I know what your talking about Cook, I could feel it driving into it.
I have a broken window in the back of my truck and the draft coming in got really cold all the sudden, it got really foggy and the snow was hammering down. It was like hitting a wall.
By the time I got home, it dropped 15 deg.
About 35 min drive from Booneville and Marshall!!
And my wife says her knees are killing her, she's a pretty good barometer too.
