The extreme cold could last into next week.  Newtown’s First Selectman and the Emergency Management Office urge residents to make appropriate preparations to ensure personal safety and readiness.  They are also asking that residents check on any elderly or frail neighbors to be certain they are doing OK in this weather.  Designated warming centers in Newtown include the Library, but the facility will be closed Sunday and Monday for New Years.  Edmond Town Hall has several movies and activities this weekend.  The Municipal Center and the Newtown Senior Center are typically open Monday through Friday.
