I've always found geographic visualizations of surface/mixed-layer CAPE models and other weather data to be incredibly interesting.
Here's a map featured by the Capital Weather Gang over at the Washington Post, during the June 12-13, 2013 derecho series in the Ohio Valley/Chesapeake Bay regions. It was created by WeatherBELL, which is a subscription service offering visualizations based on their proprietary technology.
Here's another map featured on the blog of Cliff Mass, a professor of atmospheric sciences at the University of Washington. This is an internal UW WRF model that is GFS-initialized.
I would like to know how I can take archived GFS or WRF data and visualize it on a map. Or even if that's possible (perhaps archived numerical data is only available to paid subscribers). What I would like to do is plot surface and upper-air readings to better understand the mesoscale setups for thunderstorms in the Pacific Northwest, where I live.
