44 cm of new in 48 hrs is all ways welcome around here.

Two masses of air collided over Whistler last night and today producing a good snowfall.

All terrain and lifts opened today with the exception of Symphony chair.

A cool 24 hrs is next with plummeting temperatures tonight and tomorrow.

Alpine high minus 6. Windchill minus 25 in the morning.
Freezing level valley bottom.
Winds northeast 20 to 30 km/h shifting to southwest 10 to 20 km/h late in the afternoon.
Cold Smoke

Colder Arctic air is also becoming more entrenched across the area on the wings of a cold front moving southwards across the South Coast mountains. The accompanying cold dry outflow winds will help to shunt the cloud and snow out of the region later tonight and Thursday along with a return to sunnier conditions.

Powder for the people

Whistler Weather forecast

A 1008 mb low off Vancouver island tonight will meet arctic air possibly resulting in a good dump of snow (the conditions will have to be just right for this to happen) The latest models would seem to say most off this precip will fall to the south and east of us tonight not resulting in a huge snowfall here tonight. Mountain top winds currently are 60 gusting 90km/ph from the south as of 6pm with not much precip right now.6pm IRSat
Near 5 cm of snow is expected over most of the south coast with local amounts up to -10-15 cm near Whistler and much more in the alpine.

By mid day tomorrow we may see some clearing mid/late afternoon. Some clearing in behind Wednesday with plummiting temperatures late in the day will suck all the moisture out of the snow resulting in some of the better riding conditions of the season. Be prepared with an extra layer of clothing for late in the day Wednesday as gusty northeast arctic winds will breifly pick up.
Deep in the forest (somewhere)

In behind a cloudy day for Thursday with low temps, warmer Friday, a mix of sun and cloud though early in the day Saturday freezing level in the valley.

The next major system comes in early Sunday right now with some warming to around 1500m.

The long range looks good with a strong jet stream taking aim at us through next week with cool temperatures.

Snow finally

Whistler Weather forecast

A large 918mb low pressure system spinning off the Oregon coast will slowly edge towards the region in the next couple of days. Sending in waves of moisture.

A weak trough in advance of the main system may give some light precipitation starting around noon. A second and stronger disturbance will bring more organized precipitation over the South Coast Mountains by this afternoon and into tonight.

In the wake of that disturbance drier conditions can be expected on Monday. However the main low pressure system will spread another round of organized precipitation to the region late in the day Monday bringing more snow.

Freezing levels this morning 1500 metres to 2000 metres, dropping to 1000 metres this afternoon.

Mountain top winds southeast 30 km/h gusting to 50.

The low pressure system will establish off the South Coast on Tuesday bringing low freezing levels and periods of snow.

Arctic air will advance towards the region on Wednesday spreading colder air and more snow. Drier and warmer conditions are expected on Thursday as the Arctic air retreats.

One more day of sun

Whistler Weather forecast

A final dry and mainly sunny day will continue over the South Coast today. Increasing higher cloud will spread northwards across the region tonight ahead of a couple of upper disturbances expected on Sunday with the first one arriving in the morning. A second and wetter band of moisture is expected over the region Sunday afternoon or in the early evening

On Monday a low centre will move to lie to the west of Vancouver Island bringing more organized precipitation over the region. As a surface trough becomes established over the South Coast on Tuesday freezing levels should begin to lower over the region.
They will continue to lower on Wednesday as arctic air moving southwards over the BC Interior approaches southwestern BC.

Sunny / cool

Whistler Weather forecast

An arctic ridge of high pressure over northern BC will slowly weaken Monday and Tuesday with dry and cool conditions continuing.



The ridge will remain in place right through the week deflecting all chances of precipitation. The "Rex block weather pattern" in this case is hugging the West Coast of the Washington state

A Rex block sets up with a strong high-pressure ridge adjacent to a strong low-pressure trough. A large ridge is north of a large trough. Air flow in the north Pacific curves around the ridge and then around the trough in the Southwest US. This causes the air to swing in loops near the same longitude but forces the air to a much lower latitude. The wind flow makes little progress to the east due to the "half figure 8" rotation the air must endure. All precipitation is then deflected south to california.

Light Flurries

Whistler Weather forecast

A high pressure ridge centered near northern alberta continues to hold deflecting all the weather to the south of us.

A weak upper disturbance will bring clouds and some light flurries to the area this morning. However, little is expected in the way of accumulations. Friday will be cool and drier except for Friday night and into Saturday when another upper level disturbance will approach the area bringing the chance of light flurries.

Cool and unsettled conditions are expected for the most part through the weekend. Some more light flurries are expected on Saturday. Then Sunday and Monday will remain cool and unsettled with no significant snowfall accumulations expected.

Sunny skies

Whistler Weather forecast

A weakening low pressure system continues to move south today with skies clearing this morning as a ridge of high pressure builds in behind. Another frontal system will approach the region overnight with isolated flurries possible through early Thursday afternoon.

Otherwise all the weather for the next week is going south to northern California.

Generally dry conditions are expected through Saturday as a weak ridge of high pressure diverts weather systems to our south. An upper trough of low pressure will give increased cloud and a low chance of flurries on Sunday.

West Northwest flow developing

Whistler Weather forecast

The ridge of high pressure giving dry conditions will weaken today. A weak cold front will slump across the south coast tonight bringing a few flurries and a cooling trend tonight through Friday morning. Gusty northerly winds will follow the cold front on Friday as a clearing trend develops.

Changes in the weather pattern will bring a series of disturbances for the weekend. The first weak system will bring flurries that will end Friday morning with partial clearing expected Friday afternoon.

A stronger disturbance will approach the region on Saturday bringing flurries. Temperatures will rise slightly during the day

The remnants of a good sized pacific storm to the north of us will slide down the BC coast. By the time it gets here it may not have much left in it. The third disturbance will come through on early Sunday morning bringing a bit more snow and a cooling and clearing trend. Expect light amounts of precip through the long range, most of this precip will go south.

Long range:(subject to change daily at this point) It would appear another arctic ridge may be developing over northerneastern BC deflecting this westerly flow south. The dreaded 1024mb high that has been deflecting snow away from the region..(go away) Temperatures at treeline will be in the -12C to -15C for this period. Wednesday should bring more precip from a system to the south.
