AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
236 PM PDT Sat Apr 25 2015

.Synopsis...
A fast moving wet system pushes out of the area today with
scattered showers continuing across the mountains through this evening.
High pressure brings dry conditions Sunday through mid week next
week. Warmest temperatures Monday with slight cooling trend
through the end of the week.

&&

.Discussion...
Some showers are continuing at this time over the foothills and
mountains. Showers are expected to continue into the evening
hours before ending. In general most valley areas will continue to
remain dry through the afternoon and evening but there is a
slight chance for a few showers in the valley along the east side.

High pressure will build over the region Sunday into Monday to
bring dry and warming temperatures to the region. Northerly winds
will persist the next few days but nothing of significant strength
to cause any concern. The warmest temperatures will occur on
Monday and Tuesday of this coming week. Temperatures will be
warming into the mid to upper 70s in the valley for Sunday with
continued warming into the 80s for Monday and Tuesday. Monday and
Tuesday will have temperatures 10 to 15 degrees above seasonal
normal`s.

.Extended Discussion (Wednesday through Saturday)

Warm weather should continue into at least Wednesday as the upper
level ridge shifts eastward. A trough will approach the West Coast
next Thursday...which should bring at least some cooling to
Northern California. Both the GFS or ECMWF forecast this system to
be rather moisture-starved, so we`ve kept only slight chance
wording across far NorCal. A weak trough remains over California
through the end of next week. No precipitation is expected, and
slightly warmer than normal temperatures should continue.

Weather system is now exiting Northern California. Primarily VFR
conditions and light winds are expected the next 24 hours across
Valley TAF sites. Over the mountains, scattered IFR/LIFR showers

Snow levels remain between 6000-7000 feet.
