NWS Seattle, WA wrote its last area forecast discussion before the first event at Jun 5, 2:30 AM PST, 2 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SEATTLE WA 330 AM PDT SAT JUN 5 2004 .SYNOPSIS...OCCASIONAL SHOWERS...AND POSSIBLE AFTERNOON THUNDERSTORMS...WILL BE THE RULE TODAY AS COOL UNSTABLE AIR MOVES INTO WESTERN WASHINGTON BEHIND A WEAK PACIFIC COLD FRONT. UNSETTLED WEATHER WILL CONTINUE SUNDAY AND INTO MONDAY AS AN UPPER LOW MOVES SOUTHEAST ACROSS THE AREA. BY TUESDAY THE LOW WILL MOVE DOWNSTREAM AND AN UPPER RIDGE OFFSHORE WILL PROVIDE A RETURN TO DRIER WEATHER. && .DISCUSSION...THE DEEP UPPER LOW OFFSHORE IS NEAR 50N/135W AND CONTINUES TO CURVE SLOWLY NE. MEANWHILE ITS COLD FRONT MADE LANDFALL ALONG THE WA COAST AROUND 2 AM...AND PCPN SPREAD INLAND DURING THE EARLY MORNING HOURS. THE WEAKENING FRONT WILL MOVE E OF THE FORECAST AREA THIS MORNING...WITH A COOL UNSTABLE AIR MASS MOVING INTO WRN WA TODAY. I WILL BUMP UP THE POPS OVER MOST OF THE AREA TO CATEGORICAL ...AND I THINK THE CHANCE OF TSTORMS IN THE FORECAST LOOKS GOOD. THE UPPER LOW WILL BEGIN MOVING SE SAT NIGHT...AS AN UPPER RIDGE BUILDS UPSTREAM ALONG 155W. THE MODELS HAVE BEEN INCONSISTENT WITH THE TIMING OF A SMALL SHORTWAVE FEATURES MOVING THROUGH THE BOTTOM OF THE TROUGH INTO THE AREA SAT NIGHT OR SUN. BUT IT LOOKS LIKE A SAFE BET THAT SHOWERS WILL CONTINUE THROUGH THIS PERIOD...WITH A PUGET SOUND CONVERGENCE ZONE LIKELY SUN AFTERNOON AND TSTORMS POSSIBLE AS THE UPPER LOW MOVES CLOSER. THE LOW SHOULD SLOWLY DIG THROUGH THE AREA SUN NIGHT AND MON...WHILE THE UPPER RIDGE SLOWLY PROGRESSES TOWARD THE PACIFIC NW. IN THE LONGER RANGE IT LOOKS LIKE THE LOW WILL DEVELOP INTO A LARGE TROUGH OVER THE WRN U.S. AS THE MEAN RIDGE POSITION REMAINS OFFSHORE AROUND 145W. THIS SHOULD PROVIDE US WITH GENERALLY DRY NWLY FLOW FROM TUE THROUGH FRI. HOWEVER THE AIR MASS WILL REMAIN MARGINALLY UNSTABLE ON THE W SIDE OF THE TROUGH...WITH ISOLATED DIURNAL SHOWERS POSSIBLE OVER THE CASCADES. IT ALSO WOULDNT BE TOO SURPRISING IF ANOTHER SHORTWAVE TROUGH MADE ITS WAY DOWN THE BACK SIDE OF THE RIDGE TO AFFECT THE AREA. MCDONNAL && .SEW...NONE. .KATX...VCP21/CSR32. &&
