AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PDT FRI APR 15 2011

.SYNOPSIS...A WEAK LOW MOVING NORTHEAST ACROSS SOUTHWEST WASHINGTON
THIS EVENING WILL PUSH EAST OF THE CASCADES AFTER MIDNIGHT. FLOW
WILL BECOME ONSHORE LATE TONIGHT THROUGH SUNDAY. THE ONSHORE FLOW
WILL GIVE A CHANCE OF SHOWERS...MAINLY TO THE MOUNTAINS AND TO THE
CENTRAL PUGET SOUND AREA IN A CONVERGENCE ZONE. THE ONSHORE FLOW
WILL CONTINUE INTO EARLY NEXT WEEK. AN UPPER RIDGE MAY BUILD TOWARD
THE END OF NEXT WEEK.

&&

.SHORT TERM...SURFACE OBSERVATIONS AND MODELS SHOW A VERY WEAK 1013
MB LOW OVER THE WILLAPA HILLS AT 03Z THAT IS MOVING NE. EXPECT THIS
FEATURE TO DEVELOP INTO EASTERN WASHINGTON AFTER MIDNIGHT WITH LOW
LEVEL ONSHORE FLOW GRADUALLY INCREASING. PRECIPITATION TO THE NORTH
OF THIS LOW HAS BEEN QUITE LIGHT AND SPOTTY. LATEST 00Z NAM12
GUIDANCE SHOWS LIGHT PRECIPITATION BECOMING SHOWERY IN NATURE AND
TIED TO THE TERRAIN AS THE FLOW GOES ONSHORE AND UPPER LEVEL
WESTERLY FLOW COMBINED WITH A DECREASE IN STABILITY. THE 00Z NAM12
SOLUTION CONTINUES TO ADVERTISE SHOWERS ALSO FOCUSED AROUND A
CENTRAL PUGET SOUND CONVERGENCE ZONE SATURDAY. BASED ON THE CLOUD
COVER AND SHIFT TO ONSHORE FLOW TONIGHT...INCREASED MIN TEMPERATURES
OVERNIGHT A FEW DEGREES ALL ZONES.

ONSHORE FLOW INCREASES MORE SAT AFTERNOON AND SAT EVENING AS HIGH
PRES OVER THE OFFSHORE WATERS COMBINED WITH LOWER PRES E OF THE
CASCADES AND SOME DIFFERENTIAL HEATING BETWEEN LAND AND SEA. AFTER A
BIT OF A RELAXATION IN ONSHORE FLOW SUN MORNING...ANOTHER UPPER
LEVEL TROUGH DEVELOPING ALONG THE COAST WILL INCREASE WESTERLY
GRADIENTS ONCE AGAIN SUN NIGHT INTO MON. THE NAM12 LOOKS PRETTY DRY
AFTER SAT EVENING. HOWEVER THE LOW HEIGHTS ALOFT...CONTINUED ONSHORE
FLOW...AND THE LIKELY PRESENCE OF A CONVERGENCE ZONE SOMEWHERE
AROUND CENTRAL PUGET SOUND MEANS THAT A CHANCE OF SHOWERS CANNOT BE
RULED OUT. TEMPERATURES WILL CONTINUE SEVERAL DEG BELOW NORMAL
THROUGH THE WEEKEND. ALBRECHT

.LONG TERM....PREVIOUS LONG TERM DISCUSSION FOLLOWS. A COOL UPPER
TROUGH IS OVER THE PACNW THRU THE FIRST HALF OF NEXT WEEK...KEEPING
A CHANCE OF SHOWERS IN THE FCST. THERE IS A MORE ORGANIZED SYSTEM
LIKELY TO GO TO THE SOUTH OF WA ARND NEXT WED NITE OR THU...AND THEN
A WEAK RIDGE BUILDS SOMEWHAT FOR THU AND FRI. I PUSHED THE TEMPS UP
A NOTCH AND TOOK OUT THE CHANCE OF SHOWERS FOR MOST OF WRN WA FOR
THU/FRI. 19

&&

.AVIATION...MOIST...WLY FLOW ALOFT WILL PERSIST OVER THE REGION
OVERNIGHT. LOW LEVEL OFFSHORE OR NLY FLOW WILL ALSO CONTINUE.
ANTICIPATE LIGHT PRECIP OVER THE AREA...WHICH WILL RESULT IN AREAS
CIGS/VSBYS BELOW 1K FT/2-4SM. OTHERWISE CIGS SHOULD GENERALLY BE IN
THE 1500 TO 2500 FT RANGE OVERNIGHT.

KSEA...CIGS WILL LOWER TO NEAR 2500 FT OVERNIGHT...WITH OCCASIONAL
CIGS NEAR 1500 FT AFTER 1200 UTC. ANTICIPATE OFF AND ON LIGHT
PRECIP OVERNIGHT...WITH THE VSBYS OCCASIONALLY BEING REDUCED TO
ABOUT 5 NM. WINDS WILL REMAIN LIGHT AND VARIABLE.

&&

.MARINE...
A SURFACE LOW OFF THE SW WASHINGTON COAST WILL WEAKEN OVERNIGHT.
EXPECT THE FLOW TO BECOME ONSHORE ON SATURDAY AND THEN INCREASE
SATURDAY NIGHT AS A SURFACE HIGH BUILDS OVER THE OFFSHORE WATERS.
ONSHORE FLOW WILL THEN PERSIST THROUGH EARLY NEXT.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
PZ...GALE WATCH REMAINS IN EFFECT FOR THE CENTRAL AND EASTERN
      STRAIT OF JUAN DE FUCA SATURDAY EVENING.
