&&

.PREV DISCUSSION...ISSUED 349 PM PDT SUN MAY 26 2013...PARTLY
CLOUDY SKIES THIS AFTERNOON WILL BE REPLACED BY EXPANDING CLOUD
COVER THIS EVENING AHEAD OF A STRONG LATE SEASON STORM. A DEEP
MOISTURE PLUME IS EVIDENT ON WATER VAPOR AND IN THE BLENDED TOTAL
PRECIPITABLE WATER SATELLITE PRODUCT AND THE VALUES IN THIS
PRODUCT LINE UP WELL WITH THE GFS. THUS CONFIDENCE IS NOW HIGH IN
CONSIDERABLE RAINFALL TOTALS FOR LATE MAY WITH ALL MODELS
INDICATING OVER TO AROUND AN INCH OF QPF FOR THE DEL NORTE COUNTY
AREA. AS THIS SYSTEM AND MOISTURE REACH THE COAST RAIN WILL
DEVELOP FROM NORTH TO SOUTH OVERNIGHT INTO MONDAY. WIDESPREAD
RAINFALL TOTALS OF BETWEEN A QUARTER OF AN INCH TO UP TO AN INCH
ARE EXPECTED WITH LOCALLY HIGHER AMOUNTS IN THE MOUNTAINS OF DEL
NORTE AND HUMBOLDT COUNTIES. THE CURRENT FORECAST CALLS FOR NEARLY
AN INCH OF RAIN FOR CRESCENT CITY BUT AT LEAST ONE MODEL IS
INDICATING THERE IS THE POSSIBILITY OF TOTALS UP TO AN INCH AND A
HALF. THE RECORD RAINFALL FOR THE DATE IS 1.49 INCHES IN CRESCENT
CITY...SO THIS RECORD COULD BE APPROACHED. OTHER RECORDS FOR THE
DATE ARE 1.14 INCHES IN EUREKA AND 2.10 INCHES AT UKI WHICH AT
THIS TIME ARE NOT EXPECTED TO BE REACHED... ESPECIALLY UKI WHERE
THE FORECAST RAINFALL IS ONLY 0.30 INCHES.

A COLD FRONT WILL MOVE THROUGH THE REGION DURING THE DAY MONDAY
PUSHING THE GREATEST MOISTURE SOUTH OF THE REGION BY LATE MONDAY
AFTERNOON BRINGING AN END TO THE HEAVIEST RAINFALL. SOME SHOWERS
WILL CONTINUE THROUGH MONDAY NIGHT BEFORE WEAK RIDGING ALOFT BUILDS
OVERHEAD. THIS SHOULD END RAINFALL BY TUESDAY MORNING FOR MOST
LOCATIONS. ANOTHER SHORTWAVE TROUGH WILL MOVE TOWARD THE COAST
TUESDAY NIGHT INTO EARLY WEDNESDAY BRINGING ONE LAST SHOT OF
RAINFALL TO AREAS PRIMARILY NORTH OF CAPE MENDOCINO. RAISED POPS
TUESDAY NIGHT AS MODELS HAVE COME INTO BETTER ALIGNMENT FOR THIS
SYSTEM.

MODELS ARE NOW ALL INDICATING THAT A LARGE RIDGE WILL BUILD OVER THE
WEST COAST FOR LATE IN THE WEEK WITH A CONSIDERABLE WARMING TREND
EXPECTED. HIGH TEMPERATURES MAY APPROACH 90 FOR SOME INTERIOR VALLEY
LOCATIONS BY NEXT WEEKEND. RPA
