Area Forecast Discussion National Weather Service Hanford CA 1134 PM PST Sat Dec 14 2019

UPDATE. Issued a Winter Weather Advisory for I-5, although light snow amounts are expected, upslope flow and moisture can provide enough lift for precipitation. Current projected snow levels are below pass level. Possibility that snow doesn't stick or doesn't materialize. Although confidence is only moderate, impacts from any snow near Tejon Pass are large. Wind Advisory was also extended for the Grapevine/I-5 area, and now the whole Wind Advisory has been extended to 4 pm. So any travelers along I-5 during the early morning hours may encounter low visibilities, gusty winds and light snow accumulations. Upslope flow may also necessitate a Dense Fog Advisory for the areas currently in a Wind Advisory, but I will hold off on that for now. However, another threat to keep in mind.

SYNOPSIS. An upper level system will usher in cooler air, light precipitation, and gusty desert winds this afternoon through early Sunday. Ridging Monday and Tuesday will keep weather quiet before another possible storm system impacts Central California during the middle of next week.

AVIATION. Mountain obscuring IFR in the Sierra Nevada and Kern County Mountains overnight. Wind gusts over 40 knots possible over the Kern County Mountains and Deserts through Sunday.Otherwise, VFR conditions expected elsewhere across the central CA interior for the next 24 hours.

AIR QUALITY ISSUES. On Sunday December 15 2019 . Fireplace/Wood Stove Burning Status is: No Burning Unless Registered in Fresno and Kern Counties. Further information is available at Valleyair.org

PREV DISCUSSION. /issued 157 PM PST Sat Dec 14 2019/

SYNOPSIS . An upper level system will usher in cooler air, light precipitation, and gusty desert winds this afternoon through early Sunday. Ridging Monday and Tuesday will keep weather quiet before another possible storm system impacts Central California during the middle of next week.

DISCUSSION . WV showing a fast westerly jet stream extending from 150W all the way through central CA and east into the central CONUS. This jet is moving southward as an upper trough deepens over CA in response to an upper shortwave pushing into northwestern CA. This shortwave is progged to drop southeast through the Great Basin tonight as an inside slider and provide the mountains with a chance of light precipitation and bring a period a strong winds to the Kern County Deserts and the Tehachapi areas where a Wind Advisory remains in effect through Sunday morning.

Once the aforementioned shortwave moves well east of the area Sunday night a dry upper ridge will build into CA and provide for a couple of days with dry weather with frosty mornings as a cool and dry airmass settles in over our area. The drier airmass will limit fog development in the San Joaquin Valley although some patchy fog will still be possible around sunrise on Monday and Tuesday.

Progs are indicating the next trough now moves into central CA Tuesday night and Wednesday although RH progs are indicating that this system will be somewhat moisture deficient with QPF progs indicating a tenth of an inch of liquid precipitation over the Sierra with just a few hundredths of an inch if any over the San Joaquin Valley.

The medium range models and ensemble means are indicating another dry ridge moves inland over CA on Thursday and Friday for a warming and drying trend across the area. This will be followed by a potentially strong low pressure system which will is progged to impact our area next weekend. The models are still showing differences with regard to the strength and timing of this system. We will probably have a better idea with regards to impacts to our area from this system by early next week.

AVIATION . Mountain obscuring IFR in the Sierra Nevada and Kern County Mountains. Wind gusts over 40 knots possible over the Kern County Mountains and Deserts thru 15z Sunday. Local MVFR in low clouds and showers in the San Joaquin Valley and Sierra foothills. Otherwise, VFR conditions expected elsewhere across the central CA interior for the next 24 hours.

AIR QUALITY ISSUES . On Sunday December 15 2019 . Fireplace/Wood Stove Burning Status is: No Burning Unless Registered in Fresno and Kern Counties. Further information is available at Valleyair.org

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.
