It may be getting colder outside, but Medford's resolve in not dipping down to the freezing mark is one for the history books.
National Weather Service meteorologists said the city has not hit 32 degrees or lower since March 23, or 230 days as of Thursday.
"That is the longest stretch without it hitting 32 in our entire climate record, which goes back to 1911," said NWS meteorologist Brett Lutz.
The second longest stretch stretches to 1937, which ended its 219-day run on Nov. 28.
Not to say it hasn't been close. Temperatures dipped down to 34 a couple of times, once in April and once in October. And the streak may be nearing the end of its run, perhaps as early as tonight.
Forecasters say the thermometer should drop to 32 degrees. Saturday night looks to be even more likely, with predicted low temperatures of 28.
The surrounding mountains are also due for their share of winter. The Southern and South Central Oregon Cascades ranges could see up to 4 inches of snow by this morning, according to an NWS statement released Thursday.
"We should see snow on the hills," said NWS meteorologist Connie Clarstrom.
NWS officials issued a winter weather advisory Thursday, saying it would be in effect until 4 a.m. today. A winter weather advisory means periods of snow that could cause potential travel difficulties for motorists. Locations affected by the snowfall will include Interstate 5 at the Siskiyou Summit, Crater Lake, Crescent Lake, Diamond Lake and Howard Prairie. Mt. Ashland could also see up to 4 inches of snow.
In addition to Interstate 5, motorists should be prepared for hazardous driving conditions on Highway 140 near Lake of the Woods, Highway 66, Highway 62 near Union Creek and Crater Lake, Highway 230, Highway 58 at the Willamette Pass and Highway 138 at the Diamond Lake summit.
Winds are also expected to reach up to 15 mph. A chance for additional rain and snow will extend into tonight.
"We're not expecting it to accumulate," Clarstrom said.
