area forecast discussion
national weather service sacramento ca
126 pm pdt Sun sep 23 2018

Synopsis
Slightly cooler today with locally gusty afternoon
southwest wind over higher mountain terrain. Drying and warming
next week with above normal temperatures. Areas of breezy
northerly wind develop tonight into Monday and persist into
Tuesday.

Discussion
Water vapor and model analysis showed some high level clouds
moving across northern california ahead of a shortwave
disturbance. An area of subsidence with the upper level front was
beginning to slide across the northwest coast of california and
across central oregon during the mid afternoon. Temperatures
across the region ranged from the mid to upper 70s to the lower to
mid 80s.

Latest model forecasts continue to show the trough passage on
track this afternoon into the evening, which will bring an
increasing pressure gradient post frontal passage. As a result,
north winds across the valley will increase. In combination with
dry conditions, critical fire weather conditions will result and
outdoor burning is not recommended. Expecting wind gusts as high
as 25 mph for the valley and up to 30 mph for the sierra.

High pressure will return to the region and bring a slight warm up
back into the 5 to 10 degrees above normal range by mid week.

.Extended discussion (Thursday through Sunday)
hot and dry weather will continue across the region much of the
latter half of the week as strong high pressure downstream of rex
block over the eastern pacific covers the area. Potentially
cooler weather will return by next weekend as a stronger shortwave
drops down the west coast from the north, and the southern closed
low attempts to approach the coast, but lots of uncertainty in how
this will play out. Have trended temperatures down for next
weekend.

Aviation
Vfr conditions the next 24 hours. Local southwest wind 10-20 kts
vicinity delta and across the higher elevations of the northern
sierra nevada.

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.
