Temperatures in Boise climbed to 65 degrees Friday afternoon, just 1 degree lower than the record, which was set in 1950, the National Weather Service reports.
And it was even warmer — 67 — in Caldwell, but the weather service doesn't keep records for high temperatures in that city, meteorologist Stephen Parker said.
Throughout the Treasure Valley, it was the warmest day so far this year, he said, but highs will slip back into the 50s starting Saturday. Still, he said, it will be warmer than usual for this time of year.
"We're going to be above average, it looks like, for the next 10 days or so," Parker said.

Saturday's forecast high of 56 degrees is seven degrees above the average for that date, and Sunday will be the warmest day next week, with an expected high of 59 degrees, he said. The forecast high drops to 52 degrees for Monday.
Weather systems moving into the area will likely bring light rain to the Treasure Valley Saturday morning and Sunday evening, he said.
