John was born in Baton Rouge, LA, and grew up near Birmingham, Alabama. As a teenager, his family moved to Madison, Wisconsin, and later to a small town in northeast Iowa. John traces his early interest in weather to the difference in climate between Alabama and Wisconsin. He is a graduate of Iowa State University with a degree in meteorology. Like any meteorologist, John is intrigued by extremes of weather, especially arctic air outbreaks and winter storms. John has been known to say he prefers his summers to be hot but in winter, he prefers the cold. When away from work, John enjoys long-distance running and reading. John has been a meteorologist at WDAY since May of 1985.

July and August are our least windy months of the year, but as summer begins to drift into fall, the weather will turn windier as it turns cooler. Wind is officially measured at 10 meters, or about 33 feet, above the ground. Although this is far higher than most of us experience the wind, 10 meters is used because the readings are less affected by local turbulence, and so of greater use to forecasters and airplane pilots. There are three parts to a wind recording. First, there is the direction. This is the direction the wind is coming from.
Midnight and still 80 degrees. You knew it would still be in the 70s in the morning. Remember those sticky summer nights spent on sweat-soaked sheets? You were too hot to sleep so you'd lie awake listening to the constant drone of the box fan in the window. It can be hard to sleep without air conditioning in such weather, but in some summers, including this one, most of us can manage fine with just open windows. This June brought very few days (or nights) with high humidity and there have been none so far in August.
The first half of August has been cool. Every day but one has been cooler than average with the exception of Aug. 8 which, with a high of 85 and a low of 45, was exactly average. Through yesterday Tuesday, Aug. 15, the average daily temperature so far in August is 66.9 degrees which is about 4 degrees cooler than average. If the weather remains cool enough for August to finish with a cooler-than-average mean temperature, it will be the first cooler-than-average month since May, which was a slim 0.1 degree cooler than average.
August, the final month of summer, is half over. Nights are longer and starting earlier. Days are perceptibly shorter than they were a month ago. It can be said that summer is on the wane, but it is premature to pronounce it dead. There have been 10 days all summer that have reached 90 degrees and there is still time for a few more. Historically, a few days of 90 degree weather have often occurred in late August and even as late as mid-October. But we should also expect those cooler days to begin happening more frequently.
(WDAY-WDAZ) The National Weather Service has issued its storm damage survey of last Tuesday’s storms. The most impressive storm produced four separate tornadoes along with a tremendous amount of additional straight-line wind damage as well as hail. A great deal of the straight-line wind damage occurred in a wide area to the southwest of the ongoing mesocyclone. The first tornado from this supercell touched down northwest of Northwood and remained on the ground 4.5 miles with peak winds estimated at 90 mph.
If someone asks about April weather, what would you think of? A lot happens around here during April, weather-wise. It is the month when trees leaf out and when grass turns green. We usually experience our first 70 degree day of the spring in April. Most years, we get our final few flakes of snow as well.
The weather is settling down for the rest of this week after a duo of smallish weather systems have produced scattered snow, strong wind, and icy roads in spots the past two days. The only concern drivers are expected to have the rest of this week is scattered icy stretches of road due to daytime snow melt being redeposited onto road surfaces at night and early in the morning.
(WDAY-TV / WDAZ-TV) A major winter storm remains a distinct possibility for the Christmas weekend. But icy roads are already a problem Tuesday night and Wednesday. Tonight, following a mild and sunny day, many roads have developed frosty conditions which is creating extremely icy stretches of roadway. Use extra caution as icy stretches may not be visible until drivers encounter them. Overnight, a few scattered snow showers are expected to produce a few areas of light snow accumulation.
