The episode as NWS ALY wrote it up.
A strong cold front moved towards the region from the west during the evening of Friday, April 19th. Temperatures were unseasonably warm with highs in the 60s and low 70s across the region. Despite limited low level moisture in place, a line of heavy rain showers with gusty winds was located just ahead and along this approaching frontal boundary. As the line reached eastern New York and western New England, some of these showers strengthened into thunderstorms, with occasional cloud-to-cloud lightning visible. Winds on the leading edge on one of these thunderstorms caused damage to trees in the Berkshires. The showers and thunderstorms ended in the late evening as the front moved through and to the east of the area.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Albany, NY wrote its last area forecast discussion before the first event at Apr 19, 6:12 PM EST, 3 hours 6 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
712 PM EDT FRI APR 19 2013
.SYNOPSIS...
A COLD FRONT WILL CROSS THROUGH THE REGION TONIGHT...BRINGING
WIDESPREAD SHOWERS AND THE THREAT OF THUNDERSTORMS. WITH THE
PASSAGE OF THE COLD FRONT...A COLDER AIRMASS WITH BE USHERED IN ON
BRISK WESTERLY WINDS FOR SATURDAY. HIGH PRESSURE WILL BUILD IN FOR
SUNDAY...WITH SUNSHINE AND LIGHTER WINDS BUT CONTINUED COOL
TEMPERATURES.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
AS OF 630 PM EDT...COLD FRONT WAS ALONG A KMSS...KRME...KITH LINE
WITH SHOWERS AND EMBEDDED ISOLATE THUNDERSTORMS TRACKING NORTH
NORTHEAST ALONG AND BEHIND THE FRONT. THE LEADING EDGE OF THE
SHOWERS WERE MAINLY FROM THE WESTERN ADIRONDACKS AND MOHAWK VALLEY
SOUTHWARD THROUGH THE EASTERN CATSKILLS. THERE IS VERY LITTLE
INSTABILITY IN THE REGION BUT BOUNDARY LAYER WINDS ARE RATHER
STRONG...AS EVIDENCED BY THE STRONG SOUTHERLY WINDS THAT HAVE
MIXED DOWN IN MANY REGIONS WELL AHEAD OF THE FRONT. INDICATING
SOME GUSTS AROUND 40 MPH IN SOME SPOTS JUST DUE TO THE GRADIENT
WIND THROUGH EARLY THIS EVENING. SOME OF THE WINDS BEHIND THE
FRONT FROM THE SOUTHWEST TO NORTHWEST HAVE ACTUALLY BEEN STRONGER
THAN THOSE AHEAD OF THE FRONT.
SOME OF THE NEAR TERM MESOSCALE MODELS SUGGEST A LINE OF ENHANCED
SHOWER ACTIVITY WITH A POSSIBLE RUMBLE OF THUNDER DEVELOPING AS IT
APPROACHES THE CAPITAL DISTRICT...LAKE GEORGE SARATOGA REGION AND
EASTERN CATSKILLS. THEN THE LINE MAINTAINS ITSELF AS IT TRACKS
THROUGH THE REST OF THE REGION. WILL JUST HAVE TO KEEP AN EYE FOR
ANY ISOLATED ENHANCED WIND GUSTS IN CONVECTIVE ELEMENTS BUT THE
CHANCES OF ANY ORGANIZED WIND DAMAGE THREAT IS VERY LOW AT THIS
TIME WITH THE LIMITED INSTABILITY.
THE COLD FRONT SHOULD BE THROUGH OUR REGION AND INTO CENTRAL AND
EASTERN NEW ENGLAND BY SUNRISE...AND BASED ON THE TEMPERATURES AND
SKY COVER BEHIND THE FRONT CURRENTLY...SIDING WITH THE COOLER
TEMPERATURE GUIDANCE FOR LOW TEMPERATURES TONIGHT. LOWS IN THE
40S...WITH SOME MID TO UPPER 30S IN THE SOUTHERN ADIRONDACKS.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
TEMPERATURES SATURDAY WILL HIGHLY DEPEND ON HOW MUCH SUN WE CAN
GET. CURRENTLY QUITE CLOUDY AND COOL BEHIND THE FRONT IN THE GREAT
LAKES AND OH VALLEY. GUIDANCE SUGGESTS SUPPORT FOR LAKE EFFECT
RAIN AND SNOW SHOWERS INTO THE WESTERN MOHAWK VALLEY AND SOUTHERN
ADIRONDACKS. RELATIVELY STRONG COLD ADVECTION AND MOISTURE FROM
THE LAKES ALONG WITH SLOWLY DEPARTING UPPER DYNAMICS COULD KEEP
MANY AREAS IN MORE CLOUDS THAN SUN MUCH OF THE DAY. STRONG WEST TO
NORTHWEST WINDS SHOULD PREVAIL...BUT MAINLY BELOW WIND ADVISORY
CRITERIA. WILL WORD SOME GUSTS AROUND 40 MPH IN SOME AREAS
TOMORROW. BASED ON FORECASTED BOUNDARY LAYER TEMPERATURES AND THE
MIXING POTENTIAL...WENT ON THE COOLER SIDE OF GUIDANCE. BUT
AGAIN...IF SOME SUNSHINE CAN INCREASE DURING THE AFTERNOON...IT
WOULD ADD A FEW DEGREES TO THE HIGH TEMPERATURES LATE. HIGHS IN
THE UPPER 40S TO MID 50S...SOME MID TO UPPER 30S SOUTHERN
ADIRONDACKS.
RELATIVELY STRONG HIGH PRESSURE BUILDS INTO THE REGION SATURDAY
NIGHT THROUGH SUNDAY NIGHT. THERE COULD STILL BE SOME STRONG WEST
TO NORTHWEST BOUNDARY LAYER WINDS SATURDAY NIGHT DIMINISHING
TOWARD SUNRISE SUNDAY MORNING...AND SOME LAKE EFFECT CLOUDINESS IN
WESTERN AREAS. WITH ANY LITTLE BIT OF MIXING WITH ANY PERSISTENT
LIGHT WIND...TEMPERATURES SHOULD BE ON THE WARMER SIDE OF
GUIDANCE...BUT STILL COOL. LOWS IN THE 20S TO AROUND 30...SOME
UPPER TEENS IN THE SOUTHERN ADIRONDACKS.
WINDS SHOULD TREND TO LIGHT ON SUNDAY...BUT WITH QUITE A BIT OF
SUNSHINE IN MANY AREAS. EVEN THOUGH THE BOUNDARY LAYER TEMPERATURES
ARE STILL GOING TO BE COOL...THE STRONG SUN SHOULD HELP
TEMPERATURES TO REACH THE MID TO UPPER 50S...WITH SOME 40S IN THE
SOUTHERN ADIRONDACKS. SUNDAY NIGHT...WITH NEARLY CALM WINDS AND
MOSTLY CLEAR SKY...TEMPERATURES SHOULD FALL TO AROUND THE SAME AS
SATURDAY NIGHT.
ON MONDAY...HIGH PRESSURE BEGINS TO BUILD EAST AND WEAK WARM
ADVECTION BEGINS. LOW LEVEL WINDS SHIFT TO SOUTHEAST...BUT THE DRY
LOW LEVELS SHOULD PREVENT WIDESPREAD CLOUD COVER MUCH OF THE DAY.
HIGHS MONDAY IN THE MID 50S TO AROUND 60.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
UNSETTLED WEATHER IS EXPECTED DURING MUCH OF THE LONG TERM PERIOD
ESPECIALLY WEDNESDAY THROUGH THURSDAY.
MONDAY NIGHT AND TUESDAY...EXPECT CLOUDS TO START INCREASING FROM SOUTHWEST
TO NORTHEAST AS FA BECOMES SANDWICHED BETWEEN LOW PRESSURE IN THE
GREAT LAKES AND LOW PRESSURE MOVING ALONG THE EASTERN SEABOARD EAST
OF CAPE HATTERAS. HAVE PLACED LOW CHANCE POPS IN THE GRIDS ACRS THE
EXTREME SOUTHEAST CORNER OF FA MONDAY NIGHT. EXPECT LOWS GENERALLY
IN THE 30S WITH SOME UPPER 20S ACROSS THE WESTERN ADIRONDACKS AND
SOUTHERN GREEN MOUNTAINS. HIGHS ON TUESDAY ARE EXPECTED TO BE IN THE
UPPER 40S TO UPPER 50S.
TUESDAY NIGHT THROUGH WEDNESDAY NIGHT...THE LOW PRESSURE SYSTEM
MOVING THROUGH THE UPPER GREAT LAKES WILL START TO SWING A COLD
FRONT INTO THE EASTERN GREAT LAKES BY WEDNESDAY MORNING AS THE
COASTAL LOW LIFTS SLOWLY NORTHWARD TO A POSITION EAST OF CAPE COD BY
WEDNESDAY MORNING. AS THESE TWO SYSTEMS START TO IMPACT THE FA HAVE
PLACED INCREASING POPS ACRS THE REGION PARTICULARLY WEDNESDAY AND
WEDNESDAY NIGHT WITH THE HIGHEST POPS WEDNESDAY NIGHT AS THE COLD
FRONT MOVES ACRS THE FA AND BECOMES NEARLY STATIONARY JUST TO OUR
EAST WITH ANOTHER WAVE OF LOW PRESSURE EXPECTED TO LIFT NORTHWARD
ALONG THE FRONTAL BOUNDARY. LOWS TUESDAY NIGHT ARE EXPECTED TO
GENERALLY BE IN THE MID 30S TO LOWER 40S WITH HIGHS ON WEDNESDAY IN
THE 50S TO MID 60S AND LOWS WEDNESDAY NIGHT IN THE MID 30S TO MID
40S.
THURSDAY...THE FORECAST IS RATHER UNCERTAIN AS IT WILL HINGE ON HOW
CLOSE THE FRONTAL BOUNDARY REMAINS TO OUR FA AND WHERE THE LOW
PRESSURE SYSTEM TRACKS ALONG THE FRONTAL BOUNDARY. DUE TO THE
UNCERTAINTY WILL LEAVE CHANCE POPS IN THE GRIDS FOR NOW WITH HIGHS
GENERALLY IN THE UPPER 40S TO UPPER 50S.
OVERALL EXPECT ABOVE NORMAL PRECIPITATION AND BELOW NORMAL TEMPS
DURING THE LONG TERM PERIOD.
&&
.AVIATION /23Z FRIDAY THROUGH WEDNESDAY/...
A COLD FRONT WILL MOVE ACROSS THE LOCAL AREA THIS EVENING
ACCOMPANIED BY SHOWERS. THERE IS THE THREAT FOR A LOW-TOPPED
CONVECTIVE BAND TO DEVELOP IF THE AIRMASS CAN BECOME DESTABILIZED
ENOUGH. WILL HAVE STRONG VERTICAL SHEAR AND LARGE SCALE ASCENT
ACROSS REGION. HAVE A PERIOD OF SHOWERS IN TAFS WITH MVFR
CONDITIONS AS COLD FRONT MOVES THROUGH. DO NOT HAVE MENTION OF
THUNDERSTORM IN TAFS BUT DO HAVE A TEMPO FOR HIGHER WIND GUSTS AS
CONVECTION PULLS STRONGER WINDS DOWN ALONG WITH IFR CONDITIONS FOR
THE HEAVIER SHOWERS THROUGH AROUND MIDNIGHT.
THE LOW LEVEL JET INCREASES EARLY THIS EVENING AHEAD OF THE COLD
FRONT ESPECIALLY ACROSS SOUTHEAST NY AND NEW ENGLAND. HAVE INCLUDE
LOW LEVEL WIND SHEAR IN KPOU TAF AS IT GETS INTO THE STRONG LOW
LEVEL JET. THIS THREAT WILL END WITH THE PASSAGE OF THE COLD
FRONT.
THE COLD FRONT FEATURES A STRONG THERMAL GRADIENT AND TEMPERATURES
ARE DROPPING OFF QUICKLY WITH ITS PASSAGE AS WINDS SHIFT TO THE WEST
USHERING IN A COLDER...MORE SEASONABLE AIRMASS. WINDS WILL QUIET
DOWN LATE TONIGHT THEN PICK UP OUT OF THE WEST AND BECOME BRISK
AND GUSTY AFTER SUNRISE WITH A TIGHT PRESSURE GRADIENT ACROSS
REGION.
OUTLOOK...
SAT NIGHT-MON...VFR. NO SIG WX.
MON NIGHT-TUE...VFR/MVFR. SLGT CHC -SHRA.
WED...VFR-MVFR. CHC -SHRA.
&&
.FIRE WEATHER...
GUSTY SOUTHERLY WINDS THE REST OF THE AFTERNOON UP TO AROUND
40 MPH...
GUSTY WEST TO NORTHWEST WINDS UP TO AROUND 40 MPH ARE EXPECTED
TOMORROW...
A COLD FRONT WILL CROSS THROUGH THE REGION TONIGHT...BRINGING
WIDESPREAD SHOWERS AND THE THREAT OF THUNDERSTORMS. WITH THE
PASSAGE OF THE COLD FRONT...A COLDER AIRMASS WITH BE USHERED IN ON
BRISK WESTERLY WINDS FOR SATURDAY. HIGH PRESSURE WILL BUILD IN FOR
SUNDAY...WITH SUNSHINE AND LIGHTER WINDS BUT CONTINUED COOL
TEMPERATURES.
WE CAN EXPECT A QUARTER INCH OF RAIN OR MORE WITH THE COLD FRONT
TONIGHT. SCATTERED THUNDERSTORMS ARE POSSIBLE THIS EVENING.
RELATIVE HUMIDITIES SHOULD BE 80 TO 100 PERCENT TONIGHT...DROPPING
TO 30 TO 45 PERCENT TOMORROW. RELATIVE HUMIDITIES SHOULD RISE TO
70 TO 90 PERCENT TOMORROW NIGHT AND DROP TO AROUND 25 PERCENT
SUNDAY.
THE WIND WILL TURN TO THE NORTHWEST OVERNIGHT. THIS WIND WILL
USHER MUCH COOLER AIR FOR SATURDAY. THE WIND WILL BE 15-25 MPH
WITH GUSTS OVER 35 MPH. SUNDAY LOOKS MOSTLY SUNNY AND DRY WITH
LIGHTER WINDS...GENERALLY VARIABLE AT 15 MPH OR LESS.
THE NEXT CHANCE FOR SIGNIFICANT PRECIPITATION FOLLOWING
TONIGHT...WILL BE MONDAY NIGHT INTO WEDNESDAY.
&&
.HYDROLOGY...
NO WIDESPREAD HYDRO PROBLEMS ARE LIKELY DURING THE NEXT FIVE DAYS.
A COLD FRONT WILL BRING A ROUND OF SHOWERS AND POSSIBLE
THUNDERSTORM LATER INTO THE EVENING WITH RAINFALL AMOUNTS STILL
LOOKING TO BE BETWEEN A HALF INCH TO AN INCH ACROSS OUR ENTIRE
REGION.
THE COMBINATION OF THIS RAINFALL AND THE SNOW MELT WILL LIKELY CAUSE
SIGNIFICANT WITHIN BANKS OF RIVERS TO OUR NORTH...INCLUDING THE
SCHROON. HOWEVER...NO FLOODING IS LIKELY ASSUMING THESE RAINFALL
AMOUNTS ARE CORRECT.
THE RAIN COULD COME DOWN BRIEFLY HEAVILY AND PRODUCE SOME PONDING OF
WATER IN AREAS OF POOR DRAINAGE THIS EVENING.
THE RAIN WILL TAPER TO LEFTOVER LIGHTER SHOWERS TOWARD SATURDAY WITH
SOME OF THESE IN THE FORM OF SNOW SHOWERS IN THE MOUNTAINS WITH
LITTLE IF ANY ACCUMULATION.
OTHERWISE...IT WILL BE MAINLY DRY SATURDAY THROUGH MONDAY. COOLER
TEMPERATURES IN THE MOUNTAINS WILL SLOW THE AMOUNT SNOW MELT AND
RESULTANT RUNOFF.
THE NEXT CHANCE OF PRECIPITATION WILL BE MONDAY NIGHT THROUGH
WEDNESDAY. IT MIGHT BE COLD ENOUGH FOR SOME OF THE PRECIPITATION
TO FALL AS SNOW IN THE MOUNTAINS.
