area forecast discussion
national weather service sacramento ca
213 pm pdt Fri jul 19 2019

Synopsis
A gradual warming trend will be seen this weekend into next week.

There is a slight threat of afternoon thunderstorms over the
northern sierra crest Saturday and at the end of next week. Valley
temperatures may hit the triple digits by late week. Breezy winds
through the delta and over the sierra crest at times.

Discussion
Weak troughing over northern california continues today with high
temperatures the coolest of the period, expected to increase
gradually each day through early next week. A weak shortwave moves
across the area Saturday before the dominant ridge over the great
basin builds in for the remainder of the period. This shortwave
may produce an isolated storm or two over the sierra crest
Saturday evening, otherwise dry conditions continue across the
area. Ridging will allow temperatures to creep back up into the
mid and upper 90s by Monday, with some portions of the northern
sacramento valley seeing high temperatures up in the triple
digits.

Extended discussion (Tuesday through Friday)
No major changes to the forecast package this afternoon as
interior northern california will be sandwiched between an upper
trough pushing into the pacnw Tuesday and large 4 corners high.

The upper high will gradually expand westward through the
remainder of the extended period. This will result in near normal
high temperatures Tuesday slowly warming to about 3 to 7 degrees
above normal towards the end of the week. Monsoonal moisture flow
around upper high could lead to afternoon deep moist convection
over southern portions of the northern sierra nevada Thursday and
Friday.

Aviation
Vfr skc or a few cirrus and scattered cumulus over the mountains
during the daylight hours through 01z sun. Local MVFR ifr
conditions in marine stratus vcnty of carquinez strait delta from
06z-19z sat. Local swly 20g35kt vcnty of delta, otherwise winds
<15 kts.

Sto watches warnings advisories
None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
