Area forecast discussion, Jul 10, 1:26 PM EDT, 1 hour 24 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
126 PM EDT WED JUL 10 2013

.SYNOPSIS...
WATCH FOR SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
DEVELOPING ACROSS MUCH OF THE NORTH COUNTRY THIS AFTERNOON AND
EVENING. ANY STORMS WILL HAVE THE POTENTIAL TO PRODUCE GUSTY
WINDS AND VERY HEAVY RAINFALL THAT COULD LEAD TO FLASH FLOODING.
THUS A FLASH FLOOD WATCH REMAINS IN EFFECT THIS AFTERNOON THROUGH
MIDNIGHT. THE THREAT FOR PRECIPITATION WILL BE LIMITED TO EASTERN
VERMONT ON THURSDAY AND THEN DRY WEATHER WITH SEASONAL
TEMPERATURES IS EXPECTED FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 1009 AM EDT WEDNESDAY...UPDATE TO POPS THROUGH THE DAY BASED
OFF CURRENT RADAR ACTIVITY AND BLEND OF AVAILABLE CAM MODEL
OUTPUT. STILL LOOKING MORE OR LESS AT 40/70% POPS ACROSS THE AREA
TODAY...BUT DETAILED CURRENT BAND PROGRESSING EAST ACROSS CENTRAL
NY MOVING INTO THE AREA A TAD BETTER AND AS RESOLVED QUITE WELL BY
LATEST HRRR DATA. REST OF FORECAST REMAINS MORE OR LESS IN GOOD
SHAPE. HAVE A GREAT DAY. PRIOR DISCUSSION FOLLOWS...

GOING FORECAST IN GOOD SHAPE AND NO CHANGES NEEDED AT THIS TIME.
THREAT FOR FLASH FLOODING AND STRONG GUSTY WINDS WILL REMAIN
ACROSS MUCH OF THE AREA THIS AFTERNOON AND EVENING. COMPOSITE
ANALYSIS SHOWS STRONGEST DYNAMIC SUPPORT AND DEEP LAYER SHEAR WILL
REMAIN ACROSS EASTERN CANADA THIS AFTERNOON AND EVENING AS LARGE
UPPER TROUGH MOVES INTO THE AREA. LATER THIS AFTERNOON
HOWEVER...THE SOUTHERN END OF THE STRONGER FLOW ALOFT...25 KNOTS
AT 850 MB AND 30 KNOTS AT 500 MB WILL MOVE ACROSS THE SOUTHERN
HALF OF VERMONT THIS AFTERNOON. THIS COMBINED WITH CONVECTIVE
AVAILABLE POTENTIAL ENERGY APPROACHING 1000 J/KG SUGGEST SOME
ORGANIZATION TO THE STORMS WILL EXIST. THUS LOOKING AT
PULSE/MULTICELL STORMS LATER THIS AFTERNOON AND EVENING WITH THE
AREA FROM THE NORTHERN ADIRONDACKS EASTWARD TO THE CONNECTICUT
RIVER VALLEY AS THE MAIN AREA OF CONCERN. AXIS OF HIGH
PRECIPITABLE WATER AIR...VALUES AROUND 2 INCHES...WILL NOSE RIGHT
UP INTO THE AREA. SO WITH STORM MOTIONS UNDER 15 KNOTS...THE
THREAT FOR HEAVY DOWNPOURS AND FLASH FLOODING WILL EXIST
ESPECIALLY SINCE THE AREA COVERAGE OF STORMS WILL BE GREATER THAN
THE PAST COUPLE OF DAYS. THUS GOING IDEA OF A FLASH FLOOD WATCH
FOR MOST OF THE AREA STILL LOOKS GOOD. IN ADDITION...FEEL WITH
SOME ORGANIZATION TO THE STORMS...THREAT FOR STRONG GUSTY WINDS
WILL EXIST. HAVE INCLUDED THE ENHANCED WORDING IN THE FORECAST FOR
THESE TWO THREATS. WE MAY SEE CLOUDS AND SPOTTY SHOWERS MOVE
ACROSS THE AREA THIS MORNING...BUT MAIN THREAT FOR STORMS WILL BE
AFTER 200 PM.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH FRIDAY/...
AS OF 437 AM EDT WEDNESDAY...ACTIVE WEATHER WITH STORMS
POTENTIALLY PRODUCING FLASH FLOODING WILL EXIST THROUGH MIDNIGHT
TONIGHT...THEN INTENSITY OF STORMS WILL WEAKEN OVERNIGHT AND MOVE
EAST OF THE AREA. COLD FRONT WILL BECOME PARALLEL TO THE UPPER
FLOW ON THURSDAY AND THUS THE FRONT WILL STILL HANG AROUND
EASTERN VERMONT FOR A CONTINUED CHANCE OF SHOWERS OR STORMS. HIGH
PRESSURE BUILDS IN LATE THURSDAY NIGHT AND FRIDAY FOR DRIER
WEATHER AND TEMPERATURES TRENDING SLIGHTLY BELOW NORMAL BY
FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 437 AM EDT WEDNESDAY...THE PATTERN CHANGE TO A WESTERLY
FLOW OF DRIER WEATHER WILL PERSIST FRIDAY NIGHT THRU TUESDAY WITH
A WARMING TREND. HIGH PRESSURE WILL PERSIST THROUGH THE WEEKEND
INTO EARLY NEXT WEEK WITH UPPER LEVEL RIDGING AND A NW TO W FLOW
ALOFT. DO NOT SEE ANY SIGNIFICANT CHANCE FOR PRECIPITATION IN THE
EXTENDED. STILL LOTS OF UNCERTAINTY THAT FAR OUT...BUT GFS AND
NAM BOTH HINT AT SOME SHOWERS AROUND FRIDAY NIGHT AND SATURDAY.
HAVE LEANED TOWARDS DRIER ECMWF AT THIS POINT. TEMPERATURES WILL
START OUT SLIGHTLY BELOW NORMAL...BUT TREND BACK OVER NORMAL
TOWARDS THE END OF THE PERIOD.

&&

.AVIATION /17Z WEDNESDAY THROUGH MONDAY/...
THROUGH 18Z THURSDAY...ACTIVE AVIATION FORECAST FOR THIS TAF
ISSUANCE. CURRENT FLIGHT CATEGORIES RANGE FROM VFR TO MVFR. PRE-
FRONTAL LINE OF SHOWERS WITH A FEW EMBEDDED THUNDERSTORMS
EXTENDING DOWN THE CHAMPLAIN TO THE HUDSON VALLEYS WILL CONTINUE
TO PUSH EASTWARD OVER THE NEXT HOUR OR SO PRODUCING TEMPO MVFR/IFR
VISIBILITIES. THINK THE BEST CHANCE AT SEEING ANY THUNDER OUT OF
THIS INITIAL ACTIVITY IS AT RUT WHERE BETTER INSTABILITY EXISTS.
RE- DEVELOPMENT IS EXPECTED ONCE THE INITIAL SHOWERS CLEAR OUT
TIED TO THE COLD FRONT ITSELF...SOME OF WHICH COULD BE STRONG WITH
GUSTY WINDS AND POTENTIAL LLWS/TURBULENCE. HAVE TREATED WITH VCSH
AND CB FOR ALL TAFS EXCEPT MPV TO COVER THIS POTENTIAL MAINLY
AFTER 21Z. FRONT SWEEPS EAST LATE TONIGHT/OVERNIGHT WITH SHARP
WIND SHIFT TO NORTHWEST WITH DECREASE IN SHOWERS/STORMS. THE
EXCEPTION IS AT MPV AND RUT WHERE THE FRONT MAY SLOW. THINK THE
BEST CHANCE AT FOG OVERNIGHT WOULD BE AT SLK AND MSS. SHOWERS
LINGER INTO THE MORNING HOURS ESPECIALLY AT RUT AND MPV BUT
IMPROVING CONDITIONS FOR THE REST OF THE TAFS. WINDS THURSDAY WILL
TEND LIGHT WESTERLY.

OUTLOOK 18Z THURSDAY THROUGH SUNDAY...
18Z THURSDAY THRU 12Z FRIDAY...FRONT SLOWLY SHIFTS SOUTH WITH
SHOWERS ENDING AT MPV AND RUT. MAINLY VFR EXCEPT IFR/LIFR IN
MIST/FOG OVERNIGHT.

12Z FRIDAY THRU SUNDAY...MAINLY VFR EXCEPT MVFR IN PERIODS OF
SHOWERS MAINLY ACROSS RUT WITH SLOW-MOVING FRONTAL BOUNDARY.
OVERNIGHT FOG/MIST POTENTIAL 06-12Z TIMEFRAME ESPECIALLY AT SLK
AND MPV.

&&

.HYDROLOGY...
AS OF 437 AM EDT WEDNESDAY...ONCE AGAIN WE SAW ISOLATED STORMS
PRODUCE FLASH FLOODING ON TUESDAY. CONDITIONS FOR MORE FLASH
FLOODING WILL EXIST THIS AFTERNOON AND EVENING AND THE POTENTIAL
FOR FLASH FLOODING MAY ACTUALLY BE GREATER SIMPLY FOR THE FACT
THAT THERE WILL BE MORE STORMS AROUND THAN THE PAST COUPLE OF
DAYS. EXPECT SCATTERED TO NUMEROUS THUNDERSTORMS DEVELOPING OVER
THE AREA THIS AFTERNOON...ESPECIALLY FROM THE NORTHERN
ADIRONDACKS EASTWARD TO THE CONNECTICUT RIVER VALLEY. THE DEEP
LAYER OF MOISTURE IN THE ATMOSPHERE OVER THE REGION COMBINED WITH
SLOW MOVING STORMS SUGGESTS FLASH FLOODING IS POSSIBLE. THUS WILL
KEEP THE FLASH FLOOD WATCH IN PLACE. POTENTIAL IMPACTS INCLUDE
WASHED OUT AND FLOODED ROADS...FIELD FLOODING...RAPID RISES ON
SMALLER RIVERS AND STREAMS.

&&

.MARINE...
AS OF 436 AM EDT WEDNESDAY...ACTIVE WEATHER IS EXPECTED ACROSS
LAKE CHAMPLAIN TODAY THROUGH THIS EVENING. FIRST EXPECT STRONGER
WINDS OVER THE LAKE WITH SOUTH WINDS INCREASING INTO THE 20 TO 30
KNOT RANGE BY AFTERNOON AND NOT DECREASING UNTIL AFTER MIDNIGHT
TONIGHT. THESE WINDS ARE STRONGER THAN WHAT HAS BEEN FELT OVER
THE LAKE THE PAST FEW DAYS. THUS A LAKE WIND ADVISORY IS IN
EFFECT. IN ADDITION...EXPECT THUNDERSTORMS TO DEVELOP OVER
NORTHERN NEW YORK THIS AFTERNOON AND MOVE EAST ACROSS LAKE
CHAMPLAIN. BE AWARE THAT ANY STORMS WILL HAVE THE POTENTIAL TO
PRODUCE STRONG GUSTY WINDS AND AS WE HAVE SEEN THE PAST MONTH OR
SO...VERY HEAVY DOWNPOURS.

&&

.EQUIPMENT...
AS OF 436 AM EDT WEDNESDAY...THE KTYX RADAR IS DOWN UNTIL FURTHER
NOTICE. TECHS HAVE ORDERED PARTS...THOUGH RETURN TO SERVICE IS
UNKNOWN AT THIS TIME.
