showers in the Brooks Range through Tuesday. An arctic trough
remaining in place over the west coast, will keep the Interior
cool and cloudy with a chance of precip through Thursday.

.DISCUSSION...
Upper Levels and Analysis...Troughing will persist over the State
through mid week keeping the Interior cool and cloudy along with
shortwaves moving northward across the Interior that will enhance
rain/snow shower activity through Wednesday. An upper low will
develop in the western Bering Sea late Wednesday into Thursday
then track south and move across the Aleutians Friday into
Saturday. Weak ridging and southerly flow will develop over the
Interior next weekend. A strong upper low will move into the Gulf
from the south late Sunday into Monday.

Central and Eastern Interior...
Troughing aloft will keep the Interior cool and on the cloudy
side through mid week. Weak shortwaves will propagate to the north
producing spotty rain/snow showers through Wednesday. Snow level
around 2000 feet. Light amounts of accumulations expected at these
levels. Most of the shower activity will be confined to the
Alaska Range and north and east of Fairbanks. Highs in the mid to
upper 40s through Wednesday. Highs in the 30s over higher
terrain. Lows in the mid 20s to mid 30s.

West Coast and Western Interior...
The pressure gradient remains tight over the west coast and
will continue to see gusty northeastly winds through the Bering
Strait and over the coast around 15 to 30 mph. Upper low dropping
down over the area on Monday will bring some showers to the W
Interior and inland areas on Monday and Tuesday. Highs in the low
40s over much the coast through Thursday.

North Slope and Brooks Range...
Snow showers will continue over the Brooks Range today. Snow
accumulations of 1 to 2 inches is possible with the continued
snow shower activity. Shower activity will diminish some on
Wednesday. The north slope will continue to see areas of stratus
and Fog. Highs in the upper 30s near the coast and colder in the
Brooks Range.

Extended Forecast Days 4-7...
An Upper low is progged to remain over the west coast through
Thursday, while the Interior remains cloudy and cool with the
threat of Showers through at least Thursday. An upper level low
develops over the western Bering Sea late Wednesday into Thursday
and tracks to the south on Friday then moves along the Aleutians
