.DISCUSSION...
An amplified pattern continues with a long wave trough over the
Great Basin and an Eastern Pacific ridge nosing in over western
Canada. A cool northerly flow persists over California but the

today. The ridge will gradually build inland allowing the warming
trend to continue this week. Temperatures will climb back to near
normal Tuesday then nudge a few degrees above normal Wednesday
through the end of the week.

Dry conditions are expected through the upcoming week with just a
few clouds at times. The models do show a short wave dropping down
over the lower Colorado River Valley Tuesday night and Wednesday,
but moisture is progged to stay to the east of the Sierra.

An north to northeast offshore surface flow is developing and will
bring some breezy to locally gusty conditions to the mountains and
desert. Winds will be strongest during the late night and morning
periods for the next few days but will remain below advisory level.
