AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
839 AM PDT Sun Aug 31 2014

.Synopsis...
Dry and warm weather to continue through at least mid-week. Near
to below normal daytime highs expected Wednesday through Saturday.

&&

.Discussion...
A ridge of high pressure will strengthen over the region the next
24 hours or so. Light northerly flow will develop in the valley
today to help warm temperatures back up to near yesterdays highs.
No delta cooling influence during the day is not expected. The
ridge will strengthen overnight warming temperatures a few degrees
over todays highs. Monday still looks like it will be the warmest
day this week with highs 95 to around 103 in the central valley.
The warmer temperatures will be over the north end of the valley.

By Tuesday the flow within the valley will reverse direction
becoming up-valley and we should start to see some better stratus
developing along the coast. This will lead to temperatures a few
degrees cooler on Tuesday over Monday`s highs.

A trough will gradually deepen over the west coast from the middle
of the week into next weekend. No precipitation is expected but some
synoptic cooling along with better delta influences is expected late
in the week that could lower daytime highs below seasonal normals.

.Extended Discussion (Thursday through Sunday)

Increasing troughing aloft with lowering heights through the
extended forecast period will result in a cooling trend with
strengthening onshore flow. Temperatures near to slightly below
normal. Significant model differences exist with synoptic pattern
and potential development of a closed upper low along the Northern
California coast near the end of the week.
