Severe Thunderstorm Warning 119, NWS Albany, NY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
141 PM EDT MON JUL 27 2009

.SYNOPSIS...
AN UPPER LEVEL TROUGH WILL REMAIN ANCHORED ACROSS THE GREAT LAKES
MUCH OF THIS WEEK. A SOUTHWEST FLOW ON THE EASTERN SIDE OF THIS
TROUGH WILL KEEP WARM AND HUMID CONDITIONS ACROSS THE REGION...ALONG
WITH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS. THE BEST
CHANCE FOR SHOWERS AND THUNDERSTORMS WILL BE LATE WEDNESDAY INTO
THURSDAY AS A COLD FRONT MOVES ACROSS FROM THE WEST.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AS OF 1255 PM...SOME STRONG STORMS HAVE DEVELOPED EARLY THIS
AFTERNOON...MAINLY NEAR THE CAPITAL/SARATOGA REGIONS AS WELL AS
SOUTHERN VERMONT. IT APPEARS SBCAPE VALUES EXCEEDING 2000 J/KG ARE
BEING REALIZED DESPITE A MID LEVEL CAP THAT WAS IN PLACE THIS
MORNING. STILL NOT SEEING ROBUST DEVELOPMENT JUST YET...BUT THERE IS
ENOUGH CONCERN FOR SPC TO PLACE MUCH OF THE AREA /EXCEPT FOR
HERKIMER CO/ IN A SLIGHT RISK FOR SEVERE STORMS. WILL UPDATE THE HWO
ACCORDINGLY TO MENTION THE POTENTIAL FOR DAMAGING WIND GUSTS WITH
SOME THUNDERSTORMS. WIND APPEARS TO BE THE MAIN THREAT WITH FAIRLY
STRONG DEEP LAYER WIND FIELD IN PLACE...ALTHOUGH HAIL WILL ALSO BE
POSSIBLE ESPECIALLY IN ANY TALLER UPDRAFTS THAT CAN FORM.

PREVIOUS NEAR TERM DISCUSSION...

AS OF 1131 AM...MONITORING POTENTIAL FOR STRONG CONVECTION
DEVELOPING. A NORTH-SOUTH ORIENTED SURFACE TROF /WIND SHIFT AND
DEWPOINT BOUNDARY/ IS CURRENTLY MOVING THROUGH THE AREA...AND
APPEARS TO MOVING THROUGH THE MOHAWK VALLEY. CONVECTIVE CELLS HAVE
JUST STARTED TO DEVELOP WITHIN THE LAST HALF HOUR IN AND AROUND THE
CAPITAL REGION. FROM THE HUDSON VALLEY EASTWARD...DEWPOINTS ARE IN
THE MID TO UPPER 60S...BUT DROP TO NEAR 60 ACROSS CENTRAL NEW YORK
BEHIND THE TROF. ALSO...LOW LEVEL CONVERGENCE BOUNDARY SETTING UP
WITH WESTERLY WINDS ACROSS CENTRAL NY...WITH SOUTH TO SOUTHEAST
WINDS IN THE HUDSON VALLEY EASTWARD. VIS SATELLITE IMAGERY SHOWS A
LOT OF AGITATED CU ACROSS MUCH OF UPSTATE NY AND VERMONT. CONVECTIVE
PARAMETERS ARE A BIT QUESTIONABLE IN TERMS OF GENERATING SEVERE
STORMS. 12Z ALB SOUNDING REVEALED A DECENT MID LEVEL CAP AROUND
12-13 KFT...WHICH SHOULD LIMIT TALL UPDRAFTS. HOWEVER...THERE IS A
SIGNIFICANT MAGNITUDE OF DEEP LAYER SHEAR WITH 0-6 KM VALUES OF
35-40 KT. SO IF STORMS CAN BREAK THROUGH THE CAP...THEY WILL BECOME
ORGANIZED RATHER QUICKLY. SINCE THE SEVERE THREAT IS STILL IN
QUESTION...BUT SOME STRONGER STORMS ARE POSSIBLE...WILL MENTION
ENHANCED WORDING OF GUSTY WINDS AND SMALL HAIL FOR THE AFTERNOON
MAINLY FROM THE MOHAWK VALLEY AND SOUTHEAST ADIRONDACKS EASTWARD.
STILL EXPECTING COVERAGE TO BE SCATTERED...WITH GENERALLY 40-50 POPS
ACROSS THE AREA THIS AFTERNOON INTO EARLY EVENING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
TONIGHT...OTHER THAN SOME LINGERING ISOLATED/SCATTERED
SHOWERS/STORMS...MAINLY ACROSS E AREAS...IT APPEARS THAT SKIES
SHOULD BECOME MAINLY CLEAR. THIS...IN COMBINATION WITH LIGHT WINDS
AND MOIST GROUND CONDITIONS SHOULD ALLOW AT LEAST PATCHY FOG TO
DEVELOP...WITH SOME POTENTIAL FOR AREAS OF DENSE VALLEY FOG.
OTHERWISE...EXPECT MIN TEMPS TO FALL INTO THE LOWER/MID 60S ACROSS
MOST VALLEY AREAS...WARMEST TO THE SOUTH...WITH SOME MID/UPPER 50S
EXPECTED ACROSS HIGHER ELEVATIONS WITHIN THE NORTH COUNTRY AND
WESTERN NEW ENGLAND.

TUE/TUE NT...AT THIS POINT...THIS PERIOD APPEARS TO HAVE THE LEAST
THREAT FOR CONVECTION...AS WEAK MID LEVEL RIDGING BUILDS IN AHEAD OF
AMPLIFYING MID/UPPER LEVEL TROUGH ACROSS THE PLAINS. WE WILL RETAIN
SLIGHT CHC POPS FOR AN ISOLATED AFTERNOON SHOWER/TSTM...BUT IT
APPEARS THAT THIS THREAT MIGHT BE GREATEST FOR HIGHER TERRAIN...ESP
ACROSS SOUTHERN VT...POSSIBLY LEAVING VALLEY REGIONS UNSCATHED.
GIVEN EXPECTATION FOR MORE SUNSHINE THAN MONDAY...WILL INDICATED MAX
TEMPS A DEGREE OR TWO WARMER THAN MONDAY/S MAXES...GENERALLY IN THE
MID 80S IN THE VALLEYS...AND 75-80 ACROSS THE HIGHER ELEVATIONS.
FORECAST MAXES STILL RUN A BIT COOLER THAN THE MAV/MET MOS
BLEND...OWING TO RECENT TRENDS. FOR TUE NT...EXPECT MAINLY DRY
CONDITIONS...ALTHOUGH THE THREAT FOR ISOLATED SHOWERS WILL INCREASE
TOWARD WED MORNING...ESP ACROSS NW AREAS. A DEVELOPING SOUTH WIND
SHOULD ALLOW FOR WARMER MINS THAN MON NT/TUE AM...WITH MAINLY 60S IN
THE VALLEYS...AND UPPER 50S FOR HIGHER ELEVATIONS/NORTH COUNTRY.

WED...COLD FRONT WILL GRADUALLY APPROACH FROM THE WEST. MODELS
DEPICT DEEP MOISTURE INCREASING ACROSS THE REGION DURING THE
DAY...WITH PWAT/S APPROACHING 1.75 INCHES. WE EXPECT SCATTERED TO
NUMEROUS SHOWERS/STORMS TO DEVELOP BY AFTERNOON...WITH GREATEST
AREAL COVERAGE EXPECTED ACROSS NW/W AREAS. WED SHOULD ALSO BE QUITE
WARM...WITH MAX TEMPS REACHING THE MID...TO PERHAPS UPPER 80S WITHIN
VALLEY LOCALES...DEPENDENT ON TIMING ARRIVAL OF CLOUDS/SHOWERS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
GLOBAL MODELS ARE IN FAIR AGREEMENT WITH NEXT SHORT WAVE ROUNDING
THE BASE OF THE TROUGH AND ASSOCIATED UPPER LOW ACROSS SOUTH-CENTRAL
CANADA BRINGING AN INFLUX OF MOISTURE NORTHEAST INTO THE REGION
WEDNESDAY NIGHT.  HIGH PWATS REMAIN IN PLACE WHICH WILL BRING THE
CONTINUED THREAT OF HEAVY RAINFALL FROM THUNDERSTORMS.

IT SEEMS IN THE WAKE OF THIS SYSTEM THAT WEAK SUBSIDENCE OCCURS AND
WILL FLOW THIS IDEA FOR A DRY THURSDAY.  BUT ANOTHER SHOWER ACROSS
THE HILLTOPS CAN NOT BE RULED OUT WITH ABUNDANCE OF LOW LEVEL
MOISTURE ALREADY IN PLACE.  SOMEWHAT DRIER CONDITIONS ARE EXPECTED
SATURDAY /THE FIRST OF AUGUST/ BEFORE ANOTHER SHORT WAVES DIVES
SOUTHEAST AROUND THE PERIPHERY OF THE UPPER LOW FOR AN ADDITIONAL
SHOWERS AND THUNDERSTORMS SATURDAY NIGHT INTO SUNDAY AIRFRAME.

TEMPERATURES THROUGH THE PERIOD WILL AVERAGE NEAR TO SLIGHTLY ABOVE
NORMAL WITH RECITATION AT NORMAL LEVELS OR HIGHER.

&&

.AVIATION /18Z MONDAY THROUGH FRIDAY/...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP
THROUGHOUT THIS AFTERNOON INTO EARLY EVENING. CURRENT RADAR
INDICATES THUNDERSTORMS FORMING IN THE HUDSON VALLEY AND MOVING
NORTHEAST AWAY FROM KALB/KGFL. WILL MENTION CB QUALIFIER AT
KGFL/KALB SINCE A FEW CONVECTIVE CELLS ARE IN THE AREA BUT NOT
EXPECTED TO REACH THE TAF SITES. FARTHER TO THE SOUTH...STORMS ARE
FORMING IN NORTHEAST PA AND MOVING NORTHEAST TOWARD KPOU. WILL
MENTION TEMPO FOR TSRA UNTIL 20Z AT KPOU AND ASSOC BRIEF IFR/MVFR
CONDITIONS. SHOWERS AND THUNDERSTORMS SHOULD BEGIN TO DISSIPATE BY
EARLY EVENING AS DAYTIME HEATING IS LOST AND DRIER AIR MOVES IN FROM
THE WEST.

OVERNIGHT...MAIN ISSUE WILL BE RADIATION FOG FORMING AROUND 03Z-05Z
AT ALL TERMINALS. KGFL HAS THE BEST CHANCE OF IFR CONDITIONS...WHILE
AT LEAST MVFR CONDITIONS POSSIBLE AT KALB/KPOU DUE TO REDUCED VSBYS
BY 07Z-08Z. BY 12Z-13Z CONDITIONS SHOULD IMPROVE AT ALL TERMINALS TO
VFR.

WINDS WILL INITIALLY BE SOUTH-SOUTHWEST THROUGH MID-LATE AFTERNOON
AROUND 10 KT...THEN SHIFT TO THE WEST-SOUTHWEST BEHIND THE PASSAGE
OF A SURFACE TROUGH AND BECOME GUSTY AT KALB WHERE SOME CHANNELING
DOWN THE MOHAWK VALLEY WILL BRIEFLY OCCUR. WINDS WILL SUBSIDE AFTER
DARK...WITH NEAR CALM WINDS EXPECTED OVERNIGHT INTO EARLY TUE
MORNING.

OUTLOOK...
TUES-FRI...MAINLY VFR...WITH CHANCE MVFR/IFR ASSOC WITH MAINLY
AFTERNOON AND EVENING -SHRA/TSRA. EARLY MORNING FOG/LOW STRATUS
POSSIBLE EACH DAY AS WELL.

&&

.FIRE WEATHER...
AN UPPER LEVEL TROUGH WILL REMAIN ANCHORED ACROSS THE GREAT LAKES
MUCH OF THIS WEEK. A SOUTHWEST FLOW ON THE EASTERN SIDE OF THIS
TROUGH WILL KEEP WARM AND HUMID CONDITIONS ACROSS THE REGION...ALONG
WITH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS. THE BEST
CHANCE FOR SHOWERS AND THUNDERSTORMS WILL BE LATE WEDNESDAY INTO
THURSDAY AS A COLD FRONT MOVES ACROSS FROM THE WEST.

THE RELATIVE HUMIDITY WILL FALL INTO THE 50-60 PERCENT RANGE THIS
AFTERNOON...THEN RECOVER TO 90-100 PERCENT TONIGHT. THE RH WILL THEN
FALL TO 45-55 PERCENT FOR TUE AFTERNOON.

HAINES INDICES WILL REACH 3 TO 4 THIS AFTERNOON...4 TO 5 FOR TUE
AFTERNOON.

SOUTHWEST WINDS WILL INCREASE TO 10-20 MPH THIS AFTERNOON...THEN
WILL BECOME SOUTHWEST AT LESS THAN 5 MPH TONIGHT. WINDS WILL BECOME
SOUTH TO SOUTHWEST ON TUE...AT 10-15 MPH.

&&

.HYDROLOGY...
ISOLATED TO SCATTERED SHOWERS/STORMS ARE EXPECTED TO DEVELOP ONCE
AGAIN TODAY...WHICH COULD LEAD TO LOCALLY HEAVY DOWNPOURS. THIS
COULD LEAD TO MINOR FLOODING ISSUES...ESP FOR SOUTHERN AREAS SHOULD
ANY CONVECTIVE ELEMENTS TRAIN/BACKBUILD.

A WARM AND HUMID AIR MASS WILL REMAIN OVER THE REGION THROUGH MUCH
OF THE UPCOMING WEEK. THERE IS A CHANCE OF MAINLY AFTERNOON AND
EVENING SHOWERS AND THUNDERSTORMS ALMOST EACH DAY...WITH THE
GREATEST THREAT EXPECTED LATE WED INTO WED NT. THUNDERSTORMS WILL
CONTINUE TO PRODUCE HEAVY DOWNPOURS WITH MOIST AIR MASS IN PLACE.
