area forecast discussion
national weather service sacramento ca
240 am pdt Sat oct 21 2017

Synopsis
Warming temperatures through early next week. Breezy north winds
and possible fire weather concerns return Monday into Tuesday.

Discussion
Heights thicknesses trend up over the weekend into early next week
as broad upper ridging strengthens over california. Overrunning
warm frontal precip extends into N NW portions of california today
bringing a threat of some light precip. Bulk of precip looks to
remain outside of our forecast area, with slight chances over our
coastal range and shasta mountains today.

Upper ridging strengthens tonight into Sunday shifting storm track
farther north and providing warming of AMS over cwa. Surface high
builds through oregon into great basin tomorrow into Monday as
thermal troughing deepens along the coast. Pressure gradient
increases leading to breezy conditions over interior norcal
beginning Sunday night and continuing into Tuesday. At this time
wind speeds do not look like they will reach advisory criteria,
but strong enough when combined with warming temperatures and
lowering rh to increase fire weather concerns. Near normal
temperatures expected Sunday, then temps warm to upwards of 10 to
15 degrees above normal Mon tue.

Pch
.Extended discussion (Wednesday through Saturday)
amplified upper air pattern forecast to continue across the
eastern pacific and western north america with a strong blocking
ridge centered over the gulf of alaska during the second half of
next week. Slider system clipping the area on Thursday may cool
temperatures slightly, but readings will remain well above average
for late october. Breezy north winds possible in the sacramento
valley behind the system on Thursday.

Aviation
Vfr conditions expected the next 24 hours as shower chances
remain limited to the far northern portion of california.

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.
