September 2001 Saint Cloud Weather Summary

This Month's Daily Statistics

SUBJECT: How Dry We Are…Again
         Saint Cloud September 2001 weather summary


     For the fourth consecutive month, rainfall was well below normal in Saint Cloud. According to the September 2001 statistics at the Saint Cloud Municipal Airport, only 1.77 inches of rain fell during the past month, more than an inch below normal. More than half of that rain fell on September 7th when St. Cloud was hit by two waves of thunderstorms.

     The low rainfall continued the trend of the dry summer. The four-month rainfall total of June through September amounts to just over eight and a half inches, which is the 10th lowest rainfall total for the four-month period and is more than six inches below normal. This is the second consecutive extremely dry June through September since the 2000 total of 8.47 inches was the seventh driest period on record. In fact, four of the ten driest June through Septembers have occurred since 1992.

      The overall statistics, reflecting the extremely wet spring, still show Saint Cloud as being more than one and a quarter inches above normal. However, most areas are showing the stress of above normal temperatures and well below normal rainfall since mid-June.

      September 2001 in Saint Cloud was a month of near normal temperatures despite some extremes of both colder and warmer weather. No temperature records were set in either direction. Despite some public surprise, the first frost on September 24th was only two days earlier than normal. The first frost was also the latest in the past 5 years, including all three warm winters of 1997-1998 through 1999-2000. The first 28-degree temperature on September 25th was about two weeks early. However, the last sub-28 degree temperature was 10 days earlier than normal, so both growing periods were above normal. However, the lingering cloudy, rainy weather into mid-June did produce a delayed start to the growing season.
