Fxus66 kmtr 161542 afdmtr area forecast discussion national weather service san francisco bay area 842 am pdt Sun jun 16 2019 Synopsis A few degrees of warming is expected for mainly inland areas on Sunday as high pressure begins to build near the west coast. More widespread and significant warming is forecast for Monday and Tuesday as high pressure strengthens and onshore flow weakens. However, warming at coastal areas will be limited due to persistent onshore winds. Seasonable temperatures, along with areas of night and morning low clouds, are forecast through the end of next week. Discussion As of 08:42 am pdt Sunday... June gloom is in full effect the morning. Morning visible satellite shows a very deep marine layer across much of the bay area, including into the sacramento valley. The marine layer is so deep and moist that widespread drizzle is being reported. Over the last 12 hours automated gauges show the drizzle was heavy enough to accumulate a few hundredths in the hills. Did a quick update early this morning to include more drizzle for the morning hours and extend cloud coverage. Given the deep nature marine layer, burn off will be slow going this morning. Do some expect some afternoon sunshine across the interior, but lingering clouds will remain at the coast. No other updates were made to the near term forecast. Next weather item of focus will be the warming trend and building high pressure. The work week will be warmer than the current weekend, but do want to emphasize this warm up will not even come close to the heat wave from a week ago. Prev discussion As of 2:22 am pdt Sunday... The fort ord profiler indicates a marine layer depth of around 2000 feet, and ir satellite imagery shows coastal stratus has extended well inland filling inland valleys. Ceilings at area airports range from a few hundred feet to 1400 feet. Current temperatures are generally similar to those from yesterday at this time with readings in the lower 50s to around 60. Highs today are forecast to be a little warmer than yesterday's as high pressure aloft begins to build over the eastern pacific and onshore flow weakens. Highs today are forecast to range from the 60s at the coast to the 70s and 80s inland.

The warming trend will continue early in the week as the upper ridge over the eastern pacific builds eastward over california. The building high will compress the marine layer, resulting in less inland development of low clouds and fog by Monday morning, and especially Tuesday morning. The most significant warming on Monday and Tuesday will be across inland areas where some locations could warm to the lower 90s. As a light onshore flow and marine layer will continue, coastal areas shouldn't see too much warming. Tuesday and Wednesday will likely be the warmest days this week. Medium range models indicate an upper trough dropping inland to our east during the second half of the week, pushing the ridge back offshore. This would bring cooler temperatures back to inland areas, but remaining slightly above seasonal normals. Aviation As of 5:05 am pdt Sunday... Onshore flow and extensive marine layer stratus has reached well inland. Morning mixing out of stratus will be slow going, stratus then extending back inland tonight and Monday morning. Vicinity of ksfo... Ifr-MVFR cig, clearing by 21z today. West wind increasing to 15-20 knots by 22z. MVFR cig returning mid to late evening. Sfo bridge approach... Similar to ksfo. Monterey bay terminals... Ifr CIGS through late morning, partial clearing in the afternoon. Ifr CIGS returning in the evening. Marine As of 10:39 pm pdt Sunday... High pressure off the northern california coast will keep strong northwest winds confined to the northern waters through Monday. Light winds can be expected over the central and southern waters.

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.
