Area forecast discussion, Jun 23, 1:55 PM EDT, 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
155 PM EDT TUE JUN 23 2015

.SYNOPSIS...
SHOWERS AND THUNDERSTORMS ARE LIKELY TODAY, AS A STRONG LOW
PRESSURE SYSTEM MOVES THROUGH EASTERN CANADA. THIS SYSTEM WILL
PUSH A WARM FRONT THROUGH THE AREA, FOLLOWED BY A TRAILING COLD
FRONT TODAY. SOME OF THE THUNDERSTORMS COULD HAVE DAMAGING WINDS
AND HEAVY RAIN. MOSTLY SUNNY SKIES AND PLEASANT TEMPERATURES WILL
RETURN ON WEDNESDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
0945 AM UPDATE...
THE INITIAL LINE OF SHOWERS AND STORMS HAS RACED THROUGH AND
WEAKENED AS IT DID SO WITH ONLY A HANDFUL OF REPORTS OF WIND
DAMAGE OVER STEUBEN INTO CHEMUNG COUNTIES. THE WATCH HAS BEEN
DROPPED. SOME SHOWERS/STORMS STILL OVER NE PA INTO
DELAWARE/SULLIVAN COUNTIES BUT THESE WILL EXIT WITHIN THE NEXT
HOUR OR TWO. BEYOND THIS TIME QUESTION IS HOW MUCH THE ATMOSPHERE
CAN RECOVER BEFORE THE MAIN FRONT COMES THROUGH THIS AFTERNOON. AT
THIS POINT THREAT OF SEVERE WEATHER FOR THIS AFTERNOON APPEARS TO
BE MAINLY FROM AROUND BROOME COUNTY EASTWARD THEN SOUTHWARD INTO
NE PA AS THE FRONT WILL BE CLEARING AREAS FARTHER WEST. STILL,
CONVECTION WILL LIKELY BE MORE SCATTERED IN NATURE SO DON'T SEE A
HIGH PROBABILITY OF WIDESPREAD SEVERE WEATHER. UPDATES WERE MADE
TO POP/WEATHER GRIDS TO REFLECT THIS LATEST THINKING.

TONIGHT CLEARING SKIES AS TEMPS AND DEWPTS DROP INTO THE 50S.
STRONG BOUNDARY LAYER WINDS SO DO NOT EXPECT VALLEY FOG.

HIGH PRESSURE FROM THE OHIO VALLEY BUILDS IN WED TO BE OVER THE
REGION WED NGT. DRY SEASONABLE AIR.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
115 PM EDT UPDATE...
WED NIGHT IS EXPECTED TO BE DRY AS HIGH PRESSURE RESIDES OVER
THE REGION. BY THURS MORNING WE TRANSITION INTO A PATTERN WHERE WE
HAVE TROUGHING IN THE EAST AND RIDGING IN THE WEST. THIS WILL
ALLOW FOR A CHANCE FOR PRECIP OVER OUR AREA STARTING THURS AND
LASTING THRU THE PERIOD. A LOW PRESSURE SYSTEM WILL DRIFT ACROSS
THE MID WEST THEN OVER SOUTHERN PA THURS... WHICH MAY BRING
SHOWERS OVER THE CWA STARTING THURS MORNING. THE CHANCE FOR RAIN
SHOWERS WILL INCREASE DURING LATE AFTERNOON AND WILL REMAIN
THROUGH THE PERIOD. THIS PATTERN ALLOWS MULT WAVES TO MOVE
BRINGING MORE CHANCES FOR RAIN.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
115 PM EDT UPDATE...
CLOSELY FOLLOWED WPC GUIDANCE.

A VERY ACTIVE PATTERN CONTINUES AND WILL REMAIN IN PLACE THRU THE
END OF THE FORECAST PERIOD. THIS PATTERN CONSISTS OF TROUGHING OVER
THE EAST AND RIDGING OVER THE WEST. KEPT A CHANCE FOR PRECIP OVER
THE CWA THRU THE WHOLE PERIOD. MULT WAVES WILL RIDE AROUND THE
TROUGH AND CREATE ENOUGH UPPR LVL SUPPORT FOR SHOWERS. THIS PATTERN
WILL ALSO CREATE CLOUDY SKIES ALONG WITH BELOW NORMAL TEMPS FOR THIS
TIME OF YR.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
WE STILL HAVE THE CHANCE FOR SOME SHOWERS AND STORMS THIS
AFTERNOON AHEAD OF A COLD FRONT WITH THE BEST CHANCES BEING FOR
KAVP. CONFIDENCE AND COVERAGE IS NOT HIGH ENOUGH TO WARRANT
INCLUSION IN THE TAFS FOR THE REMAINDER OF THE SITES. MVFR AND
EVEN BRIEF IFR WILL BE POSSIBLE IN ANY SHOWERS OR STORMS THAT
OCCUR ALONG WITH GUSTY WINDS. CONDITIONS QUICKLY CLEAR BEHIND THE
FRONT THIS EVENING WITH RESTRICTION FREE CONDITIONS FOR THE
REMAINDER OF THE TAF PERIOD. THE EXCEPTION IS KELM WHICH MAY SEE
SOME MIST OR FOG OVERNIGHT.

STRONG GUSTY W/SW WINDS THIS AFTERNOON TURN NW BEHIND THE FRONT
AND DIMINISH THIS EVENING.
