NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
500 AM AKDT TUE MAY 31 2011

.DISCUSSION...
MODELS IN DECENT AGREEMENT THROUGH ABOUT 60 HOURS. LARGE LOW
MOVING NORTH IN THE BERING SEA WILL SPREAD RAIN ALONG THE WEST
COAST BEGINNING LATE THIS AFTERNOON AND EVENING. THE GRADIENT WILL
INCREASE SIGNIFICANTLY OVER PORTIONS OF THE WEST COAST AS THE LOW
MOVES NORTH AND CONTRASTS THE HIGH PRESSURE NORTH OF THE ARCTIC COAST.

THERMAL TROUGH THROUGH THE MIDDLE OF THE STATE WILL CONTINUE THE
THREAT OF THUNDERSTORMS THROUGH AT LEAST WED THROUGH THE CENTRAL
PORTION OF THE STATE. FAIRBANKS MORNING RAOB INDICATES SUFFICIENT
MOISTURE WITH A CONTINUED RESPECTABLE CAPE VALUE OF AROUND 640
JOULES AND A LI OF -2.6. THIS IS SLIGHTLY MORE STABLE THAN 24
HOURS AGO BUT STILL WELL WITHIN THE FRAME OF CONVECTION
POSSIBILITIES. THERE IS A COUPLE OF AREAS WHERE THERE IS A SLIGHT
CAP BUT AIR PARCEL SHOULD BE ABLE TO OVERRIDE THE CAP BY AFTERNOON.

SIGNIFICANTLY COLDER AIR ALOFT WILL ATTEMPT TO SLIDE SOUTHWARD
OVER THE ARCTIC COAST BUT APPEARS THAT IT WILL IMPACT THE WESTERN
CANADIAN ARCTIC COAST INSTEAD OF THE ALASKA ARCTIC COAST. BUT WHAT
THIS DOES APPEAR TO DO IS SEND ENOUGH COLDER AIR DOWN ALONG THE
EASTERN PORTION OF THE STATE TO ENTRAIN INTO THE AIR MASS TO COOL
IT OFF AT LOWER LEVELS. THIS SHOULD TRANSLATE INTO SOMEWHAT
COOLER TEMPERATURES OVER MOST OF NORTHERN ALASKA BY THU AND TEN
CONTINUE INTO NEXT WEEK.

WINDS IN MARINE ZONE 210 SHOULD REMAIN AT OR ABOVE ADVISORY LEVEL
THROUGH MUCH OF THE WEEKEND WITH GENERAL LOW PRESSURE JUST SOUTH
OF ZONE 210 AND HIGH PRESSURE NORTH OF THE ARCTIC COAST.

&&

.FIRE WEATHER...SEVERAL FIRES BURNING AROUND THE STATE. THESE
SHOULD RECEIVE LITTLE TO NO HELP TODAY AND WED AS THE STRONG RIDGE
OVER THE CENTRAL INTERIOR CONTINUES WITH LOWER RH VALUES IN
DAYTIME SURFACE HEATING BUT SHOULD RECOVER DURING THE NIGHT TIME
HOURS.

&&

.HYDROLOGY...FLOOD ADVISORY FOR THE COLLVILLE RIVER NEAR COLLVILLE
VILLAGE REMAINS IN EFFECT THROUGH LATE WED AFTERNOON.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...
FIRE WEATHER WATCH FOR AKZ223-AKZ225-AKZ226.

SMALL CRAFT ADVISORY FOR PKZ200-PKZ230.
