Ridge of high pressure for today in a Northerly flow aloft. Slightly inverted temperatures. Some cloud will move in from the North this pm, but a mostly sunny day. Unsettled for Thursday and Friday with a mix of sun and cloud. Ridge slowly drifts West with some cloud from the Arctic low moving down the central part of BC. Warmer temperatures can be expected during this period as well. Overcast Saturday with colder air moving in from the Northeast, with the Arctic low bringing some light snow by Saturday afternoon. Periods of light snow continue into Sunday with the freezing level dropping. Cold gusty arctic air will bring a chilly blast! Cold overcast conditions early next week. Guesstimates: no precipitation until Saturday. 2-5 cm by Sunday am, 2-6 cm by Monday am.

FROM AVALANCHE CANADA:

Travel and Terrain Advice

Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.

Approach steep open slopes at and below tree line cautiously, buried surface hoar may exist.

Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
