.DISCUSSION...

Key Weather Impacts by Region:

Central and Eastern Interior...
A brief chance for snow shower possible this afternoon, but the
main front shifts east Sunday night. Winter Weather Advisories are
still in effect around the Central Interior for accumulating
snowfall, to begin across the Interior Sunday night and continue
through Monday. This will impact Monday morning and evening
commutes. 4 to 6 inches of snow possible for the Fairbanks metro
area, up to 8 inches over parts of the N Interior along the Dalton
Highway. A strong cold front moves south of the Brooks Range
Monday afternoon into Monday night, bringing north gap winds
through the Brooks Range and blowing and drifting snow. After the
snow, cold high pressure then settles in Tuesday and beyond with
plummeting temps and drier weather.

West Coast and Western Interior...
Winter weather advisories remain in effect for the Western
Interior zones. Also Winter Storm Warnings for parts of
the southern Brooks range where up to 10 inches are possible,
but elsewhere, looking at a solid swath of 4 to 8 inches. Snow
should begin to taper off late Mon afternoon. Gale force north
winds will move across the Bering Strait coast as a cold front
drops south Monday afternoon and overnight with blowing snow.

North Slope and Brooks Range...
Snow will begin to spread across the Brooks Range as a strong
cold front moves eastward. This front will support significant
north winds and blowing snow through the Brooks Range passes
Monday and Monday night. Passes along the Dalton Highway will see
blowing and drifting snow. Total snow accumulations of up to 3
inches. Winds gusting as high as 45 mph will reduce visibility to
one half mile or less at times. Not much precip along the north
slope and precip in the Brooks Range will taper off by Mon
evening.

Extended Forecast Days 4-7...
An arctic trough settles in Tuesday through Friday with rapidly
dropping temps as skies clear out and arctic high pressure moves
over the N Mainland. A weak front will clip the Arctic mid to late
week, otherwise, very quiet weather looks to settle in with the
main storyline being a return to colder than normal temps.

Analysis and Forecast/Confidence Discussion...
Current Upper level pattern showing a strong 570+ dam ridge
in the N Pacific. An open wave aloft is currently over Saint
Lawrence Island, then the shortwave will push inland on Monday.
This low will be the main snow maker for the Western and Central
Interior. Strong ridging will build over the Bering Sea Monday
and hold through much of the week. Colder air will begin to filter
over the much of the state Tuesday through Thursday.

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