This loop of GOES-11 10.7 micrometer longwave InfraRed (IR) imagery shows the development of convection along and ahead of a cold front that was moving southeastward across the region. Periods of very cold cloud tops (-70 C, red enhancement) are evident, along with intermittent "Enhanced-V" cloud top signatures (which often indicate convection that is producing or about to produce tornadoes, large hail, or damaging winds).
