SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
112 PM AKST TUE FEB 28 2012
.SHORT TERM...SATELLITE IMAGERY THIS AFTERNOON SHOWING A BROAD
AREA OF LOW PRESSURE WITH TROUGH AXIS OVER THE EASTERN AK GULF
AND SHOWERS MOVING NORTHWARD OVER THE AK PANHANDLE. THIS AREA OF
LOW PRESSURE WILL WEAKEN ALONG THE COAST WITH A LOW CENTER
REDEVELOPING SOUTH OF HAIDA GWAII. SHOWERS HAVE BECOME SCATTERED
THEN WILL BECOME ISOLATED AS UPPER LEVEL DYNAMICS WEAKEN SHOWER
ACTIVITY HAS BEEN MAINLY SNOW OVER THE NORTHERN PANHANDLE WITH A
MIX OF RAIN AND SNOW FREDERICK SOUND SOUTH. ADDITIONAL SNOW
ACCUMULATION SHOULD BE LESS THAN 1 INCH. WHILE THERE WILL BE
CLEAR BREAKS THROUGH THE SHORT TERM SKIES WILL BE MOSTLY CLOUDY
AS SOUTHEASTERLY WINDS AT MID LEVELS KEEP CLOUD MASS MOVING OVER
THE PANHANDLE. WINDS HAVE BEEN LIGHT EASTERLY BUT WILL SEE SOME
INCREASE IN GAP FLOW AS HIGH PRESSURE DEVELOPS OVER NORTHERN
BRITISH COLUMBIA TIGHTENING THE EAST-WEST PRESSURE GRADIENT.
NORTHERN INNER CHANNEL WINDS WILL INCREASE TO SMALL CRAFT LEVELS
AS NORTH-SOUTH GRADIENT INCREASES WITH LOW TO THE SOUTH OF HAIDA
GWAII AND HIGH PRESSURE OVER THE YUKON. LOWERS OVERNIGHT
TEMPERATURES A BIT WITH FLOW FROM CANADIAN INTERIOR BUT COULD SEE
TEMPS EVEN LOWER IF THERE IS INCREASED CLEARING AND RADIATIONAL
COOLING.
MODELS WERE IN GOOD AGREEMENT THIS MORNING WITH THE 12Z NAM
INITIALIZING WELL. BIGGEST DIFFERENCE WAS THE GFS INDICATING A
STRONGER NORTH-SOUTH GRADIENT WEDNESDAY COMPARED TO THE NAM AND
ECMWF. GFS ALSO KEPT SHOWER ACTIVITY MORE OFF SHORE LATE TONIGHT
INTO WEDNESDAY. USED A BLEND OF 12Z NAM WITH INHERITED GRIDS BUT
OVERALL CHANGES WERE MINOR. FORECAST CONFIDENCE IS ABOVE AVERAGE
WITH MAIN QUESTION CONCERNING OVERNIGHT TEMPERATURES.
&&
.LONG TERM...MODELS ARE IN DECENT AGREEMENT THROUGH THE FIRST
HALF OF THE EXTENDED PERIOD. THE ONLY REAL DIFFERENCES NOTED
BEFORE SUN HAVE TO DO WITH A FRONT THAT AFFECTS THE AREA THURS
NIGHT. TIMING IS NOT TOO BAD BETWEEN THE MODELS. WHAT PRECIP WILL
FALL IS A BIT MORE DIFFICULT AS THE NAM IS GOING THE COLD ROUTE
WHILE THE GFS AND EC ARE A BIT WARMER BASED ON FORECAST 1000 TO
850 MB THICKNESS VALUES. ALSO ONCE THE FRONT MOVES THROUGH SW
WINDS BEHIND IT ARE SPLIT BETWEEN THE EUROPEAN AND NCEP MODELS.
THE EUROPEAN MODELS ARE GOING FOR SMALL CRAFT SW WINDS WHILE THE
NCEP MODELS ARE GOING FOR GALES DUE TO A TIGHTER PRESSURE
GRADIENT S OF A STRONGER LOW. ENDED UP GOING WITH THE GFS FOR ANY
UPDATES IN THE MID RANGE DUE TO BETTER RUN TO RUN CONSISTENCY AND
MY THINKING THAT THE NAM WAS A BIT TOO COLD DURING FRONTAL
PASSAGE THURS NIGHT.
CONCERNING THE FRONT, IT APPEARS THAT THE FRONT WILL BE RATHER
FAST MOVING AND WILL BE OF WEAK TO MODERATE STRENGTH DUE TO ITS
DISTANCE FROM ITS PARENT LOW. IT ALSO HAS TO OVERCOME A RIDGE
ALOFT TO GET HERE. WINDS WILL MAINLY BE CONFINED TO THE GULF AND
OUTER COAST WITH GALES BRIEFLY EXPECTED IN THE GULF BEFORE THE
FRONT COMES ASHORE. AS FOR PRECIP, MOST PLACES, EXCEPT FOR THE
FAR SOUTH AND OUTER COAST WILL START OUT AS SNOW OR A MIX OF RAIN
AND SNOW THURS AFTERNOON. YAKUTAT WILL START CHANGING OVER TO
LIQUID THURS NIGHT AND THE REST OF THE PANHANDLE MAY WAIT UNTIL
FRI MORNING TO CHANGE. THE SNOW AMOUNTS I HAVE REACH MINIMUM
ADVISORY FOR THE NORTHERN HALF OF THE AREA THURS NIGHT AT THE
MOMENT.
MODEL AGREEMENT STARTS TO REALLY FALL APART FOR SUNDAY AND
BEYOND AS THE GFS DUG A DEEPER 500 MB TROUGH OVER THE EASTERN
GULF THEN THE 0Z EC WAS SHOWING ON SUN. THE 12Z EC HAS SINCE
FOLLOWED SUIT BUT THERE ARE STILL SOME LARGE DIFFERENCES ONCE YOU
GET INTO NEXT WEEK. DECIDED TO STICK WITH HPC DATA FOR SUNDAY AND
BEYOND FOR ITS USE OF ENSEMBLE DATA. FORECAST CONFIDENCE IS ABOUT
AVERAGE.
