forecasts for coastal British Columbia issued by the Pacific weather
centre of Environment Canada at 4 PM PST Thursday 30 november 1995
for tonight Friday and Saturday.
The next scheduled forecast will be issued at 7 PM.

Synopsis for coastal BC.
  An unsettled cloudy and showery pattern prevailed over the coast
today as a low pressure system continued to deepen over the northern
gulf of Alaska.  This pattern will continue through Saturday as the
low begins to edge in over the coast.  Weak disturbances embedded in
the flow will enhance the shower activity from time to time and as
the freezing level continues to lower snow flurries can be expected
over higher terrain and over areas further inland.  In the north the
arctic front lies across the coast and periods of snow can be
expected north of the front.  A snowfall warning has been issued for
the terrace - stewart areas for tonight and Friday with 15 to 20
centimetres of snow expected.  Temperatures are still above normal in
the south and close to normal values in the north. Cooler
temperatures are expected on the weekend.

mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Thursday 30 november 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.

discussion.
 A broad upper trof continues over the gulf of Alaska maintaining a
flow of fairly moist and unstable air over the coast. The main
frontal band lies just south of the province with a weak wave moving
along it and just brushing the south coast this afternoon. North of
the front weak short waves are rotating around in the trof but
positioning and timing of these is very difficult.  Over the next
36 hours the upper trof will deepen as a significant short wave digs
southeastward from Alaska. The main effect will be lowered heights
and increased convection over the coast as the upper trof further
supports the surface low and trof already in place across the
northern gulf/north coast. The surface low will drop south then
swing eastward moving in over the southern panhandle late fri
afternoon/evening. The arctic front will remain quasi-stationary
southern panhandle - kitimat - south-southeastward until the low
begins to move inland then it should retreat northeastward to a
stewart - terrace - southeastward line.

Freezing level..in the south 1200 metres lowering to 1000 metres to
night and 800 metres fri evening. Central..steady near 700 metres.
North coast..near 500 metres to surface inland and north.

Extended outlook.
The upper trof will move in over the province on the weekend
maintaining a very cool and unstable pattern over the coast.
Freezing levels will continue to drop and snowflurries will
continue. By mon a longwave upper ridge will develop over western
Alaska putting the coast under a drier and colder northwesterly
flow.

South coast mountains.

confidence..low. Timing of shortwave features could be haywire and
precip amounts could vary considerably. One area to watch is the
north coast. If the low stays out on the coast and intensifies a
heavy snow event could develop. In the extended outlook the main
problem is the position of the main frontal stream which could shift
far enough north to catch the cascades on sun.
