AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
704 AM EDT TUE SEP 10 2013
.SYNOPSIS...
MUCH WARMER AIR WILL STREAM INTO THE AREA TODAY ON SOUTHWEST
WINDS. A FRONT BOUNDARY WELL TO THE NORTH MAY TRIGGER A FEW
SHOWERS AND THUNDERSTORMS...ESPECIALLY OVER THE MOHAWK VALLEY AND
CATSKILLS THIS AFTERNOON. THE WARM AIR WILL HOLD OVER THE AREA INTO
WEDNESDAY AT LEAST.
&&
.NEAR TERM /THROUGH TONIGHT/...
FNTL BNDRY PUSHES NORTH OF THE AREA THIS MRNG AS CONV FIRES ALONG
THE FNT. LOOKS LIKE THE BEST CHANCE FOR ANY TRWS WILL BE NORTH OF
THE AREA...ALTHOUGH A FEW MAY LEAK INTO THE NRN ZONES...AND OVER
THE WRN CATS WHERE A WEAK SFC TROF SETS UP. DEW PTS POOL OVER THE
NRN ZONES NEARER THE FNT AND FCSTD CAPES APRCH 3000 J/KG WITH LTL
IF ANY CIN. NEG FACTOR FOR CONV IS THE LACK OF ANY LRG SCALE
FRCG...SO ANY CONV THAT FIRES WILL LIKELY BE A RESULT OF PRVS CONV
BNDRIES...TERRAIN...OR THE LEE TROF NEAR THE CATS. WHILE SHEAR IS
MODERATE...LRG AMT OF AVBL ENERGY MEANS ANY CELLS THAT FIRE WILL
NEED TO BE MONITORED.
TEMPS WILL MAKE A SIGNIFICANT RISE FROM MON WITH AREAS ALONG THE
LAKE PLAIN AND IN THE RVR VLYS SURPASSING 90F. MODERATING BREEZE
WILL HELP WITH THE COMFORT ALONG THE RIDGES NEAR THE FINGER LAKES
AND IN THE CATS.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
FLAT RDG HOLDS OVER THE AREA THRU MUCH OF THE SHRT TERM. WED WILL
BE ANOTHER WRM DAY WITH PLENTY OF INSTABILITY BUT LIMITED FRCG AND
WITH A MID/UPR LVL WRM LYR RESULTING IS SOME CAPPING.
COLD FNT OVER THE GREAT LAKES MVES SLOWLY EAST THEN STALLS NEAR OR
OVER THE AREA ON THU AS A WV DLPS ALNG IT. PSN OF THE FNT WILL BE
KEY BUT CERTAINLY THERE WILL BE CONV FIRING WITH DEEP MOISTURE AND
PWATS APRCHG 2 INCHES. LOOKS LIKE THERE WILL BE THE PTNL FOR A
GOOD SOAKING THU...ESP OVER THE NRN AND WRN PARTS OF THE FCST AREA
THU.
TEMPS ON WED WILL BE BACK INTO THE LOW 90S IN THE LWR ELEVATIONS
WITH H8 TEMPS ARND 20C. THUS WILL BE SOMEWHAT COOLER AS HGT LWRS
AND CLD CVR INCREASES.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
340 AM UPDATE...
FEW CHANGES MADE THE EXTENDED FCST THIS MORNING AS NEW 00Z
GUIDANCE AGREES WELL WITH EARLIER FCST TRENDS. DEEP UPPER CLOSED
LOW TO BE OVER THE REGION AT THE START OF THE PERIOD WHICH WILL
LIKELY LEAD TO DIURNAL INSTABILITY SHWRS FRI AFTERNOON. HEADING
INTO THE WEEKEND...BOTH THE 00Z GFS AND ECMWF MODELS SHOW STRONG
SURFACE HIGH PRESSURE BUILDING INTO THE REGION FOLLOWING THE UPPER
TROUGH/S DEPARTURE TO THE EAST. AS THIS FEATURE MOVES INTO THE
AREA...EXPECT A FAIRLY COOL AIRMASS FOR THIS TIME OF YEAR WITH
LATEST GUIDANCE OFFERING HIGHS IN THE UPPER 50S TO LOWER 60S
THROUGH THE BEGINNING STAGES OF THE UPCOMING WEEKEND. FOLLOWING
THIS...MODELS BEGIN TO DIVERGE BY EARLY NEXT WEEK AS THE ECMWF
SHOWS A FAIRLY STRONG POSITIVELY TILTED UPPER TROUGH WORKING
THROUGH THE REGION BEGINNING EARLY MONDAY MORNING...WITH
ASSOCIATED SHWR ACTIVITY ACROSS THE AREA THROUGH THE COURSE OF THE
DAY. THE GFS HOWEVER KEEPS THE BULK OF SHORTWAVE ENERGY DISPLACED
TO OUR NORTH ACROSS SOUTHERN CANADA ALONG WITH ALL APPRECIABLE
PRECIP. FOR NOW...HAVE MAINTAINED A LOW CHC MENTION FOR SHWR
ACTIVITY BASED ON MODEL DISAGREEMENT AND DISTANCE INTO THE FCST.
BEYOND THIS...HIGH PRESSURE TO MOVE BACK INTO THE REGION WITH
DRYING CONDITIONS EXPECTED BY TUESDAY.
2 PM UPDATE... FOLLOWED WPC GUIDANCE. MODELS IN GOOD
AGREEMENT. ON A SEESAW WITH SHOWERS AND HEAT TUESDAY TO THU NGT
THEN THE COLD FRONT FRONT GOES THROUGH. A DEEP UPPER LEVEL LOW
MOVES INTO THE NE US. A DEEP NW FLOW AND 850MB TEMPS BETWEEN 0 AND
+5C WILL SET OFF LAKE EFFECT SHOWERS FRIDAY AND FRIDAY EVENING.
COLD HIGH PRESSURE OVER THE WEEKEND WILL BRING SOME MORNING FOG
AND FROST AND CLEAR COOL AFTNS. WARMER ON MONDAY BUT A COLD FRONT
WITH SHOWERS AND THUNDERSTORMS WILL MOVE THROUGH.
&&
.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
STRONG MCS NOW WORKING EAST-SOUTHEAST ACROSS EASTERN LAKE ONTARIO.
THIS ACTIVITY WILL CONTINUE MOVING INTO THE FORECAST REGION WHERE IT
WILL LIKELY IMPACT THE NORTHERN TERMINALS OF RME AND SYR BETWEEN
11 AND 13Z. FURTHER SOUTH...ADDITIONAL SHWR/STORM ACTIVITY WILL
WORK THROUGH THE CENTRAL SOUTHERN TIER AND FINGER LAKES REGION
WITH SHORT DURATION MVFR/IFR RESTRICTIONS POSSIBLE AT REMAINING
CNY SITES THROUGH ROUGHLY 15Z.
SHIFTING TOWARDS THE LATE MORNING/AFTERNOON HRS...EXPECT WINDS TO
STRENGTHEN FROM THE SOUTHWEST AS REGION BECOMES ENVELOPED IN A
WARM SECTOR AIRMASS. WITH FAVORABLE MIXING...EXPECT SOUTHWEST
WINDS BETWEEN 10-15 KTS WITH GUSTS INCREASING TO NEAR 25 KTS
DURING THE LATE MORNING AND AFTERNOON. WINDS SHOULD BEGIN TO
DECREASE BY 22/23Z WITH LOSS OF DAYTIME HEATING. THUNDER POTENTIAL
FOR THE REST OF THE DAY REMAINS IN QUESTION BASED ON CURRENT
ACTIVITY AS HAVE ELECTED TO LEAVE MENTION OUT WITH MORNING UPDATE.
OVERNIGHT...THE COMBINATION OF CLEARING SKIES ALONG WITH MOIST
BOUNDARY LAYER CONDITIONS WILL SET THE STAGE FOR RADIATIONAL FOG
DEVELOPMENT IN FAVORED VALLEY LOCATIONS. AS A RESULT...ELM WILL
LIKELY SEE DEVELOPING IFR CONDITIONS AFTER 06Z WITH THESE TRENDS
CONTINUING THROUGH THE END OF THE FCST PERIOD.
OUTLOOK...
WED/THUR...MVFR IN SHRA/TSRA ACTIVITY ALONG COLD FRONT.
THUR NGT/FRI...MVFR IN LIGHT SHOWERS THEN BECOMING VFR LATE.
SAT...VFR. BUT MAYBE SOME EARLY MORNING IFR AT KELM.
&&
.CLIMATE...
