AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
955 PM PDT Sat Aug 30 2014

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

&&

.Previous Discussion...
Clear and dry over NorCal this evening as upper high centered west
of San Diego influences the weather. No delta breeze this evening
and temperatures are similar to 24 hours ago. Forecast is on track
and no evening update will be needed.
.Discussion...
A trough of low pressure is moving into the Pacific Northwest
while remnants of high clouds from what is left of Marie is
continues moving south and east of the area today. Some smoke from
the wildfires has made it into the Northwestern portions of Shasta
county today and will likely decrease some this evening but
increase again late tonight and Sunday morning as northerly winds
develop.

The trough will move east for Sunday and temperatures will
gradually warm through Monday with Monday looking like it will be
the warmest day with highs 95 to around 102 in the central
valley. The warmer temperatures will be over the north end of the
valley. Light northerly flow can be expected during the daytime
for Sunday and Monday.

By the middle of next week a trough of low pressure will reform
along the west coast to bring a cooling trend to the interior. No
rain or any hints of rain is in the forecast the next week.


.Extended Discussion (Wednesday through Saturday)

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.
