Area Forecast Discussion
National Weather Service Sacramento CA
207 PM PDT Wed Jul 19 2017


.SYNOPSIS...
Warm and dry through the week. Locally breezy winds possible the
next several days. Hot temperatures return for the weekend.

&&

.DISCUSSION...

Weak trough passing across the Pacific northwest has brought dry
southwest flow aloft and a return to near normal temperatures
across northern California. Temperatures ranged from 94 at Redding
to 72 at Blue Canyon as of the early afternoon. Although
conditions were dry with very little cloud cover, smoke from the
Detwiler fire was streaming across the foothills and Sierra south
of Highway 50.

As trough across the Pacific northwest continues to slide
northeastward, southwest flow aloft will remain with subtle rising
heights as upper level high pressure continues to dominate the
forecast. As a result, warm and dry conditions will continue
across the forecast area through the end of the week and into the
weekend with little cloud cover. Temperatures will gradually warm
up again heading into the weekend with temperatures between 5 and
10 degrees above normal.

&&

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)

Upper low off the NW CA coast Sunday weakens and gradually drifts
inland across northern portions of the state early next. Main
impact will be a slow cooling trend into midweek with a slight
chance of an isolated afternoon thunderstorm over the higher
terrain Sun/Mon.
