(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksto 162150 afdsto area forecast discussion national weather service sacramento ca 250 pm pdt Tue jul 16 2019 Synopsis Dry weather with seasonably hot temperatures continue, gradually cooling by late this week. Breezy winds through the delta and over the sierra crest at times. Discussion Not much change in the overall pattern as a weak trough lingers along the west coast. Therefore, dry conditions and seasonal temperatures will continue across the region. Wednesday daytime temperatures are expected to be similar to this afternoon, peaking around 93-101 over the central valley, and upper 60s to upper 80s over the mountains. Temperatures will trend a little below normal by the end of the work week, generally 2 to 7 degrees below seasonal normals. Moderate flow through the delta continues, strengthening overnight. Extended discussion (Saturday through Tuesday) To start the weekend, a weak shortwave trough will clip the region with no discernible weather impacts outside of maintaining |
temperatures near climatology. As this feature exits toward the northern rockies, a much more amplified setup evolves across the eastern pacific into the western u.S. From Sunday onward. Ensemble solutions continue to favor a longwave trough over the offshore waters while a strong ridge sits over the four corners region. Northern california generally resides in between these synoptic features so any west east adjustment will alter sensible weather impacts. It does appear the western extent of this mentioned ridge grazes the area affording a potential increase in temperatures. Monsoonal moisture will circulate about the upper high but it is difficult to say if this will lift up to the northern sierra. It is currently a 7 to 8 day forecast so details will likely change in the upcoming days. ~bro Aviation Vfr conditions next 24 hours. Southwest wind gusts 20-30 kts vicinity delta; otherwise, sustained winds generally below 15 knots. Sto watches warnings advisories None. |

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. |
