Discussion
Models... Short term continues to be in very good agreement, and
run to run has be very consistent. Extended periods are another
problem all together. There is little agreement in the extended
solutions. Surface analysis at 15 18z was very similar to the
15 12z solutions. Will be using the SREF for precipitation again
today to give the areas with precipitation the higher
probabilities that it generates.

Aloft... At 500 hpa... Strong south flow continues over the state
tonight, but will turn from the southeast as the ridging to the
east pushes west over the state tonight, then moves north with the
ridge axis lying over the eastern brooks range, then southwest
over kuskokwim bay by Tuesday afternoon. The ridge will continue
to swing north Wednesday, and by afternoon it will lie over the
central arctic, then southwest over the chukchi sea. Troughing
lies to the west and north of the ridge with a 507 dam low over
the chukotsk peninsula that will weaken and merge with a 497 dam
low over the sea of okhotsk. A 511 dam low in the NE pacific will
move northwest over kodiak island by Tuesday afternoon at 513 dam,
then over bristol bay at 518 dam Wednesday morning. A 518 dam low
will develop over the western interior Wednesday morning and move
over the northwest arctic coast by Thursday morning at 515 dam.

At 850 hpa... Temperatures around zero lingering over the alcan
border, and even sneaking into the central interior tonight will
spread southwest with the zero isotherm lying from barter island
to mcgrath Tuesday afternoon with most areas to the southeast of
it above zero. Patches of above zero temperatures will linger over
the interior and slowly cool through Thursday morning. On the west
coast the -10 isotherm is just offshore and will move over the
west coast Wednesday night as the cooling trend over the state
continues.

Surface... Weak high pressure over the state with a 1003 mb center
over the central interior that will slowly move northeast to be
over arctic village Tuesday morning at 1010 mb, then merges with
the ridging over the eastern arctic that extends south from a 1030
mb high over the north pole. A 982 mb low in the bering strait
that will move to wrangel island by Tue afternoon, then NW into
the siberia arctic. Weak troughing remains over the arctic coast
and nearshore waters, while a 998 mb low in mackenzie bay will
move E and dissipate in canada. A 978 mb low in the northeast
pacific will move to kodiak island by Tue evening, then over the
western interior to the northwest arctic coast Wed evening at 993
mb. A 1004 mb high will develop over the yukon territory Thursday.

Arctic coast and brooks range... Some lower clouds over the
northwest coast associated with the low that will be moving to
wrangel island. No signs of low status over the eastern arctic
coast looking at the npp viirs sport 24 hour microphysics rgb at
15 2101z. Winds generally less than 10 mph for a change.

Temperatures may warm a bit overnight, then cooling through the
weekend. Some light snow moving to the brooks range Tuesday
evening and over the coast by Wednesday morning.

West coast and western interior... Mostly cloudy across the area
with some flurries or light snow and a slight chance of freezing
drizzle in the western interior tonight. High pressure moving over
the nearshore waters will bring some clearing late Wednesday as
the low moves north. Winds continue to diminish tonight, and most
coastal areas will have winds less than 15 mph by morning. Inland
winds will remain light and variable. Temperatures will slowly
cool.

Central and eastern interior... Mostly cloudy. A flurry possible
around the interior, with some light snow in the upper tanana
valley. There will be a slight chance of freezing drizzle again
tonight as a patch of warm air moves into the interior with the
next front. Winds gusty in the alaska range, but generally less
than 40 mph. The remainder of the area will have light and
variable winds. Temperatures will continue on the warm side
through Thursday, then cooling through the weekend.

Coastal hazards for days 3 and 4... None.

Extended forecast for days 4 to 7... Models continue to diverge
with little agreement over our forecast area. We can expect
temperatures will be falling, with no significant snow.

Afg watches warnings advisories
Heavy freezing spray warning for pkz210.

Small craft advisory for pkz210.

Brisk wind advisory for pkz215-pkz220-pkz225.

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.
