It is a cold, windy, and wet day in north Texas.  Here it is May and the high tomorrow is forecast to be 50° which is rare for Texas in late spring.  With this type of weather, I doubt people will be using their outdoor spas and will be using spa covers to keep out any debris that these strong wind gusts are blowing around.  But in Texas, weather changes quickly and it could be nearly a 100° in a few days!
