AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
307 PM PDT TUE SEP 8 2015

.SYNOPSIS...HIGH PRESSURE OVERHEAD WILL PROLONG DRY WEATHER AND ABOVE
NORMAL TEMPERATURES FOR INTERIOR LOCATIONS THROUGH THE WORK WEEK.
TEMPERATURES WILL REMAIN MORE SEASONAL ALONG THE COAST WITH PATCHES
OF FLEETING CLOUDS EACH EVENING. THE RIDGE WILL BEGIN TO BREAK
DOWN ON FRIDAY BRINING SEASONAL TEMPERATURES BACK TO NORTHERN
CALIFORNIA OVER THE WEEKEND.

&&

.SHORT TERM (TODAY THROUGH FRIDAY)...A RIDGE OF HIGH PRESSURE WILL
DOMINATE THE WEATHER PATTERN BRINGING DRY CONDITIONS AND WARM, ABOVE
NORMAL TEMPERATURES TO INTERIOR LOCATIONS THROUGH THE WORK WEEK.
COASTAL TEMPERATURES WILL REMAIN MORE SEASONAL TO POSSIBLY A FEW
DEGREES ABOVE NORMAL. MODERATE TO WEAK OFFSHORE FLOW WILL PERSIST
OVER THE NEXT FEW EVENINGS HELPING TO INHIBIT MUCH CLOUD DEVELOPMENT
ALONG THE NORTH COAST. HOWEVER, SOME PATCHES OF FLEETING CLOUDS
COULD DEVELOP AROUND THE HUMBOLDT BAY AREA EACH NIGHT WITH CLEARING
BY THE LATE MORNING HOURS. NORTHERN CALIFORNIA WILL OTHERWISE REMAIN
MOSTLY CLEAR THROUGH THE WORK WEEK.

BY FRIDAY, 500 MB HEIGHT WILL FALL AS THE UPPER RIDGE BEGINS TO
BREAK DOWN. THIS WILL MARK THE BEGINNING OF A PATTERN CHANGE LEADING
INTO THE WEEKEND. KML

.LONG TERM (SATURDAY THROUGH TUESDAY)...MODELS INDICATE AN INCREASE
IN THE ATMOSPHERIC MOISTURE ACROSS THE REGION THIS WEEKEND. HOWEVER
THE INCREASE DEPENDS ON THE TRACK OF THE MOISTURE ASSOCIATED WITH
THE REMNANTS OF HURRICANE LINDA, CURRENTLY WEST OF MEXICO, ONCE THE
STORM DISSIPATES. ALSO MODELS SHOW A LOW PRESSURE TROUGH MOVING JUST
NORTH OF THE REGION SUNDAY INCREASING THE ATMOSPHERIC MOISTURE
ACROSS THE AREA. HOWEVER THE CURRENT FORECAST REMAINS DRY THIS
WEEKEND DUE TO UNCERTAINTIES OF THESE SYSTEMS IN THE MODELS.

&&

.AVIATION...VFR CONDITIONS AND LIGHT TO MODERATE WINDS WILL CONTINUE
AT KCEC AND KACV THROUGH THE EARLY EVENING. VFR TO MVFR CONDITIONS
AND LIGHT WINDS TO CALM CONDITIONS WILL OCCUR AT KCEC AND KACV
OVERNIGHT WITH THE LOWER CONDITIONS DUE TO STRATUS AND/OR PATCHY FOG
REDUCING CEILINGS AND/OR VISIBILITIES. VFR CONDITIONS AND LIGHT TO
MODERATE WINDS WILL PREVAIL AT KCEC AND KACV WEDNESDAY. VFR
CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL CONTINUE AT KUKI
THROUGH WEDNESDAY.

&&

.MARINE...MODERATE TO STRONG WINDS AND SHORT PERIOD SEAS
CONTINUED ACROSS THE OUTER WATERS TODAY AS AN OFFSHORE HIGH PRESSURE
SYSTEM INTERACTED WITH AN INLAND THERMAL LOW PRESSURE TROUGH
MAINTAINING A TIGHT PRESSURE GRADIENT. THE OFFSHORE HIGH PRESSURE
SYSTEM WILL WEAKEN THE NEXT FEW DAYS AND THE INLAND THERMAL LOW
PRESSURE TROUGH WILL PROPAGATE FURTHER INLAND RELAXING THE PRESSURE
GRADIENT ACROSS THE WATERS. THEREFORE NORTHERLY WINDS AND STEEP
SHORT PERIOD SEAS WILL DECREASE THE NEXT FEW DAYS. SMALL CRAFT
ADVISORIES WILL CONTINUE ACROSS THE SOUTHERN OUTER WATERS THROUGH
WEDNESDAY NIGHT. A HAZARDOUS SEAS WARNING WILL CONTINUE ACROSS THE
SOUTHERN OUTER WATERS THROUGH THIS EVENING. A GALE WARNING WILL
CONTINUE ACROSS THE NORTHERN OUTER WATERS THROUGH EARLY WEDNESDAY
MORNING.

&&

.FIRE WEATHER...WEAK TO MODERATE OFFSHORE FLOW WILL PERSIST OVER THE
NEXT FEW EVENINGS AS THE THERMAL TROUGH REMAINS STATIONED OVER
COASTAL CALIFORNIA. OVERNIGHT WIND GUSTS SHOULD HAVE THE GREATEST
IMPACT ON THE MID TO UPPER SLOPES ESPECIALLY OVER DEL NORTE AND
NORTHERN HUMBOLDT COUNTY WHERE THE OFFSHORE FLOW WILL BE MOST
PROMINENT. GUSTS AROUND 15 TO 20 MPH WILL NOT BE OUT OF THE QUESTION
FOR THESE AREAS WHILE THE REST OF HUMBOLDT, TRINITY, AND MENDOCINO
COUNTIES CAN SEE RIDGETOP GUSTS IN THE NEIGHBORHOOD OF 15 MPH. WE
CONTINUED TO HEADLINE THESE WINDS IN THE FIRE WEATHER FORECAST.

BROAD UPPER LEVEL RIDGING WILL OTHERWISE MAINTAIN DRY WEATHER AND
ABOVE NORMAL TEMPERATURES THROUGH THE WORK WEEK. RH RECOVERIES WILL
BE MODERATE OVER THE NEXT FEW NIGHTS WHILE THE MID SLOPES SHOULD
EXPERIENCE POOR RECOVERIES DUE TO THE DRY, EASTERLY FLOW. THE
PATTERN WILL BEGIN TO CHANGE OVER THE WEEKEND AS THE UPPER RIDGE
BREAKS DOWN AND ALLOWS DAYTIME TEMPERATURES TO FALL TO NEAR
NORMAL AND RH RECOVERIES TO IMPROVE. MODELS CONTINUE TO STRUGGLE
WITH THE TRACK OF WHAT IS EXPECTED TO BE REMNANTS OF TROPICAL
STORM LINDA OVER THE WEEKEND AND INTO EARLY NEXT WEEK. THIS IS
SOMETHING WE WILL NEED TO WATCH AS A PULSE OF MOISTURE FROM THE
STORM COULD MOVE INTO NW CAL, BRINGING A CHANCE OF THUNDERSTORMS.
FOR NOW AM KEEPING ANY MENTION OUT OF THE FORECAST DUE TO
EXTREMELY LOW CONFIDENCE. KML

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
