A monthly electronic newsletter summarizing Minnesota's climate conditions and the resulting impact on water resources. Distributed on the first Thursday of the month.

What happened in September 2014:

  • September precipitation totals were generally below-normal across most of Minnesota. Monthly rainfall totals fell short of historical averages by one to two inches in most locations. Isolated pockets of relative wetness were reported in a few locales.
    [see: September 2014 Precipitation Map  |  September 2014 Precipitation Departure Map  | September 2014 Climate Summary Table]
  • The most notable heavy rain event of September occurred on the 3rd and 4th when slow moving thunderstorms dropped three or more inches of rain, along with damaging hail, on some central Minnesota counties.
    [see: Heavy Rain: September 3-4]
  • Average monthly temperatures for September in Minnesota were very near historical averages. Cool temperatures mid-month were counterbalanced by a late-month warm spell. Extremes for September ranged from a high of 89 degrees F at Amboy (Blue Earth County) on the 4th, to a low of 25 degrees F at International Falls on the 13th. Many corn and soybean fields in central and southern Minnesota were affected by frost during the morning hours of the 13th. Mid-September frost is quite uncommon in these areas.

Where we stand now:

Future prospects:

  • The October precipitation outlook leans towards above-normal conditions across Minnesota. Normal October precipitation ranges from one and one-half inches in northwestern Minnesota, to over two and one-half inches in portions of northeastern Minnesota.
    [see: Climate Prediction Center 30-day Outlook  |  October Precipitation Normal Map]
  • The October temperature outlook tilts towards below-normal conditions throughout Minnesota. Normal October high temperatures fall from the low to mid-60s early in the month, to the upper 40s by month's end. Normal October low temperatures drop from the low 40s early in the month to near 30 by late October.
    [see: Climate Prediction Center 30-day Outlook  |  October Temperature Normal Map]
  • The 90-day precipitation outlook for October through December offers equal chances of below-normal, near-normal, or above-normal conditions in all Minnesota counties. The October through December temperature projection favors above-normal conditions.

  • The National Weather Service produces long-range probabilistic river stage and discharge outlooks for the Red River, Minnesota River, and Mississippi River basins. These products address both high flow and low flow probabilities.
