I read you blogs frequently since you are closest to my area. We live in a low area and surrounded by trees, so no chance of seeing a tornado coming even during daylight. Lived in Oklahoma for a few years in the late 70's/early 80's, but never saw one there either. Been following the weather since i was old enough to remember. Just walked my dogs and would estimate gusts to 40.
Be aware of spinups . the area u are in right now is the low level jet kicking in ... the storm looks to cause 60 mph winds when they come thru in the next hr or so . be aware u are in a tornado watch , the kind of tornadoes that occur in this environment are usually with no thunder or lightning rain wrapped and hard to see at night and they are spinups usually in the line .. thanks for reading and stay safe and continue to follow us... I am east of roanoke va so i know va weather pretty well ... i used to live in southern nj . so i know the weather and severe weather is my specialty
