No Picture

The Harris County Office of Homeland Security and Emergency Management has been closely monitoring a potential freezing event that is forecasted to impact Texas over the Christmas weekend. Dan Reilly with the National Weather Service reached out this morning with the following memo and authorized us to share their updates with our industry partners. Please feel free to share with your member companies.

Updates will be provided as they become available.

Important Information:

  • A very cold air mass will likely push into Texas on or around December 23rd and linger over the area until December 28th.
  • Still uncertain how cold it will get but potential exists for a period of sub-freezing temperatures during that period.
  • Attached slides show model blend averages and spread in solutions. The spread is a measure of the uncertainty.
  • We will know more about exactly how cold, how long as we get closer.
