AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
117 PM EDT WED JUN 1 2011
.SYNOPSIS...
ACTIVE WEATHER IS EXPECTED ACROSS THE NORTH COUNTRY TODAY. A
FRONT WILL MOVE INTO VERMONT BY MIDDAY AND STRONG TO POSSIBLY
SEVERE STORMS WILL DEVELOP AHEAD OF IT AND EXIT THE REGION BY
LATE AFTERNOON. AT THE SAME TIME...STRONG AND GUSTY SOUTHWEST
WINDS WILL DEVELOP BEHIND THE FRONT IN NORTHERN NEW YORK WITH
WIND GUSTS UP TO 50 MPH EXPECTED.
&&
.NEAR TERM /UNTIL 10 PM THIS EVENING/...
AS OF 117 PM EDT WEDNESDAY...ONLY MINOR TWEAKS TO T/TD DATA AS OF
1 PM...PRIMARILY TO MATCH CURRENT OBSERVATIONS. SVR WATCH #410
CONTINUES UNTIL 5 PM...THOUGH BEST THREAT FOR SVR WILL EXIST
ACROSS CENTRAL/SRN VT...WITH THREAT DIMINISHING FURTHER NORTH AND
WEST. WILL RE-ASSESS WATCH STATUS BY NEXT UPDATE TIME AT 4-430 PM.

PRIOR DISCUSSION...
QUICK UPDATE THIS MORNING...PRIMARILY TO HOIST SVR T-STORM WATCH
#410 AND MASSAGE POPS THROUGH THE DAYLIGHT HOURS BASED OFF CURRENT
AND EXPECTED SHOWER/STORM ACTIVITY TODAY. I'VE ALSO RAISED MAX
TEMPERATURES BASED OFF NEW GUIDANCE AND MODEL MIXING/925 MB
THERMAL PROGS. LATEST ANALYSIS SHOWING PRE- FRONTAL TROUGH AND
ASSOC THUNDERSTORM ACTIVITY WHICH BROUGHT LOCALLY TORRENTIAL
DOWNPOURS AND SCATTERED DAMAGE TO THE AREA EARLIER THIS MORNING
NOW WELL EAST OF VERMONT PUSHING ACROSS MAINE SOUTH INTO THE
OFFSHORE SRN NEW ENGLAND WATERS. SFC FRONT NOW PUSHING ACROSS NRN
NY AND THIS WILL BE THE FOCUS FOR ADDITIONAL SCATTERED STRONG TO
LOCALLY SEVERE STORMS THIS AFTERNOON...MAINLY ACROSS OUR CENTRAL
AND SOUTHERN VERMONT COUNTIES. INSTABILITY/0-6KM SHEAR AND
DYNAMICAL SUPPORT FOR LIFT ALL THERE SO SHOULD BE AN ACTIVE DAY.
LOOKING AT WIND FIELDS PRIMARY SEVERE THREAT WILL BE STRAIGHT LINE
WIND DAMAGE. REST OF FCST UNCHANGED AT THIS TIME.
PRIOR DISCUSSION...
INITIAL AREA OF CONVECTION IS MOVING OUT OF VERMONT AND HAS DONE
NOTHING BUT ADDED MORE MOISTURE TO THE AIR MASS. CLEARING SKIES
WILL DEVELOP AND DESTABILIZATION WILL RESULT IN INCREASED
INSTABILITY...ESPECIALLY ACROSS VERMONT. STORMS SHOULD FORM AROUND
MIDDAY ALONG PRE-FRONTAL TROUGH MOVING INTO WESTERN VERMONT.
IMPRESSIVE DEEP LAYER SHEAR MOVING OVER THE TOP OF THE INSTABILITY
WILL SUPPORT ORGANIZED STORMS AND SOME OF THEM WILL BECOME STRONG
TO SEVERE THIS AFTERNOON. BEHIND THE PRE- FRONTAL TROUGH DEEP
MIXING WILL ALLOW STRONG WINDS ALOFT TO MIX DOWN AND WIND ADVISORY
FOR MUCH OF NORTHERN NEW YORK STILL LOOKS GOOD FOR WIND GUSTS TO
50 MPH.
&&
.SHORT TERM /10 PM THIS EVENING THROUGH FRIDAY NIGHT/...
AS OF 541 AM EDT WEDNESDAY...FLOW ALOFT WILL BECOME MORE
NORTHWEST WITH TIME TONIGHT WITH GUSTY WINDS CONTINUING OVER THE
ENTIRE FORECAST AREA...40 MPH OVER VERMONT AND AROUND 50 MPH IN
NORTHERN NEW YORK. LARGE UPPER TROUGH MOVES ACROSS EASTERN CANADA
ON THURSDAY AND EXPECT INSTABILITY CLOUDS AND SHOWERS TO DEVELOP
OVER THE AREA...ESPECIALLY IN THE MOUNTAINS. NOTICEABLY COOLER
WEATHER IS EXPECTED AS WELL GIVEN STRONG COLD AIR ADVECTION.
EXPECTING HIGHS ONLY IN THE 60S ON THURSDAY. HIGH PRESSURE BUILDS
IN THURSDAY NIGHT AND FRIDAY ALLOWING FOR DRIER WEATHER AND A
SLOW WARMING TREND. HIGH TEMPERATURES ON FRIDAY SHOULD BE CLOSE
TO SEASONAL NORMALS. ONE OTHER ITEM OF NOTE WILL BE THE NEED TO
MONITOR THE FROST POTENTIAL ACROSS THE NORTHERN ADIRONDACKS AND
NORTHEAST VERMONT THURSDAY NIGHT.
&&
.LONG TERM /SATURDAY THROUGH TUESDAY/...
AS OF 930 AM EDT WEDNESDAY...UPDATED THE EXTENDED GRIDS THIS
MORNING TO FRESHEN UP THE DATA. NOT A WHOLE LOT GOING ON IN THE
EXTENDED PORTION OF THE FORECAST. GENERAL SURFACE HIGH PRESSURE
WILL BE IN PLACE FOR THE ENTIRE PERIOD. AN UPPER LEVEL RIDGE
BUILDS INTO THE NORTH COUNTRY FOR SATURDAY...THEN NORTHWEST FLOW
DEVELOPS BEHIND IT AND REMAINING THROUGH THE END OF THE EXTENDED.
DRIER WEATHER WITH NEAR NORMAL SEASONAL TEMPERATURES ARE EXPECTED
FROM FRIDAY NIGHT THROUGH TUESDAY. AS NORTHWEST UPPER LEVEL FLOW
DEVELOPS THERE WILL BE MORE CHANCES FOR PRECIPITATION WITH
SHORTWAVES PASSING THROUGH PROGRESSIVE UPPER LEVEL FLOW.
