A ridge of high pressure remains over the southern interior
today resulting in an AFL and valley clouds. A Pacific frontal system approaching the coast will spread precipitation into the
North and Central Coast and Vancouver Island today and tonight. The front will weaken tomorrow. A low pressure centre will approach the Alaska Panhandle on Wednesday bringing precipitation to White Pass and the North Coast. An upper trough will move across the northern Interior on Thursday.
Confidence is high as both GEM and GFS are similar.
