Weather Overview November 27, 2013

Most of B.C. will remain dry today as an upper ridge along the Coast Range this morning moves to the Rockies by late afternoon. A weak AFL between about 1500 and 2000m will persist over Western regions and the western half of the Interior regions until Thursday. West of the ridge a low pressure centre will track towards the Alaska Panhandle this afternoon bringing light to moderate precipitation to White Pass and the North coast. Supported by a strong upper
trough, the front will accelerate tonight across the northern half of the interior pushing moderate precip rates across to the
northern rockies by Thursday. The AFL should be eliminated or weakened for most areas with the cooler air behind the upper trough. A fast moving but weak system will cross B.C. on Friday and
early Saturday before an intense cold front drops down the coast late Saturday. This system will herald a major pattern change as cold arctic air behind plunges southwards, through the central interior Sunday and likely all the way to the south coast by Monday.
