Discussion
The 12z model suite initialized well against the 12 surface
analysis and verified well against the 18z surface analysis. The
12z model suite continues to be in good agreement with previous
model run output as well a displaying minimal spread between mode
families in the short range as well as the mid range. Model spread
increases significantly by the end of the week.

Aloft at 500 hpa, a longwave trough currently over eastern and
central alaska combined with a 500 hpa ridge currently over the
eastern bering sea will slowly retrograde to the west through the
upcoming week with the upper level trough moving over western
alaska and the upper level ridge moving over the western bering
sea by late in the week. Weak southerly flow develops over eastern
and central alaska by mid week and bringing warmer temperatures
to to areas that have had over three weeks of below normal
temperatures. Temperatures are expected to reach freezing by
around Wednesday or Thursday of next week for the first time in
the month of march in fairbanks. The warmer and moist south to
southeast flow will bring the threat of light snow over the
eastern and central interior by mid week as week overunning flow
develops. Only minor snow accumulations are expected with this
system.

Areas of dense fog continue to move in and out of locations along
the the west coast under stable high pressure and will likely
continue through tonight. Reduced visibilities in blowing snow
will continue today along the north slope but will improve late
tonight as winds diminish.

Afg watches/warnings/advisories
None.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
