area forecast discussion
national weather service sacramento ca
321 am pdt Tue jul 23 2019

Synopsis
Hot temperatures this week with widespread temperatures near 100
degrees. There is a slight chance of thunderstorms over the
central sierra late this week, though they will likely remain east
and south of our forecast area.

Discussion
Clear skies cover most of interior norcal early this morning,
though satellite imagery shows another batch of mid and high
clouds moving north from central california ahead of another vort
moving up in the southerly flow. Current temperatures are in the
upper 40s and 50s in the mountain valleys, and in the 60s and 70s
across the central valley (coolest near the delta).

Hot weather will continue across the region through the remainder
of the week as high pressure over the desert southwest gradually
extends north and west. Highs today will be similar to Monday's
readings, though temperatures may be down a bit in the areas
influenced by the delta breeze as a short-wave moving through the
pacnw induces stronger onshore flow.

Highs through much of the central valley on Wednesday thru Friday
are forecast to range from 100-105 with delta breeze influenced
areas expected to be a bit cooler Thursday and Friday as the
breeze returns. Overnight lows will be mainly in the 60s to lower
70s helping to mitigate widespread heat impacts.

Axis of deeper moisture and instability is expected to remain
mostly to the south and east of the area through the remainder of
the week, though a few late-day thunderstorms may approach the
southeast corner of the forecast area on Thursday.

Extended discussion (Saturday through Tuesday)
High pressure ridging shifts over the west coast going into the
weekend Saturday bringing a little warming most areas. Subsidence
under the ridge should mean minimal convection. Mainly clear skies
are in store with just a little bit of warming from earlier in
the week. During this climatological warmest period of the year,
highs Saturday are forecast to be several degrees above normal but
still several degrees below record territory. Little change is
expected Sunday with just a bit more warming as the ridging
amplifies. Forecast models shift the upper ridge eastward on
Monday as a weak trough develops over the western pacific. This
will bring a little cooling while stable southwest flow aloft
keeps any precipitation out of the forecast. Still more cooling is
expected next Tuesday as the upper trough digs in along the coast
with daytime highs back down to near normal at the end of the
extended period.

Aviation
Vfr conditions next 24 hours. Local southwest wind gusts 20-25
kts near ksuu, otherwise sustained winds less than 15 kts.

Sto watches warnings advisories None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
