Area Forecast Discussion
National Weather Service Sacramento CA
328 AM PDT Tue May 30 2017

Cooler today and Wednesday. A weak system will move through the
interior late tonight and Wednesday morning to bring light
amounts of rain. Dry and warmer for the remainder of the week.


.Discussion...(Today through Friday)
A weak trough remains over the area today and we may continue to
see some afternoon thunderstorms along the crest south of Alpine
County this afternoon. A broader trough in the Pacific with more
moisture will move through from late evening through mainly
Wednesday morning. Light amounts of rain are expected for the
valley with accumulating amounts less than a tenth of an inch for
most areas. Some showers may linger Wednesday afternoon in the
foothills and mountains before ending. Cooling all areas will
occur both today and Wednesday with the coolest day of the week
likely to occur on Wednesday.

Thursday and Friday the region will be under a dry zonal flow
pattern and temperatures will warm back to normal or slightly
above normal for the interior.


A weak shortwave moves through Saturday with a broader trough
developing and lingering over the region through Tuesday. The
models are showing the trough is lacking enough moisture to
produce any activity over the interior. Temperatures will warm a
little above normal for this time of year but remain pleasant.



VFR conditions expected through the next 24 hours for TAF sites.
Winds generally 10 kts or less, increasing up to 10 to 15 kt with
gusts up to 20 kt after 23z in the southern Sacramento valley and
northern San Joaquin valley. Gusts to around 30 knots in vicinity
of the Delta through 06z.
