So far, so good. It got eerily quiet. Now the wind is gusting a bit. Lightning, with thunder in the distance. I am thinking I will see some hail, winds ( downburst) and heavy rain. Be safe out there. Anything and everything can pop up. Be weather wary. Larry Cosgrave nailed this early this afternoon. He was really worried about our area tonight.
