200 PM PST THU NOV 6 1997
 
12Z MODELS INITIALIZED WELL THIS MORNING WITH TROF AT ABOUT 130W
AND CD FRNT JUST OFF SHORE AND SLOWLY PROGRESSING INLAND THIS AFTN.
EACH RUN IS SLOWER THAN PREV AND THIS IS VERIFIED WELL WITH SATLT
IMAGERY.  MAIN PROBLEM NXT 24-36 HRS WILL BE THE TIMING OF THE
FRONT AND HOW MUCH PRECIP.  ALL MDLS BRING AT LEAST .10 TO THE CWA
SO AGREE WITH PREV FCST OF LIKELY POPS TONIGHT...EXCEPT FOR YKM
WHICH WILL ONLY GO 50 PCT.  CD FRNT SHOULD BE THRU PDT BY 06Z
TONIGHT WITH A SCNDRY SHRT WV FRI AFTN WITH THE UPPR TROF LINGERING
THRU FRI EVNG.  LOW LVL FLOW SHIFS TO W-NW...IE UP SLOPE INTO BLUES
FRI AFTN...SO WILL KEEP HIGH END OF SCT POPS THERE.  FRZG LVLS DROP
TO ABT 6K FT AND WILL PUT SNOW LVLS AT 5K FT.  SNOW AMTNS DO NOT
LOOK LIKE THEY WILL MEET SNOW ADVY CRITERIA.  RAPID MID AND UPPR
LVL DRYING TAKES PLACE LATE FRI NIGHT SO I BELIEVE FG IS A GOOD BET
BY SAT AM...BUT EVEN MORE SO SAT NIGHT-SUN AS UPPR RIDGE RE-BUILDS.
IN EXTENDED...NXT SYS FCST TO ARRIVE BY MONDAY WITH THE NEXT CHC OF
PRECIP AND THIS ONE LOOKS LIKE A WINDY ONE TOO.  RSC.
