 shows extreme drought has returned to the Twin Cities and parts of southern Minnesota. 

The extreme drought area (in red above) covers most of the central and southern Twin Cities southwest along the Minnesota River to the northeast of Mankato near St. Peter. Extreme drought also covers parts of southwestern Minnesota centered on Lyon County and Marshall. 

Severe and moderate drought areas surround the extreme drought zone. And the total land area in Minnesota that is now abnormally dry or in drought status is now 77.4 percent. That’s up from just over 54 percent last week.

Ponds, rivers, lakes and other surface waters are drying up quickly in the dry and warm late summer and autumn weather patterns. 

 is at its lowest level since the drought of 2012 according to this week’s drought monitor update.

The forecast for the Upper Midwest shows a dry bias for the next one to two weeks. The upper-air pattern across North America favors mostly northwest flow for Minnesota. That will bring us some cooler air invasions from time to time, but likely very little rainfall. 

Both the European Centre for Medium-Range Weather Forecasts and American medium-range forecast models suggest little to no rainfall for Minnesota through at least the next 10 days. 

The National Oceanic and Atmospheric Administration’s Global Forecast System model total precipitation output into Oct. 22 suggests most of Minnesota could stay dry.

With no significant rainfall in sight, Minnesota’s drought is likely to deepen further in the next month. If we don’t flip the pattern into wet mode before the freeze-up in November, we may be dealing with serious drought issues next spring as we approach the 2023 growing season.
