Brisk Wind Advisory 33, NWS Fairbanks, AK

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
135 PM AST FRI FEB 2 2007

.DISCUSSION...
THE 3RD IN A SERIES OF LOWS FROM THE NORTH PACIFIC TO HEAD INTO
THE BERING SEA IS NOW IN THE CENTRAL BERING AND HEADED TO THE GULF
OF ANADYR. THE COLD AIR COMING IN ON THE SOUTH QUADRANT OF THE LOW
WILL HELP MAINTAIN THE STRENGTH OF THE WIND ON THE BERING SEA AND
ARCTIC COASTS THIS EVENING AND TONIGHT. A GRADUAL DECREASE IN
COASTAL WINDS IS EXPECTED SATURDAY.

THE OCCLUDED FRONT WITH TODAYS BERING SEA LOW HAS ADVANCED OVER
NORTHERN ALASKA WITH VERY LITTLE PRECIPITATION. THERE WAS A
NARROW BAND ON THE RADAR AT NOME THIS MORNING AND SURFACE REPORTS
OF PRECIPITATION HAVE BEEN FEW AND BRIEF.

THE 4TH LOW IN THIS SERIES IS DUE TO REACH THE CENTRAL ALEUTIANS
SATURDAY AFTERNOON. THIS SYSTEM IS NOT EXPECTED TO ADVANCE
NORTHWARD AS ITS PREDECESSORS HAVE...SO THERE WILL BE RELATIVELY
LITTLE IMPACT ON THE WEST COAST WINDS AND VERY LITTLE IF ANY
INFLUX OF PRECIPITATION FROM THE ALEUTIAN LOW THIS WEEKEND. FROM
SUNDAY ONWARD...CIRCULATION OVER NORTHERN ALASKA OUT TO ABOUT 160
DEGREES WEST WILL BECOME LIGHT EASTERLY AND BRING IN COOLER AIR.
THE FLOW OVER THE WEST COAST WILL BE SOUTHERLY...SO CLOUD COVER
CAN BE EXPECTED TO REMAIN THERE.

HYDROLOGY...THE UNUSUALLY WARM WEATHER OF THE PAST WEEK HAS
PARTIALLY OPENED SOME AREA RIVERS...THOSE STRETCHES THAT FLOW
FAST. THIS HAS RESULTED IN SOME OVERFLOW ON THE NENANA RIVER NEAR
ANDERSON DURING THE PAST SEVERAL DAYS. WITH THE COOLER
TEMPERATURES TO COME STARTING SUNDAY THIS PROBLEM SHOULD SUBSIDE.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...SOUTHEAST GALES SAINT
LAWRENCE ISLAND SUNDAY AND SUNDAY NIGHT.
