AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
939 PM PDT Tue Jul 22 2014
After another below normal temperature day on Wednesday expect a
warming trend Thursday into the weekend.
.Short Term Discussion (Today through Friday)...
The interior has quited down this evening and the activity has
moved north into Oregon as the wave lifted north. Earlier
impressive rainfall rates where being observed with Doppler RADAR
and a report of some mud and rock slides with water on Highway 36
was reported by CAL-TRANS for the area warned.
Skies will remain clear overnight and a moderate delta breeze will
continue overnight to help cool valley temperatures mainly into
the low to mid 60s by morning. A few patches of stratus will
likely make it into the Sacramento area towards morning. The
marine layer is deep at around 3000 feet. Wednesday will be the
last of the recent string of below normal daytime highs for
the area. After a trough along the Pacific Northwest coast moves
through high pressure will begin to build Thursday and Friday to
warm temperatures. First to around normal for Thursday then above
normal for Friday. Winds will also become northerly for both days
but do not look that strong.
.Extended Discussion (Saturday through Tuesday)
High pressure ridge building in from the Desert Southwest will
result in above normal temperatures through the weekend and into
early next week. Portions of the Central Valley will likely be
reaching 100+ temperatures during this timeframe. There may be
enough onshore flow through the Delta to keep Delta Breeze-
influenced areas just below the triple-digit threshold.
Medium-range models continue to suggest monsoonal moisture
advecting northward. At this stage, a slight chance of
thunderstorms will be possible south of Tahoe on Sunday, with
perhaps a more widespread chance over the Sierra on Monday.
VFR conditions expected the next 24 hours. Near the Delta,
southwest winds 15 to 25 kt will be possible through Wed.
