thunderstorms through the weekend while the North Slope gradually

  Alaska Range which will be isolated throughout the Interior.

  to some wet weather, especially in the Eastern Interior.
- Rain, heavy at times on Saturday and Sunday in the Fortymile
   with the potential for it to continue through Monday.
- Potentially an inch or more of rain can fall from here to the
   Eastern Alaska Range as moist, northeast, upslope flow
   persists.

-Expect seasonable temps through the weekend.

West Coast and Western Interior...
- Moderate to heavy rain today into tomorrow morning for the
  Western Interior from the Lower Yukon Valley to the Brooks Range
  with a widespread 0.25 to 0.50" and locally up to an inch with

.FORECAST ANALYSIS AND DISCUSSION...
A strong shortwave which provided nearly an inch of rain to the
Fairbanks area yesterday into today is moving off to the Western
Interior. This will stall a bit today and tomorrow before drifting
south. It will bring a heavy amount of rain to the Western
Interior. Easterly flow continues in the Eastern Interior with
chances for showers and storms, especially in the Northern
Interior and Southern Brooks Range. A ridge aloft tries to build
in from the east on Sunday with a low in the Gulf of Alaska. This
will set up northeast flow in the Eastern Interior, susceptible
for heavy rain and upslope flow from the Fortymile to the Eastern
Alaska Range. Otherwise, the weather remains mostly quiet on the
North Slope.

&&

.FIRE WEATHER...
Thunderstorms will persist through the weekend with activity
becoming more spotty. The bulk of the activity today will be in
the Northern Interior and Brooks Range. Tomorrow it spreads south
to the Eastern Interior and Brooks Range with the focus on
Saturday and Sunday being in the Southeast Interior from the
Fortymile to the Eastern Alaska Range. Heavy rain is likely in the
Western Interior today with the Central and Eastern Interior
drying out today and tomorrow. Heavy rain is then looking more
likely in the Fortymile and Eastern Alaska Range Sunday through
early next week with the potential for an inch or more of rain.
Temperatures will be seasonably warm, mostly in the mid/upper 60s
to the mid 70s with the warmest spot being in the Yukon Flats.

&&

.HYDROLOGY...
No concerns with the rivers, they will be gradually dropping.

&&

.EXTENDED FORECAST DAYS 4-7...
There are couple of things we are watching in the extended range.
First is Sunday to Tuesday, northeasterly flow in the Southeast
Interior and Eastern Alaska Range which can bring the potential
for heavy rain. The second is the potential for a blocking
pattern. There has been hints of a rex block (high over low
pressure) or an omega block (low, high, low from west to east).
There is some uncertainty with the overall pattern evolution but a
high is looking more likely to build into Alaska with a low in, or
near the Gulf of Alaska. This could bring the potential for
another week of high thunderstorm activity and warmer
temperatures.

Coastal Hazard Potential Days 3 and 4...None
