Californians can expect hotter-than-average temperatures this summer.

The National Oceanic and Atmospheric Administration (NOAA) predicts that the weather for June, July and August will be warmer than normal.

The temperature map shows that in California, especially in northern parts of the state, there will be a 33% to 50% probability that temperatures will be above average.

The week is starting off chilly in the Bay Area. Here’s when it will finally warm up

in Weather

The Bay Area is creeping toward a warm-up this week, but will have to endure more unseasonably cool weather before getting there. Parts of the region have seen their coldest beginning to May this century, and the week starts off with high temperatures expected at 5 to 10 degrees below normal.

Light rain showers and morning fog also will be around before a warm-up arrives with the weekend.

The average high temperature in San Francisco for the first six days of May was 60.2 degrees, the coldest beginning to the month since 1975’s average of 58.5 in the same time frame. It won’t get much warmer until Thursday and Friday, the forecast shows, with highs barely surpassing 60 in the city.

California heat wave: This Bay Area city has the highest chance of breaking record high

in Weather

The first heat wave of the year is expected to peak in the Bay Area on Thursday. Rounds of hot and dry air from a powerful high-pressure system are flowing into the region, clearing out the spring’s marine layer. This will especially be the case in the region’s inland valleys, where temperatures are expected to soar to the upper 80s and lower 90s.

These are unusually warm temperatures for April, even for inland cities like Napa, Livermore and Santa Rosa. And depending on the timing of some of the hot air, a few spots will be just shy of temperature records for the day — one city might even surpass its record.

Here’s how much rain and snow is heading to Northern California this weekend

in Weather

The calendar may have turned a page, but the rain-making systems that impacted California throughout February will stay strong through the first weekend of March, bringing more rain to the Bay Area and heavy snow to the Sierra Nevada.

After the past few days served as a brief respite from a parade of storms, colder temperatures and a chance of precipitation will return by daybreak Saturday and persist through the weekend.

Bay Area gets a short break from winter storm. Here’s when the rain and snow will return

in Weather

But the intense onslaught of winter weather will come to a pause today. A high-pressure system off the coast of California will spread into the Bay Area and Sierra Nevada this morning. Look for mostly sunny skies and a steady stream of warm daytime temperatures this afternoon and over the next few days as its warm, dry air reaches all corners of the state, stomping out any lingering rain and snow showers. But the high-pressure system’s brief pause in wintry weather will last only through Friday afternoon.

Stormy weather to start the week: Here’s the timeline for Bay Area rain, snow and wind

in Weather

The Bay Area is waking up Monday to another round of soggy weather that’s expected to last until midweek.

A low-pressure system churning off the Oregon coast is funneling moisture from the ocean, bringing periods of moderate rainfall and a chance of thunderstorms to the Bay Area, with snow around 2,500 feet for the region’s mountains. In the Sierra Nevada, blizzard conditions.

The offshore weather system is part of a trough pattern, a large area of low pressure. As the trough dips down and moves closer to Northern California, winds will be gusty, and temperatures will be running colder than normal.

California is bracing for back-to-back winter storms. These are the biggest impacts

in Weather

A series of winter storms will work together to usher in some of the coldest and windiest conditions of the season across California. These winds will be accompanied by waves of atmospheric moisture that will crash into Northern California from Wednesday to Friday morning.

Widespread rain showers will impact most of the Bay Area on Wednesday through Friday, while periods of snow showers will be possible farther inland — including the Sierra Nevada and some foothills near the coast. These winter storms will also hoist thunderstorms onto the coastline, raising the chances for small hail and ice pellets in areas along Highways 101 and 1.

By Friday afternoon, the bulk of this winter weather will spread south of San Luis Obispo and into the L.A. Basin, causing dangerous driving conditions along the Grapevine and Cajon passes while also raising chances for snow as far south as San Diego County. The stage is set for a week of active weather all across the Golden State.

Freeze warning issued for Sonoma County, low of 29 degrees expected in Santa Rosa

in Weather

A freeze warning for Sonoma County has been issued by the National Weather Service, with temperatures early Wednesday morning expected to dip into the upper-20s in the valleys, weather officials said Tuesday.

The county’s mountain areas should be slightly less cold, with temperatures between the mid-30s to around freezing, said Rick Canepa, a weather service meteorologist.

The freezing temperatures are caused by another cold front coming from Siberia, he said. The freeze warning has been issued for between 2 a.m. to 9 a.m. Wednesday.

Coldest air of the winter to hit the Bay Area today. Here’s why

in Weather

Freezing, northwest winds will quickly sweep across the Bay Area today, dropping daytime highs by 7 to 10 degrees in parts of the region. This rush of bitter, cold air will be enhanced by today’s passage of a cold front, which will leave a trail of frost in its wake. Today’s cold snap will introduce some of the coldest air of the winter season, with temperatures in inland cities like Walnut Creek and Santa Rosa falling to the lower 30s by tonight.

The coldest day (and night) of the season

Residents on the coast will be waking up to temperatures in the lower 40s for the first time in weeks, with a few patches of the shoreline potentially falling to the upper 30s before sunrise. This unusual weather setup on the coast will be driven by an amped up cold front.

Oftentimes, these fronts struggle to drop temperatures in the coast and bays of the region thanks to the influence from warmer sea-surface temperatures. But this week’s setup will be different, and that’s because of just how strong this upcoming cold front is shaping up to be.

After brief Bay Area warm-up, wind and cold air will surge back in this week. Here’s the outlook

in Weather

The Bay Area can expect another roller-coaster ride when it comes to temperatures this week.

After a cloudy and cool Saturday, skies were sunny and temperatures warmed up to near average for Super Bowl Sunday. The sunshine and warmth will hang on for Monday, as the ridge of high pressure weakens and slowly heads south.

But then a trough, or an area of low-pressure, will usher in colder air, sending temperatures back down.
