Area Forecast Discussion

349 PM PDT WED JUN 29 2016


.SYNOPSIS...
Hot and mainly dry weather this week. Isolated late day
thunderstorms possible over the mountains.

&&

.DISCUSSION...
High pressure continues to be the predominant weather pattern across
interior northern California. Temperatures, as of this afternoon,
are running a few degrees cooler compared to 24 hours ago. Delta
breeze should bring some cooling overnight, with lows in the mid
50s in the Delta, and upper 50s to low 60s near the Sacramento
area. Light easterly flow overnight may drift smoke from the
Trailhead fire down into the Auburn area.

Cooling trend is expected late this week, as an upper trough
develops along the Pacific Northwest. Saturday`s highs should be
around the mid 90s in the Valley, except for a few triple digits
in the northern Sacramento Valley. Model guidance suggest
monsoonal moisture making its way northward along the Sierra crest
late this week. Isolated storms may be possible mainly south of
Lake Tahoe and east of the Sierra crest. A few late day afternoon
thunderstorms may be possible along the Coastal Range late this
week, as some instability might be present.

&&
.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)


A weak upper trough will persist over the Pacific Northwest over
the weekend into early next week with subtle cyclonic flow over
NorCal, resulting in dry weather and near normal temperatures.
Expect high temperatures in the 90s across the Valley, with 70s
and 80s over the mountains.
