Discussion
Models... Continue in good agreement out to around 60 hours before
differences start showing up in the major features. Surface
initialized well against the 28 06z analysis with main features
within a couple millibars, and locations were very reasonable. The
big difference being how they handle the upper level low that
will move over the western arctic early Saturday.

Aloft... At 500 hpa... A ridge extends from a 597 dam center south
of shemya over the alaska peninsula to anchorage to kuparuk this
morning with a 564 dam center over the upper yukon flats. By this
evening the ridge will be south of the alaska peninsula to prince
william sound, then north over the alcan border with ridging
extending north over 145w. The ridge will remain stationary into
Saturday, when the center will start drifting back to the
southwest and a 566 dam center will be over delta junction Sunday
morning then drift southeast through Monday morning over the upper
tanana valley. A 552 dam low 700 south of prince william sound
will move northeast to 100 nm west of sitka by Sunday morning. A
548 dam low is moving over the western chukchi sea this morning,
and will move north along 170w through Saturday morning, then is
absorbed by a 532 dam low that will be spinning off from the 523
dam low that has been high in the siberian arctic for several
days. Troughing lies over the west coast from point lay to
southern kodiak island and will weaken through the day. A 556 dam
low is moving south of the gulf of anadyr this morning and will
be over st matthew island this afternoon, then over bristol bay
by early Saturday morning before crossing over the alaska
peninsula and merging with the low in the northeast pacific. The
low will enhance the troughing over the west coast tonight. At
850 hpa... A slight warming trend over the eastern half of the
state as temperatures rise to +10 to +13 celsius and persist
through most of the weekend. Out west temperatures not changing
much the next few days. A cold front will move to the northwest
coast Sunday morning with the zero isotherm pushing south to lie
from nuiqsut to CAPE lisburne Sunday afternoon.

Surface... A 1019 mb high over the coast of banks island will
slowly break down through Sunday morning. A broad area of low
pressure over mainland alaska with the thermal trough over the
upper tanana valley and along the alaska range. A 994 mb low
moving into the western chukchi sea this morning will move north
along 170w through Sunday. The associated weather front that is
over the west coast will continue to stretch out over the area and
eventually dissipate over the western interior early Sunday.

Ridging over the gulf of alaska coast with a 1017 mb high over
prince william sound will expand over the southwest mainland
tonight and merge with ridging over the eastern bering sea, then
expand into the central interior Saturday night. Ridging over
siberia will expand east over the chukotsk peninsula Saturday, and
over the arctic coast Sunday. Main area of precipitation today
will be southwest of a line from dawson yt to point lay with the
heaviest concentration of showers west of tanana along the weather
front. Expect isolated thunderstorms and showers to the east of
tanana.

Arctic coast and brooks range... Stratus and fog just offshore from
barrow east. Some has moved onshore at deadhorse and other areas
will see it move onshore for at least a short period this
morning, then some higher clouds the remainder of the day. The
stratus deck looks pretty extensive in size on satellite imagery,
and could move further onshore and stay along the coast with the
persistent easterly flow, but at this time expect it to move back
offshore by late morning. East to southeast winds 10 to 20 mph in
the coastal areas with lighter winds inland. Temperatures will be
warming the next couple days with most coastal areas in the 60s,
and even some low 70s around deadhorse today after they clear
out. Cold front will move to the northwest coast Sunday with a
sharp cooling trend along the northwest and central arctic coast
that will drop temperatures significantly.

West coast and western interior... Front will be hanging over the
area as it decays. Mostly cloudy conditions with scattered
showers and isolated thunderstorms will continue through Saturday.

No significant rain expected. Some patchy fog, especially
overnight and early morning in the coastal areas. Winds southeast
to south at 10 to 20 mph, gusts to 30 mph on the outer capes. No
change in temperatures.

Central and eastern interior... Mostly cloudy with isolated
thunderstorms and showers mainly west and south of beaver. Winds
will be light and variable. Increasing winds in alaska range
passes today as gap winds develop with gusts to 45 mph that will
persist into Saturday morning. Temperatures slightly cooler but
highs will be in the 70s and lows in the 50s through the weekend.

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

Fire weather Isolated thunderstorm activity south of a line
from dawson yt to point lay today. Wetting rains possible in the
lower yukon delta. Winds increasing in alaska range passes with
gust to around 45 mph possible, but relative humidity values
remain above 30 percent for all areas, with no change expected.

Hydrology No concerns at this time.

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.
