Freezing Rain Advisory Canceled

(3:49 a.m. Tuesday announcement)

[December 12, 2007]  The National Weather Service in Lincoln has canceled the freezing rain advisory for the counties of Mason, Logan, Cass, Menard, Scott, Morgan and Sangamon, including the cities of Havana, Lincoln, Jacksonville and Springfield. The freezing rain advisory has also been canceled for the counties of Woodford, Tazewell and McLean, including the cities of Bloomington and Normal.

Air temperatures warmed above freezing early Tuesday morning and will continue to slowly rise the rest of the day. Some light icing was possible on elevated surfaces through 6 a.m., but after that temperatures were expected to be too warm for any additional icing. Therefore, the freezing rain advisory for Tuesday was canceled.

Icing has slowed down due to warming air across central Illinois, but more icing is expected this evening as cold air returns.

West of the Illinois River, freezing rain was expected to continue Tuesday morning and redevelop in the evening. One-quarter inch or more of ice is likely from the freezing rain there, mainly on elevated surfaces. Warmer air from the south has shut down the freezing rain in the advisory areas.

An ice storm warning remains in effect until midnight Tuesday for the counties of Knox, Stark, Peoria, Marshall, Fulton and Schuyler, including the cities of Galesburg and Peoria.

Some freezing rain was expected to continue there Tuesday morning and again in the evening. Temperatures will warm slightly above freezing by afternoon, but icing was expected to continue on elevated surfaces Tuesday morning, especially on trees and power lines. Colder air will move back south Tuesday evening, and additional icing is expected then. This extended period of freezing rain will likely deposit over one-quarter inch of ice west of the Illinois River.

Power outages will be possible as ice-coated tree branches possibly fall into power lines. Winds have remained light so far, which has helped keep power outages minimized. However, during the day a few wind gusts over 10 mph may be enough to break the heavily weighted icy branches.

An ice storm warning means severe winter weather conditions are expected or occurring. Significant amounts of ice accumulations will make travel hazardous. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency. Ice accumulations and winds may lead to snapped power lines and falling tree branches that add to the danger.
