10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kmtr 231043 afdmtr area forecast discussion national weather service san francisco bay area 243 am pst Wed jan 23 2019 Synopsis Building high pressure along the west coast will result in a gradual warming trend through Saturday, along with mainly clear skies. The dry weather pattern will likely last through the end of the month, with a continuation of seasonably mild days and cool nights. Discussion As of 2:42 am pst Wednesday... Upper level high pressure continues to build off the west coast. Latest overnight satellite imagery shows a few high clouds spilling over the periphery of the ridge. Despite a few high clouds spilling into far norcal, much of the bay area is mostly clear. Clear skies and relatively light winds will lead to a chilly morning. For what it's worth the latest 24 hour trend does indicate many locations are currently running cooler than 24 hours ago - mid 30s to 40s. Given the clear skies and light winds temperatures are likely to drop a few more degrees through shortly after sunrise patchy frost is possible. The upper level ridge is forecast to remain over the region and ultimately strengthen moving inland this weekend. There is a brief ripple late in the week with a weak inside slider, but the next result locally is offshore flow. Therefore, the rest of the work week and next weekend will be rather quiet weather wise. Clear skies and dry conditions will prevail. Temperatures will gradually warm through the period and peak Friday-Sunday with periods offshore flow. Temperatures will warmer to above seasonal levels with highs in the 60s and 70s. Overnight lows on the other hand will remain cool to chilly with clear skies and light winds. |
The question is, when will it rain next? The 00z operational runs of both the ECMWF and GFS keep the bay area dry through 240 hours (feb 1). However, some of the ensemble guidance gives a 25% chance of 0.01" at ksfo around feb 1 or 2. Needless to say the extended forecast will need some watching, but confidence does seem pretty high that the region will remain dry through then end of january. Aviation As of 9:30 pm pst Tuesday... For 06z tafs. High pressure will maintain mainly clear skies across area terminals with the exception of a few high clouds. Generally light winds will prevail through the forecast period. Vicinity of ksfo...VFR conditions will prevail through the period with only a few high clouds expected. Light to locally variable winds will persist. Sfo bridge approach... Similar to sfo. Monterey bay terminals...VFR conditions and light winds will prevail through the period. Marine As of 8:41 pm pst Tuesday...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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. |
