Brisk Wind Advisory 16, NWS Fairbanks, AK

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
142 PM AST SUN JAN 22 2006

.DISCUSSION...
SLIGHT DIFFERENCES EXIST IN THE MODELS. AT THIS TIME PREFER THE
GFS. THE GFS INITIALIZED PRETTY WELL. THE ETA IS BUILDING THE
RIDGE IN THE BERING VERY STRONG. BELIEVE THAT AS THE RIDGE BUILDS
EAST ACROSS NORTHERN ALASKA IT WILL STRENGTHEN WITH THE COLD AIR
IN PLACE.

THE UPPER LEVEL TROUGH CONTINUES TO WORK ITSELF EASTWARD AND AS IT
DOES SO WILL PUSH A MAJORITY OF THE COLD AIR INTO FAR WESTERN
CANADA. THE RIDGE BOTH AT THE SURFACE AND ALOFT BUILDING IN THE
NORTHERN PACIFIC WILL STRETCH ACROSS NORTHERN ALASKA AND BEGIN TO
PUSH SOME MUCH WARMER AIR INTO THAT REGION. HOWEVER THE STRONG
ARCTIC LOW WILL PUSH ANOTHER SHOT OF COLDER AIR DOWN THE EASTERN
PORTION OF THE STATE WHICH WILL EXTEND THE LONGEVITY OF THE UPPER
LEVEL TROUGH.

THE UPPER LEVEL RIDGE IN THE NORTH PACIFIC WILL BE EVENTUALLY
SQUASHED UNDER BY THE STRONG LOW PRESENTLY NEAR THE KAMCHATKA
PENINSULA. THIS WILL ENABLE THE UPPER LEVEL TROUGH THAT WILL BE
SITTING NEAR THE ALCAN BORDER TO SPREAD COLDER AIR BACK WEST IN
THE NORTHERN AND CENTRAL PART OF THE STATE.

THE SNOW OVER THE EASTERN INTERIOR IS COMING TO AN END. AS THE
ARCTIC BOUNDARY PUSHES WEST AND THE WINDS BEGIN TO USHER IN DRIER
AIR FROM THE NORTH AND WEST THE OVERRUNNING SITUATION WILL END.
THE SKIES WILL BEGIN CLEARING OVER THE CENTRAL AND NORTHERN
INTERIOR THIS AFTERNOON AND ALLOWING THE TEMPERATURES TO DROP
SIGNIFICANTLY AGAIN TONIGHT IN THE CLEAR AREAS.
