mountain weather forecast for coastal British Columbia issued by the
Pacific weather centre of Environment Canada in Vancouver at 2:00 PM
PST Wednesday 13 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.
  Nil        light          moderate       heavy
no pcpn   up to 2.5 mm   2.5 to 7.5 mm   more than 7.5 mm

discussion.
 An upper low continues to dominate the northern gulf of Alaska with
a slightly diffluent southwesterly flow aloft over the coast. Weak
upper troughs moving along in this flow will combine with the
diffluence to keep conditions fairly unstable through the period.
The leading trough will move up and dissipate over the coast this
evening. Another diffuse trough will follow overnight. A third more
vigorous short wave will arrive thurs morning. A surface low will
form with this short wave near 48n/135w by thurs morning and move to
the central coast thurs evening. A trowal will extend from the low
to a frontal wave over the central Oregon coast thurs morning and
move to the central coast - east-southeastward thurs evening.
The arctic front will remain quasistationary from the southern
panhandle - 60 nm south of terrace - vicinity bella coola then
southeast overnight then retreat to terrace east-southeastward as
the trowal moves in. Occasional flurries are expected along and just
northwest of the arctic front while conditions further north remain
fairly clear and cold. Occasional flurries will continue over the
south coast with some partial clearing at times tonight. Steadier
precip with the trowal should reach the mainland coast mountains mid
morning thurs and cascades thurs around noon.  The combination of
low and trowal could generate fairly significant snowfalls over the
south coast mountains especially southwest facing slopes. Less
significant amounts are expected for duffy lk and allison pass.

Freezing level..south..1200 metres rising to 1500 metres thurs
morning. Central.. 1200 metres lowering to 1000 metres overnight.
North coast..surface north of the arctic front. Elsewhere 1000
metres lowering to 700 metres overnight.

Extended outlook.
A weak upper ridge moves to the coast fri afternoon to bring some
drying and stabilizing. This should mitigate the leading system of
the next series as it crosses sat afternoon. By sun another low and
frontal wave will begin to move in with warming aloft and generous
precip.

South coast mountains.
Warnings.. None.
Western sections..light convective tonight. Light becoming moderate
mid morning thurs. Locally brief periods heavy thurs afternoon.
Easing to light locally moderate convective thurs evening.
Eastern sections..light convective tonight and thurs morning. Light
thurs afternoon.
