Thursday, November 6, 2008

ST. CLOUD, Minn. – According to St. Cloud State University Meteorologist Bob Weisman, this season’s first hard freeze wasn’t until Oct. 21, leading to the longest growing season since 1970.

Weisman’s October St. Cloud weather summary also reported moderately warm, wet weather conditions throughout the month. Modest rainfall eased dry conditions in most of Central Minnesota.

  •  The first frost occurred Oct. 4, one of the latest frosts on record.
  • The first hard freeze was Oct. 21, one of the latest 10 percent on record.
  • October rainfall totaled 2.6 inches, 0.36 inches above normal.  Oct. 5-13 saw 79 percent of that rain.
  • Nearly half of the month’s rain fell Oct. 7, at 1.24 inches.
  • By mid-October, most drought conditions in the St. Cloud area disappeared, though moderate drought continues in southeastern Minnesota.
  • The second half of October saw cool, dry conditions as winds headed northwest.
  • The average temperature was 47.1°F, 1.8°F above normal.
  • The first wet snow fell Oct. 26, as winds exceeded 47 mph.
  • Lows dropped to the 20s Oct. 27, a three-day trend producing frost as far south as north central Florida.
