NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
237 AM AKDT MON APR 18 2016

.DISCUSSION...

MODELS...GOOD AGREEMENT THROUGH 36 HOURS...AND MUCH BETTER
AGREEMENT INTO THE MID TERM COMPARED TO THE LAST FEW RUNS. ALL
THERMAL TROUGH AND LOW NOT AS PREVALENT IN THE MODELS IN THE
UPPER TANANA VALLEY THIS AFTERNOON AND EVENING AS UPPER LEVEL LOW
MOVES OVER THE AREA. THE GFS CONTINUES TO PRODUCE TOO MUCH
PRECIPITATION ACROSS THE INTERIOR SO WILL RELY ON THE NAM AND
ECMWF. WILL ONLY MAKE MINOR CHANGES TO THE FORECAST DATABASE. VERY
ISOLATED CONVECTIVE LOW TOP SHOWERS IN THE INTERIOR...MAINLY EAST
OF FAIRBANKS DURING THE AFTERNOON AND EVENING AS ALL THE MODELS
HAVE SOME NEGATIVE LIFTED INDICES AGAIN TODAY.

ALOFT...AT 500 HPA...RIDGING OVER THE EASTERN INTERIOR IS PUSHED
BACK OVER THE YUKON TERRITORY TODAY AS THE 532 DAM LOW SOUTH OF
YAKUTAT MOVES OVER THE UPPER TANANA VALLEY THIS AFTERNOON BRINGING
SOME GOOD MOISTURE THEN MOVES EAST IN THE EVENING. TROUGH REMAINS
OVER THE ARCTIC WITH A 530 DAM CENTER OVER BARROW AND A 529 DAM
CENTER OVER POINT HOPE. A WEAK 537 DAM HIGH SITS OVER THE
SOUTHWEST MAINLAND. THE TROUGH OVER THE NORTHWEST COAST WILL
SLOWLY MOVE TO THE WEST AS THE RIDGE BUILD BACK IN OVER THE
SOUTHEASTERN INTERIOR AND OVER THE WHOLE FORECAST AREA BY TUESDAY
AFTERNOON. A 549 DAM HIGH NEAR 81N 170W REMAINS STATIONARY THROUGH
WEDNESDAY MORNING THEN MOVES SOUTHEAST TO 75N 155W BY LATE
WEDNESDAY. A BROAD AREA OF LOW HEIGHTS WILL PERSIST OVER THE
CENTRAL ALEUTIANS THROUGH WEDNESDAY. AT 850 HPA...THE TEMPERATURES
ARE RELATIVELY STEADY THROUGH THURSDAY THEN WARMING TO AROUND ZERO
CELSIUS SOUTH OF THE YUKON RIVER.

SURFACE...RIDGING WILL PERSIST OVER THE ARCTIC. BROAD CYCLONIC
PATTERN CONTINUES OVER MAINLAND ALASKA WITH LEESIDE TROUGHING AND
THERMAL TROUGH AND LOW NORTH OF THE ALASKA RANGE IN THE UPPER
TANANA VALLEY. THE THERMAL TROUGH AND LOW WILL NOT BE AS STRONG
TODAY AS THE LAST COUPLE DAYS SO CONVECTION WILL BE VERY LIMITED
IF ANY OCCURS. PRESSURE GRADIENT OVER THE ARCTIC COAST IS
TIGHTENING UP A BIT AS THE HIGH DRIFTS SOUTH A BIT. THE LOW OVER
THE NORTH PACIFIC HAS INCREASED THE GRADIENT AROUND ST LAWRENCE
ISLAND AS A DECAYING FRONTAL BAND LIES IN THE AREA. A 1011 MB LOW
THAT MOVED FROM THE GULF TO THE UPPER TANANA VALLEY WILL BE
ABSORBED BY A 1000 MB LOW OVER NORTHERN BRITISH COLUMBIA THIS
MORNING.

ARCTIC COAST AND BROOKS RANGE...STATUS QUO. THE ONLY CHANGE WILL
BE THE WINDS PICKING UP A BIT THROUGH THE DAY AND THIS IN TURN
WILL PUSH VISIBILITIES DOWN IN BLOWING SNOW. STRATUS CONTINUES TO
FLOW OVER THE AREA FROM THE CANADIAN ARCHIPELAGO. THE BLOWING SNOW
COMBINING WITH FOG AND FLURRIES WILL REDUCE VISIBILITY EVEN MORE.
HOW POOR THE VISIBILITY IS IN ANY LOCATION WILL DEPEND ON HOW
MUCH SNOW THERE IS LEFT TO BLOW AROUND AND HOW MUCH FOG THERE IS.
WINDS NORTHEAST TO EAST AT 15 TO 35 MPH ALONG THE COAST. THE
STRONGEST WINDS WILL BE SOUTHWEST OF WAINWRIGHT AND NORTH OF CAPE
LISBURNE.

WEST COAST AND WESTERN INTERIOR...MOSTLY CLOUDY ALONG THE COAST
WITH MOSTLY SUNNY CONDITION IN THE INTERIOR. NOT A LOT OF
PRECIPITATION EXPECTED IN THE FORECAST AREA. THE EXCEPTION WILL
BE LAWRENCE ISLAND AS THE DECAYING FRONT LIES IN THE VICINITY SO
THEY COULD GET A COUPLE INCHES OF WET SNOW. WINDS OF 30 TO 40 MPH
AND BLOWING SNOW ARE BECOMING AN ISSUE AROUND GAMBELL ON ST
LAWRENCE ISLAND SO WILL ISSUE A WINTER WEATHER ADVISORY. WINDS
OVER THE REMAINDER OF THE AREA WILL GENERALLY BE NORTHEAST AT 5 TO
15 MPH...EXCEPT ON THE BERING STRAIT COAST WHERE WINDS WILL BE IN
THE 15 TO 30 MPH RANGE. CONDITIONS ON ST LAWRENCE ISLAND IMPROVING
IN THE AFTERNOON TUESDAY AS THE WINDS DIMINISH.

CENTRAL AND EASTERN INTERIOR...ONE LIGHTNING STRIKE YESTERDAY
SOUTH OF FAIRBANKS. TODAY LOOKS TO BE MORE STABLE IN THE
MODELS...BUT THERE IS STILL POTENTIAL FOR SOME LOW TOP CONVECTIVE
SHOWERS IN THE UPPER TANANA VALLEY. A BIT CLOUDIER TODAY ACROSS
THE AREA WITH SLIGHTLY LOWER TEMPERATURES. WINDS WILL CONTINUE TO
BE RELATIVELY LIGHT ACROSS THE AREA WITH SOME GUSTY WINDS AROUND
THE THERMAL TROUGH AND LOW IN THE UPPER TANANA VALLEY.

&&

.FIRE WEATHER...A SINGLE LIGHTNING STRIKE SOUTH OF FAIRBANKS
YESTERDAY. THERE CONTINUES TO BE SOME CONVECTIVE POTENTIAL...BUT
LESS THAN YESTERDAY AND WITH CLOUDIER AND COOLER CONDITIONS DO NOT
EXPECT ANY...BUT WOULD NOT BE SURPRISED BY A FEW STRIKES NEAR THE
BORDER. MORE GUSTY WINDS AROUND THE THERMAL TROUGH YESTERDAY AND
THAT WILL NOT CHANGE SO SO EXPECT A FEW GUSTS TO AROUND 25 MPH
DURING THE AFTERNOON AND EARLY EVENING.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...

WINTER WEATHER ADVISORY FOR AKZ213.

HEAVY FREEZING SPRAY WARNING FOR PKZ210.

GALE WARNING FOR PKZ210.

BRISK WIND ADVISORY FOR PKZ225-PKZ230.
