AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
452 AM PDT MON APR 25 2016

.UPDATED AVIATION DISCUSSION.

.DISCUSSION...THE CLOSED LOW PRESSURE HAS MOVED INTO NORTHERN
CALIFORNIA THIS MORNING. THE LOW IS EXPECTED TO CONTINUE TO MOVE
SOUTHEAST INTO NEVADA. ISOLATED SHOWERS CONTINUE FROM THE CASCADES
WEST. SNOW SHOWERS WILL CONTINUE OVER THE WARNERS THIS MORNING
FROM MOISTURE WRAPPED AROUND THE LOW BUT BY THIS AFTERNOON THE
ATMOSPHERE IS EXPECTED TO STABILIZE UNDER NW FLOW ALOFT.

WE ARE EXPECTING LESS CLOUD COVER TONIGHT THAN PREVIOUSLY THOUGHT
AND THE RADIATIONAL COOLING COULD BRING OVERNIGHT LOWS FOR SW
OREGON AND NORTHERN CALIFORNIA VALLEYS INTO THE LOWER TO MID 30S
AND FROST IS POSSIBLE OVERNIGHT. PLEASE TAKE NEEDED PRECAUTIONS TO
AVOID FROST DAMAGE.

NO PRECIPITATION IS IN THE FORECAST FOR INLAND AREAS TUESDAY AS A
RIDGE BUILDS INTO THE AREA.THE ONLY EXCEPTION IS IN OUR MARINE
ZONES WHERE THE NEXT FRONT COULD SPREAD LIGHT RAIN LATE IN THE
DAY. THE WARM FRONT IS EXPECTED TO SPREAD LIGHT RAIN INLAND
TUESDAY NIGHT. THE UPPER LEVEL SUPPORT FOR THIS NEXT SYSTEM DIVES
INTO NORTHERN CALIFORNIA AGAIN ON WEDNESDAY BUT THERE WILL STILL
BE ENOUGH MOISTURE AND INSTABILITY TO PRODUCE SHOWERS IN SOUTHERN
OREGON.

SHOWERS WILL LINGER ACROSS THE WARNER MOUNTAINS ON THURSDAY BUT
THE REST OF OUR FORECAST AREA IS EXPECTED TO BE DRY. /FB

&&

.AVIATION...FOR THE 25/12Z TAF CYCLE...PLENTY OF LOW LEVEL MOISTURE
REMAINS THIS MORNING AND THIS HAS RESULTED IN IFR CIGS/VIS THAT
DEVELOPED WITHIN THE LAST COUPLE OF HOURS AT ROSEBURG. EXPECT THESE
CONDITIONS TO LAST FOR MOST OF THE MORNING, ALTHOUGH THERE IS A
CHANCE CIGS COULD IMPROVE TO MVFR AROUND 18Z. ELSEWHERE EXPECT VFR
CIGS TO BE THE PREDOMINATE CONDITION, BUT MOUNTAINS ARE EXPECTED TO
BE AT LEAST PARTLY OBSCURED THIS MORNING. ALSO CIGS COULD SEE SAW
BRIEFLY FROM VFR TO MVFR AT KLAMATH FALLS THIS MORNING, BUT
CONFIDENCE IS LOW, SO KEPT IT OUT OF THE TAF. STABLE CONDITIONS WILL
CONTINUE TONIGHT WITH A CHANCE FOR IFR CIGS TO RETURN AT ROSEBURG.

.MARINE...UPDATED 300 AM PDT MON 25 APR 2016...MODELS CONTINUE TO
SHOW LOW END SMALL CRAFT FOR SEAS WITH A WEST DOMINATED SWELL
AFFECTING ALL THE THE MARINE WATERS THROUGH THIS EVENING. HIGH
PRESSURE WILL BUILD OFFSHORE TODAY AND NORTH WINDS ARE EXPECTED TO
INCREASE. THE RAP SHOWS SMALL CRAFT FOR WINDS EDGING CLOSER TOWARDS
THE COAST, SO HAVE ADJUSTED THE SMALL CRAFT FOR WINDS TO REFLECT
THIS THIS THINKING. HIGH PRESSURE WILL WEAKEN AND MOVE OVER THE
WATERS TONIGHT THROUGH TUESDAY. A WEAK FRONT WILL MOVE THROUGH THE
WATERS TUESDAY NIGHT...THEN OFFSHORE HIGH PRESSURE REBUILDS AGAIN
WEDNESDAY AFTERNOON. THE MODELS REMAIN IN FAIRLY GOOD AGREEMENT
SHOWING A THERMAL TROUGH DEVELOPING AND STRENGTHENING BY THE LATTER
PART OF THE WEEK. WINDS IN THE SOUTHERN WATERS COULD REACH HIGH END
SMALL CRAFT BY THURSDAY WITH GALES POSSIBLE OVER THE SOUTHERN
PORTIONS OF MARINE ZONES 356 AND 376. NOTE THAT DETAILS ON THIS
COULD CHANCE, SO WATCH FOR UPDATES ON THIS. -PETRUCELLI
