12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Sacramento CA 300 AM PDT Mon Aug 10 2020
SYNOPSIS. Moderate heat risk persists today over the northern half of the Sacramento Valley. Afternoon thunderstorms possible over higher terrain, mainly Sierra Nevada, through Tuesday. Near normal temperatures midweek, then warming up again by next weekend.
DISCUSSION. Skies are clear across interior NorCal early this morning other than some lingering remnant high clouds left over from Sunday afternoon's Sierra thunderstorms. IR difference imagery shows stratus has returned to much of the NorCal coast, and profiler data indicates the marine layer has deepened slightly. The Delta Breeze is stronger at Travis AFB compared to 24 hours ago, but cooling has yet to be realized. Elsewhere, current temperatures are running slightly warmer across the region compared to early Sunday, and generally range from the lower 50s in the colder mountain valleys to the mid 80s across milder portions of the Sacramento Valley.
Little overall change expected today as mid/upper COL lingers across NorCal. Enough elevated moisture/instability remains within this area of weak flow for a few thunderstorms again later today over the mountains as daytime heating triggers deep convection. Isolated storms may be possible further to the west and north today, over the northern Coast Range and extreme southern Cascade Range.
High temperatures today will be a mixed bag as the return of the Delta Breeze spreads cooling into the Delta region, and slightly cooling into the Sacramento and Stockton areas. Elsewhere, hot weather will continue today with highs similar to Sunday's.
Weak trough develops along the West Coast on Tuesday and Wednesday, pushing most of the late day thunderstorm activity back well to the east of the forecast area by Wednesday. The trough will also result in strengthening onshore flow by this evening which will bring cooler temperatures (back to around average for early to mid-August) for a couple of days.
Trough forecast to weaken by Thursday leading to slight warming as onshore flow slackens.
EXTENDED DISCUSSION (Friday THROUGH Monday). Upper COL over interior NorCal Friday retrogrades offshore as upper ridging from the Desert SW builds over the CWA through the weekend into early next week. Dry weather expected with a gradual warming trend. Greatest departure from normals, upwards of 10 plus degrees by next Monday, will be over the southern half of the CWA under stronger subsidence.

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. |
