Northern Alaska forecast discussion 
National Weather Service Fairbanks Alaska
133 am akdt Thursday Mar 26 2015

Discussion...
tranquil weather pattern to continue over northern Alaska through
the weekend with record or near record warm temperatures expected
over the southern interior Thursday and Friday. Nudged temperature
toward the warmer GFS as the NAM was verifying nearly 10 degrees
cold over the southern interior this evening. Other than the
significant temperature differences between the nam12 and the GFS
the models remain in good agreement through the short term and
exhibit expected amounts of spread in feature strength and
position through the middle term and long. Relied heavily on
inherited temperature forecasts and a blend of the 00z European model (ecmwf)...GFS
and nam12 for quantitative precipitation forecast and pop this forecast package.

Aloft...at 500 hpa...a large amplitude ridge remains locked in
place over western North America stretching north into to the
Yukon and northwest territories while a weak upper level low
currently over Kodiak Island will weaken as it drifts to the west
and northwest. A weak shortwave currently over the southern coast
will continue to move to the northwest. A weak shortwave over
the northwest coast will move north and east and be centered just
west of Barrow Thursday afternoon and will strengthen slightly as
it moves just north of Barrow by Friday morning.

On the surface a 979 low 150 nm south of Kodiak Island will
continue to drift to the the north and northwest today as an
occluded front extending across the Gulf from Kodiak Island to
Valdez to Yakutat this morning will continue to move north into
southern Alaska through the day today. Winds through the Alaska
Range passes continue to increase this morning and are expected to
reach advisory levels in the eastern Alaska Range and sub advisory
levels through the passes in the central and western Alaska
Range passes. The occluded front is expected to pass through the
eastern and central interior today with little or no precipitation with
mild Chinook conditions and record or near record high
temperatures over the southern interior today and Friday. The
front will bring scattered rain and snow showers over the western
interior and West Coast Friday. Expect scattered flurries or snow
showers over the western North Slope this evening and Friday
morning over the central North Slope and Friday night over the
eastern North Slope as weak shortwave moves trough the area.
