AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN FRANCISCO CA 845 AM PST TUE NOV 8 2005 .DISCUSSION...A FEW SHOWERS CONTINUE OVER THE DISTRICT THIS MRNG WITH RADAR ECHOES MOVING S TO N IN RESPONSE TO A SLUGGISH CUTOFF LOW OFFSHORE. THE CUTOFF CENTER IS IN THE VICINITY OF 34/127 AND ITS MOVING SLOWLY E. THIS SYSTEM WILL CONTINUE TO AFFECT THE DISTRICT THRU AT LEAST WED NIGHT AND PROBABLY INTO THU AS ITS FORECAST TO CONTINUE A VERY SLOW MOVEMENT TO THE E OR SE. THE NEW 12Z ETA AND GFS RUNS ARE FAIRLY CLOSE THRU 36 HRS...THEY BOTH PUT THE CENTER OF THE CUTOFF ABOUT 200 NM W OF PT CONCEPTION AT THAT TIME. THIS FOCUSES THE MAIN RAIN THREAT OVER THE SRN PART OF OUR DISTRICT AND BOTH MODELS HAVE THE HIGHEST QPF TNGT S OF SAN JOSE WITH THE SAME PATTERN ON WED. IF SATPIX AND RADAR BEAR OUT THIS TREND TDA WE MAY HAVE TO RAISE POPS OVER THE SRN DISTRICT FOR THOSE PERIODS IN THE AFTN FCST. AFTER 36 HOURS THE ETA AND GFS START TO DIVERGE AND BY THE 60 HR PANEL...00Z FRI...THE GFS HAS THE CUTOFF CENTER WELL TO THE SSW OF THE ETA POSITION. EITHER WAY THE THREAT OF RAIN WILL DECREASE ON THU ...PROBABLY ENDING FROM THE BAY AREA N...FOLLOWED BY A DRY PERIOD AS A FLAT RIDGE BUILDS OVER THE DISTRICT INTO THE WEEKEND. BY SAT THE AIRMASS IS FORECAST TO WARM SIGNIFICANTLY AND THOUGH NO STRONG OFFSHORE FLOW IS FORECAST...ANY SEABREEZES WILL BE WEAK. IT WILL BE A NICE WEEKEND EXCEPT FOR SOME VALLEY FOG IN THE N AND E BAYS... WHICH SHOULD DEVELOP READILY AFTER THE CURRENT RAIN LEAVES THE GROUND WET.
