SYNOPSIS...
KEY MESSAGES:
- OUR BREAK FROM THE RAIN WILL COME TO AN END ON SUNDAY.
- A GALE FORCE FRONT WITH WINDS 35 KT TO 45 KT MOVES INTO THE
NORTHEASTERN GULF OF ALASKA SUNDAY. GALE WARNINGS ARE POSTED FOR
THE OPEN GULF NORTH OF 57 DEGREES NORTH LATITUDE AND FROM CAPE
SPENCER NORTH THROUGH CAPE SUCKLING.
SHORT TERM.../THROUGH MONDAY/...OUR SHORT STINT OF DRIER WEATHER
TODAY COMES TO AN END BY TOMORROW AS A GALE FORCE FRONT OVER THE
GULF WORKS NORTHEASTWARD...BRINGING A SWATH OF WIDESPREAD RAIN TO
SE ALASKA SUNDAY INTO MONDAY. NO BIG CHANGES WERE MADE ON THE
DAY SHIFT PRODUCTS, KEEPING RAINFALL AMOUNTS ACROSS SE ALASKA
GENERALLY IN THE HALF INCH OR LESS CATEGORY...NOT ENOUGH FOR A
SIGNIFICANT HYDROLOGIC RESPONSE FOR FLOODING ISSUES. IT WILL BET
BREEZY ALONG THE OUTER COAST, ALTHOUGH NOT TO WIND ADVISORY
CRITERIA. MAIN IMPACTS FROM THE FRONT OVER THE GULF TONIGHT INTO
SUNDAY WILL BE ACROSS THE MARINE AREA...AND MAINLY OFFSHORE.
/GARMON
LONG TERM.../TUESDAY THROUGH FRIDAY/...
MOISTURE LINGERING FROM MONDAY'S PRECIPITATION LOOKS TO STICK
AROUND THE NORTHERN PANHANDLE THROUGH THE DAY ON TUESDAY,
BRINGING CLOUDY SKIES AND CHANCES FOR RAIN. HOWEVER, THE CENTRAL
AND, ESPECIALLY SOUTHERN PANHANDLE WILL SEE MORE CLEARING THOUGH
THE DAY TUESDAY BEFORE ANOTHER FRONT MOVES ACROSS THE AREA EARLY
OR MID WEDNESDAY MORNING. THIS WILL BRING MORE WIDESPREAD RAIN TO
THE PANHANDLE, WITH HIGHER ACCUMULATION TOTALS AIMED AT THE
NORTHERN PANHANDLE, MAINLY YAKUTAT AND JUNEAU. RAIN IS ANTICIPATED
TO DIMINISH AGAIN THROUGH THE DAY THURSDAY ACROSS THE ENTIRE
PANHANDLE WHICH ALSO BRINGS THE CHANCE FOR CLEARING SKIES GOING
INTO LATE NEXT WEEK. /PEREZ
AVIATION...CLOUD COVER CONTINUES TO INCREASE THIS EVENING AS
CLOUDS FROM THE NEXT SYSTEM WORK CLOSER TO THE PANHANDLE. SOME
PERIODS OF MVFR CEILINGS HAVE BEEN REPORTED THIS EVENING AROUND
THE SITKA AREA. VFR CEILINGS ARE EXPECTED TO PERSIST THROUGH MOST
OF THE OVERNIGHT HOURS BEFORE THE RAIN MOVES CLOSER TO THE OUTER
COAST AND WE START TO SEE CEILINGS DROP DOWN MVFR CONDITIONS. AS
THE RAIN SPREADS ACROSS THE PANHANDLE, SOME VISIBILITY DROPS DOWN
TO MVFR ARE POSSIBLE. WITH THE FRONT MOVING CLOSER TO THE COAST,
SOME AREAS OF LLWS WILL BE POSSIBLE DURING THE DAYTIME HOURS
TOMORROW STARTING AROUND MID MORNING AND LASTING THROUGH THE
AFTERNOON. HEADING INTO THE LATTER HALF OF THE TAF PERIOD, SOME
CEILINGS COULD DROP DOWN TO IFR NEAR THE EVENING HOURS.
MARINE...NO BIG CHANGES WERE MADE FOR THE AFTERNOON MARINE
FORECAST ISSUANCE. WE STILL EXPECT TO SEE THE GALE FORCE FRONT TO
MOVE NORTHEAST INTO THE NORTHEASTERN GULF TONIGHT INTO SUNDAY.
STRONGEST SUSTAINED WINDS 35-45 KT AND SEAS 15 TO 20 FT ARE STILL
EXPECTED FROM CAPE CAPE SUCKING TO JUST OFF CAPE SPENCER AND
NORTH OF THE 57TH PARALLEL. OVER THE INSIDE WATERS, WE GENERALLY
EXPECT LESS OF A PRESSURE GRADIENT AND WINDS, ALTHOUGH INCREASED
GENERAL SOUTHWEST TO SOUTHEASTERLY FLOW IS EXPECTED BY SUNDAY
LINGERING INTO MONDAY BEFORE THE FRONT DISSIPATES. ANOTHER FRONT
MOVES ACROSS THE GULF ON WEDNESDAY, HOWEVER WINDS SPEEDS LOOK TO
BE LESS...GENERALLY 25 TO 30 KTS MAX. /GARMON
