AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
922 AM PDT MON APR 15 2013

.UPDATE...
UPDATED TO REMOVE MENTION OF FROST THIS MORNING AND ADJUST SKY
COVER/WX/POPS TO REFLECT LATEST TRENDS. SHOWER ACTIVITY HAS BEEN
RESTRICTED TO COASTAL AREAS BUT AS INSTABILITY OVER LAND INCREASES
THIS AFTERNOON EXPECT THE FOCUS TO SHIFT THERE. 500 MB
TEMPERATURES ARE ACTUALLY GOING TO BE -25C TO -30C ACROSS THE
NORTHERN HALF OF THE CWA THIS AFTERNOON AND HAVE ALREADY HAD ONE
REPORT OF SMALL HAIL IN CUTTEN. LOWER LEVEL TEMPERATURES ARE
MARGINAL AND SUSPECT ANYTHING THAT DOES REACH THE GROUND WILL BE
MIXED WITH RAIN AND NOT A THREAT TO TRAVEL. SNOW LEVELS ARE
ESTIMATED AROUND 2500 FEET BASED ON TEMP OBS BUT SO FAR HAVE NOT
BEEN ABLE TO OBTAIN GROUND TRUTH REPORTS. WEB CAM AT BERRY SUMMIT
IS SHOWING JUST WET CONDITIONS. WOULD NOT BE SURPRISED TO SEE SOME
MINOR ACCUMULATIONS ON GRASSY SFCS APPROACHING 3000 FEET BUT NO
SIGNIFICANT IMPACTS TO MAJOR PASSES EXPECTED. WILL HIGHLIGHT WITH
SOCIAL MEDIA. AAD

.PREV DISCUSSION... /ISSUED 346 AM PDT MON APR 15 2013/

SYNOPSIS...
ONLY ISOLATED SHOWERS WILL BE POSSIBLE NORTH OF CAPE MENDOCINO
OVER THE NEXT DAY OR SO WHILE AN UPPER LEVEL DISTURBANCE MOVES
THROUGH. THE NEXT FEW MORNINGS WILL BE FROSTY ESPECIALLY ACROSS THE
INTERIOR. WARMER AND DRIER WEATHER LATER IN THE WEEK AS HIGH PRESSURE
RE-ESTABLISHES ITSELF ACROSS THE REGION.

DISCUSSION...DRY AND CRISP NORTHERLY FLOW CONTINUES ACROSS THE
CWA THIS MORNING. MORNING LOW TEMPERATURES ACROSS INTERIOR OFF TO
A SLOW START BUT SHOULD FALL TO FROST ADVISORY CRITERIA BY SUNRISE.
OTHERWISE THE QUIET WEATHER PATTERN CONTINUES TO SLOWLY EVOLVE AS
MAIN TROUGH WHICH IS CURRENTLY BRINGING COOL TEMPERATURES TO THE
REGION VERY GRADUALLY SLIDES EASTWARD AND ALLOWS HIGHER HEIGHTS AND
THICKNESS VALUES TO EMERG BY LATE IN THE WEEK.  ONLY VERY LIMITED
SHOWER ACTIVITY EXPECTED OVER THE COASTAL WATERS AND OVER THE
NORTHERN INTERIOR MOUNTAINS TODAY.  OTHERWISE MOST OTHER AREAS SHOULD
STAY DRY. REMAINDER OF THIS WEEK INTO NEXT WEEKEND CONTINUES TO LOOK
DRY. TOMORROW NIGHT/TUESDAY MORNING WILL BE THE BEST CHC OF FREEZING
TEMPERATURES INLAND WITH EVEN SOME FROST POSSIBLE NEAR THE COAST
WHERE ATMOSPHERE DECOUPLES AND SFC WINDS CALM. EVEN WEDNESDAY
MORNING LOOKS CHILLY...BUT TEMPERATURES SHOULD BEGIN TO WARM AS
RIDGE BUILDS FOR THE REST OF THIS WEEK. DRY AND WELL-MIXED AIRMASS
SHOULD PRECLUDE MUCH STRATUS OR FOG FORMATION AT THE COAST BUT THIS
WILL BEGIN TO BECOME A CHALLENGE LATE IN THE WEEK AND NEXT WEEKEND.
LOW LEVEL WINDS WILL HAVE A VERY SLIGHT NORTHEAST COMPONENT OVERNIGHT
SO HOW MUCH COASTAL STRATUS AND HOW LONG IT LASTS THROUGH THE DAY IS
VERY QUESTIONABLE. AAD/JT

AVIATION...GUSTY NW WINDS DEVELOPING TODAY AND THIS EVENING. CIGS
AND VSBYS REMAINING VFR WITH PERHAPS BRIEF ISOLATED FLUCTUATIONS TO
MVFR IN A SHOWER OR TWO.

MARINE...STRONG AND GUSTY NORTHERLY WINDS WILL DEVELOP TODAY AS A
COLD AIR MASS SURGES SOUTHWARD. WIND GUSTS SHOULD APPROACH 35-40KT,
MOST FREQUENT AND WIDESPREAD SOUTH OF THE CAPE. NORTH WINDS LOOK TO
BE STRONGER WITHIN 20NM PER THE LOCAL RUN OF THE WRF MODEL. THUS MADE
SOME MINOR ADJUSTMENTS TO GLW AND SCA HEADLINES THROUGH TONIGHT.
STRONG HIGH PRESSURE WILL REMAIN ANCHORED WEST OF THE REGION THROUGH
MIDWEEK MAINTAINING MODERATE TO OCCASIONALLY STRONG NORTHERLIES AND
STEEP SHORT PERIOD SEAS. WINDS SHOULD EASE UP AND SEAS SUBSIDE
TOWARD END OF THE WEEK...BUT CURRENT INDICATIONS ARE FOR MODERATE
NORTH WINDS TO RAMP UP AGAIN THIS WEEKEND.
