Synopsis for coastal BC.
  A weak disturbance is sliding across coast this afternoon

arctic air has begun to spill out through the north coast valleys
and inlets. This arctic outflow will spread to the central coast
overnight and to the south coast midday Thursday. The arctic outflow
warning for the north coast has been extended to south coast regions
that will be affected. Scattered snowflurries will accompany the
arctic air as it spills out to the coast. Snowfall accumulations are
expected to be light except for local areas along the east side of
Vancouver Island where additional moisture will be picked up from
strait of georgia.  Temperatures will be much colder than normal
along with the added effect of the wind giving high windchill

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Wednesday 6 December 1995 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.
The big upper ridge continues over western Alaska supporting the
surface high centered over the central yukon and producing a
west-northwesterly flow aloft over the coast. A weak shortwave
trough embedded in this flow lies northeast-southwest through
terrace. At the surface a 1058 mb high lies over the yukon with a
ridge extending southeast to mackenzie. A surface low lies over the
Cariboo with a trough extending back to prince rupert. By thurs
morning the low and upper trough will move to the kootenays with
surface trough extending from the low west-northwestward just off
the mainland coast. The arctic front will lie in this trough. This
afternoon satellite pics show low and mid cloud vicinity of the low
and upper trough and very clear and cold conditions stewart -
northward. The upper trough will generate some flurries over
the central coast tonight and there will likely be some light flurry
activity along the arctic front as it pushes out on the south coast
on thurs.  The outflow has developed through the north coast inlets
and will spread to the central coast overnight and the south coast
thurs afternoon.

Freezing level..near 400 metres along southern mainland coast this
evening lowering to the surface tonight. Surface elsewhere.

Extended outlook.
Cold dry and windy through Saturday as the arctic high continues. On
sun and mon the pattern changes to southwest flow aloft bringing in
moisture for a good snowfall event.

South coast mountains.
Warnings.. Arctic outflow warning.
Occasional light convective tonight and thurs.
Mountaintop winds..northwest 20 to 40 tonight becoming north to
northeast 10 to 20 km/h thurs. Stronger outflow winds developing at

confidence..fair. Position of the arctic front is a bit tricky but
the models all remain very dry with it so its not likely to
generate much precipitation.
