Area Forecast Discussion
National Weather Service Sacramento CA
250 PM PDT Wed Aug 21 2019


.SYNOPSIS... 
Strengthening high pressure will result in dry weather with above
average temperatures into next week.

&&

.DISCUSSION...
The forecast remains on track this afternoon as a broad trough
passes to our north. As a result of that, northern California is
seeing high clouds over the region this afternoon; however,
temperatures are still forecast to rise this afternoon as onshore
flow weakens.

Once the trough passes through the region, building high pressure
will dominate the rest of the forecast period. Expect to see and 
feel above normal temperatures for most of the region through the 
weekend. Most areas will be 5-7 degrees warmer than usual during 
the day. 

&&
.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)...


For the extended period, our weather will continue to be
influenced by the upper level high which extends NW from the 
Desert SW over interior Northern California as E Pacific high 
extends inland. Above normal temperatures look to continue 
through Wednesday, with triple digit heat expected in the Northern
Sacramento Valley with upper 90s elsewhere in the Central Valley.

&&

.AVIATION...

VFR conditions the next 24 hours. Scattered to broken high clouds
into the overnight, otherwise mostly clear. Winds under 12 knots 
except for in the Delta. 
&&

.STO WATCHES/WARNINGS/ADVISORIES...
None.
