Blizzard Warning 26, NWS Fairbanks, AK

Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
603 AM AKDT Thu Mar 19 2026

.SYNOPSIS...
Looking at the next few days, the interaction between the Eastern
Siberian high pressure and the low pressure digging down into the
Gulf of Alaska is supporting strong winds and blowing snow on the
West Coast and Eastern Arctic Coast. While these conditions are
expected to subside between this morning and Friday morning, they
could reappear on the North Slope as easterly winds begin
strengthening on Friday. Below average temperatures persist for
most of the state until a pattern change early next week supports
a gradual warming trend across the region.

.KEY WEATHER MESSAGES...
Central and Eastern Interior...

 - Below average temperatures continue for much of the Interior,
   especially in valleys, reaching the 20s to 30s below into the
   weekend.

 - Northeast winds in Interior Valleys are expected to strengthen
   as we approach the weekend, with gusts up to 15 mph and stronger
   gusts at higher elevations.

West Coast and Western Interior...

 - Winter Weather Advisories remain in effect for the Western and
   Central regions of the Seward Peninsula, and the Yukon Delta
   Coast for blowing snow and strong northerly winds with gusts up
   to 40 mph. The products located directly on the coastline are
   scheduled to end Friday morning, while the inland products are
   scheduled to end Thursday evening.

 - Below average temperatures are expected to follow the strong
   northerly winds as many areas could see 20 to 30 degrees below.
   However, 50 below is possible with wind chill.

North Slope and Brooks Range...

 - A Winter Storm Watch is in effect for the Eastern Arctic Coast
   including portions of the Dalton Highway and areas from
   Deadhorse east for light snow and wind gusts as strong as 50
   mph.

 - Mostly clear conditions across the North Slope could last
   through this weekend.

 - Temperatures are likely to increase starting early next week
   following the change in pattern.

.FORECAST ANALYSIS AND DISCUSSION...
For Thursday through Saturday night.
Similar to what we have been observing for most of this week, a
high pressure over Eastern Siberia and the Western Aleutian
Islands remains present. This system has continued to interact
with the low pressure system moving into the Gulf of Alaska. Currently,
a shortwave is supporting periods of light snow and strong winds
for the majority of the West Coast and Eastern Arctic Coast.
Products have been issued for these impacts accordingly.

These high and low pressure systems aloft supporting strong
northerly winds on the West Coast that are expected to weaken as
we approach the weekend. These northerly winds will be followed by
below average temperatures and wind chills as low as 50 below as
the low pressure center continues to move further down into the
Gulf of Alaska. In the Interior Valleys, low temperatures are
expected to remain below average through the weekend until a
pattern change allows gradual warming throughout next week.
Interior Valleys may also see strong northeasterly winds this
weekend with gusts up to 15 mph as the gradient created by the
high and low tightens.

On the North Slope, light snow and strong winds are supported by a
piece of shortwave energy through Saturday morning for the Eastern
Arctic Coast. This event has the potential to evolve into blizzard
conditions, as easterly winds are expected to gradually
strengthen, and will be monitored throughout the week. As the
gradient is likely to weaken this weekend, these strong winds are
expected to weaken as well. Following the weekend, a pattern
change is on the horizon.

.EXTENDED FORECAST DAYS 4-7...
Sunday morning through next Friday morning.

A pattern change is expected towards the end of the weekend and
early next week as the upper level ridge over Eastern Siberia
moves in a northerly direction.

This change in pattern gives Interior Alaska the opportunity to
become slightly windier, allowing mixing and slightly warmer
temperatures into next week. This week could be the last that we
experience extreme cold for this winter.

Coastal Hazard Potential Days 3 and 4...None
