The first outlook of the "DREADED "S" WORD. Not sure if it will occur though as temps remain realitively warm. We would have to "wet-bulb" down some of the cooler air aloft in a "heavier burst" of rain showers.

Very beautiful pictures!

Today -1.6/+5.9, some rain this evening with 0.4 mm.

Rain and snow for this night and tomorrow, winter is getting closer this weekend and I think we should not get anymore +10C before spring.

For the webcams, you should see some snow tomorrow on my website.

Have a great one !

Hello everybody,

-0.8C this morning with overcast conditions.

Temperatures ranging from -9 to +2 in the territory. Some snow in south Yukon.

This weekend was pretty cool with flurries, some snow on the ground on sunday morning.

This week should be colder, with some snow for today and tomorrow, then a mix of sun and clouds.

Perhaps our first -10, and high lower tha 0C.

Wait & See :pimp:!

Well you knew it was a "matter of time". Had my first snow of the season as a heavier "convective" shower moved through and the winds kicked up from 13 to 33kt....as the shower "wet-bulbed" down some cooler air. Had a nice mix of rain, sleet, and snow for a little less than 10 minutes....no surprise though as earlier in the day we could see the "white haze" mixed in with the shower to the W-NW coming from a TCU and the freezing level dropped from 2100 feet during the day to 1900 feet on tonight's RAOB launch....and noticed an MCV dropping southeast with enhanced cloud tops on the IR SAT....obs are below....:thumbsup:....:snowwindow:

Looks like more snow may be on the way....an exert from the morning discussion....

BERING SEA/ALEUTIANS...

POTENT VORTICITY CENTER WILL CONTINUE TO DIVE SOUTHEAST ACROSS THE

EASTERN BERING THROUGH THIS MORNING AND WILL ENTER THE NORTH PACIFIC

BY THIS AFTERNOON. EXPECT TO SEE INCREASED RAIN SHOWER ACTIVITY AND

COOLER AIR BEHIND THE SYSTEM AS IT PASSES. OTHERWISE...A SERIES OF

WEATHER FRONTS IN FAST SOUTHWEST FLOW ALOFT WILL BRING A RENEWED PUSH

OF GALE FORCE WINDS AND RAIN AND RAIN SHOWERS TO THE REGION FROM WEST

TO EAST AND PERSISTING THROUGH THE END OF THE WEEK.

.LONG TERM FORECAST...

THE PATTERN WILL TRANSITION FROM CLEAR AND DRY TO CLOUDY AND WET LATE

THIS WEEK...AND THEN PERSIST FOR THE MOST PART OVER MOST OF

SOUTHCENTRAL...ESPECIALLY CLOSER TOWARDS THE GULF...AS SOUTHWEST LATE

THIS WEEK GRADUALLY VEERS TO A MORE SOUTHERLY FLOW FOR THE EARLY TO

MIDDLE PARTS OF NEXT WEEK. A LARGE SCALE UPPER LEVEL TROUGH

EVENTUALLY BUILDS ACROSS THE BERING SEA BY EARLY NEXT WEEK...BRINGING

A BETTER CHANCE OF SNOW SHOWERS OVER PARTS OF THE BERING AND

SOUTHWEST ALASKA THAT HAVE YET TO SEE IT THUS FAR THIS SEASON.

OVERALL CONFIDENCE IS GENERALLY HIGH GIVEN THE GOOD MODEL AGREEMENT

IN THE SYNOPTIC PATTERN.

Radiational cooling at elevation:

State low this morning as of 12Z. Anaktuvuk Pass 643ft ASL. Zero. Note the contrast to the other sites around it. Mainly because it is a mountain pass along the Brooks Range, but as the surface ridge moved over, clouds cleared and winds went calm. As soon as the low deck moved in temps jumped back up to 12F.

Hello everybody,

0C this morning, snow and 1 to 2 cm on the ground:

111012-webcammeteowhitehorse2.jpg

Temperatures ranging from -7 to +3 on the territory, mainly between -2 and +3 in the south.

Great difference in the forecast between EC and Wxsim even if they both agree on milder temperatures for the weekend, I think everything will depend on snow on ground,

Great! Is that your first sticking snow of the season?

I would say yes, it is our fourth snowfall, but it is the most important with 6 cm on the ground (very wet).

We have now 0.4C, it is still snowing a bit.

If the snow stays on the ground tomorrow (with some frost during the night), we may be close to the -10C on thursday morning.

-0.9C this morning, we should have got an aditionnal 1 to 2 cm on the ground.

Temperatures ranging from -13 and +3 on the territory, here we have a low of -0.9C.

If it is not too mild and we keep some snow on ground, it may be cold on Thursday night with a low close to -10C.

Wait & See :pimp:!

I see that it's a webcam, but take some pics during the day! We all want to see them...

By the way, what's your average annual snowfall up there?

With the next low pressure system moving toward southcentral Alaska, the pressure gradient is increasing and the Turnagain Arm wind is in full effect. Amazing the difference between the west side of town and the higher elevations. I can hear the wind howling on the hillside.

Hello everybody,

-3.9C this morning. It is pretty mild when you consider a sky perfectly clear and no wind.

Lows between -14 and -1 on the territory, as far as I remember it is the first time all the temperatures are below zero this season: Temperatures Yukon

Temperatures will be mild for the upcoming days, and snow on ground should be away by the end of the week.

Have a good day !

Hey guys realatively new to the forum, and hope this is the correct area to ask this question. I am from North Carolina but am looking to make it out to BC for some storm watching, out of the winter months, what in you guys opinion is the best month for that? I've noticed November has the highest rainfall totals typically. Thanks!

I do not know anything about the BC climate :(.... living north to 60s....

Today we got some snow during the night and then a mix of sun and clouds with a high of 5.1C and wind blowing from south.

Upcoming days should be cooler and dry.

Sorry, I probably should have been more specific also. I'm talking about Vancouver Island when I say BC. Just looking for insight, I can look at data on different sites, but planning a trip like that I was hoping to get some insight from people more locally that know all the dynamics better. Thanks!

I believe November through February....but the bigger storms hit up here in the Aleutian Islands. Will check though for you for down there.

Here is something you don't see often in the FAR WEST END OF THE ALEUTIAN ISLANDS....let alone over a 2 by 4 mile sized island....:lightning:
