Northern Alaska forecast discussion
National Weather Service Fairbanks Alaska
303 PM akst sun Nov 29 2015
Models in decent agreement through 60 hours. Upper level ridge
that has expanded over far east Russia and will continue to build
through Monday night before being cut off by upper level low in the
Canadian archipelago with extending long wave trough pushing
southwestward into northern Alaska by Tuesday night. This will drop
significantly colder air into northern Alaska at this time. The
long wave trough will stay in position through around the end of
the week. Therefore it is unlikely we will see much on any
organized snowfall over the area.
Surface high pressure in the high Arctic will persist through
the week. A series of low pressure systems will move into the
Bering Sea through the week. This will keep the pressure gradient
fairly tight over northwest Alaska through the week.
Limited snowfall over northern Alaska through the week.
Temperatures should be at or slightly below normal. Winds may be
gusty through the week in northwest Alaska and in the Brooks
Coastal hazard potential days 3 and 4...none

Brisk Wind Advisory for pkz230-pkz235-pkz240-pkz245.
