Synopsis
Turning warmer and drier into next week with breezy north winds.

Discussion
Upper low will shift east into utah today leaving norcal in a
much drier... But breezy north flow. This will cause temps to warm
back to around 80 degrees today and into the 80's Sunday at
valley locations. North wind gusts from 20 to 25 mph will be
possible over the northern and central sacramento valley from this
afternoon through Monday. The warm-up will continue into Tuesday
with readings from the upper 80's to low 90's for many
locations... As pacific ridge builds eastward.

.Extended discussion (Wednesday through Saturday)
warm and dry weather dominates in the extended period as upper
level ridging from the eastern pacific continues to build over
the area. An upper level low develops over the great basin and
retrogrades over southern california. This will act to limit
warming over the region to some extent. Temperatures across
interior norcal will range from 5 to 10 degrees above seasonal
normals through Friday. Valley highs will be in the low 90s
through at least the end of the week. The foothill and mountain
high temperatures will range from the 60s to the 80s. Northerly
winds continue into Thursday, though not as strong as earlier in
the week. Ek hec

Aviation
Vfr conditions expected for valley TAF sites for the next 24
hours with clear skies. Low level wind shear is possible this
morning through around 15z, with north surface winds around 5kt,
north winds at 200 ft agl around 30 kt. North winds expected to
increase this afternoon gusting to around 20 to 25 kts in the
valley.

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.
