Discussion
A weak low currently over the lower yk delta continues to produce
snow showers over the bering sea and western interior south of
nome with mostly clear skies noted to the north. Mostly cloudy
skies along with flurries and light snow dominate the southern
portions of the central and eastern interior as the mostly clear
conditions of the northern interior give way to clouds and
flurries moving in from the south. Scattered snow showers along
with mostly cloudy skies and light winds will continue along the
north slope through Monday.

The 12z model suite initialized well against the 12 surface
analysis and verified well against the 18z surface analysis.

Model spread is minimal in both the short range and mid range and
is reasonable in the extended range. The model suite displays good
run to run consistency and minimal differences between model
families despite the usually problematic interaction of the
remnants of a typhoon in this case ty and a sea of okhotsk low and
how they merge southeast of the kamchatka peninsula and deepens
as it moves over the western aleutians.

The gfs, ECMWF and canadian models all depict a low currently in
the sea of okhotsk moving southeast and merging with the
remnants of typhoon ty southeast of the kamchatka peninsula
Monday and Tuesday. The now merged lows undergo rapid deepening as
the new low moves east into the western aleutians as a 935 to 940
mb low Tuesday morning. The low moves rapidly east over the
central aleutians Wednesday. A strong front approaches southwest
alaska Wednesday and will bring high end gales to the waters south
of st lawrence island and strong winds to the lower yk delta.

Precipitation associated with the front will likely start off as
snow with 850 mb temperatures around 6 below but may mix with rain
in the lower yk delta. Precipitation is expected to remain snow
over the west coast as well as the western and central interior.

The front weakens rapidly as it moves northeast into the interior
and moves further away from the best support aloft Wednesday
however at this time it appears that the yk delta and western
interior south of galena could pick up 2 to 4 inches of snow as
well as strong winds especially along and near the coast. Given
the track of the storm and the anticipated off shore wind direction
we are not expecting high surf or coastal flood concerns at this
time.

Winds aloft ahead of the storm increase rapidly over the alaska
range Wednesday. A strong mountain wave develops late Tuesday and
Wednesday and will drive the very strong winds at mountain top
level to the surface along the northern foothills of the alaska
range. Wind gusts in excess of 70 mph are possible along the
foothills of the northern alaska range beginning Wednesday
morning. The downslope winds will limit snow accumulations over
the central interior south and east of fairbanks and will limit
snow accumulations over eastern interior south of chicken.

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

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.
