What happened

The episode as NWS AJK wrote it up.

The arctic front persisted over the Central Panhandle on Tuesday, January 23rd. A series of weak Lows over the Southern and Central Gulf of Alaska continued to push warm air over the arctic front. Upslope conditions enhanced the snow in the Northern Panhandle. Cold air was trapped in the Misty Fjords near Hyder at this time.

SOUTHEAST ALASKA FORECAST DISCUSSION
1100 AM AST TUE JAN 23 2007

.SYNOPSIS...
.SHORT RANGE...12Z MODELS LOOK TO BE IN FAIR COMPARISON WITH
SATELLITE AND OBSERVATIONS ACROSS THE AREA. LOOKS AS IF INITIAL
FRONTAL BAND HAS LIFTED THROUGH THE NORTHERN PANHANDLE AND SECOND
WAVE OF ENERGY WILL BE MOVING ACROSS THE SOUTHERN PANHANDLE
TUESDAY AFTERNOON AND THE CENTRAL PANHANDLE THROUGH TUESDAY
NIGHT.

WARM UP ACROSS THE CENTRAL PANHANDLE PROGRESSING WITH ANGOON NOW
SWITCHED OVER TO RAIN...STILL EXPECT TO SEE THE JUNEAU AREA DO
THAT AS WELL LATER THIS AFTERNOON. THE HEAVIER PRECIPITATION FOR
THE ZONES OF 20 21 AND 25 HAVE TAPERED OFF SO WILL CANCEL THE
SNOW ADVISORIES FOR THOSE AREA BEFORE NOON. YAKUTAT AREA STARTING
TO MIX WITH RAIN AS WELL NOW...EXCEPT FOR FAR WEST OF THE ZONE
WHICH WILL LIKELY STAY SNOW... SO WILL CANCEL SNOW ADVISORY THAT
IS OUT THERE AS WELL.

TEMPERATURES OVER THE NORTH CENTRAL INNER CHANNEL ZONES TONIGHT
STEADY IN THE LOWER 30S OR SLOWLY CLIMBING TO THE NEAR 35 BY
MORNING...SO A WILL MAINTAIN A MIX OR ALL SNOW HEADED TO A
MIX...DEPENDING ON LOCATION. SOME OF THE LONE EXCEPTIONS TO THE
MIX PART WOULD BE NORTHERN GLACIER BAY VALLEYS AND SOME TAKU
INLET AREA CANADIAN PASSES...SUSPECT THAT THEY WILL CONTINUE TO
SNOW INTO WEDNESDAY BEFORE FINALLY CHANGING THE PRECIPITATION
TYPE.

NORTHERN LYNN CANAL AREA SHOULD STAY ALL SNOW AND EXPECT TO SEE
AREA AROUND HAINES ACCUMULATE UP TO ABOUT A FOOT OF SNOW BY EARLY
WEDNESDAY BEFORE IT SWITCHES OF A MORE SHOWERY PATTERN.

SHOULD SEE A BURST OF WIND ACROSS THE NORTHERN PANHANDLE REGION
ON WEDNESDAY AS THE SURFACE LOW FINALLY JUMPS FULLY INTO THE
YUKON AND ALL OF THE NORTH GRADIENT PASSES OPEN UP.

.LONG RANGE...THE UPPER LEVEL LONGWAVE TROUGH OVER THE GULF OF AK
IS EXPECTED TO MOVE THROUGH SOUTHEAST ALASKA BY WED NIGHT AS AN
UPPER RIDGE REPLACES IT IN THE GULF. ON THU...A DEEPENING UPPER
TROUGH OVER THE ALEUTIANS PUSHES THE RIDGE EASTWARD OVER THE
PANHANDLE WHERE IT REMAINS NEARLY STATIONARY AND SLOWLY BUILDS
THROUGH THE MIDDLE OF NEXT WEEK. THIS PATTERN ALOFT ALLOWS A
SERIES OF SURFACE LOWS TO DEVELOP IN THE PACIFIC AND MOVE
NORTHWARD INTO THE WESTERN GULF OF ALASKA THROUGH EARLY NEXT
WEEK. THE ENSEMBLE SPREAD IS GREATEST IN THE WESTERN GULF WITH
EACH OF THESE SYSTEMS. FRONTAL SYSTEMS ASSOCIATED WITH THE LOWS
WILL WEAKEN AS THEY CROSS THE GULF AND DISSIPATE NEAR THE
NORTHERN SOUTHEAST ALASKA COAST.

PRECIPITATION INCREASES OVER THE NORTHEAST GULF FRI AND THE
NORTHERN PANHANDLE ARE EXPECTED FRI NIGHT AND SAT WITH THE FIRST
FRONT AND THEN AGAIN ON SUN WITH THE NEXT. SOUTHERN SOUTHEAST
ALASKA WILL MAINTAIN LOW PROBABILITIES UNDER THE INFLUENCE OF THE
RIDGE. MOST OF THE SIGNIFICANT WINDS WILL BE WEST OF THE AREA
WITH THESE LOWS WITH BRIEF MODERATE INCREASES IN THE EASTERN GULF
IN THE VICINITY OF THE THE WEAKENING FRONTS.
