Alpine Forecast Whistler

Posted on Friday, March 05, 2010

Sunshine

A weak front will dissipate over Vancouver Island today as a ridge of high pressure begins to build over the South Coast. Clouds and a chance of flurries will likely persist through the morning but the building ridge will produce some clearing by this afternoon. The ridge will continue to build tonight and will bring a very nice day on Saturday with sunshine and mild temperatures.

A cold front will reach the coast on Sunday night bringing snow by Sunday evening and will usher in a much colder and snowy pattern that would be typical of mid winter. A weak ridge of high pressure will build in the wake of the cold front on Monday with temperatures remaining relatively cold. The next Pacific front will move in late Tuesday but with little in the way of warm air, leading to more snow and a low freezing level. The period from Monday onwards is shaping up to be the coldest we have seen since December.
