Northern Alaska forecast discussion
National Weather Service Fairbanks Alaska
413 PM akdt Monday Jul 28 2014
the high centered west of Barrow will remain nearly stationary
tonight...then move northeast Tuesday and southeast Wednesday be north of
Prudhoe Bay at 4pm Wednesday. The models bring winds up nearly to
brisk wind behind this high...but we expect just local 25 or 30
knots from it in the coastal zones(that is...near cape lisburne).
The stronger winds west of the high center are due to a weak
weather front over the east siberian sea that sea will move into
the northern Chukchi Sea Wednesday. The front moves east faster
than the high center.
In the interior on the other hand...the models have the pressure
gradient over the Brooks range increasing as well. Its already
wind through the passes...and gusts around 30 miles per hour are possible
particularly Tuesday night.
The remnants of our westerly regime will be clearing out over
the central and western interior tonight and Tuesday. Some showers
will persist over the southeast interior at least...with some
slight potential for easterly waves as the low aloft over the
southern Gulf of Alaska moves into the northeast Gulf. Expect
a modest surface ridge to develop over the interior...which
combined with lower surface pressure over the northern Gulf
will give some modest gap flow through Alaska Range passes as
Coastal hazard potential days 3 and 4...none.
we may see 30 percent and 25 miles per hour in zone 218 on Tuesday...but no
red flag due to fuel condition.
