10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kmtr 161000 afdmtr area forecast discussion national weather service san francisco bay area 300 am pdt Wed oct 16 2019 Synopsis Late rain will be possible across portions of the region from tonight into early Thursday morning as a weak cold front sweep through northern and central california. Cooler, breezy conditions develop in wake of the frontal passage by Thursday afternoon and will continue into Friday. A warming and drying trend is then forecast late in the weekend and into early next week. Discussion As of 03:00 am pdt Wednesday... Patchy fog (dense at times) is being reported over the sonoma valley and northern marin county, down along the san mateo coastline and into the monterey bay region. This is less widespread compared to yesterday morning, yet the marine layer remains around 1,200 feet in depth. Look for a region-wide cooling trend today in advance of an approaching frontal system. This early season system is brining widespread rainfall to washington and oregon with rain lightly to spread into far northwest california later in the day. Light rain will develop as far south as the north bay late this evening and then across the san francisco bay area overnight. While pwat values of 1.50" are advecting inland ahead of this system, the best mid upper level support will remain to our north. As the weakening boundary pushes southward into the central coast Thursday morning, light rain will be possible as far south as the monterey peninsula during the pre-dawn hours while ending to the north. Overall, rainfall amounts from this system will be less than a tenth of an inch for most. Temperatures will continue on the cooling trend Thursday as a colder air mass advects southward across the region in wake of the frontal passage. Brisk northwest winds will also develop and become locally gusty in the afternoon and evening hours, especially along the coast and in the hills. The strongest winds are likely to gust to 35 to 40 mph. The cool, breezy conditions will persist into Friday as well, yet winds will weaken slightly. Another fast-moving system will move across the pacific northwest and northern california from Friday night into Saturday morning. This will bring another slight chance of precipitation to the north bay, yet again rainfall amounts will |
be light. A warming trend is then forecast to begin on Sunday and become more robust early next week as high pressure builds over the region. Thus, look for widespread 70s closer to the coast and 80s across the interior early in the week. Periods of dry, offshore flow will also be possible across portions of the north bay next week as well. However, offshore winds are not forecast to be strong and or widespread. The ensembles indicate above average temperatures are likely to extend into the latter half of next week as well with high pressure remaining the dominate weather feature across the region. Aviation As of 10:44 pm pdt Tuesday... Much less stratus around the bay area compared to yesterday. Marine layer is fairly well established at around 1200 feet so still believe stratus will form later tonight along the sf peninsula and spread into oak and sfo as well as the north bay valleys. It is more questionable whether any stratus spreads into sjc and the south bay tonight. Vicinity of ksfo... MVFR CIGS after 12z with bases around 1000 feet. Clearing after 18z with high clouds moving in. Sfo bridge approach... Similar to ksfo. Monterey bay terminals... Ifr CIGS have returned to mry and sns but most of the mry bay is clear. Therefore may see periods of scattered clouds through 12z. Clearing after 18z. Marine As of 03:00 am pdt Wednesday... Light northwest winds will prevail over the coastal waters through Wednesday. A slight chance of light rain is possible to parts of the waters on Wednesday night associated with a passing front. After the frontal passage, winds will gradually increase.

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. |
