Synopsis
A slow cooling trend expected through the end of the week as a low
pressure system drops through the pacific northwest. Daytime
temperatures down to near or below normal Thursday and Friday.

Breezy north winds behind the departing low pressure system will
bring elevated fire weather concerns at the end of the week.

Warmer than normal over the weekend with cooling again next week.

Discussion
A stout 595-dm mid-level ridge currently sits just east of the
140w longitude line, roughly 2 standard deviations above
climatology. The eastern extent of this anticyclone has slowly
buckled in response to a weak shortwave passing through the upper
intermountain west. While today's temperatures remain above
average, they have decreased several degrees in some locations
relative to Tuesday. Given semi-persistent dry, northerly winds
over the northern sacramento valley, temperatures around the
century mark have been commonplace. With these wind fields
continuing into the overnight hours, minimal cool down is
anticipated. This would be similar to previous nights which
supported a couple near daily records for nighttime warmth.

Heading south, an active delta breeze has cooled off locations
closer to the i-80 corridor with highs in the low 90s accompanied
by dew points in the upper 50s low 60s.

On Thursday, a more potent shortwave sweeps through eastern
oregon southern idaho which brings modest height falls through
northern california. On its heels will be a secondary feature
primed to scoot through western nevada Friday afternoon. While the
dry, northerly winds should pick up with the initial impulse, they
further strengthen on Friday with gusts possibly reaching 30 to
40 mph over the central northern sacramento valley. This
combination of dry, northerly gusts on top of curing grasses will
enhance fire weather concerns. A fire weather watch remains in
effect from Thursday afternoon through Saturday afternoon. Please
read fire weather related products for more information.

Temperatures on Thursday and Friday will be near average for
mid-june as cooler 1000-500 mb thicknesses accompany the trough
passages. The delta breeze should remain active on Thursday which
will keep temperatures down in the low to possibly mid 80s from
the vicinity of travis afb eastward to sacramento. By Friday, most
of the region can expect dry, northerly flow with temperatures
warming up a few degrees back to the mid upper 80s in most valley
locations. A continued warming trend is likely for the weekend
given a transient ridge tracking through the region. Any
discernible convective chances appear to be on Friday across the
sierra given the shortwave passage. However, the guidance has
generally downplayed this so have kept the forecast dry. ~bro
.Extended discussion (Sunday through Wednesday)
the eastern pacific ridge will weaken as a low off the coast of
western canada will drive southward along the pacific northwest
coast. Ensemble runs are in good agreement the closed low will
settle just offshore near the washington oregon coast. However,
strong troughing associated with this low will work into our
forecast region by the start of the next work week and will
continue to influence our region into late next week. This means a
cooling trend is in store for the region next week. In addition
to synoptic cooling associated with this trough, upper level flow
patterns support onshore flow. This could bring ocean cooled air
inland and spread it through much of interior northern california
by Tuesday Wednesday. Delta influenced areas will likely see the
greatest cooling and breeziest conditions. High temperatures are
expected to drop to 5 - 10 degrees below average on Wednesday for
most of the forecast region. Highs across much of the valley are
only expected to reach into the mid 80s Wednesday with mountain
highs in the 60s to 70s. Sll

Aviation

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.
