AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
354 AM PDT THU JUL 3 2014

.SYNOPSIS...AN UPPER LEVEL DISTURBANCE MOVING OVER NORTHWEST
CALIFORNIA WILL GENERATE ISOLATED TO SCATTERED DRY THUNDERSTORMS
THROUGH EARLY THIS EVENING. THE THUNDERSTORM THREAT WILL END BY
THURSDAY AS STABLE AIR MOVES OVER THE REGION. INLAND TEMPERATURES
WILL REMAIN AT OR ABOVE NORMAL INTO THE WEEKEND.

&&

.DISCUSSION...THE AIRMASS IS SLOWLY STABILIZING UNDER SOUTHWEST
FLOW. HEIGHTS WILL REMAIN FAIRLY CONSISTENT THROUGH FRIDAY THUS
TEMPERATURES WILL NOT VARY MUCH BOTH AT THE COAST AND INLAND. ON
SATURDAY HIGH PRESSURE WILL BEGIN TO BUILD BACK INTO THE AREA AND
BY SUNDAY AND MONDAY A NOTICEABLE RETURN TO VERY WARM AFTERNOONS
IS LIKELY FOR THE INTERIOR VALLEYS. BUMPED THE MONDAY TUESDAY
INTERIOR TEMPS UP 1-2 DEGREES BASED ON 32 DEGREE 850 TEMPS NUDGING
INTO TRINITY COUNTY. THE GFS AND ECMWF BOTH SHOW THE
RIDGE...ALTHOUGH THE ECMWF IS A BIT STRONGER. THE ONLY OTHER
CHANGE WAS ADDING POPS AND TSTORMS TO THE MONDAY AFTERNOON PERIOD
AND MAITAINING THE CURRENT POPS AND TSTORMS FOR TUES BASED ON GFS
SHOWING SOME OF THE MONSOONAL MOISTURE AND A WEAK UPPER FEATURE
MOVING NORTHWARD FROM OVER THE DESERT SOUTHWEST SLOWLY SHIFTING
NORTHWARD AND TO THE WEST. THIS WOULD BE A MORE FAVORABLE FLOW
PATTERN FOR CONVECTIVE ACTIVITY FOR NORTHWEST CA THAN WHAT WAS
OBSERVED THE LAST COUPLE OF DAYS.

&&

.AVIATION...MARINE STRATUS HAS SPREAD ALONG THE COAST NORTH OF THE
CAPE TO THE OREGON BORDER OVER NIGHT. IFR CIGS AT THE COASTAL AIR
FIELDS...KACV AND KCEC...WILL LIKELY HOLD IN THROUGH THE LATE
MORNING BEFORE BURNING OFF AROUND MIDDAY. EXPECT THE MARINE LAYER
STRATUS TO REFORM AROUND SUNSET AGAIN THIS EVENING AS FLOW CONTINUES
TO HAVE AN ONSHORE COMPONENT. OTHERWISE VFR CONDITIONS WILL BE THE
RULE INLAND AS RIDGING HAS SETTLE OVER THE AREA. MKN

&&

.MARINE...NORTHERLY WINDS HAVE PICKED UP AS EXPECTED THIS MORNING
OVER THE WATERS AS THE PRESSURE GRADIENT AGAIN TIGHTENS IN RESPONSE
TO BUILDING HIGH PRESSURE OVER THE REGION AND THE STRENGTHENING THERMAL
LOW OVER CALIFORNIA AS INLAND TEMPERATURES INCREASE. WINDS WILL
CONTINUE TODAY INTO TONIGHT PEAKING 20 TO 25 KT OVER THE SOUTHERN
WATERS. SEAS WILL BE MAINLY STEEP AND WIND DRIVEN REACHING AROUND 10
FEET OVER THE SOUTHERN WATERS THIS AFTERNOON. SEAS WILL PEAK AROUND
9 FEET OVER THE NORTHERN WATERS. WINDS AND SEAS WILL DIMINISH A BIT
FRIDAY INTO THE WEEKEND AS ANOTHER WEAK WAVE PASSES BY TO THE
NORTH...HOWEVER HIGH PRESSURE BUILDS BACK ON MONDAY AND TUESDAY WITH
NEAR GALE WINDS POSSIBLE. MKN

&&
