PRECAUTIONARY/PREPAREDNESS ACTIONS...

A GALE WARNING MEANS WINDS OF 34 TO 47 KNOTS ARE IMMINENT OR
OCCURRING. OPERATING A VESSEL IN GALE CONDITIONS REQUIRES
EXPERIENCE AND PROPERLY EQUIPPED VESSELS. IT IS HIGHLY
RECOMMENDED THAT MARINERS WITHOUT THE PROPER EXPERIENCE SEEK SAFE
HARBOR PRIOR TO THE ONSET OF GALE CONDITIONS.

A HAZARDOUS SEAS WARNING MEANS HAZARDOUS SEA CONDITIONS ARE
IMMINENT OR OCCURRING. RECREATIONAL BOATERS SHOULD REMAIN IN
PORT...OR TAKE SHELTER UNTIL WAVES SUBSIDE.  COMMERCIAL VESSELS
SHOULD PREPARE FOR ROUGH SEAS AND CONSIDER REMAINING IN PORT OR
TAKING SHELTER IN PORT UNTIL HAZARDOUS SEAS SUBSIDE.

SMALL CRAFT CONDITIONS FOR WIND MEANS THAT WIND SPEEDS OF 23 TO
33 KNOTS ARE EXPECTED. INEXPERIENCED MARINERS...ESPECIALLY THOSE
OPERATING SMALLER VESSELS SHOULD AVOID NAVIGATING IN THESE
CONDITIONS.

A SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS MEANS THAT WAVES WILL
BE STEEP ENOUGH TO CREATE A POTENTIAL HAZARD TO SMALL CRAFT.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
222 AM PDT WED SEP 10 2014

.DISCUSSION...A LONG-DURATION HOT AND DRY PATTERN IS UNDERWAY ACROSS THE
FORECAST AREA AND WILL PRESENT CHALLENGES TO FIREFIGHTING CREWS IN
NORTHERN CALIFORNIA AND SOUTHERN OREGON. UPPER LEVEL RIDGING IS
DOMINATING THE WEATHER PICTURE THIS EVENING AND WILL DO SO THROUGH
THE WEEKEND AT LEAST...BRINGING WELL ABOVE NORMAL TEMPERATURES TO
THE REGION AND PREVENTING ANY CHANCE FOR PRECIPITATION. ENSEMBLE
MODEL DATA SUGGESTS THIS HEAT IS IN THE TOP 10 PERCENT FOR THIS
TIME OF YEAR. AGAIN...GIVEN THAT WE STILL HAVE SIGNIFICANT
WILDFIRE ACTIVITY IN THE FORECAST AREA...WILL BE WEAVING A GOOD
BIT OF FIRE WEATHER CONCERNS INTO THIS DISCUSSION DUE TO THE
POTENTIAL IMPACTS.

A THERMAL TROUGH IS SETTING UP OVER NORTHERN CALIFORNIA AND IS
EXTENDING NORTH INTO SOUTHWESTERN OREGON THIS MORNING...GENERATING
DRY NORTHEASTERLY WINDS OVER MUCH OF SISKIYOU COUNTY.  HIGHER
TERRAIN IN SISKIYOU COUNTY AND THE CASCADES HAVE CURRENT HUMIDITIES
30 PERCENT OR LESS...AND FURTHER DRYING IS EXPECTED THE NEXT
SEVERAL DAYS. AFTERNOON HUMIDITIES IN THE WARMEST LOCATIONS IN
NORTHERN CALIFORNIA WILL EASILY HIT SINGLE DIGITS. AT THE CURRY
COUNTY COAST THE OFFSHORE FLOW WILL RESULT IN WARM TEMPERATURES THIS
AFTERNOON...LIKELY REACHING INTO THE 80S. AT INLAND LOCATIONS...AFTERNOON
TEMPERATURES WILL BE 5 TO 10 DEGREES ABOVE NORMAL UNDER CLEAR
SKIES. THE MARINE LAYER WILL BE PRACTICALLY NONEXISTENT THROUGH
THE WEEK DUE TO DRY OFFSHORE FLOW.

TONIGHT FIRE WEATHER CONDITIONS BECOME MORE CRITICAL AS HUMIDITIES
REMAIN LOW AND EASTERLY WINDS INCREASE SOME. SISKIYOU COUNTY
BOUNDARY LAYER WINDS ARE NOT SUPER IMPRESSIVE SO NO FORMAL FIRE
WEATHER PRODUCTS WILL NOT BE ISSUED AT THIS TIME...BUT POOR HUMIDITY
RECOVERIES WILL CHALLENGE FIREFIGHTING EFFORTS AS FIRE BEHAVIOR
COULD REMAIN ACTIVE ALL NIGHT. FARTHER NORTH OVER THE CASCADES THE
WINDS ARE MORE SIGNIFICANT BUT HUMIDITIES WON'T BE INCREDIBLY LOW.
AGAIN...NO PRODUCTS ARE BEING ISSUED FOR THIS CURRENTLY BUT THE WIND
SPEEDS AND HUMIDITIES COULD CAUSE SIGNIFICANT FIRE BEHAVIOR.
WE'LL CONTINUE TO MONITOR THE LATEST DATA FOR ANY POTENTIAL FIRE
WEATHER PRODUCT ISSUANCES.

ON THURSDAY AND FRIDAY THE THERMAL TROUGH MOVES INLAND...AND
TRADITIONALLY THESE ARE THE HOTTEST DAYS WITH A COOLDOWN OCCURRING
AFTERWARD. IT WILL CERTAINLY BE HOT WITH TEMPERATURES 10 DEGREES
ABOVE NORMAL...BUT THIS IS NOT A TRADITIONAL SUMMER WITH DROUGHT
CONDITIONS AND RECORD HIGH TEMPERATURES...AND THE THERMAL TROUGH
LINGERS THROUGH SUNDAY WITH CONTINUED HOT AND DRY CONDITIONS
EXPECTED. THIS PATTERN WILL UNFORTUNATELY OFFER LITTLE TO NO RELIEF
FOR FIREFIGHTING EFFORTS ACROSS THE AREA. SMOKE WILL BEGIN TO BE
TRANSPORTED NORTHWARD FROM SISKIYOU COUNTY LATE THURSDAY AND SMOKE
MAY BEGIN TO AFFECT THE ROGUE VALLEY.

IN THE EXTENDED...THE GFS PUSHES A SHORTWAVE INLAND EARLY NEXT WEEK
WHICH WOULD BRING COOLER TEMPERATURES TO THE REGION. HOWEVER...AS
HAS BEEN THE CASE...THESE COOLDOWNS IN THE EXTENDED HAVE VERIFIED AS
BEING SHORT-LIVED AND USUALLY MUCH TAMER THAN MODELS HAVE SUGGESTED.
THE ECMWF HAS ALREADY BACKED OFF OF THIS SOLUTION...KEEPING MAINLY
RIDGING OVER THE AREA THROUGH TUESDAY. THE FORECAST REFLECTS A WARM
AND DRY PATTERN IN THE EXTENDED.

&&

.AVIATION...EXPECT AREAS OF IFR/LIFR STRATUS/FOG ALONG THE NORTH
COAST AND COASTAL VALLEYS THIS MORNING CLEARING TO VFR BY 18Z. THE
REMAINDER OF THE AREA WILL REMAIN VFR THROUGH TODAY...EXCEPT FOR SOME
REDUCED VISIBILITY IN WILDFIRE SMOKE OVER WESTERN SISKIYOU COUNTY.
STRATUS MAY BRIEFLY RETURN TO THE COAST EARLY THIS EVENING, BUT
OFFSHORE FLOW STRENGTHENS AND VFR WILL LIKELY PREVAIL OVERNIGHT.
SPILDE

&&

.MARINE...UPDATED 300 AM PDT WED 10 SEP 2014...BOTH OFFSHORE HIGH
PRESSURE AND A THERMAL TROUGH NEAR THE COAST WILL CONTINUE TO
STRENGTHEN. AS A RESULT...NORTH WINDS AND WIND WAVE DOMINATED SEAS
WILL INCREASE...PEAKING OVER THE SOUTHERN OUTER WATERS THIS
AFTERNOON AND EVENING WHEN GALES AND VERY STEEP SEAS ARE LIKELY.
THE NORTH WIND PATTERN WILL PERSIST THROUGH THURSDAY...THEN THE
THERMAL TROUGH WILL WEAKEN AND MOVE INLAND FRIDAY WITH LIGHTER
WINDS AND SEAS OVER THE WATERS. /FB
