NWS Forecaster Discussion



AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
322 AM PDT SAT AUG 30 2014

.SYNOPSIS...COOLER WESTERLY FLOW ALOFT PREVAILS THROUGH THIS
WEEKEND..WITH A SERIES OF WEAK SURFACE FRONTS. THIS WILL BRING 
PLENTY OF CLOUDS AND COOLER AIR TO THE REGION...ALONG WITH PERIODIC 
RAIN SHOWERS. THE BEST CHANCES OF SHOWERS WILL BE THIS AFTERNOON AND 
EVENING. WEAK RIDGING TRIES TO BUILD BACK INTO THE PACIFIC 
MONDAY...BEFORE A DEEPER TROUGH MOVES OVER THE AREA TUESDAY THROUGH 
THE END OF THE WEEK.

&&

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...RADAR AND SURFACE
OBSERVATIONS HAVE DETECTED LIGHT RAIN SHOWERS ALONG THE NORTHERN
OREGON COAST EARLY THIS MORNING...AS AN UPPER LEVEL SHORTWAVE
TROUGH...CURRENTLY AROUND 50 MILES OFFSHORE...APPROACHES. AT THE
SURFACE...A WEAK FRONT IS APPROACHING THE WASHINGTON AND OREGON COAST
AND WILL MOVE ACROSS THE PORTLAND FORECAST AREA THIS
AFTERNOON...SPREADING LIGHT RAIN WITH IT. SATELLITE DERIVED TROPICAL
PRECIPITABLE WATER SHOWS TPW GREATER THAN AN INCH. THIS MOISTURE
COMBINED WITH A 122KT UPPER LEVEL JET NOSING INTO SW
OREGON...PROVIDES A GREAT CHANCE FOR MEASURABLE RAIN ACROSS NW OREGON
AND SW WASHINGTON TODAY...AND HAVE INCREASED POPS.

RAIN SHOWERS ALONG THE COAST WILL SHIFT INLAND THROUGH THE DAY AND
HANG UP OVER THE CASCADES IN THE EVENING. LINGERING MOISTURE AND CALM
WINDS WILL LIKELY RESULT IN FOG DEVELOPING OVERNIGHT TONIGHT INTO
SATURDAY MORNING.  THINK THE BEST CHANCE FOR FOG WILL BE ALONG THE
COAST...BUT CAN NOT RULE OUT THE POSSIBILITY FOR FOG IN PARTS OF THE
NORTHERN AND CENTRAL WILLAMETTE VALLEY. 

ANOTHER WEAK FRONT WILL MOVE ACROSS THE AREA SUNDAY. THE CHANCE FOR
RAIN IS WEAKER WITH THIS SYSTEM AS THE UPPER JET SHIFTS
NORTHWARD...AND REDUCED ATMOSPHERIC LIFT. THE PRECIPITATION ON
SUNDAY WILL BE VERY LIGHT...POSSIBLY MORE DRIZZLE THAN RAIN AND BE
RESTRICTED TO AREAS NORTH OF SALEM.  

AN UPPER RIDGE WILL BUILD MONDAY...BUT THE MODELS HAVE BEEN BACKING
OFF ON THE STRENGTH OF THE RIDGE AND EXPECT ANOTHER WEAK FRONT TO
CLIP THE NORTHERN AREAS MONDAY AFTERNOON AND EVENING. TJ

.LONG TERM...A FLAT UPPER LEVEL RIDGE WILL DEVELOP OVER THE PACIFIC
NW TUESDAY...BEFORE A DEEPER TROUGH OVER WESTERN CANADA SLIDES
SOUTHWARD ALONG THE COAST....PUTTING ANOTHER UPPER TROUGH OVER THE
REGION TUESDAY NIGHT. SHORTWAVES MOVING AROUND THE TROUGH WILL KEEP
GENERAL TROUGHINESS OVER THE AREA THROUGH NEXT WEEKEND. TEMPERATURES 
WILL GENERALLY BE NEAR SEASONAL NORMALS.

&&

.AVIATION...A FEW LIGHT SHOWERS ARE MOVING INLAND FROM THE COAST
AT 09Z. LIGHT SHOWERS ARE EXPECTED THROUGH THE DAY...THEN DECREASE
THIS EVENING. AT THE COAST...MUCH OF THE LIFR CONDITIONS HAVE
ENDED AS THE SHOWERS ARRIVED WITH A MIX OF LOW MVFR TO VFR. IT IS
LIKELY THIS TREND OF MVFR TO VFR WILL CONTINUE THROUGH THE
DAY...THEN TREND TOWARD MORE MVFR THIS EVENING INTO SUNDAY.
INLAND AREAS...MAINLY VFR TODAY WITH OCCASIONAL MVFR CIGS AROUND
1500-2500 FT MAINLY AROUND THE LOWER COLUMBIA RIVER TO NEAR KPDX
THIS MORNING.

KPDX AND APPROACHES...VFR CONDITIONS WITH CIGS IN THE 5000-7000 FT
RANGE ALONG WITH SOME LIGHT SHOWERS ESPECIALLY IN THE AFTERNOON
HOURS. 1300 FT CIGS REACHED KLS AT 09Z SAT AND THE WEAK ONSHORE
FLOW MAY BE ENOUGH TO PUSH IT INTO THE PDX AREA SO WILL ADD A
PERIOD WITH CIGS OF 1500-2000 FT 12Z-17Z.

&&

.MARINE...ANOTHER WEAK FRONT WILL MOVE ACROSS THE WATERS TODAY AND
A THIRD...POTENTIALLY STRONGER FRONT SUNDAY AFTERNOON AND NIGHT.
THE SEAS WILL COMPRISE OF A SMALL SW SWELL OF 1 TO 2 FEET AT
AROUND 15 SECONDS AND A NORTHWEST FRESH SWELL FROM THE GULF OF
ALASKA AROUND 9 TO 10 SECONDS. LIGHT WIND WAVES THE NEXT COUPLE OF
DAYS. A NW SWELL WILL BUILD TONIGHT AND PEAK AROUND 6 FEET ON
SUNDAY. HIGH PRESSURE WILL REBUILD MONDAY NIGHT AND TUESDAY AND
PERSISTENT NORTHERLY WINDS WILL RETURN TO THE WATERS.
