AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
407 AM PDT TUE NOV 2 2010

.SYNOPSIS...A WEAK RIDGE WILL REMAIN OVER THE AREA TODAY ALLOWING
FOR ANOTHER DAY OF FAIR WEATHER. THE NEXT ROUND RAIN WILL BEGIN
LATE THIS WEEK.

&&

.DISCUSSION...A RIDGE WILL CONTINUE TO DOMINATE THE REGION TODAY
WHILE A FRONT STRETCHED ACROSS OREGON STALLS AND DISSIPATES.
MODELS CONTINUE TO CONVERGE ON THE SOLUTION OF AN UPPER TROUGH AND
SURFACE FRONT FOR THE REGION ON FRIDAY. WITH LESS AGREEMENT
BETWEEN THE MODELS, ANOTHER FRONT WILL FOLLOW LATE IN THE WEEKEND.

SHORT TERM...AS A RESULT THE PATTERN WILL BEGIN TO SHIFT ALONG
THE COAST BEGINNING TODAY AS A BRANCH OF THE SURFACE HIGH MOVES TO
THE EAST AND HIGH PRESSURE OFF OF SW CAL MOVES NORTHWARD. THIS
WILL CAUSE THE WINDS TO BECOME NORTHERLY TODAY ALONG THE COAST AND
LIMIT THE TEMPERATURES NEAR THE WATER. WHERE MONDAY SAW RECORD OR
NEAR RECORD HIGHS, TUESDAY WILL SQUEAK IN A FEW DEGREES ABOVE
NORMAL BUT NOT NEAR RECORD TERRITORY. INLAND TEMPS ON THE OTHER
HAND WILL NOT HAVE QUITE THE INFLUENCE FROM THE NORTHERLY WIND
REGIME AS THE COAST. THIS WILL ALLOW FOR A FAIR BIT OF WARMING
ACROSS THE INTERIOR TODAY, WITH HIGHS IN THE MID TO UPPER 70'S.
ALONG WITH OVERNIGHT COASTAL AND VALLEY FOG, THIS PATTERN SHOULD
LAST INTO THU.

LONG TERM...FRIDAY WILL BRING SIGNIFICANT CHANGE TO THE WEATHER
AS A SHARP UPPER TROUGH AND SURFACE FRONT SWEEP THROUGH THE AREA.
WHILE TIMING VARIES IN THE MODELS, IT LOOKS LIKE THE SURFACE FRONT
WILL BE PASSING THROUGH THE AREA LATE IN THE AFTERNOON INTO THE
EARLY EVENING. RAIN WILL BEGIN EARLIER IN THE DAY ALONG THE COAST
THEN SPREAD INLAND OVER THE COURSE OF THE DAY. POPS REMAIN
SOMEWHAT LOW TO ACCOUNT FOR THE TIMING DISCREPANCIES, BUT AS MODEL
GET A BETTER HANDLE ON THE TIMING POPS WILL INCREASE. THIS WILL
LIKELY BE A HIGH POP LOW QPF EVENT. BEHIND THIS FRONT, A BRIEF
BREAK IS EXPECTED BEFORE THE NEXT FRONT LATE IN THE WEEKEND. BFG

.AVIATION...SATELLITE FOG PRODUCT SHOWS LOW CLOUD OVER COASTAL AREAS
THIS MORNING...EXTENDING INLAND THROUGH COASTAL VALLEYS INCLUDING
THE EEL RIVER VALLEY...INLAND MENDOCINO...AND THE KLAMATH AND
TRINITY RIVER BASINS. EXPECT THE LAYER TO SCATTER OUT BY AROUND NOON
TODAY AS HIGH PRESSURE BRINGS WIDESPREAD SUBSIDENCE AND LIGHT
OFFSHORE FLOW TO THE AREA. CILIBERTI
