Area Forecast Discussion
National Weather Service Sacramento CA
230 AM PDT Fri Apr 19 2024

.Synopsis...
Warm and dry weather continues into early next week. Locally
breezy at times.

&&

.Discussion...
A batch of high clouds is moving across NorCal early this morning
as the upper ridge has weakened slightly by a passing short-wave
trough. Offshore surface pressure gradient has weakened and
transitioned to weak onshore and profiler data indicate the marine
layer has returned to the coast with a depth of 1.5-2k ft. This
may bring some minor cooling to the Delta and south valley today,
but otherwise little change from Thursday is expected. Shower
chances are expected to remain further south in the Sierra closer
to the vort center currently approaching the coast near Vandenberg.

Ridge rebounds over the weekend and into early next week with
highs expected to be well above-average (10-15 degrees),
especially Sunday and Monday when warmest temperatures will be in
the mid to upper 80s through the Central Valley with an outside
chance for the first 90 degree readings of the season.

&&

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)...
Dry weather expected Tuesday under weak upper level ridging, then
short wave trough progged to deepen over the CWA Wednesday into
Friday. This will result in a threat of precip mainly over the
northern and eastern foothills and mountains and Northern Sac
Valley. Storm total QPF looks to be light with minimal impacts to
mountain travel. Above normal high temperatures forecast Tuesday,
then near to slightly below normal through the remainder of the
week.

&&

VFR conditions over interior NorCal next 24 hrs. Sfc wind mainly
below 12 kts except vcnty of Delta SWly sustained wind up to 20
kts.
