area forecast discussion
national weather service san diego ca
915 pm pdt Tue jul 16 2019

Synopsis
Upper-level low pressure moving into the region will create a
deeper marine layer and cooler weather across the area through
Saturday. High pressure building to the east early next week will
create near normal high temperatures by Tuesday. A gradual influx
of monsoonal moisture will create a slight chance of afternoon
thunderstorms near the mountains on Tuesday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

evening update:
stronger pressure gradients this evening running up to 8 mb from the
coast to the lower deserts. The marine layer is stronger and coastal
stratus is already pushing onshore. The threat of dense fog
continues to look less than last night. The forecast is on track and
no updates were made this evening.

Previous discussion, issued at 151 pm pdt:
at 1 pm, water vapor satellite imagery displayed an upper-level
ridge centered around the az nm mexico border, and an upper-level
trough moving into central ca. A coastal eddy was helping to keep
stratus along portions of the coast this afternoon.

Ensembles are in good agreement with the trough moving across ca
through Wednesday, and southwest flow aloft lingering over the
region through Saturday. This will create a deeper marine layer,
developing night morning low clouds and fog further inland into
the valleys and cooler weather across the region. Highs today will
be between 5 degrees below normal to 5 degrees above normal, then
most areas will be just below normal Wednesday, then highs will be
from 5 to 15 degrees below normal Thursday through Saturday.

Ensemble solutions become a bit scattered for the overall pattern
early next week, however confidence is moderate to high that a
ridge will strengthen over the four corners region. This will help
increase our high temperatures to mostly near normal by Tuesday.

Monsoonal moisture will start to move into the region, with
a slight chance of thunderstorms possible over the mountains Tuesday
afternoon. Night morning low clouds will be more restricted to
coastal areas through the 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.
