New AVIATION, MARINE

SYNOPSIS
Issued at 1251 AM PDT Thu Jun 20 2024

An eroding upper level trough is promoting a warming trend through the weekend, with above average temperatures Friday and into the weekend.

SHORT TERM
(Today and tonight)
Issued at 1251 AM PDT Thu Jun 20 2024

Marine layer stratus is developing inland and is expected to expand throughout the valleys as the nighttime progresses, aided by an expanded marine layer of 1500-2000 feet and robust onshore pressure gradients. This morning's lows hover in the upper 40s to lower 50s in the lower elevations, up to the upper 50s to near 60 in the higher elevations.

The upper level trough that settled in and cooled us off yesterday is beginning to erode, with a slight warmup expected today as high temperatures rise into the upper 50s to lower 60s along the coast, the upper 60s to mid 70s in the Bayshore, and the 80s into the lower 90s in the interior valleys. Stratus clouds will retreat to the immediate coastal regions as breezy onshore winds set up in the afternoon, with gusts up to 20 to 25 miles per hour through the gaps and passes.

LONG TERM
(Friday through Wednesday)
Issued at 1251 AM PDT Thu Jun 20 2024

The upper level trough continues to erode throughout the rest of the week, with a weak but noticeable ridge coming by the weekend. By Saturday, we should see high temperatures in the low 100s for the favored warm spots, such as the northern reaches of Napa and Sonoma Counties, eastern Alameda and Contra Costa Counties, and southern Monterey and San Benito Counties. A Heat Advisory will be in effect on saturday for the interior North Bay mountains, East Bay, South Bay, and Central Coast. Moderate HeatRisk is in effect for these areas, meaning 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.

The heat will begin to abate during the early part of next week, although temperatures remain warm with highs around or a few degrees above seasonal averages. Model ensemble clusters are hinting at a trough coming through the western US towards the end of next week, although details remain murky.

AVIATION
(12Z TAFS)
Issued at 402 AM PDT Thu Jun 20 2024

CIGs have filled across the region. Pockets of fog look to form into the early morning in the North Bay and along the coast. Winds will be light to moderate through the late morning before breezy winds arrive into the afternoon. CIGs dissipate for all but the Monterey Bay terminals in the mid to late morning, with those terminals seeing some brief clearing into the afternoon. Winds reduce into Thursday evening as MVFR and IFR CIGs begin to affect the Monterey Bay and SF Bay terminals. Expect widespread CIGs again late Thursday night as stratus pushes well inland.

Vicinity of SFO...IFR lasts through the late morning with moderate westerly winds. Expect CIGs to clear as a round of breezy winds start build with peak gusts around 26 kts. IFR CIGs arrive in the evening, with winds reducing into the night.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR lasts through the night and into Thursday afternoon light to moderate winds. CIGS erode into late morning and early afternoon as moderate to breezy winds arrive.
Winds at the terminals reduce into the early evening as IFR CIGs move inland.

MARINE
(Today through Tuesday)
Issued at 402 AM PDT Thu Jun 20 2024
