– Denver is set to see a bigger temperature change in the space of a day than some places experience over a year, forecasters say. "The forecast has a bit of Yin & Yang in it over the next two days," the National Weather Service tweeted Tuesday. "Near record heat tomorrow, light snow arrives Thursday." The Wednesday temperature ended up being a record 84 degrees, 4 degrees higher than the previous record for Oct. 25, which was set in 2007, CBS reports. But the winter coats will be coming out Thursday: The Denver Post reports that after a wind change, the temperature is expected to drop to the mid-30s by afternoon, followed by an overnight low of around 20. Around half an inch of snow could accumulate after lunchtime Thursday, rising to up to 5 inches at higher elevations.
