Fxus66 kmtr 200517 afdmtr area forecast discussion national weather service san francisco bay area 917 pm pst Tue feb 19 2019 Synopsis After a few days of dry weather, isolated to scattered mainly light rain snow showers are forecast to return to the area by Wednesday and persist into early Thursday morning. Snowfall will be likely limited to the highest elevations, especially across the diablo range and the santa lucia mountains. Dry conditions return on Thursday and continue into at least Friday before rain chances return to northern california during the weekend. Discussion As of 9:17 pm pst Tuesday... Even with very chilly morning low temperatures, plenty of sunshine today allowed afternoon temperatures to warm several degrees over yesterday's at most locations. After morning minimums ranging from the 20s to the lower 40s, today's highs generally ranged from the 40s in the higher elevations, to the upper 50s elsewhere. The warmest locations, santa cruz and healdsburg, reached 61 degrees. Overnight lows tonight are not expected to be not quite as chilly as the previous two as high clouds are moving over northern california ahead of the next weather system expected to affect the area tomorrow and early Thursday. Lows are forecast to generally range from the lower 30s to mid 40s. Meanwhile, an upper level trough is currently digging southward from western canada and is forecast to bring precipitation to northern california later tonight, reaching coastal areas of our cwa by around sunrise. The best chances of precip will occur during the day Wednesday when the upper low swings in to the great basin. Showers to taper off early Thursday when the trough heads into arizona. The trajectory of this system will limit the amount of moisture available to work with, thus, rainfall totals are expected to be meager. Highest amounts are forecast to be in big sur, which could see up to an inch of precipitation. Rainfall totals drop way off from there with most inland valley areas only getting a few hundredths. Snow levels are progged to lower to 2,500-3,000 feet, but this will likely occur after the trough has moved well inland. Thus, only the highest peaks across the southern third of the CWA are expected to receive more than a dusting. Dry weather is then forecast for Friday and Saturday before another trough approaches from the northwest on Sunday. Previous discussion As of 02:03 pm pst Tuesday... Weather conditions today are very similar to those yesterday with temperatures generally in the 50s. While sky conditions are mainly clear over our region, an increase in cloud cover can be seen offshore and to our north ahead of our next approaching storm system. Temperatures will be cold once again tonight, yet should be a few degrees warmer that previous days given the increase in cloud cover and moisture. The latest thinking is that light rain showers will develop during the overnight hours near the coast and locally inland over east bay hills and central coast. The main mid upper level system forecast to drop southward out of the pacific northwest and into california nevada will result in an increase in shower activity on Wednesday during the day. Snow levels are forecast to lower to

between 2,500-3,000 feet a reinforcing shot of colder aid advects southward across the region. This will likely result in additional snowfall in the region's highest peaks, especially over the diablo range, sierra de salinas and santa lucia mountains through early Thursday morning. Meanwhile, convective showers will impact lower elevations with the potential for brief moderate rainfall and small hail given the cold air mass aloft. Overall, rainfall amounts will be on the order of a few hundredths to a few tenths of an inch across the san francisco bay area with locally higher amounts within heavier showers over the central coast. Showers will tapper off by Thursday morning as drier northwest flow returns in wake of the exiting system. Dry weather conditions will then develop region-wide by Thursday night and persist into Friday as a weak shortwave ridge develops aloft. The upcoming weekend looks to start off dry before another mid upper level trough develops over the pacific northwest. This will bring increased chances for precipitation over northern california and potentially down into the northern portions of our region. The storm door appears to remain open with a cool pattern in place, yet confidence in the details remain low at this time given model-to-model and run-to-run inconsistencies. With all this said, a widespread heavy rainfall event does not appear likely within the next 7-10 days. Aviation As of 4:10 pm pst Tuesday... Satellite image shows low clouds offshore that are moving south for the moment. Dry northerly flow will keepVFR conditions through the night but as an upper level system drops down from the pacific northwest clouds will increase on Tuesday. Moisture is limited so there is only a slight chance of showers. We expect CIGS to remain in theVFR range but cannot rule out brief periods of MVFR associated with a heavy shower or from the clouds offshore. This system is an upper-level system with no surface feature so winds will remain west to northwest. Vicinity of ksfo...VFR through tonight. Increasing clouds Tuesday after 15z with CIGS down to 3500-4500 ft. West winds increasing to 15 kt gusting to 20 kt after 09z. Winds increasing to 20 kt with gusts 25-30 kt after 16z. Sfo bridge approach... Similar to sfo. Monterey bay terminals... .Vfr conditions through this evening. Increasing clouds around the bay after 10z with CIGS down to 3500-4500 ft. Scattered showers around southern mry bay after 16z with winds increasing to 15 kt gusting 20-25 kt. Marine As of 8:42 pm pst Tuesday... A low pressure system will drop into the pacific northwest tonight and Wednesday resulting in increasing northerly winds. The winds will remain gusty through Thursday as the low moves into the great basin. This will generate a large northwest swell through Thursday night. Mtr watches warnings advisories Tngt Sca...

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.
