Comment by Patricia Arline Murphy on January 4, 2010 at 2:42pm: Haven't had much in the severe weather to watch out for this season....'course, it's early on yet and I'm sure Mother Nature has plenty of time left yet to whip up something interesting for our winter pleasure :>)

A WINTER STORM WARNING REMAINS IN EFFECT FOR THE OLYMPICS AND WEST

THE FIRST SIGNIFICANT MOUNTAIN SNOWFALL OF THE SEASON...4 TO
12 INCHES...WILL OCCUR MONDAY AND TUESDAY. A STRONG COLD FRONT
WILL BRING COOLER AIR INTO THE REGION WITH SNOW LEVELS LOWERING
TO AROUND 4500 FEET BY NOON MONDAY...AND TO AROUND 3500 FEET
MONDAY EVENING. THIS MEANS STEVENS PASS...WHITE PASS...AND
WASHINGTON PASS WILL LIKELY GET SNOW MONDAY AFTERNOON. THE SNOW

WITH SNOW REACHING SNOQUALMIE PASS.

THE FORECAST CALLS FOR 4 TO 12 INCHES OF SNOW THROUGH TUESDAY
MORNING...WITH HEAVIER AMOUNTS POSSIBLE BETWEEN STEVENS AND
SNOQUALMIE PASS AS A PUGET SOUND CONVERGENCE ZONE DEVELOPS. IN
ADDITION THERE IS A POSSIBILITY THAT A NARROW BAND OF NORTHWEST
WINDS ALOFT FLOWING UNIMPEDED DOWN THE STRAIT OF GEORGIA WILL
CROSS THE CASCADES NEAR OR RIGHT OVER STEVENS PASS CAUSING
LOCALIZED ACCUMULATIONS UP TO 18 INCHES.

SNOW SHOWERS WILL CONTINUE INTO TUESDAY...WITH THE SNOW LEVEL
DROPPING EVEN FURTHER.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

IF YOU ARE PLANNING TRAVEL IN OR THROUGH THE MOUNTAINS...CHECK
THE WEATHER FORECAST BEFORE YOU GO.

Comment by KMel_Tortelli on October 17, 2009 at 9:01pm: ...STRONG THUNDERSTORMS POSSIBLE THIS AFTERNOON...

A RATHER STRONG EARLY FALL COLD FRONT WILL SWEEP NORTHEAST ACROSS
WESTERN WASHINGTON LATE THIS MORNING AND EARLY THIS AFTERNOON. THE
FRONT WILL BE ACCOMPANIED BY A LINE OF HEAVY SHOWERS AND POSSIBLY
A FEW THUNDERSTORMS.

BEHIND THE FRONT...THE AIR MASS WILL BECOME UNSTABLE AS COOLER AIR
MOVES IN ALOFT MAKING THE REGION RIPE FOR THE DEVELOPMENT OF
THUNDERSTORMS. THIS INSTABILITY WILL BE COMBINED WITH STRONG WIND
SHEAR IN THE MID LEVELS OF THE ATMOSPHERE. THAT COMBINATION BRINGS
ABOUT THE POTENTIAL FOR ROTATION TO DEVELOP IN ANY STRONG
THUNDERSTORMS THAT DO DEVELOP DURING THE AFTERNOON HOURS.

ALTHOUGH TORNADOES ARE RARE IN WESTERN WASHINGTON...WHEN WE DO GET
THEM IT IS NORMALLY UNDER SITUATIONS SIMILAR TO THIS WHEN THEY
HAPPEN...BUT EVERYTHING HAS TO COME TOGETHER JUST RIGHT.

THE NATIONAL WEATHER SERVICE WILL BE MONITORING THE SITUATION
CLOSELY THROUGH THE EVENING HOURS AND WILL ISSUE STATEMENTS AND
WARNINGS AS NEEDED. WE ARE ACTIVATING THE SKYWARN SPOTTER NETWORK
AT THIS TIME FOR THE POTENTIAL AFTERNOON CONVECTION AND ARE
ASKING FOR CALLS RELATED TO UNUSUAL CONVECTIVE ACTIVITY.

Comment by Leon Dabbs on October 4, 2009 at 12:21pm: SKYWARN: normal NETS ON CRESTLINE on WED
NIGHT @2000PM / TABLE MT. ON SUNDAY @ 1800 HRS FLASH FLOOD STATUS: NONE
122 DAYS NO R.F UPDATED RECORD
SYNOP: A TROUGH OF LOW PRESSURE HAS DEEPENED THE MARINE LAYER AND BROUGHT HIGHER HUMIDITIES TO THE WEST FACING MOUNTAINS SLOPES TO 5200 FEET. THERE IS A CHANCE FOR A FEW LIGHT SHOWERS TODAY BUT IF ANY PRECIPITATION FALLS IT WILL BE SPOTTY. TODAY WILL BE WINDY...ESPECIALLY IN THE MOUNTAINS AND DESERTS. THE COOL AIRMASS WILL LINGER THROUGH WEDNESDAY...THEN BUILDING HIGH PRESSURE WILL BRING GRADUAL WARMING THURSDAY THROUGH SUNDAY.
Hope all are having a great weekend . Best regards Leon.

Comment by Leon Dabbs on August 21, 2009 at 12:38am: Monsoonal flow from Baha Califonia will increase the moisture content and create thunderstorm acativity in our local mountains and deserts. With such conditions flash floods and dry lightening increases. Many of our forest fires start because of dry lightening. This coming weekend will require a strong watch. Leon Montclair, CA

0402 AM CDT WED AUG 05 2009

VALID 081200Z - 131200Z

..DISCUSSION

00Z ECMWF/GEFS GUIDANCE REMAIN IN RELATIVELY GOOD AGREEMENT WITH THE
OVERALL LARGE SCALE PATTERN AND EVOLUTION OF THE WESTERN STATES
UPPER TROUGH THROUGH THE END OF THE WEEK. THIS UPPER TROUGH WILL BE
CHIEFLY RESPONSIBLE FOR THE MOST ORGANIZED/APPRECIABLE SEVERE
POTENTIAL ACROSS THE NORTHERN TIER OF THE COUNTRY INTO THE
WEEKEND/EARLY NEXT WEEK...AS THIS SYSTEM ADVANCES TOWARD THE CENTRAL
CANADIAN PROVINCES THIS WEEKEND.

DAYS 4/5 SATURDAY AND SUNDAY...CONTINUED NORTHEASTWARD PROGRESSION
OF THE UPPER TROUGH TOWARD THE NORTHERN HIGH PLAINS/CENTRAL CANADA
SHOULD RESULT IN THE DOWNSTREAM/EASTWARD DEVELOPMENT OF A SEVERE
RISK ACROSS THE NORTHERN PLAINS/UPPER MIDWEST AND EVENTUALLY WESTERN
GREAT LAKES VICINITY THROUGH SUNDAY. UNCERTAINTY REGARDING THE
SPECIFIC MAGNITUDE OF THE SEVERE THREAT EITHER DAY PRECLUDES AN
OUTLOOK AREA AT THIS TIME.

DAY 6/MONDAY AND BEYOND...AS THE UPPER TROUGH/ASSOCIATED COLD FRONT
TRANSITIONS EAST-SOUTHEASTWARD...SEVERE TSTMS MAY BE A POSSIBILITY
ACROSS PORTIONS OF THE OHIO VALLEY/LOWER GREAT LAKES AND NORTHEAST
STATES ON MONDAY...AND PERHAPS INTO DAY 7/TUESDAY.
