Freezing Cold Mid April In North Texas

I foolishly thought I was done with winter, with winter not returning til next December.

Well.

I thought wrong.

Mid April, with the outer world scheduled to be chilled to below freezing tonight.

What happened to March roaring in like a lion and leaving like a lamb? And April showers bringing May flowers.

Okay, we do already have that flower thing happened. Will the blooming wildflowers survive being frozen tonight?
