centre of Environment Canada at 10 AM PST Tuesday 28 november 1995
for today and Wednesday.

Synopsis for coastal BC.
Heavy rain warnings remain in effect for all south coast regions.
A stream of mild moist air continues to give rain to most of the
south coast this morning. Rain at times heavy is expected before the
front associated with this moist flow moves inland Wednesday morning.
Clouds and showers will remain Wednesday afternoon in the moist
airmass to the west of the front.
The north coast will escape most of the rain but can expect to be
brushed by the northern portion of the frontal band. This will
result in mainly cloudy skies and occasional rain today.
Outflow winds through northern mainland inlets will continue to draw
colder air from the interior allowing precipitation to fall in the
form of snow with locally mixed rain and snow over some inland
sections of the north coast.

mountain forecast guidance for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 4 AM PST
Monday 27 november 1995 valid until midnight Tuesday.
The next scheduled guidance will be issued at 2 PM today.
Synopsis.
An arctic front will remain in a northwest to southeast line
just south of dease lake through Wednesday.
A warm moisture-laden frontal band will remain draped across south
coast today then move southeastward out of the region tonight.
Abundant moisture will be brought onto the south coast today and
freezing levels should reach close to 3000 metres over much of the
south by this evening. Northern sections of the central coast as well
as the north coast should generally remain to the north of the
warmest airmass however a second frontal stream is just to the north
of the subtropical stream. This will bring light to moderate
precipitation to the central and north coast mountains tonight.
Freezing levels will rise somewhat with the approach of the second
front.
Freezing level..south..near 2900 metres coast sloping to 1600 metres
inland. Levels rising to 2500 metres inland tonight. Levels lowering
to 1600 metres by Wednesday evening.
North..700 metres except near the surface inland north sections.
Levels rising to 1200 metres coast this afternoon then falling
back to 600 metres Wednesday afternoon.
Extended outlook.
Warm moist baroclinic zone shifts slightly south with time but cold
upper trough remains off coast. This will result in a cooler
but still moist airmass over coast through outlook period.
South coast mountains.

Moderate locally heavy snow highest peaks this morning changing to
rain and becoming locally heavy this afternoon through Wednesday
morning. Light flurries Wednesday afternoon.
