What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Burlington, VT wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 17, 7:46 PM EDT, 5 minutes earlier.

Area forecast discussion, Jul 17, 7:46 PM EDT, 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
746 PM EDT TUE JUL 17 2012

.SYNOPSIS...
ANY THUNDERSTORMS DURING THE EVENING WILL COME TO AN END BY
MIDNIGHT AS A SLOW MOVING COLD FRONT MOVES THROUGH THE REGION LATE
TONIGHT AND ON WEDNESDAY. BEHIND THE FRONT, IT WILL TURN COOLER
AND DRIER AND THAT WILL LAST INTO THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
AS OF 741 PM EDT TUESDAY...COMPLEX OF SEVERE T-STORMS HAS PUSHED
PRIMARILY SOUTH OF THE FORECAST AREA, AND SO HAVE JUST CANCELLED
THE SEVERE T-STORM WATCH FOR MOST OF THE AREA. HAVE KEPT IT UP FOR
RUTLAND AND WINDSOR COUNTIES JUST IN CASE THEY GET CLIPPED BY SOME
STORMS THAT ARE OUT IN NORTH-CENTRAL NEW YORK AS THEY TREK
SOUTHEASTWARD. THOUGH NOT ALL THAT CONFIDENT WE'LL SEE MUCH.

STILL HAVE A FEW SHOWERS AND ISOLATED THUNDERSTORMS ACROSS
NORTHERN NEW YORK THAT ARE PUSHING INTO NORTHERN VERMONT AS A
RESULT OF SOME RESIDUAL INSTABILITY. DO NOT EXPECT ANY OF THEM TO BE
SEVERE, AND JUST PROVIDE A QUICK DOWNPOUR.

THINK JUST ABOUT EVERYTHING SHOULD BE DONE WITH BY MIDNIGHT --
EITHER DISSIPATED OR PUSHED WELL TO THE SOUTH.

PRETTY WILD DAY ON THE RADAR, WITH SEVERAL LONG LIVED SUPERCELLS
THAT PUSHED ACROSS THE AREA, THOUGH A COUPLE OF THE BEST ONES ON
RADAR STAYED NORTH OF THE BORDER. REPORTS SO FAR ARE PRIMARILY DUE
TO STRAIGHT LINE WINDS, WITH A FEW HAIL REPORTS TOSSED IN FOR GOOD MEASURE.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
AS OF 350 PM EDT TUESDAY...WEDNESDAY WILL BE A TRANSITION DAY AS
THE FRONT SLOWLY OOZES THROUGH THE REGION. MAY BE A LIGHT SHOWER
WAY DOWN SOUTH, SO CONTINUED THE IDEA OF LOW CHANCES THERE.
OTHERWISE IT SHOULD BE A GENERALLY SUNNY DAY WITH DEWPOINTS SLOWLY
FALLING DURING THE DAY. 850MB TEMPERATURES WILL RANGE FROM 12C IN
THE NORTH TO 15C DOWN SOUTH, SO WE ARE STILL LOOKING AT
TEMPERATURES PRIMARILY IN THE 80S, MAYBE CLOSE TO 90F DOWN IN
SPRINGFIELD. AT LEAST THE DEWPOINTS WILL BE ON THE DECREASE,
FALLING INTO THE 50S BY THE AFTERNOON.

HIGH PRESSURE WILL BE NOSING IN WEDNESDAY NIGHT AND THURSDAY, SO
PRETTY MUCH HIGH AND DRY. 850 TEMPERATURES WILL BE FALLING TO THE
8-12C LEVEL, SO HIGHS ONLY IN THE 70S ON THURSDAY. TEMPERATURES
THURSDAY NIGHT WILL FALL INTO THE 50S WITH 40S IN THE COOLER
AREAS, SO IT MIGHT BE A GREAT NIGHT TO OPEN THE WINDOWS AND PUT ON
A COUPLE OF BLANKETS. STAYED CLOSED TO GUIDANCE TEMPERATURES.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
AS OF 319 PM EDT TUESDAY...NORTHWEST FLOW ALOFT AND SURFACE HIGH
PRESSURE WITH ORIGINS OVER CENTRAL CANADA WILL BE IN PLACE OVER
THE NORTH COUNTRY INTO SATURDAY WITH A NICE STRETCH OF DRY
WEATHER. AS THE HIGH SLIDES EAST ON SUNDAY ANOTHER COLD FRONT AND
UPPER TROUGH DROPS SE WITH A CHANCE OF SHOWERS AND THUNDERSTORMS.
LOOKS LIKE WARMTH AND INSTABILITY/0-6KM SHEAR (1500 J/KG/ 35KT)
MAY BE SUFFICIENT FOR ANOTHER ROUND OF POTENTIALLY STRONG TO
SEVERE STORMS. THE FRONT PUSHES SOUTH ALLOWING FOR A NORTHERLY
FLOW COOLER AND DRIER WEATHER AS ANOTHER HIGH DROPS OUT OF CENTRAL
CANADA. HIGH TEMPERATURES WILL BE IN THE 80S FRIDAY THROUGH SUNDAY
DROPPING BACK INTO THE 70S BY MONDAY AND TUESDAY. LOWS WILL BE
MOSTLY IN THE 50S EXCEPT A FEW 40S IN THE COLD SPOTS SATURDAY AND
TUESDAY MORNINGS. AREAS NEAR LAKE CHAMPLAIN WILL BE MILDER WITH
WATER TEMPS NOW IN THE MID 70S.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
THROUGH 00Z THURSDAY...SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS WILL MOVE FROM WEST TO EAST ACROSS THE AREA THROUGH
06Z TONIGHT. THIS WILL RESULT IN MVFR CONDITIONS FROM TIME TO
TIME. AFTER 06Z...THE SHOWERS AND STORMS WILL DIMINISH AND
CEILINGS AND VISIBILITIES WILL LOWER INTO THE MVFR AND IFR
CATEGORIES FOR SOME PERIODS OF TIME. AFTER 14Z...LOOK FOR VFR
CONDITIONS TO DEVELOP OVER THE ENTIRE AREA AND REMAIN IN THE VFR
CATEGORY THROUGH THE END OF THE PERIOD.

OUTLOOK 00Z THURSDAY THROUGH SUNDAY...MAINLY VFR THROUGH THE
PERIOD WITH HIGH PRESSURE BUILDING INTO THE REGION. PSBL VLIFR IN
FG KMPV KSLK 07-12Z EACH MORNING.

.EQUIPMENT...
IMPORTANT RADAR UPGRADES ARE IN PROGRESS...

THE WSR-88D IN FORT DRUM NEW YORK (KTYX) IS OPERATING WITH DUAL
POLARIZATION TECHNOLOGY.

THE WSR-88D IN COLCHESTER VERMONT (KCXX) IS SCHEDULED NEXT FOR ITS
