.UPDATE...Increased sky cover and added patchy dense fog for
this morning in the Kern County Mountains.

&&

.SYNOPSIS...A warming trend will take place through at least the
middle of next week with above normal temperatures all of next
week. Dry weather will persist across central California through
the forecast.

.DISCUSSION...Per latest webcam and satellite images, as well as
surface observation reports from Tehachapi, we added patchy dense
fog (visibility below 1/4 mile) and bumped up sky cover for the
Kern County mountains. This is expected to continue for the next
2-3 hours, but will likely clear shortly afterward.

.PREV DISCUSSION... /issued 225 AM PDT Sat Oct 21 2017/

DISCUSSION...Upper level northwest flow will be present over
California today...with one more day of below normal temperatures.
Temperatures this afternoon are forecast to be around 5 degrees
below normal for the middle of October.

Upper level high pressure will begin to build over the area Sunday
and continue into next week. Tuesday and Wednesday look to be the
warmest days of the next 7...with daytime highs around 10 degrees
above normal. Little change in the weather pattern through the end
of next week with only subtle temperature changes and dry weather.

Dry and warm looks to be the theme of the weather pattern through
at least the end of the month if not the beginning of November.
According to the Climate Prediction Centers 6 to 10 day and 8 to
14 day outlook...there is a good chance of both above normal
temperatures and below normal precipitation.
