Deja Vu, high will build again today in a Northwesterly flow aloft , but the FL will rise to 3200 meters, after a cooler day on Tuesday. We can expect mostly sunny skies for today. More of the same for Thursday with an increase in cloud as the day progresses. Unsettled weather for Friday, as a very weak cold front pushes onshore with scattered flurries and the FL ranging from 1500 m to 1000 m by the evening. More unsettled weather expected for the weekend but models are differing so time will tell.

Sea to Sky Advisory:

With spring-like conditions continuing to dominate the region, be aware of changing snow conditions during the day and from one aspect to another. Once the crust melts there may be areas of wet snow on steep, sunny slopes or near rocky outcrops.
