AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE EUREKA CA
425 PM PDT THU APR 17 2014

.SYNOPSIS...A WEAK FRONT WILL BRING LIGHT RAIN SHOWERS TO AREAS
MAINLY NORTH OF CAPE MENDOCINO THIS EVENING. HIGH PRESSURE SHOULD
BRING DRIER WEATHER ON FRIDAY FOLLOWED BY ANOTHER SHOT OF LIGHT
RAIN ALONG THE REDWOOD COAST ON SATURDAY. A STRONGER STORM SYSTEM
WILL IMPACT NORTHWEST CALIFORNIA WITH WIDESPREAD RAIN AND MOUNTAIN
SNOW THE FIRST HALF OF NEXT WEEK.

&&

.DISCUSSION...22Z RADAR SHOWS A LINE OF RAIN MOVING FROM WEST TO
EAST ACROSS NORTHWEST CALIFORNIA. THIS IS ASSOCIATED WITH A WEAK
FRONT THAT IS CURRENTLY CROSSING OUR AREA. ADDITIONAL RAINFALL
AMOUNTS SHOULD BE LOW. THE SHOWERS WILL DISSIPATE THIS EVENING AND
OVERNIGHT AS THE FRONT MOVES INLAND. HIGH PRESSURE WILL BUILD ON
FRIDAY, BRINGING DRIER WEATHER. ANOTHER WEAK FRONT IS EXPECTED TO
GRAZE THE AREA ON SATURDAY WITH EVEN LIGHTER QPF AMOUNTS, MAINLY
ACROSS THE REDWOOD COAST. BUMPED UP POPS SLIGHTLY IN THESE
LOCATIONS TO REFLECT THE BETTER MODEL AGREEMENT. IT ALSO LOOKS TO
BE A SITUATION WHERE WE WILL HAVE A HIGH PROBABILITY OF LOW
PRECIPITATION. FOLLOWING THIS FRONT, MODELS ARE COMING INTO BETTER
AGREEMENT WITH A DIGGING TROF OVER THE W UNITED STATES DURING THE
FIRST HALF OF NEXT WEEK. THIS WILL BRING WIDESPREAD PRECIP WITH
RAINFALL TOTALS OF AN INCH OR MORE POSSIBLE IN THE N. SNOW LEVELS
WILL FALL SIGNIFICANTLY WITH THIS SYSTEM AS IT DIGS AND SHIFTS E.
BUT IT`S STILL TOO EARLY TO TELL HOW LOW AND WHAT THE SNOWFALL
AMOUNTS COULD BE. AGAIN, BUMPED UP POPS TO REFLECT THE BETTER
MODEL AGREEMENT AND CONFIDENCE.
