centre of Environment Canada at 5 AM PST Saturday 3 February 1996 for
today and Sunday.
The next scheduled forecast will be issued at 10 AM.

Synopsis for coastal BC.
  What a difference a day makes...
  The ridge of high pressure responsible for the recent cold spell is
on the move eastward into the prairies.  This will allow a
southwesterly flow of moist Pacific air to invade coastal British
Columbia and return our weather to the more normal wet and mild
variety.  The first in a series of disturbances will approach the
area tonight..with rain expected on the coast..snow inland..and a
risk of freezing rain through some valleys as cold air remains
trapped a little longer.  Mild and wet weather will continue through
midweek.

Freezing level..south..surface this morning rising to 1200 metres
tonight and to 1800 metres Sunday.  Below freezing layers at the
surface persisting through some inlets and valleys.

Pacific weather centre of Environment Canada in Vancouver at 2:00 PM

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.
