Funnel Cloud in Washington, April 24, 2007

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
300 PM PDT TUE APR 24 2007

.SYNOPSIS...A WEAK COLD FRONT WILL PASS THROUGH THE INTERIOR OF
WESTERN WASHINGTON BY EARLY THIS EVENING. SOME CLEARING WILL OCCUR
TONIGHT AS WEAK HIGH PRESSURE MOVES ACROSS THE AREA. A SERIES OF
WEAK DISTURBANCES WILL BRUSH MAINLY NORTHERN PORTIONS OF WESTERN
WASHINGTON AS THEY MOVE INTO VANCOUVER ISLAND WEDNESDAY THROUGH
FRIDAY. WHILE CLOUDS WILL BE ABUNDANT...LIGHT RAINFALL WILL BE MOST
LIKELY ON THE COAST AND IN THE FAR NORTH INTERIOR. DRY CONDITIONS
WILL DOMINATE THIS WEEKEND.

&&

.SHORT TERM...A WEAK COLD FRONT IS MOVING THROUGH THE INTERIOR
LOWLANDS LATE THIS AFTERNOON AND WILL DISSIPATE OVER THE CASCADES
EARLY THIS EVENING. LIGHT SHOWER ACTIVITY WILL GRADUALLY COME TO AN
END EARLY THIS EVENING BEHIND THE FRONT. A WEAK RIDGE OF HIGH
PRESSURE WILL MOVE ACROSS THE AREA TONIGHT GIVING DRYING AND SOME
CLEARING...THOUGH THE INTERIOR WILL STILL AREAS OF CLOUDS AS LOW
LEVEL MOISTURE LINGERS.

THE MAIN STORM TRACK IS NOW LOCATED WELL TO THE NORTH OF THE AREA.
EXPECT THE NEXT SEVERAL DISTURBANCES TO JUST BRUSH BY WESTERN
WASHINGTON AS THEY MOVE INLAND OVER VANCOUVER ISLAND. THE TAIL END
OF A WEAK DISTURBANCE NOW NEAR 43N 139W WILL MOVE THROUGH THE AREA
WED AND WED EVENING. RAIN IS LIKELY ON THE NORTH COAST AND VERY
LITTLE WILL BE SEEN OVER THE EXTREME SOUTH PART OF THE FORECAST
AREA. IT CONTINUES TO LOOK LIKE THE FORECAST WILL BE PROBLEMATIC IN
THE SEATTLE AREA WITH THE MAIN POPULATION AREA ON THE EDGE. AT THIS
POINT WILL CONTINUE WITH A MOSTLY CLOUDY FORECAST AND A FEW
SPRINKLES THERE.

MODELS WAFFLE ON THE SOUTHEASTWARD EXTENT OF LIGHT PRECIPITATION
WITH A WARM FRONT LATE WED NIGHT AND THU...AND WITH THE TRAILING
DYING COLD FRONT THAT DRAGS THROUGH THE AREA LATER FRI AND FRI
NIGHT. IN THIS PATTERN WE WILL SEE LIKELY POPS AT TIMES ON THE NORTH
COAST WITH ONLY A FEW SPRINKLES AT TIMES AT THE SOUTHEAST FRINGE OF
THE FORECAST AREA. AGAIN SEATTLE REMAINS IN THE BORDER ZONE. A BROAD
BRUSH FORECAST FOR THE ENTIRE PERIOD WITH TEMPERATURES NEAR AVERAGE
LOOKS LIKE THE BEST BET FOR NOW. ALBRECHT

.LONG TERM...FRIDAY NIGHTS DYING FRONT WILL DISSIPATE OVER THE AREA
BY EARLY SATURDAY. THEN IT LOOKS MOSTLY DRY OVER THE WEEKEND WITH
LIGHT SW FLOW ALOFT AND LOW LEVEL ONSHORE FLOW. IN THIS PATTERN
EXPECT AREAS OF MORNING CLOUDS FOLLOWED BY PARTLY TO MOSTLY SUNNY
AFTERNOONS AND TEMPERATURES NEAR NORMAL. MODELS HAVE BACKED OFF ON
THE DEVELOPMENT OF A DEEP UPPER LEVEL OFFSHORE NORTHERN CALIFORNIA
AND AS A RESULT ARE NO LONGER AGGRESSIVE ON RIDGING INTO THE
NORTHWESTERN US. HENCE TEMPERATURES WILL REMAIN CLOSE TO AVERAGE FOR
THIS TIME OF YEAR. AS WE MOVE INTO EARLY NEXT WEEK...WEAK UPPER
TROUGHING WILL MOVE INTO THE AREA GIVING A CHANCE OF A SHOWER...MORE
CLOUDS...AND TEMPERATURES A DEGREE OR TWO BELOW NORMAL. WHILE THE
WORDED FORECASTS BETWEEN THE WEEKEND AND EARLY NEXT WEEK LOOK
DIFFERENT...IT WILL REALLY ONLY BE A NOTCH COOLER AND CLOUDIER...AND
IT DOES NOT APPEAR THAT SHOWER ACTIVITY WILL BE WIDESPREAD. ALBRECHT

&&

.AVIATION...BACK EDGE OF FRONT HAS ABOUT REACHED THE COAST AT 21Z.
CIGS THIS AFTERNOON RANGE FROM OVC010 ALONG THE COAST TO
BKN-OVC020-025 PUGET SOUND REGION. EXPECT GRADUAL CLEARING OF LOWER
CLOUD DECK THIS EVENING WITH CIGS ABV 050 BY 04Z. MODELS BRING NEXT
SYSTEM CROSS WESTERN WA LATE TOMORROW. FOR KSEA...SCT -SHRA TIL 03Z
WITH CIGS 025-030. WINDS REMAINING S-SW 5 TO 8 KTS. MPH. PRANGE
