Last night(November 5, 2017), at 1:48 AM CDT, a squall line moved through western TN. There was strong wind and heavy rain, but no lightning and thunder. Is there such a thing? I’m thinking of two possibilities: 1. The squall line was all nimbostratus. (Not likely at all) 2. Cb clouds produced no lightning or thunder. (Not likely either) Can someone explain what happened? I searched through the internet but couldn’t find anything.
