(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksgx 250414 afdsgx area forecast discussion national weather service san diego ca 913 pm pdt Tue apr 24 2018 Synopsis Fair and seasonal weather will continue this week, with areas of night and morning low clouds and fog west of the mountains. Lower pressure aloft this weekend into next week will bring cooler weather, and extend the marine layer inland. Discussion For extreme southwestern california including orange... san diego... Western riverside and southwestern san bernardino counties... at 8 pm pdt..Satellite imagery showed gathering stratus along the coast as higher clouds thinned. Surface pressure gradients were up to 8 mbs onshore ksan to the lower deserts but remained weak to the ne and little changed from yesterday. Peak wind reports in wind- prone areas of the mts deserts were in the 25 to 30 mph range. The 00z miramar sounding had a weak 4 degree c inversion based near 1200 ft msl. This was a few hundred feet below the weaker inversion yesterday evening. Based on the miramar sounding and other acars soundings, it appears the marine layer inversion is near, or even a bit below where it was last night. Also, the ridge over socal is holding fast. Because of this we may again see some areas of fog forming just inland from the coast and over the higher coastal terrain late tonight and Wednesday morning. Grids and forecast zones have been updated accordingly. From previous discussion... heights gradually decrease Wednesday through Friday as the pattern shifts with a trough developing over northern california. Temperatures will remain above normal again Wednesday away from the coast but look for significant inland cooling Thursday into the weekend. Onshore gradients will increase further and periods of gusty onshore winds will be likely each afternoon and evening. Winds may become strong enough to require a wind advisory by Friday. Much |
cooler weather for Sunday through early next week. Upper level trough will swing by to the north on Friday and Saturday with periods of strong winds possibly continuing into Saturday night. Cooler conditions will continue through at least the middle of next week as another upper level trough deepens over socal Tuesday and Wednesday next week with very cool conditions over inland areas and periods of strong winds possible. Still a lot of disagreement with the strength of the trough but better consensus that it could drop far enough south and with enough cold air aloft to bring a chance of showers to portions of socal. Haven't added any pops to the forecast yet until we have a little better run to run continuity. Aviation 250400z... Coast valleys... Areas of bkn-ovc stratus along the immediate coast will spread inland later tonight, reaching 10-20 miles inland by 09z. Bases will likely lower slightly from current levels and be 600-900 ft msl with tops to 1200 ft msl. Areas of vis 2-4 miles with local vis below 1 mile will occur over higher coastal terrain 07z-15z, and some coastal valleys could have local fog with vis below 1 mile. Most areas will clear 16z-19z wed, with stratus likely developing again Wednesday evening. Otherwise, sct-bkn clouds at above 20000 ft msl will prevail through Wednesday evening. Mountains deserts... Sct clouds at above 20000 ft msl with unrestricted vis will prevail through Wednesday evening. Marine Stronger west to northwest winds will develop in mainly the coastal waters beyond 30 nm each afternoon and evening Friday through Sunday with gusts around 25 knots possible. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. Sgx watches warnings advisories Ca... None. Pz... None.

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. |
