A good way to start an emergency preparedness kit is to have a NOAA Weather Radio (NOAA; National Oceanic and Atmospheric … Read more
Atmospheric gravity waves, known as undular bores, are waves in Earth’s atmosphere that often show up quite well on satellite and radar imagery. They are notorious for creating wave-like clouds, which clearly propagate as waves when viewed in rapid time-lapse photography. Low-level atmospheric stability is implicated in the formation of undular bores. Large static stability … Read more

What was a marginal day for severe weather ended up producing one of the most violent tornadoes of the 2016 season. We visited Chapman on Saturday, July 23rd, … Read more
Definition of Heat Index: The heat index is an estimate of how hot the air “feels” to the human body and provides a relative indication of potential health risks. Among others, the two primary factors in the heat index equations are temperature and water vapor (i.e., moisture/humidity). Humidity affects the efficacy of perspiration to evaporatively … Read more

Storm chasing is an emotional roller coaster. From operational field missions, to university research, and to the hobbyist and/or nature explorer, storm chasing consists of several thousand miles of driving for sometimes only an hour of action. Each Spring, scientists, meteorologists, hobbyists, and explorers, venture out to the Great Plains to seek some of the atmosphere’s … Read more
Currently at Dallas/Fort Worth (DFW) The temperature is: DFW’s heat index is: °F Current Conditions Around N. TX How many days until fall? It’s pretty much a given that summertime in North Texas will be hot. However, there is a fine line between “hot” and dangerously hot. In other words, “only” a few degrees can … Read more
