Area forecast discussion, Jul 17, 7:27 PM EDT, 2 hours 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
727 PM EDT FRI JUL 17 2009

.SYNOPSIS...
LOW PRESSURE WILL PASS OVER THE WESTERN SECTION OF THE TRI STATE
REGION OVERNIGHT. THIS SETS THE STAGE FOR A DRY WEEKEND WITH
TYPICAL MID SUMMER TEMPERATURES AS A FRONTAL BOUNDARY BECOMES
INACTIVE OFF THE COAST. THE FRONT IS EXPECTED TO BECOME ACTIVE
AGAIN ON MONDAY INTO AT LEAST THE MIDDLE OF NEXT WEEK RESULTING IN
A RETURN TO UNSETTLED WEATHER.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
SHORT RANGE MODELS IN FAIR AGREEMENT. GFS AND REGIONAL GEM APPEAR
TO HAVE GOOD HANDLE ON THE SITUATION AND BASIS FOR THE FCST. LARGE
SYNOPTIC SCALE LOW SCALE MOVES INTO CHAMPLAIN VALLEY BY AM.

HEAVY RAIN OVERNIGHT IS LIKELY THE MAIN THREAT AND WILL MENTION
THIS IN THE HWO...THOUGH DO NOT BELIEVE QPF IS OVER AN INCH ON
AVERAGE.

SEVERE HAIL/WIND THREAT WILL LIKELY DIMINISH BY SUNSET.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
COLD FRONT PASSES EAST OF THE REGION BY SATURDAY MORNING WITH
ONLY A LOW CHANCE NORTH FOR ANY LEFT OVER PCPN IN THE EARLY
MORNING. WHILE THERES A LEFT OVER SURFACE TROUGH OVER THE
REGION...DONT FORESEE MUCH MORE THAN A FEW CONVECTIVE CU. TEMPS
ARE A BLEND OF NAM AND COOLER GFS MOS. LESS HUMIDITY AND TAD
COOLER FOR SUNDAY. OVERALL...LOOKS LIKE A GREAT MID-SUMMER
WEEKEND.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
FORECAST MODELS ARE SHOWING A POTENTIAL FOR AN EXTENDED PERIOD OF
UNSETTLED WEATHER DURING THIS TIME.

SYN OPTICALLY...AN UPPER LEVEL TROUGH OF LOW PRESSURE IS FORECAST TO
GRADUALLY DEEPEN EXTENDING S ACROSS THE WESTERN ATLANTIC TROPICAL
WATERS. A BOUNDARY OR FRONT IS FORECAST TO REMAIN NEARLY STATIONARY
JUST OFF THE NJ AND LONG ISLAND COAST AS SMALL WAVES OF LOW PRESSURE
RIPPLE N TO NE ALONG THIS FRONT BRINGING ROUNDS OF HEAVY SHOWERS AND
TSTMS IN A MARITIME TROPICAL AIR MASS.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
LOW PRESSURE APPROACHING FROM THE WEST...AND BOUNDARY LAYER WIND
FLOW BACKING TO THE EAST/SOUTHEAST. MOIST BOUNDARY LAYER WITH
SHRINKING T/TD SPREADS SETTING THE STAGE FOR STRATUS AND FOG
DEVELOPMENT. IN ADDITION...WILL NEED TO KEEP AN EYE ON ANY
UPSTREAM CONVECTION. LIKELY IFR CONDITIONS OVERNIGHT MOST
TERMINALS. COLD FRONT THEN PASSES TO THE EAST AND FLOW TURNS TO
THE SOUTHWEST...THEN WEST/NORTHWEST SATURDAY MORNING. ANY LOW
CLOUDS SCOUR OUT AS BOUNDARY LAYER DRIES...AND VFR CONDITIONS
PREVAIL THROUGH THE DAY.

OUTLOOK FOR 00Z SUN THROUGH WED...
SLOW MOVING UPPER LEVEL LOW WILL SPIN OVER THE GREAT LAKES
THROUGH MON...THEN OPEN UP AS IT EXITS. MAINLY VFR BUT PERIODS
OF SUB- VFR ARE POSSIBLE IN SHOWERS/TSTMS FOR QUITE SOME TIME.

&&

.MARINE...
OTHER THAN TSTMS TONIGHT...EXPECT RELATIVELY TRANQUIL WX THIS
WEEKEND. SEAS ON OCEAN MAY APPROACH 5 FT SATURDAY AFTERNOON...BUT
FOR NOW HAVE FORECAST BELOW WAVEWATCH MODEL GUIDANCE AND NO SMALL
CRAFT FOR SEAS. LESS WIND AND SEAS ON SUNDAY.

STATIONARY FRONT BECOMES ACTIVE NEXT WEEK...BUT STILL BELOW SCA
LEVEL CONDITIONS EXPECTED.

&&

.HYDROLOGY...
QPF OVERNIGHT IS EXPECTED TO BE FOCUSED ON THE WESTERN THIRD OF
THE HYDROLOGIC SERVICE AREA. BASIN AVERAGES HERE SHOULD BE NEAR AN
INCH WITH LOCALLY HIGHER AMOUNTS (2 INCHES) IN EMBEDDED
CONVECTION. THERE IS A POSSIBILITY OF LOCALIZED FLASH FLOODING
WITH THE CONVECTION...BUT TOO LOW A CHANCE AND LOCALIZED TO
WARRANT A FLOOD WATCH.
