High Wind in Alaska, September 12 to 13, 2014

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
321 PM AKDT FRI SEP 12 2014

.DISCUSSION...
MODELS IN DECENT AGREEMENT THROUGH 48 HOURS. BERING SEA LOW HAS
BEEN REPLACED BY OLD TROPICAL TYPHOON. THIS WILL BRING A DECENT
AMOUNT OF PRECIPITATION TO THE WEST COAST ZONES IN A SHORT PERIOD
OF TIME. THE FRONT IS RELATIVELY FAST MOVING SO THE POTENTIAL FOR
INUNDATING RAIN IS NOT VERY HIGH.

UPPER LEVEL RIDGE OVER THE EASTERN PORTION OF THE STATE WILL
CONTINUE TO EDGE EASTWARD THROUGH THE WEEKEND. SURFACE GRADIENT
WILL REMAIN TIGHT OVER THE ALASKA RANGE THROUGH TONIGHT BUT THE
UPPER LEVEL GRADIENT WILL CONTINUE TO TIGHTEN OVER THE ALASKA
RANGE THROUGH SAT.

THE GRADIENT OVER THE ARCTIC COAST IS INCREASING AS THE LOW IN THE
BERING SEA IS DEEPENING. THE WINDS WILL CONTINUE TO BE AT MARINE
ADVISORY LEVEL THROUGH AT LEAST THE FIRST PART OF THE WEEK. EXPECT
STRATUS AND FOG WITH EITHER ONSHORE OR PARALLEL FLOW. THE FRONT
FROM THE NEW LOW IN THE BERING SEA WILL MOVE OVER THE ARCTIC COAST
SUN AND SPREAD A FEW SHOWERS.

WEST COAST...RAIN TONIGHT AND SAT WHILE THE STRONG FRONTAL
BOUNDARY RAPIDLY PUSHES NORTHWARD THROUGH THE DAY ON SAT. THE
FRONT SHOULD PASS THE SEWARD PENINSULA BY LATE SAT MORNING AND
THEN CONTINUE NORTHWARD.

INTERIOR...STRONG SOUTHERLY WINDS THROUGH THE ALASKA RANGE
THROUGH SAT BUT EXTENDING INTO SUN FOR THE EASTERN ALASKA RANGE.
PRECIPITATION WILL BE CONFINED TO WEST OF THE ALASKA RANGE.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
