Area Discussion for - Sacramento, CA

      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus66 ksto 191015 afdsto area forecast discussion national weather service sacramento ca 315 am pdt Mon aug 19 2019 Synopsis Temperatures close to average early this week will return to above average for the second half of the week. Dry weather pattern continues. Discussion Clear skies cover the region early this morning other than some stratus nosing into the west delta from the carquinez strait. Current temperatures range from the mid to upper 40s in the colder mountain valleys to the upper 50s and 60s across the central valley. Very weak trough lingers across the region early this week maintaining temperatures close to average for mid-august with light to moderate onshore flow. Short-wave forecast to brush by to the north on Wednesday, then high pressure will strengthen and northerly flow develop in its wake leading to a return of above average temperatures across the region. Extended discussion (Friday through Monday)

To conclude the work week, mid-level heights will rebound after the passage of a longwave trough to the north. Gradual height rises are to continue into the weekend as an expansive upper ridge takes shape over the southwestern u.S. The amount of warming this pattern shift provides is unknown given differences in the global ensembles. Most notably, the 00z ECMWF ensemble mean has maintained the more stout ridge with 500-mb heights approaching the upper 590 dm range. Meanwhile, the 06z 00z GEFS ensembles deamplify the mid-latitude flow supporting less impressive daily temperatures. At this point, it is safe to say temperatures will remain above average from Friday through the weekend and into the start of next week. Current forecast highs support readings near, to slightly above the 100 degree mark in the valleys while 80s can be found in the mountains. These numbers equate to roughly 5 to 10 degrees above climatology. Given some of the more robust ecmwf solutions, there may be room to raise these numbers. ~bro Aviation Vfr conditions expected the next 24 hours. Some brief lower ceilings possible from marine stratus through 17z, generally sacramento westward. Gusty winds up to 30 knots possible across the delta and its vicinity. Otherwise, typical diurnal wind patterns for summertime in norcal are anticipated. ~bro Sto watches warnings advisories None.

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.
