Tim's Weather World: Big Snow But No "Snowmageddon"

Forecasters out east have coined the phrases “Snowmageddon” and “Snowpocalypse” to describe the nasty series of storms they have experienced this winter.  New York City has a blizzard warning in effect today.  Washington DC has seen 48.8″ of snow so far this season (not including today’s storm).  That is almost five times more than they see in an average winter to date.  Ironically, a senate hearing on global warming was postponed in DC because the snow.

Our snowfall for the season is getting impressive also.  The 12.6″ of snowfall at O’Hare yesterday ranks as the 7th biggest single calendar snowfall on record.  It was also a record snowfall for the date and the most snowfall for a single day in February.  It brings our seasonal total up to just under 45″, nearly twice the average to date.  Tuesday’s storm hit northern Lake County the hardest with 14″ in Antioch.



SnowPhoto.jpgAs if the snowstorm itself wasn’t enough to talk about today, we experienced a 4.3 magnitude earthquake centered near DeKalb this morning.  Before you push the doomsday clock forward though, keep in mind that earthquake’s aren’t that unusual for IllinoisClick here for a look at the history of Illinois earthquakes.  I experienced my first earthquake early on the morning of April 18, 2008 when a 5.4 earthquake hit downstate Illinois.

Snow to continue overnight but gradually shift east into Indiana

The snowstorm is winding down after dropping more than a foot of snow in many areas from the city north and near the lake to 5-10 inches in southern sections.

At 1 am radar still showed a strong band of lake-effect snow still affecting areas near the lake in Illinois and northwest Indiana. This band will continue overnight and gradually shift east  moving totally into northwest Indiana by morning  as the steering winds slowly back from north to northwest.
