This year’s growing season lasted 201 days, making it the second longest stretch in Idaho’s year of going without freezing temperatures, according to the National Weather Service.
A growing season is measured from the last freeze date of spring to the first freeze date in the fall, said Dave Groenert, meteorologist for the National Weather Service.
Wednesday night marked the first freeze of the season with a low of 29 degrees, he said.
The longest Treasure Valley growing season on record lasted 207 days in 2005, Groenert said.
The Boise area will have cold temperatures ahead in the week. The high Thursday is expected to be 45 degrees with a low predicted to be 32 degrees. The high Friday is predicted to be 49 degrees with a low of 32 degrees. The most likely chance for precipitation will be Sunday when there will be a 40 percent chance of rain, he said.
The temperatures are recorded at the Boise airport, which runs warmer than the rest of the Treasure Valley, so other spots may have already been hit with a freeze, Groenert said.
