How the warning unfolded

The weather service first flagged the risk with a Freeze Watch issued Friday afternoon, October 16, warning that sub-freezing readings were possible by early Sunday NWS. That watch was cancelled just after midnight Saturday and replaced right away with a Freeze Warning as forecasters grew more confident in the cold NWS +1. The warning was updated several times through Saturday, including the version reported here issued at 2:54 p.m., and again overnight into Sunday NWS +2. By 9:02 a.m. Sunday, the weather service said temperatures were warming, and the warning expired a short time later NWS.
