Fxus66 ksgx 212147 afdsgx area forecast discussion national weather service san diego ca 247 pm pdt Mon aug 21 2017 Synopsis A weak low pressure system off the southern california coast will keep high temperatures a few degrees below normal through Wednesday... With areas of low clouds with patchy fog late tonight and Tuesday morning and again Tuesday night and Wednesday morning. There will be gradual warming to near normal high temperatures for Wednesday through Friday... With high pressure over the great basin bringing additional warming with 5 to 10 degrees above normal for next weekend into the following early week. Discussion For extreme southwestern california including orange... san diego... Western riverside and southwestern san bernardino counties... for the remainder of the afternoon and early evening, there remains a slight chance of showers and thunderstorms over the higher mountain peaks of riverside and san bernardino counties and the high desert of san bernardino county... Due to the western extent of a modest monsoonal moisture plume. A decent cumulus field has developed this afternoon in those areas. Chances for convection will quickly end after dark this evening. The troughy pattern along the coast will continue through Tuesday with continued unseasonably deep marine layer influence. Low pressure will weaken Wednesday through Friday, bringing a weaker marine layer, and gradual warming trend to near-normal.

High pressure ridging will develop late in the weekend and into early the following week, bringing some additional warming to a bit above normal conditions, especially for inland locations. In addition, some return mid level monsoonal flow will develop and may eventually bring another chance of convection to the mountains and deserts, although not enough confidence yet to add to the extended forecast. Aviation 211954z... Coast valleys... Through 22 0000 utc, p6sm vis and few clouds AOA 10000 ft msl. 22 0000-1500 utc, stratus will re-develop and move inland 15-20 sm, with bases around 1200-1700 ft msl, tops around 1800-2200 ft msl, and areas of vis 3-5 sm along higher coastal terrain mesas.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
