(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksto 252031 afdsto area forecast discussion national weather service sacramento ca 131 pm pdt Sun aug 25 2019 Synopsis Above normal temperatures through midweek, peaking Tuesday, then returning to near to slightly above normal by the weekend. Dry weather continues. Discussion Delta breeze will continue each day helping to cool valley temperatures into the 60s at night with the thermal belt areas only cooling into the low to mid 70s. The marine layer will hover around 1000 feet the next several days allowing for the thermal belt areas to stay warmer at night. High pressure will strengthen early this week with temperatures peaking on Monday and Tuesday. Temperatures will warm up to around 100 degrees for both days for most of the central valley to around 106 over the far north end of the valley. Dry conditions are forecast through Tuesday. A weak wave will move northward off the coast Tuesday night and Wednesday. Some models indicate some showers or isolated thunderstorms forming over the interior region during this time period. Nbm continues to indicate dry conditions so have left out |
mention of anything for now. Some cloud cover will move over the area Tuesday night before lifting north and northeast out of the forecast area Wednesday afternoon and evening. Some cooling is expected as a result of this of around several degrees for Wednesday. Extended discussion (Thursday through Sunday) No significant changes made from the previous forecast. Ensemble models show upper ridge over the western u.S. With troughing digging in off the coast through the extended period. Southwest flow aloft will keep monsoon moisture south and east of the forecast area while ridging keeps any pacific moisture north of the region. Therefore, extended period is expected to remain dry through next weekend. Development of upper trough off the coast will bring continued onshore flow and slightly cooler temperatures Thursday through Sunday although daytime highs are expected to remain a few degrees above normal. May see breezy winds at times over the sierra and through the delta but otherwise winds are expected to remain relatively light under the ridge. Aviation Vfr mostly skc conditions through 00z tue. Sustained surface winds generally below 15 knots, with local gusts up to 25 kts in the carquinez strait delta. Sto watches warnings advisories 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. |
