southcentral and southwest alaska forecast discussion
national weather service anchorage ak
416 am akdt Wed mar 22 2017

Analysis and upper levels
A blocking ridge persists over the bering while an upper low is
developing over southcentral alaska. The combination of these two
is allowing for outflow winds over the southern mainland and is
also keeping much of the area void of cloud cover and precip.

West of the ridge, a weak front is pushing through the western
bering as it diminishes.

Model discussion
Models remain in decent agreement over the next couple days and
forecast confidence is generally high.

Aviation
Panc...VFR conditions and light winds will persist.

Short term forecast southcentral alaska (days 1 and 2)
The weather will mostly remain the same for southcentral alaska through
Thursday as the region remains in a dry offshore flow with local
gap winds. Scattered snow showers will impact the north gulf coast
east of prince william sound and as far north as the copper
basin. Mostly clear skies should persist west of the chugach,
kenai and talkeetna mountains the next few days. Expect continued
significantly below average night time temperatures with day time
temperatures remaining a little below normal as well.

Short term forecast southwest alaska (days 1 and 2)
Little change in the pattern is expected through Friday morning as
the region remains locked in dry north-northwest flow on the
eastern periphery of the bering ridge. This will mean a
continuation of cold, dry, and sunny conditions across most of the
area. A weak upper level wave dropping down from the northwest on
Thursday will provide a slight boost to the diurnally driven
gusty winds on Thursday afternoon and also reintroduce some
modest cloud cover to interior portions of the southwest
mainland. A few flurries can also not be ruled out across the
kuskokwim valley, though the firmly entrenched dry air mass in
place will keep any precipitation on the very light side.

Short term forecast bering sea/aleutians (days 1 and 2)
The powerful blocking high will keep benign partly sunny
conditions in place over the eastern half of the bering through
the end of the work week. The shortwave dropping through the
southwest mainland will also serve to enhance gap winds over the
coastal waters on the south side of the alaska peninsula on
Thursday. A weak, decaying frontal boundary will keep rainy
conditions over the western bering into Thursday. A much stronger
front associated with a deep north pacific low will spread gale
force winds and steadier rain over the western/central aleutians
beginning late Thursday.

Long term forecast (days 3 through 7)
The persistent sunny, dry, and cold pattern across the mainland
will remain in place through the start of the weekend. However,
starting Sunday and continuing into next week confidence is
growing that a change in the overall weather pattern is on the
horizon for the mainland. All global models have now caught onto
a solution where an upper low moves across southern alaska from
the north and retrogrades to somewhere in the vicinity of
southwest alaska or kodiak island for at least the first half of
next week. This will result in a switch to warmer southeasterly
flow across most of mainland alaska, and also usher in chances for
snow - especially to the coastal areas but depending on elusive
details possibly interior locations as well. Bottom line: stay
tuned, change appears to be coming.

Afc watches/warnings/advisories

Marine... None.

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.
