Marine Weather and Tides
Wainwright, AK

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

northern alaska forecast discussion... Corrected
national weather service fairbanks ak
1255 pm akdt Sun jun 24 2018

Discussion
Seasonable weather pattern continues over much of northern alaska.

Aloft at 500 mb, a low centered over the western bering sea will
continue to weaken and drift to the south and west as another
upper level low drops south out of the high arctic and moves south
over siberia early next week. A weak ridge currently over the
yukon and eastern alaska will remain in place through the middle
of next week as weak shortwave trough move north and northwest
into the interior. Winds aloft are expected to remain light
through the period
on the surface a 1020 mb ridge of high pressure currently located
over the mckenzie delta will continue to move to the east while a
trough of low pressure move north and east out of siberia into
the chukchi sea. A 1000 mb low over the central aleutians will
deepen to 992 mb as it moves north into the southern bering sea. A
thermal trough will continue today over the central and eastern
interior and will extend from near fairbanks south and east to
near northway.

On the north slope westerly winds continue to bringVFR conditions
over most of the area with the exception of the eastern north
slope where a weak shortwave continues to produce lower ceilings
and showers. This system will move east tonight as another shortwave
moves north out of the interior and bering strait and will bring
an increase in clouds to the area.

On the northern west coast weak high pressure will drift northeast
and will be and continue to produce mostly clear conditions. A
weak shortwave wrapping around a surface low in the southern
bering sea will bring increased clouds and a chance of rain
showers over the yk delta tonight and Monday.

Over the western interior, the high pressure system drifting
northeast along the coast will continue to limit precipitation
over the northern half of the western interior tonight and into
Monday morning however a shortwave rotating around a low in the
southern bering sea will move into the southern portions of the
western interior Monday and combined with thermal trough which
will expand west into the southern interior tomorrow will produce
scattered showers and isolated thunderstorms especially to the
south of galena. Tuesday will be an active thunderstorm day
especially over the northern portions of the western interior as
a strong thermal trough interacts with a shortwave moving north
over the area destabilizing the atmosphere.

Interior... Isolated thunderstorms will develop this afternoon and
continue into the evening mostly east and south of fairbanks.

This area will expand west on Monday to include portions of the
western interior to the south of galena as well as areas in the
central brooks range. Tuesday will likely be an active thunderstorm
day over the central and eastern interior especially along a
sharp thermal trough from near chicken northwest to fairbanks. The
thunderstorms along the thermal trough on Tuesday will likely
produce gusty winds, small hail and heavy downpours. High
temperatures will nudge warmer Monday and Tuesday with many
locations in the interior reaching the mid 70s.

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

Model spread is minimal in both the short range and in the mid
range. Model spread increases in the extended range especially on
the track and strength of a low to the east of the pribilof
islands Thursday and Friday of next week.

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

Fire weather
Warmer and drier conditions expected over the interior into the
middle of next week. Isolated thunderstorms will develop this
afternoon and continue into the evening mostly east and south of
fairbanks. This area will expand west on Monday to include
portions of the western interior to the south of galena as well as
areas in the central brooks range. Tuesday will likely be an
active thunderstorm day over the interior especially along a sharp
thermal trough from near chicken northwest to fairbanks and
northwest to ambler. The thunderstorms along the thermal trough on
Tuesday will likely produce gusty winds, small hail and heavy
downpours. High temperatures will remain near normal in the upper
60s and lower 70s today but will nudge warmer Monday and Tuesday
with many locations in the interior reaching the mid 70s. Minimum
rh values will remain in the upper 30s and lower 40s over much of
the interior today and drop into the 30s on Monday and into the
upper 20s and lower 30s on Tuesday especially south and east of
fairbanks and over the yukon flats. Winds will likely be gusty on
Tuesday afternoon and into the evening as the strong thermal
trough strengthens. Will need to monitor the central and eastern
interior Tuesday as temperatures and winds may be flirting with
red flag criteria especially near delta junction. Minimum
relative humidities levels are expected to remain just above red
flag criteria in most areas however values may briefly drop into
the upper and mid 20s near delta junction and in the yukon flats
Tuesday afternoon and evening. In addition isolated to scattered
thunderstorms are expected to develop along the thermal trough
stretching from ambler to fairbanks to near chicken.

Hydrology
Warm temperatures aloft will continue over the brooks range
and combined with recent rainfall will produce significant rises
on rivers draining the brooks range. Current forecast bring both
the additional rises on both the sag and the koyukuk rivers but
keep both rivers below action stage. Water levels are expected to
remain high through early next week. Continue to monitor.

Afg watches warnings advisories
None.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code.

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.
