Fxus66 kmtr 140535 afdmtr area forecast discussion national weather service san francisco bay area 1035 pm pdt Sun oct 13 2019 Synopsis Little change is expected through Monday. Slight warming is forecast for Tuesday prior to the arrival of a weak system that may produce light rain in the north bay late Wednesday and Wednesday night. Breezy conditions are expected after frontal passage from late Wednesday through Thursday. Slightly warmer and drier conditions are forecast from Friday on into next weekend, along with moderate breezes at times. Discussion As of 8:35 pm pdt Sunday... Evening water vapor satellite imagery shows a weak upper trough currently aligned along the west coast. This trough brought a slightly cooler airmass into our area today, and also enhanced onshore flow. The result was cooler temperatures across nearly our entire region. Downtown san francisco's high of 62 today was 15 degrees cooler than Saturday's high. Little change is forecast as we move into columbus day. Patchy night and morning low clouds will primarily be limited to coastal areas and temperatures will remain close to seasonal averages. A shortwave ridge will briefly build over california late tomorrow and Tuesday, resulting in a slight warm-up on Tuesday. A pacific weather system projected to move into the pacific northwest around midweek is forecast to produce widespread rainfall across western washington and oregon, as well as northwest california. The southern end of a cold frontal rain band may clip the north bay late Wednesday and Wednesday night, although the likelihood of measurable rain south of northern sonoma county is very low. The midweek system will cool our temperatures slightly on Wednesday and Thursday. Locally gusty post-frontal northwest winds are expected from late Wednesday through Thursday, primarily in coastal areas where gusts to 35 mph are possible along the north bay coast on Thursday. These winds will coincide with higher relative humidity

which will lessen fire concerns. Northwest winds will then veer a bit more to the north by the weekend, resulting in slight warming and drying. However, winds are not currently expected to be strong enough to raise significant fire weather concerns through next weekend. Aviation As of 10:35 pm pdt Sunday... For 06z tafs. Patchy low clouds continue to develop along the coast with some inland intrusion visible on satellite. Gradual deepening of the marine layer and expansion of coastal stratus will bring patchy low clouds to coastal terminals overnight. However, it may be one of those night where the stratus moves in and out bringing tempo cigs to the some terminals. Light and locally variable winds will prevail overnight. Vicinity of ksfo...VFR conditions will prevail through the forecast period with patchy low clouds likely peeking through coastal gaps early Monday morning. Light and locally variable winds will prevail overnight. Sfo bridge approach... Similar to ksfo. Monterey bay terminals...VFR conditions will prevail through late tonight. Patchy low clouds may bring temporary CIGS to area terminals between 07z and 14z early Monday morning. Light offshore or locally variable winds expected overnight. Marine As of 8:59 pm pdt Sunday... Light to locally moderate northwest winds will persist across the coastal waters with locally breezy winds over the northern outer waters. Mixed seas will continue through early this week with a light shorter period northwest swell and a light southerly swell. Fresh wind generate short period waves in combination with swells will produce locally hazardous seas over portions of the outer waters beginning this evening. A larger northwest swell will then arrive later this week with forerunners expected in the next couple days. Mtr watches warnings advisories Tngt Sca... Pt arena to pigeon pt 10-60 nm sca...

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
