August 10, 2016 – Another warm day is expected across interior NorCal. Highs today will be close to average for August. Dry weather with a gradual warmup through the rest of the week. Broad trough remains over the area today. Flow through the Delta has picked up early this morning and will continue today with the marine layer deepening to around 2K feet. This will result in a bit cooler temperatures as far inland as the Sacramento region. Elsewhere, highs today are expected to be very similar to Tuesday’s readings.
Warming trend picks up beginning Thursday and continuing into the weekend as high pressure strengthens and the marine layer is suppressed. Triple digit heat is expected to return to the North Valley Thursday, then spread south through most of the Central Valley by Saturday.

Dry weather continues through the extended period with monsoonal moisture remaining well to the south in the desert Southwest. Slight less hot weather is expected on Sunday as the ridge axis shifts eastward and a weak upper trough moves in. High temperatures look a little cooler than the widespread triple digits projected on Saturday for the Valley. Upper 90s are expected for most Valley locations, except reaching around 100 for the northern Sacramento Valley. Little change is expect early next week with a similar pattern of above normal temperatures but well below record heat.
