Yesterday's high temperature in Louisville was 30 degrees. Looking at the 10 day forecast, we're into the 40s and 50s every day, which takes us out to the second week of March, March is the month, here, when spring usually gets some traction. So: Yesterday was likely the last day of this Winter in which the high temperature failed to rise above freezing.
I may just make it through another one.
UPDATE: It is currently 33 degrees in Louisville, so my thesis holds. The next close call is Monday, March 2, when Weather.com predicts 38 degrees. If we can make it through that, WGN's first scheduled television broadcast of the Cubs is March 4.
I feel better every day.
