SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
451 PM AKST TUE JAN 31 2012

.SHORT TERM...CURRENT WEATHER IS SOMEWHAT ACTIVE ACROSS THE
PANHANDLE TODAY. A WEAK 992 MB LOW IS PROGRESSING THROUGH THE
SOUTHERN PANHANDLE AT THE MOMENT BRINGING SOME BREEZY CONDITIONS
AND RAIN FROM ICE STRAIT SOUTHWARD. HYDABURG DID REPORT ONE GUSTS
TO 41 KT THIS MORNING AS THE LOW PASSED TO THE NW. THAT LOW IS
EXPECTED TO PASS THROUGH THE PANHANDLE TODAY AND EXIT INTO
BRITISH COLUMBIA THIS EVENING. OTHERWISE, THE REST OF THE
PANHANDLE IS RATHER QUIET WITH ONLY SOME BREEZY CONDITIONS
CURRENTLY OCCURRING FOR SKAGWAY.

 TONIGHT IS RELATIVELY QUIET AS WE ARE IN BETWEEN SYSTEMS. ON AND
OFF LIGHT RAIN, POSSIBLY MIXING WITH SNOW IN THE FAR NORTH, WILL
BE THE RULE OF THE NIGHT. WHERE SNOW IS SEEN ACCUMULATIONS SHOULD
BE LIGHT. WINDS WILL ALSO BE LIGHT AS THE PRESSURE GRADIENT
RELAXES.

 PROBLEMS START SHOWING UP FOR WED AS THE NEXT MAJOR FRONT STARTS
MOVING INTO THE FORECAST AREA. THE PARENT LOW IS CURRENTLY SOUTH
OF THE ALEUTIANS. IT WILL BE GAINING STRENGTH THROUGH THE NEXT
24 HOURS UNDER THE LEFT EXIT REGION OF A 110 KT 500 MB JET,
FINALLY GAINING A CENTRAL PRESSURE OF AROUND 945 MB JUST SOUTH OF
KODIAK ISLAND BY WED AFTERNOON. ASSOCIATED WITH IT IS A STRONG
FRONT THAT WILL BE MOVING EAST ACROSS THE GULF WED. THE OUTSIDE
WATERS WILL BE THE FIRST TO FEEL THE EFFECTS AS STORM FORCE WINDS
PUSH THEIR WAY IN WED MORNING. BY WED AFTERNOON I HAVE STORM
WARNINGS UP FOR THE ENTIRE OUTSIDE WATERS WITH GALE FORCE WINDS
STARTING TO ENCROACH INTO THE INSIDE PASSAGES. WIND GUSTS MAY BE
EVEN HIGHER AS 850 MB WINDS EXCEED 70 KT OVER THE GULF ON WED.
SEAS WILL ALSO BE INCREASING WITH THE LONG SOUTHERLY FETCH AND
STRONG WINDS.

 ON LAND, WINDS WILL ALSO BE STARTING TO INCREASE WED. WINDY
CONDITIONS WITH GUSTS TO 45 MPH WILL BE DEVELOPING ALONG THE
OUTER COAST AND SOUTHERN PANHANDLE WED AFTERNOON WITH BREEZY
CONDITIONS DEVELOPING FARTHER INLAND. WINDS WILL CONTINUE TO
INCREASE INTO WED NIGHT. AS FOR PRECIP, MOST OF IT WILL STILL BE
OFFSHORE BY WED AFTERNOON, BUT THE OUTER COAST MAY START TO SEE
THE LEADING EDGE OF THE PRECIP. WITH TEMPERATURES AS WARM AS THEY
ARE CURRENTLY, THAT PRECIP WILL MOSTLY START OUT AS RAIN. A FEW
AREAS IN THE NORTHERN HALF OF THE AREA MAY SEE SOME SNOW MIX IN
AT FIRST DUE TO EVAPORATIONAL COOLING.

 MODELS ARE DOING SOMEWHAT WELL BUT DIFFERENCES LINGER. GFS WAS
TOO FAR NORTH WITH THE SMALL LOW CURRENTLY GOING THROUGH THE
SOUTHERN PANHANDLE AND WAS TOO WEAK WITH THE NEXT STRONG STORM ON
WED. 0Z EC WAS A BIT BETTER BUT DIDN'T SHOW THE SOUTHERN
PANHANDLE LOW VERY WELL. THAT WAS CORRECTED IN THE NEW 12Z RUN.
NAM AND UK BOTH LOOKED REASONABLE BUT DIFFERED ON WHERE THEY
WANTED TO TAKE THE SOUTHERN PANHANDLE LOW. IN THE END DECIDED TO
GO WITH THE NAM WITH THE 12Z EC MIXED IN IN SOME PLACES. FORECAST
CONFIDENCE IS A LITTLE ABOVE AVERAGE.

&&

.LONG TERM...TWO MAJOR EVENT EXPECTED TO IMPACT SOUTHEAST ALASKA
EARLY ON THE IN THE EXTENDED RANGE FORECAST PERIOD. VERY STRONG
OCCLUDED FRONT WILL LEAD OFF WITH UP TO 60 KT SOUTHEASTERLY WINDS
OVER THE COASTAL MARINE ZONES WEDNESDAY NIGHT. ALSO HAVE 50 KT
STORM FORCE WINDS OVER CLARENCE STRAIT. MUCH OF THE PANHANDLE WILL
SEE STRONG WINDS WEDNESDAY NIGHT AS WELL. STOPPED JUST SHORT OF
HIGH WIND WARNING FOR THE OUTER COAST FROM CAPE SPENCER SOUTH TO
THE DIXON ENTRANCE. A LOW WILL ENTER THE SOUTHEAST GULF THURSDAY
AFTERNOON AND PRODUCE ANOTHER ROUND OF STRONG WINDS AND MAX MARINE
GALES THURSDAY NIGHT. THE OUTER COAST WILL ONCE AGAIN SEE WINDS
GUSTS APPROACHING WARNING LEVELS. SOUTHEASTERLY WINDS WILL BECOME
MORE SOUTHERLY AS THE LOW APPROACHES THE COAST VICINITY CAPE
SUCKLING AND SLOWLY WIND DOWN THROUGH THE DAY FRIDAY.

HEAVY PRECIPITATION ALSO ASSOCIATED WITH BOTH OF THESE SYSTEMS. SOME
LOCATIONS EXPECTED TO SEE IN EXCESS OF 4 INCHES OF RAIN THROUGH
THE SECOND HALF OF THIS WEEK AND THOSE LOCATIONS WITH A
SIGNIFICANT SNOW PACK STILL ON THE GROUND...AND ON STRUCTURE
ROOFS...WILL NEED TO TAKE CARE TO PREVENT POSSIBLE STRUCTURAL
FAILURE UNDER VERY HEAVY SNOW LOADING. URBANIZED AREAS WITH
CLOGGED STREET DRAINS MAY ALSO EXPERIENCE SIGNIFICANT PONDING OF
WATER ON ROADWAYS.

MOST OF THIS 2-PART PRECIPITATION EVENT WILL BE IN THE FORM OF
RAIN. THE PROBLEM...AND CONCERN...WILL BE THE HAINES AND SKAGWAY
ZONES. BASED ON CURRENT FORECAST TEMPERATURES AND RESULTING SNOW
LEVELS, A HEAVY SNOW EVENT IS FORECAST FOR THESE TWO ZONES. IN
SKAGWAY, THE MAIN THREAT WILL BE AT HIGHER ELEVATIONS ALONG THE
KLONDIKE HIGHWAY. FOR HAINES, HOWEVER, FORECAST SNOW LEVELS ARE
LOW ENOUGH TO GENERATE SIGNIFICANT SNOW FROM IN TOWN TO THE BORDER
ALONG THE HIGHWAY. HAVE ISSUED A WINTER STORM WATCH FOR HEAVY
SNOW WITH THE AFTERNOON FORECAST AS A RESULT. CONFIDENCE NOT
SUFFICIENT TO ISSUE A THIRD PERIOD WARNING, AS THE DIFFERENCE
BETWEEN HEAVY RAIN AND HEAVY SNOW IS ONLY A FEW DEGREES. WITH
ENOUGH OF A SOUTHERLY WIND, SNOW LEVELS MAY RISE ENOUGH SUCH THAT
SIGNIFICANT SNOWFALL WILL BE LIMITED TO WESTERN PORTIONS OF THE
HIGHWAY.

MODEL AGREEMENT FAIR AT BEST DUE TO STRENGTH AND TRACK OF THE
SYSTEMS INVOLVED. USED A BLEND OF GFS, UKMET, GEM, AND ECMWF
EARLY ON. MOVED TO A BLEND OF ECMWF AND GFS IN THE MID RANGE AND
THEN STRAIGHT HPC FOR THE LATTER HALF OF THE FORECAST. CONFIDENCE
IS ABOVE AVERAGE FOR A SIGNIFICANT WIND AND PRECIP EVENT, BUT ONLY
AVERAGE TO BELOW AVERAGE ON THE DETAILS.

.AJK WATCHES/WARNINGS/ADVISORIES...
PUBLIC...STRONG WIND FROM WEDNESDAY AFTERNOON THROUGH LATE WEDNESDAY
     NIGHT FOR AKZ022-026.
