Continued Record Dry Spell

Continued Record Dry Spell: Our record dry spell continues on a statewide basis. The average total precipitation across the state since August 31st is just 0.55 inches, about 3.25 inches below normal. So far this month only a few showers have occurred over northern Minnesota on October 5-6. Observers in Carlton, St Louis, Koochiching, Cook, Lake, Beltrami, Lake of the Woods, Roseau, and Cass Counties reported some measurable amounts of rainfall, but mainly less than a tenth of an inch. The impact of the dry spell has been exacerbated by temperatures that have averaged 5°Fto 8°F above normal. This combination has produced unusually high evapotranspiration (loss of water vapor from the landscape and area lakes), so consequently Minnesota is showing signs of the dryness in terms of declining lake levels, stream flow, and vegetative stress. This week’s U.S. Drought Monitor shows that 97 percent of the state is abnormally dry, 69 percent is in at least Moderate Drought, and 20 percent (

Dry Spell Continues With Frosts

Dry Spell Continues With Frosts: After a record-setting warm and dry month of September, October has begun warm and dry as well, with zero rainfall reported across 95 percent of the state. Speaking of rainfall, September was the driest in history for several long-term climate stations in Minnesota, including: Minneota (Lyon County) with 0” Canby (Yellow Medicine County0 with a Trace Alexandria (Douglas County) with .03” Melrose (Stearns County) and Elk River (Sherburne County) with .05” MSP with .06” Park Rapids (Hubbard County), Red Wing (Goodhue County), Windom (Cottonwood County) with .10” Brainerd (Crow Wing County) with .11” Marshall (Lyon County) with .15” Jordan (Scott County) with .16” Two Harbors 7NW (Lake County) with .17” Madison (Lac Qui Parle County) and St Peter (Nicollet County) with .18” Ottertail (Otter Tail County) with .19” Overall, the statewide average rainfall was 0.55 inches for September, a record low amount. The consequence of this prolonged dry spell contin

Preliminary Climate Summary for September of 2024

Preliminary Climate Summary for September of 2024: Warm and dry are the succinct words for this September in Minnesota. This will be the first time in history that the statewide average September temperature will exceed 64°F, surpassing the previous warmest September of 2015 (63.8°F). Most climate stations will report an average monthly temperature that is 5°F to 8°F above normal. Counties of northwestern and north-central Minnesota were nearly 9°F warmer than normal. Extremes were 92°F at Granite Falls (Yellow Medicine County) on the 16th and 26°F at Ely (St Louis County) on the 7th. Within the state climate station network, there were 48 record daily high temperatures and 73 record daily warming minimum temperatures. Many nighttime temperatures remained in the 60s F, and even a few nights never went below 70°F at places like Milan (Chippewa County) and Alexandria (Douglas County). September was drier than normal in almost all areas of Minnesota, except for the far northern sec

Warm and Dry September Continues

Warm and Dry September Continues: The first 19 days of September have brought extraordinary warmth to the state. The average statewide temperature for this period is the 3rd warmest in history, trailing only 1931 and 1897. Most climate stations are reporting an average monthly temperature so far that is 5° to 8°F above normal. Many climate stations have reported 14-15 days with daytime temperatures in the 80s F, while climate stations in Yellow Medicine, Redwood, Lyon, and Lac Qui Parle Counties have reported 90°F. In addition, many nights have remained warm, with low temperatures in the 60s F. Dr. Kenny Blumenfeld of the Minnesota State Climatology Office offered more insights on these warm temperatures in a commentary posted on their web site this week. Over the last 20 days the statewide average rainfall has been less than a quarter of an inch, while many individual climate stations have reported less than a tenth of an inch. Parts of northern Minnesota received significant r

A Very Dry Two Weeks

A Very Dry Two Weeks: It has been a very wet year across the state of Minnesota, with many climate stations already reporting total precipitation for the year-to-date that exceeds their annual normal amount. So, the recent two-week dry period (nearly total absence of significant rainfall) has been quite unusual. In fact, statewide statistics show it has been the second driest two-week period or longer for the year so far. Statewide average precipitation low points in 2024: January 19-February 7 average of 0.06 inches (14 days) August 31-September 13 average of 0/08 inches (20 days) February 16-March 19 average of 0.16 inches (33 days) In addition, some of the lowest values of afternoon relative humidity for the growing season have been measured this week with readings in the 25 to 37 percent range. As a result, many gardens around the state have required some watering this week, along with other landscapes like golf courses. It appears that this situation will change significantly
