Discussion
Aloft, at 500 mb, a 499 dam low is currently over the yukon delta
this morning. The upper low will then persist and weaken over the
yukon delta through Tuesday then pushed back to the north by
another low pressure system. This low over the yukon delta will
continue to produce snow showers for the bering strait and saint
lawrence island through Monday.

At the surface, a 990 mb low currently located near emmonak will
continue to weaken and move south to be located near nunivak
island as a 1000 mb low Monday morning. Weak low pressure will
persist across the north slope through Monday. A 1026 ridge of
high pressure will remain in place over eastern siberia and the
western bering sea.

West coast and western interior: winter weather advisory has been
cancelled as well as the high surf advisory for zone 213. Snow
showers will continue into Monday for saint lawrence island but
winds have diminished some this morning. Snow showers will begin
to taper off by Monday afternoon. A frontal boundary will begin to
push into the southern west coast zones by Tuesday evening.

Central and eastern interior: some mid level clouds moving across
the interior this morning keeping temperatures from bottoming out
in some areas. Clear skies expected Monday morning will drop
temperatures to near zero again. Not much in the way of precip
expected through Monday. Gusty winds are expected to develop
Monday night and Tuesday night along the northern foothills and
passes of the alaska range as winds aloft become southerly and
increase between the upper level low located near nunivak island
and an upper level ridge building over the yukon.

Coastal hazard potential days 3 and 4... None.

Afg watches warnings advisories
Small craft advisory for pkz210.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
