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.

A wall cloud with a tail tricked many western Minnesota residents into thinking there was a tornado Monday night. But the parent thundershower was too weak to generate a tornado. Instead, the weakly rotating updraft of the thundershower formed a low-hanging, rotating wall cloud. Then a condensation inflow tail developed, which was shaped liek a sideways funnel. But it was not an actual funnel cloud. No tornado warning was issued because there was no danger of a tornado. Doppler radar revealed the weak rotation and structure.
Spring is brush fire season across our region. Dry weather is often blamed for this, but the problem is that winter has left us with so much kindling.
(WDAY-TV/WDAZ-TV) Winter weather is invading the region for the start of the Easter weekend. Portions of the area are under a Winter Weather Advisory tonight. A Winter Storm Watch covers most of the region Friday night for a second weather system. Tonight, scattered snow showers are the problem. Because of the showery nature of the snow tonight, amounts will vary greatly and will defy any attempt at a simple snow total map. Some areas won't get much at all. Some spots will get a few inches. It all depends on where the heaviest snow showers track.
(WDAY/WDAZ) Another round of heavy, wet snow threatens much of the region. Heavy snow is expected to begin early Friday across western North Dakota, spreading into the Devils Lake and Jamestown areas by mid afternoon, and into the Red River Valley Friday evening and Friday night.
(WDAY/WDAZ) After a week of build-up, a major March storm has finally arrived in the Dakotas and Minnesota. The biggest forecast challenge with this storm is the temperatures, which are likely to vary within a few degrees of 32 much of the day Monday. If it is cold enough, heavy snow accumulation is likely. Places that remain a few degrees too warm will experience lighter and more slushy accumulations. A period of sleet or freezing rain is also possible for some parts of the area.
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.
