forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 10 AM PST Thursday 7 December 1995
for today and Friday.
The next scheduled forecast will be issued at 4 PM.

Synopsis for coastal BC.
  An arctic cold front across northern Vancouver Island will move
southward today. Strong outflows of arctic air are blowing through
mainland inlets of the north and central coasts this morning and
these winds will spread to the south coast this afternoon.  An
arctic outflow warning is in effect for most coastal areas. Only a
few flurries accompany the front. However there is potential for
significant snowfall amounts later tonight on the east side of
Vancouver Island as the cold air picks up moisture from georgia
strait. Snowfall amounts will be quite variable ranging from a few
centimetres to 15 centimetres in more exposed localities. A snowfall
warning is in effect for east Vancouver Island and greater Victoria.
On Friday conditions are expected to be generally sunny and cold as
arctic air covers the coast.

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Thursday 7 December 1995 valid until midnight Friday.  The next
scheduled forecast will be issued at 6:00 AM PST Friday.

Precipitation intensity is forecast as an
hourly rate of snowfall water equivalent.
  Nil        light          moderate       heavy
no pcpn   up to 2.5 mm   2.5 to 7.5 mm   more than 7.5 mm

discussion.
A very strong high pressure area is centered over the yukon. A ridge
extends southwards through the interior of b.c. Very cold and dry
arctic air is associated with this ridge and will cover the mountain
districts through the period. A strong pressure gradient lies over
the coast from the high pressures in the interior to the lower
pressures offshore and this gradient is generating very strong
outflow winds through mainland inlets and mountain passes. These
winds should ease late Friday.

Freezing level..surface.

Extended outlook.
Continuing cold and dry through Saturday. A Pacific frontal system
will approach the south coast from the southwest late Saturday
spreading cloud over the region late in the day. A more vigorous but
warmer system will follow on Sunday bringing snow.

South coast mountains.
Warnings.. Arctic outflow warning.
Nil tonight and Friday except moderate this afternoon southern
sections.
Mountaintop winds..north to northeast 30 to 40 km/h. Stronger
outflow winds at lower elevations.
