Here’s the Thanksgiving holiday weather forecast — and what it means for your travels

in Weather

The atmospheric kitchen is cooking up everything from fire weather to rain and snow for California’s holiday weekend. Each part of the state will get a chance to taste one or more of these weather dishes as they build up on the platter over the next few days.

This hodgepodge of weather is being stuffed into the state by two competing weather systems. The first will be a dry, high-pressure system that will raise temperatures, winds and fire concerns for parts of California on Thanksgiving Day. The second will be a low-pressure system that will dip into Northern California on Saturday night and into Sunday, potentially creating a slick, rainy situation for travelers trying to get back home. Some holiday travelers may even wind up dealing with snow before all is said and done.

Both systems will roll into California at the start and end of the holiday weekend, and each one will bring its own unique spin for travelers to navigate.

Mild weather continues, then a sunny Thanksgiving is on tap for the Bay Area

in Weather

The frigid mornings recently have become part of the routine, during a cold snap that’s affected the Bay Area this month. The coldest lows are in the North Bay valleys, with spots that can get to the mid-30s. Another chilly location is the interior East Bay, where lows could be in the upper 30s. Even though the mornings have been pretty cold, the weekend was overall mild, due to a ridge pattern, an area of high pressure that promotes clear skies and dry conditions. We can expect more of the same temperatures for Monday, as a ridge slowly moves east.

Offshore winds rolling into California today. Here’s how they’ll impact the Bay Area

in Weather

It’s a cold morning across the Bay Area but temperatures are about to take a bit of turn today. Warm, dry air is filtering into the Napa Mountains and Diablo Range. This air will accelerate as it pools into San Francisco Bay, clearing out any lingering clouds and fog in its tracks.

It was only a matter of time before these dry, offshore and northeast winds – aka the Diablo winds — made their appearance. Southern California is also set to see the return of its Santa Ana winds while the Santa Barbara coast can expect Sundowners all along the Pacific Coast Highway.

Given all the rain and snow we’ve seen over the past few weeks, how concerned should Californians be about new wildfires during this week’s wind event? Depending on which part of the state you live in, the answer will vary quite a bit.

Where will the next big Bay Area earthquake shake?

in News

Predicting where and when the next “big one” will strike the San Francisco Bay Area is a tough task for seismologist. Five major fault lines cross the Bay Area: San Andreas, Calaveras, San Gregorio, Hayward and Rodgers Creek.

A fault is defined by the U.S. Geological Survey as “a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake – or may occur slowly, in the form of creep.”

Without enough creeping, pressure will build up until an earthquake results.

Tuesday’s 5.1 magnitude earthquake originated from the Calaveras Fault and its epicenter was just east of San Jose. Fortunately, San Jose emerged without significant damages nor injuries. Still, the USGS cautions, “we live in earthquake country and we should all be prepared for the next big quake.”
