In looking at statistics for Sunday (March 19), I noticed three unusual occurrences: The high for the day was at 9:54 a.m.; the temperature range for the day was only 12 degrees; the high and the low occurred only one hour and 22 minutes apart. The latter statistic seems particularly unusual. Can you recall a day's high and low ever being closer together?

T his is going to happen only on a humid, usually rainy, winter day. I had to go back only to Feb. 11, 2005, to find a day when the temperature range was only 5 degrees (60 and 55). There were three days last February when the range was less than 10 degrees. I have seen instances in the Midwest where the high and low were the same temperature — it was the same temperature all day.
