Area Forecast Discussion
National Weather Service Sacramento CA
230 AM PDT Sun May 12 2024
.SYNOPSIS...
Warm weather will result in areas of moderate heat most of the
week ahead. Dry and occasionally breezy conditions look to
accompany this warm stretch as well.
&&
.DISCUSSION(Through Tuesday)...
Skies are clear early this morning. IR difference imagery shows
stratus has returned to the entire coast, but profiler data
indicate the depth of the marine layer is only around 1.5k ft.
Nevertheless, it's enough to allow a Delta Breeze to develop as
surface pressure gradients trend toward onshore. The valley may
see minor cooling of a few degrees the next couple of days as a
weak trough passes.
Beginning Tuesday, warming returns as ridging from the eastern
Pacific builds in reducing onshore flow and bringing another
period of north winds in the valley. Portions of the central and
northern Sacramento Valley will have a chance of seeing their
first triple digit heat of the season during the middle of the
week, but heat risk will likely remain in the moderate category.
Enough moisture and instability is expected to be present over the
northern Sierra for a few afternoon showers and thunderstorms on
Monday and Tuesday, otherwise dry weather will continue.
&&
.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...
EPAC upper ridge extends inland over interior NorCal Thursday.
Ridge flattens Friday into Saturday as short wave troughs drops
into the PacNW. At same time, cut off low west of CA approaches
over the weekend and pushes inland Monday, however models differ
with progression rate. Low could spark an afternoon shower or
thunderstorm over higher elevations of Sierra Nevada Sunday and
Monday. Cooling trend expected through the extended forecast
period, but high temperatures remain above normal through the
weekend.
&&
.AVIATION...
VFR conditions over interior NorCal next 24 hrs. Sfc wind mainly
below 12 kts except vcnty of Delta SWly sfc wind up to 20 kts
possible.

.STO WATCHES/WARNINGS/ADVISORIES...None.
