Preliminary Climate Summary for September

Preliminary Climate Summary for September: Mostly warmer than normal weather dominated our September weather with nearly two-thirds of all days bringing above average temperatures. Overall, most climate stations will report an average monthly temperature from 2°F to 4°F above normal. Extremes for the month ranged from 99°F at Lamberton (Redwood County) on the 21st to 21°F at Brimson (St Louis County) on the 28th. Over 50 climate stations reported at least one day with a maximum temperature of 90°F or greater. Within the state climate network during the month 49 daily high maximum temperature records were tied or broken. Despite the overall warmer than normal month, at least 70 climate stations reported frost over September 28-29, including as far south as Austin (Mower County). About a hundred climate stations have yet to report first frost. Rainfall was less than normal across the state except for some northeastern and north-central counties.

Warm and Dry Start to September

Warm and Dry Start to September: Temperatures so far are averaging 3 to 5 degrees warmer than normal around the state over the first 8 days of the month. Seventeen climate stations have reported at least one day in the 90s F so far this month, while only Brimson (St Louis County) has reported a frost so far. Until Friday of this week rainfall has been scarce to absent in most places. Only a few spots have been grazed by spotty showers so far, mostly in southeastern Minnesota. The overall pattern of dryness and drought within the state has remained fairly constant since the last week of August. Amounts from Friday’s rain showers and thunderstorms are expected to range from 0.50 inches to 1.50 inches in many areas, welcome moisture for most areas of the state. Unlike earlier months this year, winds have been relative mild so far this month, with very few wind gusts of 30 mph or greater and a number of hours of calm.

Climate Summary for August of 2022

Climate Summary for August of 2022: Most climate observers reported a mean monthly temperature that was very close to normal, or in some cases 1°F to 2°F above normal. Extremes for the month ranged from 101°F at Marshall (Lyon County) on the 3rd (which was a new daily record high for them) to 39°F at several northeastern climate stations on the 11th. Adding the August temperature statistics to those of June and July shows that most areas of Minnesota recorded a mean summertime (Jun-Aug) temperature that was 1 to 2°F above normal. On a statewide basis, 11 of the last 12 summers have been warmer than normal across Minnesota. Most areas of the state reported above normal rainfall for the month of August, except for some observers in northwestern, west-central, and southwestern Minnesota. Wetter areas of the state were generally in eastern counties. In fact some observers in Houston, Washington, Steele, Fillmore, Dakota, Winona, and Olmsted Counties reported 7 to 9 inches of rainfall

The Wettest Night at the State Fair Remembered

The Wettest Night at the State Fair Remembered: Forty-five years ago, August 30, 1977, is long remembered by Minnesota State Fair goers as a traumatic and very wet evening. The weather became cloudy hour by hour and the dew point rose gradually until it was an uncomfortable 70°F by early evening. Temperatures were in the 70s F with moderate south winds and a chance for thunderstorms in the forecast. As the Grandstand show got underway it began to rain, at first lightly, then heavier. (I think Mac Davis was the featured entertainment). Between 8 and 9 pm the rainfall intensified, and many began to leave the Grandstand as well as the Fairgrounds. Between the hours of 9 and 10 pm nearly 3 inches of rain fell, flooding the streets and sidewalks. Visibility during the heaviest rainfall was just a few feet, making it difficult to find your way to the Fairground exits. There was widespread flooding all around the Twin Cities, especially from the Fairgrounds south toward Bloomington an

Many areas of the state saw 1 to 2 inches of rainfall on August 16, 17, and 18. Some long-term climate stations even reported daily record rainfalls, including: Big Falls (Koochiching County) with 2.40 inches on the 16th Winnibigoshish Dam (Itasca County) with 3.11 inches on the 17th And on the 18th new record rainfalls were reported from Mora (Kanabec County) with 2.14 inches, Wright (Carlton County) with 2.70 inches, and Cambridge (Isanti County) with 4.32 inches. With the heavier rains in northern Minnesota this month, some Minnesota communities like International Falls, Chisholm, Thorhult, Tower, and Grand Portage remain on a pace to record one of their wettest years in history. Overall total rainfalls of 3 inches or greater have fallen this month over about 20 to 30 percent of the state helping to hold the drought areas in check. About 12 percent of
