SYNOPSIS
Issued at 230 AM PDT Tue Jun 4 2024

Warm to hot inland, coolest at the immediate coast today. A Heat Advisory is in effect for inland areas today through Thursday.
Temperatures will moderate towards the latter part of the week.

SHORT TERM
(Today and tonight)
Issued at 247 AM PDT Tue Jun 4 2024

Sky condition is clear (allowing improved radiative cooling vs cloud cover 24 hours ago) except for few-scattered thin high clouds and patchy morning mist or fog along the immediate coastline within a marine layer varying from a few to several hundred feet deep North Bay to 1600 feet deep over the north Central Coast.

The advertised Heat Advisory goes into effect today for the North Bay and the East Bay (the advisory expanding to include areas of the South Bay, interior Monterey county including the southern Salinas Valley and San Benito county Wednesday-Thursday).

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.

Highs today will be mainly above to well above early June normal high temperatures. Highs will be coolest along the immediate coastline/beaches with 70s to a few warmer spots not far from the beaches in the lower 80s, bayside highs will be 80 to 90 with lower 90s just away from the SF Bay. Farthest inland highs today in the 90s to near 100 degrees far northern Napa county, easternmost Contra Costa county and far southern Monterey county.
The Santa Rosa coop station may near the June 4th record high 98F in 1949.

LONG TERM
(Wednesday through Monday)
Issued at 247 AM PDT Tue Jun 4 2024

As mentioned, the heat advisory continues inland areas Wednesday and Thursday. Warm to hot daytime highs, above to well above June normal highs - hottest inland with 90s to lower 100s, nearer the coast 80s and 90s, and 70s/80 at the beaches. Hot weather will result in elevated fire weather conditions at least through Thursday. Improving chances of patchy night and morning coastal stratus and fog redeveloping later in the week. The NAM forecasts the SFO-SAC pressure gradient (westerly winds) prevailing Thursday afternoon and evening, however it still make take an extra day or two for the afternoon sea breeze to bring some relief farther inland.

A high pressure system is forecast to remain nearly stationary over the west late this week into next week, surrounded by low pressure systems of various strength. Weak upper level troughing may reach California over the weekend, the daily sea breeze likely during then bringing relief at least partially inland each afternoon and evening.

AVIATION
(12Z TAFS)
Issued at 431 AM PDT Tue Jun 4 2024

VFR except for a patch or two of stratus and fog /LIFR-IFR/ along the immediate coastline this morning. The NAM forecasts the ACV-SFO pressure gradient to strengthen to nearly 9 mb by later today, the UKI-STS pressure gradient strong at 2 mb to 3 mb. Local influxes of cooler marine air will continue nearest the immediate coastline, for example statistical guidance is forecasting a gusty west wind to around 30 knots at KSFO this afternoon and evening. Additionally, the leading edge of stratus and fog approx 300 miles northwest of the Bay Area where surface dewpoint temps are higher is forecast to reach our coastline late tonight and Wednesday morning per recent HRRR output; coastal waters sea surface temperatures remain chilly which favors coastal stratus and fog.

Vicinity of SFO...VFR. Light west wind this morning, increasing to 22 to 32 knots beginning 21z and continuing to mid-late evening.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR. Light and variable winds this morning, becoming west to northwest winds 5 to 12 knots during the day.
Patchy stratus and/or fog /LIFR-IFR/ early Wednesday morning.

MARINE
(Today through Sunday)
Issued at 252 AM PDT Tue Jun 4 2024

Breezy to gusty north and northwest winds affect all of the waters through the mid week. Meanwhile, large NW swell will arrive in the coastal waters of Northern and Central California. These rough seas will last through Thursday. Conditions will then gradually improve going into the weekend.

BEACHES
Issued at 859 PM PDT Mon Jun 3 2024

A Beach Hazards Statement is in effect from Wednesday morning through Thursday evening.

A moderate-rough NW swell will arrive Wednesday and create large breaking waves and an increased risk for sneaker waves. Breaking waves will reach as high as 15-20 ft, especially along steep beaches. Sneaker waves can run over 100 ft up a dry beach, pulling people in the water from rocks, jetties, and beaches. Inexperienced swimmers should stay out of the water. Observe the ocean for 20 minutes before relaxing on the beach. The hot weather inland will lead to more people visiting the beach this week. Know where lifeguards are, obey their instructions, and never turn your back on the ocean!
