Synopsis
A few isolated showers possible over the mountains this evening
and then again Sunday night and early next week. A slow cooling
trend through early next week but with daytime highs remaining
above normal.

Discussion
An upper ridge across california has kept dry and warmer than normal
conditions across norcal today. A weak disturbance ahead of a trough
moving in from the northwest overnight may bring an isolated shower
or two mainly along the northern sierra crest over shasta county this
evening. Elsewhere, dry conditions will be seen.

This upper trough breaks down Friday through the end of the
weekend and a slight cooling trend will be seen. Valley high
temperatures in the upper 80s Friday and Saturday will cool even
further to the mid and low 80s by Sunday. A closed low develops
off the coast of socal Sunday in conjunction with a trough moving
across the northern portion of the state. Ensembles indicate there
could be some light rain across the sierra Sunday evening
associated with this passing system.

.Extended discussion (Monday through Thursday)
guidance continues to show a compact upper low to move across
northern baja california early Monday affording a chance for a
few showers over the southern portion of the sierra Monday evening.

While this system quickly advances into the four corners on
Tuesday, amplifying northern stream flow moves into the central
great basin. The western extent of height falls should graze
interior northern california thus bolstering the chance for
mountain showers on Monday and Tuesday across the sierra-cascade
ranges. Forecast soundings show modest instability but a limiting
factor is the amount of dry air below the cloud layer leading to
enhanced evaporative processes. Impacts across the valley will be
an uptick in the dry, northerly winds. Conditions should improve
by mid- week as the upper trough shifts toward the high plains.

The warmest day of the week will be Monday (upper 70s to lower 80s
over the valley) before cold advection brings numbers closer to
climatology. Looking beyond Wednesday, disturbances cutting
underneath an upper ridge across alaska should be monitored. Both
reliable ensemble systems (ecmwf gefs) show a trough passage over
the west coast late next week. ~bro kr

Aviation
Vfr conditions are expected for the next 24 hours at all sites. A
few isolated showers or thunderstorms will be possible over
primarily shasta county this afternoon and evening.

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.
