Cool and rainy conditions will continue for the next couple of
days, with a break in the weather finally coming later this week
for many places in our forecast area. High pressure will move in
Thursday clearing out the persistent cloud cover and rainshowers.

Models agree that high pressure will move into the state from the
southeast Thursday and become the dominant feature on Friday and
last at least through the weekend. There are slight differences
between models, but all are showing the setup of high pressure
occurring with it being the weather driver for the rest of our
forecast period.

Aloft... A closed, occluded low continues to progress north-
northeast over the southwest part of the state. Frontal systems
extend east through the interior and into the yukon and are moving
north with with it while moisture wraps around the backside of
the low, covering the west coast. This low will quickly lose steam
tonight, dissipating into an area of disorganized low pressure.

Another low northeast of the state in the arctic ocean extends
down to the eastern arctic coast and will move through the area
tomorrow. After these lows move through, disorganized zonal flow
will be present over much of the state late Tuesday and Wednesday.

High pressure will then build in from the southeast on Thursday,
becoming the dominant feature in the upper levels by Friday, which
will dictate weather on the surface.

Surface... The area of low pressure currently over norton sound
will begin to fall apart tonight and create a broad area of poorly
defined low pressure stretching from the west coast northeast
across the eastern interior. As this area of low pressure is
replaced by high pressure, a disorganized pattern will be present
on Wednesday. High pressure will then take hold on Thursday and
will be a dominant feature covering most of the forecast area.

Meanwhile on the north slope, high pressure is still holding on in
the arctic ocean, influencing the weather north of the brooks
range. This high is expected to weaken and slide southeast over
the next couple of days, and then be absorbed into the same ridge
that will build over the rest of the forecast area.

Central and eastern interior... More of current conditions for the
next couple of days for the interior. Southwest flow will continue
into early Wednesday, creating conditions for rainshowers and
cloud cover to persist. The exception will be rainshadowed areas
on the north side of the alaska range. The interior will finally
catch a break in the weather later this week. Rainshowers and
cloud cover will move out late Wednesday into Thursday and winds
will switch to as easterly direction, which will allow for drying
in the interior.

Along the alaska range, windy conditions through the passes will
continue into tomorrow morning, as the generally southerly
direction to the winds have been pushing winds is passes to wind
advisory level. Wind advisories remain in place for zones 225,
226, and 224, with winds in that zone isolated to the alaska
highway west of tok. Gusty winds are also expected over areas of
elevated terrain in the rest of the interior through Tuesday. Wind
direction will start to shift Wednesday with the change in weather
pattern, so this will turn off gusty winds.

West coast and western interior... The west coast will see rain
taper off a little bit sooner than the interior, with weather
clearing late Tuesday into early Wednesday. This will only be a
brief reprieve for the west coast as another weak low skirts the
coast beginning Thursday, again bringing rainshowers. Strong winds
will also be present on st. Lawrence island. High pressure in
place should prevent it from pushing inland very much though.

North slope and brooks range... Low ceilings and cloud cover will
continue for the north slope, especially on the eastern north
slope. Later in the week, winds will shift to a more southerly
direction west of utqiagvik, allowing for the possibility of
clearing on the western side of the slope. The eastern side will
continue to see onshore flow from the arctic ocean most of the
week, so don't expect a break in the clouds and fog. Temperatures
are cold enough that any precipitation embedded in this flow could
fall as snow showers.

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

Hydrology River levels along the west coast and interior will
continue to remain high due to continued rainfall in those areas.

An additional 0.50 inches of rainfall in the upper chena basin
will push the chena river to bankfull the next few days. We will
continue to monitor river levels in other drainages as well.

Afg watches warnings advisories
Wind advisory for akz224-akz225-akz226.

Small craft advisory for pkz210-pkz225-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.
