Discussion
Models... Surface initialized well against the 25 18z analysis.

They are in good agreement out to around 84 hours before
differences start showing up in the major features. The big
difference being how they handle the upper level low that will
move moving south over the west coast. Over the arctic persistent
westerly flow will continue, but by Friday afternoon models
diverge on how the ridge builds north over the beaufort sea.

Aloft... At 500 hpa... A 521 dam low high in the siberian arctic
will persist with ridging building over the beaufort sea Friday
and Saturday, so westerly to southwesterly flow will persist over
the arctic through the weekend. A 554 dam low over the bering
strait will continue to dive to the southeast to be over king
salmon by Wednesday afternoon, and continues south into the
pacific. A 562 dam low over the northeast pacific will move
northeast into british columbia by Wednesday evening. Ridging from
a 597 dam high over the north pacific will build north over the
chukchi sea tonight, then rotate southeast Wednesday night with
the axis extending from amchitka island to nuiqsut by Thursday
morning, then extending north along 150w. By Friday morning the
ridge will rotate to lie over the alaska peninsula to lake iliamna
to anchorage to demarcation point and north over the beaufort
sea. A 553 dam low over the sea of ohkotsk will move northeast
into siberia, then east of the chukotsk peninsula by Thursday
evening, then over st lawrence island by Friday evening at 558 dam
with troughing extending from unimak island north to st lawrence
island then over 170w. At 850 hpa... No significant change in
temperatures into Wednesday, then a warming trend over the
interior that will continue into the weekend.

Surface... A broad area of low pressure with a 1010 mb low over
the upper yukon flats, 1010 mb low over kotzebue sound, and a 1012
mb low over the southwest mainland this afternoon. A cold front
lies from kotzebue to russian mission to togiak this afternoon and
will move southeast to lie from sleetmute southeast over kodiak
island by Wednesday morning. The thermal trough which lies over
the upper yukon flats will slide south to the upper tanana valley
and north slopes of the alaska range by Wednesday morning. A ridge
is continuing to build over the eastern bering sea, chukchi sea,
and arctic coast with a 1020 mb high over the gulf of anadyr, a
1020 mb high over the chukchi sea, and a 1018 mb high over
mackenzie bay. By Thursday morning the ridging will lie from the
eastern bering sea to the bering strait to barrow and east with a
1021 mb high near st matthew island, a 1021 mb high over barrow,
and a 1020 mb high north of mackenzie bay. Wednesday night a cold
front will move to the bering strait then stall over the area
Thursday as it decays. The high over barrow will move east to be
just north of mackenzie bay Thursday morning at 1022 mb. As the
high moves east the thermal trough will slide a bit north to lie
from northway to livengood, then southwest to mcgrath.

Arctic coast and brooks range... A weather front moving through
the area will be east of the area by Wednesday morning. Expect
some clearing skies Wednesday from west to east across the area as
mainly offshore flow develops with the high moving east.

Temperatures will generally be in the mid 40s to mid 50s on the
coast and 50s to lower 60s inland Wednesday, then rising Thursday
with coastal areas rising into the 50s to lower 60s, and inland
areas reaching into the 70s. The warmer temperatures will last
into the weekend. Winds turning east to southeast at 5 to 20 mph
for most areas the remainder of the week.

West coast and western interior... Cloud to mostly cloudy
conditions will continue over the coastal areas this week with
periods of showers. There will be a little break Wednesday with
some clearing before the next system moves to the eastern bering
sea bringing another round of showers to the area. For the inland
areas clearing early Thursday will last into Friday, then
increased clouds and a chance of showers. Temperatures quite a
bit warmer on Thursday after it clears out, then cooling back down
a bit with the increased cloudiness. Winds northwest at 5 to 15
mph for most areas, with 20 to 30 mph winds on some of the outer
capes. As the next system moves to the bering strait Thursday,
winds will snap around to southeast to south with 10 to 20 mph
winds over the coast, and 15 to 30 mph winds on the capes. Winds
inland will generally be less than 10 mph. Heaviest rainfall has
ended over the upper noatak and upper kobuk basins and streams
remain high so advisory will continue into the evening then be
reevaluated.

Central and eastern interior... Isolated to scattered showers
continue across the area through Wednesday afternoon then
clearing. Rainfall amounts generally less than one tenth inch,
some locations in the alaska range could see up to one quarter
inch. Isolated thunderstorms south of chicken this evening, then
over most of the area on Wednesday. Clearing across the central
and eastern interior Thursday with warming temperatures that will
last through the weekend. Central interior will see some increased
clouds on Friday with a chance of showers as front pushes over
the west coast. Winds will generally be light, but they pick up to
10 to 20 mph along the alcan border north of eagle and over the
upper yukon flats Wednesday night and Thursday.

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

Fire weather Pretty quiet with isolated to scattered showers
through Wednesday evening, then a drying trend for all the
interior areas. Isolated thunderstorms over the eastern and
southeastern interior Wednesday with the thermal trough over the
area, then over the upper tanana valley along the north slopes of
the alaska range to the upper kuskokwim and middle yukon south of
galena Thursday. High pressure building in will bring drier and
warmer conditions to the central and eastern interior, but no red
flag conditions expected.

Hydrology Heaviest rainfall has ended over the upper noatak
and upper kobuk basins and streams remain high so advisory will
continue into the evening then be reevaluated. Significant rises
in the middle koyukuk river near bettles with this last rain
event, but everything remains well within banks, so no issues.

Afg watches warnings advisories
Small craft advisory for pkz210-pkz220-pkz225.

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.
