.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

.SHORT TERM...
High temperatures today will continue to warm to slightly higher
than recent temperatures but still below seasonal averages. The
next closed low pressure system will move south along the
California Coast before finally coming on shore over the LA Metro
area early Friday Morning. This system is expected to bring
increasing clouds to the area but no significant precipitation
throughout the day Friday. Up to 0.10 inch of rain will be
possible with the heaviest shower. Thunderstorms will be possible
over the higher terrain of San Bernardino, however no
significantlyenhanced precipitation is anticipated with these
higher lapse rates in the upper altitudes.

.LONG TERM...
The center of low pressure over southern California on Friday will
move into Colorado on Saturday with lingering low pressure across
southern California on Sunday. There is greater spread across
California for Monday through Wednesday of next week ranging from
weaker low pressure to weaker high pressure.

Dry and much warmer weather is expected for the weekend into early
next week, but with increasing spread in the high temperature
forecasts, especially beyond Monday. With the warming, high
temperatures will go from a few to around 5 degrees below average
on Saturday to a few degrees above average on Sunday and around 5
degrees above average on Monday and Tuesday. High temperatures for
the inland valleys will go from mostly in the 80s on Saturday to
the upper 80s to upper 90s on Sunday and the 90s to around 100 for
Monday followed by a few degrees of cooling for Tuesday.
