Area forecast discussion, Jul 25, 2:31 PM EDT, 2 hours 42 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
231 PM EDT MON JUL 25 2011

.SYNOPSIS...
AN UPPER LEVEL DISTURBANCE WILL PASS THROUGH THE REGION ON
TUESDAY...AND MAY TRIGGER A FEW THUNDERSTORMS. HIGH PRESSURE WILL
BUILD IN FOR TUESDAY NIGHT AND WEDNESDAY...WITH FAIR WEATHER. THE
CHANCE FOR SCATTERED SHOWERS AND THUNDERSTORMS WILL RETURN ON
THURSDAY AS A WARM FRONT APPROACHES THE AREA.

&&

.NEAR TERM /THROUGH TONIGHT/...
LINE OF TSRA OVER THE SRN TIER MOVG INTO NE PA. SFC BASED INSTABILTY
IS BEST ACRS THESE AREAS...AS OUTFLOW FROM MCS WHICH MOVD ACRS LAKE
ONTARIO HAS STABILIZED MUCH OF THE FINGER LAKES/WRN MOWHK VLY AND
NRN SUSQ RGN. MARINE LAYER ACRS FAR ERN ZONES WILL LIMIT ERN XTNT
OF THE SVR POTNL THERE. WILL MONITOR FOR POTNL OF ADDNL SCT
ACTIVITY AHEAD OF THE CDFNT ACRS CNTRL NY. OTRW ACTIVITY XPCTD TO
DIMINISH THIS EVNG.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
ANOTHER S/WV AND SFC BNDRY PASSES ON TUE. WIND FIELDS LOOK GOOD FOR
SVR BUT CVRG IS A QUESTION. CAPES APRCHNG 750-1000 J/KG. WILL
KEEP CHC POPS FOR TSRA ON TUE. HIGH PRES BUILDS INTO THE AREA TUE
NGT/WED...WITH WED LOOKING LIKE A REALLY NICE DAY WITH LOWER RH'S
AND SEASONABLE TEMPS. MDL'S SUGGESTING POTNL FOR ANOTHER MCS ON
THU AS WMFNT APRCHS THE AREA. FOR NOW WILL JUST GO WITH CHC POPS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
DUE TO ACTIVE WEATHER...USED HPC GRID FOR EXTENDED PERIOD. WILL
LOOK AT IT AGAIN LATER.

DISCUSSION FROM YESTERDAY...FOLLOWED HPC/GFS GUIDANCE CLOSELY
THIS PD.

ON THE LARGE-SCALE...EXPANSIVE PERSISTENT CNTRL/SRN U.S. UPPER-LVL
RIDGE IS STILL PROGGED TO TEMPORARILY BUILD NEWD THU AND
FRI...BRINGING A RETURN TO HOT HUMID CONDITIONS. HOWEVER...NEXT
WEEKEND...THE CENTER OF THE RIDGE SHOULD GET SQUEEZED BACK TWDS
THE CNTRL CONUS...AS PROGRESSIVE NRN STREAM WAVES CARVE OUT A WEAK
TROUGH AXIS INTO THE NERN STATES.

AS FOR THE DAILY SENSIBLE WX...THE BEGINNING OF THE PD LOOKS DRY
WED NIGHT...WITH A SFC HI SLIDING OFF TO THE E.

A WARM FRONT IS PROGGED TO PUSH THROUGH THE AREA THU
AFTN/NIGHT...AND THIS SYSTEM COULD TOUCH OFF SOME HIT AND MISS
SHRA AND TSRA...DEPENDING ON THE EXACT DEGREES OF INSTABILITY
UPPER-LVL FORCING.

FRI LOOKS RATHER HOT AND HUMID FROM THIS VANTAGE PT...WITH MAX
TEMPS LIKELY PUSHING BACK INTO THE 90S FOR MANY AREAS. A FEW AMS
TSRA CAN'T BE RULED OUT IN THE AFTN/EVE...BUT MUCH OF THE DAY LOOKS RAIN-
FREE AT THIS PT. A BETTER CHANCE FOR CONVECTION MAY COME ON FRI
NIGHT...AND PERHAPS INTO EARLY SAT...WHEN A COLD FRNT IS PROGGED
TO COME THROUGH THE REGION FROM THE NW.

BEHIND THE AFOREMENTIONED COLD FRNT...THE LATTER PART OF NEXT
WEEKEND COULD WELL TURN OUT TO BE QUITE PLEASANT...WITH RAIN-FREE
WX...SEASONABLY WARM TEMPS (HIGHS IN THE 80S)...AND LOWER HUMIDITY
LEVELS.

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
MVFR CIGS AND SCATTERED SHOWERS AND THUNDERSTORMS OVER THE
CATSKILLS AND POCONO REGION ASSOCIATED WITH A WARM FRONT MOVE EAST
