forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 4 PM PST Wednesday 3 January 1996 for
tonight Thursday and Friday.
The next scheduled forecast will be issued at 7 PM.

Synopsis for coastal BC.
  A ridge of high pressure building southward through the interior of
the province will bring drier and cooler air out onto the coast over
for the next while.  Clearing has begun over much of the coast and
will continue tonight with mainly sunny conditions expected for much
of the coast on Thursday.  Outflow winds have begun to develop on the
north and central coasts and will increase as the arctic air pushes
out to the coast this evening.  An arctic outflow warning has been
issued for inlets and valleys on the north and central coasts.
On Friday the ridge will move eastward to the praires allowing a
frontal system from the Pacific to spread cloud and precipitation
onto the coast late in the day.  Temperatures will be slightly cooler
than they have been for the past while.

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.
Mountaintop winds..northwest 20 km/h becoming northeast 20 km/h
