Hints our month long mild spell may yield to chilly air as February nears
Published January 17, 2006
The extreme level of warmth which has dominated the nation's heartland since January's open isn't any more sustainable than the abnormal chill with which Winter, 2005-06 opened in December. Double digit, multi-week surpluses are by nature on thin ice and this one is no exception. When it breaks, it may do so with a meteorological bang. Warmth has limited ice accumulations to shoreline areas or the bays of the northern Great Lakes. Lake Michigan's 41.5(degrees) temperature is 3.5(degrees) above the 10-year average and the warmest single lake surface temperature since at least 1995. When arctic air next makes contact with the mild, ice-free Great Lakes, snow development is likely to be explosive. A series of 16-day computer forecasts suggest a dome of mild air may rebuild late this month over the North Atlantic. That's similar to December's pattern and suggests arctic air may again be forced south into eastern North America in time for February's arrival.
Translation: Cold air and lake-effect snow are on the way. Let's hope the winds are from the west; as soon as they go north or east, Evanston and the North Shore will get hammered. Should be fun!!
