Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Sacramento California
910 PM PDT Wed Jul 9 2014
a few showers or thunderstorms will be possible over some mountain
areas over the next couple of days. Otherwise mainly fair skies
are expected through the early next week with near normal
the thunderstorm activity to the north of our area has died down
this evening. Some fire starts were reported from the lightning
strikes. Marine layer is around 1500 feet this evening and a moderate
Delta breeze is flowing through the Delta. Temperatures are
running a couple of degrees cooler this evening. Temperatures
overnight will drop into the upper 50s to mid 60s for most areas
in the valley to mainly the 50s and 60s for the mountains.
A weak low to the west of the central California coast may help
to bring some monsoonal moisture northward along the crest on
Thursday and Thursday night. The low lifts northward Thursday
night and may be able to trigger some overnight showers and
thunderstorms...mainly near the crest and points eastward as well
as over the northern plateau area. Some activity may continue
Friday morning over the northern mountains. The low continues to project
the low will move far enough to the north during the day on Friday
to bring more stable air into most the region to end the treat of
showers and thunderstorms. The only exception would be the far
northern sections of California.
Saturday will be dry and slightly warmer. A decent Delta breeze
looks to continue late in the day and at night.
Extended discussion (sunday through wednesday)
High pressure dominates for fair skies through the extended period
with daytime highs warming slightly through midweek to a few to
several degrees above normal. Mid-level monsoonal moisture may
spread into the area late Tuesday and Wednesday...but instability
is progged to be weak at this time and will not add any
General VFR conditions expected to continue for the next 24 hours.
Winds across the valley south to west 5-15 kt. Near the Delta...SW
winds 15-30 kt will continue.
