NNE Winter 2012-13 Thread III

Recommended Posts

Maybe 0.1" dusting on "T" precip here.  It was 8F at 7A, now into the teens.  Howeer, at 4A it was -12, probably just before the clouds filled in.  Yesterday's temps 10/-10; might have a day or two with highs zero to +5 next week - heart of winter temps.  However, the past 5 Januarys have all recorded total snowfall between 23.6" and 27.5", and I seriously doubt we'll make it up to that range this year.

Looks like the sfc boundary is finally making its way through here. Temp is up to 26F and rising quickly. It should get into the mid 30s by afternoon.

Around 4 inches here in Peacham, probably a little over but I'll call it 4.  Quite a bit of blowing around.

This morning I hiked Mt Hancock and South Hancock, two more on the NH48 4000' list. I think I'm up to 30 or so on that list. But I digress. The forecast was calling for a few inches of snow and strong winds at the summit, so I was figuring I might give the Kestrel a workout. Snow was falling on the drive over, with maybe a couple inches of new fluff at the trailhead, which is located on the Kanc's hairpin curve. 21° as I started off and no wind. Nice day with light snow falling ... was maybe 4" near the summits, but there was an awful lot of blowing and drifting going on.

I chose the Hancocks because I feared clouds may obscure the views, and the views from these two peaks are limited. Turns out the clouds stayed high and the visibility was pretty good. At the summit of Hancock I measured a temp of 14°, a peak wind gust of 15mph and a wind chill of -2°. Not as brutal as I was expecting but pretty chilly nonetheless when not moving. I also got in some heroic glissading down South Hancock. That was fun! Below are a couple of pics from the trip. Enjoy! :)

Awesome shots... I love how the Whites are more like a clump of mountains (like the Adirondacks) whereas here in VT we have a series of north-south oriented ridges/spines.  When you look out here, you see valley on two sides, and big mountains north/south... there's none of that 360 degree views of more mountains.

Looks like I ended up with 2.2" from this morning's snow at home...maybe 2.5 or so when it ended

but by the time I got home there was just under two and a quarter, with a temp of 34F and it looked settled.

Either way, it was a nice little refresh and hopefully we can tack on another 1-2" tomorrow in the squalls with the arctic front.

.NEAR TERM /THROUGH SUNDAY NIGHT/...

AS OF 322 PM EST SATURDAY...AN ACTIVE WEATHER DAY IS ON TAP FOR

SUNDAY WITH SEVERAL WEATHER CONCERNS...INCLUDING GUSTY WINDS...

SNOW SQUALLS...AND POTENTIAL FOR A FLASH FREEZE.

WARM FRONTAL BOUNDARY HAS NOW CLEARED THE REGION AND LIES ACROSS

SOUTHERN QUEBEC AND ONTARIO. STILL HAVE MOISTURE RIDING ALONG THE

BOUNDARY HOWEVER SO WIDESPREAD CLOUDS ARE EXPECTED FOR OVERNIGHT.

A VERY WEAK DISTURBANCE WILL CROSS THE REGION FOR THE FIRST HALF

OF TONIGHT AND THAT MAY DELIVER SOME RAIN/SNOW SHOWERS ACROSS THE

AREA...HOWEVER OVERALL IMPACT WILL BE LOW WITH ONLY A FEW

HUNDREDTHS OF AN INCH OF RAIN OR A HALF INCH OF SNOW EXPECTED.

TEMPERATURES ARE NOT EXPECTED TO GO VERY FAR OVERNIGHT WITH

SOUTHERLY FLOW AND CLOUD COVER. MAY SEE THEM FALL SLIGHTLY AT

FIRST THIS EVENING BEFORE HOLDING STEADY OR SLOWLY REBOUNDING

TOWARDS MORNING...GENERALLY IN THE 30S WITH SOME 20S REMAINING

ACROSS EASTERN VERMONT.

CONCERNING GUSTY WIND THREAT...SOUTHWESTERLY FLOW INCREASES OUT AHEAD OF

APPROACHING LOW PRESSURE SYSTEM AFTER 09Z EARLY SUNDAY MORNING.

850 MB JET OF 50-60 KNOTS AND 925 MB JET OF 45-55 KNOTS MOVES

OVERHEAD FOR SUNDAY MORNING. THIS WILL LEAD TO ADVISORY-LEVEL

GUSTS (45-55 MPH) ACROSS MUCH OF THE REGION...ESPECIALLY ACROSS

THE SAINT LAWRENCE VALLEY AND WESTERN ADIRONDACKS OF NEW YORK AND

THE HIGHER ELEVATIONS OF THE GREEN MOUNTAINS IN VERMONT. AMOUNT OF

MIXING REMAINS QUESTIONABLE DUE TO EXPECTED PRECIPITATION...WHICH

WILL DETERMINE HOW MUCH OF THE WINDS ALOFT CAN ACTUALLY MAKE IT

DOWN TO THE SURFACE. WINDS THEN TURN WESTERLY POST-FRONTAL SUNDAY

AFTERNOON.

SNOW SHOWERS AND SQUALLS WILL ALSO POSE A CONCERN. AS SOUTHWEST

FLOW INCREASES TOWARDS SUNDAY MORNING AND COLDER AIR MOVES IN

ALOFT...WILL LIKELY SEE A BRIEF PERIOD OF SOME LAKE EFFECT SNOW

BEFORE WINDS TURN WESTERLY. THIS WILL PRIMARILY AFFECT THE

SAINT LAWRENCE VALLEY...ADIRONDACKS...AND POSSIBLY THE NORTHERN

GREEN MOUNTAINS WITH A DUSTING TO 2 INCHES POSSIBLE. GREATEST CHANCES FOR

SQUALLS WILL OCCUR WITH PASSAGE OF THE COLD FRONT SUNDAY MORNING

ACROSS NORTHERN NEW YORK AND VERMONT SUNDAY AFTERNOON. BRIEF HEAVY

SNOW...WITH ACCUMULATIONS FROM A DUSTING TO 2 INCHES...AND STRONG

GUSTY WINDS CAN BE EXPECTED WITH THESE SQUALLS.

TEMPERATURES WILL FALL RAPIDLY BEHIND FRONTAL PASSAGE...FROM THE

30S SUNDAY MORNING AND INTO THE TEENS/20S BY THE AFTERNOON. THIS

MAY CREATE A FLASH FREEZE ON AREA ROADWAYS.

I'm not a big fan of high winds. Only because I lose power here pretty easily when it gets to blowin'. Downtown MPV never seems to lose power but here on the outskirts of town and up the hill where I am all it takes is a bear farting loud enough and in the right spot for the lights go out...

Hehe, well, due solely to the aforementioned reason, I guess so. As a weather weenie, I love all extreme events (except for heat waves). I lived in the Florida panhandle for 18 years prior to moving up here in '98, so I've seen a few good hurricanes...exciting stuff, those.

From BTV...ugh...

AS OF 744 PM EST SATURDAY...AFTER PERUSING MULTIPLE MODEL SETS AND

CORRESPONDING SOUNDING PROFILES...HAVE OPTED TO UPGRADE PORTIONS

OF OUR EXISTING WIND ADVISORY TO A HIGH WIND WARNING...NAMELY

ACROSS MUCH OF NRN NY AND EXTREME NWRN VT. INTERESTING SETUP AS

APPROACHING CLIPPER SYSTEM WILL BE ACCOMPANIED BY TWO DISCRETE

FRONTAL BOUNDARIES...THE LATTER BEING A TRUE ARCTIC FRONT. IT IS

DURING THE INITIAL COLD THERMAL ADVECTION SURGE BEHIND THE FIRST

BOUNDARY HOWEVER THAT POTENTIAL FOR STRONGEST WINDS WILL

OCCUR...AND TIME FRAME OF STRONGEST GUSTS FROM EARLY TOMORROW

MORNING THROUGH THE EARLY TO MID AFTERNOON HOURS ON SUNDAY STILL

LOOKS ON TRACK. IMPRESSIVE H5 HEIGHT/6-HR PRESSURE FALLS AND

CORRESPONDING STRONG ISALLOBARIC FLOW LEADS TO INCREASED

CONFIDENCE FOR POTENTIAL DAMAGING GUSTS INTO THE 55 TO 65 MPH

RANGE...ESPECIALLY WHEN CONSIDERING THE STEEPENING POST-FRONTAL

LOW TO MID LEVEL LAPSE RATES AND EVEN SOME MARGINAL INSTABILITY TO

200 J/KG AS ROBUST UPPER DISTURBANCE PASSES.

Sweet, yea losing power bites. Nothing good ever comes out of that. Its a double edge sword for us extreme lovers who own homes.

Wow it's mild out there...lots of mid/upper 30s, especially higher terrain above 1000ft.

Liking the thunder snow moving over Lake Ontario with the front...BTV also mentioned lightning back there over the lakes. Strong dynamics.

Wow... Laconia is 21 and about four miles away in Gilford one of the PWS stations is 36.

At one point late last night I was 36F with a breezy S wind and you were like 28-29F and Plymouth in the low 20s. We couldn't decouple on the hill until after midnight.

Check out the MVL obs early this morning... pretty classic.  Wind is calm and the temp goes below freezing... wind is pesky, and the temp jumps into the low 40s.

 

I love the 4:54am ob where it went calm and dropped to 28F, then went back into the low 40s as the breeze picked up.

 

We were below freezing through 1am, then all over the place after that.

Just south of the Whites in NH they got down to the low to mid 10s in many spots. It was a crazy night temp wise.

Yeah, weird night/morning temp-wise.  23 for an early morning temp, 25 at last look and yet I see all kinds of 40s in the Champ Valley.

 

Should be interesting to see what that front has in store when it comes through.

 

Go Pats, yo.

Lots of good weather for Central NE coming up.  Solid squall line in Vermont with snow and high winds for today..  Arctic cold.  NAM/SREF's seem to want to bring the Norlan trough further north with each run.  Con fous up to .67" on 12Z NAM,  and then snow possiblities and continued cold in the late period.  Pats game to look forward to too!!

 

Good stuff.   Enjoy!

Temp 37F at 11:15am.   Got very dark,  strong winds with a rain shower in past 20 minutes.  Snow level looks like around 1500 feet.  Interesting to see how warm it still is way to the NW.  Montreal is still in the 30's at 11am.  I was expecting a sharp drop but it looks like cold air is just going to slowly come in this PM
