AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PST THU JAN 2 2014

.SYNOPSIS...ONSHORE FLOW WILL FOLLOW A FRONT PUSHING EAST OF THE
CASCADES TONIGHT. SNOW WILL FALL IN THE MOUNTAINS LATE TONIGHT AND
FRIDAY MORNING. HIGH PRESSURE ALOFT WILL RESULT IN DRY WEATHER THIS
WEEKEND. WEAK WEATHER SYSTEMS WILL BEGIN MOVING THROUGH THE AREA
AGAIN BY TUESDAY.

&&

.SHORT TERM...AT 830 PM THE FRONT WAS PUSHING E OF PUGET SOUND AND
INTO THE CASCADES. RADAR INDICATES LIGHT TO MODERATE STRATIFORM
PRECIP STILL LAGGING BEHIND THE FRONT. SNOW LEVELS ARE BEGINNING TO
FALL AND WILL LOWER FURTHER THROUGH THE NIGHT. STEVENS PASS CHANGED
FROM RAIN OVER TO SNOW THIS PAST HOUR AND OVER SIX INCHES OF SNOW
ALREADY FELL AT MT BAKER SO THE ADVISORY WILL VERIFY IN THE N
CASCADES. THE SKI RESORTS SHOULD PICK UP 6 TO 9 INCHES...WITH
LOCALLY HIGHER AMOUNTS. RAIN AT SNOQUALMIE PASS WILL PROBABLY NOT
CHANGE OVER TO SNOW UNTIL AFTER MIDNIGHT SO PERHAPS JUST 2 TO 4
INCHES THERE BY FRIDAY MORNING...BELOW ADVISORY CRITERIA. THE WINTER
WEATHER ADVISORY THROUGH TONIGHT ABOVE 4000 FEET LOOKS GOOD WITH
JUST MINOR ADJUSTMENTS BEING MADE TO THE STATEMENT.

SATELLITE IMAGERY INDICATES THE BACK EDGE OF THE RAIN BAND IS
NEARING THE N COAST WITH RAIN TAPERING TO SHOWERS ACROSS THE
INTERIOR LOWLANDS AFTER MIDNIGHT. MODELS INDICATE PRECIP WILL SHUT
DOWN PRETTY QUICKLY WITH JUST SOME LINGERING SNOW SHOWERS IN THE
CASCADES FRIDAY MORNING. THE TROUGH MOVES E FRIDAY WITH A TRANSITION
TO DRIER WEATHER. MANY AREAS WILL SEE PARTIAL AFTERNOON SUNSHINE
WITH HIGH TEMPS IN THE MID 40S.

UPPER LEVEL HIGH PRESSURE BUILDS JUST OFF THE W COAST. A 1050+ MB
SURFACE HIGH DIVES SWD INTO IDAHO/MT. THIS WILL PROVIDE SOME
OFFSHORE FLOW ACROSS WRN WA. MODELS VARY ON THE STRENGTH OF THE
OFFSHORE GRADIENTS WHICH WILL MAKE A DIFFERENCE ON HOW MUCH FOG OR
LOW CLOUD DEVELOPS ACROSS THE LOWLANDS. IT WILL COOL DOWN SOME
ESPECIALLY AT NIGHT WITH MANY OUTLYING AREAS AND PORTIONS OF THE SW
INTERIOR FALLING INTO THE UPPER 20S. HIGHS AROUND THE AREA WILL BE
IN THE LOWER TO MID 40S WITH SOME AFTERNOON SUNSHINE MORE LIKELY
THAN NOT OVER THE WEEKEND. MERCER

.LONG TERM...FROM 300 PM DISCUSSION...MONDAY IS ALSO LIKELY TO BE
DRY. A WEAK WEATHER SYSTEM MAY BE APPROACHING THE COAST BY THE END
OF THE DAY. IT MOVES INLAND TUESDAY AND THAT SPELLS THE END OF
OFFSHORE SURFACE FLOW. THE EURO AND GFS HAD BEEN IN PHASE BUT NOW
APPEAR TO NOT BE. WEAK SYSTEMS ARRIVE EACH DAY IN ONE OR THE OTHER
OF THE MODELS SO HAVE CHANCE POPS THROUGHOUT AND SEASONAL TEMPS.
BURKE

&&

.HYDROLOGY...FLOODING IS NOT EXPECTED DURING THE NEXT 7 DAYS.

&&

.AVIATION...A VIGOROUS COLD FRONT AND ITS ASSOCIATED UPPER LEVEL
TROUGH IS MOVING THROUGH THE WESTERN WASHINGTON INTERIOR THIS
EVENING AND WILL PUSH WELL EAST OF THE CASCADES OVERNIGHT. A MOIST
AND STABLE AIR MASS AHEAD OF THE FRONT WILL BECOME SLIGHTLY UNSTABLE
BEHIND THE FRONT AND WILL DRY SOMEWHAT.

CONDITIONS AHEAD OF THE FRONT THIS EVENING ARE GENERALLY MVFR WITH
POCKETS OF IFR AROUND KSHN AND AROUND KPAE WHERE A PUGET SOUND
CONVERGENCE ZONE HAS FORMED. RADARS SHOW A SHARP BACK EDGE TO THE
FRONTAL PRECIPITATION AND SATELLITE IMAGERY AND LANGLEY HILL RADAR
SHOWS LITTLE IN THE WAY OF SHOWER ACTIVITY OFFSHORE. SO EXPECT
PRECIPITATION TO COME TO AN END THIS EVENING EXCEPT IN THE UPSLOPE
AREAS ALONG THE WEST SLOPES OF THE CASCADES AND IN THE CONVERGENCE
ZONE AREA FROM KPAE-KBFI...WHERE PRECIPITATION WILL LINGER UNTIL
ABOUT 15Z FRI. VIS WILL IMPROVE TO P6SM AS PRECIPITATION COMES TO AN
END AND CIGS BEHIND THE FRONT WILL BECOME BKN025 BKN-OVC050. THE
BKN025 DECK SHOULD SCATTER OUT BY 18Z AS HIGH PRES BUILDS TO THE
NORTH AND FLOW BECOMES NORTHERLY. ALBRECHT

KSEA...PRECIPITATION SHOULD COME TO AN END ABOUT 07Z. EXPECT
CONVERGENCE ZONE ACTIVITY TO STAY FROM KBFI NORTHWARD. S TO SW WIND
10-14 KT ARE EXPECTED TO GRADUALLY EASE TO SE 5 KT AFTER 10Z.
ALBRECHT

&&

.MARINE...A COLD FRONT IS MOVING THROUGH THE INLAND WATERS THIS
EVENING AND WILL PUSH WELL EAST OF THE CASCADES OVERNIGHT. NEAR GALE
FORCE WESTERLY WINDS HAVE DEVELOPED IN THE CENTRAL AND EAST ENTRANCE
TO THE STRAIT...AND GALE FORCE WINDS AT TIMES ARE EXPECTED TO
CONTINUE THERE UNTIL ABOUT 4 AM. NW WINDS 15 TO 25 KT ARE EXPECTED
TO DEVELOP OVER THE REMAINING WATERS BEHIND THE FRONT...EXCEPT IN
THE PUGET SOUND AND HOOD CANAL AREA FROM ABOUT SEATTLE SOUTHWARD.
WINDS WILL GRADUALLY RELAX FRI MORNING AND TURN NORTHERLY AS HIGH
PRES DEVELOPS OVER SOUTHWEST BRITISH COLUMBIA.

LIGHT TO MODERATE OFFSHORE FLOW IS EXPECTED SAT TROUGH EARLY NEXT
WEEK AS HIGH PRES DOMINATES EAST OF THE CASCADES AND LOWER PRES
REMAINS OFFSHORE. ALBRECHT
