AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
302 PM PDT THU SEP 18 2014

.SYNOPSIS...SHOWERS WILL DISSIPATE THIS EVENING AS HIGH PRESSURE
BUILDS TOWARDS THE WEST COAST. THE HIGH WILL BRING WARMER
TEMPERATURES AND DRIER CONDITIONS TO NORTHWEST CALIFORNIA FRIDAY
THROUGH THE WEEKEND.

&&

.DISCUSSION...2145Z SATELLITE IMAGERY SHOWS AN UPPER LEVEL TROUGH
OVER NORTHERN CALIFORNIA, MOVING INLAND. 2145Z RADAR IMAGERY SHOWS
REMNANT SHOWERS ACROSS PORTIONS OF NORTHERN CALIFORNIA. THERE
REMAINS SOME INSTABILITY ACROSS THE AREA, SO A STRAY THUNDERSTORM
IS POSSIBLE FOR THE NEXT FEW HOURS. HOWEVER, CONFIDENCE IN THIS IS
LOW, SO REMOVED ANY MENTION OF THUNDERSTORMS FROM THE EVENING
FORECAST. OTHERWISE, SHOWERS WILL DISSIPATE THIS EVENING AS THE
UPPER LEVEL TROUGH MOVES INLAND AND IS REPLACED BY AN APPROACHING
RIDGE OF HIGH PRESSURE. AS THE TROUGH MOVES INLAND ON FRIDAY A CUT
OFF LOW WILL DEVELOP TO OUR SOUTH, OFF OF THE COAST OF SOUTHERN
CALIFORNIA. THIS LOW WILL REMAIN IN PLACE FRIDAY AND SATURDAY AS
RIDGING BUILDS OVER THE WEST COAST. NO RAIN OR THUNDERSTORMS ARE
EXPECTED FROM THIS LOW AS THE RIDGE WILL DOMINATE THE WEATHER
PATTERN. EXPECT DRY CONDITIONS AND NORMAL TO SLIGHTLY ABOVE NORMAL
TEMPERATURES THIS WEEKEND. MODELS SHOW THE LOW MOVING TO THE EAST
AND BEING ABSORBED INTO THE RIDGE ON SUNDAY. A LONG WAVE TROUGH
BEGINS TO MOVE OVER THE WEST COAST MONDAY THROUGH THE MIDDLE OF
NEXT WEEK. WITH THE MODELS IN GOOD AGREEMENT AND THE POTENTIAL FOR
ANOTHER FRONT AND RAIN FOR THE MIDDLE OF NEXT WEEK, BUMPED UP POPS
FOR THAT TIME PERIOD.

&&

.AVIATION...VFR CONDITIONS AND LIGHT WINDS WILL CONTINUE AT KCEC
AND KACV THROUGH THIS EVENING. PATCHY FOG MAY DEVELOP ACROSS SOME
AREAS EARLY FRIDAY MORNING REDUCING CEILINGS AND VISIBILITIES TO
MVFR CONDITIONS. VFR CONDITIONS AND LIGHT WINDS WILL PREVAIL AT
KUKI THROUGH FRIDAY.

&&

.MARINE...SEAS WILL CONTINUE TO SUBSIDE TONIGHT. A HIGH PRESSURE
SYSTEM WILL STRENGTHEN OFFSHORE FRIDAY INCREASING THE WINDS AND
SEAS PRIMARILY ACROSS THE OUTER WATERS. WINDS AND SEAS WILL
SUBSIDE SUNDAY AND MONDAY AS A LOW PRESSURE TROUGH MOVES ACROSS
THE REGION.
