See this sky??
At the time I took this yesterday the temp was 72 degrees. In a matter of four hours the temp dropped 50 degrees. For us here in Texas it's known as a "blue norther." In grand dad's day this was the first hog killing weather.
I've got to dig out my winter coat, don't know where it is at this point but believe you me, I'll find it. If you're enduring this type of weather, hunker down & keep warm!
