Mountain Weather Forecast -Time: 0900

Hopefully we will squeeze a few more inches of snow out of this before it dries up later today. The atmosphere will begin to stabilize under rising barometric pressure this afternoon. Dry and clear weather will start tonight and last through most of the weekend.

Long-range: Warm southwest flow is expected to generate high freezing levels and a chance of rain on Sunday and Monday.

Note: I will be touring in the Selkirk Mountains for the next 6 days and unable to provide a weather forecast until next Thursday. For your weather fix go to:
