Area Forecast Discussion
National Weather Service Sacramento CA
1002 PM PDT SAT JUL 30 2016

Temperatures cooling off this weekend into the first part of next
week to near seasonal normals.


Moderate delta breeze in progress this evening with temperatures
5 to 10 degrees cooler versus 24 hours ago many areas. Wind gusts
to 30 mph will continue over the delta. Current forecast is on
track no update will be needed.

.PREVIOUS DISCUSSION (Today through Sunday Night)...
Twenty four hour temperature trends are mixed at this hour. Some
stations are showing temperatures are running slightly warmer but
most are indicating temperatures are running slightly cooler. The
marine layer continues at around 1400 feet deep and we have decent
flow through the delta. The winds through the delta will be
stronger tonight and will help to bring cooler air into the valley
overnight. This will help to bring a cooling trend.

A trough of low pressure moving into the Pacific Northwest will
help to push the high pressure area south slightly to bring some
synoptic cooling to the region through Sunday. This will also
help to keep monsoonal moisture well to the south of our area. The
current low pressure area will be replace by another one on Monday
and Tuesday. Expect a cooler temperatures Sunday then little
change in temperatures the next couple days.

The San Joaquin Valley Air Pollution Control District is
continuing their Air Quality Alert for San Joaquin county and
southward into Monday.



Dry weather for the rest of next week. Region will be under the
influence of broad upper level troughing which will result in weak
onshore flow. Monsoon moisture looks to remain shunted far to the
south of the area. Wednesday will be the hottest day of the
period with daytime highs a few degrees above normal. Otherwise
expect seasonable temperatures for Thursday into the weekend.




VFR conditions the next 24 hours. Winds 5-15kts with gusts to 25 kts
near the Delta.
