Christmas Eve Climatology

It’s the most wonderful time of the year…..for many! The holiday season is in full swing and Christmas Eve 2012 is shaping to up be an average weather day in northern Illinois and southern Wisconsin.  The average high in Rockford for December 24 is 31 degrees, the forecast high for this year.  The average low for the date is 15 degrees, a handful of degrees colder than the forecast low.  There’s even the chance for a few snow flurries and patchy light freezing drizzle.  On average, a few tenths of an inch of snow can fall on Christmas Eve.  Very minor to no snow accumulation is in this year’s forecast.

Christmas Eve can have extreme weather, too.  It’s been as warm as 55 degrees in 1982.  The very next year, 1983, temperatures plummeted to the record low of -11 degrees.  In 1965, the rainiest Christmas Eve occurred with 1.77 inches of rain.  The most snow ever recorded was nearly a century ago, with 8 inches in 1918.

The last time it snowed on Christmas Eve in Rockford was in 2010, when 3.9 inches of snow was recorded at the airport.  Major snowfall does not normally occur on December 24th, however.  Since records began in 1906, there have only been 10 times where 1 inch of snow or more was observed in Rockford on Christmas Eve.
