Discussion
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.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
