NWS Albany, NY wrote its last area forecast discussion before the first event at Apr 27, 12:56 AM EST, 4 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
156 AM EDT WED APR 27 2011
.SYNOPSIS...
A WARM FRONT WILL CONTINUE TO MOVE MOVE NORTHWARD BEYOND THE
SOUTHERN ADIRONDACKS...LAKE GEORGE SARATOGA REGION AND SOUTHERN
VERMONT OVERNIGHT...USHERING IN A WARM AND HUMID AIRMASS. A COLD
FRONT WILL MOVE ACROSS THE REGION BUT NOT UNTIL THURSDAY. OUR
WEATHER WILL BE UNSETTLED WITH THE CHANCES FOR SHOWERS AND
THUNDERSTORMS WITH THE BEST CHANCES EXPECTED WITH THE PASSAGE OF
THE COLD FRONT.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
AS OF MIDNIGHT...WITH ON GOING CONVECTION...RUNOFF FROM EARLIER
RAINFALL AND SNOW MELT OCCURRING AND RISING STREAMS AND RIVERS
EXTENDED FLOOD WATCH AN ADDITIONAL 12 HOURS UNTIL NOON WEDNESDAY.
LINE OF CONVECTION MOVING ACROSS EASTERN PORTION OF FORECAST AREA
EARLY THIS MORNING. MINOR UPDATE TO ADJUST ITS TIMING AND TO
GRADUALLY REMOVE MENTION OF THUNDER THROUGH THE EARLY MORNING
HOURS. MINOR ADJUSTMENTS TO TEMPERATURES...DEW POINTS...WIND AND
SKY OVER GRIDS.
AS OF 1000 PM...WIDESPREAD TO NUMEROUS SHOWERS MOVING INTO THE
SOUTHWEST PART OF THE FORECAST AREA...SO HAVE RAISED POPS
CONSIDERABLY THERE UNTIL A LITTLE AFTER MIDNIGHT. ISOLATED SEVERE
THREAT CONTINUES AS STRONG GUST FRONT SEEN ON KENX RADAR MOVING
SCHOHARIE COUNTY AND EASTERN CATSKILLS. THIS GUST FRONT MUCH
DIMINISHED FROM BEFORE WHEN IT WAS OVER BGM/S AREA...BUT HAVE ISSUED
ONE SVR WARNING FOR SCHOHARIE COUNTY AND SEE WHAT HAPPENS AS IT
MOVES THROUGH.
****PREVIOUS DISCUSSION****
AS OF 730 PM EDT...INITIAL CLUSTER OF SHOWERS/TSTMS IS MOVING NORTH
OF THE REGION. STILL MAY IMPACT EXTREME NORTHERN HAMILTON/WARREN COS
OVER THE NEXT HOUR...BEFORE LIFTING NORTH.
OTHERWISE...THERE SHOULD BE A 1-3 HOUR PERIOD WITHOUT ANY
THUNDERSTORMS ACROSS THE REGION...LONGEST ACROSS THE HUDSON RIVER
VALLEY REGION AND POINTS EAST...WHICH MAY REMAIN DRY UNTIL LATE THIS
EVENING...AND POSSIBLY UNTIL MIDNIGHT ACROSS WESTERN NEW ENGLAND.
THE CONVECTIVE LINE FROM THE WEST SHOULD REACH THE EXTREME WESTERN
DACKS BETWEEN 8-9 PM...AND THE WESTERN MOHAWK VALLEY BETWEEN 9-10
PM. THIS LINE/BAND SHOULD CONTINUE MOVING E BETWEEN 10 PM-MIDNIGHT
INTO THE MOHAWK/SCHOHARIE VALLEYS...AND THEN INTO THE LAKE
GEORGE/SARATOGA REGIONS...AND ACROSS PORTIONS OF THE CAPITAL
REGION. TSTM INTENSITY HAS BEEN WEAKENING BASED ON LATEST RADAR
TRENDS...BUT WILL NEED TO REMAIN VIGILANT DUE TO LINGERING
INSTABILITY/WARM SFC TEMPS WITHIN THE HUDSON RIVER VALLEY REGION.
THE OTHER ASPECT TO THE FORECAST TO WATCH THIS EVENING WILL BE THE
APPROACH OF ANOTHER BOUNDARY FROM THE EAST...CURRENTLY MOVING WEST
ACROSS EAST CENTRAL MA AND SOUTHERN NH. THERE IS A POSSIBILITY
THAT THIS BOUNDARY MAY MOVE FURTHER WESTWARD OVERNIGHT...INITIALLY
PROVIDING THE FOCUS FOR ADDITIONAL CONVECTION...AND ALSO ALLOWING
MIN TEMPS TO FALL MORE RAPIDLY ACROSS EASTERN AREAS THAN
CURRENTLY INDICATED. WILL MONITOR TRENDS CLOSELY OVER THE NEXT FEW
HOURS.
PREVIOUS DISCUSSION FOLLOWS...
SEVERE THUNDERSTORM WATCH CONTINUES UNTIL 9 PM. WARM FRONT STILL
ACROSS NORTHERN NY AND SOUTHERN VT PROVIDING LOW LEVEL FOCUS FOR
ENHANCED CONVERGENCE SUPPORTING STRONG TO SEVERE CONVECTION. SOME
ROTATION SEEN IN STORMS DUE TO LOW LEVEL SHEAR ALONG AND JUST
NORTH OF THE WARM FRONT. OTHER LINEAR CONVECTIVE FEATURES SEEN IN
NY/PA AND DOWN THE APPALACHIANS LIKELY SUPPORTED BY STRENGTHENING
SOUTH TO SOUTHWEST BOUNDARY LAYER JET ENERGY AND MOISTURE
ADVECTION. A VIL OF AROUND 64 RESULTED IN PING PONG TO GOLF BALL
HAIL...SO VILS IN THE 50S SEEM TO SUPPORT QUARTER HAIL.
THE HRRR SUGGESTS CONVECTION WILL CONTINUE TO ORGANIZE INTO THIS
EVENING...AND SHOULD AFFECT PARTS OF THE CATSKILLS...SCHOHARIE
VALLEY...WESTERN MOHAWK VALLEY...SOUTHERN ADIRONDACKS...LAKE
GEORGE SARATOGA REGION...AND CAPITAL DISTRICT...WITH MORE
SCATTERED ACTIVITY IN SOUTHERN VT...WESTERN MA...TACONICS...MID
HUDSON VALLEY AND NW CT. SOME SUGGESTION BY GUIDANCE THAT AS
SURFACE HIGH IN CANADA BUILDS EAST...THE WARM FRONT MAY STRUGGLE
TO PUSH NORTH AND EAST...AND THE CONVECTION COULD NUDGE THE WARM
FRONT BACK SOUTH AGAIN TEMPORARILY INTO THE MOHAWK VALLEY AND
CAPITAL DISTRICT. THIS MIGHT RESULT IN MORE CLOUD COVER AND
SLIGHTLY COOLER LOW TEMPERATURES...AND MORE FOG TONIGHT...BUT FOR
NOW HOLDING POSITION OF WARM FRONT AS IS THIS EVENING...THEN
SLOWLY PUSHING NORTH LATER TONIGHT AND TOMORROW MORNING.
SO...LIKELY SHOWERS AND STORMS IN CENTRAL AND NORTHERN
AREAS...SCATTERED ACTIVITY SOUTH AND EAST. LOWS IN THE MID TO
UPPER 50S ALONG AND NORTH OF THE WARM FRONT...AND LOWER 60S SOUTH
OF THE WARM FRONT. WILL KEEP AN EYE ON TRENDS TO SEE IF LOW
CLOUDS...FOG AND COOLER TEMPERATURES DO DRAIN SOUTH AGAIN THIS
EVENING AND OVERNIGHT.
CONVECTIVE RAINFALL IN SOUTHERN ADIRONDACKS AND WESTERN MOHAWK
VALLEY SUPPORTS CONTINUATION OF THE FLOOD WATCH...ESPECIALLY SINCE
SOME POINTS ARE IN FLOOD NOW.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/...
ANY LINGERING SHOWER ACTIVITY LATE TONIGHT INTO TOMORROW MORNING
SHOULD BECOME ISOLATED...AND DAYTIME MIXING SHOULD HELP ERODE ANY
LOW CLOUDS AND/OR FOG IN THE PROXIMITY OF THE WARM FRONT...IF IT
HAS NOT MOVED NORTH AND EAST OUT OF OUR REGION BY MORNING.
BOUNDARY LAYER WINDS BACK TO MORE SOUTH TO SOUTH SOUTHWEST.
SO...WITH INCREASING DEEP MOISTURE...SKY SHOULD BE MORE PARTLY
CLOUDY...BUT STILL ENOUGH SUN TO BOOST TEMPERATURES INTO THE 70S
TO AROUND 80 IN MOST AREAS. IF MORE SUN...THEN SIMILAR TO TODAY
WITH TEMPERATURES WAY ABOVE GUIDANCE VALUES...TOO EARLY TO TELL
FOR SURE AT THIS TIME. NO ORGANIZED LOW LEVEL FOCUS FOR
CONVECTIVE ACTIVITY TOMORROW AFTERNOON...BUT INCREASING LOW LEVEL
JET ENERGY AND GENERAL INSTABILITY COULD SUPPORT SOME CONVECTION
IN HIGHER TERRAIN THAT COULD TRACK ACROSS SOME OF THE REGION.
SO...SCATTERED SHOWER AND THUNDERSTORM ACTIVITY FOR TOMORROW
AFTERNOON.
BETTER UPPER DYNAMICS AND LOW LEVEL FORCING WILL TRACK INTO OUR
REGION TOMORROW NIGHT AND THURSDAY. A BAND OR ORGANIZED LINE OF
THUNDERSTORMS...SOME STRONG...SHOULD FORM AND TRACK THROUGH THE
REGION. THERE SHOULD BE SOME BREAKS IN THE CLOUDS OUTSIDE OF THE
BAND OF SHOWERS AND STORMS...ALLOWING TEMPERATURES TO RISE INTO
THE 70S IN MANY AREAS. THE TIMING OF THE FRONTAL PASSAGE A BIT IN
QUESTION...BUT WITH THE UPPER DYNAMICS QUITE SLOW TO
EXIT...FAVORING SLOWER FRONTAL PASSAGE. IT ALSO SUGGESTS THAT SOME
LINGERING CLOUDS AND SHOWERS COULD OCCUR INTO THURSDAY NIGHT.
SOME SLOW CLEARING AND COOLING IS EXPECTED THURSDAY NIGHT AND
FRIDAY...WITH LOWS THURSDAY NIGHT IN THE 40S TO AROUND 50...MAYBE
SOME UPPER 30S SOUTHERN ADIRONDACKS. HIGHS FRIDAY IN THE LOWER TO
MID 60S...SOME 50S IN HIGHER TERRAIN.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
WITH AN UPPER LEVEL TROUGH REMAINING OVER THE REGION IN THE WAKE OF
A SFC COLD FRONTAL BOUNDARY...SOME CYCLONIC FLOW SHOWERS ARE
POSSIBLE ON FRIDAY NIGHT...MAINLY FOR NORTHERN AND WESTERN
AREAS...AND ESPECIALLY FOR TYPICALLY UPSLOPE FAVORED AREAS. P-TYPE
WILL GENERALLY BE -SHRA...BUT SOME -SHSN MAY MIX IN AT TIMES LATER
DURING THE NIGHT FOR THE HIGHEST ELEVATIONS.
BOTH HIGH PRESSURE AT THE SFC AND RIDGING ALOFT WILL BUILD INTO THE
AREA FOR SAT INTO SAT NIGHT...ALLOWING FOR DRY CONDITIONS AND NEAR
SEASONABLE TEMPS. HOWEVER...THE QUIET WEATHER WILL BE SHORT
LIVED...AS YET ANOTHER FRONTAL SYSTEM APPROACHES THE AREA FOR LATER
IN THE WEEKEND.
THE MODELS CONTINUE TO DISAGREE WITH THE EXACT TIMING OF THIS
SYSTEM. BOTH THE 00 UTC AND 12 UTC RUNS OF THE ECMWF HAVE BEEN
PERSISTENT IN DELAYING THIS SYSTEM...SO SUNDAY COULD WIND UP BEING A
DRY DAY IF THIS SCENARIO IS CORRECT...AS THE BEST ISENTROPIC LIFT
ALONG THE WARM FRONT REMAINS TO THE WEST OF THE AREA. THE 12 UTC
GGEM ALSO AGREES WITH THIS SCENARIO. HOWEVER...THE 12 UTC GFS
ALLOWS FOR -SHRA TO SPREAD ACROSS THE AREA AS EARLY AS SUNDAY
MORNING...ESP FOR WESTERN AREAS. FOR NOW...WILL GO WITH LOW CHC POPS
FOR CENTRAL AND WESTERN AREAS...AND SLIGHT CHC POPS FOR EASTERN
AREAS /WESTERN NEW ENGLAND/ BECAUSE OF THIS UNCERTAINTY. WITH THE
WARMER TEMPS MOVING IN ALOFT...WILL ALLOW FOR MAX TEMPS A BIT WARMER
ON SUNDAY THAN SATURDAY...WITH UPPER 60S TO LOW 70S IN VALLEY
AREAS...ALTHOUGH THIS WILL ULTIMATELY DEPEND ON HOW MUCH SUNSHINE
OCCURS.
WITH THE FRONT NEARBY...WILL CONTINUE THE CHC OF SHOWERS FOR SUNDAY
NIGHT THROUGH TUESDAY. THE GFS CLEARS THE FRONT THROUGH THE AREA BY
LATE MONDAY NIGHT...WHILE THE ECMWF LINGERS THE FRONT THROUGH
TUESDAY. AHEAD OF THE BOUNDARY...WILL CONTINUE TO KEEP TEMPS NEAR OR
SLIGHTLY ABOVE NORMAL FOR MONDAY...AND THEN COOL TEMPS OFF BY
SEVERAL DEGREES FOR TUESDAY...ALTHOUGH THIS WILL DEPEND ON JUST HOW
QUICKLY THE FRONT MOVES THROUGH...AND HOW MUCH CLOUD COVER REMAINS
OVER THE AREA AS WELL.
&&
.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
AS OF 130 AM...0530Z...A LINE OF SHOWERS AND EMBEDDED THUNDER
STORMS HAD PASSED KALB AND KGFL AND WAS MOVING ACROSS SOUTHERN
VERMONT AND WESTERN MASSACHUSETTS TO THE CONNECTICUT RIVER. TO
THE SOUTH...THEY WERE STILL TO THE WEST OF KPOU...AND WILL
AFFECT KPOU BETWEEN 06Z AND 07Z. WE HAVE TEMPO MVFR WITH WIND
GUSTS TO 20 KTS DURING THAT HOUR. CONDITIONS WILL BECOME MVFR
BETWEEN 06Z AND 08Z AS SOME COOLING TAKES PLACE AND LIGHT FOG
OR MIST REDUCES VISIBLITY...AND CLOUD BASES ARE EXPECTED TO
LOWER TO AROUND 1500 FT BY 10Z. LOW LEVEL MOISTURE WILL RESULT
IN LOTS OF LOW CLOUDS THIS MORNING...WITH MVFR CIGS...WHICH
WILL IMPROVE TO VFR BY AROUND NOON. HOWEVER SCATTERED SHOWERS
AND THUNDERSTORMS WILL POP UP IN THE UNSTABLE AIR DURING THE
AFTERNOON. THIS EVENING...AGAIN LOW CLOUDS AND FOG OR MIST WILL
CAUSE CONDITIONS TO DETERIORATE TO MVFR.
WINDS DURING THE PREDAWN HOURS WILL BE LIGHT AND VARIABLE...AND
DURING THE DAY TODAY THEY WILL BE MOSTLY FROM THE SOUTH 10 TO
12 KNOTS WITH GUSTS TO 18 KNOTS DURING THE AFTERNOON.
OUTLOOK...
THIS EVENING...MVFR...CHC TSRA/SHRA.
TONIGHT...MVFR...BECMG IFR IN LOW STRATUS/FOG/MIST
THURSDAY...MVFR/IFR...-SHRA/-TSRA. CHC SVR TSTMS.
THU NIGHT-FRI...VFR/MVFR...CHC -SHRAS.

.FIRE WEATHER...
A WARM FRONT WILL MOVE FINISH MOVING NORTHWARD ACROSS THE REGION
THIS EVENING USHERING IN A WARM AND HUMID AIRMASS. A COLD FRONT
WILL MOVE ACROSS THE REGION BUT NOT UNTIL THURSDAY. OUR WEATHER
WILL BE UNSETTLED WITH THE CHANCES FOR SHOWERS AND THUNDERSTORMS
WITH THE BEST CHANCES EXPECTED WITH THE PASSAGE OF THE COLD FRONT.
WITH MOST AREAS EXPECTED TO RECEIVE RAINFALL PERIODICALLY THROUGH
THURSDAY...AND NO WIDESPREAD WINDS OF 25 MPH OR MORE EXPECTED...
MOST FUELS SHOULD REMAIN MOIST ENOUGH TO MINIMIZE FIRE CONCERNS AT
LEAST THROUGH THURSDAY.

GJMThe Burlington radar (KCXX), 116 km away, was scanning. The volume nearest the first event began at 06:01 UTC.
1 flash flood, 1 flood. Local standard time, as filed.
Washouts occurred on 13th Lake, Parrish and Beach Roads in Johnsburg due to very heavy rainfall from thunderstorms.
The Hudson River at North Creek rapidly rose due to runoff from the very heavy rainfall from thunderstorms. This resulted in up to 4 feet of water flowing over the low points of Old River Road cutting off access to a dozen households.
