.FORECAST ANALYSIS AND DISCUSSION...Shortwave energy in a
moist southwest flow aloft will trigger scattered showers and
isolated thunderstorms over the higher terrain of Interior the
next several days. Lightning activity is expected to be minimal
this evening but more than yesterday. Isolated thunderstorm
formation is favored over the Fortymile country and eastern
Alaskan Range. Storms will spread up into the Brooks Range this
weekend. More widespread light rain will occur roughly west of
Huslia-McGrath line later tonight into Sunday. High temperatures
this weekend will be in the 70s except for 60s along the west
coast with the clouds and rain. The Arctic Coast remains colder
with gusty east winds and areas of fog Saturday... but warms into
the 50s again by Sunday.

.FIRE WEATHER...
Temperatures this weekend will remain slightly above normal, with
southwest flow on Saturday bringing stratiform rain over the West
Coast and Western Interior; chances for thunderstorms hang on
across parts of the Interior and even the North Slope. Southwest
flow looks to continue into next week, bringing more rainfall and
cooler temperatures into the Interior. RHs look to remain plenty
wet in these patterns, mainly above 40% with a few readings in the
30-40% range possible across the Upper Tanana Valley each day
through Sunday. Northeast winds will gust to 15 mph across the
Yukon Flats Friday afternoon through Sunday. Southerly gap winds
will gust to 30 mph through Alaska Range passes on Sunday.

&&

.HYDROLOGY...No concerns at this time. We will monitor potential
flash flooding from the day 3-7 hazardous rainfall projections by
WPC .

EXTENDED FORECAST DAYS 4-7...There is good model agreement that a
low will move over the Bering Sea by Sunday...and then up near
the Bering Strait by next Tuesday. The high pressure ridge is
pushed east over the Canadian Yukon and breaks down. A series of
shortwaves will rotate around this low and move up over the
Interior in a moist west-southwest flow. Hazardous rainfall
remains possible on Tuesday over the Brooks Range...and along the
Denali Park Road and north side of the Alaska Range west of the
Parks Highway. Ensemble solutions want to move the Bering low
energy down over the Interior the middle of next week. The cold
frontal boundary forcing will result in widespread rainfall as it
tracks east. Hazardous rainfall will also be possible Wednesday
and Thursday over the eastern Alaska Range and Fortymile country.
This is a wet pattern that will likely settle down our wildfire
activity even more. Even the Yukon Flats could see some widespread
rain late next week.

Coastal Hazard Potential Days 3 and 4...None
