area forecast discussion
national weather service sacramento ca
131 pm pdt Sun aug 25 2019

Synopsis
Above normal temperatures through midweek, peaking Tuesday, then
returning to near to slightly above normal by the weekend. Dry
weather continues.

Discussion
Delta breeze will continue each day helping to cool valley
temperatures into the 60s at night with the thermal belt areas
only cooling into the low to mid 70s. The marine layer will hover
around 1000 feet the next several days allowing for the thermal
belt areas to stay warmer at night.

High pressure will strengthen early this week with temperatures
peaking on Monday and Tuesday. Temperatures will warm up to around
100 degrees for both days for most of the central valley to
around 106 over the far north end of the valley. Dry conditions
are forecast through Tuesday.

A weak wave will move northward off the coast Tuesday night and
Wednesday. Some models indicate some showers or isolated
thunderstorms forming over the interior region during this time
period. Nbm continues to indicate dry conditions so have left out
mention of anything for now. Some cloud cover will move over the
area Tuesday night before lifting north and northeast out of the
forecast area Wednesday afternoon and evening. Some cooling is
expected as a result of this of around several degrees for
Wednesday.

Extended discussion (Thursday through Sunday)
No significant changes made from the previous forecast. Ensemble
models show upper ridge over the western u.S. With troughing
digging in off the coast through the extended period. Southwest
flow aloft will keep monsoon moisture south and east of the
forecast area while ridging keeps any pacific moisture north of
the region. Therefore, extended period is expected to remain dry
through next weekend. Development of upper trough off the coast
will bring continued onshore flow and slightly cooler temperatures
Thursday through Sunday although daytime highs are expected to
remain a few degrees above normal. May see breezy winds at times
over the sierra and through the delta but otherwise winds are
expected to remain relatively light under the ridge.

Aviation
Vfr mostly skc conditions through 00z tue. Sustained surface
winds generally below 15 knots, with local gusts up to 25 kts in
the carquinez strait delta.

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.
