9" snow on the ground as of Wednesday evening.
-3 F. low temperature Wednesday morning in the Twin Cities.
18 subzero nights so far this winter season in the Twin Cities (average for an entire winter is 28)
18 F. normal low for March 2.
17 F. reported high temperature in the cities on Wednesday.
34 F. normal high for March 2.
66.7" snow since December 1. It was the second snowiest "meteorological winter" since 1891. Only 1966-1967 was snowier in the Twin Cities.
Policies require a 30 day waiting period before becoming effective. And flooding typically begins sometime in March or early April - for central and southern Minnesota and west central Wisconsin.Being prepared for a flood can not only help keep your family safe, it can also help minimize potential flood damage and reduce the costs of recovery. Many people ignore the risks of flooding, assuming they aren’t in a flood zone. While some areas are more prone to flooding than others, the reality is, floods are America’s #1 natural disaster and can happen anytime, anywhere. In fact, 90% of all natural disasters in the United States involve flooding. Additionally, the risk level of a particular area can change over time. New development, changes in levee classification, and environmental changes can alter the impact of flood waters on an area.
Flood Insurance in the United States is provided through the National Flood Insurance Program (NFIP). Policies require a 30-day waiting period before becoming effective. However, snowmelt flooding, heavy rainfall downpours, and flash flooding can occur with little warning. Even where flooding occurs more regularly and slowly, thirty days may be too long.

Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:
Weather modification? Not a chance. These storms are too vast for any human intervention or cloud seeding to have a prayer. Any company foolish enough to tinker with Mother Nature on a grand (synoptic) scale would be made up entirely of lawyers.
A coating of snow may fall today, no big deal on the highways. A much more formidable storm is brewing for early next week; 1-2" Sunday-Monday, but Tuesday looks like the main event as a big, sloppy storm tracks just to our south. Over 6" may fall, with a potential for 10-12" nearby.
Investigating Droughts And Maya Collapse. What killed off the (highly advanced) Mayan civilization? An interesting article from the New York Times: "An important component of our research is the study of the past environment and climate changes. A team of Japanese geologists and plant scientists addresses this by analyzing lake sediments as part of the project financed by the Japanese Ministry of Education, Culture, Sports, Science and Technology and directed by Kazuo Aoyama. In contrast to archaeologists, who usually specialize in specific geographic regions, those researchers are global travelers. They have been taking lake cores from Japan, China, Cambodia, Bali, Easter Island, Egypt and Peru. The team is known for its uncanny ability to find annual varves and for its innovative analysis. Under specific conditions of seasonal change, lake hydrology and the anoxic water that prevents bottom-dwelling critters from disturbing sediments, thin laminations of deposits may form yearly in lake bottoms. These annual varves are time capsules of environmental data. Through the analysis of geochemistry, isotopes, pollens, diatoms (a group of algae) and other remains in each layer, scholars can trace changes in precipitation, vegetation, agricultural practice, erosion rates, volcanic eruptions, etc., in a yearly resolution."
Global Warming Affecting Food Chain In Arctic Ocean. It's been a strange winter in the Arctic - temperatures running 10-20 degrees above average in some (far) northern latitudes. Here's an article from signonsandiego.com: "The huge life-giving phytoplankton bloom that forms in the Arctic Ocean each summer is occurring progressively earlier, a change that might hurt the marine food chain, says new research from the Scripps Institution of Oceanography. Researchers attribute the shift to global climate change, which they say causes Arctic ice to thin and melt, creating gaps where the bloom can briefly flourish. The shift is most notable in Hudson Bay, Foxe Basin, Baffin Sea, off the coasts of Greenland, in the Kara Sea and around Novaya Zemlya, Scripps says. “It’s not clear if fish will adapt to the change, and whether it will disrupt critical life-cycle stages such as egg hatching and larvae development,” said Mati Kahru, the SIO oceanographer who led the study. “The bloom provides a major source of food for zooplankton, fish and bottom-dwelling animals. The advancement of the bloom time may have consequences for the Arctic ecosystem.”
Water Woes: Demand To Outstrip Supply By 40% In 20 Years. A story from the Times of India: "LONDON: The demand for water in the world may exceed its supply by 40% within the next 20 years due to global warming and population growth, scientists have warned. As looming water shortages threaten agriculture, industry and the communities, a new way of thinking about water is highly essential, suggested the experts who gathered at an international meeting in Canada. They warned that in the next two decades, a third of world population would get only half the water they require to meet basic needs, the Daily Mail reported. Around 300 scientists, policy makers, and economists attended the international meeting in Ottawa hosted by the Canadian Water Network (CWN) in the run-up to the World Water Day."
