Whats the record for shortest thread?

Some good technical info from BTV. I highlighted the snow talk.

http://www.crh.noaa.gov/product.php?site=N...p;highlight=off

"QPF FIELDS OFF THE GFS/NAM BOTH SHOW OVER 1.0" POSSIBLE NEAR JAY PEAK TO MANSFIELD...WITH LESS THAN 0.10" AT BTV...SHOWING THE VERY SHARP PRECIP GRADIENT
WHICH IS VERY TYPICAL OF THESE EVENTS. THERMAL PROFILES WL BE
TRICKY...WITH BEST POTENTIAL FOR ACCUMULATING SNOWFALL ON MONDAY NIGHT INTO TUES MORNING ABOVE 1500 FT ACRS THE CENTRAL/NORTHERN GREENS. ON MONDAY...FEEL BL TEMPS WARM BTWN 1 AND 3C...WITH 925MB TEMPS NEAR 2C...WHILE 85H TEMPS STAY BTWN -2C AND -4C...SUPPORTING SNOW LEVELS ABOVE 2500FT.

HOWEVER...THESE TEMPS WL COOL SLIGHTLY ON MONDAY NIGHT WITH NORTHERLY FLW AND THE LOSS OF SFC HEATING FROM THE HIGH SUN ANGLE. MEANWHILE...FAVORABLE DEEP LAYER MOISTURE AND SEVERAL EMBEDDED VORTS WL ROTATE THRU OUR CWA AND ENHANCE SYNOPTIC LIFT...ALONG WITH FAVORABLE UPSLOPE FLW/BLOCKING WL PROVIDE LVLL MESO-SCALE LIFT ACRS OUR MTNS. THIS LLVL COOLING AND LIFT WL RESULT IN DROPPING SNOW LEVELS WITH SOME ACCUMULATION LIKELY BY 12Z TUES....ESPECIALLY ABOVE 1500FT. THINKING A GENERAL 2 TO 5 INCHES WL BE POSSIBLE ACRS THE MTNS...WITH A MIXTURE OF VERY LIGHT RAIN/SNOW SHOWERS POSSIBLE ACRS THE VALLEYS WITH TOTAL QPF <0.10 THRU 12Z TUES."

Very interesting stuff...I had noticed this morning that the low off of the California coast is also slightly retrograding...it seems as if the flow along the US/Canada border is one of those strange motions...
Then I saw the storm pinwheeling back into Maine, and Quebec and realized the whole flow is retro-ing...

Good luck for the folks seeing snow, so far in my area cool and cloudy , will be lucky to see a rain shower at some point.

[blizzardOf96]

About 5-6" of snow here in Moncton, New Brunswick, Canada!!! Winter is back!

[NorEaster07]

http://www.noaawatch.gov/

"Over the Northeast, a strong low moving inland over Nova Scotia on Sunday will slowly back into Quebec and bring light snow down to northern New England. Rain will be the dominate precipitation type farther south, but some snow could mix in along the higher elevations of the northern Appalachians.

A cold front over the Great Lakes and Ohio Valley will sweep to the Atlantic Coast on Sunday.

This boundary, and a second cold front dropping south from Canada Sunday and Monday, will also bring reinforcing shots of cooler, drier air across much of the Northern Plains, Midwest, and northeastern U.S.."

You want technicals? Slowly read BTVs discussion. Good stuff. Always Love the Vertically stacked talk.

BTV

WATER VAPOR AND SFC ANALYSIS SHOWS A SLOW MOVING VERTICALLY
STACKED AREA OF LOW PRES ACRS NORTHERN MAINE...TRACKING TWD NORTHERN VT ATTM.

QPF WL RANGE BTWN A COUPLE HUNDREDTHS VALLEYS TO 0.20 TO 0.40" OR SO FROM SUGARBUSH TO MOUNT MANSFIELD TO JAY PEAK. MEANWHILE...NAM/WRF THERMAL
PROFILES SHOW THE FREEZING LEVEL BTWN 2800FT AND 3000 FT
TODAY...ASSOCIATED WITH WARM BL TEMPS AND PROGGED 925MB TEMPS
AROUND 2C...SO EXPECT SNOW LEVELS ABOVE 2500 FT. HOWEVER...BY
TONIGHT SLIGHTLY COOLER TEMPS ADVECT INTO THE REGION WITH 925MB
TEMPS FALLING TO 0C AND 85H TEMPS BTWN -3C AND -4C. THIS COMBINED
WITH SOUNDINGS SHOWING THE 0C LEVEL DROPPING TO 1800FT...SUPPORTS
LOWERING SNOW LEVELS TO AROUND 1500FT OVERNIGHT. LOCAL WRF AND
NAM 12 CONT TO SHOW FAVORABLE WESTERLY UPSLOPE FLW AND PLENTY OF
LLVL LIFT ALONG THE WESTERN SLOPES/NORTHERN DACKS...ALONG WITH

CLOSED/SLOW MOVING VERTICALLY STACKED AREA OF LOW PRES. THE
RESULT WL BE OCCASIONAL SHOWERS WITH GREATEST QPF/HIGHEST POPS
ACRS THE MTNS ZNS. GIVEN THE CYCLONIC FLW AND PLENTY OF
MOISTURE...EXPECT MTN ZNS TO RECEIVE MEASURABLE PRECIP THRU THE
PERIOD...WITH SOME SNOW ACCUMULATION POSSIBLE AT NIGHT. VERY
LITTLE CHANGE IS ANTICIPATED THRU THE PERIOD AS PLENTY OF
MOISTURE WITH EMBEDDED 5H VORTS ROTATING ACRS OUR CWA AND LLVL
THERMAL PROFILE REMAINS SIMILAR...WITH SOME SLIGHT COOLING TWD
WEDS. EXPECT DAILY HIGH TEMPS IN THE M/U30S MTNS TO M/U40S
VALLEYS WITH A FEW 50S POSSIBLE IF MORE SUN OCCURS THAN
ANTICIPATED. NIGHT-TIME TEMPS WL FALL BACK INTO THE 30S MTNS TO

Saw some snowflakes in the sky yesterday... for about 5 minutes the snowflakes got quite large and were quite visible... neat to see. Then by afternoon we got a steady rain.
