NWS Albany, NY wrote its last area forecast discussion before the first event at May 29, 2:33 PM EST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 333 PM EDT SAT MAY 29 2010 .SYNOPSIS... A WEAK COLD FRONT WILL PASS SOUTH OF THE REGION THIS EVENING END THE THREAT FROM SHOWERS AND THUNDERSTORMS. HIGH PRESSURE WILL BUILD IN FROM THE GREAT LAKES REGION OVERNIGHT THROUGH SUNDAY WITH WARMER AND DRIER WEATHER. A WARM FRONT WILL MOVE ACROSS THE REGION ON MEMORIAL DAY TO BE FOLLOWED BY AN APPROACHING COLD FRONT FROM THE GREAT LAKES REGION LATE IN AFTERNOON INTO THE OVERNIGHT PERIOD WITH INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS. && .NEAR TERM /THROUGH TONIGHT/... MESOSCALE ANALYSIS REVEALS AN AXIS OF CONVERGENCE EXTENDING FROM THE LAKE GEORGE SARATOGA REGION THROUGH THE EASTERN MOHAWK VALLEY AND INTO THE WESTERN CATSKILLS PER THE LAPS/RTMA/SPC ANALYSIS. CONVECTION HAS DEVELOPED ALONG AND EAST OF THIS BOUNDARY WHERE INSTABILITY FACTORS HAVE INCREASED WITH SBCAPES IN EXCESS OF 1000 J/KG WITH SURFACE DEWPOINTS BETWEEN 60-65F. BASED ON EXPERIMENTAL SHORT TERM REFLECTIVITY FORECASTS PER THE HRRR RUC...EXPECT A CONTINUED SCT LINE OF CONVECTION SOUTHEAST OF THE DACKS THROUGH EARLY THIS EVENING...THE FROPA FOR OUR SOUTHEAST ZONES AOA 03Z SUN. THEREFORE...WE WILL KEEP LOW CHANCE/SCT POPS FOR THE SOUTHEAST 2/3RDS OF THE REGION. REMAINDER OF TONIGHT...A WEAK SHORT WAVE /OR TWO/ WILL TRACK SOUTHEAST BUT MINIMAL MOISTURE AND INSTABILITY SHOULD LIMIT ANY PRECIP AND WILL KEEP THE POPS RATHER LOW. A BLEND OF MOS WITH OFFICIAL PREVIOUS FORECAST NUMBERS LOOS GOOD FOR OVERNIGHT LOWS...WITH MAINLY LOW-MID 50S AND SOMEWHAT COOLER MID-UPPER 40S FOR PORTIONS OF THE DACKS. && .SHORT TERM /SUNDAY THROUGH TUESDAY/... A TIGHTENING BAROCLINIC ZONE EVOLVES ACROSS NORTHERN NY AND INTO NEW ENGLAND ON SUNDAY AS WARM FRONTOGENESIS COMMENCES. THE COMBINATION OF MINIMUM MID LEVEL LAPSE RATES...LACK OF ELEVATED INSTABILITY PER THE SHOWALTER VALUES AND NO TRIGGER PER SHORT WAVES SHOULD LIMIT MENTION OF ANY PRECIP. THE EXCEPTION TO THIS WOULD BE THE SOUTHERN GREENS AS WEST-NORTHWEST FLOW WILL AID IN UPSLOPE CONDITIONS WITHIN THIS REGION OF BAROCLINICITY FOR A SLIGHT CHANCE FOR A SHOWER TO DEVELOP. OTHERWISE...A WARMER DAY UNDER A PTSUNNY SKY FOR THE REMAINDER OF THE REGION AS MIXING LAYER HEIGHTS BETWEEN 800-850MB YIELDS MAX TEMPS INTO THE 80S FOR MANY LOCATIONS. THE AFOREMENTIONED MIXING LAYER HEIGHTS ALSO TAPS INTO MID TO HIGH 20KT WINDS AS THESE SHOULD TRANSLATE TO THE SURFACE THROUGHOUT THE DAY. A LITTLE ENHANCEMENT WITH FUNNELING DOWN THE MOHAWK COULD PROVIDE VALUES TO NEAR 30KTS IN THE IMMEDIATE CAPITAL REGION. SUNDAY NIGHT...THE BAROCLINIC ZONE WILL BEGIN TO SLOWLY MOVE NORTH AS MID LEVEL HEIGHT RISES UNFOLDS. WITH THESE HEIGHT RISES...WILL KEEP THE NIGHT DRY AND RELATIVELY MILD. THE REGION IS WELL WITHIN THE WARM SECTOR ON MONDAY AS THOSE 850MB TEMPS CLIMB WELL INTO THE MID TEENS. FURTHERMORE...LOW LEVEL MOISTURE WILL ALSO BE ON THE INCREASE RESULTING A QUITE WARM AND INCREASINGLY HUMID DAY. SEEMS THE MID LEVEL ANTICYLONIC FLOW SHOULD PROHIBIT MUCH CONVECTION. HOWEVER...THERE IS SOME SUBTLE HINTS WITHIN THE NCEP MODEL SUITE OF A SURFACE TROUGH ACROSS THE REGION WHICH MIGHT BE ENOUGH TO TOUCH OFF A SHOWER OR THUNDERSTORM...ESPECIALLY ACROSS THE TERRAIN. PER COLLABORATION WITH NEIGHBORING OFFICES...WE WILL PLACE SLIGHT CHANCE POPS AT THIS TIME. MOISTURE TRANSPORT INCREASES RATHER QUICKLY MONDAY NIGHT THROUGH TUESDAY WITH PWATS INCREASING TO AN AVERAGE OF 1.75 INCHES AHEAD OF A COOL FRONT /NOT MUCH CHANGE IN THERMAL AIRMASS/. INSTABILITY ALSO WILL BE ON THE INCREASE AS SBCAPES CLIMB TO AROUND 1000 J/KG ALTHOUGH CAPE DENSITY IS RATHER MINIMAL AT THIS TIME WITH A MOIST ADIABATIC PROFILE. GIVEN THE HIGH PWATS AND INSTABILITY...WE WILL INCLUDE HIGH LIKELY POPS AND MENTION HEAVY RAINFALL MONDAY NIGHT THROUGH TUESDAY. OVERNIGHT LOWS WILL BE RATHER MILD BUT DAYTIME HIGHS WILL BE THE HIGHEST ON MONDAY AS WE COULD APPROACH 90F. WITH CLOUDS AND EXPECTED PRECIP...COOLER HIGH TEMPERATURES EXPECTED. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... HPC GUIDANCE. WEAK HIGH PRESSURE BEGINS TO TAKE HOLD AT THE START OF THE PERIOD AS A COLD FRONT PUSHES SHOWERS AND THUNDERSTORMS OUT OF THE REGION...PROVIDING A BRIEF RESPITE WEDNESDAY INTO THURSDAY. A WARM FRONT LIFTS THROUGH OUR ZONES THURSDAY NIGHT...KICKING OFF A CHANCE OF SHOWERS. THE FRONT IS ASSOCIATED WITH LOW PRESSURE WHICH WILL TRACK FROM THE COLORADO ROCKIES TO SOUTHERN QUEBEC FROM TUESDAY NIGHT THROUGH FRIDAY. THE MAIN COLD FRONT SHOULD SET OFF SHOWERS AND THUNDERSTORMS ON FRIDAY AS IT BEGINS TO SLIDE SOUTHEAST ACROSS THE OUR FORECAST AREA. THE SHOWERS WILL CONTINUE INTO FRIDAY NIGHT...BUT STABILITY WILL BE ON THE RISE...AND THE THUNDERSTORMS SHOULD DIMINISH. WITH ANOTHER LOW APPROACHING FROM IOWA ON SATURDAY...SLIGHT CHC POPS CONTINUE INTO THE EARLY PART OF THE WEEKEND. HIGH TEMPERATURES FROM AROUND 70 DEGREES IN THE ADIRONDACKS...TO THE MID 80S IN THE MID HUDSON VALLEY ON WEDNESDAY WILL BACK DOWN ABOUT 5 TO 10 DEGREES BEHIND THE DEPARTING EARLY-WEEK SYSTEM...ONLY TO BOUNCE RIGHT BACK ON FRIDAY AS THE WARM FRONT LIFTS THROUGH. THE SEE-SAW CONTINUES WITH THE COLD FRONT MOVING THROUGH LATE FRIDAY. HIGHS SATURDAY WILL BE ONLY FROM ABOUT THE MID 60S TO MID 70S. LOWS FROM THE LOWER 50S ADIRONDACKS TO MID 60S VALLEYS WEDNESDAY NIGHT WILL ALSO SEE-SAW...TO LOWS IN THE MID 40S TO UPPER 50S THURSDAY NIGHT...BACK TO THE LOWER 50S TO UPPER 60S RANGE THURSDAY NIGHT... AND BACK DOWN TO THE MID 40S TO NEAR 60 FRIDAY NIGHT. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... SOME LOW TOPPED CONVECTION HAS ALREADY BEGUN TO AFFECT KGFL AND KALB...WITH ISO SHOWERS APPROACHING KPOU THIS AFTERNOON. SHRA WILL CONTINUE THIS AFTERNOON INTO EVENING AS A WEAK COLD FRONT APPROACHES FROM THE NORTHWEST. THIS FRONT WILL MOVE ACROSS THE AREA TODAY AND THIS EVENING AND IS EXPECTED TO STALL OVERNIGHT NEAR THE COAST. HAVE INCLUDED VCSH AS THIS FRONT PROVIDES THE LIFT FOR CONVECTION. AS FOR THUNDERSTORMS...THE BEST CHANCES AT KPOU AND KALB...HAVE INCLUDED CB THIS AFTERNOON. THUNDERSTORM THREAT WILL END WITH LOSS OF HEATING. OVERALL...EXPECT VFR CONDITIONS TODAY AND THIS EVENING. SKIES EXPECTED TO CLEAR OUT TONIGHT AND MVFR FOG MAY DEVELOP AT KPOU LATE AT NIGHT...RECOVERING TO VFR AFTER SUNRISE. WINDS WILL BE SOUTHWEST THIS AFTERNOON AS THE COLD FRONT APPROACHES AND SHIFT WEST TO NORTHWEST WITH ITS PASSAGE THIS EVENING AND OVERNIGHT. WINDS WILL BECOME LIGHT OVERNIGHT...THEN INCREASE OUT OF THE NORTHWEST AT 5-10 KTS SUNDAY MORNING. OUTLOOK... MON AM...VFR...NO SIG WX. MON PM-TUE...VFR-MVFR WITH IFR POSSIBLE WITH A CHC SHRA/TSRA. WED-THU...VFR...NO SIG WX. && .FIRE WEATHER... ...GUSTY WEST-NORTHWEST WINDS EXPECTED ON SUNDAY... IT HAS BEEN WELL OVER ONE WEEK SINCE THE REGION HAS OBSERVED APPRECIABLE RAINFALL. IN THE WAKE OF THE FRONTAL PASSAGE THIS EVENING WITH WIDELY SCATTERED SHOWERS AND THUNDERSTORMS...WEST- NORTHWEST WINDS WILL INCREASE THROUGH THE DAY SUNDAY WITH GUSTS OVER 25 MPH EXPECTED. THIS TOO WILL ASSIST WITH LOW LEVEL DRYING AS MINIMUM RELATIVE HUMIDITIES DROP TO BETWEEN 30 AND 50 PERCENT. SUNDAY NIGHT...A WARM FRONT WILL LIFT NORTH WITH A MINIMAL CHANCE FOR MEASURE PRECIPITATION. MAXIMUM RELATIVE HUMIDITIES WILL RECOVER TO BETWEEN 80 AND 100 PERCENT. THEN CLOUDS ALONG WITH SHOWERS AND THUNDERSTORMS WILL BE ON THE INCREASE MONDAY THROUGH TUESDAY. THIS WILL KEEP LOWER LEVEL MOISTURE RATHER HIGH THROUGH EARLY NEXT WEEK. && .HYDROLOGY... NO HYDRO PROBLEMS ARE ANTICIPATED THE NEXT 5 DAYS. MAIN STEM RIVER FLOWS WILL REMAIN AT BELOW NORMAL TO NORMAL LEVELS. ANY RAIN FROM SHOWERS AND THUNDERSTORMS TODAY...AND MONDAY THROUGH TUESDAY WILL LIKELY SOAK INTO THE GROUND WITH MINIMAL RISES ON RIVERS AND STREAMS EXPECTED.
