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.

You hear it all the time. What's the wind chill? Can you imagine going through a winter without this numerical fixation? Did you know that the wind chill index came into weather reporting vogue during the early 1970s. Prior to that, we could only add the term "windy" to our temperatures. The original wind chill formula was developed by the U.S. military during the 1950s for Arctic maneuvers. But their science was hastily done and the values it gave were ridiculously low. During the 1980s, many meteorologists began to argue for a new index based on more accurate experimentation.
(WDAY-TV/WDAZ-TV) It won't be the kind of storm that shuts down roads, but snow coming Wednesday and Wednesday night will have impacts for travellers. Snow will begin Tuesday night over western North Dakota, spreading into eastern North Dakota and western Minnesota Wednesday, continuing Wednesday night. The snow will be light and airy but wind will be light to moderate, so no significant drifting is expected. The main impacts will be slick roads and vehicle snow fog.
(WDAY/WDAZ TV) The first winter storm of the season is expected to hit the region Thursday and Thursday night. This will be as much a wind storm as a snow storm although any snow accumulation will become a problem due to the fierce wind expected.
(WDAY/WDAZ TV) Severe thunderstorms are likely this Tuesday evening and night across the eastern Dakotas and western Minnesota. A strong upper level low pressure area approaching from the Pacific Northwest is causing strong southwesterly winds in the upper levels of the atmosphere. At the surface, muggy conditions and a strong southeast wind is undercutting this upper flow, creating an explosive storm situation. The moist air will be forced upward and the wind structure will create an environment in which strong, rotating storm updrafts are likely.
(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.
(WDAY-TV / WDAZ-TV) The good news is that travel conditions should be fairly good through Christmas Eve. The bad news, for travelers anyway, is that a combination of snow, sleet, freezing rain, rain, and strong winds could make moving around very difficult by sometime Christmas Day into Monday.
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.
