November 28, 1983: Widespread snowfall occurs across much of central Minnesota with snowfall totals at or above 1 foot in many areas. A record 15 inches fell in Gaylord and 14 inches fell in Farmington.
November 28, 1960: A major storm produces near hurricane force winds on Lake Superior, with 20 to 40 foot waves on the lake. Erosion and damage occurred on the North Shore.
"Thunderstorm Asthma" Hospitalizes 8,500 in Australia
I thought I had seen everything. I was wrong.
6 people are dead, thousands temporarily hospitalized when moisture within a thunderstorm hitting Melbourne, Australia combined with pollen to trigger severe asthma attacks. A third of patients who suffered these attacks reported never having asthma before. The storm broke up grass pollen into tinier fragments, penetrating deep inside people's lungs. These events are rare, but similar cases of thunderstorm asthma have been reported in Britain, Italy, Canada and the USA.
Natural and man-made pollutants lead to twice as many premature deaths in the USA as auto accidents; over 70,000/year. People suffering from COPD and asthma are most at risk. Some of the most severe cases of air pollution strike in late fall, when warm air aloft can trap bad air near the ground.
Rain showers linger today; the atmosphere marginally cold enough for light snow later this week, but temperatures near 32F will keep roads wet during the day.
I don't see any big storms, but NOAA's GFS model hints at the first subzero nighttime low at MSP within 2 weeks.

The model is forecasting colder than normal temperatures for much of the Eastern United States with warmer than normal temperatures for the Western United States. The model uses October Siberian snow cover, sea level pressure anomalies, predicted El Niño/Southern Oscillation anomalies, observed September Arctic sea ice anomalies, and the predicted winter value of the Pacific Decadal Oscillation. October Siberian snow cover advanced at an above normal rate during the entire month. This is an indication of an increased probability of a weakened polar vortex or a sudden stratospheric warming and a predominantly negative Arctic Oscillation during the winter, and cold temperatures, especially east of the Mississippi. This is the most recent forecast using the full monthly values for snow cover and sea level pressure anomalies."

Full Speed Ahead: Shipping Plans Grow As Arctic Ice Fades. Here's an excerpt of a head-shaking article at Yale Environment 360: "...Russia is farther ahead than any other country in exploiting Arctic shipping opportunities. It has more icebreakers by far than any other nation — 40 — and more Arctic ports. (Canada and the United States have no significant ports on the Arctic Ocean.) To further boost the development of new shipping routes, Russia’s State Commission on Development of the Arctic Regions convened in Moscow last April to establish a single company that will oversee all logistical operations in the Arctic region and coordinate the activities of various levels of government..."

Perils of Climate Change Could Swamp Coastal Real Estate. Here's a link and excerpt from The New York Times: "Real estate agents looking to sell coastal properties usually focus on one thing: how close the home is to the water’s edge. But buyers are increasingly asking instead how far back it is from the waterline. How many feet above sea level? Is it fortified against storm surges? Does it have emergency power and sump pumps? Rising sea levels are changing the way people think about waterfront real estate. Though demand remains strong and developers continue to build near the water in many coastal cities, homeowners across the nation are slowly growing wary of buying property in areas most vulnerable to the effects of climate change..."
