Northern Alaska Forecast Discussion

.DISCUSSION...
An active southerly flow pattern continues across northern
Alaska. Overall, the models are in good agreement though Thursday
in terms of the overall synoptic scale pattern.

Central and Eastern Interior: The biggest issue in the short term
will be the winds in the Alaska Range. High Wind Warnings are out
for the Alaska Range with a Wind Advisory for the Delta Junction
area. We expect winds to continue to increase this afternoon and
peak this evening. There will be a brief break in the winds
overnight; however, current thinking is that winds will increase
again tomorrow with the strongest winds expected in the evening.
Little to no precipitation is expected out through Thursday. For
areas from Fairbanks south any precipitation that does fall
during this time will likely be freezing rain or rain due to warm
temperatures aloft; however, because of the downsloping winds off
of the Alaska Range precipitation making it to the ground is
fairly unlikely.. Warm surface temperatures are expected to
continue tomorrow with a cooling trend beginning on Thursday.

North Slope and Brooks Range: Winter Weather Advisories are out
all along the coast mainly for blowing snow. Current expectation
is that winds will increase all along the coast tonight and
especially tomorrow causing the visibility to decrease. Winds
decrease a bit Thursday; however, a band of snow is expected to go
through around the same time that the winds begin to decrease.
This snow band will bring an inch or two of snow as it moves
across.

West coast and Western Interior: A northward moving weather
system will bing precipitation to portions of the west coast and
western Interior tonight into tomorrow. Warmer temperatures aloft
will result in a mixed bag of precipitation types. Winter weather
advisories remain in effect for zones 211, 212 and 214. Winter
storm warnings for freezing rain are out for zones 215 and 216
where higher QPF values are expected during the period where the
sounding supports freezing rain. Snow is expected north of the
Seward Peninsula Wednesday night into Thursday morning as a
weather front move to the north. Up to 4 inches of snow is
possible in zones 207, 208 and 217.

Coastal Hazard Potential Days 3 and 4...None.
