Area Forecast Discussion
National Weather Service Sacramento CA
230 AM PDT Tue Apr 16 2024
.Synopsis...
Dry and milder weather through the week.
&&
.Discussion...
Other than some lingering low clouds over the Motherlode, skies
are clear early this morning. Current temperatures are a little
milder compared to 24 hours ago and generally range from the 30s
and 40s in the mountains to the lower to mid 50s across the
Central Valley. Humidity is high in the valley from about the
Sacramento area southward, and there may be some patchy fog early
this morning.
Upper level ridging from the eastern Pacific will dominate the
synoptic pattern this week. Occasional high clouds will be
possible with systems passing well to the north of the region.
High temperatures will gradually rise as we progress through the
work week. Temperatures today will be in the mid 70s to lower 80s
for the Valley, then Wednesday and Thursday we should see more
widespread readings in the lower 80s across most of the Valley.
Breezy northerly winds may develop Wednesday morning in wake of a
short-wave moving through the PacNW. Best chances for gusty
northerly winds of 15-25 mph will be along the I-5 corridor from
Sacramento northward.
&&
.EXTENDED DISCUSSION (Saturday THROUGH Tuesday)...
Ensembles and clusters depict an upper level ridging pattern over
much of the extended forecast period, although there is some
uncertainty in the clusters early next week. This pattern will
result in dry conditions and above normal temperatures (generally
5-10 degrees above climatology). The NBM indicates daytime high
temperatures generally in the upper 70s to low 80s for the Valley
through Monday, with upper 60s to 70s in the foothills, and mid
50s to 70s in the mountains. Slight cooling might be expected on
Tuesday, with Valley highs in the mid to upper 70s.

.AVIATION...
VFR conditions prevail next 24 hours except local MVFR possible
in the Central Valley and Motherlode thru 15Z. Surface wind gusts
below 12 knots.
