Helpful rains arrive:With the agricultural planting season now fully underway, some helpful rains began to occur this week following a dry start to the month of April. Up until the rains came, rapid planting progress was made, with earliest ever planting of sugar beets across the state. Also corn was being planted at a robust rate and may be near 50 percent completed by next week. Many northwestern Minnesota observers reported 0.75 inches to over an inch of rain, while southwestern areas received from half an inch to nearly 1.5 inches of rain (Luverne reported 1.64 inches). Elsewhere amounts generally ranged from a quarter inch to a half inch of rainfall. Though most observers still reported below normal rainfall for the month so far, rainfall is expected to average above normal for the balance of the month and will add to soil moisture recharge.
New Seasonal Climate Outlooks:The NOAA Climate Prediction Center released new seasonal climate outlooks on Thursday this week (April 21). The outlook for May, June, and July calls for temperatures across the Great Lakes Region, including Minnesota to be above normal, a trend that has been prevalent for well over a year now. The outlook for precipitation calls for drier than normal conditions to prevail in northeastern Minnesota, and equal chances for above or below normal values across the rest of the state.
Weekly Weather Potpourri:NOAA announced last week that a next generation Geostationary Operational Environmental Satellite, GOES-R will be launched in October of this year. It will provide enhance satellite data and observations for National Weather Service meteorologists, with better spatial and temporal resolution of measurements and broader coverage of the Western Hemisphere.
The National Snow and Ice Data Center (NSIDC) reported last week on the rapid loss of ice caps on Ellesmere Island in the Arctic Region of Canada. The loss of ice has been remarkably fast in recent years and is very evident in satellite imagery.
The Washington Post reported on a study by Knox College in Illinois which was a survey of attitudes towards creepiness. Over a 100 respondents were asked to rank several professional occupations in regards to creepiness. The creepiest occupations were clown, taxidermist and sex shop owner. Those ranked as least creepy were farmer, teacher, and professor. The least creepiest occupation? Meteorologist!
A recent paper published in the journal Nature documents suggests that worsening weather across the United States as a result of climate change may in the end provide the strongest motivation to do something about climate change. Areas of the country which currently experience a high percentage of pleasant weather, may see more unsuitable weather conditions prevail in the future, which will drive some changes in demographics.
Tropical Cyclone Fantala in the Southern Indian Ocean will bring high seas, strong winds, and heavy rains to the northern parts of Madagascar this weekend. It was producing sea waves near 30 feet and winds up to 105 mph on Thursday of this week. Elsewhere Tropical Cyclone Amos in the South Pacific Ocean will bring high seas, strong winds, and rain to portions of Pago Pago in American Samoa this weekend. It was already producing sea waves of 25 feet and winds up to 90 mph.
A recent paper published in EOS asked the question “Are U.S. states prepared to manage water in a changing climate?” This study of five states concludes the answer is emphatically No! Though MNRE effort has been directed in recent years to managing water resources, yet greater effort is needed according to this study.
MPR listener question:Now that we have apparently put the snow season in the rear view mirror, can you tell me which places in the state had the most snowfall for the season of 2015-2016?
Answer:Most climate observers around the state reported below normal values for the past snow season. The Twin Cities for examples reported just 36.7 inches, over 17 inches below normal. The exceptions were in northeastern and southwestern Minnesota counties where many observers reported above normal snow seasons. Some of these from the northeast included: Gunflint Lake (Cook County) with 83.9 inches; Ely (St Louis County) with 84 inches, Tower (St Louis County) with 75 inches; and Isabella (Lake County) with 120.6 inches. Some from the southwest included: Lake Wilson (Murray County) with 59.7 inches; Pipestone (Pipestone County) with 59.8 inches; Worthington (Nobles County) with 54.9 inches; and Lakefield (Jackson County) with 56.5 inches. Snow cover is gone across the state except for portions of Lake and Cook Counties in the northeast.
