Weak to moderate offshore\nflow today and Saturday will weaken for Sunday through Wednesday.\nA slow cooling trend begins Monday, with more substantial cooling\nand increasing precipitation chances late next week.\n\n&&\n\n.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...\nSAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO\nCOUNTIES...\n\n...UPDATED AVIATION, MARINE, AND BEACHES DISCUSSIONS...\n\nSkies are clear this morning under weak offshore flow. Satellite\nwater vapor imagery shows a vort max digging south into the lower\nColorado River Valley with some weak mountain waves becoming\nevident in the lee of the San Bernardino Mountains. So far\noffshore winds remain fairly weak with isolated gusts 25-30 mph in\nthe Cajon Pass. Surface pressure gradients are trending stronger\noffshore to the Great Basin, but are weak to the Mojave Desert\n(-1.8 mb SAN-DAG). Expect gradients and winds to strengthen as\nthe upper trough continues to dig south - peaking at around 25-35\nmph with local gusts to 40 mph in the wind-prone passes, canyons,\nand coastal mountain slopes later this morning into the afternoon.\n\nPressure gradients strengthen slightly on Saturday, especially to\nthe east, though we begin to lose some of the upper level support\nfrom the nearby trough. Not much change in wind strength for the\nnorthern areas expected, though they will be stronger below the\nSan Gorgonio Pass and the coastal slopes of the San Diego County\nmountains as winds turn more easterly. Offshore winds weaken on\nSunday. Otherwise warmer and drier this weekend with highs around\n5-15 degrees above normal for the coastal areas and valleys, and\nnear to around 5 degrees above normal elsewhere. Sunday is\nforecast to be the hottest day, when highs for inland coastal\nareas and the western valleys will be in the upper 80s to around\n90 degrees. \n\nSubtle cooling takes place Monday and Tuesday as the upper ridge \nbegins to weaken and a cut-off low moves by to the south. Weak\nridging builds in ahead of a digging trough off the coast on\nWednesday, maintaining temperatures around 5-10 degrees above\nnormal. Forecast for later in the week remain highly uncertain.\nFor Thursday, around 52% of the ensemble space maintains ridging \nover the Southwest for continued warm and dry weather, while the \nremaining 48% show at least weak troughing across the West Coast\nfor cooler weather and a slight chance of precipitation in So Cal.\nDifferences in the upper pattern continue into Friday, with around\n20% of the ensemble members still showing a ridge and dry weather.\nEven amongst the clusters with some form of troughing, the\nposition of the jet and moisture/heavier precipitation has a lot\nof north-south variation, though general consensus is for light \n(if any) precipitation here.\n\n&&\n\n.AVIATION... \n061130...Clear and VFR conditions today and tonight. Offshore \nnortheast winds will strengthen by late morning (after 17Z) with \ngusts 30-45 kts for coastal slopes, adjacent foothills, and through \nmountain passes. Pockets of LLWS before the stronger winds surface. \nGusts 15-30 kts for portions of the valleys (KONT, KSBD) and lower \ndeserts (KPSP, KTRM). Some decrease after 02Z and overnight, \nincreasing the LLWS where sfc winds taper off. Winds increase again \nafter 10Z Saturday.\n\n&&\n\n.MARINE...\nNo hazardous marine conditions are expected through Tuesday.\n\n&&\n\n.BEACHES...\nHigh tides will exceed 7 feet early each morning through Tuesday, \npeaking Sunday and Monday at 7.4-7.6 feet. Elevated surf will also \ncontinue. High tides and elevated surf arriving Monday will combine \nto generate minor coastal flooding, with chances for moderate \ncoastal flooding along more west-facing beaches where surf will be \nhigher. A Coastal Flood Advisory remains in effect through noon \nTuesday and contains more details. \n\nReminder, tides mentioned have been corrected to reflect the current \ntrends in actual tide observations.\n\n&&\n\n.SKYWARN... \nSkywarn activation is not requested. However weather spotters are\nencouraged to report significant weather conditions.\n\n&&\n\n.SGX WATCHES/WARNINGS/ADVISORIES...\nCA...Coastal Flood Advisory until noon PST Tuesday for Orange County \n     Coastal Areas-San Diego County Coastal Areas.\n\nPZ...None.\n\n&&\n\n$$\n\nPUBLIC...SS\nAVIATION/MARINE/BEACHES...MM\n"
