forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 7 PM PST Thursday 8 February 1996 for
tonight Friday and Saturday.
The next scheduled forecast will be issued at 5 AM Friday.
Synopsis for coastal BC.
It's almost over...the front that soaked the south coast today is
sliding into the interior. Rain is now tapering to showers and gusty
winds will develop overnight marking a welcome transition to a much
drier weather pattern.
The ridge of high pressure forecast to poke up across the coast
from the southwest will bring back the sunshine. This ridge is of a
completely different nature than the last one which kept the coast in
frigid arctic air for about a week. Fridays ridge will be much
warmer but not nearly as strong and will likely begin breaking down
by the end of the weekend.
On the north coast cool unstable air May produce a few showers or
flurries tonight. Offshore another frontal system will clip the
northern Charlottes and perhaps northernmost part of the mainland
Friday and Saturday. But further south a mix of clouds and sun is
expected.

A big upper ridge covers the gulf of Alaska with a northerly flow
over the coast. The ridge supports a 1040 mb arctic surface high
centered over the central yukon. This high centre will move to
north-central BC by Thursday afternoon. The arctic front extends
from near rosespit on the queen Charlottes to vicinty bella coola -
southeastwards. Overnight the central and southern portions will
push out to queen charlotte Sound on the central coast and strait of
georgia in the south. Cloud associated with the front May generate
some isolated light flurries over eastern slopes tonight. Otherwise
conditions will be mainly clear and cold with strong surface outflow
winds through the inlets and valleys.
Freezing level..surface central and north coasts. In the south near
1400 metres coast to 1000 metres inland lowering to 600 metres coast

Extended outlook.
On Friday the surface high will move to central sask and the upper
high will drift eastward allowing overrunning cloud on the next
series of fronts to reach the coast in the evening and precipitation
to spread onto the coast overnight. On sat the upper high will move
inland bringing a mild southwest flow over the coast with rising
freezing levels and significant precipitation. The front will move
