area forecast discussion
national weather service sacramento ca
343 am pdt Sat jun 24 2017

Synopsis
Hot again today except for significant cooling in the delta and
delta influenced areas of the southern half of the sacramento
valley, and northern san joaquin valley. More significant cooling
for the remainder of interior norcal expected Sunday into early
next week. Isolated afternoon evening thunderstorms possible over
the mountains through Sunday.

Discussion
Upper level ridge axis will center over the west coast today
bringing continued hot temperatures this afternoon over the
northern half of the cwa. The southern CWA will continue to see
cooling today thanks to a significant delta breeze expected to
continue through the day. The hottest temperatures today will be
in the northern sacramento valley where temperatures reaching 110
degrees are forecast. This area is actually seeing temperatures
somewhat cooler this morning thanks to lighter north winds which
has reduced the adiabatic warming affect. The delta influenced
areas are seeing a few to several degrees of cooling this morning
as well. Satellite fog product shows some coastal stratus making
its way into the delta this morning so early morning cloudiness
will likely impact western solano county. Southerly flow aloft and
instability will bring another threat of afternoon thunderstorms
over the northern sierra today. Some instability over the coast
range may bring a threat of isolated thunderstorms today there as
well.

Upper ridge axis finally shifts inland on Sunday with main effect
being a significant cooling. All areas of the CWA should see
enough cooling to finally drop all heat products for the first
time in nearly a week. Coastal stratus is likely to intrude again
into the delta morning hours while southerly flow and instability
will bring another threat of afternoon thunderstorms over the
crests of the sierra and coast range. Weak upper troughing moves
over the west coast on Monday bringing still more cooling to all
areas. At this time it appears any shower activity associated
with this weak upper trough will remain north of the forecast
area. Little change in temperatures expected on Tuesday as weak
upper troughing lingers over the west coast. Stable westerly flow
should keep the entire CWA under fair skies.

.Extended discussion (Wednesday through Saturday)
trough will shift off to the east on Wednesday with the area
sandwiched between the trough to the east and high pressure to the
west for Thursday into Friday. Dry weather expected with plenty of
sunshine. Onshore flow will keep the delta breeze going. Rather
similar temperatures expected through Friday with high
temperatures within a few degrees of normal. Ridging starts to
build back in for next weekend, with a slight warming trend. Dry
weather expected with plenty of sunshine. Ceo

Aviation
Vfr conditions expected at the TAF sites the next 24 hours.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
