seasonal normal temperatures and minor HeatRisk by Friday.

.SHORT TERM...
(Today and tonight)
Issued at 203 AM PDT Wed Apr 2 2025

KMUX continues to show isolated rain and snow showers, primarily
across the Central Coast. This activity will continue to diminish
over the next few hours as the responsible surface low pressure
system continues to drift southeastward. While today will begin the
warming and drying trend, it may not necessarily feel like it with
the 00Z OAK sounding showing a -0.75 degrees Celsius temperature at
850 millibars, this is below the 10th percentile for April 2nd. San
Francisco Downtown (SFOC1) is actually forecast to come within two
degrees of their daily record low for today (this morning), the
official forecast is 45 degrees and the current record is 43 degrees
in 1955. Records or not, cold conditions can be expected in the
higher terrain as skies clear and winds diminish, promoting maximal
radiational cooling. Dry conditions and temperatures several degrees
below normal are on tap for today.

.LONG TERM...
(Thursday through Tuesday)
Issued at 203 AM PDT Wed Apr 2 2025

Warming trend continues Thursday, but widespread below normal
temperatures and cold conditions in the higher terrain continue to
be expected. Three climate sites daily low temperatures will be in
jeopardy Thursday morning: San Rafael (SARC1) forecast is 41 degrees
with a previous record of 39 degrees in 2010, San Francisco Downtown
(SFOC1) forecast is 44 degrees with a previous record of 41 degrees
in 2001, and Oakland Museum (OAMC1) forecast is 44 degrees with a
previous record of 43 degrees in 2003. Friday is when the sensible
weather will feel noticeably warmer with the return of above
seasonal normal temperatures and even minor HeatRisk. Global
ensemble clusters are in excellent agreement through Saturday with
an upper-level longwave ridge building into the West from the
Eastern Pacific Ocean. A cold front will try and dampen the warming
and drying party, but it`s impacts are largely only expected to be a
brief pause in the warming trend and rainfall totals of only a few
hundredths in the North Bay. Warming and drying trend resumes
Tuesday with the Climate Prediction Center indicating a 60-70%
probability that temperatures will be above normal April 7th-11th.

.AVIATION...
(12Z TAFS)
Issued at 426 AM PDT Wed Apr 2 2025

Showers have ended and winds have diminished. For the most part
VFR conditions this AM, but some post-frontal cumulus clouds
around 3-4k may at times impact terminals. KSJC seems to be the
mostly likely impacted with some stratus as Santa Clara valley
fills in. Winds will increase again this afternoon, but remain
out of the NW. Overall confidence is moderate to high.



Vicinity of SFO...VFR with breezy onshore flow.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Gradual improvement through 14-16Z with
VFR this afternoon. Lower confidence of evening cigs for KMRY.
Current taf shows VFR, but some guidance hints at bringing shallow
cigs back by 04Z.

.MARINE...
(Today through Monday)
Issued at 426 AM PDT Wed Apr 2 2025

Building high pressure offshore will lead to breezy northerly
flow over the coastal waters through early Thursday. Winds will
be strongest north of Point Reyes. The sea state will gradually
improve after Thursday as swell and wind decrease.
