area forecast discussion
national weather service sacramento ca
258 pm pdt Sun jun 25 2017

Synopsis
Cooler, but still remaining above normal into the weekend.

Short term discussion (tonight through Wednesday)
Week upper troughing over the west coast will bring more cooling
on Monday with daytime highs forecast to come in just a little
above normal. A continued strong delta breeze will likely bring
another morning of scattered coastal stratus to the delta. Fair
skies and a bit more cooling expected on Tuesday as weak upper
troughing lingers along the west coast. Upper ridge begins to
rebuild by mid-week bringing the beginning of a warming trend.

Jclapp
.Extended discussion (Thursday through Sunday)
upper ridging moves over the forecast area Thursday bringing dry
weather with some warming. Weak upper troughing follows Friday
with little impact on weather or temperatures. Model differences
exist beyond this point with the ec deepening trough, while gfs
extends upper ridging from epac back over norcal. Both solutions
point to little change into next weekend.

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.
