AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
158 PM EDT TUE MAY 19 2015

.SYNOPSIS...
SHOWERS WILL SLOWLY EXIT THE REGION TO THE EAST THIS MORNING
FOLLOWED BY A BRIEF BREAK IN THE PRECIPITATION. LATER THIS
AFTERNOON THUNDERSTORMS ARE EXPECTED TO FORM OVER THE CHAMPLAIN
VALLEY AND MOVE EAST THROUGH EARLY EVENING. ANY OF THESE STORMS
WILL HAVE THE POTENTIAL TO PRODUCE GUSTY WINDS AND SMALL HAIL.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 132 PM EDT TUESDAY...RADAR TRENDS SHOW A LINE OF SHOWERS
HAVE DEVELOPED ALONG A BOUNDARY OF INSTABILITY OVER NORTHERN NEW
YORK. THE CLEARING SKIES HAVE ALLOW TEMPS ACROSS MUCH OF THE AREA
TO WARM TO THE MID 70S UNDER THE MODERATE SOUTHERLY FLOW. THE
EXCEPTION IS NEAR THE BROAD LAKE AND JUST TO THE WEST OF LAKE
CHAMPLAIN AS A SLIGHT EASTERLY COMPONENT TO THE WINDS IS KEEPING
THE WESTERN EDGE OF THE CHAMPLAIN VALLEY IN THE MID 60S. THE LINE
OF STORMS OVER NORTHERN NEW YORK ARE BEGINNING TO BUILD WITH
HEIGHT AND SO I EXPECT THIS AFTERNOON WILL STILL LIKELY SEE AND
GOOD CHANCE FOR SOME STRONG STORMS TO DEVELOP OVER THE NORTH
COUNTRY FROM THE ADIRONDACKS EASTWARD. THE MAIN THREATS WILL BE
SOME GUSTY WINDS WITH SMALL HAIL. THE BEST INSTABILITY WILL STILL
BE ALONG A NARROW AXIS WHERE THE SKIES HAVE SCATTERED OUT AHEAD OF
THE COLD FRONT. ONCE THE COLD FRONT MOVES INTO THE AREA ANY AND
ALL CONVECTION WILL DROP DRAMATICALLY AS THE MOISTURE SOURCE AND
INSTABILITY WILL WEAKEN QUICKLY.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH THURSDAY/...
AS OF 421 AM EDT TUESDAY...THE SHOWERS AND STORMS COME TO AN END
BY 800 PM WITH JUST SOME SHOWERS POSSIBLE LATER TONIGHT OVER THE
MOUNTAINS AS A WEAK DISTURBANCE MOVES ACROSS THE REGION. WEST TO
NORTHWEST FLOW ALOFT BECOMES ESTABLISHED OVER THE AREA WEDNESDAY
INTO THURSDAY...WHICH WILL ALLOW FOR DRIER AIR TO RETURN ALONG
WITH BELOW NORMAL TEMPERATURES BOTH DAYS. HIGHS WILL GENERALLY BE
IN THE 60S DURING THIS TIME PERIOD.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 132 PM EDT TUESDAY...THE GENERAL IDEA FOR THE EXTENDED HAS
BEEN PRETTY CONSISTENT OVER THE PREVIOUS 3-4 MODEL CYCLES FOR THE
END OF THE WEEK. A BROAD UPPER LEVEL TROUGH CENTERED OVER QUEBEC
WILL SLOWLY DRIFT EAST AND A PERSISTENT SURFACE RIDGE WILL BRING
QUIET WEATHER THROUGH THE WEEKEND WITH SEASONABLY COOL
TEMPERATURES. FRIDAY DURING THE DAY THERE WILL BE A SLIGHT CHANCE
FOR SOME SHOWERS TO DEVELOP AS WE WILL BE UNDER NORTHWEST FLOW AND
A BRIEF BURST OF SHORTWAVE ENERGY WILL DROP DOWN ALONG THE
INTERNATIONAL BORDER. THE COMBINATION OF MARGINALLY ENHANCED
VORTICITY AND NORTHWEST UPSLOPE FLOW SHOULD BE ENOUGH TO BRING
MEASURABLE PRECIP TO THE AREA MAINLY IN THE FAVOURED UPSLOPE
REGIONS. THE ONLY LIMITING FACTOR... AND ITS A BIG ONE... WILL BE
THE LACK OF MUCH MOISTURE TO WORK WITH THUS WE WILL LIKELY NEED
THE OROGRAPHIC LIFT TO DEVELOP MUCH IN THE WAY OF SHOWERS. FROM
THERE THE WEEKEND IS DRY AND THE NEXT BEST CHANCE FOR SHOWERS WILL
BE AS A WEAK COLD FRONT FINALLY DROPS OUT OF THE UPPER LEVEL
TROUGH ON LATE SUNDAY EVENING/MONDAY MORNING.

THE ONLY REAL WEATHER CONCERN IN THE EXTENDED WILL BE THE
SEASONABLY COLD TEMPS OVERNIGHT. LOWS ON FRIDAY NIGHT AND WILL SEE
AREA WIDE LOW 30S WITH UPPER 20S POSSIBLE IN THE TYPICALLY COLDER
REGIONS OF THE NORTHEAST KINGDOM AND NORTHERN ADIRONDACKS AS WE
WILL SEE DECENT RADIATIONAL COOLING UNDER CLEAR SKIES AND SOMEWHAT
LIGHT WINDS. IF THE MODELS HOLD IN THIS PATTERN FROST ADVISORIES
AND FREEZE WARNINGS WILL BE LIKELY. HOWEVER AS THE PATTERN CHANGES
INTO THE WEEKEND AND WE GET INTO THE SOUTHERLY RETURN FLOW TEMPS
WILL WARM BACK TOWARDS MORE SEASONABLE 40S ACROSS THE REGION FOR
OVERNIGHT LOWS. MAX TEMPS DURING THE PERIOD WILL WILL BE WARMING
THROUGHOUT WITH LOW 60S ON FRIDAY WARMING TO THE LOW TO MID 70S BY
TUESDAY.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
THROUGH 18Z WEDNESDAY...VFR WITH SHORT-DURATION MVFR/LOCAL IFR
VISBILITY ASSOCIATED WITH DEVELOPING THUNDERSTORMS THIS AFTERNOON.
ASSOCIATED LIGHTNING RISK IN ANY THUNDERSTORM, THOUGH STRONG
THUNDERSTORMS COULD ALSO PRODUCE SMALL HAIL AND OUTFLOW WINDS
PRODUCING LOCALIZED TURBULENCE.

RADAR SCATTERED TO BROKEN LINE OF HEAVY SHOWERS AND THUNDERSTORMS
DEVELOPING NEAR THE ADIRONDACKS ALONG A COLD FRONT. THESE WILL PUSH
EASTWARD AND GENERALLY STRENGTHEN ACROSS MOST OF THE TAFS THROUGH
00Z WEDNESDAY. I'VE SHOWN TEMPO 2-3SM -TSRA AS STORM MOTIONS ARE
PRETTY PROGRESSIVE, AND WILL APPLY AMENDMENTS AS NECESSARY FOR
SPECIFIC OUTFLOW GUSTS. WINDS GRADUALLY SHIFT TO WEST-SOUTHWEST AND
THEN NORTHWEST AROUND 10-12 KTS BY 00Z. LATER IN THE EVENING, LARGE
BKN/OVC DECK NOW EVIDENT IN VISIBLE IMAGERY ACROSS GREAT LAKES WILL
SWEEP ACROSS THE TAFS.

CEILINGS TO THIN OUT INTO WEDNESDAY TO A SCT/BKN CU DECK.
NORTHWEST WINDS AROUND 10 KTS WITH GUSTS TO 20-25 KTS DEVELOPING
AS STRONGER MIXING TAKES PLACE.

OUTLOOK 18Z WEDNESDAY THROUGH SUNDAY...

18Z WEDNESDAY - 00Z THURSDAY...MAINLY VFR WITH GUSTY NORTHWEST
WINDS AND ISOLATED SHOWERS.

00Z THURSDAY - 00Z FRIDAY...VFR UNDER HIGH PRESSURE.

00Z FRIDAY - 00Z SATURDAY...MAINLY VFR WITH BRIEF MVFR RAIN
SHOWERS POSSIBLE.

00Z SATURDAY - 12Z SUNDAY...VFR UNDER HIGH PRESSURE.

SUNDAY...MAINLY VFR THOUGH A COLD FRONT MAY TRIGGER SHOWERS ACROSS
NORTHERN TAFS.

&&

.MARINE...
AS OF 943 AM EDT TUESDAY...BOTH A A LAKE WIND ADVISORY AND A LAKE
THUNDERSTORM ADVISORY ARE NOW IN EFFECT FOR LAKE CHAMPLAIN.
RECENT COLCHESTER REEF AND DIAMOND ISLAND OBSERVATIONS INDICATE
THAT SOUTHERLY WINDS HAVE INCREASED INTO THE 15 TO 25 KT RANGE AND
WILL REMAIN SO INTO THE AFTERNOON HOURS. WAVES OF 1 TO 3 FEET ARE
EXPECTED, HIGHEST IN SOUTH-FACING EXPOSURES.

BOATERS AND OTHER RECREATIONAL INTERESTS ON LAKE CHAMPLAIN SHOULD
BE AWARE THERE IS A LINE OF SHOWERS PRODUCING OCCASIONAL THUNDER
MOVING TOWARDS THE LAKE. THESE SHOWERS MAY BECOME STRONG PRODUCING
GUSTY WINDS AND SMALL HAIL, AS WELL AS FREQUENT LIGHTNING.
