  Dr. Jana Houser, Assistant Professor, University of Ohio, Athens, OH
Dr. Houser is an atmospheric scientist specializing in the study of supercells and tornadoes.  Her work is predominantly observational, examining case studies of supercell thunderstorms and tornadoes using mobile and fixed location Doppler and polarimetric radar.  She is particularly interested in the rapid development and evolution of tornadoes and their nearby storm-scale features, and how topgraphy and fristion affect tornadoes.

Her past and some current research has focused on examining the evolution of rotation from which tornadoes develop, particularly trying to answer the question of whether tornadoes begin aloft or near the surface, and what the source of tornado-strength rotation is.

Mike Griesinger, Lead Forecaster, NWS Chanhassen, MN
Mike is a native of southwest Michigan and took his life long interest in the weather off to Central Michigan University, where he received a B.S. degree in 2004. Mike then traveled to Lubbock, TX, where he received an M.S. in Atmospheric Science from Texas Tech University in 2006. While at Texas Tech, he conducted a research project surrounding the topic of convective initiation along the dryline and also assisted research teams in the spring with investigating the RFD environment through the use of in situ observations using mobile mesonet equipment. Mike joined the National Weather Service as in intern in the fall of 2006 at the Atlanta office in Peachtree City, GA and joined the forecast team at the Twin Cities office at the beginning of 2009. Since coming to the Twin Cities, he has be an active participant in the Skywarn program, having taught several classes and updated the skywarn presentation given by the office.


Dr. Kenny Blumenfeld, Senior Climatologist, MN State Climatology Office, St. Paul, MN
Dr. Kenneth (“Kenny”) Blumenfeld focuses on climate change science, extreme events, and new climate monitoring networks for the Minnesota DNR State Climatology Office. One of his professional responsibilities has been to align the state’s agencies, communities, and citizens with up-to-date and scientifically accurate information about Minnesota’s changing climate. He also works part-time for Hennepin County Emergency Management, where he provides hazardous weather research and forecasting support. Outside of work, Kenny has made a documentary movie about Minnesota’s winters, frequently pursues “creative climate science” endeavors, and generally loves talking to Minnesotans about their weather..

  Dan Miller, Science and Operations Officer, NWS Duluth, MN
Dan Miller is the Science and Operations Officer at the National Weather Service forecast office in Duluth, Minnesota.
