SOUTHEAST ALASKA FORECAST DISCUSSION
1100 AM AST SUN FEB 10 2008

.SHORT RANGE...COMPLEX LOW CONTINUES TO SLIDE EASTWARD THIS
MORNING.  SATELLITE IMAGERY DEPICTS TWO CENTERS OF CIRCULATION.
THE FIRST IS RAPIDLY MOVING EAST ACROSS HECATE STRAIT AND THE
SECOND IS JUST SOUTH OF ICY BAY DRIFTING NORTHEASTWARD.
MEANWHILE A RAPIDLY EVOLVING LOW WILL A DOUBLE CIRCULATION IS
HEADED NORTHEASTWARD INTO THE SOUTHWEST GULF THIS MORNING.
TEMPERATURES CONTINUE TO SLOWLY WARM FROM THE SOUTH.  THE SITKA
AREA AND POINTS SOUTH OF SUMNER STRAIT ARE NEAR OR ABOVE FREEZING
WHILE THE CENTRAL INNER CHANNELS ARE WARMING INTO THE LOWER 20S.
COLDER AIR REMAINS ENTRENCHED IN THE FAR NORTHERN INNER CHANNELS
AS WELL A THE PORTLAND CANAL AREA WHERE COLDER INTERIOR AIR
DRAINAGE REMAINS.

EXPECT PRECIPITATION TO TAPER OFF SLIGHTLY THIS
AFTERNOON...PARTICULARLY IN THE SOUTH AS THE AFOREMENTIONED
HECATE STRAIT LOW MOVES INLAND.  THE NORTHERN GULF LOW IS
EXPECTED TO SHIFT EAST AND WILL CONTINUE TO CIRCULATE ONSHORE
MARINE AIR OVER THE NORTHERN HALF.  HEAVY SNOW WARNINGS ARE ON
TRACK TO EXPIRE THIS EVENING ACROSS THE NORTHERN CHANNELS WITH
WARMER AIR INFILTRATING THE AREA AND LESS FAVORABLE PRECIPITATION
AMOUNTS.  THE EXCEPTION WILL BE ZONES 18...19 AND 29 WITH COLD
DRAINAGE AIR CREATING MORE ENHANCEMENT OF THE EXPECTED
PRECIPITATION.  FURTHERMORE...THE SOUTHWESTERN GULF LOW IS
EXPECTED TO MOVE AN OCCLUSION NORTHEASTWARD ACROSS THE PANHANDLE
TONIGHT AND WILL REINFORCE THE MOISTURE MOVING INTO THESE AREAS.
WILL CONTINUE WARNINGS THROUGH NOON MONDAY.

WILL CONTINUE GRADUAL WARMING TREND THROUGH THE PERIOD AS WELL AS
THE INTRODUCTION OF RAIN AND SNOW INTO THE CENTRAL INNER
CHANNELS.  WINDS WILL ALSO REMAIN RELATIVELY LIGHT THROUGH THE
PERIOD.  THE OCCLUSION MOVING NORTH ACROSS THE PANHANDLE WILL
INTRODUCE LOW GALES INTO THE SOUTH.  SKAGWAY SHOULD CONTINUE TO
GUST AROUND 30 KT THROUGH THIS EVENING AND FALL OFF LATER
TONIGHT.

.LONG RANGE...
THE 12Z AK-GFS IS ACCEPTED THIS MORNING FOR THE MEDIUM RANGE AS A
GOOD COMPROMISE BETWEEN THE UKMET AND ECMWF. HPC CONCURS.

ALL MODELS AND MOST ENSEMBLE MEMBERS FORECAST THAT THE MAIN SFC
LOW WILL END UP IN THE WESTERN GULF MON NIGHT BUT DIFFER ON THE
DETAILS & TIMING OF A SECONDARY DEVELOPING LOW SOMEWHERE OFF THE
CHARLOTTES MON NIGHT AROUND 990 MB. FORTUNATELY THE MID SHIFTS
PRESSURE AND WIND FIELDS REFLECT THIS FEATURE SO WILL ONLY
INCREASE A FEW COASTAL WIND GRIDS TODAY. TIMING ON THIS MAY
DIFFER FROM RUN TO RUN AND THE 12Z AK-GFS A LITTLE FASTER THAN
PREVIOUS RUNS. CONFIDENCE MODERATE.

WILL CONTINUE WITH THE SCREAMING MESSAGE OF CONTINUED WET AND
WARMER TRENDS THANKS TO SIGNIFICANT SW FLOW ALF. DETAILS OF SNOW
VERSUS RAIN TUE AND WED ARE TRICKY FOR THE NORTH PART BUT ARCTIC
FRONT WILL BE N OF OUR AREA. WED STORM SYSTEM S OF KODIAK ISLAND
LOOKS CERTAIN AND WILL SEND A STRONG FRONT AND A BLAST OF WARMER
AIR TO SE AK WED AND THU. 12Z MODELS INSIST ON SOME COOLING NEXT
FRI AND SAT WITH A COLD FRONT THEN LOW LEVEL WESTERLIES ALSO AS
PER HPC SFC PROGS.

.AJK...WATCHES/WARNINGS/ADVISORIES
PUBLIC...HVY SNOW WARN...17-20-21-22-24-25 THRU 6 PM.
                         18-19-29 THRU NOON MONDAY.

...WARMING TREND TO CAUSE WATER PROBLEMS TUESDAY THROUGH THURSDAY...

ARCTIC AIR IS BEING WARMED AND MODIFIED INTO MARINE AIR IN SOUTHEAST
ALASKA AS A SERIES OF WARM FRONTS MOVE ONTO THE COAST. RISING
TEMPERATURES COMBINED WITH RAINFALL ON THE SNOW PACK WILL CAUSE
STANDING WATER TO FORM IN LOW LYING AREAS. DRAINAGE IN SOME
LOCATIONS WILL BE HAMPERED BY AN ICE LAYER WELL BELOW THE SURFACE.
EXPECT SOME LOCAL STREAMS TO BEGIN FLOWING WITH INCREASING WATER
LEVELS.

RAINFALL ON SNOW WILL INCREASE THE WEIGHT OF THE SNOW LOAD.
PERSONS SHOULD BEGIN TO REMOVE DEEP SNOW LAYERS FROM STRUCTURES
WHERE INCREASED LOAD MAY BE A PROBLEM. BOAT OWNERS ARE ADVISED TO
CLEAR SNOW FROM DECKS AND ENSURE THAT BILGE PUMPS ARE OPERABLE.
STANDING WATER THAT DEVELOPS ON ROADWAYS MAY ALSO BE A HAZARD.
SOME AREAS MAY EXPERIENCE FREEZE-THAW CYCLES WHERE STANDING WATER
REFREEZES.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE NEWS MEDIA FOR
UPDATES ON THIS SITUATION.
