area forecast discussion
national weather service sacramento ca
342 am pdt Sat apr 20 2019

Synopsis
Showers and thunderstorms are forecast for today as a low pressure
system moves inland. Temperatures will be significantly cooler
today, with a warming trend starting Sunday and lasting through
the middle of next week.

Discussion
A trough will swing inland today which will bring showers and
thunderstorms to the region. Hi-res model guidance and ensemble
forecasts suggest that we could see a few rounds of this activity.

The first round will be later this morning and should stay
confined to northern portion of the valley, in shasta co and
likely east of i-5 likely. The second shot for showers and
thunderstorms will be later this afternoon and evening, with the
potential be more scattered to widespread, especially over the
northern valley and surrounding mountains. Convective ingredients
support heavier rain and perhaps even some small hail.

Temperatures for the day will be 10-15 degrees cooler than
yesterday and much closer to our seasonal normal for this time of
year.

As the low continues to exit the region, high pressure start to
build to our west. Dry and milder weather is expected for Sunday,
with warming accelerating into next week. Expect to see
temperatures about 10-15 degrees above normal again through mid
next week.

.Extended discussion (Wednesday through Saturday)
upper ridge over the southwest u.S. Wednesday starts out the
extended period under fair skies and well above normal
temperatures. Daytime highs Wednesday could reach up to 20 degrees
above normal upper ridge axis shifts east of the state by Thursday
for a little cooling but Thursday should remain dry under the
ridge. Extended models hint at some form of shortwave disturbance
bringing showers across the northeast corner of the state Thursday
evening. Stability progs indicated enough instability for a
thunderstorm threat in this area as well. Models differ on details
so confidence is low but shower threat will remain in the
forecast across the northern zones through Friday. End of extended
forecast looks dry next Saturday but model confidence remains
low.

Aviation
Pacific frontal system will track across norcal today bringing
showers and isolated thunderstorms north and east of sacramento.

Expect temporary MVFR ifr conditions in showers thunderstorms...

otherwise mainlyVFR through 06z Sunday.VFR with improving
conditions after 06z. Winds generally below 15 knots except in
vicinity of thunderstorms.

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.
