When the new GOES R satellite is launched in two years (unless budget cuts intervene), we will have high resolution one minute images available in real time during events like this. The GOES-R will have the capability to do one minute images over two spots at the same time. Not just in visible wavelengths, but in many different channels in the infrared as well, and in higher resolution.
Satellite data will become near real time, like radar is now during severe weather events.
