Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Generally light winds will continue through the weekend and into early next week. Southerly winds will increase somewhat by mid- week as an upper trough approaches the region. Mixed moderate northwest swell and a light southerly swell will persist.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kmtr 171226 afdmtr area forecast discussion national weather service san francisco bay area 426 am pst Sat nov 17 2018 Synopsis Widespread smoke and haze at times combining with coastal fog resulting in extended poor air quality and low visibilities over the san francisco bay area should show some improvement first along the immediate coast today then inland Sunday. A mid to upper level ridge has weakened and troughing is already slowly moving in from the west this morning. Additionally forecast models continue to indicate an active pacific weather pattern reaching california next week with the potential for widespread periodic rainfall starting Wednesday and continuing through the latter part of the work week. Discussion As of 4:12 am pst Saturday... Smoke, haze and coastal fog, some of it patchy dense fog with visibilities under 1 4 mile, will combine to keep visibilities low this morning; air quality remains poorest in the bay area. Forecast highs were lowered a few degrees for today from the south bay to the north central coast due to a chilly start, increasing cloud cover, lingering smoke and haze, thus in these areas temperatures may struggle to reach 60f. Stagnant weather continues as a well entrenched albeit much weaker offshore wind pattern remains in place unable to break down as a weaker mid november Sun angle and feeble diurnal warming over land just can't get a foot hold of any kind to generate a decent sea-breeze. Awaiting changes in the mid latitude westerly flow is what is needed to dislodge this pattern, and the early stages of it is already on our door step. A weak 500 mb trough is approx 400 miles west of the CWA with a 925 mb elevated cool front approaching our coastal waters today; elevated fronts typically are weak, but overall cooling and its proximity could cause patch or two of drizzle along the big sur coast today based on the hrrr output which is the only model showing any qpf. Otherwise this feature remains out of reach to generate anything more than cloud cover and advancing higher dewpoint air eastward generating morning coastal fog as we are seeing in the observations and on satellite imagery early this morning. Wind flow remains light today. The next system upstream over the eastern pacific is a 500 mb closed low which weakens as it reaches socal Tuesday. Much earlier model output had this spun up as a leading early week rain generator for us, but this is not the case anymore. However, it'll give traction to a wind reversal which will greatly help clear up the air and improve air quality if not already begun so first on the coastline by later today and then inland Sunday. The GFS and ECMWF have been otherwise consistent that this system will dry out by the time it reaches socal. |
As maritime polar air settles southward to vicinity of 40 degrees latitude over the north pacific next week the door will generously open to wet weather here in california. Increasing moisture from the subtropical latitudes may get ingested into these low pressure systems based on the 00z output (and earlier output) GFS integrated water vapor transport forecasts. Much unlike winter season 2017-2018 with large, ongoing meridional displacement, next week's weather at least shows characteristics more closely to zonal flow. An ongoing relatively large northern hemispheric wavenumber and somewhat distorted polar vortex remain favorable for storm generation with winter solstice still a bit more than 1 month away. Recent GFS and ecmwf 240 hour forecast rain accumulation totals have suggested totals could for the most part reverse early season rain deficits in our CWA and this of course would greatly alleviate fire weather concerns. Aviation As of 04:26 pm pst Saturday... For 12z tafs. A combination of widespread smoke and haze with patchy coastal fog and stratus is affecting the region this morning bringing MVFR ifr vis and or cigs. Expect patchy fog stratus to continue into late this morning for the monterey TAF sites and possibly in the north bay. Latest run of the hrrr smoke model suggests some improvement in smoke late this afternoon and into this evening. This may result in somewhat improved visibilities tonight. However, forecast models suggest more widespread stratus development tonight into Sunday. Generally light winds through the period. Vicinity of ksfo... Ifr MVFR vis due to wildfire smoke. Slant range vis issues will persist. Latest hrrr smoke model suggests some improvement late this afternoon and tonight. More widespread low clouds are expected tonight. Winds will remain light through the period. Sfo bridge approach... Similar to ksfo. Monterey bay terminals... MVFR vis with MVFR ifr CIGS due to a combination of smoke and stratus fog. Lifr vis from fog will be possible until around 16z. An early return of the marine layer is forecast for tonight. Generally light winds. Marine As of 02:14 am pst Saturday... Generally light winds will continue through the weekend and into early next week. Southerly winds will increase somewhat by mid- week as an upper trough approaches the region. Mixed moderate northwest swell and a light southerly swell will persist. Mtr watches warnings advisories Tday None. Public forecast: canepa aviation: as marine: as visit us at |
