New SYNOPSIS, SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1256 PM PDT Mon Jun 3 2024

Temperatures remain at or slightly below seasonal averages today.
Tomorrow sees a dramatic warmup with a Heat Advisory in effect for the inland areas through Thursday. Temperatures will moderate towards the latter part of the week.

SHORT TERM
(This evening through Tuesday)
Issued at 1256 PM PDT Mon Jun 3 2024

The morning started pretty cloudy across the region as mid- to high level clouds stemming from a cold front coming through the Pacific Northwest came through the region. Several stations recorded coastal and orographically forced drizzle this morning, but accumulations topped out at a few hundredths of an inch. Current satellite imagery is showing breaks in the cloud cover as the high clouds move away, while as far as satellite imagery and observations show, lower clouds linger mainly along the coast of western San Mateo County and scattered throughout the coastal ranges. Breezy northwest winds will continue today with winds gusting to 20 to 30 miles per hour at the gaps and passes. Temperatures remain at or slightly below seasonal averages, with highs ranging from the upper 50s to low 60s along the coast, to the mid 60s to lower 70s at the Bayshore, and the mid 70s to lower 80s in the inland valleys. Low temperatures will hover between the low to mid 50s, with the upper 50s expected in the inland portions of the North and East Bays.

Tuesday sees a pattern change as a ridge building in the eastern pacific impacts our state. High temperatures will warm quite dramatically with 10-20 degree increases expected across the region.
High temperatures on Tuesday will range from the mid 60s to lower 70s at the immediate coast, to the upper 70s to mid 80s along the Bayshore, and in the 90s for the inland valleys with the warmest locations reaching 100. A Heat Advisory comes into effect Tuesday for the inland North Bay and East Bay, extending into Thursday.
Moderate HeatRisk (corresponding to a risk for heat-related illnesses for sensitive populations, such as children, the elderly, pregnant women, the ill, or those working outdoors) is expected for most of the inland Bay Area and Central Coast, with patches of Major HeatRisk (corresponding to a risk for heat-related illnesses for most people without adequate cooling or hydration) for the North Bay valleys. Here are some heat safety tips:

* Stay hydrated and drink plenty of fluids.
* Wear lightweight, light-colored clothing.
* Reduce time spent outdoors or stay in the shade.
* Never leave people or pets unattended in vehicles.
* Use sunscreen if going to the coast or the pool.

LONG TERM
(Tuesday night through next Sunday)
Issued at 1256 PM PDT Mon Jun 3 2024

The heat event peaks on Wednesday with temperatures in the interior expected to remain in the mid 90s to lower 100s, with highs in the mid 60s to lower 70s expected at the coast. The Heat Advisory will extend to the South Bay and the inland Central Coast on Wednesday.
The Southern Salinas Valley is now included in the second Heat Advisory as confidence in heat impacts has grown.

Heat impacts will continue through Thursday, especially in the interior where moderate HeatRisk continues through the day, but most people should start to see a gradual cooldown as the ridge moves towards the north and east, allowing a weak trough to impact our region. A more noticeable cooldown begins on Friday, and by the upcoming weekend, high temperatures are expected to moderate to the mid 80s to lower 90s for the inland valleys and the upper 50s to mid 60s closer to the coast. CPC outlooks continue to show a lean towards temperatures above seasonal averages into the middle part of June.

AVIATION
(18Z TAFS)
Issued at 1101 AM PDT Mon Jun 3 2024

High clouds are widespread across the region this morning with MVFR/IFR CIGs around the Monterey Bay region and San Francisco Bay terminals. These conditions are expected to improve late morning/early afternoon across the Bay Area, yet may stick around for places such as KMRY. Onshore winds are forecast to increase this afternoon and continue to be breezy at times throughout the evening with gusts in the 20-25 knot range, locally stronger for KSFO. Into the evening, as high pressure sets in, and upper level winds turn to become northerly inducing directional LLWS at select terminals, expecting stratus to slowly erode as the lower levels dry out and are sapped of moisture. This should lead to widespread VFR for most terminals north of Monterey Bay. Meanwhile, KMRY and KSNS are most likely to see lowering visibilities/ceilings early Tuesday morning.

Vicinity of SFO...Currently IFR. Through late morning and early afternoon, ceilings will slowly rise to become MVFR towards noon.
Late clearing of stratus is expected in the afternoon, becoming VFR but with SCT low clouds as winds increase and gust to around 30 knots out of the west. Clouds are anticipated to continue to dissipate through the end of the TAF period leading to widespread VFR. Winds gradually diminish through late evening and into the overnight hours. Winds will begin to increase by mid-to-late Tuesday morning.

SFO Bridge Approach...Winds will be weaker over the approach.
Otherwise, similar to SFO.

Monterey Bay Terminals...LIFR conditions persist through the late morning, but CIGs are expected to lift now that the sun has risen as diurnal heating begins, eventually achieving MVFR in the late afternoon. Not expecting VFR to last long at KMRY, in fact, low confidence in clearing whatsoever. Therefore, have included a TEMPO for brief and intermittent VFR conditions in the afternoon. Winds breezy and westerly in the afternoon today should help maintain the stratus feed. IFR/LIFR ceilings and/or visibilities return in the nighttime and continue into Tuesday morning.

MARINE
(Today through Saturday)
Issued at 1101 AM PDT Mon Jun 3 2024

Moderate to fresh northwest winds persist through midweek, but increase to become strong towards Tuesday night into Wednesday with gale force gusts possible in the northern waters. Moderate wave heights will persist before rough seas build towards midweek with significant wave heights of 10-12 feet expected.
