...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 127 PM PDT Mon Apr 15 2024

Dry conditions are here to stay with a gradual warming trend through
midweek, peaking on Wednesday and/or Thursday. Onshore flow
increases toward the end of the week; cooling temperatures near the
coast as marine stratus returns.

&&

.SHORT TERM...
(This evening through Tuesday)
Issued at 127 PM PDT Mon Apr 15 2024

A gradual warming trend will kick off today with temperatures in the
mid-to-upper 50s near the coast and upper 60s inland. Low clouds
and/or fog make a return tonight, most likely across the North Bay,
with slightly warmer temperatures. Still, overnight lows will drop
into the mid 40s for most locations.

By Tuesday the warming trend will continue with afternoon highs
expected to range from the 60s to lower 70s near the coast with mid-
to-upper 70s inland. Dry conditions will also continue throughout
the forecast period.

&&

.LONG TERM...
(Tuesday night through Sunday)
Issued at 216 AM PDT Mon Apr 15 2024

Looking ahead to mid-week, warmer, drier weather reigns as ridging
builds in from the west. A warming trend will begin mid-week with
Wednesday and Thursday looking to be the warmest days. Inland highs
will reach the mid to upper 70`s and a few locations may reach the
low 80`s. Moving into Friday temperatures will cool down slightly to
the upper 60`s to mid 70`s as upper level ridging becomes more zonal
and allows for increased onshore flow.

High pressure will keep precipitation pushed northward of the Bay
Area with the CPC highlighting below average precipitation for next
6-10 days. Ensemble guidance indicates that unsettled weather may
return towards the end of April but as of now confidence remains
low.
