Colorado is in for an abrupt start of summer this weekend after a wet and chilly spring. Temperatures are expected to rise into the 90s around the Denver area, and above 100 in Grand Junction.
That’s not unusual, but it could feel like a big change, says meteorologist Nezette Rydell with the National Weather Service in Boulder.
"We generally do warm up pretty rapidly. It seems a little more exaggerated this year because of the prolonged rain period which kept us cooler than we might have otherwise been," she says.
Mountain streams will stay high as warmer temperatures melt off more snow, but Rydell says forecasters aren’t concerned about serious flooding.
