Frisco TX anticipates its first FREEZE tonight (Sunday 11/27/2011). Temperature is expected to drop to about 27 degrees Fahrenheit.
Remember to protect your exterior faucets with outdoor faucet covers. You can purchase them at Home Depot or Lowes for a few dollars each.
Also, before going to sleep tonight, slow drip your indoor faucets that are on exterior walls.
Last but not least, check your sprinkler system to not come on.
