area forecast discussion
national weather service sacramento ca
202 am pdt Sun apr 22 2018

Synopsis
Dry and warm through early next week. Chance of a few showers or
thunderstorms over the mountains by mid to late next week.

Discussion
Shortwave trough will pass through the area today, but bring
little to no moisture with it. This will serve to cool
temperatures a few degrees across northern portions of the area,
while southern portions will warm a few degrees from Saturday's
readings. Widespread 80s expected across the valley with 50s-60s
in the mountains. Instability that brought a few storms near the
crest in tuolumne county yesterday will shift southward, so not
expecting any convection today. Could see some locally breezy
north winds across northern sac valley.

Ridging rebuilds for Monday and Tuesday as temperatures warm a few
more degrees, topping out much above normal for late april.

Redding will likely tie or break daily MAX records both days
(airport records for the 24th - 86 in 2002 and 25th - 87 in
2013). Other valley records are in the 90s so not expecting to
break additional records. As ridging begins to the shift to the
east Tuesday into Wednesday in advance of large closed upper low
over the pacific, could see a few afternoon evening showers and
thunderstorms develop near the sierra crest, south of i-80, as
instability is pulled northward. Confidence remains low in just
how widespread this activity may be, but something to watch.

Temperatures will remain much above normal.

Ceo
.Extended discussion (Thursday through Sunday)
high pressure remains over the west thru Thursday as a closed
upper low sits over the eastern pacific. Temperatures will remain
above average and there's a slight chance of diurnal thunderstorms
over the sierra crest.

Friday into the weekend, uncertainty is high as models diverge
significantly on the speed and direction of the closed low
movement. Generally, the upper low and associated surface cold
front approaches the area on Friday, creating a chance for more
widespread showers and afternoon thunderstorms over the coast
range and sierra crest. Temperatures expected to cool down close
to average.

Aviation
Vfr conditions at the TAF sites the next 24 hours. Winds 10 kts
or less except vicinity delta southwest 10-15 kts.

Sto watches warnings advisories
None.

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.
