National Weather Service Discussion, WA Link

[Anonymous]

Hey guys and gals! I thought perhaps since weather matters to those that fish, I'd go ahead and attach the 3:00PM Afternoon Discussion from the National Weather Service in Seattle, WA. You can click on the links at the top to change your area being discussed (like if you live in Spokane, you'd choose NE WA and N ID): [ W WA | SW WA and W OR | SE WA and NE OR | NE WA and N ID ]

A quick note, I read the Evening Discussion which comes out at 9PM most nights, the Morning Discussion at around 9AM, and then the Afternoon Discussion around 2:30PM if things are tranquil and around 3:45PM if they are busy and storms are coming in...like our recent huge snow storms. Some of you might already read these discussions, but I find them very intriguing...plus I love meterology and love technical aspects of meterology.

Enjoy!

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
300 PM PST SAT FEB 23 2008

.SYNOPSIS...A FRONT WEST OF CALIFORNIA WILL SPREAD SOME CLOUDS
ACROSS WESTERN WASHINGTON TONIGHT AND SUNDAY...WITH A CHANCE OF
LIGHT PRECIPITATION OVER THE SOUTH PART AND THE CASCADES. AN UPPER
RIDGE WILL BRING DRY WEATHER MONDAY AND TUESDAY...FOLLOWED BY A WEAK
FRONT ON WEDNESDAY. ANOTHER RIDGE WILL CROSS THE REGION THURSDAY...
AND ANOTHER FRONTAL SYSTEM WILL AFFECT THE AREA FRIDAY AND SATURDAY.

&&

.SHORT TERM...THERE IS A WEAK UPPER LEVEL LOW ALONG THE BORDER OF
WRN WA AND SOUTHWEST BRITISH COLUMBIA. THERE IS NO ORGANIZED WEATHER
SYSTEM ASSOCIATED WITH THE LOW THOUGH...AND IN FACT THERE IS LITTLE
CLOUD COVER OVER THE FORECAST AREA.

THE MOST PROMINENT SYSTEM IN THE PICTURE IS THE LARGE WOUND UP
FRONTAL SYSTEM WELL OFF CALIFORNIA...WITH ITS LOW CENTERED NEAR
38N/133W. THIS FEATURE WILL MOVE INSIDE 130W TONIGHT AND THEN WEAKEN
AND HEAD INLAND AROUND EUREKA LATE SUN. THE CLOUD SHIELD AND PERHAPS
EVEN A LITTLE PRECIPITATION ON ITS NORTHERN FRINGE WILL EXTEND INTO
OUR FORECAST AREA LATER TONIGHT AND SUN. THE MAIN THREAT OF
PRECIPITATION WILL BE ASSOCIATED WITH A DEFORMATION BAND THAT THE
MODELS SHOW...DUE IN PART TO THE WEAK UPPER LOW LINGERING OVER THE
BORDER OF WRN WA AND SOUTHWEST BRITISH COLUMBIA. THE AFTERNOON
PACKAGE WILL BE SIMILAR TO THE CURRENT FORECAST...WITH A CHANCE OF
RAIN SHIFTING INTO THE SOUTH PART OF THE FORECAST AREA AFTER
MIDNIGHT AND THEN MOVING EAST INTO THE CASCADES ON SUN.

ON SUN NIGHT THE REMAINS OF THE LOW PRESSURE WILL MOVE EAST OF THE
CASCADES...WHILE AN UPPER RIDGE BUILDS OFF THE PACIFIC NORTHWEST
COAST. THE UPPER RIDGE WILL PROVIDE ANOTHER STRETCH OF DRY WEATHER
FOR THE FORECAST AREA AS IT BUILDS AND PROGRESSES ACROSS THE REGION.
THE RIDGE AXIS WILL PROBABLY SHIFT INLAND MON NIGHT AND THEN EAST OF
THE CASCADES ON TUE. A WEAK FRONTAL SYSTEM WILL APPROACH THE AREA
AND BRING A CHANCE OF RAIN BACK TO THE FORECAST TUE NIGHT. MCDONNAL

.LONG TERM...THE COLD FRONT OF THE SYSTEM MENTIONED ABOVE WILL CROSS
WRN WA ON WED. MOST LIKELY THIS WILL BE A RELATIVELY WEAK FEATURE...
AS IT WILL BE THE FIRST SYSTEM AFTER THE UPPER RIDGE EARLY IN THE
WEEK. FOR NOW THE FORECAST WILL HAVE LIKELY POPS FOR THE COAST AND
MOUNTAINS AND JUST CHANCE OF RAIN FOR THE INTERIOR LOWLANDS. ANOTHER
UPPER RIDGE WILL BRING MORE DRY WEATHER AS IT PROGRESSES INLAND THU
OR THU NIGHT. ANOTHER FRONTAL SYSTEM WILL MOVE THROUGH FRI AND FRI
NIGHT...FOLLOWED BY AN UPPER TROUGH ON SAT. THE LONG RANGE MODELS
ARE IN FAIRLY STRONG AGREEMENT THROUGH THE PERIOD. MCDONNAL

&&

.AVIATION...MOSTLY CLEAR SKIES EXCEPT ALONG THE NORTH SLOPES OF THE
OLYMPICS AND NEAR THE STRAIT THIS AFTERNOON. SCT-BKN MID LEVEL
CLOUDS MAY DRIFT OVER WRN WA OVERNIGHT...AND CIRRUS WILL INCREASE AS
WELL LATER TONIGHT. MOST OF THE CLOUDS AND PRECIP WITH THE SYSTEM
MOVING INTO NRN CALIF WILL STAY WELL SOUTH OF THE AREA. 19

KSEA...MOSTLY CLEAR POSSIBLY BECOMING BKN100 WITH HIGHER CIRRUS
OVERNIGHT. LIGHT NE WIND. 19

&&

.MARINE...OFFSHORE FLOW...NE 10-20 COASTAL WATERS AND STRAIT...NE 10
KTS INLAND WATERS. 19

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
.SMALL CRAFT ADVISORY FOR ROUGH BAR CONDITIONS GRAYS HARBOR.

Also a link to the models that predict our weather -- however, these are EXPERIMENTAL RUNS.

Check it out: http://www.atmos.washington.edu/mm5rt/r ... dates.html

and then click on the most current run or the one you want to view:

12 UTC 23 February 2008 AQ 12-km 12-km 12-km

Once you click that, scroll down to:

3-hour precipitation LOOP 0 6 9 12 15 18 21 24 27 30 33 36 39 42 45 48 51 54 57 60 63 66 69 72

And click the LOOP link. This will then open a new window and allow you to watch incoming systems and what not...it's pretty cool.

Let's just say Northern California is going to get nailed by a powerful sub-980 low this weekend...yikes!!
