Area Forecast Discussion
National Weather Service Sacramento CA
210 PM PDT SUN JUL 24 2016

.SYNOPSIS...
After one day of cooling on Monday widespread triple digit heat
expected in the Central Valley. High temperatures well above
normal Tuesday through Friday. Cooler next weekend.

&&

.DISCUSSION...
The marine layer is at around 1000 feet deep and may increase
slightly this evening. The air flow has reverse direction today
but is still very light and inland areas will heat up to near
yesterday`s highs.

By late this evening and overnight the delta breeze looks to
become moderate to strong and there should be a decent amount of
stratus returning to the Bay Area. That should help to reduce
temperatures slightly for Monday for many areas.

Tuesday and Wednesday is when the high pressure from the
Southwest begins to build over our area and temperatures will
likely range from 103 to 111 degrees throughout the valley. The
hottest temperatures will be over the Northern Sacramento valley.
Wednesday`s records are not as high as Tuesday`s records so
temperatures could be nearing record heat that day.

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)

Strong high pressure will continue to dominate weather across the
region for the end of the work week. Heat looks to peak Thursday
with Valley highs in the range of 103-110 degrees, possibly as
hot as 111 in Redding! Temperatures a few degrees cooler for
Friday. Very dry conditions expected along with the heat which
will increase fire weather concerns, although winds will generally
be light under the ridge. Models continue to depict trough
developing off the West Coast on Friday and moving inland for the
weekend. This should serve to cool temperatures a bit for Saturday
and Sunday with increasing onshore flow. Daytime highs trending
back toward normal levels for next week. Trough may serve to draw
monsoonal moisture northward as well, although most model
solutions still keep it south of the local area. GFS pulls
moisture further north and paints some scattered convection across
the Sierra. Have kept with dry forecast for now until details can
be better resolved.
