SUBJECT: Even when we’re cold, we’re not that cold

       2002年3月1日. 云天气摘要

March in Saint Cloud was the first real winter month. 平均气温18.6 degrees at the Saint Cloud Municipal Airport was nearly 10 degrees colder than normal. This made March 2002 the 8th coldest March in the 121 years of Saint Cloud records and the coldest March since 1965. 平均最高28.0度，平均最低9度.2度 would be more typical of February 20 or 21 than of March. The high temperature on March 3 only reached 3 degrees, breaking the daily record by 7 degrees and making March 3, 2002, the 4th coldest March daily high temperature ever. There were also 6 days with a below zero low during March 2002. The normal number of below zero days in March is 3.5.

What made this March different from the earlier months? We had cold spells at the end of every month since November that persisted into the early portion of the following month. The key difference was having a snow cover and adding to it. When the early March arctic air finally receded, we got another 3.5 inches in new snow cover on the 8th and 9th. Then, when that snow finally melted, we got walloped by the March 14 storm. 这场风暴产生了10个.4英寸 at Selke Field and 15-20 inches elsewhere in central Minnesota.

The March snowfall, thanks to these storms, totaled 19.8 inches, more than 10 inches above normal. This made March 2002 the 5th snowiest March in the 102 years of Saint Cloud snowfall records. 这是自1985年以来最大雪的三月. 然而, those 4 Marches that rank ahead of March 2002 had incredible snowfalls, 到1965年3月为止, the snowiest month in Saint Cloud history with 51.7英寸. March 2002 was also the snowiest month in Saint Cloud since January 1996 (21.9英寸).

The heavy March snowfall brings the seasonal snowfall total to 48.7寸，大于5寸.在三月份比正常高出5英寸. We are now above the average cold season snowfall of 45.5英寸，尽管是温和的冬天.

While the Twin Cities didn’t make it, March 2002 was also the coldest month of this winter. It was colder than January (which had temperatures typical of March) by more than 2度. This is the first time in the 120 winters in Saint Cloud records that March has been the coldest month of the cold season. January has been the coldest month 78 times (65.0%), February was the coldest month 26 times (21.7%), and December was the coldest month 16 times (13.3%).

The melted precipitation was officially 1.51英寸. 然而, there was a problem with that total. The sleet and freezing rain during the storms of March 5-6 and March 8-9 were not included in the total melted precipitation. The SCSU accumulated precipitation during those two storms were .85 inch while the official reading recorded only .36英寸. So, perhaps half an inch of melted precipitation was lost during these storms.

然而, even when Saint Cloud records are cold this year, they are not that cold. The 6 below zero days in March brings the seasonal total to only 12 days. That is still 4 fewer days with below zero temperatures than any previous cold season. So, we have an excellent chance to break the 1997-1998 record for the fewest cold season below zero days. While March 2002 has been the coldest month of the winter, this would be only the second cold season in which our coldest temperature had an average temperature above 18 degrees. The mildest minimum reading was the winter of 1930-31 when December 1930, 那年冬天最冷的一个月, 平均气温19度.4度.

也, the coldest low temperature for this season so far has been –9 degrees, set on January 18 and tied on March 1st and 3rd. 在这个冬天之前, the mildest winter season daily low temperature was also during the winter of 1930-31 when the lowest temperature was –13, 定于11月30日和12月1日举行. So, we have never had a winter without at least one low of –10 or colder. The odds are good that we will do it this winter.

Finally, the five-month average temperature (November 1 through March 31) for this cold season is 26.1度. That is the second warmest November through March average temperature. 最温暖的? Just two years ago during the non-winter of 1999-2000 when the average temperature was 26.2度. Note also that all four of the mild winters we’ve had during the past five years are in the top 10. So, even when we are cold, we are not that cold.
