NWS Albany, NY wrote its last area forecast discussion before the first event at May 4, 12:54 PM EST, 2 hours 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 154 PM EDT TUE MAY 4 2010 .SYNOPSIS... AN APPROACHING FRONTAL BOUNDARY WILL BRING SHOWERS AND SOME THUNDERSTORMS TO THE REGION THIS AFTERNOON. IN THE WAKE OF THIS FRONTAL BOUNDARY...WEAK HIGH PRESSURE WILL CROSS THE AREA TONIGHT. A WARM FRONT WILL LIFT NORTHWARD ON WEDNESDAY WITH AN INCREASINGLY SOUTHERLY WIND. MORE SHOWERS AND A FEW THUNDERSTORMS RETURN OVERNIGHT WEDNESDAY INTO EARLY THURSDAY AS A COLD FRONT TRACKS ACROSS NEW ENGLAND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... AS OF 150 PM EDT...SEVERE THUNDERSTORM WATCH 139 HAS BEEN ISSUED FOR THE ENTIRE CWA. MAIN BATCH OF SHRA/TSRA NOW ACROSS WESTERN DACKS/WESTERN MOHAWK VALLEY. THESE STORMS HAVE A HISTORY OF SMALL HAIL AND WIND DAMAGE...INCLUDING A MEASURED GUST TO 55 KTS AT KSYR. WILL EXPECT DAMAGING WINDS TO BE THE MAIN THREAT WITH THIS CONVECTION AS IT RAPIDLY MOVES EASTWARD ACROSS THE DACKS/MOHAWK VALLEY/AND EVENTUALLY THE LAKE GEORGE SARATOGA REGION. SOUTHERN AREAS SEEM TO HAVE MORE SUN AND BETTER CAPE AT THE MOMENT...BUT BEST DYNAMICAL FORCING APPEARS TO BE IN THE AFOREMENTIONED NORTHERN AREAS DUE TO A STRONG SHORTWAVE. STILL CAN/T RULE OUT DAMAGING GUSTS IN ANY POP UP STORMS FOR THE SOUTHERN AREAS...WHICH IS WHY THE ENTIRE CWA HAS BEEN INCLUDED IN THE WATCH. PREVIOUS DISCUSSION IS BELOW... AS OF 1145 AM EDT...SCATTERED TO NUMEROUS SHOWERS HAVE DEVELOPED ACROSS MUCH OF THE WESTERN AND SOUTHERN ADIRONDACKS...WITH MUCH MORE ISOLATED SHOWERS OCCURRING FURTHER S. A SMALL CLUSTER OF SHOWERS AND TSTMS ALSO WAS OCCURRING ACROSS CENTRAL NYS...JUST AHEAD OF SHORTWAVE TROUGH AXIS APPROACHING FROM THE EASTERN GREAT LAKES. OVER THE NEXT FEW HOURS...WE EXPECT NUMEROUS SHOWERS AND ISOLATED TSTMS TO DEVELOP/PERSIST ACROSS THE SOUTHERN DACKS...AND SHOULD EXPAND E INTO SOUTHERN VT. FURTHER S...ADDITIONAL ISOLATED TO SCATTERED SHOWERS SHOULD ALSO DEVELOP. GIVEN LOW WBZ HEIGHTS DROPPING TO 7000-8000 FT AGL THIS AFTERNOON...ANY TALLER SHOWERS/TSTMS WILL BE CAPABLE OF PRODUCING SMALL HAIL/GRAUPEL...ALONG WITH GUSTY WINDS IN EXCESS OF 35 MPH. HOWEVER...THE ABUNDANCE OF CLOUD COVER SHOULD LIMIT THE OVERALL INSTABILITY TO PREVENT STORMS FROM BECOMING SEVERE. ADDITIONALLY...OUR REGION WILL INCREASINGLY BECOME LOCATED WITHIN THE LEFT ENTRANCE REGION OF STRONG JET MAX...WHICH WILL TRANSLATE FURTHER S/E THIS AFTERNOON. THIS MAY ALLOW FOR SOME ENHANCED SUBSIDENCE/STRENGTHENING MID LEVEL CAP TO PREVENT SHOWERS/TSTMS FROM BECOMING SEVERE AS WELL. OVERALL...ONLY MINOR TWEAKS TO ONGOING FORECAST TO ACCOUNT FOR RECENT TEMP/DEWPOINT TRENDS. PREVIOUS DISCUSSION FOLLOWS... AS OF 4 AM...SHORT WAVE TROUGH AXIS WAS TRACKING ACROSS THE CENTRAL GREAT LAKES REGION WITH A SOMEWHAT DIFFLUENT PATTERN DOWNSTREAM AS 150KT 300MB JET WAS WITHIN THIS DOWNSTREAM SOUTHWEST FLOW REGIME. RADAR MOSAIC REVEALS A LINE OF SCT SHOWERS EXTENDING FROM WESTERN NY SOUTHWEST INTO THE OHIO RIVER VALLEY AND WHEN EXTRAPOLATING THE TIME OF ARRIVAL...OUR WESTERN CWA AROUND 15Z...HUDSON RIVER VALLEY AROUND 16Z AND ADJACENT WESTERN NEW ENGLAND 17-18Z. WITH SOME INSOLATION EXPECTED...TEMPERATURES SHOULD QUICKLY REBOUND THROUGH THE 60S THIS MORNING. HOWEVER...DEWPOINTS APPEAR RATHER LOW WITH VALUES INTO THE MIDDLE 40S TO AROUND 50F. MODIFIED FORECAST PROFILES REVEAL CAPES LESS THAN 1K J/KG AND RATHER SKINNY CAPE DENSITY. A CLOSE EXAMINATION DOES REVEAL STEEPENING LAPSE RATES WITH -20 TO -24C AT 500MB THROUGH THE DAY WITH INVERTED-V SIGNATURES TO WARRANT THE CONTINUED THREAT FOR SMALL HAIL AND GUSTY WINDS. AS SEEN UPSTREAM WITH SEVERE REPORTS...CAN NOT RULE OUT 1-2 MORE ROBUST UPDRAFTS TO PRODUCE A SEVERE EVENT. AFTER COLLABORATION WITH SPC THIS MORNING...FEEL THREAT IS RATHER LOW TO PRECLUDE SLIGHT RISK MENTION AND KEEP THE REGION WITHIN A "SEE TEXT". THERE WILL BE A WINDOW OF OPPORTUNITY THIS AFTERNOON FOR ANOTHER EPISODE OF STRONG WINDS AS MIXING LAYER HEIGHT FORECASTS WE MAY TAP INTO 30KT WINDS AGAIN WITH FROPA. COMPARED TO THE PAST COUPLE OF DAYS...HIGH TEMPS WILL RANGE FROM LOWER-MID 70S FOR THE HUDSON RIVER VALLEY INTO NW CT WITH MID TO UPPER 60S ELSEWHERE. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... SURFACE AND UPPER LEVEL TROUGH EXITS RATHER QUICKLY TO THE EAST EARLY THIS EVENING BEING REPLACED WITH A ANTICYCLONIC FLOW PATTERN. A TRANQUIL NIGHT WITH MOCLR SKIES AS TEMPERATURES DROP BACK INTO THE 40S...30S FOR THE ADIRONDACKS. A POWERFUL PACIFIC JET HAS COME ASHORE AND WILL EJECT OUT INTO THE CENTRAL AND NORTHERN PLAINS. BY WEDNESDAY...THIS WILL ALLOW FOR THAT COLD FRONT TO RETURN BACK AS A WARM FRONT AND LIFT NORTH THROUGH THE DAY. THIS WILL BRING ABOUT WARM ADVECTION AND THOSE WARMER SURFACE TEMPERATURES BACK THROUGH THE 70S. QUESTION WILL BE IF SHOWERS WILL DEVELOP WITHIN THE REGION OF STRONGER WARM ADVECTION AS DEPICTED BY THE NAM12. FOR NOW...WE WILL REFRAIN FROM MENTIONING OF PRECIP AND AWAIT FOR TRENDS TO BECOME MORE SOLIDIFIED. THIS PACIFIC SYSTEM WILL APPROACH WEDNESDAY NIGHT AND HERE IS WHERE THE MODELS BEGIN TO SHOW SOME TIMING DIFFERENCES. THE NAM IS THE SLOWEST PER THE NCEP MODEL SUITE WITH OTHER VARIOUS GLOBAL MODELS REVEALING A FASTER AND MORE PROGRESSIVE FEATURES. FEEL THIS IS MORE PRUDENT PER HPC DISCUSSION AND UPSTREAM TRENDS. THIS WILL BRING A RATHER STRONG COLD FRONT ACROSS THE REGION WEDNESDAY NIGHT. SHOWALTER INDICES DEPICT VALUES AOA 0C WITH FAVORABLE ENTRANCE REGION DYNAMICS OF UPPER JET COINCIDING WITH 40-50KT LOW LEVEL JET. AT THIS TIME...WILL INCREASE POPS BUT NOT TO THE EXTENT OF LIKELY VALUES SINCE TIMING OF FEATURES IS NOT COMPLETELY SOLIDIFIED. COLD ADVECTION WILL BE IN FULL SWING THURSDAY AS THOSE 850MB TEMPS DROP BACK DOWN INTO THE LOWER SINGLE DIGITS BY DAYS END WITH HIGH TEMPS A GOOD 5 TO 10 DEGREES COOLER WEST OF THE HUDSON RIVER /FURTHER EAST SOME ASSISTANCE OF DOWNSLOPING WILL KEEP TEMPERATURES INTO THE MIDDLE 70S FOR THE VALLEY AND PORTIONS OF NW CT/. FURTHERMORE...STRONG WEST- NORTHWEST WINDS ARE EXPECTED AS EFFECTIVE MIXING LAYER HEIGHTS SUGGEST AT LEAST 30KTS...PERHAPS EVEN HIGHER. LASTLY...WITH THE COLD ADVECTION OVER THE WARM WATERS OF LAKE ONTARIO...POTENTIAL FOR SOME LAKE EFFECT RAIN SHOWERS DOWNWIND INTO PORTIONS OF THE ADIRONDACKS AND WILL PLACE SLIGHT CHANCE POPS AT THIS TIME. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... PER NCEP MODEL DISCUSSION...ELECTED TO INITIALIZE THE GRIDS FOR MOST OF THIS PERIOD WITH HPC GUIDANCE. FRONTAL SYSTEM THAT MOVES THRU THE REGION THURSDAY STALLS OVER THE MID ATLANTIC REGION AS A WEAK RIDGE OF HIGH PRESSURE WEDGES ITS WAY SOUTHEAST FROM CENTRAL CANADA INTO THE REGION THURSDAY NIGHT WITH DRY WEATHER AND SEASONABLE LOWS. ON FRIDAY ANOTHER OF A SERIES OF DISTURBANCES MOVES FROM THE SOUTHERN PLAINS TO THE CENTRAL GREAT LAKES REGION...SPREADING CLOUDS AND PRECIP NORTH AND EAST INTO THE REGION...AS AN UPPER TROF PROGRESSES EAST INTO THE WESTERN GREAT LAKES. THE LOW BECOMES VERTICALLY STACKED AS THE TROF AND CUTOFF SHIFT EAST TO LAKE ONTARIO BY MIDDAY SATURDAY AND THE CUTOFF LIFTS OUT TO THE NORTHEAST DOWN THE ST. LAWRENCE VALLEY...OPENING THE WAY FOR MUCH COLDER AIR TO FLOW INTO THE REGION FROM NORTHEASTERN CANADA AROUND THE WEST SIDE OF THE UPPER LOW. ON FRIDAY NIGHT WE WILL BE LOOKING AT A CHANCE FOR SOME CONVECTION IN OUR SOUTHERN COUNTIES WITH SOME LOW VALUES OF CAPE. BEING IN DAY 4/5 WE HAVE KEPT POPS IN THE CHANCE CATEGORY. HIGHS FRIDAY...LOW 50S TO LOW 70S...LOWS FRIDAY NIGHT IN THE 40S AND 50S...WITH HIGHS SATURDAY FROM THE UPPER 40S TO NEAR 70. ON SATURDAY NIGHT LOWS DIP INTO THE UPPER 20S ACROSS THE ADIRONDACKS...WITH LOWS NEAR 40 IN THE WARMER HUDSON AND HOUSATONIC VALLEYS. SUNDAY WILL BE CLOUDY...BLUSTERY...AND COLD...WITH HIGHS FROM THE MID 40S NORTH TO THE UPPER 50S SOUTH. LOWS SUNDAY NIGHT WILL BE FROM THE UPPER 20S TO THE MID 30S... WHICH WOULD BE MORE TYPICAL OF MID APRIL. WITH PARTIAL SUNSHINE TEMPERATURES WILL REBOUND SOME ON MONDAY WITH HIGHS FROM THE LOWER 50S ACROSS THE ADIRONDACKS AND SOUTHERN VERMONT TO THE LOW 60S IN THE HUDSON VALLEY FROM ALBANY SOUTH. BOTH THE GFS AND THE ECMWF SHOW THE AREA OF MAXIMUM PRECIPITATION ACROSS THE WESTERN AND CENTRAL ADIRONDACKS WITH TOTALS OF 1.5 TO 2.5 INCHES...SOME OF WHICH COULD POSSIBLY COME AS WET SNOW ON SATURDAY NIGHT ESPECIALLY TO AREAS ABOVE ELEVATIONS OF 2000 FEET. && .AVIATION /18Z TUESDAY THROUGH SATURDAY/... CONVECTION DEVELOPING ACROSS WESTERN PARTS OF THE AREA WILL HEAD TOWARDS THE HUDSON VALLEY TERMINALS FOR THE MID TO LATE AFTN HOURS. THIS MAY ALLOW FOR A BRIEF AND LOCALIZED WIND GUST UP TO 40 KTS AT THE ONSET OF THE STORMS...ESP AT KGFL...WHERE THE BULK OF THE CONVECTION LOOKS TO BE AIMED FOR. WILL ALLOW FOR A TSTORM AT ALL TERMINALS USING A TSRA OR VCTS THROUGH 22Z. CONDITIONS MAY BRIEFLY BECOME MVFR/IFR AT ANY LOCATION WITHIN ANY SHOWER/TSTORM. AFTERWARD...THE FRONT WILL PASS THROUGH AND SHOULD ALLOW FOR DECREASING CLOUDS AND A RETURN TO VFR CONDITIONS AT ALL TERMINALS. WINDS WILL BE GUSTY THROUGH THE EVENING HOURS...BEFORE BECOMING LIGHT AND VARIABLE FOR THE OVERNIGHT HOURS. SKIES WILL CLEAR OUT FOR THE OVERNIGHT HOURS AS WELL...WITH ONLY SCT ALTOCU EXPECTED ON WEDNESDAY...ALONG WITH FAIRLY LIGHT WINDS. OUTLOOK... TUE NT-WED...VFR. NO SIG WX. THU..VFR...CHC MVFR ASSOC WITH SCT -SHRA/-TSRA. FRI...VFR/MVFR. CHC AFTERNOON -RA FRI NT-SAT...MVFR/IFR...CHC -RA. && .FIRE WEATHER... SHOWERS AND A FEW THUNDERSTORMS WILL OCCUR TODAY AS A FRONTAL BOUNDARY AND ASSOCIATED UPPER AIR DISTURBANCE CROSS THE REGION. WITH CLOUD COVER...EXPECTED MINIMUM RELATIVE HUMIDITIES WILL RANGE BETWEEN 35 AND 55 PERCENT. THE LOWER VALUES ARE EXPECTED INTO PORTIONS OF THE MID HUDSON RIVER VALLEY AND NORTHWEST CONNECTICUT. WESTERLY WINDS WILL INCREASE LATER TODAY WITH GUSTS TO NEAR 30 MPH EXPECTED. IMPROVING CONDITIONS TONIGHT WITH A WEAK RIDGE OF HIGH PRESSURE. WITH SOME EARLIER RAINFALL CAUSING WET GROUNDS...RELATIVE HUMIDITIES TONIGHT SHOULD RANGE BETWEEN 80 AND 100 PERCENT. WARM FRONT LIFTS NORTH ON WEDNESDAY WITH WARMER TEMPERATURES AND LOWER HUMIDITY VALUES...GENERALLY BETWEEN 20 AND 40 PERCENT. && .HYDROLOGY... NO PROBLEMS ARE ANTICIPATED ON THE RIVERS OVER THE NEXT FEW DAYS WITH STREAM AND RIVER FLOWS REMAINING BELOW TO WELL BELOW NORMAL FOR THIS TIME OF YEAR. THE MOST RECENT STORM BROUGHT RAINFALL OF A QUARTER INCH TO HALF INCH TO OUR SOUTHERN COUNTIES WHICH RESULTED IN A VERY MINOR RESPONSE ON THE RIVERS. FARTHER NORTH RAINFALL WAS VERY LIGHT WITH VERY LITTLE EFFECT ON THE RIVERS. SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR THIS AFTERNOON BUT MOISTURE IS LIMITED AND RAINFALL SHOULD AMOUNT TO LESS THAN A QUARTER INCH...AND THUS IT WILL HAVE VERY LITTLE EFFECT ON THE RIVERS. A MORE WIDESPREAD RAINFALL EVENT IS POSSIBLE FRIDAY INTO SATURDAY WHICH MAY PRODUCE OVER AN INCH OR RAIN AND CAUSE SOME RISES ON AREA STREAMS AND RIVERS.
