Area Forecast Discussion National Weather Service Hanford CA 300 PM PST Sun Jan 24 2021

SYNOPSIS. Precipitation will make a return to the region as a disturbance moves through California this evening. This disturbance will be responsible for another period of wet weather tonight and Monday. A major storm system will likely impact Central California Tuesday night through Friday with widespread moderate to heavy precipitation.

DISCUSSION. A cold storm system is diving southward off the Pacific Northwest coast with the surface cold front moving over northern California. Visible satellite imagery shows an impressive and large area of open cell cumulus clouds behind the cold front over the Pacific Ocean indicative of a very cold air mass. Radar imagery shows the leading edge of precipitation beginning to move inland over the SF Bay area and will be moving into the San Joaquin Valley within the next couple of hours. Precipitation will gradually overspread the district through the evening and then become mainly confined to the mountain areas by Monday morning. Precip will continue over the mountains through Monday with SJ Valley showers confined to mainly Kern County and the eastern valley near the foothills. Rain amounts across the SJ Valley are forecast to generally range from a tenth to one quarter of an inch with local amounts up to one half inch possible, mainly along the far eastern side. The Desert will experience rain shadowing which will limit amounts to a tenth of an inch or less. There could some snow in the Desert as well, but generally just a dusting expected. A Winter Weather Advisory is in effect for the Sierra Nevada and the adjacent foothills above 2000 feet from 4 PM Sunday through 4 PM Monday. Snow accumulations of 2 to 6 inches are expected in the Sierra Foothills above 2000 feet. Snow accumulations of 6 to 12 inches are expected in the Sierra Nevada above 5000 feet. Due to the high impacts along the major highway passes in Kern County, a Winter Storm Warning is in effect for the mountain zones in Kern County from 10 PM tonight to 10 PM Monday. Snow accumulations of 4 to 8 inches expected above 4500 feet and 2 to 4 inches from 2000 to 4500 feet. Strong gusty westerly winds also will develop through the Kern County mountain passes and into the Desert later tonight. A High Wind Warning is in effect from midnight tonight through midnight Monday night. The strongest wind gusts will occur just below the mountain passes, especially around Mojave where gusts could reach 80 mph.

Dry weather will prevail for most of Tuesday before another system begins to move in Tuesday night. This 3rd storm system continues to look very wet with the potential for widespread moderate to heavy precipitation from the middle to the end of the week. Preliminary forecast rainfall amounts range from around one half of an inch in the southern San Joaquin Valley to around 2 inches in the central San Joaquin Valley. 1 to 2 inches in the Kern County Mountains, and 2 to 6 inches in the Sierra Nevada and adjacent foothills. Snow levels will begin around 2000 feet Tuesday night then rise to around 4000 feet on Wednesday and around 5500 feet on Thursday. Confidence continues to increase that this midweek storm system could have major impacts, especially given the added concerns with debris flows around the very large burn scars from last summer's wildfires.

AVIATION. Areas MVFR and local IFR in showers across the San Joaquin Valley from 03z through 12z, local MVFR in clouds and showers over the southern San Joaquin Valley. Widespread MVFR and areas IFR in clouds and precipitation across the mountains after 06z Monday. Westerly winds increasing after 03z Monday with gusts to around 45 knots along the West Side Hills and gusts up to 70 knots over the mountains and desert.

AIR QUALITY ISSUES. None.

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.
