[QUOTE="KPRC2, post: 26768, member: 148"] Hopefully, you’ve heard that our Mother’s Day weekend is going to bring a motherload of heat! Storms expected Thursday will push east by Friday. That opens the door for a strong southwest wind to kick in over the weekend. Why is that so hot? Because when you compress air you heat it up.
