AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
303 PM PDT FRI MAY 17 2013

.SYNOPSIS...A WEAK DISTURBANCE WILL BRING A SLIGHT CHANCE OF
SHOWERS TO AREAS NORTH OF CAPE MENDOCINO ON SATURDAY.
OTHERWISE...EXPECT A WARMING AND DRYING TREND THROUGH THE
WEEKEND.

&&

.DISCUSSION...NO MAJOR CHANGES MADE TO THE FORECAST. SATELLITE
SHOWS SOME CLOUDS ALONG THE REDWOOD COAST WHILE RADAR SHOWS NO
PRECIPITATION. REMNANT LOW LEVEL MOISTURE ACROSS THE CWA TONIGHT
SHOULD ALLOW FOG TO FORM ALONG THE COAST AND IN THE VALLEYS. THIS
SHOULD QUICKLY BURN OFF ON SATURDAY. A DRYING AND WARMING TREND
WILL PERSIST THROUGH THE WEEKEND AS A WEAK RIDGE BUILDS ALONG THE
WEST COAST. A WEAK DISTURBANCE WILL PASS MOSTLY TO OUR NORTH ON
SATURDAY, BRINGING A SLIGHT CHANGE OF SHOWERS TO AREAS NORTH OF
CAPE MENDOCINO. MODELS ARE IN GREAT AGREEMENT SAYING QPF WILL BE
LITTLE, IF ANYTHING. THIS ESPECIALLY ALONG THE CA/OR BORDER, WHICH
IS REFLECTED IN LOW POPS. CONDITIONS WILL BE DRY SUNDAY AND
MONDAY. THE RIDGE STARTS TO BREAK DOWN EARLY NEXT WEEK AND IS
REPLACED BY A TROUGH BUILDING IN FROM THE PACIFIC NORTHWEST. THE
MAIN ENERGY WITH THIS SHOULD STAY TO OUR NORTH DURING THE MIDDLE
OF NEXT WEEK, BUT INSTABILITY SHOWERS ARE POSSIBLE. KEPT POPS
AROUND CLIMO FROM TUESDAY ONWARD TO REFLECT THIS. THE SYSTEM
DOESN`T APPEAR TO TAP INTO PACIFIC MOISTURE, WHICH IS GOOD AND NO
THUNDERSTORMS ARE FORECAST AT THIS TIME.

&&

.AVIATION...VFR CONDITIONS AND LIGHT TO MODERATE WINDS WILL
CONTINUE AT KCEC, KACV AND KUKI THROUGH THE EARLY EVENING. PATCHY
FOG WILL DEVELOP ALONG SOME COASTAL AREAS OVERNIGHT REDUCING
VISIBILITIES TO MVFR CONDITIONS AT KCEC AND KACV WITH LIGHT WINDS.
LIGHT WINDS AND VFR CONDITIONS WILL PREVAIL AT KUKI THROUGH
SATURDAY.

&&

.MARINE...LIGHT TO MODERATE WINDS AND MODERATE SEAS WILL PREVAIL
ACROSS THE WATERS THROUGH SATURDAY MORNING. A STRENGTHENING HIGH
PRESSURE SYSTEM LOCATED OVER THE NORTHEAST PACIFIC WILL INTERACT
WITH A DEVELOPING COASTAL LOW PRESSURE TROUGH LOCATED ACROSS
CALIFORNIA THIS WEEKEND TIGHTENING THE PRESSURE GRADIENT. THE
WINDS AND SEAS WILL INCREASE ACROSS THE WATERS THIS WEEKEND AND
EARLY NEXT WEEK. SMALL CRAFT ADVISORIES WILL BE NECESSARY ACROSS
THE NEARSHORE WATERS EARLY SUNDAY MORNING THROUGH TUESDAY MORNING.
GALE WARNINGS WILL BE NECESSARY ACROSS THE OUTER WATERS EARLY
SUNDAY THROUGH TUESDAY MORNING. THE SMALL CRAFT ADVISORIES AND
POSSIBLY GALE WARNINGS WILL LIKELY BE EXTENDED BEYOND TUESDAY.

&&
