35 years ago on June 21, 1987, a tornado made its way through a mobile home park in Novi Michigan. The tornado, damaging around 55 homes, killing one, and injuring six more, touched down at the Chateau Estates mobile home park.

The Allied invasion of the Nazi-held French coast at Normandy is widely regarded as one of the most important military operations in history.

Ninety-eight years ago, the single worst tornado in United States history occurred.

When this cold air flows over the warmer Great Lakes, an unstable atmosphere develops -- we meteorologists call it the "Great Lakes Aggregate."

The start of 1999 around the Great Lakes region and Southern Ontario was one to remember.

DETROIT – Strictly from a historical standpoint, Jan. 21 is a most intriguing day for Detroit weather records. You see, on Jan. 21 in 1984, we set a record low of -21 degrees (-29 degrees Celsius), which officially stands as the coldest recorded temperature in Detroit weather history. Our National Weather Service office has the old books that the daily weather statistics were hand-recorded in, and Detroit weather records date back to 1870. But once that book was lost, all records set from 1870 to 1873 were disqualified. I maintain an Excel spreadsheet with all of Detroit’s weather records, including some oddball records not typically kept.

On Nov. 17, 2013, more than 70 tornadoes moved across part of the Midwest, impacting seven states including Michigan.

But how much rain fell, and how historic was it? That amount of rain falling at Midland in a forty-eight hour period is statistically expected to occur only about once every twenty-five years, so the fact that this rain fell in thirty-six hours means that it was a 25-to-50 year event. Adding insult to injury is that this rain came after another inch to inch-and-a-half of rain fell last Thursday into Friday. I've told you many times in the past that global warming does not CAUSE individual weather events. In this case, extreme precipitation events are definitely occurring more often, and there is a very simple reason why: as Earth warms, more ocean water is evaporating into the atmosphere.
