Area forecast discussion, Jun 13, 2:44 PM EST, 1 hour 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
344 PM EDT SAT JUN 13 2009

.SYNOPSIS...
AN UPPER AIR DISTURBANCE CROSSING THE AREA THIS AFTERNOON WILL MOVE
EASTWARD OVERNIGHT. A WEAK AREA OF HIGH PRESSURE WILL BUILD OVER
THE REGION SUNDAY. ANOTHER DISTURBANCE WILL APPROACH SUNDAY NIGHT
AND BRING UNSETTLED WEATHER FOR THE BEGINNING OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
THE SLOW-MOVING THUNDERSTORM WITH FLOODING ACTION ACROSS THE
REGION SATURDAY AFTERNOON WILL SLOWLY DIMINISH EARLY TONIGHT WITH
THE LOSS OF DAYTIME HEATING. RAINFALL HAS BEEN SPOTTY, BUT
EXCESSIVE IN SOME AREAS WITH 1 TO 2 INCHES PER HOUR RATES BEING
ESTIMATED AT TIMES BY KDIX. THE LIGHT WINDS AT THE MID LEVELS AND
DAYTIME HEATING HAVE COMBINED TO PRODUCE THESE POOR CONDITIONS.
PAY ATTENTION TO STATEMENTS AND WARNING BEING ISSUED FROM OUR
OFFICE, AS THE SITUATION IS ONGOING AND CHANGING QUICKLY AT TIMES.
SEVERAL FLOOD WARNING ARE PRESENTLY IN EFFECT.

LATER TONIGHT, SKIES SHOULD BECOME PARTLY CLOUDY. SINCE THE SFC
WINDS WILL BE LIGHT AND THE DRY AIR SHOULD NOT MOVE IN TOO
QUICKLY, PATCHY FOG WILL DEVELOP OVERNIGHT. IT MAY BECOME DENSE AT
TIMES, AND I HAVE CHOSEN TO INCLUDE IT IN THE PUBLIC GRIDS FOR
TONIGHT.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/...
IT IS STILL LOOKING LIKE THE FIRST RATER DRY DAY FOR OUR AREA WILL
BE SUNDAY WITH A WEAKENING HIGH PRESSURE AREA DRIFTING IN FROM THE
GREAT LAKES REGION DURING THE DAY. WHILE SFC WINDS WILL BE LIGHT,
THE WINDS OFF THE DECK WILL TURN TO N OR NW AND THIS WILL BRING
SOME DRIER AIR TO THE REGION. TEMPERATURES WILL BE IN THE UPPER
70S TO LOW 80S IN MOST AREAS, COOLER IN THE SOUTHERN POCONOS.

ANOTHER VORT MAX IN THE NW FLOW WILL ROLL TOWARD OUR REGION SUNDAY
NIGHT THROUGH MONDAY. THE GFS/ECMWF MODELS ARE STILL DRY FOR SUN
NIGHT ACROSS THE AREA WHILE THE NAM IS OFFERING SOME LIGHT QPF. I
HAVE KEPT THE FCST DRY FOR NOW WITH ONLY SLGT CHC POPS NORTH AND
WEST. A BETTER CHC FOR SHOWERS AND THUNDER WILL BE ACROSS THE AREA
MONDAY WITH THE BEST DYNAMICS AND SOME LIMITED CAPE VALUES OVER
THE REGION.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
MOSTLY FAIR WEATHER WILL BE OVER THE REGION DURING THE BEGINNING
OF THE EXTENDED PERIOD AS HIGH PRESSURE WILL BE OFF TO THE
NORTHEAST AND AN UPPER RIDGE WILL BE APPROACHING FROM THE WEST. A
SLIGHT CHC OF SHOWERS WILL STILL BE KEPT IN THE GRIDS FOR NOW, AS
THIS WORKS BEST WITH OUR SURROUNDING OFFICES. THE SYSTEM EXITING
AT THE END OF THE SHORT TERM PERIOD MAY LINGER INTO EARLY TUESDAY.

AFTER A PERIOD OF FAIR WEATHER WEDNESDAY, THE NEXT UPPER TROUGH
WILL APPROACH AND DEEPEN ACROSS OUR AREA. MODELS ARE SHOWING THE
POSSIBILITY OF SHOWERS AND THUNDER IN NW FLOW OVER OUR AREA SO
SLIGHT CHC POPS WED NIGHT WILL REMAIN AND CHC POPS WILL FILL OUT
MOST OF THE REST OF THE EXTENDED PERIODS FOR NOW. TEMPERATURES
DURING THE EXTENDED PERIOD WILL IN GENERAL BE BELOW NORMAL WITH
DAYTIME HIGH TEMPERATURES IN THE MID TO UPPER 70S IN MOST AREAS.
SOME LOW 80S ARE IN THE GRIDS FOR FRI AND SAT NEXT WEEKEND, WELL
SEE.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

WITH A FRONTAL ZONE SITTING TO OUR SOUTH AND MID LEVEL ENERGY
DROPPING IN FROM THE NORTHWEST, THE RELATIVE QUIET FROM EARLY
TODAY HAS TURNED INTO A VERY ACTIVE AFTERNOON FOR SHOWERS AND
TSTMS. CONDITIONS REMAIN VFR AT ALL TAF SITES THIS AFTERNOON EXCEPT
IN ANY SHOWERS/TSTMS, WHERE THEY DETERIORATE TO MVFR/IFR VERY
QUICKLY. THE E TO NE FLOW HAS PROTECTED SOUTHERN AND COASTAL AREAS
WHERE NOTHING MORE THAN SOME MID AND HIGH LEVEL CLOUDS ARE BEING
REPORTED. THE SHOWERS/TSTMS, WHICH ARE MOVING VERY SLOWLY BECAUSE OF
THE LIGHT STEERING WINDS ALOFT, WILL CONTINUE INTO THE EVENING
HOURS. ONCE THEY END, ABUNDANT LOW LEVEL MOISTURE WILL CAUSE CIGS
AND VSBYS TO LOWER OVERNIGHT. IN THE PREDAWN HOURS, MANY AREAS
WILL HAVE IFR/LIFR CONDITIONS. THIS WILL IMPROVE RAPIDLY AFTER
SUNRISE WITH VFR CONDITIONS EXPECTED EVERYWHERE BY MID MORNING.
HIGH PRESSURE PUSHING IN FROM THE NW WILL BRING SLIGHTLY DRIER AIR
AND VFR WEATHER SUNDAY AFTERNOON INTO MONDAY, ALTHOUGH THERE COULD
BE ADDITIONAL SHOWERS/TSTMS MONDAY AFTERNOON INTO MONDAY NIGHT AS
ANOTHER FRONTAL ZONE CROSSES OUR AREA.

OUTLOOK...
HIGH PRESSURE THEN FORECAST TO REBUILD INTO THE AREA WILL BRING
GENERALLY FAIR VFR WEATHER TUESDAY THROUGH WEDNESDAY. A WARM FRONT
COULD CAUSE A DOWNTURN IN FLYING CONDITIONS AGAIN FOR THE END OF
THE WEEK.

&&

.MARINE...
CONDITIONS CONTINUE BELOW SMALL CRAFT ADVISORY CRITERIA AND SHOULD
REMAIN SO AT LEAST THROUGH MONDAY NIGHT, DESPITE A PERSISTENT
ONSHORE FLOW. THIS FLOW SHOULD BE LIGHT ENOUGH TO PRECLUDE 5 FOOT
SEAS. WAVEWATCH DOES EVENTUALLY BUILD SEAS TO 5 FEET AND HIGHER
LATE TUESDAY OR TUESDAY NIGHT AS WINDS VEER TO THE SOUTHEAST AND
SOUTH. THIS COULD BE OVERDONE, SINCE THE GFS DEVELOPS A LOW TO
OUR SOUTH AND MOVES IT EAST. IT INTERACTS WITH STRONG HIGH
PRESSURE TO OUR NORTH, WHICH CAUSES A TIGHTENED PRESSURE GRADIENT.
OTHER COMPUTER MODELS KEEP THE LOW MUCH WEAKER AND FARTHER SOUTH
AND KEEP US UNDER THE INFLUENCE OF THE HIGH TO OUR NORTH. WE WILL
CONTINUE TO MONITOR AND, HOPEFULLY, THE MODELS WILL HONE IN ON A
SOLUTION AS THIS WEEKS WEATHER UNFOLDS.

Event by event

2 thunderstorm wind, 2 hail, 1 funnel cloud. Local standard time, as filed.

Thunderstorm Wind, Kent

When: June 13, 4:00 PM EST to 4:05 PM EST
Where: Kent County, 1.05 mi WNW of Vernon to 2.73 mi ENE of Hickman
Measured: 70 kt (81 mph) estimated gust
Property damage: $100,000
Crop damage: $100,000
Reported by: NWS Storm Survey
Coordinates: 38.885, -75.669

A severe thunderstorm produced a swath of straight-line wind damage up to one-half mile wide in spots from just west of Harrington in southwestern Kent County in Mispillion Hundred south to the town of Greenwood in northern Sussex County. Damage began on High Stump Road west of Harrington where a few tree tops were snapped and a few other trees were uprooted. An old barn was blown down, with its roofing material blown up to one-half mile away. Farther south, two trees were blown down along Burrsville Road. Wind damage continued into Sussex County.

Corn was stripped to the stalk on many fields within the damage swath, resulting in a total loss in some cases. Wheat and barely fields also suffered substantial damage. Combined Kent and Sussex County crop losses could easily total several hundred thousand dollars. Maximum wind speeds were estimated at 80 MPH.

Thunderstorm Wind, Sussex

When: June 13, 4:05 PM EST to 4:15 PM EST
Where: Sussex County, 4.13 mi WNW of Greenwood to Greenwood
Measured: 70 kt (81 mph) estimated gust
Property damage: $100,000
Crop damage: $100,000
Reported by: NWS Storm Survey
Coordinates: 38.825, -75.650

A severe thunderstorm produced a swath of straight-line wind damage up to one-half mile wide in spots from southwestern Kent County into western Sussex County. Most of the wind damage occurred in Northwest Fork Hundred. Maximum wind gusts were estimated at 80 mph and caused property as well as substantial crop damage. One home sustained substantial damage. There was widespread crop damage from large hail.

Wind damage in Sussex County started near County Route 16 near Blanchard. The most significant damage occurred parallel to McDowell Road east of Woodbridge Road. A porch roof was ripped away from a wood-framed farm house, and a steel antenna tower next to the house was bent. A tree near the house was blown down, and a large chicken barn near the house collapsed. Farther east, another steel antenna tower was bent, and some shingles were torn off the roof of a nearby house.

Corn was stripped to the stalk on many fields within the damage swath, resulting in a total loss in some cases. Wheat and barely fields also suffered substantial damage. Crop losses mainly from hail could easily total several hundred thousand dollars.

Tree damage was also noted in the town of Greenwood. Small to medium sized limbs were torn away along Minor Street in downtown Greenwood. Some lawn furniture was blown around, and streets and driveways were littered with leaves. Some funnel clouds were reported, but they did not touch down.

Funnel Cloud, Sussex

When: June 13, 4:05 PM EST
Where: Sussex County, 1.95 mi WNW of Greenwood
Reported by: Trained Spotter
Coordinates: 38.806, -75.615

A funnel cloud was sighted during a severe thunderstorm in northwest Sussex County. A National Weather Service damage survey indicated that all of the wind damage was straight line and that the funnel did not touch the ground.

Hail, Sussex

When: June 13, 4:10 PM EST
Where: Sussex County, 2.58 mi WNW of Greenwood
Measured: 1 in hail
Crop damage: $300,000
Reported by: NWS Storm Survey
Coordinates: 38.814, -75.624

A severe thunderstorm also produced large hail west of Greenwood in Sussex County. There was widespread crop damage from large hail. The hail caused corn to be stripped to the stalk. Wheat and barely fields also suffered substantial damage. Crop losses could easily total several hundred thousand dollars. In the nearby garden, strawberry plants were pulverized by the hail. The most significant hail damage occurred parallel to McDowell Road east of Woodbridge Road. Hail size was estimated.

Hail, Sussex

When: June 13, 5:14 PM EST
Where: Sussex County, 2.99 mi SW of Sycamore
Measured: 1 in hail
Reported by: Trained Spotter
Coordinates: 38.570, -75.520

Quarter size hail fell in Broad Creek Hundred northeast of Laurel.

What these are

Thunderstorm Wind: Winds from a thunderstorm of 50 knots (58 mph) or more, or lower winds that caused damage or casualties. Measured gusts are marked MG, estimated EG.
Funnel Cloud: A rotating column of cloud extending from a thunderstorm that did not reach the ground.
Hail: Hail three-quarters of an inch or larger, or smaller hail that caused damage, filed with the largest stone measured.

After NWS Directive 10-1605, the rules offices file Storm Data by.
