northern alaska forecast discussion
national weather service fairbanks ak
227 pm akdt Mon jun 26 2017

Discussion
Main forecast concerns will be thunderstorm potential and coverage
over the interior, brooks range, and north slope, gap winds near
alaska range passes, and stratus fog issues along the arctic
coast. 26 12z model guidance suite seems to be in good agreement
throughout the forecast period in regards to synoptic pattern and
features.

Aloft... An upper level shortwave over the yukon flats and upper
yukon river valley will move east into the yukon territories
tonight and then will lift northeast over the richardson mountains
and northern british columbia Tuesday into Wednesday. A 533 dam
upper low near atka will merge with an upstream shortwave over the
pribilof islands early Tuesday. This will, in turn, amplify the
downstream ridge over western canada, promoting deep southerly
flow over the entire state by late Tuesday night that will
continue through early Thursday.

Surface... A 1015 mb ridge of high pressure centered over the
beaufort sea will move east tonight and then towards the canadian
archipelago by Wednesday night at 1022 mb. A 991 mb low west of
st matthew island will shift to be over the pribilof islands
Tuesday afternoon and then drift northwest towards the gulf of
anadyr Thursday morning. Meanwhile, a weak low over kamchatka
peninsula will move out into the western bering sea Tuesday night
and then will move east south of the aleutian islands through
late Wednesday. Thermal troughing will develop over the interior
again on Tuesday, and will shift over the brooks range and north
slope for Wednesday.

North slope and brooks range... Easterly surface flow will develop
this evening as the surface high shifts to the east and will
continue through the rest of the week. Periods of fog and stratus
is expected to accompany this easterly flow and at times will see
visibilities drop below one mile. There is a possibility for
isolated thunderstorms Wednesday afternoon and evening over the
brooks range and western arctic coast as a few weak upper level
shortwaves move north around the bering sea low.

West coast and western interior... A shortwave and associated
surface front will continue to lift northward from the low in the
bering sea tonight bringing showers to st lawrence island, norton
sound, and the yk delta. Chances of rain will persist through this
week as disturbances rotate around the bering sea low along the
west coast. Over the western interior, chances for rain showers
will develop Tuesday afternoon and evening with chances for
showers continuing through Thursday morning. There is a potential
Tuesday afternoon and evening for isolated thunderstorms over the
upper kobuk and noatak valleys. Daytime temperatures will be
cooler over the western interior Tuesday and Wednesday with
temperatures in the 60s and lower 70s. For coastal areas, daytime
temperatures will range from the 50s to 60s through Thursday.

Eastern and central interior... Upper level shortwave over the
northeastern interior will continue to be the focus for convection
from livengood to north pole and east this evening. Over 1000
lightning strikes have been recorded since convection developed
this morning. Had to adjust the forecast to include scattered
thunderstorms based current trends. Some of the stronger storms
will have heavy downpours, small hail, and gusty winds. Expecting
convection to dissipate after 10 pm with a few lingering
thunderstorms persisting over the far eastern interior into early
tomorrow morning. A thermal trough will develop over the interior
tomorrow with a chance of showers for most of the interior along
with isolated thunderstorms over an area stretching from indian
mountain to bettles southeast to livengood and fort yukon and over
the fortymile country. The focus for convection will shift
further north into the brooks range for Wednesday afternoon and
evening. Southerly flow will persist over the alaska range and
southern interior with gap winds through alaska range passes this
week. Gap winds will be 15 to 30 mph through Tuesday, increasing
along the parks highway Tuesday evening to 15 ro 25 with gusts to
40 mph. Temperatures will remain in the lower to mid 70s early
this week... Climbing into the mid to upper 70s and lower 80s by
Thursday.

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

Fire weather
Scattered thunderstorms are currently ongoing from fort yukon
south in zone 220 and 224 where over 1000 lightning strikes have
been recorded so far today . As a result a red flag warning for
abundant lightning is in effect until 10 pm this evening.

Thunderstorms across this area will weaken and dissipate later
this evening.

Gap winds through alaska range passes will persist through the
rest of the week. There is some concern regarding the potential of
red flag conditions this evening in zone 226, but it looks like
rh values and winds will fall short of the red flag criteria.

Thermal troughing looks to redevelop for the interior tomorrow
with isolated afternoon evening thunderstorms for zones 217, 218
219, 220 and 224, with the threat of convection shifting north
into the brooks range for Wednesday.

Chances of rain and higher humidity is expected from tomorrow
through the rest of this week for the west interior as weak
disturbances rotate northward from the broad upper low in the
bering sea. Dry weather will persist for the yukon flats and
southeastern brooks range with min rh values between 25 to 35
percent through this week.

Hydrology
Locations along the fortymile river have crested and river levels
are now falling, except at the taylor highway bridge where it is
expected to crest by early evening. For the tanana river, river
levels will crest upstream of fairbanks, while from fairbanks
downstream will see levels rise gradually but remain well below
flood stage.

Afg watches warnings advisories
Red flag warning for akz220.

Small craft advisory for pkz210.
