Corrected national weather service san diego ca 1257 pm pdt Mon apr 23 2018 Synopsis Weak onshore flow will result in more widespread low clouds and fog nights and mornings, otherwise fair and mild weather will continue this week under weak high pressure aloft. Low pressure will move toward the north coast of california late in the week, strengthening the onshore flow, and deepening the marine layer. Areas of night and morning coastal low clouds and fog will expand into the valleys, along with cooling. Discussion For extreme southwestern california including orange... san diego... Western riverside and southwestern san bernardino counties... areas of fog and coastal stratus have burned off this morning revealing mild and moistly sunny conditions except for a few clouds lingering at some of the beaches. Expect a renewal of coastal fog and low clouds this evening through Tuesday morning. Areas of fog will again affect coastal areas and along the mesas with visibilities as low as 1 sm. Weak high pressure aloft and otherwise benign synoptic pattern will continue a deep marine layer contributing to night and morning low clouds and fog each day through the end of the week, with warm and sunny afternoons each day. Patchy dense fog could bring some impacts near the coast and along the mesas each morning. There will also be areas of brisk winds through mountain passes and into adjacent deserts each evening, but with gusts mainly 35 mph or less. A low pressure trough will develop off the coast of northern california during the latter part of the week. Some model solutions have it going northward this weekend, and others have it |
digging southward, moving into southern california around Sunday. These solutions are bouncing around regarding the intensity of this trough, but especially the timing of it. It could bring rain, or nothing. We'll need much more confidence before adding chances of rain to the forecast. For now, the most responsible forecast is for cooler weather with an expanded marine layer and more extensive coastal clouds. Daytime temperatures look to sink below average by the weekend. Aviation 231950z... Coast... A few patches of low clouds fog remain at the beaches this afternoon. More low clouds fog should develop this evening, again spreading into the coastal areas after 02z Tuesday with bases 400-700 ft msl and tops to 1100 ft msl. Expect areas of fog reducing vis to 3-5 miles and locally 1 mile or less on higher coastal terrain. Low clouds fog likely to spread 5-10 miles inland by 12z tue. Impacts at coastal TAF sites are likely, with some uncertainty about the precise timing. Low clouds fog should clear to the coast between 16z and 18z Tuesday. Valleys mountains deserts... Few-sct clouds at above 25000 ft msl with unrestricted vis through Tuesday. Marine Patchy fog will occur over the coastal waters each night through Wednesday, but visibility should remain above 1 nm. Otherwise no hazardous marine weather is expected through Friday. Skywarn Skywarn activation isnot requested. However weather spotters are encouraged to report significant weather conditions.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
