New SYNOPSIS, SHORT TERM

SYNOPSIS
Issued at 1227 AM PDT Sun Apr 28 2024

High pressure brings quiet weather and slowly warming temperatures this week. Breezy onshore winds will keep temperatures along the coast cooler however.

SHORT TERM
(Today and tonight)
Issued at 1227 AM PDT Sun Apr 28 2024

High pressure will remain offshore as a weak cold front slowly dissipates across the Bay Area today. The pressure gradient will remain relatively robust, thus supporting breezy northerly winds today particularly over the local waters and along the coast. Patches of stratus will again develop within marine influenced areas before mixing out during the late morning to early afternoon hours. High temperatures will range from around 60 on the beaches to the mid 70s for the warmest portions of interior Monterey County and for areas bordering the Sacramento Valley. Lows tonight will dip into the 40s with mostly clear skies away from the coast.

LONG TERM
(Sunday night through next Saturday)
Issued at 245 PM PDT Sat Apr 27 2024

Longwave pattern shows more zonal flow setting up through at least midweek. Zonal flow aloft will keep more of the same: subtle warming (inland areas), dry conditions, patchy night and morning stratus, and breezy onshore flow. Speaking of winds, probabilistic guidance really highlights northerly winds over the coastal waters Monday and Tuesday. Current forecast has trended upward with regards to winds as well. Still not strong enough for a wind advisory for the coast, but gusts of 40mph plus will possible.
Probably not the best beach days for Monday/Tuesday. Elsewhere away from the coast there is a high likelihood (greater than 70%)
of seeing gusts over 25 mph.

The second half of the work week will feature additional warming with far interior location eclipsing 80 degrees. Still breezy out of the NW so temperatures will hold mostly steady along the coast and bays. The warm up and breezy NW flow finally ease next weekend as the zonal flow becomes more amplified with approaching upper trough.

AVIATION
(06Z TAFS)
Issued at 1030 PM PDT Sat Apr 27 2024

Patchy stratus across the higher elevations of the East Bay, San Mateo Peninsula, and northern Monterey County. Stratus coverage is expected to expand through the night, with MVFR ceilings expected to spill over into the Santa Clara Valley and the Monterey Bay region.
Light to moderate northwest flow overnight, building through the day on Sunday with gusts up to 20 to 30 knots.

Vicinity of SFO... Low confidence (up to 10% probability) of MVFR ceilings early Sunday morning. Breezy west-northwest winds will build through Sunday with gusts up to 35 knots, around a 10-20% probability of gusts over 35 knots on Sunday afternoon and evening.

SFO Bridge Approach... Similar to SFO.

Monterey Bay Terminals... MVFR ceilings developing overnight as patchy stratus expands. Stratus clears out Sunday morning as breezy onshore flow develops, gusting to 20 knots. Winds diminish on Sunday evening, with most stratus development coming after the end of the TAF period.

MARINE
(Tonight through next Friday)
Issued at 1030 PM PDT Sat Apr 27 2024

Strong northwesterly winds to will persist through the weekend posing hazardous conditions for small crafts.
