Discussion Long wave troughing remains centered over mainland
alaska, with the 20 12z showing the trough pattern consisting of
a 538 dm low located around 30 miles northwest of anvik. A short
wave was rotating around the southern periphery of this low,
located at 12z in the western gulf of alaska. A second low with a
534 dm low center was located near the high arctic around 78.4n
167.5w. Upper level ridging was located over the western
aleutians, which extends north through the western bering and
eastern siberia. A 565 dm low was located just south of the
kamchatka peninsula. At the surface, a 997 mb low was located 180
miles south southeast of kodiak. A surface ridge of high pressure
extends from the north pacific into the bering sea, extending
through northwest alaska and through the beaufort sea. A weak 1002
mb low pressure system was skirting across the siberian arctic
coast, around 145 miles southwest of wrangel island.

The 12z deterministic models are in good agreement on the overall
pattern through the upcoming week, with long wave troughing
expected to persist over the state. Upper low near anvik will
drop south across the alaska peninsula this evening, and into the
gulf late tonight. A short wave rounding the southern side of the
high arctic upper low will move through the siberian arctic coast
today, to cross the chukchi sea tonight to move over the western
ak arctic coast Monday morning. A second piece of energy will move
out of the chukotsk peninsua Monday night to the western seward
peninsula Tuesday morning. These two features will effectively
work to form an upper trough over the western third of the state
by Tuesday, while squashing the upper ridging over the bering
sea. Additional short waves dropping down the backside of this
newly formed trough from eastern siberia, combined with the upper
low south of the kamchatka peninsula moving east across the
aleutian chain toward bristol bay, will further act to deepen this
trough Wednesday. Upper level ridging becomes restablished over
the western bering and east siberia Wednesday night.

North slope brooks range: a weak disturbance will move north into
the eastern brooks range tonight, bringing a round of rain to this
region as well as the eastern arctic coast. Snow levels will
remain high around 5000 feet. Easterly flow will continue over the
central and eastern arctic coast with a 1016 mb area of high
pressure over the eastern beaufort sea, which will drift off to
the northeast north of banks island by Tuesday. This will promote
periods of fog and stratus to persist through tonight, before
winds just off the deck turn more offshore for Monday. A weak
surface low will pass just south of wrangel island this afternoon
and move out into the chukchi sea tonight, then slowly drift to be
located near CAPE lisburne by late Monday night. A weather front
will extend in front and to the south of this low, which will
bring another round of rain to the western arctic coast and
western brooks range late tonight into Monday. The front will
continue to advance east through the eastern half of the north
slope and brooks range, to bring rain to this region by Tuesday
afternoon. Showers will wrap around the low circulation over the
western arctic coast and western brooks range on Tuesday, with
snow levels falling to around 2500 feet, and down to around 3000
to 3500 feet on Wednesday for the central brooks range.

West coast west interior: ridge of high pressure will weaken over
the west coast tonight, as a weak surface low will pass just
south of wrangel island this afternoon and move out into the
chukchi sea tonight, then slowly drift to be located near cape
lisburne by late Monday night. A weather front will extend in
front and to the south of this low, which will bring another round
of rain to the chukchi sea coast and western seward peninsula late
tonight into Monday, pushing through the western interior Monday
night into Tuesday. Lighter rain showers are expected south of
the seward peninsula. Showers will wrap around the low circulation
over the chuckchi sea coast and western brooks range on Tuesday.

Southerly winds to around 25 knots will accompany the frontal
system through the bering and chukchi sea tonight into Monday
morning, followed by gusty northwest winds to around 30 knots that
will develop on the backside of the low pressure system Monday
evening into Tuesday. The strength of the wind and fetch looks
favorable enough for high surf and potential beach erosion for
shishmaref developing Monday night and continuing through
Tuesday, before winds turn to the north and diminish Tuesday

Central and east interior: scattered showers are expected for
interior alaska through Monday, with the best chances focused
along the alaska range. These showers will be diurnally enhanced,
and isolated afternoon evening thunderstorms will be possible for
the east interior through this evening. A weak disturbance will
move north from the east interior, which will continue to bring rain
to the southeast brooks range, mainly from the dalton highway east
tonight. Rainfall amounts look to be lighter compared to
yesterday, generally up to one half inch or less with the heaviest
amounts around arctic village. A weakening weather front moves
into the central interior Tuesday, helping to refocus an area of
light rain or showers here, to push into the east interior by
Tuesday night.

Coastal hazard potential days 3 and 4... Low pressure will move
from CAPE lisburne Tuesday to the eastern beaufort sea on
Wednesday. Northerly winds on the backside of this low could
produce high surf over the central arctic coast by Thursday.

Fire weather No concerns at this time. Slight chance of
thunderstorms this afternoon and evening from fairbanks north and
east. Chance of wetting rain remains relatively high in the upper
yukon flats and eastern brooks range. Some drying for the western
interior on Monday, but relative humidity values remain high and
will generally be above 40 percent. Sustained winds less than 15

These have not been checked for accuracy and in many cases have not even been read by anyone associated with 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 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.
