Area forecast discussion, Jun 23, 7:38 PM EDT, 43 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
738 PM EDT SUN JUN 23 2013

.SYNOPSIS...
WARM AND HUMID CONDITIONS WILL BE THE NAME OF THE GAME THIS WEEK
AS BROAD SOUTHERLY FLOW PREVAILS ACROSS THE REGION. TEMPERATURES
WILL WARM WELL INTO THE MIDDLE TO UPPER 80S THROUGH LATE WEEK WITH
SHOWERS AND THUNDERSTORMS POSSIBLE EACH AFTERNOON AS THE ATMOSPHERE
BECOMES UNSTABLE.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
SHORT FUSED FLASH FLOOD WATCH NOW IN EFFECT FROM THE NORTHERN FINGER
LAKES EAST INTO THE WESTERN MOHAWK VALLEY...

RADAR BECOMING FAIRLY ACTIVE THIS AFTERNOON AS SHWRS/STORMS
CONTINUE TO DEVELOP ACROSS NORTHERN PORTIONS OF THE FCST AREA.
FAIRLY LIMITED SEVERE WX THREAT SO FAR WITH MAIN FOCUS TURNING TO
HYDROLOGIC CONCERNS AS DEVELOPING ACTIVITY CONTINUES TO TRAIN OVER
SAME AREAS REPEATEDLY (I.E. NORTHERN FINGER LAKES INTO WESTERN
THE MOHAWK VALLEY). DUAL-POL PRECIP ESTIMATIONS SUGGEST THAT 1-2"
OF RAIN HAS FALLEN ALREADY ACROSS PORTIONS OF SOUTHERN CAYUGA AND
SENECA COUNTIES...WITH ADDITIONAL HEAVY RAINS SPREADING EAST INTO
CENTRAL ONONDAGA...MADISION...AND SOUTHERN ONEIDA COUNTIES.
ATMOSPHERE REMAINS MODERATELY UNSTABLE AND EXTREMELY MOIST WITH
LATEST MLCAPE VALUES RANGING FROM 2000-2500 J/KG AND PWAT VALUES
APPROACHING 1.75" PER LATEST SPC MESOANALYSIS. DESPITE
INSTABILITY...WEAK CAPPING ALOFT AS EVIDENCED ON 12Z BUF SOUNDING
APPEARS TO BE KEEPING CONVECTIVE DEVELOPMENT JUST BELOW SEVERE
THRESHOLDS AT THE MOMENT. AS ACTIVITY CONTINUES TO DEVELOP
SOUTHWEST...GREATER INSTABILITY WILL BE AVAILABLE AS A RESULT OF
TEMPS HOVERING IN THE UPPER 80S AND LOWER 90S THIS AFTERNOON WHICH
MAY ALLOW MORE ROBUST DEVELOPMENT AS THE LATE AFTERNOON HRS
CONTINUE ON. IF STORMS WERE TO EVENTUALLY BECOME SEVERE...A FAIR
AMOUNT OF DRY AIR ALOFT ALONG WITH MODERATELY UNSTABLE CONDITIONS
SHOULD ALLOW FOR A WIND AND HAIL THREAT.

CONVECTIVE ACTIVITY SHOULD BEGIN TO DIE OFF LATER THIS EVENING
WHICH WILL BE FOLLOWED BY DECREASING POPS AND CLEARING SKIES
ALOFT. THE COMBINATION OF WET GROUNDS FROM AFTERNOON RAINFALL
ALONG WITH MOIST AND HUMID BOUNDARY LAYER CONDITIONS WILL LIKELY
ALLOW FOR PATCHY VALLEY FOG DEVELOPMENT TOWARDS MORNING. OVERNIGHT
LOWS WILL FALL INTO THE LOWER TO MIDDLE 60S.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
A VERY ACTIVE PERIOD EXPECTED THROUGH THE SHORT TERM AS WARM HUMID
AIRMASS REMAINS IN PLACE ALONG WITH THE PASSAGE OF SEVERAL UPPER-
LEVEL DISTURBANCES ALOFT. MAIN ATTENTION STARTING OUT WILL BE ON
A NORTHWARD LIFTING UPPER CLOSED LOW NOW SEEN ACROSS THE CENTRAL
APPALACHIANS. LATEST MODEL GUIDANCE CONTINUES TO SHOW THIS FEATURE
LIFTING NORTH INTO OUR FCST REGION TOWARDS 12Z MONDAY WITH
SCATTERED SHWRS AND STORMS EXPECTED TO ONCE AGAIN AS THE DAYTIME
HEATING CYCLE PROGRESSES. FOR NOW...HAVE CAPPED POPS AT HIGH CHC
CATEGORY UNTIL CONVECTIVE TRENDS BECOME MORE FIRMLY ESTABLISHED
WITH ADDITIONAL MODEL GUIDANCE/REAL-TIME TRENDS. OVERALL SEVERE
THREAT APPEARS RATHER MINIMAL AS WINDS ALOFT WEAKEN AS SYSTEM
APPROACHES. THAT SAID...CONTINUED HYDRO CONCERNS ON MONDAY AS VERY
WARM AND MOIST AIRMASS REMAINS IN PLACE COUPLED WITH MOIST GROUNDS
FROM HEAVY RAINS WITH TODAY/S ACTIVITY.

MUCH OF THE SAME EXPECTED RIGHT INTO TUESDAY AND WEDNESDAY WITH
AFTERNOON SHWRS/STRMS LIKELY EACH DAY. OVERALL CONVECTIVE ACTIVITY
APPEARS TO BE STRONGLY TIED TO THE DIURNAL CYCLE WITH ACTIVITY
GRADUALLY WEAKENING EACH EVENING WITH LOSS OF DAYTIME HEATING.
EXPECT HIGHS THROUGH MIDWEEK TO CLIMB WELL INTO THE MIDDLE TO UPPER
80S EACH AFTERNOON WITH A FEW LOW 90S NOT OUT OF THE QUESTION.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
5 PM SUN UPDATE... WPC/NWP CONSENSUS SHOWS A FLAT ERN CONUS UPR RIDGE...
GRADUALLY TRANSITIONING TWDS A TROUGH AXIS THROUGH THE OH VLY WITH
TIME. THUS...WE'LL CONTINUE WITH DAILY CHCS FOR SHRA/TSRA...AS A
MOIST SW FLOW ALOFT PREVAILS...ALG WITH FREQUENT PASSAGES OF UPR-
LVL WAVES AND SFC BNDRYS THROUGH THE PD.

TEMPS SHOULD AVERAGE CLOSE TO SEASONAL NORMS FOR LATE JUNE (HIGHS
FROM THE MID 70S-MID 80S).

PREV DISC... A FLAT RIDGE WILL EXIST OVER MUCH OF THE EASTERN
CONUS THIS PERIOD. IMPULSES WILL ROTATE OVER THE TOP OF THE RIDGE,
WHILE WARM/MOIST AIR WILL REMAIN IN PLACE ACROSS NY/PA TYPIFIED BY
850MB TEMPS OF 16C TO 20C.

THE RESULT WILL BE A MILD TEMPERATURE PATTERN, WITH THE DAILY
THREAT FOR ISOLATED TO SCATTERED THUNDERSTORMS. THE BEST CHANCE
FOR THUNDERSTORMS WILL BE ON THURSDAY, WHEN A TROF OVER SOUTHERN
CANADA DIPS ACROSS THE GREAT LAKES TOWARD LAKE ONTARIO.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...

CONV WILL CONT TO WEAKEN THIS EVE BUT LGT FOG AND AND HAZE WILL
LIKELY CONT FOR MUCH OF THE NGT WITH THE LEFTOVER MOISTURE. FOG
MAY RESULT SOME BRIEF IFR VSBYS AT ELM LATE AT NGT. FOR
MON...MIXING IN THE MRNG WILL QUICKLY BURN OFF THE FOG LVG VFR CIGS
AND VSBYS THRU THE DAY. SOME LATE DAY CONV SEEMS LIKELY BUT HAVE
ELECTED TO LEAVE THEM OUT OF THE TAF FOR NOW. ONCE BETTER LOCATION
AND TIMING INFO IS DVLPD THEY LIKELY BE ADDED TO THE FCST.

OUTLOOK...TUE THROUGH FRI...

RESTRICTIONS ARE PSBL EACH DAY...MAINLY IN THE AFTN/EVE...WITH AT
LEAST SCTD SHRA/TSRA FORESEEN. PATCHES OF OVERNIGHT/EARLY AM LOW
