continue through Thursday.

.DISCUSSION...
Models are in decent agreement in the short term with ridging
building in over the west coast and remaining over the Interior
through the weekend. An upper level low over Eastern Russia
will lift northward through Friday, while high pressure builds
over Interior Alaska. The next upper storm system looks to move
northward from the Bering Sea and across the Aleutian Islands for
early to mid next week, spreading the next round of precipitation
northward along the West Coast.



West coast...The West Coast will continue to see coastal
snow/inland rain through Friday morning, with high pressure
spreading west out of the interior by late Friday into the
weekend. Snow looks to remain confined to the coastal areas where
temperatures will remain in the upper 20s to lower 30s. Additional
accumulations around 1 to 3 inches. Winds are not much of a
factor, so have cancelled remaining advisories/warnings. Upper
ridging will build across the West Coast over the weekend, with
temperatures warming into the mid 30s to lower 40s. By early next
week, the next upper system will move northward across the
Aleutians and into the Bering Sea. This will once again bring
unsettled weather to the West Coast.

Interior...Melting continues over the Interior as high pressure
dominates the area. Highs will reach into the 50s to low to mid
60s through Saturday. The main concern for the short term looks to
be strong winds across Alaska Range, where winds will reach 50 to
60 mph, with higher gusts possible. Winds look to subside
Thursday night into Friday morning.

Easterly flow will continue along the North Slope through Friday.
This will lead to periods of light snowfall and areas of fog along
the coast. Flow looks to shift northwesterly on Saturday as the
current upper system off the West Coast shifts north of the area.
Temperatures will range from the 20s to 30s through the weekend,
falling into the teens and 20s for early next week. A chance of
snow over the western Brooks Range early next week.

Coastal Hazard Potential Days 3 and 4...None.
