area forecast discussion
national weather service sacramento ca
212 pm pdt Sun aug 19 2018

Synopsis
Near to slightly normal temperatures on Monday, with gradual
cooling and dry conditions through the week. Areas of smoke and
haze will continue, especially near wildfires.

Discussion
Ridge of high pressure has shifted to the east as an upper level
trough continues to move into the west coast. Smoke and haze are
evident this afternoon, especially along the coastal range and the
northern sacramento valley. Afternoon temperatures are running 3
to 7 degrees cooler than this time yesterday, with valley highs in
the mid 80s to mid 90s.

The slow moving upper trough will continue to bring cooler
temperatures across interior norcal through the forecast period,
especially near the delta and adjacent areas as onshore flow
increases. Monday will be noticeably less hot across the area,
although temperatures will remain a few degrees above normal. Look
for valley and foothill highs in the 90s on Monday, dropping to
the mid 80s to mid 90s on Tuesday.

Some smoke improvement will continue early this week with
increased southwesterly winds. Locally southwest winds will pick
up in the afternoon and early evening hours over the high sierra
ridges, with gusts 20 to 30 mph. Thunderstorm chances will likely
remain north of the forecast area, with dry conditions persisting.

Upper level trough is anticipated to lift to the northeast by
midweek, followed by brief upper ridging. Wednesday highs will be
slightly warmer, although temperatures will remain below normal.

.Extended discussion (Thursday through Sunday)
warm weather will continue across interior northern california
late this week as a weak trough pattern lingers along the west
coast. Look for high temperatures to be within a few degrees of
normal.

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.
