409 PM PST MON MAR 5 2012

.SYNOPSIS...
A BRIEF PERIOD OF RAIN THIS EVENING WILL TAPER TO SHOWERS WHICH WILL
LINGER INTO TUESDAY. DRY WEATHER AND SUNSHINE WILL RETURN FOR THE
REST OF THE WEEK. THE NEXT CHANCE OF RAIN WILL ARRIVE FOR THE
WEEKEND.

.SHORT TERM...A COLD FRONT WILL MARCH THROUGH NW CALIFORNIA THIS
EVENING. VIS SAT THIS AFTERNOON SHOWS A WELL DEFINED FRONT THAT HAS
ALREADY MOVED THROUGH MUCH OF COASTAL OREGON. RAIN IS EXPECTED TO
BEGIN IN CRESCENT CITY AND DEL NORTE COUNTY AFTER 3PM. RAIN WILL
SPREAD SOUTH OVERNIGHT, BRINGING PRECIP TO MENDOCINO COUNTY AROUND
MIDNIGHT. RAIN WILL TURN TO SHOWERS BEHIND THE FRONT AND COLD AIR
WILL MIGRATE INTO NW CALIFORNIA. SNOW LEVELS WILL FALL TO 1000 TO
2000 FT AT THIS TIME. HOWEVER, THERE WILL NOT BE HIGH AMOUNTS OF
MOISTURE BEHIND THE FRONT FOR SIGNIFICANT SNOW FALL. ACCUMULATIONS
WILL GENERALLY BE UNDER A FEW INCHES. THE MORE IMMEDIATE THREAT WILL
BE COLD AIR CONVECTION IN THE COASTAL INFLUENCED AREAS. THIS WILL
BRING THE THREAT OF SOME SMALL HAIL LATE TONIGHT INTO TUESDAY. A
WEAK DISTURBANCE MAY TRY TO KICK OFF SOME SHOWERS TUESDAY AFTERNOON
AROUND DEL NORTE COUNTY BUT WITH RISING HEIGHTS AND SUBSIDENCE ALOFT
ANY SHOWERS WILL HAVE A TOUGH TIME DEVELOPING. HIGH PRESSURE WILL
SQUEEZE UP AGAINST THE AREA BY TUE BRINGING STRONG WINDS TO THE
COASTAL AREAS AND ALONG THE RIDGETOPS. SKIES WILL BEGIN TO CLEAR AND
WINDS WILL CALM BY WED. LOOK FOR TEMPS TO REMAIN COOL AS THIS COLD
AIR POOL SLIDES IN BEHIND THE FRONT. BFG

.LONG TERM...
HIGH PRESSURE RIDGE WILL EVENTUALLY GIVE WAY TO A DEEPENING LONG
WAVE TROUGH AND AN INCREASINGLY WET PATTERN HEADING TOWARD NEXT
WEEK. THE NEXT FRONT HAS BEEN ADVERTISED BY BOTH THE EURO AND THE
GFS TO ARRIVE SOME TIME IN THE VICINITY OF FRIDAY NIGHT OR SATURDAY.
THERE WILL LIKELY BE A LULL THEREAFTER BUT WITH UNCERTAINTY IN
TIMING WE KEPT CHC POPS UNTIL THE NEXT SYSTEM IS PROGGED TO ARRIVE
AROUND SUNDAY NIGHT OR MONDAY. GIVEN THE LONGWAVE PATTERN BEING
ADVERTISED BY THE MODELS WE MAY ACTUALLY SEE SOME SERIOUS RAIN NEXT
WEEK. AAD
