Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
152 AM AKDT Sat Apr 27 2024

.SYNOPSIS...
Isolated to scattered showers continue in the Interior with the
greatest likelihood being in the higher terrain. The West Coast
looks to partially clear from east to west with only a few rain
showers possible. The Beaufort Sea Coast will have some lingering
blowing snow, especially around Deadhorse and Point Thompson, but
conditions will be improving through the day.

.DISCUSSION...

Upper Level Analysis...
A quiet pattern for Northern Alaska continues as there is still
some weak ridging over the Interior, a 516 decameter low southwest
of Kodiak and a weak trough east of Kaktovik. There are a few
shortwaves which spread from Point Hope to Northway but they are
weak.

West Coast and Western Interior...
The weather will be quiet outside of some stray showers in the
higher terrain today. Skies will try to clear making for the
nicest day of the week with temperatures in the upper 30s to near
40 along the coast and around 50 in the Interior. Partly sunny
weather continues through at least Tuesday with little change in
day to day temperatures.

Central and Eastern Interior...
Rinse and repeat with what we had on Friday. A few showers will be
around the Interior, especially in the higher terrain. This will
be the case tomorrow and Monday as well with the greatest chances
being in the Alaska Range and Southeastern Interior. Otherwise,
temperatures will be in the mid to upper 50s today for most of the
Tanana Valley, and mid 40s in the Yukon Valley. Then they do cool
a bit more tomorrow with highs in the low 50s around Fairbanks.

North Slope and Brooks Range...
Some blowing snow still prevails along the coast with visibility
less than a mile at times this morning around Point Thompson.
Winds will remain around 20 to 25 mph with gusts to 35 mph through
tomorrow night, so blowing snow will remain in the area, but the
worst conditions have ended. In the Brooks Range, weather will be
tranquil with partly to mostly sunny skies and highs in the 30-40
degree range into next week.

Extended Forecast for Days 4-7...
There isn`t a whole lot to speak of in the extended. One thing we
are monitoring is the ECMWF and Canadian models have come into
agreement on a low from the Arctic dropping south into the North
Slope Tuesday morning, then along the West Coast on Wednesday.
This could bring a brief shot of much colder air and even a chance
for snow in those areas, but with the GFS not on board, our
confidence in this is not too high yet. Past that, there is a lot
of uncertainty in the models, but the weather looks to remain
mostly quiet through the latter portion of next week.

Coastal Hazard Potential Days 3 and 4...None.


&&

.FIRE WEATHER...
Temperatures will be slightly cooling down this weekend with highs
in the 50s in the Tanana Valley. Minimum Relative Humidity values
look to bottom out around 30 to 40% today and tomorrow then try to
lessen heading into next week. Minimum RH`s may drop back into the
teens and 20s along the Tanana Valley with the lowest being near
Delta Junction. High temperatures during this time may warm back
up a bit to near 60 degrees, but winds will not be a concern as we
are not expecting any strong winds.

&&

.HYDROLOGY...
River and lake ice continues to decay across the Interior. Use
extreme caution if traveling on ice.
