5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues. |

High pressure in place over the region will bring above normal temperatures with fair skies through the week, except for near persistent conditions along the coast with night through morning low clouds and fog. A slight cooling trend is expected over the weekend with a slight warming trend early next week. Short term (tdy-fri) 20 204 am. Overall, 00z models are in very good synoptic agreement through the period. At upper levels, a rather flat ridge will build over the area. Near the surface, moderate onshore flow will continue. Forecast-wise, typical early-summer conditions are anticipated through the period. With ridge overhead, marine inversion will remain rather shallow, around 1000-1400 feet, today through Friday. Although onshore flow will remain rather strong, expect stratus fog to mainly remain across the coastal plain. However with the subsidence aloft and onshore flow, some areas near the immediate coast could experience limited clearing each afternoon. Other than the stratus fog across the coastal plain, skies are expected to remain mostly clear through Friday. As for temperatures, will anticipate a warming trend through the period with ridge building overhead and limited stratus fog. 00z mos guidance as well as local empirical temperature guidance indicated slightly cooler temperatures through Friday than previously forecast, but still well above normal away from the coast. Warmest temperatures will occur across the mountains, deserts and inland valleys with those areas in the low 100s. For the coastal valleys, temperatures by Thursday Friday will range in the upper 80s to mid 90s. Near the coast, the moderate to strong onshore flow will keep temperatures a bit cooler, but still a couple degrees above seasonal normals. As for winds, the moderate to strong onshore gradients will generate gusty southwesterly winds each afternoon evening across the mountains and deserts with some isolated advisory-level gusts likely in the foothills of the antelope valley (basically the lake palmdale area). Additionally, with some weak northwesterly gradients this evening, there may be some locally gusty sundowner winds across southern santa barbara county. Long term (sat-tue) 20 204 am. For the extended, 00z models continue to exhibit good synoptic agreement through the period. At upper levels, ridge will remain relatively persistent through Monday then will strengthen a bit on Tuesday. Near the surface, moderate to strong onshore flow will continue. Forecast-wise, only minor changes from day-to-day with conditions very typical of early summer. Stratus fog will continue to impact the coastal plain through the period with the possibility of a bit more inland penetration into the lower coastal valleys this weekend. Otherwise, mostly clear skies will continue. As for temperatures, expect a slight cooling trend Saturday Sunday then a |
slight warming trend Monday Tuesday. Gusty southwesterly winds will continue each afternoon evening across the mountains and deserts. Aviation 20 1214z. At 12z, the marine layer depth at klax was about 1500 ft. The top of the inversion was near 3200 ft with a temperature of 28 c. Widespread low clouds in all coastal areas and in the santa ynez valley this morning. Conds were mostly ifr to lifr, except locally low MVFR across the l.A. County coast. Some lifr CIGS may briefly spread into the san gabriel valley and vtu county valleys for a couple of hours early this morning. Expect skies to clear across the valleys and inland portions of the coastal plain by mid morning, and by late morning near the coast. There is a chance that CIGS could linger into the afternoon at some beaches. Expect similar low cloud coverage tonight, with CIGS spreading across the coastal plain and in the santa ynez valley by midnight or shortly thereafter. Klax... Moderate confidence in the 12z taf. There is a 20-30% chance CIGS will persist until as late as 21z. There of 20% chance that CIGS will arrive as early as 04z this evening. Kbur... High confidence in the 12z TAF withVFR conds through the period. There is a 20 percent chance of MVFR vsbys through 17z this morning, and again after 09z tonight. Marine 20 438 am. For the outer waters, high confidence in the forecast, with sca conds thru late Fri night or Sat morning, then winds will diminish. Winds may drop below SCA levels briefly at times, but in general, expect SCA level winds to prevail with steep short period seas. For the inner waters, north of point sal, good confidence in sca level winds during the afternoon evening hours today thru fri. For the inner waters south of point conception, winds and seas are expected to remain below SCA levels thru sun. However, there is a 30% chance of SCA level winds across the western half of the santa barbara channel each afternoon evening thru fri. Lox watches warnings advisories Ca... None. Pz...

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. |
