AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
358 PM EDT FRI JUN 26 2009

.SYNOPSIS...
A WEAK COLD FRONT BUT ASSOCIATED STRONG UPPER LEVEL DISTURBANCE
WILL CONTINUE TO CROSS THE REGION TONIGHT. AN UPPER LEVEL LOW WILL
DEVELOP OVER AND JUST EAST OF THE REGION ON SATURDAY...AND WILL ONLY
DRIFT SLOWLY SOUTH AND EAST THROUGH THE WEEKEND...RESULTING IN
UNSETTLED WEATHER. WHILE IT WILL NOT BE RAINING THE ENTIRE
TIME...SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP EACH
DAY...MAINLY DURING THE AFTERNOON AND EVENING HOURS. THE UNSETTLED
PATTERN WILL CONTINUE INTO NEXT WEEK...AS YET ANOTHER UPPER LEVEL
LOW APPROACHES FROM THE GREAT LAKES.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
SEVERE THUNDERSTORM WATCH 516 CONTINUES FOR MUCH OF THE THE AREA
THROUGH 7 PM EXCEPT FOR WASHINGTON/RENSSELAER/COLUMBIA AND SOUTHERN
VERMONT/BERKSHIRE. A POTENT UPPER LEVEL DISTURBANCE MOVING ACROSS
THE GREAT LAKES HAS TRIGGERED CLUSTER OF SEVERE THUNDERSTORMS
UPSTREAM OF OUR AREA.

THE ATMOSPHERE HAS HAD ENOUGH TIME TO RECOVER AND DESTABILIZE IN
WAKE OF CLOUDS/RAIN THAT MOVED THROUGH THIS MORNING/EARLY AFTERNOON.
GENERALLY 1000-2000 J/KG OF SBCAPE NOTED ON LAPS ANALYSIS. DEEP
LAYER 0-6 KM SHEAR IS MAINLY UNIDIRECTIONAL 30-40 KT...SO STORM
ORGANIZATION SHOULD OCCUR. MAIN QUESTION IS IF THE CURRENT SEVERE
CLUSTERS OF CONVECTION ACROSS NORTHERN/CENTRAL NY MAINTAIN THEIR
STRENGTH ONCE THEY MAKE IT INTO OUR REGION. MAIN CLUSTER THAT
DEVELOPED JUST WEST OF ULSTER COUNTY HAS NOW EXPANDED EASTWARD INTO
SOUTHERN ULSTER/DUTCHESS/LITCHFIELD COUNTIES. OTHER ACTIVITY
UPSTREAM IN NORTH CENTRAL NY AND THE ST LAWRENCE VALLEY MAY REACH
NORTHERN AND CENTRAL PORTIONS OF THE AREA AS WELL. SO WILL MENTION
LIKELY POPS FOR LATE AFTERNOON/EARLY EVENING.

COVERAGE AND INTENSITY OF CONVECTION SHOULD DIMINISH LATER THIS
EVENING WITH LOSS OF DAYTIME HEATING. THE UPPER LEVEL TROF DIGGING
ACROSS THE NORTHEAST CONUS IS FORECAST TO CUT OFF AT 500 MB TONIGHT
AND DRIFT SOUTHWARD INTO EASTERN NY/WESTERN NEW ENGLAND BY SAT
MORNING. STILL PLENTY OF CLOUDS AROUND OVERNIGHT...WITH A FEW
BREAKS. MIN TEMPS GENERALLY EXPECTED TO BE IN THE UPPER 50S TO LOWER
60S.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/...
THE AFOREMENTIONED CUT-OFF LOW WILL DOMINATE OUR WEATHER THROUGH THE
WEEKEND...AS IT ONLY GRADUALLY DRIFTS SOUTHEAST ACROSS SOUTHERN NEW
ENGLAND AND EVENTUALLY OFF THE COAST BY LATE SUNDAY. EASTERN NEW
YORK AND WESTERN NEW ENGLAND WILL BE ON THE WESTERN PERIPHERY OF THE
CUT-OFF...SO THERE IS LESS OF A THREAT FOR SEVERE WEATHER AND
TORRENTIAL RAINFALL THAT WE HAVE SEEN THE LAST COUPLE DAYS.
STILL...IT WILL BE RATHER GLOOMY WITH A FEW PERIOD OF SHOWERS AND
AFTERNOON/EVENING THUNDERSTORMS. SBCAPE VALUES AROUND 500-750 J/KG
ON SAT AND 250-500 J/KG ON SUN...SHOULD RESULT IN GENERAL STORMS
WITH NOT MUCH VERTICAL DEVELOPMENT. WILL MENTION THE HIGHEST POPS
DURING THE AFTERNOON AND EARLY EVENING HOURS BOTH SAT AND SUN...AS
PIECES OF ENERGY PIVOT AROUND THE UPPER LOW. GENERALLY LOTS OF
CLOUDS EXPECTED TOO...BUT THERE WILL BE SOME OCCASIONAL BREAKS AS
WELL.

TEMPS WILL AVERAGE CLOSE TO NORMAL...WITH CLOUDS/SHOWERS/LOW LEVEL
MOISTURE WILL RESULT IN SLIGHTLY WARMER THAN NORMAL MIN TEMPS AND
SLIGHTLY COOLER THAN NORMAL MAX TEMPS.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
THE EXTENDED PERIOD WILL BE DOMINATED BY A LARGE SLOW MOVING CUTOFF
LOW AT 500 HPA. ON MONDAY...THE UPPER LOW WILL BE SITUATED OVER THE
NORTHERN GREAT LAKES AND ONLY MAKE SLOW PROGRESS EASTWARD TOWARDS
NORTHERN LOWER MICHIGAN. THE CYCLONIC FLOW AROUND THE LOW WILL ALLOW
FOR MAINLY DIURNAL DRIVEN SCT SHOWERS ACROSS OUR CWA. AT THIS
POINT...THE UPPER LOW SHOULD BE FAR ENOUGH AWAY TO LIMIT STRONG
INSTABILITY...SO WILL NOT INCLUDE THUNDER AT THIS POINT. BY
TUESDAY...THE UPPER LOW WILL BE APPROACHING WESTERN LAKE ERIE. HAVE
ONCE AGAIN INCLUDED HIGH CHC POPS IN THE FORECAST...AND WILL ALSO
INCLUDE THUNDER...AS THE GFS HAS FORECASTED LI OF 0 TO -2 C. THE
UPPER LOW WILL CONTINUE TO MOVE ACROSS SOUTHERN ONTARIO BY
WEDNESDAY...AND ACROSS THE NORTH COUNTRY OF NY BY THURSDAY. WILL
CONTINUE TO POST HIGH CHC POPS FOR THE ENTIRE CWA THROUGH THE
REMAINDER OF THE FORECAST PERIOD. THE BEST CHANCE FOR STRONGER
CONVECTION WOULD PROBABLY BE ON WEDNESDAY AFTN...AS THE PASSING OF
THE SFC BOUNDARY WILL ALSO HELP FOCUS THE CONVECTION....AS WELL AS
FORECASTED LIS OF 0 TO -3 C.

MAX TEMPS WILL CONTINUE TO RUN A FEW DEGREES BELOW NORMAL ALL WEEK
WITH VALLEY HIGHS IN THE MIDDLE TO UPPER 70S...AS THE SCT
SHOWERS...PARTLY TO MOSTLY CLOUDY SKY COVER...AND LOWER UPPER LEVEL
HEIGHTS...WILL ALL PROMOTE COOLER THAN NORMAL TEMPERATURES.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
VFR CONDITIONS WILL PREVAIL EARLY THIS AFTERNOON...THROUGH
21-22Z...THEN SCATTERED STRONG THUNDERSTORMS WITH BRIEF PERIODS
OF IFR CONDITIONS WILL AFFECT THE AIRPORTS AROUND 22-24Z. LINGERING
LIGHT SHOWER ACTIVITY WILL CONTINUE WITH MVFR/VFR CONDITIONS
THROUGH ABOUT 01-03Z. VFR CONDITIONS WILL PREVAIL AT ALL SITES
THROUGH 06-09Z...WHEN SOME SCATTERED SHOWERS WILL SPREAD FROM
NORTH TO SOUTH DURING ASSOCIATED WITH ANOTHER UPPER LEVEL
SYSTEM...DURING THE EARLY MORNING HOURS AFTER 06-09Z. PREVAILING
CONDITIONS WILL BE VFR...SO JUST INDICATING VCSH AFTER 06-09Z.
SOME MVFR CLOUD PERIODS THROUGH ABOUT 14Z...THEN RETURNING TO VFR
AFTER 14Z.

WINDS WILL BE LIGHT SOUTH TO SOUTHWEST AT 10 KT OR LESS EARLY THIS
AFTERNOON... SHIFTING TO WEST AND NORTHWEST LATE THIS AFTERNOON
AND EVENING...BECOMING NORTH TO NORTHWEST TOMORROW MORNING.

SAT-WED...VFR/MVFR...SCATTERED MAINLY AFTN SHOWERS/TSTMS.

&&

.FIRE WEATHER...
SHOWERS AND THUNDERSTORMS ARE LIKELY FOR MUCH OF THE REGION THROUGH
THIS EVENING. UNSETTLED WEATHER WITH PERIOD OF SHOWERS AND A FEW
THUNDERSTORMS ARE EXPECTED FOR SATURDAY AND SUNDAY. DAMP CONDITIONS
SHOULD PERSIST INTO NEXT WEEK AS WELL.

RELATIVE HUMIDITY VALUES WILL RISE TO NEAR 100 PERCENT
TONIGHT...THEN DROP TO BETWEEN 50 AND 65 PERCENT ON SATURDAY. RH
VALUES WILL ONCE AGAIN RISE TO NEAR 100 PERCENT SATURDAY NIGHT.

WINDS WILL BE GENERALLY WEST AROUND 5 MPH TONIGHT...THEN SHIFT TO
THE NORTH-NORTHWEST ON SATURDAY AND INCREASE TO AROUND 5 TO 10 MPH.
WINDS SATURDAY NIGHT WILL BE NORTH-NORTHWEST AROUND 5 MPH.

&&

.HYDROLOGY...
SCATTERED THUNDERSTORMS THURSDAY EVENING APPEARED TO HAVE LITTLE
EFFECT ON MAIN STEM RIVERS. MORE SHOWERS AND STORMS ARE LIKELY THIS
AFTERNOON. SOME OF THESE COULD ONCE AGAIN CONTAIN HEAVY RAINFALL
WITH LOCAL AMOUNTS EXCEEDING AN INCH. IT IS UNLIKELY THEY WOULD HAVE
A SIGNIFICANT IMPACT ON MAIN STEM RIVERS...BUT SMALLER STREAMS COULD
SEE QUICK RISES IN A FEW PLACES. LOCAL DOWNPOURS COULD CAUSE
SIGNIFICANT PONDING OF WATER ON ROADWAYS AND AREAS OF POOR DRAINAGE.

AVERAGE RAINFALL BASIN FORECASTS ARE EXPECTED TO AROUND A QUARTER
INCH OR LESS THROUGH TONIGHT.

THERE IS THE THREAT OF ADDITIONAL SHOWERS AND PERHAPS AN ISOLATED
THUNDERSTORM BOTH WEEKEND DAYS BUT ONCE AGAIN THE ACTIVITY LOOKS TO
BE SCATTERED. AT THIS POINT...THESE SHOWERS AND STORMS DO NOT APPEAR
TO POSE ANY SERIOUS HYDROLOGICAL PROBLEMS THROUGH THE WEEKEND.

UNSETTLED WEATHER IS FORECAST INTO NEXT WORK WEEK WITH MORE SHOWER
AND THUNDERSTORM ACTIVITY. SOME OF THESE COULD CONTAIN HEAVY
RAINFALL.

AND FORECAST RIVER STAGES AND LAKE ELEVATIONS...PLEASE VISIT THE
