Area Forecast Discussion
National Weather Service Sacramento CA
332 AM PDT FRI JUN 24 2016

.SYNOPSIS...
Locally breezy north winds today and Saturday for increased fire
danger mainly Sacramento valley. Near normal temperatures today
then well above normal temperatures and dry conditions Saturday
through the middle of next week.

&&

.DISCUSSION...
Upper level low now over the Pacific Northwest will be shifting
eastward into the northern Great Basin today. Conditions this
morning are similar to 24 hours ago and should see similar high
temperatures today compared to Thursday. Change in todays pattern
will be in the winds which will be turning northward today as
surface high pressure pushes into the Pacific Northwest. These
drying north winds will bring down humidity values today which
combined with the winds will bring increased fire danger
especially in the northern Sacramento valley. Tightest northerly
gradient forecast to occur overnight tonight when Medford to
Sacramento gradient may top 10 mb. With westerly winds aloft upper
level support is lacking so expect breezy winds to be fairly
localized. Upper ridging builds over the west on Saturday bringing
a significant warm up as the breezy north winds decrease. High
pressure over the western U.S will bring continued very warm
temperatures Sunday and Monday with highs expected to continue around
10 degrees above normal.

&&
.EXTENDED DISCUSSION (Tuesday THROUGH Friday)

High pressure will remain in control through midweek as trough
remains just off the coast. Daytime highs will range 5-14 degrees
above normal. Expect dry conditions with temperatures in the upper
90s to 105 across the Valley, and 70s-90s over foothills and
mountains. Tuesday and Wednesday will be the warmest days of the
period. Slight cooling trend starts Thursday with valley highs
back in the 90s by Friday.


&&

.AVIATION...

VFR conditions next 24 hours. Winds early this morning will be
light around 5-10 kts except for occasional gusts up to 25 knots
near the Delta region. Winds at TAF sites will increase after 18z
Friday with sustained winds around 10 kts and occasional gusts of
15-20kts. Winds will lessen after 01z Saturday.
