New UPDATE, MARINE

SYNOPSIS
Issued at 1231 AM PDT Fri Jun 21 2024

Warm temperatures across the region today and Saturday. A Heat Advisory comes into effect on Saturday for the interior regions with a moderate risk of heat-related illnesses. Temperatures moderate through the early part of next week.

UPDATE
Issued at 845 AM PDT Fri Jun 21 2024

Low clouds across the interior are already dissipating with the trend expected to continue. Near the coast, stratus is likely to persist through much of the day with only brief breaks in the cloud cover as a moderate marine layer remains in place (around 1,800 feet at Fort Ord). With that said, the on going forecast remains on track with no updates anticipated this morning.

SHORT TERM
(Today and tonight)
Issued at 1231 AM PDT Fri Jun 21 2024

Marine layer stratus is developing again tonight with the Fort Ord profiler showing a marine layer depth of 1500 feet and a robust onshore pressure gradient, with SFO-SAC showing a +3.9 mb gradient as of the last update. Expect the stratus to continue expanding across the inland valleys through the night before the morning sees the stratus pared back to the immediate coastal regions. Tonight's lows remain in the upper 40s to mid 50s across the lower elevations, and into the upper 50s to lower 60s in the higher elevations.

Today sees the first day of a significant warmup in temperatures as an upper level trough fades into a ridge moving into the western United States. High temperatures today will range from the mid 80s to the mid 90s in the inland valleys, perhaps close to or at 100 in the warmest spots of the northern North Bay, eastern East bay, and southern Central Coast. Elsewhere, expect highs near the low to mid 60s along the coast and in the 70s for the Bayshore.

We begin to see Moderate HeatRisk in some of the interior regions today, most notably the interior East Bay, South Bay, and southern Salinas Valley. This means that there is a risk of heat-related illnesses for most people sensitive to heat, including children, the elderly, pregnant women, those working or living outside, and those with certain medical conditions. Here are 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
(Saturday through Thursday)
Issued at 1231 AM PDT Fri Jun 21 2024

Temperatures peak on Saturday, with highs ranging from the mid 90s to the mid 100s in the inland valleys, the mid 70s to mid 80s for the Bayshore, and the 60s and low 70s along the Pacific coast. A Heat Advisory will be in effect on Saturday for the interior North Bay mountains, East Bay, South Bay, and Central Coast, where Moderate HeatRisk continues through the day.

Sunday should be noticeably cooler with an upper level trough to our west beginning to promote stronger onshore flow. High temperatures will drop into the mid 80s to the low 90s in the interior valleys (perhaps close to 100 in the warmest spots), the 70s into the lower 80s along the Bayshore, and the upper 50s to the 60s along the coast. Expect these temperatures to continue into the next work week. Beyond that, CPC outlooks continue to suggest chances for temperatures above seasonal averages (around 33-50% probability) and precipitation near or below seasonal averages into the first few days of July.

AVIATION
(12Z TAFS)
Issued at 410 AM PDT Fri Jun 21 2024

Stratus remains socked in over all terminals along the coast creating a mix of MVFR/IFR/LIFR conditions. High confidence that stratus will lift and erode back to the coast, allowing for VFR to prevail through the remainder of the TAF period, except KMRY where stratus is expected to return Friday evening. Models do hint at MVFR/IFR conditions returning for some terminals, but with the warmer temperatures, and drier conditions, confidence were low to include lower CIGs at this moment. Onshore winds will remain light to moderate before rebuilding Friday afternoon with possible gusty winds through coastal gaps and passes.

Vicinity of SFO...IFR will continue until the early morning where VFR will return. Models hint at MVFR ceilings returning Friday night, but with the ridging pattern, there is a higher chance for VFR will prevail for the remainder of the TAF period. Winds will become breezy and gusty up to 23-25 knots Friday afternoon, before returning to light Friday night.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR conditions, but there are chances for temporary LIFR ceilings for the next few hours. VFR conditions are expected near 17-18Z. KMRY IFR/MVFR conditions may linger a bit longer into Friday morning, but higher confidence between 18-19Z.
Models show good agreement of possible IFR/LIFR conditions for KMRY Friday night, but still some uncertainty on timing and ceiling height.

MARINE
(Today through Wednesday)
Issued at 845 AM PDT Fri Jun 21 2024

Moderate to fresh northwesterly winds prevail into the weekend with strong near gale forced winds over the northern outer waters.
These stronger gusts may pose hazardous for small craft.
Significant wave heights of 6-8 feet will persist until the end of the week, then build back up to 10-12 feet over the outer waters for the weekend, when northwest winds increase once again over much of the waters. Light southerly swell continues to move through the waters today, accompanied by moderate NW swell.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Heat Advisory from 11 AM to 10 PM PDT Saturday for CAZ504-510- 513>518.

PZ...Small Craft Advisory until 9 PM PDT Saturday for Pigeon Pt to Pt Pinos 10-60 NM-Pt Arena to Pt Reyes 10-60 NM.
