Meteorologist · Professor · Manager

Weather, probability, and the code in between.

I lead the Science and Mission Integration Division at the NOAA Storm Prediction Center. I am also an Assistant Professor of Natural Science at Oklahoma Baptist University, where I hold the W.B. Blackstock Family Chair of Science Education. I write about forecasting, forecast verification, and the data behind both.

Views here are my own, not those of NOAA or the National Weather Service.

At the Storm Prediction Center

My division moves new science and technology into SPC forecast operations, and it keeps the computing systems behind those forecasts running.

In the classroom

At Oklahoma Baptist University I teach Earth Science, Environmental Science, College Physics, and two courses in data science.

At the keyboard

I build tools for seeing weather data, from a desktop radar app to a live weather dashboard for the OBU campus.

Projects

GRLevelX · hourly data

Mesoanalysis placefiles

Fields from SPC's hourly surface objective analysis, such as CAPE, shear, and STP, packaged as placefiles to overlay on radar in Gibson Ridge software.

Web · live data

OBU Weather Awareness

Live radar, warnings, and watches for the campus in Shawnee, Oklahoma.

Web · OBU courses

Course labs

Simulations and hands-on labs for the courses I teach at Oklahoma Baptist University.

Earlier work

  • Founder and initial developer of SHARPpy, a Python port of SPC’s SHARP sounding analysis program. It is no longer maintained.
  • Added county boundaries to Basemap, the map toolkit for Matplotlib.
  • Bug fixes for Matplotlib, the Python plotting library.
