(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksgx 231628 afdsgx area forecast discussion national weather service san diego ca 928 am pdt Fri jun 23 2017 Synopsis Strong high pressure will continue to bring hot weather to the southern california interior while the marine layer will dominate near the coast. There is a slight warming trend and less extensive coastal cloudiness for the weekend. A very welcome but gradual cooling trend will develop for much next week. Discussion For extreme southwestern california including orange... san diego... Western riverside and southwestern san bernardino counties... the marine layer is deeper this morning and there was patchy drizzle reported along the coast. There was no measurable precip from the drizzle this morning. Clearing is occurring inland, but will be a challenge along the immediate coast today as the inversion strength on the morning san diego sounding is at an impressive +15c. Temps today will be similar to yesterday, but a couple degrees warmer in the deserts as the ridge becomes a little better oriented with a slight westward shift, and very similar temps elsewhere compared to yesterday. Weak mid level moist S flow around the high will bring some thin moisture into southern california through today with a few cu buildups likely over the mountains but not enough of the prime ingredients to generate showers or storms. For this weekend the ridge strengthens a bit and will bring a warmup for well inland, mountain, and desert locations. The hottest temperatures are still slated for Sunday when the lower deserts could touch 120 degrees again. The excessive heat warnings continue there. It will heat up over the inland empire as well with triple digits there at many locales Sunday and in the mid 90s to around 100f in the mountains below 5000 ft and across the inland valleys of san diego county. A heat advisory continues in effect Sunday for these locales. The western valleys and the coast will continue to be influenced by the marine layer, although it should become a bit shallower due to the decreasing onshore component. For next week, the ridge will gradually weaken, with some break in the heat wave finally for the deserts. Tuesday through Wednesday we're actually along the southernmost flank of an area of increased zonal flow which should bring the greatest cooling along with some periods of gusty winds. Temperatures will settle to near normal to slightly above normal for the remainder of next week. Medium range models are starting to hint at some rebuilding of the 4 corners high by next weekend which would bring another warmup for inland areas. |
Aviation 231541z... Coast valleys... Stratus 15-25 sm inland, with bases 1000- 1200 ft msl, tops 1700-2000 ft msl, and areas of vis 2-5 sm, will clear to near the coast through 1900 utc. Marine layer inversion strength of around 15 deg c. 1900-24 0000 utc, mostly p6sm vis and few-sct clouds AOA 15000 ft msl, except within 3 sm of the coast where bkn-ovc stratus clouds around 1500-2000 ft msl and 5 sm vis may linger. Chance that ksan and kcrq will not clear today. 24 0000- 1600 utc, stratus re-developing 15-25 sm inland, with bases around 600-900 ft msl, tops around 1300-1800 ft msl, areas of vis 1-5 sm and local vis down to 1 4 sm over inland mesas higher coastal terrain. Low confidence that kont will be impacted with stratus fog. Mountains deserts... P6sm vis through Saturday morning. Increasing clouds AOA 15000 ft msl through tonight. Sct cumulus may develop over the mountains during the afternoon, dissipating by sunset. Marine Northwest wind gusts over the outer waters may reach 25 kt during the afternoons and evenings from Sunday through Tuesday, potentially resulting in conditions hazardous to small craft. Otherwise, no hazardous marine weather conditions expected through Tuesday. Beaches A south swell of 3 ft 13-14 seconds 165-170 degrees combined with large tidal swings will result in strong and dangerous rip and longshore currents through this evening. This swell will also produce surf of 3 to 6 ft at orange county beaches and san diego county beaches north of carlsbad. Also, the high tides will likely reach 7+ ft during the evenings through Saturday. Tides this high may result in minor tidal overflow at low lying beaches. The beach hazards statement continues through late Saturday evening. High tide will fall below 7 feet Sunday, lowering the tidal overflow threat. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. Sgx watches warnings advisories Ca...

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. |
