Fxus66 kmtr 190411 afdmtr area forecast discussion national weather service san francisco bay area 911 pm pdt Thu jul 18 2019 Synopsis An inland cooling trend will persist through late week with periods of night and morning low clouds. Temperatures will then warm slightly this weekend before rebounding back to near seasonal normals by next week. Discussion As of 09:11 pm pdt Thursday... Stratus quo. Forecast remains on track for this evening with areas of coastal fog and drizzle already developing. One of our meteorologists already reported drizzle along the northern monterey county coast. This trend will continue through the night and early Friday morning hours. The marine layer this evening is rather deep in the southern portions of our service area, with the fort ord profiler showing a depth up to around 3000 feet while the bodega bay profiler is only showing a depth of about 1300 feet. The upper trough over the pac NW knocks the nosy ridge out north bay, we should see the marine layer deepen up in the northern portions of our service area too. Other than the marine layer, weather remains quiet for now. Temps will start to warm again next week. How much? We'll see how the ridge builds in. Prev discussion As of 01:49 pm pdt Thursday... The modestly deep marine layer in place mixed out well over inland areas this afternoon with mostly sunny conditions and temperatures in the upper 60s to middle 80s. Meanwhile, stratus coverage persists around the marin county coastline, over western portions of san francisco and locally into the monterey bay region. Low clouds will redevelop along the coast before spreading back into the inland valleys overnight with temperatures cooling into the 50s for most locations. Patchy fog and coastal drizzle will also be possible late tonight into Friday morning. The inland cooling trend will continue into Friday as a surface low pressure system currently over northern california shifts offshore. This will result in southerly surface winds which will potentially maintain low clouds along south and southwest facing locations through a good portion of the day on Friday. Little change is forecast heading into Saturday with temperatures generally below seasonal averages.

Building high pressure over the desert southwest will result in a slight warming trend to begin on Sunday, especially for inland areas. However, conditions near the coast will remain cooler as onshore flow persists. The ridge to the east will begin to build westward early next week and allow for temperatures to rebound back to near seasonal averages. However, a deepening trough off of the west coast will prevent the ridge from strengthening too much over our region next week. Aviation As of 4:40 pm pdt Thursday... For 00z tafs. Fractured stratus deck from point arena southward through southern california this evening. Breezy onshore winds this afternoon and beginning to see some fingers of stratus push inland through the monterey bay and golden gate gap. Expect to see some early arrivals of the marine layer over terminals over the new few hours, starting with ksns by 01z. Forecast confidence on lower end given significant difference between model output and potential for some pockets of drier air overnight. Vicinity of ksfo... Sw-w winds 10-15 kt with gusts to 20 kt this evening, then weakening overnight. Marine layer attempting to push through the san bruno gap which will warrant close watch. Otherwise, expecting sct bkn clouds overnight, with bkn posbl after 06z. Sfo bridge approach... Similar to ksfo. Monterey bay terminals... Onshore winds up to around 12kt the rest of the day. Finger of stratus bending towards ksns at this moment and should soon overtake the airport between 00-01z, then overtake kmry later this evening. Lifr-ifr CIGS overnight. Marine As of 08:57 pm pdt Thursday... Split flow will develop overnight through Friday with light to locally moderate northwest winds in the northern outer waters and southerly winds along the coast. The sea state will continue to be dominated by steeper northwest wind waves mixed with a light long period southwest swell. Mtr watches warnings advisories Tngt Sca...

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.
