11/26/2011 Weather
General Discussion: The snow expected last night stalled just off of the BC coast, so it didn’t quite make it to the mountains, bummer. Today will be gray with light mixed rain and snow possible. Most of the moisture is just to our north. A warm front will bring warmer temperatures and rain to the Pass tomorrow.
Long-term: A cold front expected to move in tomorrow evening will bring and end to the precipitation and lower temperatures. The weather pattern will change Monday as the northern jet stream shifts north into Canada. This will bring mild temperatures and a prolonged dry period.
