area forecast discussion
national weather service sacramento ca
856 pm pdt Tue aug 22 2017

Synopsis
Mountain showers and thunderstorms through Wednesday, then dry
weather returns for the end of the week. Temperatures around
average through mid-week, then warming for the end of the week.

Discussion
Low pressure disturbance off the central coast continues to draw
moisture towards the west into the forecast area this evening.

Areas have settled down south of plumas county this evening and
showers and thunderstorms have ended. Some showers continue to
moves northwest into the area. Models have some of the showers
spreading into mainly eastern shasta county later tonight.

For the most part showers with isolated thunderstorms are
expected. The only major concern may be over burney basin which
has a chance for some scattered thunderstorms over the next
several hours as a weak disturbance moves northward over the area
and may help to provide enough instability. As this disturbance
moves northward overnight by morning any remaining activity will
be north of the forecast area.

Previous discussion
Upper level low continues to spin off the central california
coast this afternoon and will linger through Wednesday. Plenty of
moisture and modest instability has led to another afternoon of
showers and thunderstorms over the mountains. Another round will
be possible on Wednesday, though expecting less coverage and have
confined chances to near the sierra crest. Temperatures will be
near average through Wednesday as onshore flow continues.

Low moves onshore Thursday, opening up into a trough. Moisture and
instability will decrease, ending chances for thunderstorms.

Temperatures will begin to warm with highs topping out a few
degrees above normal. Ridging builds in for the end of the week
into the weekend with a more substantial warming trend. Quiet
weather otherwise.

.Extended discussion (Saturday through Tuesday)
a strong upper level ridge will be set up over the western half of
the us for the extended period. This will bring quiet weather with
warm temperatures for the weekend, highs 97-105 expected in the
valley and 70's and 80's in the higher elevations. The ridge will
start to push to the east early next week and we will start to see
an increase in moisture but mountain thunderstorm chances look to
remain minimal. Temperatures stay warm into early next week but
will start a slow cooling trend.

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.
