Boise Logs 45 Triple-Digit Days In 5 Years, More Heat Is On The Way
The National Weather Service in Boise is predicting a week of triple-digit, or near-triple-digit temperatures for the Treasure Valley.
Over the last 30 years, Boise has logged, on average, nine days of 100 degrees or warmer each year. The last two years have exceeded the average with 14 days at or above 100 in 2013, and 12 days in 2012. Data from the National Climate Data Center show Boise has had 45 days of temperatures at or above 100 degrees from 2009-2013.
Stephen Parker is a meteorologist at the National Weather Service in Boise. "We’ll get stuck in a pattern for a week or two, and those patters are hard to predict," says Parker. "After about two weeks there is no predictability in the weather."
Parker says that's when climate scientists step in, and they're modeling the future forecasts based on statistics and past patterns.
Parker says it's hard to predict just how many days at or above 100 degrees Boise will record. It's all influenced by patterns like La Nina, El Nino, and others.
In 2003, for example, Boise recorded 20 days of 100 degree weather, 15 of which were in July. That's the most days of triple-digit weather recorded since 1940. It wasn't a La Nina or El Nino year. Simply put, it was just hot.
