Flash Flood and Hail in New York, August 7, 2008
The passage of a strong upper level disturbance, combined with a moist and unstable air mass in place, led to the development of numerous thunderstorms across eastern New York State during Thursday afternoon on August 7th, some of which contained large hail. In addition, very heavy rainfall resulted in significant urban flash flooding in and near downtown Albany.

Area forecast discussion, Aug 7, 8:26 AM EST, 3 hours 4 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 926 AM EDT THU AUG 7 2008 .SYNOPSIS... A LARGE UPPER LEVEL LOW WILL PERSIST FROM EASTERN CANADA INTO THE NORTHEAST THROUGH AT LEAST THE NEXT FEW DAYS. SEVERAL DISTURBANCES WILL PASS THROUGH THE OUR REGION DURING THIS TIME. THIS WILL RESULT IN SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS...AND SLIGHTLY BELOW NORMAL TEMPERATURES. && .NEAR TERM /UNTIL 8 PM THIS EVENING/... A BROAD UPPER LEVEL TROF WILL CONTINUE TO DOMINATE OUR WEATHER. AN EMBEDDED DISTURBANCE DEPICTED ON WATER VAPOR IMAGERY IS CURRENTLY ADVANCING EASTWARD ACROSS WESTERN NEW YORK AND WILL MOVE INTO EASTERN NEW YORK AND WESTERN NEW ENGLAND LATER TODAY. THIS WILL RESULT IN SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPING THIS AFTERNOON. AS OF NOW IT APPEARS THE BEST CHANCE FOR MORE ROBUST THUNDERSTORMS WILL BE FROM THE CAPITAL REGION SOUTHWARD...AS THIS IS WHERE THE HIGHEST CAPE IS FORECAST. THE 12Z ALB SOUNDING MODIFIED YIELDS SBCAPE OF 2000 J/KG. A FEW LOW LEVEL INVERSIONS SHOULD EASILY BE MIXED OUT BY LATE MORNING...AS STRATUS CLOUD DECK ERODES. FLOW IN THE LOW TO MID LEVELS NOT VERY IMPRESSIVE...WITH ANY APPRECIABLE WIND GREATER THAN 30 KT CONFINED TO 500 MB AND HIGHER. STORM ENVIRONMENT WILL RESEMBLE PULSE-TYPE BUT WITH AMPLE FORCING FROM SHORT WAVE TROF MOVING THROUGH. HAIL WILL BE THE MAIN THREAT...WITH COLD POOL ALOFT /500 MB TEMPS OF -16C/ AND WBZERO HEIGHTS BELOW 9000 FEET. ALSO...850-500 MB LAPSE RATES IMPRESSIVE AROUND 7C/KM. SOME STORMS WITH STRONGEST CORES MAY PRODUCE SOME BRIEF WIND GUSTS...AS DCAPE FORECAST TO BE AROUND 750 J/KG. WILL MENTION ENHANCED WORDING IN HWO FROM CAPITAL REGION SOUTHWARD. TEMPS TODAY MAINLY MID TO UPPER 70S IN THE HIGHER ELEVATIONS AND UPPER 70S TO LOWER 80S IN THE VALLEYS. && .SHORT TERM /8 PM THIS EVENING THROUGH SUNDAY NIGHT/...

WENT WITH A BLEND OF MAV/FWC AND MET GUIDANCE THROUGHOUT THIS PERIOD...EXCEPT THE MET VALUES WERE TOO COOL FOR THE MAX TEMPERATURE ON FRIDAY SO FAVORED THE MAV/FWC VALUES. COOL TEMPERATURES CONTINUE ALOFT SO AGAIN HAVE INCLUDED THE POSSIBILITY OF SMALL HAIL WITH THUNDERSTORMS. && .LONG TERM /MONDAY THROUGH WEDNESDAY/...

LAWRENCE VLY REACHING YQB BY 12UTC SUNDAY. MEANWHILE THE NAM AND GEM HAVE SWUNG A 500 HPA TROF EAST OF RGN BY 12UTC SAT...AND HOLD THE MAIN CUTOFF UP OVER JAMES BAY. THE RESULT IS A MUCH SUNNIER AND WARMER SAT AND SUN. SAT IN THIS SCENARIO WOULD FEATURE SCT AFTN -SHRA/TSTMS...SUNDAY AS THE CUTOFF APPROACHES A SFC LOW DRAGS A CDFNT AND PRODUCES A RATHER SIGNIFICANT CONVECTIVE LINE DURING THE AFTN. LOOKING AT IPV ANOMALIES...BOTH MODELS START WITH THE SAME PV AREAS...AND DEVELOP THEM DIFFERENTLY. GIVEN THE NAM/GEM ALIGNMENT...IN THE WEEKEND PERIOD WILL LEAN TWRD NAM. MONDAY THE GFS HAS THIS FIRST CUTOFF IS SOMEWHERE IN NE QUEBEC...AND DUMBELLING AROUND ANOTHER CUTOFF CENTER IN N HUDSONS BAY.

DUE TO THE TRAJECTORY OF THE AIRMASS...GFS ALLUDES TO THE UNIQUE AUGUST SITUATION WE GET SOME YEARS...MAJOR WAA FROM CANADA. && .AVIATION /13Z THURSDAY THROUGH MONDAY/... A WIDE UPPER TROF OVER EASTERN CANADA WILL CONTINUE TO DOMINATE THE WEATHER OVER THE REGION WITH COLD AIR ALOFT OVER FAIRLY WARM AND MOIST AIR AT THE SURFACE. FOG...WHICH HAS RESULTED IN LOCALIZED MVFR/IFR VISIBILITY...WILL MIX OUT AND DISSIPATE BETWEEN 11Z AND 13Z...WITH VFR FLIGHT CONDITIONS PREVAILING THE REST OF THE DAY. HIGH AND MID LEVEL CLOUDS WERE STREAMING INTO THE REGION AHEAD OF A WAVE DEVELOPING ON THE FRONTAL SYSTEM IN THE OHIO VALLEY. ONCE THE SUN BEGINS HEATING THE AIRMASS WE CAN EXPECT CU TO FORM AND SCATTERED THUNDERSTORMS WILL DEVELOP AS THE DAY GOES ON. LOCALIZED MVFR/IFR MAY BE ENCOUNTERED IN SHOWERS AND THUNDERSTORMS AND SOME OF THE THUNDERSTORMS MAY CONTAIN SMALL HAIL. WINDS TODAY WILL GENERALLY BE FROM THE WEST 4 TO 8 KNOTS.

Heavy rainfall led to significant urban flooding in downtown Albany late Thursday afternoon. One to four inches of rainfall occurred within two hours across a small portion of downtown. This overwhelmed the storm drainage system within the city, flooding several streets. Hackett Boulevard and Northern Boulevard had water deep enough to submerge vehicles, with several cars swept away outside of the Hackett Dale apartments. In addition, water burst through a manhole on South Pearl Street near Arch Street, shooting water at least two stories high. Flooding also closed Holland Avenue, and water at least 8 inches deep was pouring over the curb on Broadway, near the State Department of Environmental Conservation building.
Numerous basements were also flooded within the city of Albany, as well as in portions of Guilderland, Delmar and Bethlehem.
