Was March colder than normal?

Nearly everyone is happy to see March 2013 end, as it was an unusually persistent cold month. In fact, Madison ended up 7.4 degrees below normal for March 2013 making it the 18th coldest March in the city’s history.

How cold has this winter been, historically?

Wednesday is the 62nd anniversary of the coldest day ever in Madison — Jan. 30, 1951 — when the temperature dropped to minus 37 F.

As we described in a column a couple of years ago, to get the air that desperately cold in Madison a healthy snow cover is necessary. This January, we had a warm spell near mid-month that effectively melted most of the snow remaining from our December snowstorm. Thus, even though last week’s cold was the worst of the season thus far, it was a lot less cold than it might have been had it occurred while we had a deep, fresh snow cover. Continue reading
