SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
332 PM AKDT SUN MAR 27 2016

.SHORT TERM...A TROUGH OF LOW PRESSURE PUSHING EAST HAS RESULTED
IN MOSTLY CLOUDY SKIES AND SCATTERED SHOWERS TODAY. SHOWER
ACTIVITY HAS MAINLY BEEN FOCUSED ACROSS THE NORTHERN HALF OF THE
PANHANDLE WITH MORE BREAKS OF SUN ACROSS SOUTHERN AREAS. A WEAK
AREA OF LOW PRESSURE OVER THE NORTHEAST GULF COMBINED WITH THE
BUILDING RIDGE TO THE SOUTH HAS GENERATED STRONG WESTERLIES ALONG
THE OUTER COAST TODAY WITH CROSS SOUND NEARING GALE FORCE AND
GUSTY WINDS AT CAPE DECISION. THESE WINDS WILL TRANSLATE TO THE
NORTHERN INNER CHANNELS AS THE WEAK LOW MOVES INLAND EARLY THIS
EVENING. ADDITIONALLY, STRONG SOUTHWEST FLOW HAS RESULTED IN
LEE SIDE TROUGHING OVER THE FAR NORTHERN PANHANDLE WITH STRONG
SOUTHERLY WINDS IN SKAGWAY AND LYNN CANAL.

A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE SOUTHEASTERN GULF
AND SOUTHERN PANHANDLE TONIGHT AND MONDAY. THE NEXT BIG WEATHER
MAKER WILL BE A FRONT MOVING INTO THE NORTHEAST GULF AND NORTHERN
PANHANDLE LATE TONIGHT THROUGH MONDAY. THIS FRONT WILL HAVE AN
IMPRESSIVE STREAM OF MOISTURE AS MODELS INDICATE PRECIPITABLE
WATER BETWEEN 0.8 TO 0.9 INCHES OVERSPREADING THE AREA. THESE
VALUES ARE 3 STANDARD DEVIATIONS ABOVE NORMAL FOR THIS TIME OF
YEAR. FAVORABLE SOUTHWEST 850 MB FLOW...MOISTURE TRANSPORT...AND
STRONG WARM AIR ADVECTION WILL ALSO INCREASE THE LIKELIHOOD OF
HEAVY RAIN. EXPECT THE RAINFALL TO BECOME HEAVY AT TIMES LATE
TONIGHT NEAR YAKUTAT AND SPREAD SOUTH AND EAST ON MONDAY. 6 HOURLY
RAINFALL AMOUNTS WILL RANGE FROM 0.50-0.75 INCHES ON THE OUTER
COAST FROM ELFIN COVE TO YAKUTAT. 0.25-0.40 INCHES EVERY 6 HOURS
IS EXPECTED OVER THE NORTHERN INNER CHANNELS ON MONDAY. NO
FLOODING IS ANTICIPATED AT THIS TIME BUT REFER TO THE SPS PRODUCT
ISSUED FOR MORE INFORMATION ON THIS UPCOMING HEAVY RAIN EVENT.
WITH RIDGING NOSING INTO THE SOUTHERN PANHANDLE POPS REMAIN BELOW
50 PERCENT THROUGH MONDAY WITH THE FAR SOUTHERN PANHANDLE EXPECTED
TO STAY DRY. WINDS WILL BE GENERALLY 15-20 KT OVER THE INNER
CHANNELS ON MONDAY WITH THE STRONGEST WINDS IN LYNN CANAL WHERE A
SOUTHERLY SMALL CRAFT IS ANTICIPATED.

USED ON THE HIRES ARW AND NMM FOR UPDATES TO THE FORECAST THROUGH
THE FIRST 24 HOURS. FORECASTER CONFIDENCE IS ABOVE AVERAGE.

.LONG TERM...MOISTURE CONTINUES TO STREAM OVER THE NORTH SIDE OF
THE RIDGE ALONG THE PANHANDLE. EXPECT RAIN TO CONTINUE OVER THE
NORTHERN PART OF THE PANHANDLE INTO TUESDAY AFTERNOON AND WILL
TAPERING OFF TUESDAY NIGHT FROM THE SOUTH. DO EXPECT TO SEE THE
RAINS TO DIMINISH ALONG THE NORTHEAST GULF COAST AS THE UPPER
UPPER LEVEL RIDGE BUILDS NORTH OVER THE EASTERN GULF OF ALASKA AND
SOUTHEAST ALASKA.

THE RIDGE SHOULD CLEAR OUT THE PANHANDLE LATE WEDNESDAY TO
THURSDAY... AND THE SOUTHERN PANHANDLE TO PERHAPS FRIDAY. THERE IS
A GOOD SOUTHERLY FLOW PATTERN SO STILL EXPECTING THE BIG PUSH OF
WARM AIR INTO THE EASTERN GULF AND SOUTHEAST ALASKA THURSDAY TO
FRIDAY. DEPENDING ON THE MODEL SOLUTIONS 850 MB TEMPERATURES ARE
+8 TO +12C OVER THE AREA.

MODEL CONSENSUS STILL GOOD THROUGH WEDNESDAY NIGHT AND THE NEWER
WPC SOLUTION DOVE-TAILED INTO IT AS WELL SO THERE WAS A SMOOTH
TRANSITION INTO THE LONG RANGE FORECAST PERIODS. MADE MINOR
CHANGES IN THE EARLIER FORECAST TIME FRAMES BUT ESSENTIALLY
CONTINUED THINKING OF THE PREVIOUS SHIFT.

EXTENDED THE STRONG WIND HEADLINE IN THE SKAGWAY AREA THROUGH
MONDAY NIGHT WITH INCREASED GRADIENT FROM THE BUILDING SURFACE
RIDGE IN THE AREA. COULD HAVE POSSIBLY CARRIED IT EVEN FURTHER
BUT DID NOT EXTEND INTO TUESDAY.
