AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
229 PM PDT Wed Oct 1 2014

.Synopsis...
Dry and warmer weather this week as high pressure rebuilds. Breezy
to locally windy northerly winds today, decreasing Thursday.

&&

.Discussion...
North winds continue to be pretty breezy along the valley and
western slope of the Sierra today. Winds have been gusting to
around 30-35 mph along the western side of the Sac Valley and
peaking around 40-50 mph in local areas along the Sierra and
favorable SW-NE canyons. N-S surface pressure gradients are
slackening some and becoming more easterly since this morning.
As a result, breezy north winds should continue to slowly decline
through the evening...while breezy east-northeast winds over the
mountains are expected through tomorrow morning.

Temperatures are running several degrees warmer today as strong
high pressure builds into the region. The warming trend will
continue through at least Saturday, with temperatures rising
several degrees above normal and Saturday being the hottest day
of the week. However, records are not expected to be broken during
this stretch of summer-like weather. Though winds will be lighter
than they were today, dry north winds will continue through the
early weekend with occasional breeziness. Shen

.Extended Discussion (Sunday through Wednesday)

Medium range models similar in showing strong upper level ridging
over Interior NorCal Sunday gradually weakening through the
extended forecast period. Also, weak upper low forecast to develop
early next week and slowly approach the Coast. Result will be dry
weather with high temperatures initially about 10 degrees above
normal on Sunday, returning to near normal by the middle of next
week. EPAC surface high pressure extends through the PacNW into
the Great Basin with thermal troughing resulting in continued
locally breezy North to East wind Sunday into Monday morning.
