Nice sun dogs! That was one thing I enjoyed in ND. Lots of ice crystals, light pillars and huge sun dogs.

As promised, here are some pictures I took this afternoon (by -30/-31):

This evening, a lot of temperatures are already below -30C, here we have -29.5C at 6:30.

The night may be frigid if the sky stays clear.

That's just brutal. We never got anything that bitterly cold in ND till mid-winter. At least the wind doesn't blow much up there.

Awesome pictures. You can tell how cold it is. In ND we would get cold stuff like that all the time..I am used to it. I love it when the ice crystals would fill the sky with all sorts of neat optical phenomena.

how do you dress when you go outside? how do you keep your house warm??? i can't even imagine these temperatures...

Hello,

I wear several layers. Dow to -30C, I usually wear warm underwears + a warm jacket (Canada Goose) and lined trousers + 2 pairs of sockets + warm boots + hat. Below, I add a sweater.

This afternoon, we got -24C, we hiked in the Fish Lake area. It was magic, with ice crystal and temperatures ranging between -32 and -36C. I will post some pictures tomorrow.

Good morning everybody,

Today, low of -28.1C, we now have -24.3C with some light snow.

Lows between -40C (Dawson) and -22C (Old Crow) in the territory this morning. It warmed up, but we will keep the cold all the week (apart here in around Wednesday and Thursday).

Here are some pictures I took yesterday around Fish Lake (between -32 and -36C):

It was between 2:30 and 4:00 in the afternoon at sunset. You can see some ice crystals fog patches, a sundog, the creek never freezes.

Classic fall storm moving into the Coast. Definitely a wind producer as well as heavy rain/snow at higher elevations. Sub 975 mb sfc low right now.

Metro Vancouver

9:08 PM PST Monday 21 November 2011

Wind warning for

Metro Vancouver continued

Southeasterly winds of 80 to 100 km/h over coastal sections of the central coast, north and West Vancouver Island tonight.

South to southeast winds of 70 to 90 km/h over Metro Vancouver, Fraser Valley, Southern Howe Sound, East Vancouver Island, Sunshine Coast, and Southern Gulf Islands tonight.

A burst of southwest inflow of 80 to 100 km/h affecting inlets of the central coast Tuesday morning.

This is a warning that potentially damaging winds are expected or occurring in these regions. Monitor weather conditions..Listen for updated statements.

Two approaching low pressure disturbances from the Pacific ocean will bring yet another round of unfavourable weather to many regions in coastal British Columbia tonight. Heavy snowfall will continue over Whistler and will begin over Central Coast - inland sections early this evening. About 10 to 15 cm of the white stuff is expected for Central Coast - inland sections while another 20 to 30 cm will likely fall over Whistler tonight.

Rain at times heavy is forecast to develop this evening over the north shore of Vancouver, Howe Sound, the Sunshine Coast and areas from Comox to Parksville on East Vancouver Island. 60 mm of rain is possible over these regions by Tuesday morning.

Strong southeasterly winds will redevelop with the arrival of the next system tonight for much of coastal British Columbia including the Lower Mainland. These winds are expected to diminish quickly Tuesday morning in the wake of the disturbance.

With the track of the low into the central coast of British Columbia, a quick burst of southwesterly inflow of 80 to 100 km/h is possible near Bella Coola Tuesday morning.

I could understand if it never freezes solid, but does it at least develop a layer of ice on top in the winter? Mixing would certainly delay the freezing process, but I couldn't imagine not getting some surface ice at those temperatures!

From NWS Fairbanks:

INTERIOR...A MODERATELY STRONG PRESSURE GRADIENT TODAY INTO TONIGHT

WILL ONLY VERY SLOWLY BEGIN TO RELAX WEDNESDAY. A VERY COLD AIRMASS

ALOFT WILL VERY SLOWLY MODERATE THE NEXT TWO DAYS. 500 MB HEIGHTS

BOTTOMED OUT AT 490 DM WITH AN 850 MB TEMP OF -30.5C AT FAIRBANKS

YESTERDAY AFTERNOON AT 00Z. THIS WAS SIGNIFICANTLY COLDER ALOFT

THAN LAST WEEK. IT WAS A GOOD THING THAT THE UPPER LOW PASTED TO

THE WEST OF THE INTERIOR AND ALLOWED SOME CLOUDS AND WEAK

OVERRUNNING TO HELP TEMPER THE COLD.

TO GIVE SOME PERSPECTIVE THE 500 MB HEIGHT OF 490 DM IS AN ALL-TIME

RECORD LOW 500 MB HEIGHT AT FAIRBANKS FOR THE MONTH OF NOVEMBER.

AT MCGRATH...THE 500 MB HEIGHT OF 483 DM BREAKS THE ALL-TIME

NOVEMBER RECORD OF 490 DM. THE 850 MB TEMPS ARE IN THE TOP 5

PERCENTILE...BUT NOT RECORDS.

Also, some lovely -70 wind chills in Atigun Pass, on the new wind chill scale. That would be very impressive in January, much less November!

NORTHEASTERN BROOKS RANGE-

INCLUDING...ANAKTUVUK PASS...ATIGUN PASS...GALBRAITH LAKE...

SAGWON...FRANKLIN BLUFFS

412 AM AKST TUE NOV 22 2011

...WINTER STORM WARNING IN EFFECT UNTIL 6 AM AKST WEDNESDAY

AT ATIGUN PASS...

.TODAY...CLOUDY. FLURRIES. AREAS OF BLOWING SNOW THROUGH PASSES

WITH LOCALLY POOR VISIBILITY. TEMPERATURES STEADY FROM 25 TO 40

BELOW. NORTH WINDS AROUND 15 MPH. GUSTS TO 35 MPH IN PASSES WITH

WIND CHILL TO 70 BELOW AT ATIGUN PASS.

.TONIGHT...MOSTLY CLOUDY. AREAS OF BLOWING SNOW THROUGH PASSES

WITH LOCALLY POOR VISIBILITY. TEMPERATURES 25 TO 40 BELOW. NORTH

WINDS AROUND 15 MPH. GUSTS TO 30 MPH IN PASSES WITH WIND CHILL TO

70 BELOW AT ATIGUN PASS.

I was just looking at that yesterday. Makes sense when the whole polar vortex displaces over top of you.

Valdez had sustained winds of 100mph and gusts to 120mph with this event. What makes this event so rare is the upper level winds were from the south! These winds were created by the combination of surface pressure gradient (High over the interior, Low in the Gulf of Alaska) and cold air in the Copper River Basin being held back by the Chugach. The Gulkana(Copper River Basin) to Cordova(Along the coast near Valdez) pressure difference was 22mb!

To put it into perspective the models were only forecasting 50kt in the low/mid levels that was available to mix to the surface. Essentially a katabatic driven event!

There is a small dam on this lake, and I just wonder if it does not explain why it never freezes. Just a guess !

I already told you that it may be a dam but it is funny because I just read a news release today about why water doesn't need to freeze until -55F: My link....
