forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 7 PM PST Saturday 3 February 1996 for
tonight Sunday and Monday.
The next scheduled forecast will be issued at 5 AM Sunday.

Synopsis for coastal BC.
    A major change is taking place in the weather pattern over 
western Canada. The ridge of high pressure and dome of cold arctic
air that gave sunny skies to the coast for the last few days has
shifted eastward. A wetter but milder weather pattern is now
developing along the coast. Unfortunately the transition from
a cold arctic pattern to a moist Pacific pattern is going to be a
messy one in the south. A variety of precipitation has developed this
afternoon with rain on the west side of Vancouver Island flurries in
Victoria and freezing rain near nanaimo. Most areas can expect snow
or freezing rain tonight changing to rain by Sunday morning. Snow and
freezing rain warnings are in effect for much of the south coast with
local snowfalls of up to 8 centimetres possible along the coast and
up to 15 centimetres in extreme eastern areas before the snow finally
changes to rain.
     The north coast will escape the worst of the weather but can
still expect showers along the coast and snow inland. As temperatures
warm aloft the threat of freezing rain will spread to the north and
central coast.
     A second system will bring more rain to the coast Sunday night
and Monday.

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Wednesday 3 January 1996 valid until midnight Thursday.  The next
scheduled forecast will be issued at 6:00 AM PST Thursday.

Precipitation intensity is forecast as an
hourly rate of snowfall water equivalent.

no pcpn   up to 2.5 mm   2.5 to 7.5 mm   more than 7.5 mm

discussion.
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
and surface inland overnight and Thursday.

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
inland early sun leaving the coast under an unstable showery and
somewhat cooler pattern again.

South coast mountains.
Warnings.. None.
Occasional light flurries eastern slopes this evening then nil.
Mountaintop winds..northwest 20 km/h becoming northeast 20 km/h
overnight. Outflow winds 30 to 40 km/h at the surface.
