Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
337 PM AKDT Thu Apr 27 2017

Models fairly consistent with synoptic features through about 48
hours. The ECMWF is more ambitious with extending the upper level
ridge from northwest Canada to Northwest Arctic Coast through
Saturday while the other models pull it back prior to that.
Upper high north of Oliktok on Friday will remain nearly constant
but retreating northward on Saturday.

Weak surface low near Sand Point will weaken to just a trough by 
later Thursday night. Large 968 low in the Western Bering will
have little to no effect on the weather in Northern Alaska as its
energy dives into the Gulf of Alaska.

Isolated showers over the Central Interior will persist through
Friday with the washed out occluded front and the thermal trough 
over the southeastern Interior.

As the low continues to weaken on the Aleutians and the High moves
eastward in the Arctic, the gradient will continue to weaken over
the northwest Arctic Coast.


.FIRE WEATHER...Overall RH values over 30 percent with moist
intrusion of the airmass into the southeastern Interior. Normal
mixing winds over the Interior will subside later this evening.


Brisk Wind Advisory for PKZ230.
