Synopsis
Slightly cooler today with locally gusty afternoon southwest
wind over higher mountain terrain. Drying and warming next week
with above normal temperatures. Areas of breezy northerly wind
develop tonight into Monday and persist into Tuesday.

Discussion
Upper trough moves across interior norcal today resulting in minor
synoptic cooling and locally gusty southwest wind in the delta and
over higher mountain terrain this afternoon into evening. Some
high cloudiness associated with the short wave over northern
portions of the cwa ATTM will diminish this morning as the wave
progresses. 2 to 5 degrees of cooling expected over the CWA today
with afternoon highs peaking at seasonal values.

Upper trough shifts east into the great basin tonight as surface
and upper high in epac begins to build inland. N-s surface
pressure gradient between kcic-kmfr increases to around 9 mb this
evening with 925 mb winds rising to around 20-25 kts after
midnight. This will result in increasing northerly wind over
portions of interior norcal overnight.

Ams warms Monday under rising heights thicknesses and downslope
flow. North wind of 10 to 15 mph with local gusts to 25 mph can
be expected in northern and western portions of the sacramento
valley, western shasta mountains, and east slopes of the coastal
range. Warming temperatures with downslope wind will result in
lowering humidity and increased fire weather concern. High
temperatures Monday climb to around 3 to 5 degrees above normal
with lower 90s in the central valley and 70s to 80s for the
mountains and foothills.

Heights continue to rise into midweek. MAX temperatures increase
another 2 to 5 degrees Tuesday with a few degrees of additional
warming the following day. Wednesday appears to be the hottest
day of the week with mid to upper 90s in the central valley and
80s to lower 90s for the mountains and foothills. Some breezy
northerly wind continues into Tuesday morning then pressure
gradient decreases.

Pch
.Extended discussion (Thursday through Sunday)
hot and dry weather will continue across the region much of the
latter half of the week as strong high pressure downstream of rex
block over the eastern pacific covers the area. Potentially cooler
weather will return by next weekend as a stronger shortwave drops
down the west coast from the north, and the southern closed low
attempts to approach the coast, but lots of uncertainty in how
this will play out. Have trended temperatures down for next
weekend.

Aviation
Vfr conditions the next 24 hours. Local southwest wind 10-20 kts
vicinity delta and across the higher elevations of the northern
sierra nevada.

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.
