A movie was created using infrared and visible data from NOAA's GOES-13 satellite from March 17 to March 19 at 1740 UTC (1:40 p.m. EST). The GOES satellite animation shows convection (rising air//thunderstorm development) exploding around 0245 UTC on March 19 (10:45 p.m. EST on March 18). In the satellite movie, the strong front comes together and resembles an upside-down arrow at the end of the animation on March 19. Credit: NASA//NOAA GOES Project
