Thursday morning's low temperature of 14 degrees clobbered the record of 18 degrees set in 1972 — and now it's time to start getting ready for snow, according to the National Weather Service.

Thursday morning's low temperature of 14 degrees clobbered the record of 18 degrees set in 1972 — and now it's time to start getting ready for snow, according to the National Weather Service.

The weather service issued a winter storm warning from 4 this morning through 4 a.m. Saturday. Two to 5 inches of snow are expected on the valley floor, and higher elevations could see a foot, with up to 8 inches expected on the Siskiyou Pass.

"Chances of snow (are) near 100 percent," said meteorologist Chuck Glaser.

After the snow falls, it'll get cold again, with a low temperature of 9 degrees forecast for Sunday in Medford.

The mercury is expected to creep back into double-digits Monday, with a low of 13 degrees predicted.

"Then it just starts warming up gradually. It'll be closer to normal by the middle of next week," Glaser said.

The 1972 record that fell Thursday was one in a series of frigid days that year.

"That was just before the real cold snap hit," said Glaser.

The days that followed in 1972, Dec. 6 to Dec. 10, saw low temperatures of 18 degrees, 1 degree, minus 6, minus 6, minus 6.

"That was a real cold one," Glaser said of the 1972 cold snap. "(Those) records are way lower than what we've got in the forecast."

Ashland and the Siskiyou Summit both reported 12-degree temperatures Thursday morning.

Crater Lake National Park also set records on Wednesday and Thursday, with minus 2 degrees and minus 1 degree, respectively, breaking records of 6 degrees and 4 degrees, according to daily weather reports from the park.
