Significant Drought Reduction:
May total rainfall is significantly above normal now for several Minnesota climate stations, including:
6.21" at Moorhead
5.07" at Georgetown
5.98" at Artichoke Lake
6.48" at Cass Lake
5.32" at Park Rapids
5.00" at Pokegama Dam
4.53" at Kabetogama
6.72" at Morris
6.61" at Montevideo
5.61" at Ottertail
5.22" at Collegeville
5.92" at Kimball

As a result of the wetter than normal May for many climate stations, the overall extent of drought in the state has diminished considerably. Severe drought which encompassed nearly 35 percent of the state landscape last week has completely disappeared, while the area of the state in moderate drought declined from 92 percent of the state landscape to just 50 percent this week. These figures can be viewed at the Drought Monitor.
Cold Temperatures Prevail May 18-20:
May 19 and 20 brought frost to many areas of the state, and in some cases injury to emerged crops. Many climate stations reported morning lows in the upper 20s to lower 30s F. Thorhult (Beltrami County) reported a new record low of 26°F, Rosemount a record low of 29°F, and Collegeville reported a record low of 31°F.
May 20th brought some additional frosty temperatures to some locations and some new record setting low temperatures including 23°F at Isabella (tied record low from 1986), 25°F at Crane Lake (tied record from 1967), 27°F at Kabetogama, 25F at Orr, 40°F at Minnesota City, and 44°F at La Crescent.
Farmers and crop consultants were assessing frost damage to crops, mostly scattered field damage to soybeans and sugarbeets that had been planted early.

Past Weather Features:
One year later, by far the hottest May 22nd in state history occurred in 1925. On that date over 40 Minnesota communities saw the thermometer reach or surpass 90° F, and three southern Minnesota communities reached 100°F.
Thunderstorms and persistent rain brought a halt to the planting season over May 22-25, 1946. Many observers reported 2-4 inches of rainfall, saturating soils and flooding some county roads. Five consecutive dry days, including Memorial Day, allowed farmers to finish planting by the end of the month.
May 22, 2001 brought snow to northern Minnesota, including the communities of Big Falls, Roseau, International Falls, and Little Fork. It was short-lived as temperatures warmed into the 50s and 60s F the very next day.
