.DISCUSSION...
The ridge of high pressure that brought us the record-breaking
triple digits continues to hang around. Latest model ensembles
are in a very strong agreement that the ridge moves east through
the weekend into early next week. The setup will help bring
temperatures down but will remain above average for the next
several days.

There is a 40 to 85 percent probability of triple digits for
Sunday in the San Joaquin Valley. However, the probabilities of
triple digits drop to 25 percent or less in most spots on
Monday. Over the next couple days, the probabilities of high
temperatures of at least 90 degrees decrease slowly down to a 60
to 85 percent probability on Thursday, October 10.

Model ensembles are in an agreement that a trough slides into
the Pacific Northwest bringing in cooler temperatures. However,
the probabilities are at 45 to 75 percent for high temperatures
of at least 85 degrees beginning Friday which is around 5
degrees above average. This bodes well with the latest CPC 6-10
and 8-14 day outlooks which have a 50 to 70 percent chance of
above average temperatures. However, the CPC outlooks have near
normal precipitation in both 6-10 and 8-14 day outlooks which
is not much as the daily climatology has 0 to 0.01 inches of
precipitation.
