Downtown Davenport’s new outdoor winter event Icestravaganza had to be postponed Sunday because of ice, of all things.

A winter storm is expected to hit the Quad-City region Sundaymorning, bringing freezing rain, sleet and some snow, according to the National Weather Service, Davenport.

About 0.1 to 0.25 inches of ice is expected, which could cause power outages as the ice forms on power lines, meteorologist Tim Gross said.

“We’ll start out the morning at about 24 degrees,” Gross said. “By about 10 a.m. the temperature should be about 27 degrees.

“We’re expecting that freezing rain between about 10 a.m. to noon,” he said.

“We’ll have about an hour to a two-hour window of freezing rain,” Gross said. “We’re expecting the temperature to climb above freezing by about 1 or 2 p.m. and then the precipitation will turn to all rain. So the ice won’t be around long.”

However, the ground temperature will still be colder than the air temperature, so the ice on the ground will take a bit of time melting, he added.

The rain will begin tapering off about 6 p.m., Gross said.

The high temperature Sunday is expected to reach 35 degrees. A southerly breeze will continue pumping warm air into the region throughout the night so that the mercury should reach 40 degrees by about 4 a.m. Monday.

Icestravaganza organizers hope to reschedule the event in February. It was to run from noon to 6 p.m., with ice carving demonstrations, ice skating in a temporary rink in the courtyard by the sky bridge entrance on 2nd Street, live music, a Diamond in the Ice contest, horse-drawn carriage rides and shopping in the sky bridge with local vendors.
