In 2010, the hottest year on record, The Bee published a story detailing how Central Valley residents were thankfully enjoying cooler weather than the rest of the country. Central Valley farmers of heat-loving tomatoes and melons even fell behind schedule.
Bizarrely, things have flipped this year.
The National Weather Service predicts that Sacramento will heat up to a record high of 102 by 5 p.m. today - the last time it was this hot was in 1883! - and a record breaking-high of 105 tomorrow. Other places in the country are, strangely, a bit cooler than average.
Holly Osborne, a meteorologist at the Sacramento National Weather Service, said, "We don't have the El Nino cooling this year."
High pressure systems in California and low pressure systems in the eastern and mid-western parts of the country are stronger than normal, says Osborne. The abnormal systems are what have caused record-breaking May snowfalls in Iowa, Minnesota, and Wisconsin last month. Arkansas residents experienced their first May snow in history.
Brian Weare, a professor of meteorology at UC Davis, agrees that although the weather patterns have been unusual, there is no cause for alarm. "Weird things happen," Weare explains.
"It's not a hard and fast rule, but the East Coast and the West Coast tend to be opposite each other," said Weare, explaining that flip-flop between the West and East is well understood in meteorology. "A week ago, it was the opposite, we were really cool and it was really hot on the East Coast. It happens frequently. That's just the way weather works."
Central Valley residents shouldn't worry about the record-breaking heat sticking around for long. The Delta breeze - a mix of low marine clouds and strong west winds - keeps the area cool.
"Our weather would be totally different if we didn't have the Delta," said Osborne. "Up near Redding might stay in the 100s, but by Monday we'll cool down anywhere from 10-20 degrees into the 80s."
