The current upper air pattern features a ridge that has persisted
over northern Alaska the past few days. Currently this ridge sits
along a Tanana to Northway axis. The ridge will begin to weaken
tonight in response to a shortwave moving up along the west side
of the ridge. This weakening will only be temporary as the ridge
will build back along the same general orientation late in the
workweek. A 510 dm low a 500 mb currently sits just east of Adak
and will remain quasi-stationary until Thursday. At the surface, a
low currently centered along 80 N north of Barter Island. A front
stretches southwest from the low to Point lay. This front will
move eastward tonight. A 1024 mb high sits in the Chukchi Sea
north of the Chukotsk Peninsula.
North Slope: The past few mornings we have seen dense fog all
along the Arctic Coast. With the aforementioned front moving east
current thinking is that any dense fog tonight and tomorrow
morning will be limited to areas from Deadhorse east. Suomi NPP
VIIRS shows a large area of stratus behind the front, so as the
front spreads eastward cloud cover will increase. There will also
be some flurries tonight and tomorrow for areas behind the front,
along with some areas of fog.
Central and Eastern Interior: It currently looks like today will
be the warmest day of the week for most of the Interior. A cooling
trend will begin tomorrow. A shortwave will move through the
Interior tonight and tomorrow morning bringing along with it some
scattered rain and/or snow showers. Any precipitation that does
fall will be relatively light and for most places will only fall
right as the shortwave is passing through. Cloud cover will also
increase tonight across most of the Interior, with mostly cloudy
skies persisting for much of the remainder of the workweek.
Southerly winds with gusts of 35 to 40 mph are expected from late
Tuesday morning into Tuesday evening in and near Alaska Range
West Coast and Western Interior: A tight pressures gradient is
bringing northeasterly winds with gusts of around 45 mph to St.
Lawrence Island. This will persist through early Wednesday.
Scattered rain and/or snow showers are expected Tuesday and
Wednesday for much of the west coast and western interior south of
the Bering Strait. Chances for showers will decrease on Thursday
for the western interior but will remain for the west coast.
Cloud cover will increase tonight across the Interior with mostly
cloudy skies persisting for the remainder of the workweek for most
locations. Monday will likely be the warmest day of the week for
most Interior locations. Temperatures on Tuesday will be generally
cooler with higher minimum relative humidity values. Southerly
winds with gusts of 35 to 40 mph are expected from late Tuesday
morning into Tuesday evening in and near Alaska Range passes.
