New UPDATE, MARINE

SYNOPSIS
Issued at 1202 AM PDT Mon Apr 29 2024

High pressure brings quiet weather and slowly warming temperatures this week. Breezy onshore winds will keep temperatures along the coast cooler however. Cooler and more unsettled conditions return for next weekend into next week with light rain chances in the forecast.

UPDATE
Issued at 950 AM PDT Mon Apr 29 2024

Quite a different scene as compared to the last few mornings as skies are currently clear across the region. Clear skies will allow for temperatures to reach the upper 50s on the beaches and the mid 70s in the warmest inland valley locations. Strong northwesterly winds will continue today with most locations likely to receive gusts of 25 mph, especially along the immediate coastline and higher peaks. These strong northwesterly winds are also resulting in poor marine conditions.

No update needed...

SHORT TERM
(Today and tonight)
Issued at 1202 AM PDT Mon Apr 29 2024

A relatively benign weather pattern persists featuring quasi-zonal flow across California with weak troughing across the Pacific Northwest states. This will bring a weak/dissipating cold front through the Bay Area with little fanfare, as the primary weather concern remains steady onshore winds. Conditions will be rather breezy along the coast yet again, with peak gusts in the 30-40 mph range. This will have a cooling effect on temperatures there, while inland readings warm during the afternoon. High temperatures will range from the upper 50s on the beaches to the mid 70s in the warmest inland valleys. Look for patchy coastal stratus development once again overnight with lows in the 40s.

LONG TERM
(Tuesday through Sunday)
Issued at 1202 AM PDT Mon Apr 29 2024

A subtle ridge over California continues through the work week, with an upper level low passing through the Great Basin. The story of the week will be clear skies and warmer weather with interior valleys seeing highs in the low 80s and the coasts seeing highs in the mid 60s to lower 70s.

The upcoming weekend sees a pattern change with an upper level low coming into the Pacific Northwest on Friday, bringing a weak front through California. The chance of rain on Saturday and Sunday, currently up to 20-30% Probability of Precipitation, has expanded throughout the forecast region, although rain amounts remain light with the higher elevations receiving up to a tenth of an inch of rain. Cluster and ensemble model output also suggest a deeper upper level low coming into the Pacific Northwest during the first week of May, and CPC products continue to suggest cooler temperatures and increased rain chances into the second week of May.

AVIATION
(12Z TAFS)
Issued at 432 AM PDT Mon Apr 29 2024

Patches of MVFR stratus across the higher elevations of the Bay Area and Central Coast, impacting the Monterey Bay terminals at some point this morning and generally staying away from the Bay Area terminals. Moderate to breezy onshore winds building again this afternoon, gusting to 20 to 30 knots. Not expecting widespread stratus coverage to return this evening into Tuesday morning.

Vicinity of SFO... VFR through the TAF period. Breezy to gusty west- northwest winds will return this afternoon. Model output showing gusts up to 30-35 knots through the evening, but would not be surprised to see gusts exceeding 35 knots develop.

SFO Bridge Approach... Similar to SFO.

Monterey Bay Terminals... Patchy MVFR stratus expected to impact the terminals at some point this morning. Moderate onshore flow will build in the afternoon with gusts up to 20-25 knots. Low confidence of stratus returning to the region this evening through Tuesday morning.

MARINE
(Today through Saturday)
Issued at 950 AM PDT Mon Apr 29 2024

Hazardous conditions will prevail over the coastal waters through midweek thanks to persistent gusty northerly winds. Gale force winds with gusts 40 to 45 knots will be possible over the outer waters and portions of the immediate coast near Point Reyes and Point Sur. The strong winds will result in fresh steep wind waves with heights reaching 10 to 12 feet. Conditions will gradually improve late in the week into next week.
