AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
346 AM PDT Mon Jul 28 2014

.Synopsis...
Monsoonal surge of clouds will bring a few thunderstorms and
showers to portions of interior NorCal into mid-week. The increase
in clouds and return of the Delta Breeze will result in a little
cooler temps for portions of the Central Valley today.

&&

.Discussion...
Mostly clear skies across the interior of NorCal early this
morning except for some high clouds along the eastern edge of the
forecast area. Temperatures are once again mild, mainly in the 60s
and 70s across the region early this morning.

Satellite imagery shows mid and upper-level moisture beginning to
move back toward NorCal after retreating somewhat late Sunday and
overnight. WV imagery shows a large well-defined wave over
northern Baja that is forecast to move up into the vicinity of
Lake Tahoe tonight. Thunderstorms are once again developing over
SoCal and offshore early this morning, and appears this feature
may provide enough lift to generate some showers and even a few
thunderstorms continuing overnight tonight as it approaches. By
later Tuesday, looks like convective activity will mainly return
to its normal diurnal cycle over the mountains.

Temperatures will remain hot through the upcoming week as the
strong ridge persists over the western US. There will be minor day
to day fluctuations based on the depth of the marine layer and
strength of onshore flow and cloud cover, but the main theme will
remain hot.

&&

.Aviation...
Mainly VFR next 24 hours. Winds generally 10kts with local gusts
15-20 kts across valley, and sustained 15 to 25 kts poss through
Delta. Isolated showers/thunderstorms over Sierra this afternoon,
with slight chance moving into foothills and southern Sac/northern
San Joaquin valley after 00Z Tue.

&&

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