AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
244 PM PDT SAT OCT 4 2014
.SYNOPSIS...DRY AND WARM CONDITIONS WILL PERSIST FOR THE NEXT
SEVERAL DAYS AS A STRONG RIDGE OF HIGH PRESSURE REMAINS OVER THE
REGION.
&&
.DISCUSSION...WITH THE WEAKENING OFFSHORE PRESSURE GRADIENT THE
SEA BREEZE KICKED IN EARLIER AND TEMPERATUES AT THE COAST WERE 5
TO 10 DEGRESS COOLER THAN FRIDAY WHILE INLAND TEMPS WERE ABOUT THE
SAME OR SLIGHTLY WARMER. THE TREND IS FOR A SLIGHTLY STRONGER
ONSHORE FLOW AT THE COAST AS THE THERMAL TROUGH STRENGTHENS SO
SOME COOLING. THE ONLY CHANGE FOR SUNDAY IS TO REDUCE THE AMOUNT
OF STRATUS THAT DEVELOPS. MODELS SHOWING HUMIDITIES STILL FAIRLY
DRY IN THE LOWER LEVELS IN THE ATMOSPHERE THOUGH THERE IS A SLIGHT
INCREASE AT THE SURFACE SO EXPECT SOME PATCHY FOG NEAR THE OCEAN
AND SOME COASTAL VALLEYS BUT OTHERWISE CLEAR.
OVERALL TREND INTO THE MIDDLE OF THE WEEK IS THE SAME WITH THE RIDGE
FLATTENING AS ENERGY IN ALASKA MOVES INTO THE NORTHERN ROCKIES
AND THE DEEP TROUGH IN THE EASTERN U.S. STARTS TO LIFT OUT.
MODELS SHOULD A VERY WEAK FRONT DROPPING DOWN THE PAC NW COAST AND
THEN DISSIPATING JUST NORTH OF THE OREGON BORDER TUE AND WED. THE
ONLY IMPACT FROM ALL OF THIS IS GRADUAL COOLING INLAND AND
INCREASING CLOUDS AT THE COAST.
MODELS STILL DIFFERING IN THE EXTENDED. GFS HAS STRONG RIDGE
BUILDING BACK AND DEVELOPING JUST OFF THE COAST NEXT WEEKEND WITH
THE DRY WEATHER CONTINUING AND TEMPS AGAIN INCREASING. THE EC MODELS
SOLUTIONS HAVE BEEN VARYING BUT BASICALLY BUILD RIDGE FURTHER WEST
TAKING MORE ENERGY IN THE NORTHERN JET AND DRIVING IT INTO GREAT
BASIN. WHILE THIS PATTERN IS GENERALLY DRY, THE COOLING TREND WOULD
ACCELERATE. BY SAT AFTERNON, THE DIFFERENCES IN THE MODELS RESULT IN
TEMPS AT ABOUT 5000 FEET (850MB) VARYING FROM 24 C WITH GFS AND ONLY
6 TO 12 C WITH THE EC. WENT WITH GFS PER WPC THOUGH THE GFS MODEL
TRENDS HAVE BEEN TO HAVE THE RIDGE DEVELOPING A LITTLE FURTHER
WEST. INTRODUCED VERY LOW POPS IN FOR NEXT WEEKEND IN THE FAR
NORTH TO MATCH UP WITH MEDFORD. DEAN
&&
.AVIATION...VFR CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL
CONTINUE THROUGH SUNDAY AS A HIGH PRESSURE RIDGE PERSIST ACROSS THE
REGION. DEW POINTS ARE INCREASING SLIGHTLY AND SHOULD SEE SOME
PATCHY FOG AROUND HUMBOLDT BAY NEAR SUNRISE AND NEAR THE OCEAN.
DEAN
&&
.MARINE...THE WEATHER PATTERN WILL BE DOMINATED BY A RIDGE OF HIGH
PRESSURE OVER OR NEAR THE WEST COAST FOR THE NEXT WEEK.
HOWEVER...SLIGHT DIFFERENCES IN THE MODELS REGARDING THE LOCATION OF
THE RIDGE AXIS WILL HAVE MAJOR IMPLICATIONS ON THE FORECAST IN THE
LONG RANGE.
AS FOR THE NEXT FEW DAYS...A STRONG THERMAL TROUGH WILL REMAIN IN
PLACE OVER THE INTERIOR STRETCHING NORTH TOWARD THE OREGON BORDER.
THIS WILL ALLOW THE TIGHTEST PRESSURE GRADIENT TO REMAIN JUST NORTH
OF THE WATERS. HOWEVER STEEP SHORT PERIOD SEAS ARE FORECAST TO
PROPAGATE INTO THE NORTHERN OUTER WATER ZONE SO A SMALL CRAFT
ADVISORY HAS BEEN ISSUED WITH THIS UPDATE FOR TOMORROW AFTERNOON
THROUGH MONDAY MORNING.
ON TUESDAY A DRY...WEAK FRONT WILL SLIDE DOWN THE WEST COAST
TIGHTENING THE PRESSURE GRADIENT IN ITS WAKE AND INCREASING THE
NORTHERLY WINDS SLIGHTLY. THIS WILL POSSIBLY REQUIRE SOME SMALL
CRAFT ADVISORIES AROUND MID WEEK BUT CONFIDENCE IN THE MAGNITUDE OF
THESE WINDS IS LOW. LATE IN THE WEEK THE MAJOR MODEL DIFFERENCES
WILL COME INTO PLAY WITH NORTHERLIES INCREASING FOR NEXT WEEKEND IF
THE DEEPER INTER-MOUNTAIN U.S. ECMWF MODEL TROUGH IS CORRECT VS THE
GFS FARTHER EAST TROUGH RESULTING IN HIGH AMPLITUDE RIDGING DIRECTLY
OVER THE WEST COAST AND THUS LIGHTER WINDS. RPA
