AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
840 AM PDT Fri Mar 27 2015

.Synopsis...
Mainly warm and dry weather will continue into next week for the
majority of the area. Weak systems may bring a few showers to the
mountains this weekend into early next week.

&&

.Discussion...
No changes expected for today`s forecast. Upper level ridge axis
will continue to shift east as trough approaches from offshroe.
Most of the area will see sunny skies and near record or record
high temperatures today. A few showers may move into Shasta County by
the late evening hours but any accumulations will be scattered and
light. CEO

.Previous Discussion...
High pressure continues to dominate over California early this
morning. Satellite imagery shows that the upper level ridge axis
has shifted east into the Great Basin as a trough approaches the
West Coast.

For today, skies will remain mostly clear across the forecast
area, though we should begin to see increasing clouds from the
northwest in the afternoon and evening. With the approaching
front, we may begin to see a modest Delta Breeze develop in the
mid to late afternoon timeframe, but this shouldn`t significantly
impact today`s highs. Highs are still expected to reach the lower
to mid 80s across the Valley today, with 60s and 70s over the
mountains. Several daily high temperatures records will likely be
broken. Today`s records are 79 at Sac Exec, 82 at Stockton, 83 at
Red Bluff and Redding, and 85 at Modesto and downtown Sac.

We`ll see a bit more cooling on Saturday as the trough slowly
moves through the region. A few showers will be possible Friday
night into early Sat along the Shasta County mountains, and
Saturday and Sunday afternoons along the Sierra south of Tahoe.
Temperatures will remain well above normal through the rest of the
weekend into early next week.

.Extended Discussion (Tuesday through Friday)

Dry weather with daytime highs ranging 5-10 degrees above normal
expected for the extended forecast. A weak trough will move into the
Pacific NW by early Tuesday morning and brush far NorCal which
will lower daytime highs compared to Monday`s highs. Only a slight
variation to temperatures Wednesday into Friday. Valley highs will
generally be mid 70s to near 80. For higher terrain, expect mid
50s near the Sierra Crest to the low 70s in the foothills. JBB

.Aviation...

VFR conditions will continue today. Surface winds in the Central
Valley will generally be less than 10 kts for much of today. However,
a weak delta breeze is expected to develop late afternoon which
may slightly enhance winds in the delta region into Stockton and
the Sac Metro region between aft 00z.

.STO Watches/Warnings/Advisories...
None.
