Synopsis
Above average temperatures are expected into next week. Dry
weather pattern continues.

Discussion
Latest satellite imagery indicates high clouds spreading sewd
across interior norcal as upper level trough moves through the
pacnw. Therefore, cloud cover has kept current temperatures
generally 5 to 15 degrees warmer than 24 hours ago.

Above normal temperatures are expected through the forecast
period as the upper trough exits the region, and strong high
pressure builds over norcal. Northerly winds will develop behind
the trough, boosting high temperatures a degree or two compared
to yesterday's readings. Valley locations should see temperatures
in the mid 90s to around 104, while highs in the low 70s to mid
80s are expected over the mountains. These forecast highs will
range from 5 to 10 degrees above normal. Overnight lows will
provide some relief from the hot daytime temperatures, with valley
readings in the 60s.

Extended discussion (Monday through Thursday)
Upper high extends NW from the desert SW over interior norcal as
epac high extends inland. Weak upper low lifts from the SW over
norcal Wednesday into Thursday. This will result in gradual
downward trend in high temperatures, but continued above normal
temperatures with triple digit heat in the northern sacramento
valley and upper 90s elsewhere in the central valley. Dry weather
forecast through the extended period.

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.
