Northern Alaska forecast discussion
National Weather Service Fairbanks Alaska
555 am akdt Tuesday Oct 6 2015
models similar through about 60 hours. Upper level ridge extending
up into the interior but losing its structure as the low in the
Bering is crushing it back to the east. The low in the Bering Sea
will eventually drop south into the Gulf of Alaska and develop a
trough over all of northern Alaska by the end of the week. This
will allow the upper level ridge to develop again...albeit for only
a short time...over the eastern interior.
The Arctic front lies somewhere around Barrow to Demarcation
Point and then southeast from there. This is producing some very
light snow showers on the Arctic coast.
The surface low in the Bering Sea and the surface high in the
northern Arctic will continue to produce a strong pressure
gradient over the Northwest Arctic coast and the West Coast
through most of today. The Northwest Arctic coast will see
relatively strong wind that will last into the weekend.
Disagreement in the model to model consistency shows little
confidence in the long range models.
Coastal hazard potential days 3 and 4...none
Small Craft Advisory for pkz215-pkz225-pkz230-pkz235-pkz240.
Gale Warning for pkz200-pkz210-pkz220.
