Discussion
Synopsis...

scattered thunderstorm activity across the eastern interior, yukon
flats, and eastern brooks range will be the main threat this
evening as well as Wednesday afternoon and evening. High pressure
will keep much of the central interior and tanana valley including
fairbanks clear of most of the convection, though an isolated
thunderstorms cannot be ruled out. Farther west, a weak low moving
northwest across the seward peninsula will bring scattered showers
and cloudy skies to much of the region. Isolated thunderstorm
activity is again possible across the lower yukon and kuskokwim
valleys, though limited instability will hamper any significant
outbreak potential. A weather front will lift north across the
north slope this evening. Warmer temperatures and southerly winds
are expected along with a chance of showery mixed precipitation.

Aloft 500 mb...

longwave troughing across the eastern bering sea continues to
increase in amplitude, reaching as far as 25s. Ample subtropical
moisture will be pulled north as ridging also amplifies from the
northeast pacific into southeast alaska. Meridional oriented flow
aloft will be occasionally disrupted and a series of shortwaves
track north across the state. Otherwise, the longwave pattern will
remain fairly similar through the weekend.

North slope and brooks range...

a weather front sweeping north across the brooks range to the
north slope will push offshore by late this evening. A southerly
shift in winds along with increasing temperatures and decreasing
cloudiness is expected into early Wednesday. However, by Wednesday
afternoon, an upper level low will move east from siberia as high
pressure builds over the beaufort sea. An inverted trough at the
surface associated with a bering sea low will provide moisture to
the resulting frontal zone. A complicated synoptic interaction
will then ensue through the weekend featuring showery mixed
precipitation, variable winds, and low stratus.

West coast and western interior...

an arctic boundary remains in place across the chukchi and eastern
bering. West of the boundary from point hope to wales to st.

Lawrence island, expect high temperatures near freezing with snow
showers and occasional mixed precipitation. East of this line
expect showers as a low tracks northwest from the seward peninsula
into the chukchi sea. Isolated thunderstorms will be possible
this evening across the lower yukon and kuskokwim valleys as well
as the noatak valley from kiana to noatak. As the low pushes north
into the high chukchi Wednesday, the arctic boundary will creep
eastward supported by siberian high pressure. Cooler high
temperatures are expected across much of the immediate coast
Wednesday and Thursday. The thunderstorm potential will remain
muted through the rest of the week with only a slight chance for
isolated storms across the lower yukon and kuskokwim valleys.

Central and eastern interior...

thunderstorm activity this afternoon and evening will be
concentrated mainly north and east of a line from anaktuvuk pass
to central, to northway. Frequent lightning along with small hail
and gusty winds are likely with these storms, as instability
parameters remain high. Across the central interior and tanana
valley, an isolated thunderstorms cannot be ruled out, but high
pressure and generally more stable conditions will keep
conditions dry and fairly stagnant. Thunderstorm activity will
favor the same areas again Wednesday but will include areas near
and north of fairbanks. A weather front will sweep north across
the alaska range Wednesday evening into early Thursday. Gusty
south winds through alaska range passes are likely during that
time.

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

Fire weather
The fire weather threat this evening will come primarily from
frequent lightning expected north and east of a line from anaktuvuk pass
to central, to northway. Relative humidity will bottom out in the
low 20s this afternoon as temperatures reach the mid 70s. However,
winds will remain light across the region. Shower and thunderstorm
activity will add moisture to the surface and help increase
relative humidity values Wednesday, though temperatures will
generally be 2 to 3 degrees warmer than today. Expect a similar
level of thunderstorm activity to impact the same area Wednesday
with slightly greater extent west to fairbanks. A weather front
expected to sweep north across the alaska range late Wednesday
will cause gusty south winds through passes.

Hydrology
Warming temperatures and increasing freezing levels to 8000 feet
across the central brooks range is causing a rapid snowmelt to
occur. A flood warning has been issued for the koyukuk river at
allakaket due to an expected rise of 4 to 5 feet through Saturday.

The river is already nearing bankfull as of this morning and
rising along with many of the tributaries south of bettles. No
flooding is observed or expected in the bettles area.

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.
