AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MEDFORD OR
218 PM PDT WED AUG 5 2015

.SHORT TERM...A ZONAL FLOW PATTERN IS OVER THE AREA TODAY WITH
SOME LINGERING MOISTURE AND INSTABILITY OVER EASTERN PORTIONS OF
THE AREA. THERE IS A SLIGHT CHANCE FOR SHOWERS OR THUNDERSTORMS IN
EASTERN SISKIYOU AND SOUTHEAST LAKE COUNTIES. MAINLY EXPECT JUST
SOME BUILDING CUMULUS CLOUDS OVER EASTERN AREA THOUGH. GOOD
MIXING TODAY ALONG WITH INCREASED WEST TO NORTHWEST FLOW IS
HELPING THIN SMOKE OVER MUCH OF THE AREA. ADDITIONAL SMOKE FROM
THE STOUT FIRE THOUGH IS EXPECTED TO BRING INCREASED AREAS OF
SMOKE IN THE ROGUE VALLEY AGAIN LATE THIS AFTERNOON AND THIS
EVENING.

TONIGHT INTO THURSDAY, A SURFACE THERMAL TROUGH WILL STRENGTHEN
ALONG THE COAST. THIS WILL BRING GUSTY NORTHEAST WINDS TO THE
COASTAL MOUNTAINS. ALSO EXPECT A MODERATE CHETCO WARMING EFFECT
FOR THE BROOKINGS AREA ON THURSDAY.

THE PATTERN BEGINS TO CHANGE ON THURSDAY WITH AN UPPER LOW OFF THE
COAST OF CENTRAL CALIFORNIA FORECAST TO MOVE INTO THE SAN
FRANCISCO BAY AREA THURSDAY EVENING THEN MOVING INLAND THURSDAY
NIGHT INTO FRIDAY. SOUTHERLY MOISTURE IS EXPECTED TO MOVE INTO
NORTHERN CALIFORNIA FRIDAY MORNING. THIS COMBINED WITH MID LEVEL
MOISTURE AND WEAK DISTURBANCES WILL BRING A SLIGHT CHANCE FOR
THUNDERSTORMS FRIDAY MORNING TO NORTHERN CALIFORNIA ZONES. AS THE
LOW SHIFTS NORTHEASTWARD INTO NORTHEAST CALIFORNIA AND NORTHWEST
NEVADA EXPECT MOISTURE TO ROTATE INTO THE AREA. THIS MOISTURE
COMBINED WITH INCREASED DAYTIME INSTABILITY AND  UPPER LEVEL
DISTURBANCES IS EXPECT TO BRING AN INCREASED RISK FOR
THUNDERSTORMS TO NORTHERN CALIFORNIA AND AREAS EAST OF THE
CASCADES. THE BEST CHANCE FOR THUNDERSTORMS IS OVER MODOC, LAKE,
SOUTHEAST KLAMATH AND EASTERN SISKIYOU COUNTIES. THE RISK FOR
THUNDERSTORMS CONTINUES INTO FRIDAY NIGHT THEN IS EXPECTED TO
DECREASE SATURDAY MORNING.

.LONG TERM...SATURDAY AND SUNDAY...EXPECT A SOUTHWEST FLOW PATTERN
TO DEVELOP ALOFT AS A PACIFIC UPPER LOW MOVES SOUTH DOWN THE
BRITISH COLUMBIA COAST WITH AN UPPER TROUGH DEVELOPING OFFSHORE
AND A RIDGE CENTERED INLAND EAST OF THE AREA. SOME WEAK
INSTABILITY AND MOISTURE MAY BRING A SLIGHT CHANCE OF
THUNDERSTORMS SATURDAY OVER NORTHERN CALIFORNIA AND FROM THE
CASCADES EAST IN OREGON. THE CHANCE FOR THUNDERSTORMS IS WEAKER
ON SUNDAY AND LIMITED TO AREAS FROM THE CASCADES EAST IN OREGON.
ALSO ON SUNDAY, AS THE UPPER TROUGH MOVES INTO THE PACNW COAST,
EXPECT A MARINE PUSH TO BRING AREAS OF LOW CLOUDS INTO THE COAST
AND UMPQUA VALLEY. SHOWERS ARE ALSO POSSIBLE IN THESE AREAS,
MAINLY SUNDAY NIGHT INTO MONDAY.

MONDAY THROUGH WEDNESDAY...THE UPPER TROUGH LINGERS ALONG THE
PACNW COAST WHILE THE MAIN UPPER LOW SHIFTS INTO CANADA. ALONG THE
SOUTHERN END OF THE TROUGH, AN UPPER LOW MAY DEVELOP OFF THE
NORTHERN CALIFORNIA COAST LATE TUESDAY AND INTO WEDNESDAY. THIS
PATTERN WILL BRING A SLIGHT CHANCE OF THUNDERSTORMS TO CENTRAL
PORTIONS OF THE AREA MONDAY AND TUESDAY, MAINLY NEAR THE CASCADES.
THEN ON WEDNESDAY, MAY SEE INCREASED CHANCES FOR THUNDERSTORMS
OVER INLAND AREAS WITH THE UPPER LOW OFFSHORE PUSHING INLAND
DURING THE DAY. MODELS SHOW CONSIDERABLE VARIABILITY FOR THE TRACK
AND STRENGTH OF THIS UPPER LOW ON TUESDAY AND WEDNESDAY. GIVEN
THIS VARIABILITY HAVE ADDED A BROAD AREA OF SLIGHT CHANCE FOR
THUNDERSTORMS, WHICH COVERS MUCH OF THE INLAND AREA, TO THE
WEDNESDAY FORECAST.

&&

.AVIATION...FOR THE 05/12Z TAF CYCLE...LCL MVFR CIGS WILL
DRIFT IN AND OUT OF KOTH EARLY THIS MORNING WITH VFR CIGS EXPECTED
FROM LATE MORNING. NORTHERLY WINDS WILL CONTINUE TO BRING SMOKE INTO
THE ROGUE VALLEY WITH KMFR VIS DOWN TO MVFR MOST OF THE DAY WITH VIS
IMPROVING TO VFR BRIEFING FROM LATE AFTERNOON THROUGH EARLY EVENING.
HOWEVER EXPECT INVERSION TO TRAP SMOKE IN THE VALLEY WITH VIS COMING
DOWN TO MVFR AGAIN. TO THE EAST..SHOWERS WILL CONTINUE TO THE EAST
OF KLMT UNTIL MID MORNING. THE ATMOSPHERE IS LESS UNSTABLE TODAY AND
THUNDERSTORMS ARE NOT EXPECTED AT KLMT THIS AFTERNOON. /FB

&&

.MARINE...UPDATED 900 AM PDT WEDNESDAY 5 AUGUST 2015...HIGH PRESSURE
WILL BUILD OFFSHORE AND A THERMAL TROUGH WILL DEVELOP ALONG THE
COAST THEN STRENGTHEN INTO THURSDAY. NORTH WINDS AND SEAS WILL BUILD
TODAY AND REMAIN MODERATE THROUGH THURSDAY MORNING...REACHING
ADVISORY CRITERIA IN THE SOUTHERN OUTER WATERS. WINDS WILL
STRENGTHEN FURTHER THURSDAY AFTERNOON AND EVENING...POSSIBLY
REACHING GALE FORCE OVER THE SOUTHERN OUTER WATERS. A GALE/HAZARDOUS
SEAS WATCH HAS BEEN ISSUED FOR THIS TIME FRAME FOR AN AREA BEYOND 10
NM AND MAINLY SOUTH OF GOLD BEACH. THE THERMAL TROUGH WILL WEAKEN
FRIDAY INTO SATURDAY. NORTH WINDS AND SEAS WILL EASE AT THAT TIME.
-FJB/MSC

&&

.FIRE WEATHER...UPDATED 200 PM PDT WEDNESDAY 5 AUGUST 2015...QUIETER
CONDITIONS TODAY WILL CONTINUE THROUGH THURSDAY. RELATIVELY WEAK
OFFSHORE FLOW WILL HOWEVER BRING LOW HUMIDITIES AND MODERATE TO POOR
OVERNIGHT RECOVERIES TO THE HIGHER ELEVATIONS OF NORTHERN
CALIFORNIA AND SOUTHERN OREGON ALONG AND SOUTH OF THE UMPQUA
DIVIDE.

LATE THURSDAY NIGHT AND INTO FRIDAY, MOISTURE IS EXPECTED TO PUSH
INTO OUR REGION FROM THE SOUTH AHEAD OF AN APPROACHING UPPER LEVEL
LOW. THE RESULTING INSTABILITY WILL LIKELY RESULT IN ISOLATED TO
SCATTERED THUNDERSTORMS, MOSTLY CONCENTRATED TO THE EAST OF THE
CASCADE CREST IN BOTH OREGON AND CALIFORNIA. HAVE THEREFORE ISSUED
A FIRE WEATHER WATCH FOR THESE AREAS, AND WILL ASSESS THE NEED FOR
A RED FLAG TOMORROW, WHEN INPUT IS GATHERED FROM PARTNER AGENCIES
AND HOPEFULLY THE DETAILS BECOME MORE APPARENT IN THE MODEL
OUTPUT. THUNDERSTORM CHANCES WILL REMAIN IN THE FORECAST THROUGH
EARLY NEXT WEEK AS ANOTHER LARGE TROUGH DIGS INTO THE WEST COAST.
