Marine Weather and Tides
Version 3.4 |
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. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Area Forecast Discussion National Weather Service Sacramento CA 255 AM PST Mon Dec 16 2019
SYNOPSIS. Dry weather will continue with cold mornings through Tuesday. A weak system moves through mid-week with precipitation chances increasing by the weekend.
DISCUSSION. A few high clouds are spilling through the amplifying eastern Pacific ridge into NorCal, otherwise skies are clear early this morning. Temps are chilly with most areas running colder compared to 24 hours ago. Current readings range from around 10 in the colder mountain valleys to the lower 40s across milder portions of the Central Valley.
Dry weather will continue the next couple of days as the short- wave ridge moves overhead. Highs will be close to average for mid-December while overnight lows will be slightly below average. Colder portions of the Central Valley will dip down to around the freezing mark by early Tuesday morning.
The next upstream trough is forecast to split with the southern portion moving into central California Tuesday night into Wednesday. We'll likely see some scattered showers with light QPF across the region, but both the GEFS and EC ensembles indicate better potential to our south.
Focus of precipitation is then expected to shift back into the northern mountains and northern Sacramento Valley on Thursday as warm-advection and moist west-southwest flow returns. The southern half of the Sacramento Valley and northern Sierra south of I-80 will likely remain dry.
EXTENDED DISCUSSION (Friday THROUGH Monday). Except for some possible light showers over the northern mountains, dry weather will prevail on Friday. Then, widespread precipitation could return next weekend as upper troughing develops. However, model differences are evident regarding timing/QPF amounts. Precipitation may spread into the region as early as Saturday afternoon over the Coastal Range, and gradually spread southward overnight. Ensemble guidance suggests moderate to elevated probabilities of total QPF > 1", mainly north of I-80. Snow levels are expected to be around 5000-6500 feet Saturday, and are expected to fall to around 4500-5000 feet Sunday. This system could lead to travel difficulties over the mountains, especially since it is the pre-holiday weekend. Precipitation chances could linger into early next week.
AVIATION. VFR conditions next 24 hours, except local MVFR/IFR conditions from KMYV southward thru 18Z. Winds generally below 10 knots.
STO WATCHES/WARNINGS/ADVISORIES. None.

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. |
