.SYNOPSIS...
A bit of active weather is coming our way this week and it begins
this evening with southerly gap winds through Windy Pass which may
be upwards of 55 mph. There will also be a front moving over the
Alaska Range which provides light snow and rain to the Interior
tonight through Tuesday AM. Brief, transient ridging moves in from
the West Tuesday morning and across the state by Wednesday
morning, then a larger low pressure moves into the Alaska
Peninsula Wednesday night bringing widespread snow, rain and gusty
winds to Western Alaska.

.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- Isabel Pass winds gusting to 55 mph tonight into tomorrow AM.

- Light rain and snow moves from east to west tonight and stalls
  with rain/snow showers from Bettles to Minchumina Monday eve.
- Light snow moves back east Monday night into Tuesday with snow
   accumulations around 1 inch or less in the Fairbanks bowl, 1-2
   inches possible in the hills north/east, though daytime heating
   will limit accumulations.

- Temperatures remain seasonably warm with highs in the 40s and
  lows in the teens/20s across the Interior.

- Stronger gap winds return Wednesday and especially Wednesday
  night with gusts upwards of 70 mph possible.

West Coast and Western Interior...
- Gusty winds along the coast will be weakening through the
  afternoon today.

- Relatively quiet weather persists tomorrow besides a few rain
  and snow showers from McGrath to Galena northward.

- Tuesday dries out, then a low in the Pacific aims at the Alaska
  Peninsula Wednesday into Thursday.
- This low will bring gusty winds and widespread rain/snow.
- Valley locations in SW Alaska may begin as snow Wednesday
   morning before changing over to rain. For the rest of the West
   Coast and West Interior, elevations over 2000 feet look to
   remain mostly snow with some mixing possible, while valleys
   remain mostly rain.

North Slope and Brooks Range..
- Stratus, fog and flurries remain along the Arctic Coast with
  northwest flow continuing through the week. Winds will remain
  around 10 to 20 mph through tomorrow, then weaken.
- Barter Island will be the windiest today with gusts to 45 mph,
   then weakening tomorrow afternoon.

- Light snow in the Brooks Range Monday afternoon/evening but
  accumulations will be around an inch or less.

- Light snow along the Eastern Arctic Coast Monday afternoon
  through Tuesday afternoon with 0.5 to 1.5 inches of
  accumulation.

- Another round of snow moves in Wednesday night, especially in
  the southern slopes of the Western Brooks Range.

.FORECAST ANALYSIS AND DISCUSSION...
Not much change in the analysis from yesterday. A 505 decameter
low in the NW Gulf of Alaska is moving northeast and weakening. A
front from this low will move over the Alaska Range and into the
Interior on Monday bringing chances for snow and rain. From here,
the CMC, NAM and ECMWF all take the low to Yakutat and into the
southern Yukon by Tuesday. The GFS still moves it towards Juneau
and cuts it southeast which remains the outlier solution and
won`t be given much weight. Nonetheless, the front in the Interior
associated with this low will be pretty uneventful. An initial
round of snow and rain is likely on Monday with snow/rain showers
likely in the valleys and snow in the higher terrain. The front
will pivot west of Fairbanks Monday eve and move back over the
Central Interior with a second round of light snow/snow showers
Monday night into Tuesday. So is likely in the Central/Eastern
Brooks Range as well. Overall, snow totals will be light,
especially with any snow during the daylight hours since the sun
will be melting it on the ground. Most precipitation ends by
Tuesday night with Wednesday being dry. A low in the Northern
Pacific will be moving towards SW Alaska by then and this will
bring very messy weather in Western Alaska as well as strong
Alaska Range gap winds Wednesday afternoon into Thursday.

&&

.EXTENDED FORECAST DAYS 4-7...
A low in the Northern Pacific will move into the Alaska Peninsula
and bring gusty winds to Western Alaska as well as widespread
snow and rain, with the highest probability for rain being in the
Western Alaska valleys/lower elevation. A ridge will be over SE AK
and the Yukon Territory. In between the ridge and low will be a
tight southerly pressure gradient, resulting in strong, near
warning level wind gusts through the Alaska Range. From here,
confidence is increasing for where the low goes. As we expected
yesterday, the low should move northward into the Western
Interior. This could bring widespread rain and snow to the Brooks
Range and Interior by Thursday/Friday, but it will be weakening
rapidly with southerly flow over the Alaska Range, so much of the
Interior may remain dry. The southern slopes of the Brooks Range
however, will be upsloped, so precipitation looks more likely
there. Otherwise, the weather looks to quiet out next weekend as a
high builds in.

Coastal Hazard Potential Days 3 and 4...None
