According to forecasts from the National Weather Service San Francisco (NWS SF), the San Francisco Bay Area is shaping up for a gradual warming trend in the wake of diminishing rain showers. An early morning weather synopsis highlighted isolated light showers coming to an end, with temperatures expected to rise through the week due to the influence of a strengthening ridge over the Northeastern Pacific.
The forecast for today, issued by NWS SF, also indicates a minor chance of precipitation over the eastern Santa Clara hills and the Gabilan Range into San Benito County, where some residual instability may lead to light showers during peak afternoon heating. The additional rainfall, however, is anticipated to be inconsequential for the most part, with only a few locales possibly receiving a scant amount, measured in hundredths of an inch.
Looking ahead, the long-term NWS forecast outlines an upcoming decline in the marine layer's inland reach due to high pressure over the west and a weakened onshore pressure gradient. This pattern is expected to facilitate higher daytime temperatures inland. Over the weekend, a new trough may readjust conditions, reintroducing modest onshore flow and slightly cooler temperatures.
In aviation updates for the Bay Area, MVFR (Marginal Visual Flight Rules) ceilings' erosion will lead to predominantly VFR (Visual Flight Rules) conditions by the afternoon, with winds picking up pace. The typical evening winds retreat is anticipated, alongside a marine layer resurgence causing potential IFR (Instrument Flight Rules) and MVFR conditions overnight, especially along the coast and Monterey Bay terminals.
The marine outlook is a bit less serene, with increasing winds and building seas that create precarious conditions for northern and offshore waters. Gale Warnings and Small Craft Advisories have been declared, signaling widespread gusty conditions that could persist throughout the forecast. Boaters are cautioned to stay informed and prepare for a choppy week on the water.
Concurrently, a social media post from NWS Bay Area using the KMUX Radar noted that lingering rain showers persisted earlier this morning, particularly over the Monterey Bay region. "There is around a 10-20% chance of convection this afternoon across the Gabilan Range," the post stated. As gales and showers seem to take a brief hiatus, Bay Area residents can look forward to a steady warming trend, heralding clearer skies and warmer days ahead, at least until the next system arrives.
