It looks like cold weather has made its way into Central Florida again. Disney decided to close Blizzard Beach in light of the weather. The water park was closed on Wednesday, January 17th and will remain closed through Friday, January 19th. It is currently expected to re-open on Saturday, January 20th.  The temperatures are set to be in the 30s to 40s with the cold front that will be in the area. Typhoon Lagoon is already closed due to annual maintenance and refurbishment, so it is not impacted by this closure.
The water parks typically close when the temperatures are expected to be too low to be comfortable. Many of the pools and some attractions are heated, but moving from attraction to attraction could be quite chilly.  Disney keeps guest safety in mind as well as the operational costs.  The cold weather decreases the likelihood of very many guests attempting to come to the water park, making it a huge waste of operational resources to staff the park for low attendance.
We will keep you all updated on any changes to the schedule. We hope all of you at Walt Disney World over the next few days stay warm out there and enjoy the cooler temps!
