBER.
