Synopsis
Snow and blowing snow over the eastern interior will end this
evening, except at barter island where winds and blowing snow
will develop this evening and last until midnight. The western
arctic coast and zone 213 will see gusty winds and blowing snow
this evening as well.

Tonight will see a turn to colder conditions which will drop temps
closer to normal, but another weather system pushing north late on
wed will bring a return to windy conditions and snow and blowing
snow for the northern and western interior and west coast late wed
into late thu, while the SE interior sees a returns to chinook
winds and much warmer than normal conditions, and the arctic stays
just above normal. These conditions expected through the weekend.

Aloft...

the long wave pattern with the trough over the bering, N pacific
and WRN gulf of ak with ridge over WRN canada is retrograding a
bit over the next few days with the ridge building west over
mainland ak by wed, persisting there into this weekend, then
progressing next week back to a ridge positions over NW canada
next week wed.

A short wave trough now over NE ak will move north tonight
allowing the ridge to rebound.

Several strong short waves will push from the gulf of alaska
north over western ak on late Wed and late Thu bringing stormy
weather to western ak late Wed into fri.

Surface...

a 998 mb low in mackenzie bay will move east tonight. A cold front
from this low to arctic village to northway will move east of the
alcan border this evening. This low and front is causing snow and
blowing snow in NE ak that will end this evening. This will also cause
snow and blowing snow at barter island this evening, but since
there is front hanging southwest of the low, this is keeping
winds at barter island from getting as strong as previously
expected.

A 990 mb low 100 nm north of wrangel island will move to 350 nm
north of point barrow by 4pm wed, and to 600 nm north of demarcation
point by 3pm wed. A cold front extending from this low to the
west coast of alaska will move east to prudhoe bay to the yk delta
by 4am wed, to arctic village o the yk delta by 4pm wed, and then
remain stationary into Thu night or fri. SW winds 25kt along this
front from the bering strait to point hope care now causing
blowing snow that will spread NE with the front tonight, and
decrease west of the front. Winds will turn NE along the front on
wed over the interior and west coast and increase Wed night. The
front will serve as an over running boundary as several systems
moves north out of the gulf of alaska. Expect 4 inches of snow
along and west of the front, along with blowing snow and reduced
visibility. May need to issue wwa for Wed night into Thu night for
zones 214 215 216 218 and 219 but will look over tonight and wed.

Any precip SE of this front will likely fall as rain, which a
chance of freezing rain at night.

A low in the gulf of alaska will move to bristol bay Wed night
and there persist into thu. This will push moisture up and over
the cold frontal boundary late Wed and thu. This will also
increase the gradient causing S winds to increase across the
alaska range Wed night, and NE winds to increase across the west
coast, western interior, and brooks range.

A second low will follow it from the gulf of alaska into bristol
bay on Fri causing more of the same.

Looks like windy, wet and warmer than normal for west coast, wrn
interior and most of the northern slope this weekend into next
week, while the ERN interior stays much warmer than normal with
brief rain snow.

Discussion
Models initialize well aloft and verify well at the surface at
18z. Models show similar solutions in most fields through fri,
expecting the precip field where the NAM has slightly higher
amounts. Will use a blend of the NAM and GFS precip fields for
areal coverage and amounts.

Coastal hazard potential days 3 and 4...

strong weather system moving north over the bering sea next mon
and Tue could bring SW gales to the west coast. Very uncertain at
this time, but this will need to be watched.

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.
