.DISCUSSION...ANOTHER RAINY DAY ACROSS THE CWA THIS AFTERNOON. AT
THIS TIME OFFICIAL EUREKA RAINFALL SHOWS THE WE ARE APPROACHING THE
9TH WETTEST MARCH IN HISTORY DATING BACK TO 1887.  A DYING FRONT
CURRENTLY DROPPING RAIN ACROSS THE WESTERN HALF OF THE CWA HAS
DROPPED ABOUT 13 HUNDREDTHS AT WOODLEY ISLAND.  IT WAS A TRICKY
AFTERNOON AS RAINFALL WAS VERY LATE TO BEGIN AND MODELS INSISTED
THAT GREATER AMOUNTS WOULD BE CAUGHT.  BUT SATELLITE AND RADAR
IMAGERY CONFLICTED WITH MODEL GUIDANCE SHOWING THE FRONT NEARLY
STALLING AND FALLING APART AS IT APPROACHED THE COAST. BEHIND THIS
SYSTEM VISIBLE IMAGERY SUGGESTS SOME CLEARING THAT MAY PREVAIL
BRIEFLY LATER TONIGHT.  BUT ANOTHER STRONGER IMPULSE IS EXPECTED TO
ROUND THE BASE OF THE TROUGH EARLY FRIDAY MORNING BRINGING ANOTHER
ROUND OF RAINFALL AND SNOW TO THE REGION.  SNOW LEVELS WILL DROP TO
3500 FEET TONIGHT AND LESS THAN 3000 FEET BY FRIDAY NIGHT...AS THE
COLDER CORE OF THE UPPER TROUGH APPROACHES THE AREA.  700 MB
TEMPERATURES ARE FORECAST AT AROUND -10C FOR TONIGHT AND ARE
FORECAST TO DROP TO -12C BY FRIDAY NIGHT   THE BEST PRECIPITATION
AMOUNTS WITH OROGRAPHICS WILL BE NEAR THE COAST. THE MODELS GENERATE
ANOTHER GULF OF ALASKA UPPER LOW ON FRIDAY...DROP IT SOUTHEAST...AND
MOVE IT ACROSS THE FORECAST AREA TUESDAY.  RAIN IS FORECAST TO
DEVELOP WITH THIS FEATURE SUNDAY NIGHT AND CONTINUE INTO ON AND OFF
INTO WEDNESDAY.  SHORT WAVE RIDGING IS FORECAST WEDNESDAY AND
THURSDAY AHEAD OF THE THE NEXT FORECAST SYSTEM.

&&

.AVIATION...BANDS OF PRECIPITATION ROTATING AROUND A LOW PRESSURE
SYSTEM IN THE NORTHEAST PACIFIC WILL CONTINUE TO AFFECT THE CWA
TONIGHT. EXPECT BOUTS OF MVFR WITH BRIEF IFR CONDITIONS UNDER THE
MORE INTENSE SHOWERS. THE LOW WILL PROGRESS EASTWARD TOWARD THE
OREGON COAST THROUGH FRIDAY WITH RAIN EXPECTED TO KEEP THINGS WET
ACROSS THE REGION THROUGH FRIDAY NIGHT.
