Oh! my goodness I'm so glad you and your family are safe. I grew up in Oklahoma, so know how long those nights can be. we had beds in our shelter so the kids just crawled in and spent the night.
I still watch the storm clouds and have been gone from back there for 50 years. Move your sewing room to the basement then you won't have to carry so much down there.
God bless everyone that has to fear this distructive force of nature.
