331 pm pdt Sat aug 17 2019

Synopsis
Near or below average temperatures expected through Monday.

Gradual warming trend through next week. Dry weather continues.

Discussion
Afternoon temperatures are running 10 to 20 degrees cooler than
24 hours ago across interior norcal, with valley temperatures
in the mid 80s to 90s. The deepening marine layer (about 2500
feet as of this afternoon), and enhanced onshore flow through the
delta has provided relief from the earlier week hot temperatures.

Forecast soundings and ensemble probabilities indicate marine
stratus likely advecting into the delta region the next couple of
nights mornings. Otherwise, mostly clear skies will prevail.

This cooling trend will continue tomorrow, especially in the
delta influenced areas as weak upper level trough lingers across
the region. Sunday highs will be 3 to 8 degrees cooler than
today, with valley locations in the mid 80s to mid 90s, and low
60s to low 80s over the mountains. Similar readings are expected
on Monday, with daytime temperatures near or slightly below
normal for this time of year.

Looking beyond Monday, ensembles indicate increasing heights
across the region as high pressure gradually rebuilds. Therefore,
onshore flow is forecast to weaken allowing for some warming in
the delta influenced areas. Temperatures will trend slightly above
average on Tuesday. Most valley locations should see temperatures
generally in the low to mid 90s, while highs in the upper 90s are
expected over the northern sacramento valley.

Extended discussion (Wednesday through Saturday)
Ensemble guidance is in good agreement high pressure will remain
in place through the extended forecast period. Warmest day is
forecast to be Thursday with high temperatures right around the
century mark across interior ca. A very slight cooling trend is
then expected going into next weekend.

Aviation
Vfr conditions next 24 hours. Breezy evening, gusts 15-25 kts
across interior california 22z - 06z Sunday. Gusty winds up to 35
kts in delta vicinity. Href and NAM guidance indicate the
possibility of clouds tomorrow morning in the delta region. &&

Sto watches warnings advisories
None.

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.
