Area Discussion for - San Francisco/Monterey Bay Area, CA

      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus66 kmtr 162345 afdmtr area forecast discussion national weather service san francisco bay area 445 pm pdt Tue oct 16 2018 Synopsis Generally weak offshore flow is forecast to persist through at least midweek with temperatures near or above seasonal averages. Onshore winds increase slightly late in the week which should help moisten conditions while daytime temperatures remain mild. A storm system is then forecast to push inland to our north early next week with cooling temperatures and potential for light rain over northern california. Discussion As of 01:52 pm pdt Tuesday... The upper level pattern over the region will change little through midweek as mid upper level high pressure over the eastern pacific extends inland over the pacific northwest and an upper level low remains over the desert southwest. This will keep light offshore winds across the interior and result in seasonably warm conditions each afternoon. Mostly clear conditions are likely overnight with seasonably cool temperatures in the lower elevations while mild temperatures persist in the hills mountains with continued offshore winds. By late in the week, weak onshore flow will potentially develop as the upper level low slowly moves to the northeast and high pressure builds further inland across the west coast. This may allow for a shallow marine layer to develop with the development of coastal stratus during the late night and early morning hours. However, confidence is low at this time and widespread cloud cover is not currently expected through late week. This too may cool conditions a bit near the coast as offshore flow remains confined to the inland areas. This will likely lead to pleasant fall weather conditions over the region through the upcoming weekend. The medium range models continue to suggest a possible pattern shift early next week as an upper level trough approaches the pacific northwest. This would likely at least result in a cooling trend region-wide with rain chances increasing over northern california late Monday into Tuesday. Unsettled weather conditions

look to linger into late next week as well with precipitation dropping as far south as the north bay. However, confidence remains low on widespread rainfall actually developing over our region late in the forecast period. Will need to monitor in the coming days. Aviation As of 4:45 pm pdt Tuesday... Satellite image shows stratus over the waters from point reyes to the santa cruz coast. Stratus has been spreading south into northern mry bay and this could bring CIGS to the mry bay area terminals this evening. These clouds are expected to remain near the coast as the marine layer is shallow and there is weak offshore flow. This is consistent with model guidance which also keeps low clouds out. Vicinity of ksfo...VFR. Models keep stratus confined along the coast but it will have to be watched. Northwest winds to 15 kt decreasing after 04z. Sfo bridge approach... Similar to ksfo. Monterey bay terminals... Ifr CIGS after 05z possibly sooner. Marine As of 04:33 pm pdt Tuesday... High pressure over the eastern pacific coupled with a thermal trough along the coast will maintain generally light to locally moderate northwesterly winds across the coastal waters through much of the forecast period. Mixed swell will continue with a long period southerly swell through mid week and a more moderate period northwest swell. A longer period northwest swell will arrive during the second half of the week. Mtr watches warnings advisories Tngt None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
