Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
421 AM AKDT Sat Apr 29 2017

.DISCUSSION...

Models in good agreement through 84 hours. Upper level low in the
far western Bering Sea will move eastward across the aleutians
and over brisol bay by sunday afternoon then move into the gulf of
alaska by tuesday morning. A 540 dam high will remain over the
eastern arctic through tuesday.

Surface...A 1030 mb high west of banks island has ridging
extending northwest into the siberian arctic through the weekend.
A 987 mb low will wobble around the western bering before entering
the gulf of alaska on monday and weaken to 995 mb.

Interior...Winds will pick up a little in the Alaska Range
beginning Sat as southerly flow increases slightly. Winds should
remain below advisory level though. Thermal trough from southeast
Alaska will continue to provide sufficient instability along with
an upper level short wave moving north from the Gulf of Alaska to
produce isolated showers over the area through at least the
middle part of next week. Highs in the mid to upper 50s with lows
in the lower 30s through early next week.


FIRE WEATHER...With moist airmass over much of the Interior,
expect that RH values will continue to be for the most apart above
30 percent. Winds will serve to dry out the area a little though
but do not expect any advisories within the next 48 hours.
