.DISCUSSION...
With the axis of the persistent ridge pattern shifted east, a
disturbance has been allowed to move ashore this Sunday. While a
slight disruption in the fog and cooling of temperatures will
be the weather elements mainly influenced by the disturbance,
winds on Saturday were also affected by the approaching
disturbance. Yet, the favored areas around Kern County where
winds gusted between 15 and 30 mph on Saturday afternoon and
evening. At this point, ensemble upper-air analysis does show
the disturbances energy remaining over Extreme Northern
California before moving into the Great Basin.

While no precipitation will make it this far south, the
disturbance will influence temperatures for the early part of
this week. Ensemble analysis then has the high pressure ridge
pattern bouncing back on Monday as the cooling trend bottoms-
out. While temperatures will struggle to reach 65 degrees on
Monday, probability of exceedance of reaching 65 begins its rise
on Tuesday as percentages approach 90 percent on Tuesday. The
remainder of the week will have probabilities of reaching 90
degrees in the 90-100 percent range. While fog will continue all
week under a Rex Blocking High pressure pattern, a disturbance
reaching the West Coast next weekend will re-introduce winds and
cooling across Central California.
