Is Chicago's 2009-10 snow season finished?

Dear Tom,
As you have mentioned, Chicago’s snow total this season is near 55 inches, and the north suburbs have had even more. But with April only a few days away, can I assume that’s it?

–William Morrison, Waukegan

Dear William,
Chicago’s snow season is winding down, but it’s premature to dismiss the possibility of additional snow at the end of March. On average, the city’s full snow season delivers 36.8 inches with 97 percent of it coming down by April 1. That means 3 percent, or 1.2 inches, is yet to occur.
The weather isn’t bound by those climatological averages, of course, and only 66 Aprils out of 125, or 53 percent, have produced measurable snow (at least 0.1 inch). Significant snows, arbitrarily defined as 3.0 inches or more, occur in 1 out of 4 Aprils, and 1 out of 20 Aprils have a storm of at least 6.0 inches.

Winds top 40mph on March 25th

 A wicked northeast wind off of Lake Michigan brought Spring to an abrupt halt on Thursday.  Winds topping 40mph coupled with temps in the 30s resulted in a wind chill index that fell into the teens at times.

Winds overnight will slowly diminish and the outlook for Friday is for a much calmer day.

Here are a few of the stronger wind gusts from across the Chicago area

52mph   Chicago- Harrison Crib

47mph   Gary, IN

43mph   Chicago- O’Hare

43mph   Chicago- Midway

40mph   Wheeling

40mph   Waukegan

47-degree swing heading Chicago's way

Talk about a temperature roller coaster; that’s the head-spinning ups and downs in readings in store for Chicago area residents in upcoming days. From Friday’s forecast minimum of 23 degrees to Wednesday’s projected high of 70, the area could experience a temperature surge of 47 degrees, but it won’t be a steady ride — there will be ups and downs along the way.

Florida’s cold winter

With the official arrival of spring this past weekend, a record cold winter at Key West (the southernmost city in the continental United States) came to a close. The winter (astronomical winter, Dec. 22 to March 20) there had an average temperature of 65.3 degrees, tying the winter of 1977-78 as that city’s coldest. Chicago’s winter temperature average was 28.6 degrees, nearly 37 degrees colder

Do weekends in Chicago have lousier weather?

Dear Tom,
It seems that the weather on the weekends is inclement more often than during the week, but this defies logic. Can you shed some light on this issue?

Tim Mallis
Dear Tim,
There’s a name for a sunny day that follows two cloudy, rainy days: It’s called Monday. That joke has been floating through the meteorological community, and elsewhere, for as long as we can remember, and it certainly seems to have validity. We all have memories of weekend plans disrupted by the weather or outdoor weekend events that were washed out — and that’s the key to the source of the “rainy weekend” syndrome. We remember the disruptions and washouts. However, a computer scan of Chicago’s precipitation records reveals that precipitation does not have “favorite days.” Averaged through the years, precipitation falls on one day out of three, regardless of the day of the week.
