forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 7 PM PST Friday 19 January 1996 for
tonight Saturday and Sunday.
The next scheduled forecast will be issued at 5 AM Saturday.

Synopsis for coastal BC.
  Sunny but very cold conditions prevail over the north and central
coasts this evening as arctic air continues to spill out through
the inlets and valleys.  This pattern will continue through the
weekend and arctic outflow warnings remain in effect.  In the south
cloudy skies dominated as the system that brought snow to Victoria 
last night continues to slowly drift away.  As it continues eastward 
some clearing will take place overnight.  However the next system is 
moving steadily across the Pacific and will arrive on the coast early
Saturday.  It will spread snow or a mixture of rain and wet snow to
southern Vancouver Island in the morning and flurries or a mixture of
flurries and showers to the lower mainland later in the day. 
Snowfall warnings have been issued for the east side of Vancouver
Island and inland sections of the west coast.  On Sunday the system
will move slowly away leaving a mix of sun and cloud as well as a
chance of a few morning flurries or showers.  Temperatures will
continue cold.

Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Wednesday 3 January 1996 valid until midnight Thursday.  The next

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.
