The Bay Area is gearing up for a mix of weather patterns this week. While Monday kicks off with minimal cloud cover and a warming trend, temperatures are set to climb, reaching into the mid-80s to 90s for inland areas and the more temperate mid-60s to 70s closer to the coast. Evening temps won't give much respite, staying snug in the upper 50s to mid-60s in most places, as per the latest National Weather Service San Francisco forecast.
Heads up for Tuesday, as it's expected to be the toastiest day of the week. With moderate to major HeatRisk conditions forecasted, those in the East Bay and portions of Santa Clara County should be especially vigilant. In a curious turn of nature's whims, Tuesday is also slated to mark the return of rain showers and thunderstorm chances that could persist through midweek, with storms anticipated to be significant enough to reduce the risk of dry lightning, courtesy of the high atmospheric water content, referred to as PWATs in meteorologist lingo, ranging from 1.0 to 1.4 inches.
Looking further, a cutoff low-pressure system, currently off Baja California, is poised to mosey northward, potentially sling moisture across the region. As this slow-moving guest makes its way east by Thursday, residents can expect a gradual return to typical September weather patterns for Northern California.
On the aviation front, pilots and passengers should encounter mostly clear skies, as "LIFR CIGs and pockets of fog" only affect coastal spots like the Monterey Bay early in the day. According to the National Weather Service, these conditions should lift by late morning, paving the way for "widespread VFR" visibility and moderate afternoon winds. Nightfall, however, will see the return of clouds hugging the coastline, setting the stage for potential navigational adjustments at regional airfields.
Marine enthusiasts take notice: the northern waters are maintaining their breezy disposition, conjuring up some particularly choppy seas, especially near and north of Point Reyes. Meanwhile, a northwesterly swell is expected to dominate the salty stage throughout the week, with conditions mellowing south of Point Pinos. There, seafarers will encounter a more laid-back southerly swell, averaging a mere 2 to 3 feet.
