In southern Wisconsin, the average temperature for the summer months — defined as June, July and August — was near normal.
Rainfall was a different story. All of southern Wisconsin had summer accumulated precipitation of more than 16 inches, or 125 percent of normal. For much of the region, accumulated precipitation in August was more than 7 inches, which is more than 175 percent of normal. Continue reading
Our rainy Friday was arguably the first storm, or cyclone, of the autumn/winter season. Though it will surely be followed by more powerful examples, you may well have wondered how do such storms come to be?
That has been the central motivating question in meteorological science for most of the past 100 years. During that time, meteorologists have learned a great deal about how these mid-latitude cyclones are formed. Continue reading
During the last week of July — the 25th through 31st — the temperatures across Wisconsin were 1 to 4 degrees below normal. In fact, much of the Midwest was cooler than normal.
The cooler temperatures resulted from a Canadian high-pressure system that settled over the central U.S. during that final week of July. Continue reading
The welcome respite we just enjoyed from the prolonged heat and humidity of late June and July may have inspired fond thoughts of autumn to many in southern Wisconsin.
Of course, there is still a lot of summer left, though we have just passed the climatologically warmest day of the year in Madison – July 14/15. This closely coincides with the date on which air with a temperature of 23 degrees at about 1 km above the surface shrinks to its annual minimum extent. Continue reading
Beginning on Saturday, Madison has experienced two straight days in May at or above 90 degrees for the first time since 1991 and for only the third time in nearly the last half-century (the others were in 1975 and 1978).
What’s more, the forecast is for temperatures to soar into the mid-90s again today and Tuesday which, if it happens, would be the first time since at least 1971 (and perhaps in its history) that Madison has had four consecutive May days at or above 90. Continue reading
