forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 4 PM PST Tuesday 14 november 1995 for
tonight Wednesday and Thursday.
The next scheduled forecast will be issued at 7 PM.

Synopsis for coastal BC.
  The warm moist flow continues along the coast with some rain or
drizzle reported in all regions.  Heaviest rainfalls are currently in
the central and north coasts.  Warm air is slowly pushing into the
inland sections.  This will change the snow falling in the inland
north coast to rain later this evening.  The frontal system
responsible for this weather is forecast to move to the coast early
Wednesday morning and then rapidly inland.  In the wake of the system
frequent showers will continue.  Another more organized system is
expected to move to the north coast early Thursday and sag southwards
spreading rain into the south coast by late afternoon.
  A deep low moving up the coast has developed strong winds from
northern Vancouver Island northward with wind warnings in effect for
those regions.  Wind speeds are forecast to be 40 to 90 km/h.
Winds will slowly abate in the wake of the frontal system.

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Tuesday 14 november 1995 valid until midnight Wednesday.  The
next scheduled forecast will be issued at 6:00 AM PST Wednesday.

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.
   The frontal wave continues to be the weather feature of focus.
The wave is currently in the vicinity of 49n/136w and moving
northeast to lie just southeast of terrace at 4am Wednesday and on
to near the elbow of the BC/alberta border by midnight.  The sytem
is very complex in that it has a trowal - or trough of warm air
aloft - extending almost due west from the wave which will hang back
across the coast as the wave moves inland.  Very warm air continues
in the warm sector of the wave with the warm front currently from
the wave east through bella coola and the cold front southward.  The
system will maintain this configuration throughout the period.  The
cold front should be south from the wave through campbell River at
4am.  Moderate to heavy precipitation and strong winds accompany the
system.

Freezing level.. South.. 3000 metres south to 2800 metres north
lowering to 2100 metres along the cold front and to 1500 to 1700
metres Wednesday evening. North..with the increasing warm air aloft
with the arriving warm front the air mass will be warming in general
aloft with an above freezing layer developing with levels becoming
established tonight at 1800 metres coast to 140 metres inland.
Levels dropping to near 800 metres Wednesday afternoon.

Extended outlook.
Thursday a southwest flow aloft will maintain a moist onshore flow
with clouds and showers.  Another frontal system will push onshore
early stretching from the Charlottes southwest.  This cold front is
forecast to be in a northeast-southwest line through southern
Vancouver Island Thursday afternoon.  Friday the onshore flow
continues with a long wave trough swinging to the coast by evening
with another front in an northeast-southwest line through central
Vancouver Island by Friday afternoon.  The flow off the Pacific
through this period remains fairly mild.  Saturday the trough swings
inland with more rain.  Freezing levels begin to plunge generally
below 1500 metres south and 500 metres north.

South coast mountains.
Cloud with occasional light rain or drizzle overnight turning to
moderate rain early Wednesday. Rain will be occasionally heavy in
upslope areas. The steady rain will ease to a few light
locally moderate showers mid to late afternoon.
Mountaintop winds.. South to southwest 50 to 70 km/h tonight
rising to 70 to 90 km/h Wednesday morning. Winds easing to southwest
40 to 60 km/h mid day.

confidence..fair to good. Always tricky with warming aloft in north
coast and subsequent precipitation types and amounts. Move to
warmer air is happening but a risk that warming wont be complete
and deep isothermal layers allow snow or mixed rain and snow to
persist in far northern locations.
