SYNOPSIS. A weather system will affect the district from late tonight through the end of the weekend with rain and thunderstorms in the valley, along with heavy rain and snow into the Central Sierra. foothills and mountains. Ridge will build into the area for Monday and Tuesday, with morning fog possible. Quick, dry short wave moves through Central California on Wednesday, before ridge builds across the area into the end of next week.

DISCUSSION. For the rest of the afternoon, strong southeasterly winds will continue along the Grapevine and West Side Hills where local gusts up to 55 mph are possible in these locations. Wind Advisories will remain in effect until tonight for the Grapevine and through Saturday morning for the West Side hills.

Going forward into Saturday, deep upper level trough will continue to make its way toward the CA/OR coast. Light precipitation associated with warm-frontal overrunning will begin overnight and increase in coverage into Saturday. Precipitation through the morning in the valley will be mostly north of Fresno County with only light amounts expected. However, heavy orographic snow will begin into the Central Sierra overnight and will increase in intensity through all day Saturday. As such, A Winter Storm Warning will go into effect at 10 PM PST tonight, and will remain in place through Sunday evening. Snow levels will begin around 7500 feet, before falling to 6000 feet by Saturday evening after the passage of a cold front.

Showers and afternoon thunderstorms will become likely Saturday along and ahead of the approaching front. Thunderstorms will be able to produce locally heavy rainfall, lightning, although hail and funnel clouds can not be ruled out. Rainfall will move southward through the day, with precipitation reaching the southern end of the valley by late in the evening. Precipitation totals will remain light, although higher amounts can occur within thunderstorms. Of course with the favored orographical lift, the heaviest precipitation will occur in the foothills and mountains. Little to no precipitation is expected in the Kern County desert.

On Sunday, main upper level low will move southward through Central California, with scattered showers and thunderstorms once again possible in the valley Sunday afternoon. Snowfall will continue all day in the Sierra, with snow levels remaining around 6000 feet. Trough exits the area by Sunday evening, with precipitation ended across the area. Storm total precipitation over the weekend will range from 1/10 to 1/4 inches in Kern County and into the western portion of the valley. Between 1/2 to 2/3 inches is possible in the northern and eastern portions of the valley. Locations in the Central Sierra foothills will receive between 1 to 2 inches of rain below 6000 feet, with locally heavier amounts. Snowfall will range from 3 to 6 inches with locally up to a foot between 6000 and 7000 feet, and between 1 to 3 feet above 7000 feet. Less than 1/10 of an inch of precipitation is expected in Kern County mountains and desert.

Models show precipitation ending late Sunday into early Monday, with a ridge building into the area on Monday into Tuesday. With ample surface moisture and high pressure aloft, morning fog will become an issue on Monday and Tuesday morning. A weak short wave trough moves through Central California on Wednesday, with little to no precipitation expected, but winds might be an issue on Wednesday as the trough exits the area. From Wednesday onward into the end of the forecast period on Friday, flat ridge builds across the region along with dry conditions. However, morning fog will once again become a issue.

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.
