Severe Weather Alert Descriptions

 Special Statement  Statement as of 9:43 am PDT on July 28, 2014


... Very warm weather this week in southwest Washington and
northwest Oregon...

A very warm week is on tap across the interior of southwest
Washington and northwest Oregon. The warmest temperatures will be
in the inland valleys such as the Willamette Valley... the
Columbia River gorge... the Interstate 5 corridor in southwest
Washington... and the Upper Hood River Valley... where values from
90 to 95 are possible through Tuesday... with upper 80s to near 90
later in the week. The Coast Range and the Cascade foothill
temperatures will close to those values as well.

Maintaining proper hydration will be very important for any
outdoor activities planned this week. Avoid extra exertion during
the afternoon and early evening hours. Do not leave children or
pets unattended in cars... as this can be fatal. Many fatalities
that have occurred over the years during hot spell episodes have
taken place on area rivers... including several that occurred
during our last hot spell earlier in July. Take extra care while
engaged in recreation on area rivers this week.

NWS Forecaster Discussion



AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
934 AM PDT TUE JUL 29 2014

.SYNOPSIS...AN UPPER LEVEL RIDGE REMAINS ANCHORED OVER THE GREAT
BASIN AND NORTHERN ROCKIES. UPPER LEVEL LOW PRESSURE LINGERS OFF THE
WEST COAST OF CANADA...AS A RESULT THE PACIFIC NORTHWEST REMAINS
UNDER SOUTH TO SOUTHWESTERLY FLOW ALOFT. THE RESULT IS VERY WEAK
ONSHORE FLOW...ENOUGH TO AFFECT THE IMMEDIATE COASTAL VALLEYS WHILE
THE INTERIOR REMAINS VERY WARM. WEAK DISTURBANCES LIFTING NORTH FROM
CALIFORNIA WILL BRING A CHANCE FOR THUNDERSTORMS AT TIMES TO THE
CASCADES...MAINLY LANE COUNTY. LITTLE CHANGE EXPECTED IN THIS OVERALL
PATTERN THE NEXT SEVERAL DAYS.

&&

.UPDATE...FEW CHANGES WERE MADE TO THE FORECAST THIS MORNING.
SATELLITE IMAGERY SHOWS SOME ALTOCUMULUS LIFTING INTO LANE COUNTY
FROM THE SOUTH. THIS INDICATES A BIT OF MID-LEVEL MOISTURE AND
INSTABILITY...AND IN-CLOUD LIGHTNING WAS DETECTED IN ONE OF THESE
CLOUDS EAST OF EUGENE EARLIER THIS MORNING. A SIMILAR ALTOCUMULUS
BUILDUP IS HEADED TOWARD SANTIAM PASS...AND WOULD NOT BE SURPRISED TO
SEE A STRAY LIGHTNING STRIKE OUT OF THIS CELL EITHER. THUS WE ADDED A
SLIGHT CHANCE OF THUNDER FOR THE LANE COUNTY CASCADES EARLY TODAY AS
WELL AS THIS AFTERNOON.

BELIEVE THE ENVIRONMENT MOVING IN ALOFT OVER EAST LANE COUNTY IS
BETTER CHARACTERIZED BY THE 12Z MEDFORD SOUNDING THAN THE SALEM
SOUNDING. MODELS DO NOT SEEM TO BE HANDLING THE MOISTURE ALOFT VERY
WELL. A WEAK DRY SLOT IS NOTABLE ON WATER VAPOR IMAGERY...HEADED
NORTH FROM THE OR/CA BORDER. THIS COULD PROVIDE THE TRIGGER FOR MORE
NUMEROUS SHOWERS AND THUNDERSTORMS TO DEVELOP IN THE OREGON CASCADES
AS THE DAY PROGRESSES. THIS WAS REFLECTED WELL IN THE MORNING
FORECAST AND MADE FEW CHANGES.WEAGLE

/PREV DISC ISSUED 307 AM PDT TUE JUL 29 2014/

.SHORT TERM...AN UPPER LOW OFF THE B.C. COAST AND AN UPPER LEVEL 
RIDGE ANCHORED INLAND OVER THE WESTERN U.S. WILL BE THE FEATURES 
AFFECTING THE WEATHER FOR THE PACIFIC NORTHWEST THIS WEEK. LIGHT
MOSTLY SOUTHWEST FLOW ALOFT WITH HIGH 500 MB HEIGHTS. THE MARINE
LAYER REMAINS SHALLOW UNDER THE SUBSIDENCE ALOFT AND IS LIMITED TO
THE COASTAL ZONES WITH A LITTLE SEEPAGE UP THE LOWER COLUMBIA RIVER.

VERY SIMILAR CONDITIONS TODAY. THE MAIN DIFFERENCES ARE LOWER 500MB
HEIGHTS FOR A SLIGHTLY COOLER AIR MASS ALONG WITH AN INCREASE IN THE
LOW LEVEL ONSHORE FLOW. THIS WILL KEEP THE MARINE STRATUS ALONG THE
COAST TODAY. LATER TONIGHT INTO WED MORNING AN OLD FRONTAL BOUNDARY
SLIDES INTO THE COASTAL WATERS AND MAY BRING SOME DRIZZLE TO THE
COAST.MARINE STRATUS SHOULD SEEP FURTHER INLAND AND TRY TO EXTEND
INLAND TO NEAR PORTLAND BUT ANYTHING WILL BE VERY BRIEF AND NOT HAVE
MUCH IMPACT. TEMPS INLAND WILL CONTINUE TO BE VERY WARM WITH LITTLE
CHANGE THROUGH THURSDAY.

AS FOR THUNDERSTORM ACTIVITY...ANOTHER BATCH OF MOISTURE ARRIVES INTO
THE SOUTHERN ZONES THIS AFTERNOON. INSTABILITY IS LIMITED FOR CLOUD
GROWTH UP TO THE -30C LEVEL AND WILL LIKELY NEED THE HIGHER TERRAIN
OF THE CASCADES TO INITIATE CONVECTION. SO EXPECT ANY CONVECTION TO
BE ISOLATED AT BEST. HOWEVER WITH THE INCREASED MOISTURE A STRONG 
CELL COULD DUMP A FAIR AMOUNT OF PCPN IN A SHORT TIME. THE PATTERN 
WEDNESDAY AND THURSDAY LOOKS VERY SIMILAR TO TUESDAY...WITH A CHANCE 
OF THUNDERSTORMS AGAIN OVER THE CASCADES IN THE AFTERNOON AND 
EVENING. ONE CHANGE IN THE MODELS...PRECIPITABLE WATER VALUES ARE 
DOWN TO 0.6 INCH FROM 1 INCH OVER YESTERDAYS RUN. 


LONG TERM...THURSDAY NIGHT THROUGH MONDAY. THE RIDGE IN PLACE OVER 
THE WESTERN U.S. WILL REMAIN IN PLACE THROUGH THE END OF THE WEEK. A 
SERIES OF SHORTWAVES ARE FORECAST TO TRAVEL UP THE WEST SIDE OF THE 
RIDGE...POSSIBLY IMPACTING OUR AREA. THESE IMPULSES BRING CHANCES 
FOR THUNDERSTORMS...MAINLY IN THE CASCADES...THROUGH THE WEEKEND. 
MODEL UNCERTAINTY EXISTS ON THE TIMING AND STRENGTH OF THESE 
SHORTWAVES AS MODEL RESOLUTION ACCURACY DECLINES RAPIDLY FURTHER IN 
THE FORECAST PERIOD...ESPECIALLY FOR THESE SMALLER FEATURES. HAVE 
DECREASED POPS FURTHER NORTH ON FRIDAY AS THE MODELS HAVE CONVERGED 
ON A MORE SOUTHERLY TRACK FOR STORM CHANCES...AND DECREASED 
CONFIDENCE OF THUNDER CHANCE OVER THE WEEKEND DUE TO GREAT MODEL 
UNCERTAINTY ON TIMING AND LOCATION. -MCCOY 

&&

.AVIATION...STRATUS AND FOG IS HUGGING THE COAST AND SOME OF THE
COASTAL VALLEYS WITH IFR CONDITIONS. THE STRATUS MADE IT INTO
KKLS THIS MORNING. SATELLITE IMAGERY SHOWS THE STRATUS BEGINNING
TO CLEAR INLAND...AND EXPECT VFR CONDITIONS FOR THE COAST BETWEEN
19 AND 21Z. GUSTY NORTH WINDS CAN BE EXPECTED FOR THE COAST THIS
AFTERNOON AND EVENING. OTHERWISE VFR CONDITIONS FOR THE INLAND
AIRPORTS. SOME MID LEVEL CLOUDS WILL MOVE OVER THE AREA...MAINLY
SOUTH OF KSLE TODAY. THESE CLOUDS WILL INCREASE OVER THE CASCADES
THIS AFTERNOON WHERE THERE MAY BE SOME THUNDERSTORMS. TJ

KPDX AND APPROACHES...VFR PREVAILING NEXT 24 HOURS WITH GENERALLY
LIGHT N-NW SURFACE WINDS. CULLEN/TJ

&&

.MARINE...THERE WILL BE LITTLE CHANGE IN MARINE WEATHER THIS WEEK.
SURFACE HIGH PRESSURE WILL REMAIN OVER THE NE PACIFIC AS A
THERMAL TROUGH HOLDS OVER NORTHERN CALIFORNIA. THE THERMAL TROUGH
WILL RISE SLIGHTLY NORTH IN THE AFTERNOON AND EVENINGS RESULTING
IN A TIGHTER PRESSURE GRADIENT OVER THE OREGON WATERS. GUSTY WINDS
CAN BE EXPECTED AT THESE TIMES...OCCASIONALLY REACHING OR
EXCEEDING 25 KT. THE GRADIENT WILL BE TIGHTEST SOUTH OF TILLAMOOK.
HAVE EXTENDED THE SMALL CRAFT ADVISORY FOR THIS AFTERNOON AND
EVENING TO INCLUDE THE WATERS BEYOND 10 NM SOUTH OF CASCADE HEAD.

THE SEAS WILL PRIMARILY BE DRIVEN BY THE LOCAL WINDS. STEEP SEAS 3
TO 5 FEET WILL DOMINATE THROUGH THE WEEK. THERE ARE SOME
BACKGROUND LONGER PERIOD SEAS THAT MAY OCCASIONALLY SHOW UP ON
THE BUOYS...BUT THESE ARE VERY SMALL...1 FOOT OR LESS...AND LESS
SIGNIFICANT TO THE MARINER THAN THE 3 TO 5 FEET SEAS AT 6 TO 8
SECONDS. THE STEEP SEAS WILL BE A COMBINATION OF WIND WAVE AND
FRESH SWELL WHICH IS NEARLY IMPOSSIBLE TO DISTINGUISH AND HAVE
THEREFORE COMBINED THE SEAS. THE SEAS WILL BE THE STEEPEST WHEN
THE WINDS ARE THE GREATEST...DURING THE AFTERNOONS AND
EVENING...AND ESPECIALLY SOUTH OF CASCADE HEAD AND NEAR SHORE. TJ

&&

.PQR WATCHES/WARNINGS/ADVISORIES...
OR...NONE.
WA...NONE.
PZ...SMALL CRAFT ADVISORY FOR WINDS FROM 2 PM THIS AFTERNOON TO 11   
     PM PDT THIS EVENING FOR COASTAL WATERS FROM CAPE SHOALWATER WA 
     TO CASCADE HEAD OR OUT 10 NM-COASTAL WATERS AND FROM CASCADE
     HEAD OR TO FLORENCE OR OUT 60 NM.
